[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 ...

The invention provides a novel venipuncture needle with a guide wire, and relates to the technical field of medical supplies. The novel venipuncture needle comprises an indwelling tube, wherein a puncture needle is inserted and arranged in the inner wall of one side of the indwelling tube; the inner wall of one side of the indwelling tube is fixedly connected with the side wall of one side of thepuncture needle; and the guide wire is inserted and arranged in the puncture needle. According to the venipuncture needle with the guide wire, the success rate of vein catheterization can be improved;the situation of catheterization limitation due to plaque and blood vessel bending is reduced; the blood outflow condition is shown in real time to help confirm accurate placement of the guide wire in a vein; through the design of the indwelling tube, intravenous infusion obstruction caused by body position factors can be reduced; and through a side opening of the indwelling tube, the intravenousinfusion process can be continuously realized when a main access of the indwelling tube is obstructed. Help is provided for intravenous infusion and pressure measurement; the medical efficiency is improved; the waste of medical materials is reduced; and great help is provided for 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...
