Venous indwelling needle capable of preventing blood from outflowing

Abstract

The invention belongs to the technical field of medical treatment and discloses a venous indwelling needle capable of preventing blood from outflowing. The venous indwelling needle capable of preventing the blood from outflowing comprises a tube which is in clamping connection with an arc clamping part, a connecting piece is fixedly connected to one side, far away from the tube, of the arc clamping part, an adhesive tape is arranged on one side, far away from the arc clamping part, of the connecting piece and consists of a non-woven fabric layer, an adhesive layer and release paper, the adhesive layer is arranged on one side, far away from the connecting piece, of the non-woven fabric layer, the release layer is arranged on one side, far away from the non-woven fabric layer, of the adhesive layer, a handle is arranged on one side of the tube, and a spacer plug is arranged in the tube. The venous indwelling needle capable of preventing the blood from outflowing has the advantages that the connecting piece is clamped on one side of the tube through the arc clamping part, the adhesive tape is arranged on one side, far away from the arc clamping part, of the connecting piece, and the tube can fit a hand back of a child patient, so that a needle tube can be prevented from slipping during infusion and damaging the blood vessel wall of the child patient; the middle of the adhesive tape is low in adhesiveness while two sides thereof are strong in adhesiveness, so that the needle tube can be extracted conveniently when infusion is completed.

Description

technical field [0001] The invention belongs to the field of medical technology, and particularly relates to a venous indwelling needle capable of preventing blood outflow. Background technique [0002] Indwelling needle injection medical device, the core components include a soft catheter / cannula that can be indwelled in the blood vessel, and a stainless steel puncture guide needle core. When in use, the catheter and the needle core are punctured into the blood vessel together. When the catheter is fully inserted After the blood vessel, the needle core is withdrawn, and only the soft catheter is indwelled in the blood vessel for infusion therapy. The use of the indwelling needle can reduce the pain caused by repeated venipuncture and the fear of injection, and reduce the anxiety of parents. Emotions are convenient for clinical medication, rescue medication for acute and critically ill children, reduce the workload of nurses, and reduce pain in children. Therefore, intraveno...

Problems solved by technology

[0004] 1. This method of fixing the needle tube and the tube body is not strong enough to fit the tube body to the skin of the child. At the same time, the existing indwelling needle often uses a small clip to clamp the extension tube to prevent blood backflow;

[0005] 2. This small clip is easy to loose and has a large volume, which is not easy to use. Therefore, we propose a venous indwelling needle with a blood draw port that can stop blood outflow to solve the above problems
