[0002] The peristaltic pump for blood purification is a part frequently operated by users of blood purification equipment. The traditional peristaltic pump is fixed, so the operator must first place the pump tube in the pump during the assembly process of the pump tube, and then turn the pump wheel to make it The pump wheel presses the pump tube. Due to the structural characteristics of the peristaltic pump, the pump wheel of the peristaltic pump must be pressed against the pump tube to ensure the tightness. However, usually the force of the pump wheel pressing on the pump tube is relatively large, which leads to It requires a lot of torque when installing or removing the pump tube, and the operators of blood purification equipment are usually women, which brings great difficulties to their operation and seriously affects the operating efficiency of the equipment

The invention discloses a peristaltic pump for blood purification that automatically installs / disassembles a pump tube. A positioning sensor is installed on a motor of the peristaltic pump, and the motor of the peristaltic pump is installed on a horizontal movement mechanism. The control end of the motor is connected to the output end of the control system, the output end of the positioning sensor is connected to the input end of the control system, and the control system outputs a signal to the peristaltic pump motor, so that the pump wheel of the peristaltic pump motor stops at the position where the positioning sensor is located. The invention can make the pump wheel press the pump pipe, and in order to ensure the sealing performance, the operating efficiency of the equipment is improved at the same time.
