The invention discloses a novel indwelling needle capable of being conveyed into a tube automatically by one hand. The indwelling needle comprises an indwelling needle seat, a handle, a catheter and apuncture steel needle body, wherein the catheter is fixedly connected to one end of the indwelling needle seat, the handle is arranged at the other end of the indwelling needle seat, and the puncturesteel needle body is fixedly connected to the side, close to the indwelling needle seat, of the handle and penetrates through the indwelling needle seat and the catheter. The indwelling needle seat is of a cavity structure; a blocking plug is fixedly connected into a cavity of the indwelling needle seat; a stop block is fixedly connected to the side, away from a catheter, of the blocking plug; acompression spring sleeves the outer wall of the portion, between the stop block and the handle, of the puncture steel needle body; the two ends of the compression spring are in supporting contact with the handle and the stop block respectively; the handle is connected with the indwelling needle seat through a buckle. The novel indwelling needle can be conveyed into the tube automatically by one hand in a venous puncture process and avoid puncture failure caused by manual tube feeding and needle withdrawing, and the puncture success rate of the indwelling needle is increased.
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...
