Description

An improved indwelling needle

technical field

The invention relates to the field of medical infusion devices, in particular to an improved indwelling needle.

Background technique

The use of indwelling needles can reduce the pain and fear of injections caused by repeated venipuncture in children, reduce the anxiety of parents, facilitate clinical medication, rescue medication for emergency and critically ill patients, reduce the workload of nurses, and reduce the number of children. Because of the pain, intravenous indwelling needles are widely used in clinic. In the face of this special group of children, the length of indwelling intravenous indwelling needles and the comfort of children have become the most concerned issues for nurses and parents, and it is also a sign and promotion of the successful use of indwelling needles. On the premise, the design of the indwelling needle has experienced from the initial open type to the closed type, from the ordinary type to the needle-stick safety type. The open type indwelling needle is the earliest form of indwelling needle. As the name suggests, the end of the catheter hub is open, Therefore, when the needle core is withdrawn at the end of the puncture, it is easy to cause blood leakage, which increases the risk of medical staff contracting blood-borne diseases. Even if gloves are used, this risk still exists; and the design of closed indwelling needles is fundamentally avoided. To overcome this drawback, it is an integrated design that includes an extension tube, a catheter and a closed infusion connector. Because the indwelling needle is often used by young patients, the fixation of the indwelling needle is also very important. The existing way is to use multiple tapes Fixing, this will not only increase the discomfort of the patient, but also the tape is easy to lose its stickiness and fall off. In view of this situation, an improved indwelling needle is now proposed.
