Embodiment 1

[0059] Such as figure 1 As shown, the present invention provides a multi-stage magnetic transmission mechanically assisted circulation optimization system, the system includes a detection module, a decision module and an evaluation module, the detection module imports the patient's chest MRI image and non-invasively measures the patient's cardiac output based on the ICG method, In this way, the patient's anatomical data and cardiopulmonary cycle physiological data are obtained. The patient's anatomical data includes the positional relationship and distance of the heart, sternum, and chest body surface, and the physiological data includes the cardiac output, heart rate, and blood pressure of the heart. They are organized into Data tables (curves), while the detection module sends the above data and graphics to the decision-making module; the decision-making module is based on the multi-stage magnetic transmission model of the artificial heart, and uses an optimization algorithm ...

Abstract

The invention discloses a multi-stage magnetic transmission type mechanical auxiliary circulation optimization system, and belongs to the field of biomedical engineering. The system comprises a detection module, a decision module and an evaluation module. A patient MRI scanning image is imported into the detection module to obtain corresponding segmented images of the cardiac aorta, the chest riband the body surface, the segmented images and the measured cardiac output and blood pressure are sent to the decision module, and a blood pressure waveform is sent to the evaluation module; the decision module calculates the size of each stage of device in multi-stage magnetic transmission mechanical auxiliary circulation devices through the system based on a multi-objective optimization algorithm; and the evaluation module calculates evaluation values of the multi-stage magnetic transmission devices based on a weighted average algorithm according to quantified numerical values. The system has the high stability and portability.

Description

technical field [0001] The invention belongs to the field of biomedical engineering, and relates to a multi-stage magnetic transmission mechanical auxiliary circulation optimization system, which is used for optimizing a multi-stage magnetic transmission mechanical auxiliary circulation device, and has reliability and universality. Background technique [0002] Mechanical assisted circulation device is an effective solution for patients with heart and kidney failure, and artificial heart is a kind of mechanical assisted circulation. The currently commonly used one-piece artificial heart has the disadvantage of percutaneous wires and is prone to infection. The Extracorporeal Life Support Laboratory of Beijing University of Technology has designed an artificial heart extracorporeal magnetic drive system using the principle of magnetic coupling, patent 99126258.1 and patent 200910089092.4. The two-stage transmission device designed by these two patents can improve the transmiss...
