Liquid stopping clamp

Abstract

The invention provides a liquid stopping clamp. The liquid stopping clamp includes a body; one side of the body is provided with a fixed arm, and the other side of the body is provided with an elastic arm; the fixed arm and the elastic arm are provided with an infusion tube fixing hole each, the infusion tube fixing holes can allow an infusion tube to pass through; the body is provided with a first body locking part, a body extruding drainage part and a second body locking part; the elastic arm is correspondingly provided with a first elastic arm locking part, an elastic arm extruding drainage part, and a second elastic arm locking part; a free end of the fixed arm and a free end of the elastic arm are in a snapped condition, the first body locking part and the first elastic arm locking part, the body extruding drainage part and the elastic arm extruding drainage part, the second body locking part and the second elastic arm locking part are arranged in a pressed manner to clamp the infusion tube, in this way, liquid in the infusion tube cannot flow, infusion positive pressure can be generated, the liquid in the infusion tube can be pushed forward, it is prevented that blood flows back into the infusion tube and the blood blocks a venous indwelling needle or a needle head of an injection needle, and thrombus can be avoided.

Description

technical field [0001] The invention relates to a liquid-stopping clamp, which belongs to the technical field of medical infusion supplies. Background technique [0002] At present, intravenous infusion has the advantages of rapid administration, less irritation, and quick curative effect, and is a main treatment method in clinical medicine. The infusion set is a medical device for achieving the purpose of infusion. The infusion set is mainly composed of an upper conduit, an infusion tee, a drip funnel, a lower conduit, a flow regulator, a needle seat, a thin tube of an infusion needle, an intravenous infusion needle, and a stop clip. The upper catheter, lower catheter and thin tube of the infusion needle are collectively referred to as the infusion tube. The liquid stop clamp is clamped on the infusion tube, and the flow of the liquid in the infusion tube can be controlled by opening or closing the liquid stop clamp. However, there are still some defects in the existing co...
