Ventricle auxiliary system based on physiological signal

Abstract

The invention relates to a ventricle auxiliary system based on a physiological signal, which belongs to the technical field of the biomedical engineering. The invention relates to a ventricle auxiliary system which comprises a controller, a driving module, a blood pump, a signal collecting module and a displaying module, wherein the driving module is in communication connection with the controller, the blood pump is controlled by the driving module, the signal collecting module is used for collecting the working state of the blood pump, processing the working state of the blood pump and transmitting the working state of the blood pump to the controller, and the displaying module is connected with the signal collecting module and the controller and can display the state of the blood and theinformation of the controller. The ventricle auxiliary system is characterized by also comparing a human physiology detecting system which is connected with the controller by the signal collecting module and can detect the physiological states of blood pressure, blood temperature, heart rate and blood flow of the human body, and the controller has six modes: a normal mode, a suction treating mode, a lung gore treating mode, a signal collecting module failure treating mode, a pulsating mode and a starting mode. The invention can regulate the working state of the blood pump on the basis of detecting the physiological state of patients to adapt to the physiological requirement of the patients.

Description

technical field [0001] The invention belongs to the technical field of biomedical engineering and relates to a ventricular assist system. Background technique [0002] The ventricular assist system belongs to the category of artificial heart and is mainly used in the treatment of patients with heart failure. The ventricular assist system mainly includes a blood pump, a controller, and an execution and feedback mechanism. [0003] Internationally, the international patent WO2006 / 055745A2-heart pump remote data monitoring system declared by MICROMED CARDIVASCULAR, INC. of the United States in 2006 proposed a better design idea for the artificial heart control system: use the controller to control the blood pump, and wirelessly Communication media remote monitoring. The patent A61M 1 / 10 (2006.01) 20060101AF2007050-rotary blood pump pulsation control system filed in 2006 by Australia Woodard John et al. is a system for controlling the speed of a rotary blood pump, changing the...

Problems solved by technology

First, the above designs generally consume a lot of energy, all of which are above 15W, so that the practicability of the instrument will be reduced, especially when the patient cannot be charged quickly, a large amount of power consumption will make the patient's condition very dangerous

The second is that due to the large speed of the blood pump or the large rate of speed change, the damage to the blood is relatively large.

The third is that the speed of the blood pump in the artificial heart is not directly controlled according to the patient's physiological condition, so that the artificial heart works in the best state suitable for the patient's condition.
