Abstract

The invention discloses a novel remaining needle with a function of automatically conveying a catheter by single hand. The novel remaining needle comprises a remaining needle seat, a grab handle, a catheter and a puncture steel needle, wherein the catheter is fixedly connected to one end of the remaining needle seat, the other end of the remaining needle seat is provided with the grab handle, theside, close to the remaining needle seat, of the grab handle is fixedly connected with the puncture steel needle, and the puncture steel needle penetrates through the remaining needle seat and the inner portion of the catheter; the remaining needle seat is of a cavity structure, the cavity of the remaining needle seat is internally and fixedly connected with a blocking plug, the side, away from the catheter, of the blocking plug is fixedly connected with a stop block, the outer wall of the puncture steel needle between the stop block and the grab handle is sleeved with a compression spring, and the two ends of the compression spring are in support contact with the grab handle and the stop block respectively; the grab handle is connected with the remaining needle seat through a buckle. Thenovel remaining needle can achieve automatic catheter conveying by the single hand during venous puncture, solves the problem of puncture failure caused by manual catheter conveying and needle withdrawing, and increases the puncture success rate of the remaining needle.

Description

technical field [0001] The invention discloses a medical instrument for venous treatment, in particular to a novel indwelling needle which can automatically send a tube with one hand during venipuncture. Background technique [0002] Intravenous infusion is an important way of administering drugs for clinical treatment. According to public data, the annual infusion in China exceeds 10 billion bottles. With the implementation of "zero tolerance for steel needles", indwelling needles have become the main tool for clinical infusion therapy. They have the advantages of not easily damaging blood vessels and reducing the number of venipunctures for patients. The work efficiency of nurses has also been improved. In clinical nursing work, the existing indwelling needle puncture mostly adopts two-handed method. During the operation, the left hand tightens the skin, the right hand holds the needle for puncture, and then fixes the needle wing with the right hand, and the left hand hol...
