Cork puncture device for easy entry gas

Abstract

The invention discloses a cork puncture device for easy entry gas. The puncture device comprises a puncture needle, a needle tip is integrally formed at one end of the puncture needle, a liquid flow channel is arranged in the interior of the puncture needle, a gas flow channel is arranged in the interior side of the puncture needle far away from the liquid flow channel, a gas inlet port is integrally formed at the middle side of the puncture needle, the gas inlet port communicates with the end of the gas flow channel, the inner part of the gas inlet port is clamped with a gas inlet plug, a gasinlet hole is arranged in the middle of the gas inlet plug, the interior of the gas inlet hole is clamped with a blockage, a turnover plate is integrally formed at one side of the blockage far away from the gas inlet plug, and the turnover plate is movably connected with the gas inlet plug. According to the present invention, the problem of infusion interruption caused by the blockage of the gasflow channel of the cork puncture device is solved, the replacement of infusion apparatus due to the blockage of the cork puncture device is avoided, the medical treatment cost of patients is reduced,the workload of medical staff is reduced, and the puncture device has simple structure, convenient clinical operation and low production cost, and can be widely applied in clinical.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an easy-air bottle stopper piercer. Background technique [0002] Disposable infusion sets are mainly used for intravenous infusion of medical solutions for injured patients. The cork piercer is an important part of the infusion set. In the existing clinical infusion treatment process, there are three common types of cork piercers for puncturing infusion containers. Types: steel needle cork piercer, plastic cork piercer and plastic steel needle cork piercer. [0003] Since the air intake chamber of the cork piercer is equipped with an air filter membrane that prevents the entry of dust and bacteria in the air, it often occurs that the intake channel is blocked due to the air filter membrane, which will cause The infusion container produces negative pressure due to the inability to replenish air, which leads to the serious consequences of interruption of the infusion proc...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of easy-intake bottle cork piercer, to solve the above-mentioned background technology, because the air filter membrane that prevents dust and bacteria in the air from entering is installed in the air inlet passage of the bottle cork piercer Therefore, it often occurs that the air intake channel is blocked due to the air filter membrane, which will cause negative pressure in the infusion container due to the inability to replenish air, which will cause serious consequences for the patient to interrupt the infusion process. Due to the interruption of the infusion, the The blood backflow of the patient's venous system enters the pipeline of the infusion set, causing the patient's panic and seriously threatening the patient's life.
