Blood pump control device based on physiological parameters

Abstract

A blood pump control device based on physiological parameters relates to a control mode of a blood pump. The device comprises a multichannel data acquisition module and a data processing module, wherein the multichannel data acquisition module is arranged for acquiring a heart rate signal, a blood pressure signal before blood pumping, a blood pressure signal after blood pumping, a blood temperature signal, a blood pump outer surface temperature signal, a blood pump blade revolving speed signal, a blood pump voltage signal and a blood pump current signal and sending to the data processing module; the heart rate signal, the blood pressure signal before blood pumping, the blood pressure signal after blood pumping, the blood temperature signal and the blood pump outer surface temperature signal pass through an amplifying circuit, a filtering circuit and an A / D switching circuit in sequence; and the data processing module is arranged for receiving the signals from the multichannel data acquisition module, acquiring related signal values and then controlling the power of the blood pump according to the signal values by using a blood flow volume control algorithm. The blood flow volume can be regulated according to the measured physiological parameters so as to balance the blood pump output flow and the actual flow required by human body.

Description

technical field [0001] The blood pump control device based on physiological parameters relates to a blood pump control method. Background technique [0002] Internationally, the patent A61M 1 / 10 (2006.01) 20060101AF2007050 filed in 2006 by Australia Woodard John et al.: a rotary blood pump pulsation control system is a system for controlling the speed of a rotary blood pump. Changing the speed of the blood pump to generate pulsating pressure requires a higher motor. In the artificial heart introduced in patent 200580038932.4. and US 20040215050A1, the blood pump flow rate is used as the control signal, and the working state of the blood pump is controlled by a certain control method. However, since this control mode is based on the state of the blood pump rather than the state of the patient, and does not consider the interaction between the blood pump and the human body, it is not humanized enough and will not be completely suitable for the patient's condition.

However, since this control mode is based on the state of the blood pump rather than the state of the patient, and does not consider the interaction between the blood pump and the human body, it is not humanized enough and will not be fully suitable for the patient's condition

[0003] In China, the patent CN1446592 of Professor Bai Jing of Tsinghua University, etc.: the optimized non-constant speed control method of the miniature axial flow blood pump is based on the optimization model for adjusting the speed of the blood pump composed of the objective function, control parameters and limiting conditions method, these model controls do not fully take into account the relationship between the blood pump and the human body, and the regulation of the human body is not accurate enough
