Embodiment Construction
[0033] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, so as to make the technical solution and beneficial effects of the present invention clearer. It can be understood that the drawings are only for reference and description, and are not used to limit the present invention. The dimensions shown in the drawings are only for the convenience of clear description, and do not limit the proportional relationship.
[0034] figure 1 A schematic structural diagram of main basic components of a portable dialysis device 300 according to an embodiment of the present invention is shown. The portable dialysis device 300 includes a peristaltic pump 200 and a dialyzer 301 . The peristaltic pump 200 is typically a peristaltic pump or a tube-roller pump. The peristaltic pump 200 pumps the arterial blood of the user, monitors, dialysis and transports the arterial blood through other paths of the portable dialysis...

The invention relates to the technical field of electromechanics, and provides a peristaltic pump and portable dialysis equipment with the peristaltic pump. The peristaltic pump comprises a motor, a rotating shaft connected with the motor and used for outputting motor torque, a pump head, a rotor contained in a pump cavity of the pump head and a pipe portion arranged adjacent to the rotor, the rotor is rotatably supported in the pump cavity through the rotating shaft, and the rotor is detachably locked on the rotating shaft through a locking device. The locking device comprises an elastic piece used for axially locking the rotor relative to the rotating shaft and a buckling piece used for circumferentially locking the rotor relative to the rotating shaft, the buckling piece is arranged on the rotor in a pivoted mode, at the locking position, one part of the elastic piece is clamped on the rotating shaft, and the other part of the elastic piece is stopped at the rotor. When the buckling piece is connected with the rotating shaft in an anti-rotating mode, the buckling piece is connected with the elastic piece so that the elastic piece can be kept at the locking position.
Description
technical field [0001] The invention relates to the field of electric technology, in particular to a peristaltic pump and a portable dialysis device with the peristaltic pump. Background technique [0002] Portable dialysis equipment is usually used for extracorporeal hemodialysis treatment, and usually includes a peristaltic pump, a dialyzer, and the like. Peristaltic pumps usually include motors, pump heads, rotors, and hoses. In medical technology, peristaltic pumps require new hoses after each treatment. Moreover, for the purpose of cleaning, the rotor needs to be disassembled and cleaned after each dialysis, and then installed in the pump head after cleaning. In the prior art, the lock hook of the coupler is usually used to lock the rotor in the pump head. After the rotor is assembled with the pump head, the rotor is locked to the rotating shaft of the motor, and due to the resistance of the motor, the rotor is difficult to be manually rotated for adjustment.
