Fig. 2 is a schematic structural diagram of a showerhead according to an embodiment of the present invention. The spray head 4 comprises an end cover part 16, one end of the end cover part 16 is used for being connected with the pressurizing device 1, the other end of the end cover part 16 is connected with one end of the medicine storage bin 8, specifically, the two sides of the end cover part 16 can be provided with external threads, internal threads or buckle structures and the like, the structures of the two sides can be the same or different, so that the spray head 4 can be connected with the pressurizing device 1 through the end cover part 16, and the end cover threads 5 can be arranged outside the end cover part 16, so that a user can screw or loosen the end cover part 16. In addition, the end cover part 16 also has the function of a bin cover of the medicine storage bin 8, so that the medicine storage bin 8 is separated from the pressurizing device 1, and after the pressurizing device 1 and the medicine storage bin 8 are separated as required by a user, the medicine 19 in the medicine storage bin 8 can be prevented from overflowing.

Easily understand, in order to spout into patient's nasal cavity with 19 accuracies of medicine, still need suitable nozzle, for example, this scheme adopts soft nozzle 18, and this soft nozzle 18 can be medical silica gel material, can take place deformation easily, conveniently pushes the nasal cavity inside, can follow nasal cavity inner structure and take place corresponding deformation. Specifically, the other end of the drug storage bin 8 can be connected with the soft nozzle 18, so that the drug 19 can be well sprayed to a specified position in the deep nasal cavity, for example, the drug is sprayed to the position 21 of the olfactory fissure region in the nasal vestibule as shown in fig. 11.

Fig. 3 is a schematic view of an internal structure of a showerhead according to an embodiment of the present invention. The end cover portion 16 is also provided with a pressurizing hole 6. The pressurizing device 1 is communicated with the medicine storage bin 8 through the pressurizing hole 6, so that the pressure airflow generated in the pressurizing device 1 can be introduced into the medicine storage bin 8 to eject the medicine 19 in the medicine storage bin 8. Generally, the pressurizing hole 6 cannot be set too large in order to ensure that the air pressure applied by the pressurizing device 1 to the drug storage 8 can satisfy the requirement for ejecting the drug 19.

Fig. 4 is a schematic structural view of a medicine storage bin and a soft nozzle according to an embodiment of the present invention. It can be seen that, in order to be able to contain enough medicine 19, the cartridge 8 may be a hollow cylinder as shown in fig. 3, which is formed by the outer wall 7 and includes the cavity 17 (of course, other shapes are also possible in practical applications, and this is merely for illustration and does not constitute a limitation to the present invention). The other end of the medicine storage bin 8 is provided with a medicine bin baffle 10 which is used for separating the medicine storage bin 8 from the soft nozzle 18 for space isolation, communicating the medicine storage bin when medicine needs to be sprayed, and isolating the medicine storage bin when medicine is added. Meanwhile, a nozzle baffle 22 is arranged on the soft nozzle 18 at the connection part with the medicine storage bin 8. The medicine bin baffle plate 10 is provided with a medicine outlet hole 9, and the nozzle baffle plate 22 is provided with a medicine inlet hole 12. Therefore, when the medicine 19 in the medicine storage bin 8 is pressurized by the pressurizing device 1, the medicine 19 in the medicine storage bin 8 is ejected after passing through the medicine outlet hole 9 and the medicine inlet hole 12 in sequence. In order to ensure that the pressure for ejecting the medicine 19 is too low, the medicine outlet 9 and the medicine inlet 12 are significantly smaller than the space of the medicine storage bin 8.

