Detailed Description

The ostomy bag is a storage container for the excrement of a patient after anorectal ostomy operation, and the current common ostomy bags comprise a waistband type ostomy bag and a sticking type ostomy bag. The development of the ostomy bag for many years improves and improves the postoperative life quality of patients with ostomy, but has the defects that the cleaning is difficult and the exhaust is troublesome.

The basic structure of the ostomy bag comprises an adhesive ring 1 which is used for being adhered to the outer ring of the abdominal ostomy opening and an ostomy bag body 2 which is communicated with an inner hole 11 of the adhesive ring 1. When the adhesive ring is used, the inner hole 11 at the center of the adhesive ring 1 is made into an expansion incision according to the size of the artificial fistula, and the adhesive ring 1 is adhered to the outer ring of the artificial fistula corresponding to the position of the artificial fistula.

In the case of an open ostomy bag, a discharge opening 3 and a closure for blocking or clipping the discharge opening 3 are provided below the ostomy bag body 2. The drainage port 3 is blocked by a closer, so that the inner cavity of the ostomy bag body 2 is called a closed cavity. Urine or feces excreted by the body will be excreted through the stoma into the inner cavity of the ostomy bag body 2. After the inner cavity of the ostomy bag body 2 is full, the closer is opened to open the discharge port 3, urine or excrement gathered in the inner cavity of the ostomy bag body 2 can be discharged through the discharge port 3, after the urine or excrement gathered in the inner cavity of the ostomy bag body 2 is emptied, the flushing pipe is inserted into the inner cavity of the ostomy bag body 2 through the discharge port 3 for flushing, and after flushing, the closer can be reused to block the discharge port 3 to enter the next service cycle. The closure may comprise various forms, such as clips, seals, etc., as long as the blocking of the discharge opening 3 is achieved, and is not to be mentioned here.

The invention will be further explained with reference to the accompanying drawings and embodiments, and the ostomy bag convenient for flushing and exhausting comprises an adhesive ring 1 for adhering to the outer ring of the abdominal ostomy, an ostomy bag body 2 communicated with an inner hole 11 of the adhesive ring 1, an excretion hole 3 below the ostomy bag body 2 or provided with a closer for blocking or clamping the excretion hole 3. This is the basic structure of an ostomy bag, and its use is not to be mentioned here.

According to the ostomy bag convenient to wash and exhaust, the inner layer of the side, close to the skin, of the ostomy bag body 2 is not different from that of the existing ostomy bag, and is provided with the adhesive ring 1, the excretory opening 3 and the closer for blocking or clamping the excretory opening 3.

When the ostomy bag is used, gas generated in the intestinal cavity can enter the ostomy bag cavity through the ostomy opening, so that the ostomy bag cavity is enlarged, and if the gas in the ostomy bag cavity is discharged, only the closer of the excretion opening 3 of the ostomy bag can be opened, and the operation is very complicated. Manufacturers also provide holes and caps on the outer film 21 of the ostomy bag for venting air. However, the exhaust operation needs to be actively opened, the exhaust port needs to be upward during operation, and the exhaust port needs to be carefully sealed again after exhaust, otherwise, the risk of excrement overflowing is caused, and the operation is very inconvenient.

As shown in fig. 1, 2, 3 and 7, the structure of the outer layer film 21 of the present invention is schematically illustrated. The outer layer film 21 of the ostomy bag body 2 is provided with an exhaust hole 22, the outer ring of the exhaust hole 22 is sealed with a water-blocking exhaust diaphragm 23, so that the gas in the ostomy bag body 2 can be exhausted through the water-blocking exhaust diaphragm 23, and the liquid in the ostomy bag body 2 can not be exhausted through the water-blocking exhaust diaphragm 23. The most common material of the water-blocking and air-exhausting membrane 23 is an ePTFE microporous membrane, the component of which is expanded polytetrafluoroethylene, the water-blocking and air-exhausting membrane has stable chemical performance, wide temperature application range and no aging. Each square inch of the membrane surface has more than 90 billion micropores, the diameter of each micropore is 0.2-1.0 mu m, the diameter is far 10000 times smaller than the smallest water drop, and even light fog cannot pass through the micropores. But is more than 700 times larger than the water vapor molecules, and the gas can easily pass through. Unique properties of liquid barrier but gas venting are created. When the ostomy bag is normally used, the excretion opening 3 is in a closed state under the action of the closer, and gas in the intestinal tract can not be discharged through the closed excretion opening 3. The outer film 21 is provided with an exhaust hole 22, and a water-blocking exhaust film 23 is provided to completely cover the exhaust hole 22. Thus, the gas generated in the intestinal tract and accumulated in the cavity of the ostomy bag can be discharged out of the cavity of the ostomy bag through the vent hole 22 arranged on the outer layer film 21 and then the water-blocking vent film 23. Therefore, the gas generated in the middle intestinal tract can be unconsciously discharged out of the ostomy bag cavity through the water-blocking exhaust membrane 23 without active operation; moreover, liquid and solid excrement in the ostomy bag cannot be leaked.

