Description

Remaining needle with heparin cap support

Technical Field

The application relates to the field of infusion medical equipment, in particular to an indwelling needle with a heparin cap support.

Background

The venous indwelling needle is a medical device applied to venous transfusion treatment. The use of the indwelling needle can reduce the pain of the patient caused by repeated venipuncture and reduce the workload of nurses. The core component of the indwelling needle comprises a soft catheter capable of indwelling in a blood vessel and a stainless 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are punctured into a blood vessel together, after the catheter completely enters the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel so as to carry out infusion treatment.

An invention patent with publication number CN102641529A discloses an indwelling needle. The remaining needle comprises a needle head component and a liquid injection joint component. The needle head component and the liquid injection joint component are connected through a conduit. The needle head component comprises a cannula seat and a puncture needle arranged in the cannula seat, a catheter is sleeved outside the puncture needle, and the tail part of the puncture needle is connected with a handheld part. The liquid injection joint component comprises a heparin cap and an end cap. When the puncture needle is used, the puncture needle and the catheter are punctured into a blood vessel, after the catheter completely enters the blood vessel, the puncture needle is withdrawn by moving the handheld part, only the catheter is left in the blood vessel, and the needle head of the syringe is connected with the heparin cap, so that intravenous injection and transfusion are realized.

Aiming at the related technologies, the heparin caps for sealing the indwelling needle in clinical use are cylindrical and easy to roll, and a plurality of methods are adopted to fix the heparin caps clinically, and most of the methods adopt adhesive tapes to fix the heparin caps. The use of adhesive plaster for fixation can cause a certain pressure on the skin by the heparin cap, and after a long time, the heparin cap can cause indentation and even pressure sore to a patient, thereby causing pain. Clinically, high-lift platform fixation is required to reduce the pressure of the heparin cap on the skin. The high platform lifting method is to stick the middle position of the adhesive tape to the center of the heparin cap, wrap the heparin cap by 360 degrees and then make the heparin cap higher than the skin, and stick the adhesive tapes on the two sides to the skin on the two sides. The inventors believe that the use of a high-lift platform method to immobilize the heparin cap is time consuming and laborious.
