specific Embodiment

[0021] refer to Figure 1-3 , a new type of venipuncture needle with a guide wire, including an indwelling tube 2, and two side ports 3 are opened on one side wall of the indwelling tube 2, and the side ports 3 extend to the inner wall of one side of the puncture needle 4, and the indwelling tube 2 When the main opening sticks to the blood vessel wall, it is helpful to complete the infusion. One end of the indwelling tube 2 is conical, and one end of the guide wire 1 is conical. The guide wire 1 is inserted into the indwelling tube 2 and against the inner wall of one side A puncture needle 4 is inserted into the inner wall of one side of the indwelling tube 2, and the inner wall of one side of the indwelling tube 2 is fixedly connected with the side wall of the puncture needle 4, and a guide wire 1 is inserted in the puncture needle 4, and the guide wire 1 adopts transparent Made of soft polyvinyl chloride plastic injection molding and cutting, one side wall of the guide wire ...

Abstract

The invention provides a novel venipuncture needle with a guide wire, which relates to the technical field of medical supplies and includes an indwelling tube. A puncture needle is inserted into one side of the indwelling tube. The connection is fixed, and a guide wire is inserted in the puncture needle. The venipuncture needle with guide wire can improve the success rate of venous catheterization, reduce the restriction of catheter placement caused by plaque and blood vessel bending, and help confirm the position of the guide wire in the vein by showing the blood outflow. Exact insertion and design of the indwelling tube can reduce the obstruction of intravenous infusion caused by body position factors; the side port of the indwelling tube can continue to realize the intravenous infusion process when the main channel of the indwelling tube is blocked, no matter for intravenous infusion and pressure measurement. Provide assistance, improve medical efficiency, reduce the waste of medical materials, and provide great help for the stable realization of medical safety.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a novel venipuncture needle with a guide wire. Background technique [0002] When people prevent and treat diseases, they usually need to puncture the veins to collect, analyze and test the substances in the veins to obtain the physiological or pathological state of the human body; The whole body plays, compensates, replaces and treats; in the above inspection and treatment process, a venipuncture needle is needed to realize the intervention of human veins with damage, so as to establish a temporary channel from the outside to the inside of the blood vessel. [0003] However, most of the existing puncture needles have a high puncture failure rate during use, and the infusion tube and the inner wall of the blood vessel affect the infusion, etc., which need to be improved. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomin...