In specific implementation, the water-blocking and air-venting membrane 23 can be bonded to the outer membrane 21 by various means such as adhesion, ultrasonic welding, heat-seal welding, etc., and must completely cover the air vent 22. Of course, the exhaust hole 22 may be a single hole or a plurality of holes, as long as the water-blocking exhaust membrane 23 completely covers the outer ring of the exhaust hole 22.

Furthermore, the ostomy bag convenient to wash and exhaust further comprises a sealing film cover sheet 24, wherein one side of the sealing film cover sheet 24 is coated with an adhesive layer which can be adhered to the outer side of the water-blocking and air-exhausting membrane 23 to block the air in the ostomy bag body 2 from being exhausted from the air exhaust hole 22. The sealing membrane cover sheet 24 should be made of a dense material that is impermeable to both gas and liquid, including PE membranes, PVC membranes, silicone membranes, and the like. The outer ring part of one side of the sealing film cover plate 24 or the whole surface of one side is coated with the pasting layer, so that the sealing film cover plate 24 can be conveniently and completely pasted and covered outside the water-blocking exhaust diaphragm 23, the ventilation function of the water-blocking exhaust diaphragm 23 can be blocked, and the air discharge time in the ostomy bag can be actively and effectively controlled. For example, the sealing film cover sheet 24 can be adhered to the outside of the water and air blocking film 23 to block the air in the ostomy bag from being discharged, thereby preventing odor and preventing the atmosphere from being damaged in important places or time periods, such as: eating, special activities, important anniversaries, etc. In non-critical situations or time periods, the sealing film cover sheet 24 can be peeled off from the outer side of the water-blocking and air-releasing film sheet 23 and adhered to the nearby outer layer film 21, and for convenience of use, the viscosity of the adhering layer of the sealing film cover sheet 24 should be controlled, so that the sealing film cover sheet 24 cannot be too tight to be peeled off easily, even the sealing film cover sheet 24 is damaged when being peeled off, and the sealing effect of the water-blocking and air-releasing film sheet 23 cannot be sealed due to too loose air.

Further, as shown in fig. 3, 4, 5 and 6, a film tube 6 is arranged on one side of the ostomy bag body 2 away from the drain outlet 3, the inner cavity of the film tube 6 is communicated with the inner cavity of the ostomy bag body 2 and the outside, and the outer wall of the film tube 6 is hermetically connected with the ostomy bag body 2; one side of the film tube 6 is a double-film tube 61 which is contained in the cavity of the ostomy bag body 2, the other side end part of the film tube 6 is provided with a double-film opening 62 which is arranged outside the ostomy bag body 2, and a matched film opening sealing body 63 is arranged to close the double-film opening 62. The film tube 6 is preferably arranged at the side of the ostomy bag body 2 remote from the excretion opening 3, a perforation is arranged at the end part of the side remote from the excretion opening 3, and the outer edge of the film tube 6 is connected with the inner edge of the perforation in a sealing way. The film tube 6 is a cylinder film with two sides sealed and clung together, which is essentially the edge of two layers of soft films are adhered together. The end of the film tube 6 on one side is enclosed in the cavity of the ostomy pouch body 2 to form a double-film tube 61. The other end of the membrane tube 6 is outside the inner cavity of the ostomy bag body 2, forming an opening for communicating the membrane tube 6 with the outside, i.e. a double membrane port 62.

Generally, when a certain amount of contents is contained in the ostomy bag, a certain pressure is applied to the ostomy bag, the double-film tube 61 is in a tightly closed state under the action of the pressure and the bonding action of the two films of the double-film tube 61, the tightly closed state is maintained no matter how much positive pressure is applied to the ostomy bag, and feces in the ostomy bag cannot spill out.

