Embodiment Construction

[0056] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0057] figure 1 An external counterpulsation system applying the optimal counterpulsation parameter determination method of the present invention is disclosed. In the system, the host 1 of the counterpulsation device plays a central control role, and the process of information interaction with the operator is connected to a control display screen 4 is realized, and the collection of its information is then realized by electrically connecting an electrocardiogram image acquisition module 51 and a pulse image acquisition module 52, the power source 20, the power parameter control unit 21, the distribution ball valve 22, the control valve 23 and a plurality of controlled The valve 23 controls the opening of the limb pressurizing device 24 to form its pressure drive unit, in which the power parameter control unit 21 and the control valve 23 are electrically conne...

Abstract

The invention discloses an optimal counter-pulsation parametric measuring method; intelligent software is integrated in an external counter-pulsation system, the corresponding optimal counter-pulsation parameters are optimized to provide for the corresponding individuals to be used in the following counter-pulsation period aiming at measurement of different individuals, an electrocardiogram and a pulse gram are obtained firstly, a group of initialization parameter set is given to be applied to an external counter-pulsation device, so as to start a limb pressurization device to carry out initialization counter-pulsation process, in the process, by utilizing the corresponding relation of the electrocardiogram and the pulse gram, the following parameters for counter pulsation are commonly measured and selected: pressurization starting time, pressure relief time, pressurization timing length, pressure relief timing length, pressurization dimension and pressurization speed, so as to form an optimal counter-pulsation parameter set to carry out counter-pulsation process after parameter optimization is carries out; in the invention, by optimizing the parameters, blood flow shearing stress of an arterial system of a patient is fully improved in the counter-pulsation process, so as to lead the counter-pulsation system to be applied to the treatment of cerebral and vascular diseases and precaution and health care.

Description

【Technical field】 [0001] The invention relates to the field of external counterpulsation, in particular to a method for determining optimal counterpulsation parameters. 【technical background】 [0002] External counterpulsation is a mechanically assisted circulation technique. Pressurize the lower body or upper limbs of the human body through mechanical methods to drive the blood circulation of the human body, increase the blood supply to the heart, brain, kidneys and other organs and limbs to improve their functions. The so-called "counterpulsation" is to pressurize the limbs and buttocks of the human body during the diastolic period, so that the blood in them flows back to the trunk and brain, generating a huge diastolic counterpulsation wave (Diastolic Augmentation, DA); when the heart turns into systole During the period, the pressure on the limbs is quickly released, allowing the blood vessels to dilate to accommodate the blood discharged from the heart, thereby reducin...
