Abstract

The invention provides an anti-puncture remaining needle assembly and belongs to the field of medical apparatus and instruments. The assembly comprises a puncture assembly, a hose holder, a hose and an anti-puncture assembly; a bulge with outer diameter larger than that of a steel needle is formed on the steel needle, and a notch is formed in the side edge of the hose holder; an elastic piece baseis a tubular base provided with an opening in the bottom, an elastic piece groove in the side part and an elastic piece baffle at the top, a partition is fixedly mounted in a sleeve, and steel needlepassing holes with outer diameter larger than outer diameter of the bulge are formed in the elastic piece baffle and the partition; a propping piece propped against the outer wall of the steel needleis fixed on an anti-puncture elastic piece, and the steel needle is enabled to lean against the inner side of the anti-puncture elastic piece; the elastic piece base is sleeved with the sleeve, and the anti-puncture elastic piece is mounted in the elastic piece groove and the sleeve; the elastic piece base is inserted into the hose holder, and the anti-puncture elastic piece bulges out of the elastic piece groove and is clamped at the notch in a hanging manner. The anti-puncture remaining needle assembly which can be used for storing and protecting the steel needle during needle withdrawal issimple in structure, convenient to mount and good in anti-puncture effect.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anti-needle indwelling needle assembly. Background technique [0002] With the improvement of people's living standards, indwelling needles with less damage to blood vessels have been widely used clinically. However, during the infusion operation, the steel needle needs to be pulled out from the hose and disposed of properly after the puncture. This process may stab the medical staff, causing injury or even cross-infection of the medical staff, endangering their health and safety. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-acupuncture indwelling needle assembly capable of storing and protecting the steel needle when the needle is pulled out, which has the advantages of simple structure, convenient installation and good anti-stab effect. [0004] The technical problem to be solved by the present inventio...
