Description

Remaining needle joint and remaining needle

Technical Field

The application relates to the technical field of medical instruments, in particular to an indwelling needle connector and an indwelling needle.

Background

The venous indwelling needle is also called venous trocar, and the core component parts comprise a soft catheter/cannula which can be indwelling in the blood vessel and a stainless steel puncture guiding needle core. When in use, the catheter and the needle core are punctured into a blood vessel together, after the catheter completely enters the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel so as to carry out infusion treatment. The indwelling needle can reduce the pain caused by repeated venipuncture, is convenient for clinical medication, lightens the workload of nurses, reduces the pain of patients, and is widely applied in clinic.

The venous indwelling needle is generally provided with a connector, or other better connectors such as a positive pressure connector are replaced after the puncture is successful. The connector is used for connecting an infusion apparatus for intravenous infusion. After the transfusion is finished, a 5ml syringe is used for pumping the physiological saline to seal the tube so as to prevent the blood from flowing back to block the tube and shorten the service time of the remaining needle. Because the venous indwelling needle joint is mostly cylindrical, when a nurse performs a tube sealing operation, the nurse needs to hold the indwelling needle joint with one hand and perform the tube sealing operation with the other hand, the cylindrical structure of the joint is difficult to hold and fix with fingers, and the skin of a patient is easy to hold and cause pain to the patient; meanwhile, the other hand is difficult to seal the pipe because the finger is not stable when pinching the joint.
