Puncture needle fixing device of infusion set

Abstract

The invention relates to the technical field of auxiliary devices of medical instruments, and in particular to a puncture needle fixing device of an infusion set. The puncture needle fixing device isadditionally provided with a fixing mechanism to reinforce a puncture needle of the infusion set in an infusion bottle, so that the probability that the puncture needle of the infusion set is pulled away in the infusion set carelessly due to human factors is reduced; therefore, the risk that pollutants enter human blood is reduced, and the use safety of the infusion set is improved; and meanwhile,the probability of replacing the infusion set is reduced, and infusion cost is reduced. The puncture needle fixing device comprises a body of the puncture needle of the infusion set; a fixing ring isarranged at the bottom area of the body of the puncture needle of the infusion set; the puncture needle fixing device also comprises a reinforcing frame, two groups of fixing rods, a mounting plate,a rotating shaft, an extrusion rod, an elastic clamping rod and a clamping block; the middle part of the top end of the lower right region of the reinforcing frame is provided with a sliding-in U-shaped groove in a penetrating way; the bottom area of the body of the puncture needle of the infusion set is slidably clamped with the sliding-in U-shaped groove; and the front side of the right end of the mounting plate is provided with a mounting groove.

Description

technical field [0001] The invention relates to the technical field of medical device attachments, in particular to a puncture needle fixing device for an infusion set. Background technique [0002] As we all know, in the process of clinical infusion treatment, medical staff will insert the puncture needle into the infusion bottle through the infusion set, so that the medicinal liquid flows into the patient's body through the infusion set; however, in the process of using the existing infusion set, due to artificial Due to factors, the puncture needle of the infusion set may be pulled vigorously. At this time, the puncture needle of the infusion set has a high probability of slipping in the infusion set, thus increasing the risk of pollutants entering the human blood. At the same time, due to the need to replace the infusion set Then the transfusion cost has been improved. Contents of the invention [0003] In order to solve the above technical problems, the present inven...
