Problems solved by technology

This not only limits the clinical use of extracorporeal blood pumps (for example, there is usually no space for two sets of control hosts in an ambulance), increases the risk of death of the patient during the replacement process, but also increases the cost of use

Abstract

The disclosure relates to an in-vitro blood pump, a motor therefor and an in-vitro blood pump system. The motor for the in-vitro blood pump comprises a shell body, an actuating mechanism, at least onesensor and a motor drive control assembly, wherein the actuating mechanism is located in the shell body and is used for driving an impeller in a pump head of the in-vitro blood pump; the at least onesensor are located in the shell body; and the motor drive control assembly is located in the shell body and is used for controlling operation of the motor. Through integrating the motor drive controlassembly into the shell body of the motor, the dependence of the motor on a control host of the in-vitro blood pump can be remarkably lowered, and the risk of communication problem between the motorand the control host and the risk of failure of the motor drive control assembly can be remarkably lowered, so that the safety and reliability of the in-vitro blood pump can be greatly improved.

Description

technical field [0001] The present disclosure relates generally to the field of medical devices. More particularly, the present disclosure relates to a motor for an extracorporeal blood pump, an extracorporeal blood pump including the motor, and an extracorporeal blood pump system including the extracorporeal blood pump and a control host. Background technique [0002] When the heart loses its function of pumping blood (such as beating heart surgery, acute cardiogenic shock, etc.), a blood pump can be used to replace the heart to assist in maintaining blood circulation in the human body. According to implantability and clinical use, blood pumps can be divided into implantable blood pumps and extracorporeal blood pumps. Implantable blood pumps can be implanted into patients to maintain human blood circulation temporarily or for a long time, and are mainly used for transplant replacement therapy for patients with end-stage heart failure. Extracorporeal blood pumps can be use...