When needed, the cleaning tube can be placed into the double-membrane tube 61 through the double-membrane opening 62, the hard cleaning tube can prop the double-membrane tube 61 open and enter the cavity of the ostomy bag, and the cleaning liquid can be injected into the ostomy bag through the cleaning tube, so that the ostomy bag can be cleaned. The double-membrane opening 62 is a soft membrane opening and has better elasticity, and the hole in the middle of the double-membrane opening is smaller than the cleaning pipe. During cleaning, the sealing films at the edges of the double-film openings 62 can tightly wrap the cleaning pipe to seal the cleaning pipe, so that excrement is prevented from entering the double-film pipe 61 and overflowing through the double-film openings 62. Meanwhile, the inside of the ostomy bag is in a positive pressure state during cleaning, and the double-membrane tube 61 can be tightly attached to the outer wall of the cleaning tube under the action of the positive pressure, so that the sealing effect is achieved, and the excrement is prevented from entering the double-membrane tube 61 and overflowing through the double-membrane opening 62. We have tried out and tested repeatedly during the design, and the sealing effect of the membrane tube 6 is very satisfactory no matter in the resting state or in the cleaning state. On the other hand, a matching film port sealing body 63 is arranged at the tail part of the double film port 62 and outside the outer layer film 21 of the ostomy bag body 2, so that the double film port 62 can be closed. Furthermore, the membrane port sealing body 63 can close the double membrane port 62 when the bag is not washed, so that double insurance is realized, and a strong psychological hint is given to a patient that the content of the ostomy bag is not possible to overflow.

Further, as shown in fig. 7, 8 and 9, the ostomy pouch body 2 is provided with a flushing port 5 through the outer film 21 of the ostomy pouch body 2 at the edge of one side away from the excretion port 3, and a sealing body 51 for closing the flushing port 5; the flushing port 5 is communicated with the inner cavity of the ostomy bag body 2, a jet flushing passage 52 is arranged along the inner side edge of the ostomy bag body 2, and a plurality of jet holes 53 are arranged on the jet flushing passage 52 in the direction of pointing to the discharge port 3 of the ostomy bag body 2. Thus, a cleaning channel surrounding the upper part of the ostomy bag body 2 is formed through the jet flushing channel 52, when the ostomy bag needs to be cleaned, the flushing channel is connected through the flushing port 5, the cleaning liquid enters the jet flushing channel 52 surrounding the upper side of the ostomy bag body 2 through the flushing port 5, a plurality of jet holes 53 are arranged in the direction pointing to the excretion hole 3 from the jet flushing channel 52 and flow out, certain pressure is given, jet flushing like showering is formed, and a relatively comprehensive cleaning effect is formed on the inner wall of the ostomy bag.

The sealing body 51 has a plurality of forms and can be a plug, and the plug can block the flushing port 5 after being plugged into the flushing port 5; the washing opening 5 can be clamped and closed from the outer side wall of the washing opening 5 by a clamp to form a blocking to the washing opening 5. Other forms are not listed as long as a temporary block is formed for the flushing port 5.

Referring to fig. 10, 11, 12 and 13, the process for manufacturing an ostomy bag with easy rinsing and venting is shown, including the processes of the two embodiments of fig. 3 and 7, and will be explained with reference to the embodiment of fig. 7.

The processes of S1 and S2 may be roughly shown in fig. 10 and 12.

As shown in the S1 process: the inner film 25 of the ostomy bag body 2 is gradually unwound at a uniform speed, stops at intervals, and cuts a hole at a position corresponding to the inner hole 11 of the ostomy bag body 2 to form a film inner hole 11'. The inner layer film 25 for manufacturing the ostomy bag body 2 is a whole roll of soft film, is coiled and wound into a film-forming reel, is placed on a bracket, is gradually unfolded towards the process flow direction, and is slowly extended and stopped at intervals under the control of a motor. When the inner film strip stops, the inner film 25 is unfolded to correspond to the upper surface of the operating platform for cutting the inner hole 11, and the inner film 25 is subjected to inner hole 11 cutting under the ordered control of the hole cutting die to form the inner hole 11' of the film strip. And the cut circular membrane is removed to form an inner membrane 25 film roll which is full of inner holes 11' in the membrane.

