Abstract

A safe indwelling needle, comprising: a puncture needle body (1) and a shielding cap (3); the shielding cap (3) is provided with a first cavity (33）, and a first through hole (32) and a second through hole (34) axially and correspondingly disposed at the two ends of the outer wall of the shield cap (3); the first through hole (32) and the second through hole (34) communicate with the first cavity （33）; the puncture needle body (1) comprises a needle tube (13) and a needle tip (11); a side hole (12) is provided on the needle tip (11); the needle tip (11) and the needle tube (13) are provided with a through cavity; a stepped surface is provided at the joint of the needle tip (11) and the needle tube (13); the stepped surface forms a limit portion preventing the needle tip (11) from sliding out of the shield cap (3); the space between the first through hole (32) and the second through hole (34) is greater than the distance between the limit portion and the apex of the needle tip (11). The safe indwelling needle provides a needle-tip shielding effect, thus avoiding accidental puncture caused by an exposed needle tip.

Description

Technical field [0001] The invention relates to the technical field of medical needles, in particular to a safety type indwelling needle. Background technique [0002] An indwelling needle is a medical device used for multiple infusion treatments within a certain period of time. It generally includes a puncture needle and an indwelling catheter sheathed on the puncture needle. Since the indwelling catheter is soft and elastic, when the catheter is indwelled in a blood vessel, the catheter will bend and twist synchronously with the blood vessel, so that the indwelling part of the catheter can still move freely without the risk of puncturing the vein. Therefore, compared with ordinary scalp needles, the use of indwelling needles for infusion is safer and reduces the discomfort of patients during infusion. [0003] The use of the indwelling needle also brings the risk of accidentally stabbing the medical staff with the exposed needle tip after the indwelling needle is punctured. In t...
