Theblood vessel buckling unit has a cuboid structure, the blood vessel buckle unit includes a housing, electric push rod, sliding block, power supply, controller and tube clamp, the tube clamp is arranged on one end face of the cuboid blood vessel buckle unit, the tube clamp has a semicircular structure in cross section, the tube clamp is used to clamp the blood path tube, the electric push rod is arranged at the rear side part of the tube clamp, the electric push rod is fixedly connected with the housing, the sliding block is fixedly arranged at the bottom position of the moving rod of the electric push rod, a sliding block groove is arranged between the tube clamp and the electric push rod, the electric push rod can push the sliding block to slide in the sliding block groove, the electric push rod is electrically connected with the controller, and the sliding block can seal or open the fixed blood path tube through sliding; The controller is on the opposite side of the housing from thepower supply.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a blood tube fixing clip with automatic on-off control. Background technique [0002] Hemodialysis is a common treatment method for patients with acute and chronic renal failure. This method is to draw the patient's blood out of the body through a puncture needle, central venous catheter, and blood line tube, and then reinfuse it after being dialyzed by a hemodialyzer to remove metabolic waste in the blood. into the patient's body. During this process, blood circulates in the extracorporeal blood tube and dialyzer at a rate of 200-300ml per minute, so the fixation of the blood tube is very important. If the blood line tube is not fixed firmly, it may cause the connection between the blood line tube and the puncture needle or central venous catheter to be disengaged, causing a large amount of blood to flow out of the line, causing serious consequences. At present, in the actua...