As shown in the S2 process: the outer film 21 of the ostomy bag body 2 is gradually unwound at a uniform speed, stops at intervals, and cuts at the position corresponding to the exhaust hole 22 of the ostomy bag body 2 to form a film with an exhaust hole 22'. The S2 process is highly similar to the S1 process except for the differences in the size and location of the cut holes. And will not be described in detail herein. As shown in the S3 process: and (3) oppositely overlapping the outer layer film 21 unfolded film belt with the exhaust holes 22 'in the cut film belt in the step (S2) and the inner layer film 25 unfolded film belt with the inner holes 11' in the cut film belt in the step (S1) to form a double-layer film belt 4, and advancing at a uniform speed and stopping at intervals. In this process, the emphasis is on the alignment and overlapping of the developed film strip of the outer layer film 21 with the vent holes 22 'in S2 and the film strip of the inner layer film 25 with the inner holes 11' in S1, and the "alignment and overlapping" is not only the alignment of the developed film strip of the outer layer film 21 with the vent holes 22 'and the film strip of the inner layer film 25 with the inner holes 11', but also the following points must be achieved: firstly, the width of the film roll of the inner layer 25 of the bag body 2 of the ostomy bag body of the S1 process is completely consistent with that of the film roll of the outer layer 21 of the bag body 2 of the ostomy bag body of S2; the unwinding speed of the film roll of the inner layer 25 of the ostomy bag body 2 in the S1 process and the unwinding speed of the film roll of the outer layer 21 of the ostomy bag body 2 in the S2 process are required to be highly consistent; thirdly, the inner hole 11 'of the film belt formed by cutting the inner film 25 of the S1 process after being unfolded and the air vent 22' of the film belt formed by cutting the outer film 21 of the S2 process after being unfolded must be in one-to-one correspondence and matched in position; the position adaptation is not that the inner holes 11 'of the film belts are aligned with the vent holes 22', but the vent holes 22 of the outer layer film 21 and the inner holes 11 of the inner layer film 25 of the inner layer structure of the ostomy bag body 2 are matched one by one according to the position relationship; in the drawing of this embodiment, only one vent hole 22 and one inner hole 11 are cut in correspondence with each other after the roll of the outer film 21 and the roll of the inner film 25 are unwound. However, in specific implementation, the width of the outer layer film 21 roll and the inner layer film 25 roll can be increased by several times, and when corresponding holes are cut, a plurality of holes can be cut at the position of the hole cutting operation platform at the same time, and a plurality of exhaust holes 22 and inner holes 11 which are matched one by one are formed on the outer layer film 21 roll and the inner layer film 25 roll respectively; stopping the outer layer film 21 roll and the inner layer film 25 roll at the same time, and stopping time intervals are completely the same, so that the subsequent position deviation caused by the difference of the stopping time intervals after the initial hole cutting positions are matched is avoided; fifthly, when the outer film roll 21 and the inner film roll 25 are unfolded on the operating table, large errors in the front and back or left and right positions are avoided.

In order to ensure the deviation caused by the dislocation of the film tapes when the outer film 21 roll and the inner film 25 roll are unfolded in the operating table, a plurality of positioning holes can be formed on the outer film 21 roll and the inner film 25 roll along the long axis edge of the film tapes, especially when the outer film 21 roll and the inner film 25 roll are cut to form the film tape inner hole 11 'and the tape exhaust hole 22', the same cutting die is used for respectively cutting the edges of the outer film 21 roll and the inner film 25 roll to form the positioning holes, namely: positioning hole cutting dies are arranged on two sides of the film strip inner hole 11 'corresponding to the edge of the outer layer film 21 film roll, so that the film strip inner hole 11' and the positioning holes are formed by synchronous cutting; similarly, on both sides of the hole cutting die with the vent hole 22 ', a positioning hole cutting die is made corresponding to the edge of the inner layer film 25 roll, so that the vent hole 22' and the positioning hole are formed by synchronous cutting. The outer film roll 21 and the inner film roll 25 are required to be completely consistent along a plurality of continuous positioning holes formed by cutting the long-axis edges of the film strips and can be overlapped correspondingly. When the outer layer film 21 and the inner layer film 25 are overlapped and aligned one by one, the positions of the inner holes 11 'of the film belt and the air exhaust holes 22' of the belt are also matched and aligned one by one, so that the position relationship of the inner holes 11 'of the film belt and the air exhaust holes 22' of the inner layer film 25 of the ostomy bag body 2 is consistent with the position relationship of the inner holes 11 of the inner layer film 25 of the ostomy bag body 2 and the air exhaust holes 22 of the outer layer film 21.

