Background

Regardless of the size of the operation, the skin disinfection must be performed before the operation. Currently, disinfection of preoperative skin is conventionally performed by applying disinfection liquid such as iodophor to surgical field skin, and the common method is as follows: the forceps are used to hold the smearing block, such as a cotton ball, and soak the cotton ball in the disinfectant, and then the smearing disinfection is performed on the skin of the surgical field after the cotton ball is soaked. In order to wet the cotton ball, the disinfectant is generally poured into the vessel in advance, and in order to prevent the disinfectant from being poured into the vessel repeatedly and wasting time due to a small amount of disinfectant, a large amount of disinfectant is generally prepared in the vessel, so that the disinfectant is inevitably wasted.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

As shown in fig. 2, an embodiment of the present invention provides a skin sterilizer for surgery, which includes a bottle body 1, a bottle cap 2, a first rotating shaft 7, a transmission mechanism and a locking mechanism. The bottle body 1 is used for containing disinfectant, such as iodophor or medical alcohol lamp. The bottle cap 2 is used for covering the opening of the bottle body 1. The bottle cap 2 is provided with a sprinkler head 12, a movable handle 3, a first elastic clamping arm 4 and a second elastic clamping arm 5. The movable handle 3 is used for driving the disinfectant in the bottle body 1 to be sprayed out of the spraying head 12 by being pressed. The movable handle 3 can be a rotating handle or the like, and the specific structure of the movable handle 3 is similar to that of a spraying kettle in the prior art, and is not described in detail herein.

As shown in fig. 3, the head of the first elastic clamping arm 4 is provided with a first rotating chuck 6, and the head of the second elastic clamping arm 5 is provided with a second rotating chuck 8. As shown in fig. 2, the first rotatable chuck 6 is opposite to the second rotatable chuck 8, and the two chucks are used for cooperatively holding the rub blocks 10. The aforementioned spray head 12 is used to spray the sanitizing liquid onto the rub block 10. In a specific application example, the spraying head 12 is a fixed part, when the first rotating chuck 6 and the second rotating chuck 8 both clamp the rubbing block 10, the rubbing block 10 is opposite to the spraying opening of the spraying head 12, so that the movable handle 3 is pressed to spray the sterilizing liquid in the bottle body 1 onto the rubbing block 10. Of course, the spray head 12 may be a movable spray head, such as the spray head 12 may be rotatable, and the spray direction may be adjusted as desired, as long as the disinfecting solution is sprayed onto the rub block 10.

Wherein, because the first rotating chuck 6 and the second rotating chuck 8 can both rotate, when the first rotating chuck 6 and the second rotating chuck 8 both clamp the erasing block 10 to be erased on the skin of the patient, the erasing block 10 can rotate, so that the disinfection solution of the erasing block 10 in the circumferential direction can be effectively utilized, and the waste of the disinfection solution can be reduced.

As shown in fig. 3, the first rotating shaft 7 is rotatably disposed on the first elastic clamping arm 4. The first rotating chuck 6 is rotatably provided on a first rotating shaft 7. The movable handle 3 is connected with the first rotating shaft 7 through a transmission mechanism so as to drive the first rotating shaft 7 to rotate when pressed. The locking mechanism described above is used to lock or unlock the first rotating chuck 6. During locking, the first rotating chuck 6 and the first rotating shaft 7 are relatively fixed in the circumferential direction; when unlocked, the locking mechanism releases the circumferential fixation of the first rotating chuck 6, so that the first rotating chuck 6 can rotate relative to the first rotating shaft 7.

In the above example, both the first rotary chuck 6 and the second rotary chuck 8 cooperate to hold the rub blocks 10; then the first rotating chuck 6 is locked through a locking mechanism, so that the first rotating chuck 6 and the first rotating shaft 7 are relatively fixed in the circumferential direction; then the movable handle 3 is pressed, on one hand, the movable handle 3 drives the first rotating shaft 7 to rotate through the transmission mechanism, and the first rotating shaft 7 drives the first rotating chuck 6 and the clamped erasing block 10 to rotate together; the movable handle 3 drives the disinfectant in the bottle body 1 to be sprayed out from the spraying head 12, and the spraying head 12 sprays the disinfectant onto the rotating erasing block 10, so that the efficiency of infiltrating the erasing block 10 with the disinfectant can be improved.

Here, it should be noted that: the aforesaid first elastic clamping arm 4 and the second elastic clamping arm 5 are preferably the arms with longer length, the one ends of the first elastic clamping arm 4 and the second elastic clamping arm 5 are fixed on the bottle cap 2, the other ends of the first elastic clamping arm 4 and the second elastic clamping arm 5 are extended out, so through the structure design, the first elastic clamping arm 4 and the second elastic clamping arm 5 have elasticity, and the other ends of the first elastic clamping arm 4 and the second elastic clamping arm 5 can be relatively opened or reset. First elasticity arm lock 4 and second elasticity arm lock 5 both can be metal material or plastic material etc. preferably, and both can be metal material, so can satisfy sufficient elasticity and structural strength.

