Anti-acupuncture venous indwelling needle

Abstract

The invention relates to an anti-acupuncture venous indwelling needle. The anti-acupuncture venous indwelling needle comprises a catheter component, a needle tubing component and an infusion connector connected with the catheter component. The catheter component comprises a catheter base and a catheter. A cavity is formed in the catheter base. The needle tubing assembly comprises a needle base and a puncture needle. An anti-acupuncture component is arranged between the catheter base and the needle base and comprises a protection base internally provided with a through hole. A stop piece cavity and a lower through hole in the tail portion of the through hole are formed in the through hole. The acupuncture needle sequentially penetrates through the through hole, the cavity in the catheter base, and the catheter. A spring groove is formed in the through hole in the radial direction. A spring in the compressed state and a stop piece are arranged in the spring groove. One end of the spring abuts against the protection base, and the other end of the spring abuts against the stop piece. The stop piece can enter a cavity of the stop piece and prevent the acupuncture needle from penetrating through the through hole. The anti-acupuncture venous indwelling needle is simple in structural design, can prevent the acupuncture needle from penetrating out secondarily on the aspect of functions, effectively prevents the needle tip from puncturing medical staff, and is free of the defects of efficacy loss, deformation and blockage.

Description

technical field [0001] The invention relates to the field of infusion equipment, in particular to a needle-puncture-proof venous indwelling needle. Background technique [0002] In recent years, the scope of application of intravenous indwelling needles has been continuously expanded, and it has been widely used in clinical departments. The use of intravenous indwelling needles can reduce the pain caused by repeated venipuncture and the fear of injections, relieve the anxiety of family members, facilitate clinical medication, reduce the workload of nurses, and reduce the pain of patients. The existing venous indwelling needle is retracted after use, and the needle is contaminated by the blood of the patient. When the medical staff pulls out or cleans and discards the indwelling needle, it is easy to be stabbed by the needle and easily infected with the disease. At the same time, the discarded needle is exposed in the environment. It is easy to cause environmental pollution ...

AI Technical Summary

Problems solved by technology

[0005] There are mainly the following defects in the prior art: the telescopic structure has the risk of the steel needle passing through twice; the stainless steel shrapnel, card, and clip all rely on a certain resilience to ensure their effect, and the puncture needle is stuck, and the resistance is relatively high. Large, the sliding performance of the product is not good, and there is no guarantee that the axis can not be concentric, which loses the meaning of anti-acupuncture; in addition, these products are complex in design and difficult to assemble
