Abstract

The invention belongs to the technical field of medical apparatuses, and discloses an automatic positive pressure thrombosis-resistant venous indwelling needle. The automatic positive pressure thrombosis-resistant venous indwelling needle comprises a front tee, a rear tee and a transfusion hose, wherein the front tee communicates with the rear tee through the transfusion hose; the automatic positive pressure thrombosis-resistant venous indwelling needle further comprises a liquid stopping clip, wherein a second lug is arranged on the inner side of the liquid stopping clip; the second lug is provided with a guiding route; and the transfusion hose penetrates through the liquid stopping clip. According to the automatic positive pressure thrombosis-resistant venous indwelling needle disclosedby the invention, automatic pressurization can be realized; and through combined action of the liquid stopping clip and the transfusion hose, the effect of preventing blood return can be realized, sothat formation of thrombosis is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a self-positive pressure antithrombotic venous indwelling needle. Background technique [0002] Intravenous injections are one of the treatments people choose when they are sick, and they are usually infused through an indwelling needle. When using an intravenous indwelling needle, the catheter and the needle core are punctured into the blood vessel together. After the catheter has completely entered the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel for infusion therapy. The use of indwelling needles can facilitate clinical medication, rescue medication for acute and critically ill patients, reduce the workload of nurses, and reduce pain in patients. Therefore, intravenous indwelling needles are widely used clinically. [0003] However, during the use of existing venous indwelling needles, blood backflow often occurs d...
