Ear-hook nasal administration device capable of preventing inverse suction and administration method

Abstract

The invention discloses an ear-hook nasal administration device capable of preventing inverse suction and an administration method. The ear-hook nasal administration device comprises an ear hook and amedicine cavity connected to the ear hook, wherein the medicine cavity is connected with an administration head through a PE hose, a mini air pump is arranged on a side wall of the medicine cavity, and an exhaust port of the mini air pump communicates with an inner cavity of the medicine cavity; and the administration head is of a hollow conical structure, an end surface, away from the PE hose, of the administration head is a spherical surface, an administration opening penetrating through the side wall is formed in the side wall of the administration head, a check valve for limiting a liquidmedicine from flowing from inside of the administration head to outside unidirectionally is arranged in the administration port, and a sponge layer is arranged on the outer surface of the administration head. According to the ear-hook nasal administration device capable of preventing inverse suction and the administration method, constant-speed administration for nasal cavity can be realized, inverse suction of the administration head can be effectively prevented, and the condition of contamination of the liquid medicine in the medicine cavity due to inhalation of nasal secretions is avoided.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to an anti-sucking ear-hook nasal cavity drug delivery device and a drug delivery method. Background technique [0002] Conventional nasal surgery often requires follow-up hemostasis, analgesia and other treatment and care. Generally, analgesic methods that directly administer drugs to the nasal cavity are used, such as thin tube drop method and spraying method. Whether the drug tube enters the patient's nasal cavity and directly injects it into the affected area, or uses an atomization device for spray administration, both require medical staff to continue administering the drug manually, which cannot achieve continuous and uniform drug administration, and wastes a lot of manpower time. In view of this situation, continuous drug administration can be achieved by setting a micro-air pump to provide continuous slight positive pressure. However, when the micro-air pump stops working ...

[0002] Conventional nasal surgery often requires follow-up hemostasis, analgesia and other treatment and care. Generally, analgesic methods that directly administer drugs to the nasal cavity are used, such as thin tube drop method and spray method. Whether the drug tube enters the patient's nasal cavity and directly injects it into the affected area, or uses an atomization device for spray administration, both require medical staff to continue to administer the drug manually, which cannot achieve continuous and uniform drug administration, wasting a lot of manpower time

In view of this situation, continuous drug administration can be achieved by setting a micro-air pump to provide continuous slight positive pressure. However, when the micro-air pump stops working and there is a temperature change in the drug cavity, which leads to a negative pressure in the drug cavity, the method adopted in this way The dosing head is prone to sucking back, which will cause the patient's nasal secretions to be sucked back into the medicine cavity, pollute the medicine liquid in the medicine cavity, and affect further use
