Problems solved by technology

[0003] The purpose of the present invention is to overcome the risks and inconveniences of existing European and American cardiac contractility regulators (CCM) devices in practical applications and the tolerance problems of in vitro electrical stimulation, and to provide a method for releasing ventricular insufficiency through the skin in vitro. Periodic high-frequency electric wave stimulation can promote the strengthening of the myocardial contractility of the heart, so as to achieve the purpose of treating heart failure and cardiomyopathy. In vitro percutaneous heart failure treatment instrument

Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 As shown, the extracorporeal percutaneous heart failure therapeutic apparatus 5 is composed of two parts: one is a trigger circuit 6, which determines the ventricular refractory period through the electrocardiogram signal 4; the other is a high-frequency stimulation circuit 7, which releases a High frequency electric wave 8 stimulates the myocardium.

[0014] In vitro, the electrocardiogram signal 4 is detected by the electrocardiogram machine 3 through the skin detection electrode 1 and is output to the extracorporeal percutaneous heart failure treatment instrument 5; the trigger circuit 6 determines the ventricular refractory period through the electrocardiogram signal 4, and the high-frequency stimulation circuit 7 is activated in the ventricle. During the response period, the high-frequency electric wave 8 is rele...

Abstract

The invention relates to an external percutaneous heart failure therapeutic instrument. A application method comprises detecting electrocardiogram signals through an electrocardiograph operated outside a human body, determining a ventricular refractory period through the electrocardiogram signals, and stimulating myocardium by releasing high-frequency electric waves to a heart by the external percutaneous heart failure therapeutic instrument at the ventricular refractory period to increase myocardial contractility. Compared with the prior art, the external percutaneous heart failure therapeutic instrument is advantaged in that the instrument not only solves a problem of European and American CCM machine electrode internal-placement causing injuries and a problem of external electrical stimulation tolerability.

Description

technical field [0001] The invention relates to a medical device for releasing high-frequency electric wave stimulation in the refractory period of the ventricle to the heart in vitro to strengthen the contraction force of the myocardium so as to treat heart failure and cardiomyopathy. Background technique [0002] At present, the well-known European and American cardiac contractility modulation (cardiac contractility modulation, CCM) device is to place electrodes into the heart, release electrical stimulation during the refractory period, and strengthen the myocardial contraction, thereby achieving the purpose of treating heart failure and cardiomyopathy; Electrical stimulation during the refractory period in the body can achieve the purpose of stimulating and treating heart failure and cardiomyopathy with only 1M and 5-8 volts of electric waves; greater risk. However, the electric wave of electrical stimulation in the refractory period outside the body must reach 1.5-2M a...
