Description

Technical Field

[0001] This utility model relates to the field of otolaryngology medication application equipment technology, and in particular to a spray device for otolaryngology. Background Technology

[0002] Otolaryngology includes the ears, nose, and throat, which are some of the parts of the body that are most prone to disease. These diseases are also the most likely to trouble and affect people's normal work and life. If not treated in time, they can easily lead to various other complications.

[0003] For example, Chinese Patent Publication No. (CN215084061U) discloses a spray device for ear, nose, and throat care, which describes: "It includes a base, a storage bottle, and a connector. The storage bottle is embedded in the top of the base, and the connector is fixedly connected to the top of the storage bottle. A drug inlet is connected through the left side of the top of the storage bottle, and a drug delivery tube is embedded in the top of the connector. This invention overcomes the shortcomings of the prior art by setting a ring-shaped distributed lighting lamp and a through-connected spray tube on the mounting plate at one end of the sprayer. When the sprayer is inserted into the patient's ear, nose, and throat, the lighting lamp can illuminate the lesion area, and the drug can be sprayed out through the spray tube. This ensures that medical staff can accurately spray the lesion area without repeatedly adjusting the application angle of the device. This not only effectively avoids secondary damage to the patient's ear, nose, and throat but also avoids patient discomfort, which is beneficial for practical use."

[0004] In summary, existing technologies involve directly applying medication to the nasal cavity or ear canal via a nozzle. However, these devices suffer from the following technical problems: This method of medication application uses pressurized spraying, such as for ear canal application. Direct spraying can cause the medication to enter the inner ear, making it difficult to apply the medication to the affected area and potentially causing severe discomfort due to excessive medication entering the inner ear.

At this time, the medicine applied to the inside of the ear will not enter the inner ear, thereby increasing the convenience of medicine application.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1:

[0033] Please refer to Figures 2-4 A spray device for ear, nose and throat, wherein the positioning and blocking assembly 2 includes a front end conduit 4, a cross positioning frame 5, a rigid guide wire 6, an adaptive telescopic assembly, a telescopic control assembly and a reset assembly, wherein the front end conduit 4 is fixedly connected to the front end of the handle part 1, the front end conduit 4 is connected to the handle part 1, the cross positioning frame 5 is fixedly connected to the middle part of the end of the front end conduit 4 away from the handle part 1, and the rigid guide wire 6 is fixedly connected to the surface of the cross positioning frame 5.

[0034] Specifically, the adaptive telescopic assembly includes a positioning disk 7, elastic elements 8, a telescopic soft membrane 9, and a guide head 10. The end of the rigid guide wire 6 away from the cross positioning frame 5 is fixedly connected to the positioning disk 7. The side of the positioning disk 7 away from the rigid guide wire 6 is fixedly connected to multiple elastic elements 8 in a ring array. Each pair of elastic elements 8 is fixedly connected to a telescopic soft membrane 9. The end of the positioning disk 7 away from the rigid guide wire 6 is fixedly connected to the guide head 10.

[0035] Specifically, the telescopic control assembly includes a drug delivery tube 11, a traction ring 12, a conical hollow extrusion head 13, a traction sleeve 15, a snap-fit ​​positioning block 16, and a positioning ring 17. The surface of the rigid guide wire 6 is fitted with the drug delivery tube 11. One end of the drug delivery tube 11 is fixedly connected to the traction ring 12. The end of the drug delivery tube 11 away from the traction ring 12 is fixedly connected to the conical hollow extrusion head 13. The conical hollow extrusion head 13 is in close contact with the surface of the elastic element 8, and the inner wall of the conical hollow extrusion head 13 extrudes the outer surface of the elastic element 8. The surface of the front end guide tube 4 is slidably connected to the traction sleeve 15. The traction ring 12 is located in the middle of the traction sleeve 15. The surface of the traction sleeve 15 is symmetrically fixedly connected to the snap-fit ​​positioning block 16. The end of the handle part 1 near the front end guide tube 4 and located on the outer ring of the front end guide tube 4 is fixedly connected to the positioning ring 17. The snap-fit ​​positioning block 16 is snapped into the middle of the positioning ring 17.

[0036] Specifically, the reset assembly includes a fixed reset ring 14 and a reset spring 18. The fixed reset ring 14 is fixedly connected to the end of the front end guide tube 4 away from the handle part 1, and the reset spring 18 is sleeved on the surface of the front end guide tube 4.

[0037] With the above structural design, when using the device, first hold the handle 1, then align the guide head 10 with the inside of the ear canal and push it into the ear canal.

[0038] Internal movement: When the conical hollow compression head 13 moves to the front end of the inflamed area, the traction sleeve 15 is pulled to slide backward on the surface of the front catheter 4. During the sliding process, the traction sleeve 15 pulls the traction ring 12 towards the front catheter 4. At the same time, the conical hollow compression head 13 is disengaged from the surface of the elastic element 8 through the drug delivery tube 11. After the elastic element 8 stops being compressed, it deforms outward. The elastic element 8 flips outward at the same time, causing the stretchable membrane 9 to open automatically. At this time, the outside of the ear canal is isolated from the inside of the ear canal. During the movement of the traction sleeve 15, the return spring 18 is stretched. At this time, the traction sleeve 15 moves with the locking and positioning block 16 to the middle of the positioning ring 17. Rotating the traction sleeve 15 drives the locking and positioning block 16 to rotate towards the middle of the positioning ring 17 to complete the limiting of the traction sleeve 15. After the medication is applied, rotate the traction sleeve 15 to disengage the locking and positioning block 16 from the positioning ring 17. At this time, the return spring 18 pulls the traction sleeve 15 to slide on the surface of the front end guide tube 4. At the same time, the conical hollow extrusion head 13 extrudes the elastic element 8, causing the elastic element 8 to drive the telescopic soft membrane 9 to contract inward. At this time, the device can be removed from the ear and the medication can be applied.

[0039] Example 2:

[0040] The spray device for ear, nose, and throat provided in Example 1 has been further optimized, specifically, as follows: Figure 5 As shown, the jet-type drug delivery assembly 3 includes a drug storage tank 19, a sealing cap 20, a drug delivery connector 21, and a jet assembly.

[0042] With the above structural design, when the elastic element 8 drives the telescopic soft membrane 9 to unfold, the rotating sealing cover 20 opens. After the medicine is added into the medicine storage tank 19, the sealing cover 20 is screwed closed. At this time, the rubber air bladder 23 is squeezed, and the gas is delivered into the medicine storage tank 19 through the air guide tube 22. At this time, the air pressure inside the medicine storage tank 19 increases, and the gas carries the medicine powder from the medicine delivery connector tube 21 to the medicine delivery pipe 11. The medicine powder enters the ear canal through the medicine delivery pipe 11, and the medication can be administered.