Correspondingly, the conveyor belt is sleeved at the edge of the operating platform, corresponding positioning columns are arranged at the edge of the conveyor belt, positioning holes at the edges of the outer layer film 21 roll and the inner layer film 25 roll are respectively sleeved at the positioning columns at the edge of the conveyor belt in a sleeved mode, under the action of the positioning columns and the positioning holes, synchronous movement of the outer layer film 21 roll and the inner layer film 25 roll is guaranteed, position deviation of the outer layer film 21 roll and the inner layer film 25 roll is avoided, and film belt inner holes 11 'of the inner layer film 25 roll and belt exhaust holes 22' of the outer layer film 21 roll are guaranteed to be matched and aligned one by one.

As shown in figures 11, 12 and 13, during the pause interval of the interval pause of the double-layer film strip 4, continuous ultrasonic or heat bonding matching the shape of the ostomy bag 2 is carried out on the two side edges of the corresponding ostomy bag 2 to form two side shape bonding lines 26. The arrangement of the outline bonding lines 26 at the two sides of the ostomy bag body 2 needs to be set by referring to the positions of the inner holes 11 'and the air vents 22' of the film belt, so that after the welding grinding tool of the outline bonding lines 26 at the two sides of the ostomy bag body 2 is welded to the double-layer film belt 4, the position relationship of the inner holes 11 'of the film belt, the air vents 22' and the outline bonding lines 26 at the two sides is consistent with the position relationship of the inner holes 11 of the ostomy bag body 2, the air vents 22 and the edges at the two sides of the ostomy bag. It should be reminded that the outline of the outline bonding lines 26 on both sides is the same as that of the edges of the ostomy bag, but the width of the outline bonding lines 26 on both sides is larger than that of the edge bonding lines of the ostomy bag, and the width of the outline bonding lines 26 on both sides is preferably 3-5 mm. The outline bonding lines 26 on the two sides are bent outwards at the outline edge corresponding to one side of the ostomy bag body 2 far away from the excretion opening 3 to form the washing bonding line 26-1 corresponding to the washing opening 5, so that after the welding grinding tool corresponding to the washing bonding line 26-1 welds the double-layer film strip 4, the edge bonding on the two sides corresponding to the washing opening 5 is formed on the double-layer film strip 4 after the washing bonding lines 26-1 on the two sides are welded, and the welding width of the washing bonding lines 26-1 on the two sides is also 3-5mm, which is optimal. The outline bonding lines 26 on both sides are interrupted at the position of the ostomy pouch body 2 corresponding to the excretion opening 3 to form bonding line vacancies 26-2 corresponding to the excretion opening 3, so that after the welding grinding tool corresponding to both sides of the bonding line vacancies 26-2 welds the double-layer film strip 4, the bonding line vacancies 26-2 form a welding gap corresponding to the excretion opening 3 on the double-layer film strip 4.

As shown in figures 11, 13 and 14, during the pause interval of the intermittent pause of the double-layer film strip 4, a parallel ultrasonic or heat-sealing bond is made 3-5mm inside the outline bond line 26 corresponding to the side of the ostomy bag body 2 remote from the discharge opening 3, forming a spray bond line 26-3. The spray bonding line 26-3 is a discontinuous bonding line, the discontinuous interval is 1-3mm, and the tail ends of the two sides of the spray bonding line 26-3 are respectively connected with the appearance bonding lines 26 of the two sides. In practice, the spray bonding line 26-3 and the outline bonding line 26 are performed ultrasonically or heat-sealing at the same welding station and are performed simultaneously by the same ultrasonic or heat-sealing die. After the ultrasonic or heat bonding of the outline bonding line 26 and the spray bonding line 26-3 is completed, a pipe line formed by the outline bonding line 26 and the spray bonding line 26-3 as boundary bonding lines and the outer film 21 and the inner film 25 as outer and inner films, namely a prototype of the spray rinsing path 52, is formed on the side of the ostomy bag body 2 away from the excretion opening 3. Only the contour bonding line 26 is continuous bonding, so that the inner cavity of the ostomy bag body 2 is isolated from the outside; the spray bonding line 26-3 is intermittent bonding, and the intermittent gap is 1-3mm, so that a plurality of spray holes 53 are formed.