In order to realize the function of the transmission mechanism, when the movable handle 3 is pressed, the first rotating shaft 7 can be driven to rotate through the transmission mechanism, and as shown in fig. 3, the transmission mechanism can comprise a connecting rope 13 and a torsion spring. The movable handle 3 is a rotary handle having a rotary shaft 11. The connection cord 13 is wound around the first rotary shaft 7 and connected to the rotary shaft 11 of the movable handle 3. The torsional spring is sleeved on the first rotating shaft 7, one end of the torsional spring is connected with the first elastic clamping arm 4, and the other end of the torsional spring is connected with the first rotating shaft 7. In this example, when the movable handle 3 is pressed, the movable handle 3 drives the rotation shaft 11 to rotate, the rotation shaft 11 drives the first rotation shaft 7 to rotate through the connecting rope 13, and at this time, the torsion spring deforms. When the movable handle 3 is loosened, the torsion spring releases the elasticity, and the first rotating shaft 7 rotates under the action of the torsion spring so as to drive the connecting rope 13 to be wound on the first rotating shaft 7 again.

Aforesaid first pivot 7 can pass first elastic clamping arm 4, and first rotary chuck 6 and torsional spring are located the both sides of carrying on the back mutually of first elastic clamping arm 4 respectively, so have the effect of the first rotary chuck 6 of easy to assemble and torsional spring.

In order to perform the function of the locking mechanism described above, which enables the locking mechanism to lock or unlock the first rotating chuck 6, as shown in fig. 4 and 5, the locking mechanism may include a button 9 provided on the first rotating chuck 6. The first rotating chuck 6 is sleeved on the first rotating shaft 7, and the first rotating chuck 6 is in running fit with the first rotating shaft 7, for example, the two can be in clearance fit or transition fit, etc. The push button 9 is intended to be pressed against the side wall of the first shaft 7 or to release the side wall of the first shaft 7. When the button 9 abuts against the side wall of the first rotating shaft 7, the first rotating shaft 7 and the first rotating chuck 6 are in interference fit to lock the first rotating chuck 6, so that the first rotating chuck 6 and the first rotating shaft 7 are kept relatively fixed, and thus the first rotating shaft 7 can drive the first rotating chuck 6 to rotate together when being driven to rotate. When the button 9 releases the side wall of the first shaft 7, the first rotating jaw 6 is unlocked, so that the first rotating jaw 6 is again in rotating engagement with the first shaft 7, and the first rotating jaw 6 is driven to rotate freely relative to the first shaft 7.

Here, it should be noted that: the structure of the button 9 is prior art and will not be described herein.

As shown in fig. 6, the sidewall of the first rotating shaft 7 may be provided with an inward-concave annular limiting groove 71. The first rotating chuck 6 is provided with a limiting slide block 17, and the limiting slide block 17 is used for being inserted into the annular limiting groove 71 to axially limit the first rotating chuck 6 and prevent the first rotating chuck 6 from loosening from the first rotating shaft 7. Wherein, the spacing slide block 17 is in clearance fit with the annular spacing groove 71 so as not to influence the rotation of the first rotating chuck 6.

As shown in fig. 7, the second rotating chuck 8 may have an air pumping hole 81 penetrating through the head and the tail, the second elastic clamping arm 5 is provided with an air pipe 15 (as shown in fig. 5) communicating with the air pumping hole 81, and the air pipe 15 is provided with an on-off switch. In this example, the air tube 15 may be connected to an external negative pressure device, so that a negative pressure may be formed at the air suction port 81, and when the first rotating chuck 6 and the second rotating chuck 8 are opened relatively and extend into the rubbing block placing box, the negative pressure at the air suction port 81 may rapidly suck the rubbing block 10 between the first rotating chuck 6 and the second rotating chuck 8, so as to accelerate the time for the first rotating chuck 6 and the second rotating chuck 8 to clamp the rubbing block 10.

In order to facilitate installation of the air pipe 15 without affecting rotation of the second rotating clamp 8, preferably, as shown in fig. 5, a second rotating shaft 18 may be fixedly disposed on the second elastic clamp arm 5, the second rotating clamp 8 may be rotatably sleeved on the second rotating shaft 18, and the second rotating clamp 8 and the second rotating shaft 18 may be in clearance fit. As shown in fig. 7, the second rotating shaft 18 is provided with an air passing hole 181 communicating with the air suction opening 81. The air tube 15 is connected to the second shaft 18 and is connected to the air suction port 81 through the air hole 181. In this example, since the second rotating shaft 18 is a fixed shaft, the air tube 15 is connected to the second rotating shaft 18 without affecting the rotation of the second rotating chuck 8, and the air tube 15 can draw air from the air suction opening 81 through the air passing hole 181 on the second rotating shaft 18, so that the second rotating chuck 8 can rotate normally and a negative pressure can be formed at the air suction opening 81.

