Abstract

The invention belongs to the technical field of medical instruments, and provides a nursing indwelling needle capable of avoiding medical infection and a using method of the nursing indwelling needle. The indwelling needle comprises a supporting barrel, a puncture needle core and a liquid injection connector assembly, wherein the non-prickling end of the puncture needle core extends into the supporting barrel and is connected with a displacement adjusting assembly in the supporting barrel; and the prickling end of the puncture needle core sequentially penetrates through a sealing piece and a liquid cavity and then extends into a catheter. According to the indwelling needle provided by an embodiment of the invention, firstly, the prickling end of the puncture needle core is rapidly stored in the catheter through the restoring force of a supporting spring, and then the puncture needle core is completely pulled out and stored through the displacement adjusting assembly; and thus, the problem that the puncture needle core cannot be completely stored due to insufficient stroke caused by a spring of a single structure can be avoided, and the problem that the risk of further exposure of the puncture needle core due to the fact that the puncture needle core cannot be completely pulled out and stored is also effectively solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a nursing indwelling needle for avoiding medical infection and a use method thereof. Background technique [0002] The intravenous indwelling needle can reduce the pain caused by repeated punctures, protect blood vessels, facilitate clinical medication and emergency rescue, and reduce the workload of nursing staff. [0003] At present, intravenous indwelling needles are also called venous trocars. The core components include soft catheters that can be placed in blood vessels, and stainless steel puncture guide cores. When in use, the catheter and the needle core are punctured into the blood vessel together. After the catheter has completely entered the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel for infusion therapy. [0004] For traditional intravenous indwelling needles, when the puncture needle core is...