Thus, a plurality of models of the ostomy bag body 2 with the outline bonding line 26 as the boundary are formed on the double-layer film tape 4, the model of the ostomy bag body 2 is formed by rolling the outer film 21 as the outer film, rolling the inner film 25 as the inner film, forming the model of the discharge port 3 with the bonding line vacancy 26-2 at one end, forming the model of the jet flushing passage 52 with the outline bonding line 26 and the jet bonding line 26-3 at the other end, forming the model of the flushing port 5 with the flushing bonding line 26-1, forming the inner hole 11 with the exhaust hole 22 ' at the corresponding position of the outer film 21, forming the model of the exhaust hole 22 with the inner hole 11 ' of the film tape at the corresponding position of the inner film 25, and forming one model of the exhaust hole 22 with the inner hole 11 ' of the film tape at the corresponding position of the inner film 25

The blank of the ostomy pouch 2 is attached to the double film tape 4 as shown in figure 7. Compared with the finished product, the prototype of the ostomy pouch body 2 is only short of the water-blocking and air-releasing film 23 and the sealing film cover sheet 24 on the outer film 21 and only short of the adhesive ring 1 on the inner film 25.

As shown in fig. 11, 13, and 14, the process shown in S4: while the double-layer film tape 4 is stopped, the outer edge of the prototype ostomy bag body 2 is cut along the cutting line 7 corresponding to the shape of the ostomy bag body 2 at the outer edge of the outer bonding line 26 on the adjacent operation table in front of the welding operation table in the advancing direction of the double-layer film tape 4 to form a prototype ostomy bag 2-1. The cutting operation of the cutting line 7 is also completed by a die, and the cutting line 7 of the die knife is corresponding to a bonding area formed by bonding the outline bonding line 26 which is supposed to fall on the outer side of the prototype of the stoma bag body 2 corresponding to the double-layer film strip 4 during cutting. The width of the shape bonding line 26 is 3-5mm, and the width of the bonding area corresponding to the edge of the prototype of the ostomy bag body 2 formed on the double-layer film belt 4 is 3-5mm, so that the cutting die corresponding to the cutting line 7 can have an error of 1.5-2.5mm when cutting the edge of the prototype of the ostomy bag body 2, and the integrity of a plurality of prototypes ostomy bags 2-1 formed after cutting can still be ensured. Certainly, correspond 7 cutting operation panels of line of cut should adjust the position also, set up the conveyer belt at cutting operation panel edge to set up the reference column at conveyer belt both sides edge, make the locating hole of 4 both sides of double-deck membrane area ring cover on the reference column one by one, the cutting die of line of cut 7 also should adjust the position, ensure that the cutting edge of line of cut 7 can accurately fall on the rudiment shape edge bonding area of ostomy bag body 2 during the cutting, the optimum position is on the central line that falls on the rudiment shape edge bonding area of ostomy bag body 2. The cutting line 7 is transversely connected at the end parts of the two ends, traverses the tail ends of the prototype of the drain opening 3 and the prototype of the flushing opening 5, and transversely cuts the prototype of the drain opening 3 and the prototype of the flushing opening 5, so that a plurality of prototype manufacturing bags 2-1 are obtained.

After the plurality of blank making bags 2-1 are separated from the double-layer film belt 4 by the cutting die of the cutting line 7, the conveyor belt continues to advance, so that the plurality of blank making bags 2-1 fall off under the action of gravity and enter a semi-finished product container to be collected. The double-layer film belt 4 is formed into a double-layer waste film belt 41 which is fully distributed with holes of the stoma bag body 2 after the embryonic stoma bag 2-1 is removed.

As shown in fig. 10, 11 and 13, the process as S5 shows: the double-layer waste film strip 41 is not directly discarded, but is wound around a rotating drum to form a double-layer waste film strip 41 film roll. The aim is to conveniently control the absolute synchronous unfolding of the inner layer film 25 roll and the outer layer film 21 roll by the simplest method, and avoid the production failure caused by the dislocation of the inner layer film and the outer layer film due to the asynchronous rotation of the inner layer film and the outer layer film of the ostomy bag body 2. The specific method is that a distributor is arranged in a rotary drum in a double-layer waste film belt 41, motors are not arranged on an inner layer film 25 film roll and an outer layer film 21 film roll, when the double-layer waste film belt 41 rotates, the double-layer film belt 4 is stretched and straightened, so that the inner layer film 25 film belt and the outer layer film 21 film belt of the double-layer film belt 4 are kept highly attached and overlapped, meanwhile, the inner layer film 25 film belt and the outer layer film 21 film belt are driven to rotate passively under the matching positioning action of positioning holes and positioning columns on two sides, and finally the fact that the unwinding speeds of the inner layer film 25 film roll and the outer layer film 21 film roll are completely the same and highly synchronous is shown.

