Abstract

The present invention provides a therapy instrument for myocardial ischemia, which is combined with power circuit, generation circuit of modulation wave, shaping circuit of modulation wave, modulation circuit, constant current source circuit, stimulating electrode, CPLD carrier generation circuit, carrier shaping circuit, output intensity control circuit and MCU. The therapy instrument has characters of non-invasive, non-pain sense electrical stimulation, overcoming body adaptability etc., and can treat patient with comfortable sense. The therapy instrument can assistant treat myocardial ischemia by skin spinal cord and fastigial nucleus electrical stimulation. The therapy instrument modulates the random signal of low-frequency slow change rhythm on the MF carrier signal with special spectrum structure by method of pulse amplitude modulation, and loads LF current to human skin spinal cord and fastigial nucleus with forms of current by surface electrode. The therapy instrument can treat myocardial ischemia by improving coronary blood flow, reducing myocardial oxygen consumption, controlling pain and protecting neurogenic neuroprotection.

Description

technical field

[0001] The invention relates to a device for assisting physical therapy for patients with myocardial ischemia in a hospital, and belongs to the technical field of medical devices. Background technique

[0002] Coronary heart disease is one of the main diseases that threaten human health and life at present. It is a heart lesion caused by atherosclerosis of the coronary artery and its branches, resulting in stenosis or obstruction of the lumen. It is mainly characterized by insufficient blood supply to the heart, so it is also called ischemic heart disease. Improving myocardial ischemia and controlling angina pectoris are the basic principles for the treatment of coronary heart disease. There are many ways to treat myocardial ischemia, including lifestyle changes, various drug treatments, angioplasty, and coronary artery bypass grafting. With standard treatment, the vast majority of patients can control symptoms and improve myocardial ischemia. However, the...
