The invention relates to the field of medical instruments, in particular to a medical blood pumping device. The medical blood pumping device comprises a pump body, a first bolt, a bearing, a speed reducer support, a motor support and a second bolt, wherein a dismounting and mounting side plate is fixedly mounted on the right side of the pump body through the first bolt, an upper right connecting shaft and a lower right connecting shaft are rotatably connected to the upper portion and the lower portion of the left end of the dismounting and mounting side plate correspondingly. the left ends ofthe right upper connecting shaft and the right lower connecting shaft are fixedly connected with a driving roller and a driven roller correspondingly, two sets of driving spiral blades and driven spiral blades which are oppositely arranged are arranged on the left sides and the right sides of the outer walls of the driving roller and the driven roller symmetrically, the driving spiral blades and the driven spiral blades on the same side are matched with each other; the left ends of the driving roller and the driven roller are fixedly connected with a driving shaft and a driven shaft correspondingly, and the driving shaft is rotationally connected to the left side wall of the pump body through a bearing. The invention provides a blood pump which can continuously and stably output blood andadjust the blood transfusion speed according to actual conditions.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to a medical blood pumping device. Background technique [0002] Medical blood pumping devices (referred to as blood pumps) are widely used in the medical field. For example, in hemodialysis, since the pressure difference between the arteries and veins of the human body is not enough to push the blood into the dialyzer and finally return it, a blood pump is needed to guide it. blood flow. [0003] The medical blood pumping device used for hemodialysis in the prior art usually includes a rubber hose and a cam driven by a motor. One end of the rubber hose is connected to the patient's artery, and the other end is connected to the dialyzer. During the application process, with the rotation of the cam, the protruding part of the cam squeezes the rubber tube at intervals to push the blood in the rubber tube to flow and complete the blood delivery. Due to the above-mentioned structural ...
