Problems solved by technology

As can be seen from the above description, the existing indwelling needles require the cooperation of both hands of the medical staff during the puncture process due to the problem of structural settings. The operation is more complicated and requires higher requirements for the medical staff; The needle tip of the needle tube is exposed, which is easy to accidentally injure the contact personnel, which is very unsafe

Abstract

Disclosed is a single-hand puncture indwelling needle, comprising an indwelling needle catheter (2), a puncture needle tube (1), a needle wing (4) connected to the puncture needle tube, and a catheter seat (3) connected to the indwelling needle catheter, wherein one side of the catheter seat extends to form a side joint (32), and the needle wing is provided with a first guide surface (42a), for guiding the needle wing to drive the displacement of the puncture needle tube with respect to the side joint, and thus withdrawing from the indwelling needle catheter. The single-hand puncture indwelling needle can achieve a completely one-handed operation during puncturing, thus making the puncture operation more convenient and quick, and raising the operating efficiency of medical staff.

Description

technical field [0001] The invention relates to the technical field of indwelling needles, in particular to an indwelling needle punctured with one hand. Background technique [0002] An indwelling needle is a medical device used to give multiple infusion therapy over a period of time. The indwelling needle in the prior art mainly includes an indwelling needle catheter, a puncture needle tube, a needle wing connected to the puncture needle tube, and a catheter hub connected to the indwelling needle catheter, and the puncture needle tube connects from the other end of the catheter hub After the main joint of the indwelling needle catheter is completely penetrated, the needle tip of the puncture needle tube is just exposed outside the indwelling needle catheter, and a side joint is formed on the side wall of the catheter base, and the side joint is connected to the infusion set . After the medical personnel use the indwelling needle to puncture the blood vessel of the patien...