Finally, as shown in the S6 process (not shown): the sticking ring 1 is bonded and assembled in the position of the inner hole 11 of the inner layer film 25 of the prototype ostomy bag 2-1, and the water-blocking and air-exhausting membrane 23 and the sealing film cover sheet 24 are bonded and assembled in the position of the air exhaust hole 22 of the outer layer film 21 of the prototype ostomy bag 2-1 to form the semi-finished ostomy bag 2-2. The finished product can be obtained by merely fitting the flushing port 5 of the semi-finished ostomy bag 2-2 with a sealing body 51 for closing the flushing port 5 and fitting the discharge port 3 with a closure for closing the discharge port 3 and bagging.

Similarly, as shown in fig. 12, 13 and 15, the process for manufacturing an ostomy bag with convenient flushing and exhausting comprises the following steps:

and S I: the inner film 25 of the ostomy bag body 2 is gradually unwound at a uniform speed, stops at intervals, and cuts a hole at a position corresponding to the inner hole 11 of the ostomy bag body 2 to form a film inner hole 11'.

And S II: the outer film 21 of the ostomy bag body 2 is gradually unwound at a uniform speed, stops at intervals, and cuts at the position corresponding to the exhaust hole 22 of the ostomy bag body 2 to form a film with an exhaust hole 22'.

And S III: and (3) oppositely overlapping the outer layer film 21 unfolded film belt with the exhaust holes 22 'in the cut film belt in the step II and the inner layer film 25 unfolded film belt with the inner holes 11' in the cut film belt in the step I to form a double-layer film belt 4, advancing at a uniform speed, and stopping at intervals.

The above process steps are exactly the same as before and are not described herein.

As shown in fig. 10 and 15, in the seii process, the double-film tape 4 is intermittently stopped, and a double-film tube 61 is inserted between the inner film 25 and the outer film 21 at a position corresponding to the outer peripheral edge of the ostomy bag at a position corresponding to the edge of the outer peripheral bonding line 26 on the side of the ostomy bag body 2 away from the excretion unit 3, and a sheet-like inert material is previously inserted into the double-film tube 61. A continuous ultrasonic or heat-seal bond matching the profile of the ostomy bag 2 is made at the side edge of the corresponding ostomy bag 2 remote from the excretory opening 3, forming a profile bond line 26 across the double film tube 61. The outline bonding lines 26 on both sides are interrupted at the position of the ostomy pouch body 2 corresponding to the excretion opening 3 to form bonding line vacancies 26-2 corresponding to the excretion opening 3. The double-film tube 61 is formed by bonding two sides of a pre-made double-film, and in a natural state, the upper layer and the lower layer of the double-film tube 61 are tightly attached together to form a double-film structure with the upper layer and the lower layer hermetically attached. The function of the embedded flaky inert material in the double-film-layer tube 61 is to prevent the upper and lower films of the double-film-layer tube 61 from being bonded together when the continuous ultrasonic or heat-seal bonding matched with the appearance of the ostomy bag body 2 is carried out on the side edge of the ostomy bag body 2 far away from the excretion opening 3, and to prevent the double-film-layer tube 61 from being interrupted when the continuous ultrasonic or heat-seal bonding matched with the appearance of the ostomy bag body 2 is carried out on the side edge of the ostomy bag body 2 far away from the excretion opening 3. The sheet-shaped inert material can be made of metal sheets such as copper, steel and the like, or other materials which cannot be bonded can be selected. After the ultrasonic or heat-seal bonding operation which is continuously matched with the appearance of the ostomy bag body 2 is finished at the side edge of the ostomy bag body 2 far away from the excretion opening 3, the upper layer and the lower layer of the double-film tube 61 are respectively sealed and bonded with the outer film 21 film band and the inner film 25 film band of the double-film band 4, so that half of the double-film tube 61 is freely contained in the bonding line cavity of the appearance of the ostomy bag body 2, the other half of the double-film tube is positioned outside the bonding line cavity of the appearance of the ostomy bag body 2, and the double-film tube 61 is hermetically connected with the upper film and the lower film of the double-film band 4 at the crossed part of the double-film tube 61 and the appearance bonding line 26. After the sheet-like inert material is pulled out of the double film tube 61, the inner cavity of the double film tube 61 is connected to the preform for an ostomy bag 2-3 (here, the preform for an ostomy bag 2-3 is still connected to the film tape of the double film tape 4).

