Embodiment Construction

[0043] The solutions in the embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0044] Such as figure 1 As shown, the specific implementation of the present invention includes a blood pump, a safety monitoring module, a hemodynamic parameter control module, and an auxiliary control module. The safety monitoring module, the hemodynamic parameter control module, and the auxiliary control module are all connected to the final speed variable of the blood pump output module.

[0045] The safety monitoring module is configured to judge whether the working state of the blood pump is abnormal according to the blood pump motor current measured by the sensor, the sound of the blood pump running, the flow rate of the blood pump and the working temperature, and if an abnormality occurs, increase or decrease the speed of the blood pump; safety monitoring The sensors of the module include current sensors, sound sensors,...

Abstract

The invention discloses a multi-level and multi-target left ventricular auxiliary blood pump physiological control system. It includes a safety monitoring module, a hemodynamic parameter control module and an auxiliary control module, all of which are connected to the final speed variable output module of the blood pump. The safety monitoring module judges whether the working state of the blood pump is abnormal based on the blood pump motor current, blood pump running sound, blood pump flow rate and working temperature measured by the sensor; The dynamic parameters adjust the speed of the blood pump to realize the control of the aortic pressure; the auxiliary control module adjusts the speed of the blood pump according to the heart rate, motion acceleration and respiratory rate measured by the sensor. The invention can prevent various abnormal working conditions of the blood pump and at the same time allow the perfusion of the blood pump to meet the needs of various physiological states of the human body.

Description

technical field [0001] The invention belongs to the category of artificial heart control in the field of biomedical engineering, and specifically relates to a multi-level and multi-target left ventricular auxiliary blood pump physiological control system. Background technique [0002] The ideal control system of the rotary blood pump must sense the physiological changes of the human body in real time to meet the physiological needs of the human body. At this stage, there are many pressure-based control methods, flow-based control methods, and heart rate-based control methods at home and abroad, and the control objectives are relatively single. Since the human physiological system is a complex nonlinear time-varying system, the single-target control method cannot satisfy the changing physiological needs to the greatest extent. [0003] In actual situations, as the patient's activity status changes, an acceleration will be generated, and the direction of the force will be par...
