Background

In 1962, the first indwelling needle "Braun ü le" was invented by berland, germany. In the early 80 s, venous indwelling needles entered developed countries and regions in Asia, and in the 90 s, open indwelling needles entered the operating room of China first. Indwelling needle designs have gone from initially open to closed, from conventional to needlestick resistant. The open type indwelling needle is easy to cause blood leakage when withdrawing the needle core after puncture is finished, the risk of infecting blood-borne diseases of medical staff is increased, the defect is fundamentally avoided in the design, and the open type indwelling needle is an integrated design comprising an extension tube, a catheter and a closed type infusion joint (such as a heparin cap). Meanwhile, in order to avoid occupational exposure caused by needle stick injuries, the indwelling needle has been transformed into a needle stick injury prevention safety design, which allows the steel needle to be covered or wrapped by a specific device after the steel needle is withdrawn, thereby preventing medical care personnel, including medical waste disposal personnel, from being infected with blood-borne diseases due to the fact that the medical care personnel is pricked by the steel needle which is contaminated by the blood of a patient. At present, the closed indwelling needle widely applied clinically has various functions and is simple and convenient to operate, but in the link of removing the indwelling needle, nursing staff need to prepare an additional sterilized cotton swab or a cotton swab for compression hemostasis after needle removal, so that nursing workload is increased to a certain extent, meanwhile, the cotton swab packaged by plastic package has a strict service life, can not be utilized to a hundred percent, and medical cost is wasted to a certain extent.

SUMMERY OF THE UTILITY MODEL
