Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a nasal medication device. Background Art

[0002] Patients often use nasal drops to treat rhinitis. When using them, the patient lies on his back, inserts the nozzle of the nasal drops into the nostrils, and then squeezes the nasal drop bottle to drip the medicine into the nostrils through the nozzle. However, when using them, the medicine tends to flow out of the nostrils, resulting in ineffective drug administration. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a nasal drug delivery device that can prevent liquid medicine from flowing out of the nostrils and ensure effective drug delivery.

[0004] The technical solution adopted by the utility model is as follows: a nasal drug delivery device, comprising a drug delivery piece, the drug delivery piece comprising a conical adapter tube, the side wall of one end of the adapter tube can be fitted with the inner wall of the front end of the nostril, and the other end can be located in the nostril, the end of the adapter tube located in the nostril is surrounded by a plurality of petal-shaped connecting pieces, one end of the adapter tube is fitted with the inner wall of the front end of the nostril, the dropper on the nasal drops passes through the adapter tube to open the connecting piece and is located in the nostril, and the connecting piece, the adapter tube, the dropper and the nostril cooperate to close the front end of the nostril.

[0005] Principle of the technical solution:

[0006] One end of the adapter tube extends into the nostril, and the other end fits with the inner wall of the front end of the nostril. Since the end of the adapter tube located in the nostril is surrounded by multiple petal-shaped connecting pieces, the nozzle on the nasal drop passes through the adapter tube to open the connecting piece to open outward and is located in the nostril. The end of the connecting piece close to the front end of the nostril fits with the side wall of the nozzle. At this time, the end of the adapter tube away from the connecting piece fits with the inner wall of the front end of the nostril. That is, the inner wall of the nostril, the adapter tube, the connecting piece and the nozzle cooperate to close the front end of the nostril. Then, the nasal drop is held in the hand and the bottle of nasal drop is squeezed. The medicine enters the nostril through the nozzle. At this time, the front end of the nostril is closed, and the squeezed medicine is always in the nostril.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] The adapter tube of the utility model can be connected to the nostrils, and the connecting piece on the adapter tube can allow the drip nozzle to pass through and can fit with the side wall of the drip nozzle. The adapter tube, the connecting piece and the drip nozzle cooperate to ensure that the front end of the patient's nostrils is closed, prevent the medicine from flowing out of the nostrils, and ensure effective drug administration.

[0009] As a preferred embodiment of the present utility model, an annular support portion for supporting the dropper is provided at one end of the adapter tube away from the connecting piece. The support portion is located at the nostril and the philtrum, and the longitudinal section of the support portion is arched.

[0010] Advantageous effects: The support portion can provide support for the dropper, preventing the dropper from shaking left and right after extending into the nostril and poking the inner wall of the nostril.

[0011] As a preferred embodiment of the present utility model, the support portion has elasticity.

[0012] Advantageous effects: Since there are slight differences in the sizes of the droppers on different nasal drops, for example, some droppers have larger radial dimensions, which can improve adaptability.

[0013] As a preferred embodiment of the present utility model, an adhesive portion that can fit with the nasal alae and the philtrum is provided at one end of the support portion away from the connecting piece.

[0014] Advantageous effects: It can enhance the connection strength between the adapter tube and the nose.

[0015] As a preferred embodiment of the present utility model, the longitudinal section of one end of the adapter tube located in the nostril is arc-shaped.

[0016] As a preferred embodiment of the present utility model, the adapter tube is made of rubber material.

[0017] Advantageous effects: The rubber material is both soft and elastic, and has a certain strength, which can adapt to nostrils of different shapes. Description of the Drawings
