Abstract

The invention provides a suspension rotor blood pump and a pumping system, and relates to the field of artificial heart. The suspension rotor blood pump comprises a pump shell, a suspension rotor and an internal bracing-type journal; the suspension rotor and the internal bracing-type journal are located inside the pump shell; an inlet is formed in one end of the pump shell, and the internal bracing-type journal is located at the other end of the pump shell; the suspension rotor comprises substrates, blades and permanent magnet rotors; the substrates are arranged outside the internal bracing-type journal in a sleeving mode, and gaps are left, the blades are fixed to the sides, close the inlet, of the substrates, and the permanent magnet rotors are embedded in the substrates; the portion, close to the blades, of the pump shell is further provided with a water pumping chamber which is used for collecting blood and is communicated with the outside; a circle of stators corresponding to the permanent magnet rotors are fixed to the peripheral side of the pump shell. The suspension rotor blood pump is applied to the pumping system. According to the suspension rotor blood pump and the pumping system, the technical problem that blood contamination occurs when an existing blood pump is prone to axial leakage is solved.

Description

technical field [0001] The invention relates to the technical field of artificial heart, in particular to a suspended rotor blood pump and a pumping system. Background technique [0002] The heart pump is a device that partially or completely replaces the pumping function of the heart to assist in the treatment of patients with severe heart failure. It is divided into two types: internal transplantation and short-term use outside the body. Currently, the design of the motor and the pump head is usually used. [0003] The existing heart pump design can realize the basic functions of the heart pump, but because most of the motors are integrated with the pump head and directly drive, especially for the short-term use of the heart pump outside the body, it can only be discarded as a whole after use, which is relatively economical. Difference. Moreover, mechanical shaft transmission may cause axial leakage of liquid, resulting in blood contamination. [0004] Based on this, the...