Optionally, the cartridge shutter 10 and the nozzle shutter 22 are located on the first axis at the same time, in other words, when the cartridge shutter 10 or the nozzle shutter 22 rotates around the axis, the cartridge shutter 10 and the nozzle shutter 22 do not move relatively. The outlet holes 9 mentioned in the above embodiments are provided on one side of the first axis of the cartridge shutter 10, which does not pass through the outlet holes 9. The medicine inlet hole 12 is provided on one side of the first axis of the nozzle guard 22, which does not pass through the medicine inlet hole 12. The nozzle guard 22 is movably connected to the cartridge guard 10, in other words, the nozzle guard 22 and the cartridge guard 10 can rotate around the first axis, so that the relative position between the medicine outlet 9 and the medicine inlet 12 can be changed, for example, the medicine outlet 9 and the medicine inlet 12 can be completely aligned or completely dislocated by rotation, as shown in fig. 5, which is a schematic diagram of the state of the medicine inlet and the medicine outlet according to the embodiment of the present invention. It will be readily appreciated that in order to align the outlet 9 and inlet 12 holes properly, it is necessary that the outlet 9 and inlet 12 holes be co-axial.

In order to ensure the sealing effect after the soft nozzle 18 is connected with the medicine storage bin 8 and prevent the problems of air leakage or medicine leakage, etc., the medicine bin baffle plate 10 and the nozzle baffle plate 22 are connected through the connecting bin 11.

Alternatively, one end of the soft nozzle 18 is connected to the other end of the nozzle guard 22, and the relative position between the soft nozzle 18 and the nozzle guard 22 is not allowed to change during the use process, so that the soft nozzle 18 and the nozzle guard 22 can be fixedly connected or detachably connected, but the relative rotation or movement does not occur after the connection. The soft nozzle 18 and the inlet 12 are located on the second axis, so that the medicine 19 can be smoothly ejected through the inlet 12 and the soft nozzle 18 during the spraying operation.

In order to facilitate the patient to insert the soft nozzle 18 into the nasal cavity, the soft nozzle 18 is tapered, but a combination of tapered and cylindrical nozzle may be used. The soft nozzle 18 is in a hollow conical shape, and the conical side wall 15 is provided with a medicine spraying hole 14, so that the medicine 19 can be conveniently sprayed to the inner wall of the nasal cavity through the medicine spraying hole 14. Specifically, the length and thickness of the soft nozzle 18 can be adjusted as desired, for example, the soft nozzle 18 of a child applicator is shorter than that of an adult, and the diameter of the soft nozzle 18 is smaller.

In practical applications, the angle between the third axis of the spraying hole 14 and the normal of the tapered sidewall 15 is 5 to 90 °, generally, the size of the spraying hole 14 is 1.5 to 5 mm, the state and type of the sprayed medicine 19 are different, and the size and angle of the corresponding spraying hole 14 are also different. For example, the spray opening 14 required for spraying the liquid medicament 19 is smaller than the spray opening 14 required for spraying the powder medicament 19.

In this application technical scheme, pressure device 1 can be a compressible device, can adopt materials such as plastics, silica gel to make, and the lateral wall can be compressed under the exogenic action for the multilayer fold that is similar to folding fan to produce jet-propelled pressure. During the pressing process, the air flow in the pressurizing means 1 flows from the pressurizing means 1 to the spraying hole 14, and the pressurizing means 1 automatically returns to its original shape after the compression force is released by the patient.

In practical applications, the pressurizing device 1 may further include a conduit 2 and a pressurizing member 13, and the conduit 2 and the pressurizing member 13 may be an integral structure or a detachable structure. Thereby being suitable for the requirements of different using lengths of patients.

In order to prevent the medicament 19 in the cartridge 8 from flowing into the pressurizing means 1, for example, by gravity, or by the medicament 19 flowing into the pressurizing means 1, or by the action of air pressure generated from the cartridge 8 to the pressurizing means 1 during the return of the pressurizing means 1, the medicament 19 is flowed into the pressurizing means 1, a one-way valve 3 is provided in the conduit 2. The one-way valve 3 can be opened only toward the drug storage bin 8, and can effectively prevent the drug 19 from flowing toward the pressurizing device 1.

