Air-passing type medical-use blood-stop plug for postnaris

Abstract

A breather-type medical plug for treating nasal hemorrhage by filling it in rear naris is composed of a conic filling air bag, a pressure indicating air bag with aerating valve, an aerating tube connected between said two air bags, an air tube passing through said conic air bag, a tracting and fixing thread close to said conic air bag, and a thread clamping and fixing rod. Its application is also disclosed.

Description

technical field [0001] The invention belongs to medical instruments, in particular to a posterior nostril hemostatic packing device. Background technique [0002] Posterior nostril bleeding is one of the common clinical emergencies in otolaryngology. It is often violent and requires rapid and effective hemostasis measures. At present, the posterior nostril gauze ball packing method is often used, but the operation method is relatively complicated. The gauze ball needs to be pulled with a guide tube before reaching the posterior nostril. Due to the limitation of the recipient position, a half-sitting position is required, and there are requirements for lighting. And the yarn ball size is more difficult to grasp. Chinese Patent Publication No. CN99223137.X discloses a nasal cavity hemostatic air bag, which consists of four parts: nasal obstruction, nasal cavity air bag, airway tube, and backguy. The front and back of the airbag can only be expanded into one plane, and cannot...

AI Technical Summary

Problems solved by technology

This hemostatic airbag achieves the hemostatic effect to a certain extent, but because the structure of the nasal cavity and posterior nostril airway varies from person to person, it cannot meet the needs of different patients in actual application, and the patient's breathing will be affected after use, and the airbag cannot be judged Deep into the nostrils, it is not easy to find the displacement of the compression position

In addition, the pressure of the airbag cannot be judged. If the pressure is too high, it will cause pain to the patient. If the pressure is too small, the hemostatic effect cannot be achieved, which is very inconvenient to use
