Injector needle cap preventing liquid leakage during air exhausting

Abstract

The present invention relates to the field of medical devices, in particular to a syringe needle cap for exhausting and leak-proof liquid, comprising a needle cap tube and a gas-liquid separation membrane at the bottom of the needle cap tube; the gas-liquid separation membrane is formed with the bottom of the needle cap tube closed structure. Compared with the prior art, the beneficial effect of the present invention is that the product of the present invention is composed of a needle cap tube and a gas-liquid separation membrane at the bottom of the needle cap tube, and avoids rubber on the syringe needle during use when the syringe needle is in contact with the needle cap. The risk of debris residue is safe, reliable and pollution-free in structure; the gas-liquid separation membrane is only breathable and impervious to water, during the exhaust process, only the air can be discharged, and the liquid medicine should not be discharged as much as possible, so as to reduce the waste of medicine; gas-liquid separation The membrane has very strong biological adaptability, will not cause rejection by the body, has no physiological side effects on the human body, and is safe and reliable; the invention is easy to use, can effectively reduce manpower, and improve efficiency.

AI Technical Summary

Benefits of technology

This new technology solves two technical problem areas that were previously solved during previous designs for injectors used for medical purposes such as injection into blood vessels or other organs. Firstly it avoids wasting too many liquids when inserting an IV catheter through them due to excessive pressure from being pushed against hard objects like metal buttons inside their lumen. Secondly this innovation ensures safety without causing harmful substances to healthy individuals who come near these devices. Thirdly, while maintaining its effectiveness over longer periods of usage, there're less chance they have any issues related to remaining rubble after each use. Overall, this new technology improves patient care efficiency and reduces costs associated with medications delivered via traditional methods.

Problems solved by technology

Technically speaking, this technical issue addressed by this patented technology relates to improving an efficient way of administering medication while minimizing wastage due to excessive gas being emitted from the needles used with existing devices.
