Endoscopic outer sleeve airbag with double hoses

Abstract

The invention discloses an endoscopic outer sleeve airbag with double hoses.. The endoscopic outer sleeve airbag comprises a flexible airbag, a water spray hose and an inflating hose, wherein the middle part of the flexible airbag is hollow, and the outer part of the flexible airbag is tubular; the hollow part of the airbag is sleeved on an endoscope body, one end of the airbag is hermetically and fixedly connected with the inflating hose, and an outer sleeve is sleeved on the outer part of the inflating hose; the water spray hose is arranged in the outer sleeve; and the water spray hose penetrates through the airbag and extends out of the other end of the airbag, the other end of the water spray hose extends out of the outer sleeve and is connected with an injector interface, and the other end of the inflating hose extends out of the outer sleeve and is connected with the air inlet interface of a gas control valve through an inflating interface. The airbag is small in size; only one tiny part of the outside diameter of the endoscope is added, and additional pain is not produced for a patient due to insertion of the endoscope; and the airbag effectively improves the treatment effect.. The airbag is low in manufacturing cost, can be used as a disposable product to prevent cross infection, has high social benefits, and furthest meets the operation requirement of the patient.

Description

technical field [0001] The invention relates to an accessory of a medical endoscope, in particular to an endoscope coat air bag with double tubes. Background technique [0002] Since China is the hardest-hit area of ​​infectious hepatitis epidemic, according to statistics, about 10% of the people in China are infected with hepatitis B, plus other liver diseases such as alcoholic liver and fatty liver. Some of them will eventually develop into cirrhosis of the liver. Esophageal varices are one of the main complications of liver cirrhosis. Rupture and bleeding of esophageal varices can cause 25% to 50% mortality. Endoscopic injection of sclerotherapy is the first choice for the treatment and prevention of bleeding from esophageal varices. Its functions: (1) thicken the vein wall; (2) thrombosis in the vein; (3) coagulation and necrosis of the mucous membrane around the vein to form fibrosis, strengthen the covering layer of the vein, and prevent varicose veins from rupture ...

AI Technical Summary

Problems solved by technology

This gastroscope accessory has a certain function of preventing ectopic embolism and air bag compression to stop bleeding. However, due to its large size and thick outer diameter of the cannula, when it is inserted with the gastroscope, the patient suffers a lot and may cause bleeding.

And the production is complicated and the cost is high. If it is disposable, the waste will be large and the medical expenses will be increased.

In addition, the "gastroscope outer tube" is not equipped with a special mouth pad. During the process of inserting into the mouth, the patient is likely to bite the outer tube and damage the gastroscope. Moreover, it is not convenient for the front end of the gastroscope to move, and the angle of the injection needle cannot be adjusted, which affects the injection effect.

It cannot be treated, and it is difficult to adapt to the needs of gastroscopic surgery, and it is difficult to promote in actual use
