Abstract
The utility model relates to an adaptive drive system of an aortic blood pump position, belonging to the field of biomedical engineering. The system consists of an in vitro permanent magnet rotor (1), a brushless motor (3) and an in vivo aortic blood pump body (2), wherein an in vitro permanent magnet is a radially magnetized cylindrical permanent magnet, and the aortic blood pump body consists of a blood pump housing and a radially magnetized impeller arranged in the blood pump housing; and the in vitro permanent magnet is driven by the in vitro brushless motor, and the in vitro permanent magnet rotor drives the aortic blood pump to rotate to supply blood to the human body because of the presence of magnetic coupling. The invention adopts the in vitro rotating magnetic field to directly supply kinetic energy to the blood pump without built-in batteries and transcutaneous leads, so that the risk of infection is avoided, and the quality of life of patients is improved. The system can adjust and ensure that the in vivo blood pump and the in vitro permanent magnet rotor are parallel or form a minimum angle, and the position of the in vivo blood pump can be adjusted by the in vitro permanent magnet rotor.
Description
Technical field
The present invention relates to a kind of aorta blood pump position self adaptation driving device, belong to biomedical engineering field.
Background technology
Blood pump has become one of effective ways for the treatment of heart failure gradually, but in traditional blood pump system, great majority adopt the mode of internal batteries or percutaneous lead to come blood pump transmission energy in body.But no matter be the internal battery energy storage or transmit by percutaneous lead energy and all to have some disadvantages.These disadvantages mainly show: for the internal battery mode, because current battery technical limitations, can not provide energy for blood pump system for a long time, simultaneously because with whole blood pump system implant into body, increased the foreign body volume of inside of human body, therefore the probability of rejection of human body increase greatly, so this type systematic only to be fit to short-term auxiliary, can not the long-time continuous operation; Though and percutaneous lead energy delivery mode can resolution system the problem of operation continuously because lead can pass human body skin, therefore cause infection and rejection extremely easily, have a strong impact on patient's quality of life.
Summary of the invention
In order to overcome above-mentioned drawback, the invention provides a kind of external rotating excitation field and come directly not need internal battery and percutaneous lead that the aorta blood pump and the energy delivery system thereof of electric energy are provided for blood pump provides kinetic energy.
To achieve these goals, the technical solution used in the present invention is:
A kind of aorta blood pump position adaptive drive system comprises external PM rotor that is driven by brushless electric machine and the aorta blood pump body that places in the human aortic, and wherein, described external PM rotor is a cylindrical permanent magnet, radial magnetizing; Described aorta blood pump body comprises blood pump shell and helical form permanent magnet impeller, and impeller is installed in the blood pump shell, and the impeller radial magnetizing.
Described external PM rotor and the intrinsic impeller of aorta blood pump all adopt neodymium iron boron N50 material manufacture.
Beneficial effect of the present invention: the rotational energy of blood pump body provides by magnetic induction by external PM rotor, so do not need internal battery and percutaneous lead, has avoided the danger of infecting, and has improved patient's quality of life.In addition, owing to always change along with the position change of external PM rotor by magnetic induction blood pump body, so this device can be adjusted and guarantee dynamical system and become low-angle with the blood pump body at same plane meeting auto-paralleling or set, after external PM rotor locus is stable, this device can adjust dynamical system and blood pump body automatically near and rotate to the torque minimum position.