The surgical skin sterilizer of the present invention may further comprise a driving mechanism for driving the first rotary chuck 6 and the second rotary chuck 8 to be opened relatively, so that the first rotary chuck 6 and the second rotary chuck 8 can hold the rubbing block 10 conveniently.

As shown in fig. 8, the driving mechanism may include a pressing block 14. The first elastic clamping arm 4 is opposite to the second elastic clamping arm 5. As shown in fig. 9, the first elastic clamping arm 4 is provided with a first sliding slot 41, and the second elastic clamping arm 5 is provided with a second sliding slot 51. One side 141 of the pressing block 14 is inserted into the first slide groove 41, and the other side 142 of the pressing block 14 is inserted into the second slide groove 51. The first sliding chute 41 and the second sliding chute 51 are both inclined chutes, and the pressing block 14 is used for being pressed to push the first elastic clamping arm 4 and the second elastic clamping arm 5 to open relatively. In this example, since both the first chute 41 and the second chute 51 are chutes, the distance therebetween gradually decreases along the pressing direction, so that when the pressing block 14 is pushed, the pressing block 14 presses the first elastic clamping arm 4 and the second elastic clamping arm 5, so that the first elastic clamping arm 4 and the second elastic clamping arm 5 gradually open. Preferably, the pressing block 14 may be a trapezoidal block having one side extending into the first sliding groove 41 and the other side extending into the second sliding groove 51.

In order to reduce the influence of the pressing block 14 on the restoration of the two elastic clamping arms, it is preferable that, as shown in fig. 9, a guide slot 21 is formed in the bottle cap 2, a guide convex column 140 is formed on the pressing block 14, and the guide convex column 140 is inserted into the guide slot 21. The guide groove 21 may guide the movement of the pressing block 14. An elastic member, which may be a spring or elastic rubber, may be disposed in the guide groove 21. The elastic member is used for providing the reset force of the pressing block 14, so that when the pressing block 14 is released, the pressing block 14 can be reset quickly under the action of the elastic member, so as to avoid influencing the reset of the first elastic clamping arm 4 and the second elastic clamping arm 5.

The working principle and preferred embodiments of the present invention are described below.

The invention aims to design a skin sterilizer for operation, which is used for firstly connecting an air pipe 15 with external negative pressure equipment; then pushing the pressing block 14, wherein the pressing block 14 presses the first elastic clamping arm 4 and the second elastic clamping arm 5, so that the first elastic clamping arm 4 and the second elastic clamping arm 5 are opened, and the first rotary chuck 6 and the second rotary chuck 8 are also opened relatively; then, the two rotating chucks 6 and 8 extend into the erasing block placing box, an opening and closing switch on the air pipe 15 is opened to form negative pressure at the air pumping hole 81, the negative pressure quickly pumps the erasing block 10 between the first rotating chuck 6 and the second rotating chuck 8, then the pressing block 14 is loosened, the pressing block 14 is quickly reset under the action of the elastic piece, the first elastic clamping arm 4 and the second elastic clamping arm 5 are also reset under the action of self elastic force, and the erasing block 10 is clamped by the first rotating chuck 6 and the second rotating chuck 8; then the button 9 is pressed to lock the first rotating chuck 6, so that the first rotating chuck 6 and the first rotating shaft 7 are kept relatively fixed; then the movable handle 3 is pressed, on one hand, the movable handle 3 drives the first rotating shaft 7 to rotate through the connecting rope 13, and the first rotating shaft 7 drives the first rotating chuck 6 and the clamped erasing block 10 to rotate together; the movable handle 3 drives the disinfectant in the bottle body 1 to be sprayed out from the spraying head 12, and the spraying head 12 sprays the disinfectant onto the rotating erasing block 10, so that the efficiency of infiltrating the erasing block 10 with the disinfectant can be improved.

After the smearing block 10 is completely wetted, the button 9 can be loosened to unlock the first rotating chuck 6, so that the first rotating chuck 6 can freely rotate relative to the first rotating shaft 7; then the rubbing block 10 is moved to the skin of a patient for rubbing, in the rubbing process, the rubbing block 10 can be pushed to rotate by the friction resistance between the rubbing block 10 and the skin of the patient, so that the disinfection solution on the circumference of the rubbing block 10 can be effectively utilized, and the waste of the disinfection solution can be reduced. After the coating is finished, the pressing block 14 is pushed to open the first elastic clamping arm 4 and the second elastic clamping arm 5, so that the first rotating chuck 6 and the second rotating chuck 8 are also relatively opened, and the used coating block 10 can fall off from between the two chucks under the action of self gravity.

Here, it should be noted that: in the case of no conflict, a person skilled in the art may combine the related technical features in the above examples according to actual situations to achieve corresponding technical effects, and details of various combining situations are not described herein.
