Environment-friendly disposable dead-corner-free anti-puncture indwelling needle

Abstract

The invention discloses an environment-friendly disposable dead-corner-free anti-stabbing remaining needle. Comprising an indwelling catheter and a puncture assembly. The indwelling catheter comprises a needle tube and an indwelling needle sleeve, and a puncture needle core inserting opening and an infusion leading-in opening are formed in one end of the indwelling needle sleeve; the puncture assembly comprises a puncture needle head and a protection piece, a first via hole is formed in the protection piece, the periphery of the protection piece extends outwards to form at least four opposite claw parts, clamping force close to the center exists in three claw parts, an extending end is arranged at the tail end of the other claw part, and the first via hole is communicated with the extending end. The extending end is provided with a second via hole right opposite to the first via hole, the hole wall of the second via hole abuts against the outer wall of the puncture needle head, and the tip end of the puncture needle head is provided with a groove used for forming a clamping structure with the claw part when the puncture needle head is pulled out. According to the embodiment, wrapping type protection can be effectively achieved through the protection piece, and secondary cross infection caused by the puncture needle head is avoided.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an environment-friendly disposable indwelling needle with no dead angle and anti-stab injury. Background technique [0002] As we all know, the indwelling needle is actually an auxiliary infusion device that replaces the traditional disposable infusion needle. Its purpose is to reduce the pain of repeated puncture of patients and the nursing workload of medical staff. It has been widely used clinically. As for the overall structure of the indwelling needle, it generally consists of an indwelling catheter and a puncture assembly arranged in the indwelling catheter. The patient is given a continuous infusion of the drug solution. [0003] However, since the puncture components are used sequentially, in order to avoid needle stabbing people in the process of garbage disposal or recycling, resulting in secondary cross-infection, the existing intravenous infusion needles w...

Problems solved by technology

Although this kind of safety protection sleeve can prevent others from being stabbed by the needle in the future, when the needle and the safety protection sleeve are paired, it will also bring the risk of stabbing, and further increase the workload of medical staff and the need to withdraw from the puncture. Accidentally injure medical staff during assembly, accidentally injure staff when recycling medical waste, cause disease spread and increase medical expenses due to accidental injury, the overall use is not convenient enough, the steps of recycling medical waste into raw materials increase and the risk of accidental injury increases