The olfactive region medicine feeder comprises a pressurizing device for providing a medicine spraying power source and a spray head with a soft nozzle respectively. With the storage medicine storehouse setting in the middle of the shower nozzle, set up with pressure device separation, with the storage medicine storehouse setting in the position nearest apart from soft nozzle to the messenger will be located pressure device terminally through strong air current medicine is sent to the nasal cavity in the storage medicine storehouse inside to reach and smells schizont position, makes on the one hand that the medicine can be more thorough send into the nasal cavity inside to reach and smell schizont position, thereby dose more accurate, on the other hand avoids during medicine gets into pressure device's the air flow pipeline, the medicine in the storage medicine storehouse is clean more convenient. Moreover, the medicine can be repeatedly added by opening the end cover part of the medicine storage bin; the shape of the soft nozzle can be changed at will, which is more beneficial to extending into the nasal cavity (such as nasal vestibule) for the administration in the olfactory fissure region.

The embodiment of the invention also provides a method for administering the drug based on the olfactive region administration device. As shown in fig. 6, the method includes the steps of:

601: the pressurizing means 1 and the spray head 4 in the dispenser are separated.

602: the end cover part 16 of the spray head 4 is opened, and the medicine 19 is put into the medicine storage bin 8 through the end of the medicine storage bin 8 connected with the end cover part 16.

When the medicine is added into the medicine storage bin 8 as shown in fig. 7, the medicine storage bin 8 is arranged in the spray head 4, the user firstly needs to separate the pressurizing device 1 from the spray head 4, then opens the end cover part 16 of the medicine storage bin 8, pours the medicine 19 into the medicine storage bin 8, and then fixes the end cover part 16 to the medicine storage bin 8 again as shown in fig. 8, and at this time, the medicine outlet hole 9 and the medicine inlet hole 12 are required to be arranged in a staggered manner. The pressurizing device 1 is then combined with the ejection head 4 as shown in fig. 9, and the catheter port 20 on the catheter 2 enters the drug 19 in the cavity 17 through the pressurizing hole 6 on the end cap portion 16 as shown in fig. 10. When the soft nozzle 18 is used, the soft nozzle 18 rotates relative to the cavity 17, so that the medicine inlet hole 12 of the nozzle baffle plate 22 on the soft nozzle 18 and the medicine outlet hole 9 on the medicine bin baffle plate 10 on the cavity 17 are in a coaxial state, and one end of the cavity 17 is opened. The procedure for applying the drug into the nasal cavity is shown in fig. 11 and 12. As shown in fig. 11, the patient will operate the pressurizing device 1, the catheter 2 and the spray head 4 according to the arrow method in the figure, and the soft nozzle 18 on the spray head 4 is placed in the nasal vestibule 21 of the patient. As shown in fig. 12, the pressurizing device 1 is pressed in the direction of the arrow in the figure so that air enters the spray head 4 through the conduit 2, and the medicine 19 in the spray head 4 is sprayed into the nasal vestibule 21 from the soft nozzle 18, thereby completing the administration of the medicine at the nasal cavity including the position of the olfactory fissure. The patient may select the location of the particular spray 19 of medicament as desired. The patient can adjust the depth of the soft nozzle 18 inserted into the nasal cavity and the spraying angle.

Before the medicine is added into the medicine storage bin 8, in order to prevent the medicine 19 from flowing out of the soft nozzle 18, the medicine inlet hole 12 of the nozzle baffle plate 22 on the soft nozzle 18 and the medicine outlet hole 9 of the current medicine storage bin 8 need to be adjusted to be in a mutual dislocation position, in other words, the medicine outlet hole 9 and the medicine inlet hole 12 need to be respectively arranged on different axes, and the indirect distance between the axes of the medicine outlet hole 9 and the medicine inlet hole 12 is larger than the diameter of any one hole.

The pressurizing means 1 is connected to the soft nozzle 18 and the catheter port 20 of the catheter 2 is inserted into the drug 19. The medicine 19 in the medicine storage bin 8 is sprayed out through the spraying hole 14 on the side wall of the soft nozzle 18 connected with the medicine storage bin 8 by pressing the pressurizing device 1. In the process of adding medicine, the relative positions of the medicine outlet hole 9 on the medicine bin baffle plate 10 and the medicine inlet hole 12 on the nozzle baffle plate 22 are adjusted firstly, so that the medicine inlet hole 12 and the medicine outlet hole 9 are on the same axis.
