Abstract

The invention relates to a non-contact circulation pump, which solves the technical problem that the pump body is easy to pollute the blood when the existing blood transfusion pump is in use, and there are hidden dangers to hygiene and safety. It includes a pump head, a motor and a rotating shaft, and the pump head It includes a pump body, the two sides of the pump body are connected with a first runner and a second runner, the second runner and the first runner are arranged symmetrically, the lower end of the rotating shaft is connected with the output shaft of the motor, and the upper end of the rotating shaft is connected with the pump body connection. The invention is widely used in the technical field of medical equipment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a non-contact circulation pump. Background technique [0002] With the development of medical technology, pumps will be used in the clinical blood transfusion process. The hose is connected to the blood transfusion pump, and the blood transfusion pump provides power to allow the blood in the hose to flow. The blood will flow through the pump body, the blood does not completely flow in the closed hose, the blood is prone to pollution when passing through the pump body, and there are health and safety hazards. [0003] In the clinical blood transfusion process, more and more blood component transfusion technology is used to transfuse the necessary components in the blood to the patient, thus replacing the whole blood transfusion method. Existing methods and equipment for collecting components in blood mainly include membrane-type apheresis and centrifugation with intermitt...
