Description

Subcutaneous gas discharge device

Technical Field

The utility model relates to a subcutaneous gas discharging device.

Background

Clinically, some patients, such as pneumothorax patients, have partial gas entering subcutaneous tissues, and the patients with slight symptoms can recover through natural absorption, while the patients with severe symptoms can cause edema, and then the subcutaneous gas needs to be discharged.

In the prior art, no special device for subcutaneous gas exhaust is available, needle poking exhaust is frequently adopted clinically, and needle tools generally adopt a soft intravenous retention needle or a hard needle of a 50ml syringe, and the main problems of the needle tools comprise:

(1) without a proper puncture needle, the puncture needle of the indwelling needle tool is thinner, the formed exhaust channel is small, the exhaust is inconvenient, the hard needle of the 50ml needle cylinder is very thick, and subcutaneous tissues can be damaged.

(2) Subcutaneous gas has no obvious pressure difference compared with external air pressure, is difficult to exhaust naturally, often needs medical personnel to extrude the periphery to exhaust, and occupies the working time of the medical personnel.

(3) Subcutaneous puncture is different from venipuncture, and blood backflow can be observed after venipuncture is successful to judge whether puncture is successful or not.

(4) The gas may continue to enter the subcutaneous space and the wound passage formed by the existing needle stick will heal by itself, which also means that if the gas continues to enter the subcutaneous space, repeated punctures are required for degassing.