As shown in fig. 15, in the esiv process: and cutting the outer edge of the outer shape bonding line 26 corresponding to the cutting line 7 of the shape of the stoma bag body 2 on the adjacent operating platform in front of the welding operating platform in the advancing direction of the double-layer film belt 4 while the double-layer film belt 4 stops to form a stoma bag blank 2-3. A plurality of the prototypes 2-3 of the ostomy bag fall off and enter a semi-finished product container, and the double-layer film belt 4 forms a double-layer waste film belt 41 after the prototypes 2-3 of the ostomy bag are removed. This operation is very similar to the operation of S4 and is not discussed here.

As shown in the sv process: the double-layer waste film belt 41 is wound around a rotary drum to form a double-layer waste film belt 41 film roll;

as shown in the S vi process: the adhering ring 1 is bonded and assembled in a position of an inner hole 11 of an inner layer film 25 of the model 2-3 of the ostomy bag, and the water-blocking and air-exhausting membrane 23 and the sealing film cover plate 24 are bonded and assembled in a position of an air exhaust hole 22 of an outer layer film 21 of the model 2-3 of the ostomy bag to form a semi-finished product 2-4 of the ostomy bag.

The sv process is highly similar to the S5 process, the S vi process and the S6 process, and has been described in detail above, and will not be redundantly described here.

The inner layer film 25 of the ostomy bag body 2, the outer layer film 21 of the ostomy bag body 2 and the double-layer film belt 4 are uniformly unfolded, the interval pause is driven by the same speed control motor, and the rotating speed and the pause time of the speed control motor are controlled by the same chip; the speed control motor is assembled on the rotary drum of the double-layer waste film belt 41 and is used for driving the rotary drum of the double-layer waste film belt 41 to rotate; the uniform speed unfolding and the interval pause of the film roll of the inner layer film 25 of the ostomy bag body 2 and the film roll of the outer layer film 21 of the ostomy bag body 2 are both completed by the passive driving of the rotary drum of the double-layer waste film belt 41. This is the simplest method to ensure that the roll of the inner film 25 of the ostomy bag body 2, the roll of the outer film 21 of the ostomy bag body 2 and the double-layer film belt 4 are unwound at the same speed and stop synchronously. The rotating speed and the pause height of the rotating drum of the double-layer waste film belt 41 can be consistent with those of the rotating drum of the double-layer waste film belt 41 passively by controlling the rotating drum control motor of the double-layer waste film belt 41.

The cutting operation of the film tape inner hole 11 ', the cutting operation of the film tape vent hole 22', the bonding operation of the outline bonding line 26, the bonding operation of the flushing bonding line 26-1, the bonding operation of the bonding line void 26-2, the bonding operation of the spraying bonding line 26-3 and the cutting operation of the outer edge of the outline bonding line 26 corresponding to the cutting line 7 of the outline of the ostomy pouch body 2 are all completed by mechanical operation. Of course, this operation can also be performed manually, but before each cutting operation, it is necessary to determine the matching correspondence of the holes in the inner film 25 and outer film 21 rolls of the ostomy pouch 2, or the exact alignment of the cutting lines with the bonding areas of the profile bonding lines 26. Above-mentioned all operations are all accomplished at the operation panel of conveyer belt interval neutral gear, cutting or welded grinding apparatus and operation panel upper and lower position relation are invariable, just can guarantee all to cut when cutting at every turn and correspond the region that sets up, to peripheral skew when avoiding cutting, lead to the production failure.

When the inner layer film 25 of the ostomy bag body 2, the outer layer film 21 of the ostomy bag body 2 and the double-layer film belt 4 enter and exit the conveying belt and the operating platform, limiting cracks 8 which are 2-3mm larger than the width of the film roll are arranged to limit the deviation of the film roll, and the crack height h of all the limiting cracks 8 is less than 2 mm. The width limitation of the limiting crack 8 can prevent the membrane strip from deviating towards two sides when being unfolded, the crack height h of the limiting crack 8 is limited to be less than 2mm, and the position deviation between the upper membrane strip and the lower membrane strip caused by the membrane strip rising or sinking can be avoided.

In a word, the water-blocking and air-exhausting diaphragm is convenient to exhaust, the air exhaust is controlled by the sealing diaphragm cover plate, the overflow leakage is conveniently avoided by the design of the diaphragm pipe, the bag cavity can be flushed by the jet flushing channel, the excrement is thickened by the water filtering bag, the excretion is convenient, the flushing is convenient by the plastic flushing pipe, the production process can be simple and automatic, the cost is low, the use is convenient, and the practicability is high.
