Separation cut-off clamp for safety vein needle

Abstract

The invention discloses a separation cut-off clamp for a safety vein needle. The separation cut-off clamp comprises a key, a barrel body and a base, wherein the key is inserted into the barrel body so as to lock an annular tooth and a barrel body limiting tooth; an arc-shaped concave groove in the base is buckled with an open groove in the lower end of the barrel body in the long axis direction and embedded with a concave groove through horizontal bumps on the side walls of the arc-shaped concave groove and the open groove; the side rope positions of a transfusion hose tube and a separation tube are buckled between the open groove in the lower end of the barrel body and the arc-shaped concave groove in the base; the key is rotated for 90 degrees and pressed down, so that a pressing plate is moved down to be in interact with a recess in the base so as to squeeze and block the separation tube; and meanwhile, the transfusion hose tube is closed by an arc-shaped groove in the bottom surface of the pressing plate and the arc-shaped groove in the base. Under the action of an external spring force, the vein puncture needle quickly departs from a blood vessel and retracts into a protection sleeve tube for shielding protection. According to the separation cut-off clamp, the cut-off effect of the protection of the vein puncture needle on the transfusion hose tube can be finished by one hand under one action; and the separation cut-off clamp has a safety structure and the characteristics of simplicity and practicality, safety and reliability, high efficiency and less pain.

Description

(1) Technical field [0001] The invention relates to a medical device, in particular to a cut-off clip used for safety protection of a venipuncture needle. (2) Background technology [0002] Collect, analyze and test the substances in the veins to obtain the physiological or pathological state of the human body, or puncture the veins, infuse the medicinal liquid into the veins to reach the whole body, play, compensate, replace and treat; in the above tests and treatments The process requires a venipuncture needle to achieve damage to the human veins and blood vessels, so as to establish a temporary channel from the outside to the blood vessels. [0003] At present, various venipuncture needles (infusion needles, blood transfusion needles, blood collection needles, biopsy needles, indwelling needles, etc.) After the venipuncture needle is used in the above environment, the needle tip of the venipuncture needle is exposed outside, and the needle tip that contacts the patient's...
