Venous indwelling needle capable of preventing needle stick injury and using method of venous indwelling needle

Abstract

The invention discloses a venous indwelling needle capable of preventing needle stick injury and a using method of the venous indwelling needle, and relates to the technical field of medical instruments. The venous indwelling needle comprises a catheter base, a needle base is clamped to the bottom end of the catheter base, a telescopic rubber tube is fixedly connected to the upper surface of the needle base, the telescopic rubber tube is located in the catheter base, and the top end of the telescopic rubber tube is fixedly connected with a needle tip protection plug. According to the venous indwelling needle capable of preventing needle stick injury and the using method of the venous indwelling needle, by arranging the needle base, the telescopic rubber tube, the needle tip protection plugand a puncture needle, when medical staff guide a catheter into a blood vessel through the puncture needle, the needle base is pulled out of the catheter base through a needle handle, the needle basedrives the puncture needle to retreat from the catheter, and due to the fact that the lengthened length of the telescopic rubber tube completely stretched is equal to the length of the portion, retreating into the needle tip protection plug, of the puncture needle, after the puncture needle is pulled out, the situation that other people are accidentally injured due to misoperation is avoided, andthe risk of stick injury caused by the puncture needle is prevented.

Description

Technical field[0001]The present invention relates to the field of medical device technology, in particular a vein retaining needle that prevents needle stab and its use.Background technique[0002]The vein retaining needle is also known for the vein sleeve, the core component includes a soft conduit that can be left in the blood vessel, and the stainless steel puncture guide knocker. In the use of the catheter and the knit together into the blood vessel, when the catheter enters the blood vessel, the needle core is removed, and only the soft catheter is left in the blood vessel to perform infusion therapy. The traditional vein retaining needle, when the clinical operation is pulled out in the knot, the needle core pointed by the patient's blood may cause the medical staff to accidentally injure and infection, and the abandoned bare puncture knocked the needle causes pollution to the environment and gives medical garbage. Special treatment has caused difficulties, so there is also a s...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a venous indwelling needle capable of preventing needle stick injury and its use method, which solves the problem of the traditional venous indwelling needle, which is stuck with the patient's blood when the puncture needle core is pulled out in clinical operations. The core tip is very likely to cause accidental injury and infection of medical staff, and the discarded exposed puncture needle core pollutes the environment and makes it difficult for special treatment of medical waste. Therefore, there are also serious social hazards and hidden dangers.
