specific Embodiment approach

[0038] Specific embodiments: the computer control unit 2 obtains four parameters of input pressure, blocking time, interval time and repetition times from the operation panel 7, and displays the group of parameters on the display panel. After pressing the start key on the operation panel 7, the electromagnetic valve 4 is closed, the air pump 3 works, the cuff 5 is inflated and expanded to pressurize the limbs, and the pressure sensor 6 transmits the real-time pressure value to the computer controller unit 2, and displays it on the display panel. 8 shows that the blood flow sensor 9 transmits the detection result to the computer control unit 2, and the air pump 3 stops working after the blood flow is blocked. After the blocking time is reached, the electromagnetic valve 4 is opened, the pressure in the cuff 5 is released, and the pressurization process is repeated when the interval time is reached, and the process goes round and round until the preset number of repetitions is co...

Abstract

The device of the invention blocks limb arterial bloodstream through quantified intermittency, promotes angiogenesis substance, such as vascular endothelium growth factors and the like through repeat induction of physiological ischemia stimulation, promotes pathologic ischemia position collateral circulation formation to form a mechanism of vascular biological bypass, thus increasing ischemia position blood flow volume, improving and treating ischemic diseases. The device of the invention can block arterial bloodstream of upper limbs or lower limbs to perform physiological ischemia training without causing pathologic ischemia damage, is small and portable, and is used for single limb large-scale intelligent control device or multiple limbs large-scale intelligent control device of plural objects.

Description

[0001] The device of the present invention quantitatively and intermittently blocks the arterial blood flow of limbs, and promotes angiogenesis substances such as vascular endothelial growth factor (Vascular endothelium growth factor, VEGF) by repeatedly inducing physiological ischemic stimulation, and promotes the formation of collateral circulation at pathological ischemic sites. , that is, the mechanism of forming a "biological bypass" of blood vessels, increasing blood flow in ischemic parts, and improving and treating ischemic diseases. Background technique [0002] 1. Ischemic stimulation and angiogenesis: Ischemic diseases include coronary heart disease, cerebrovascular disease and cerebral infarction, peripheral arterial disease and arterial thrombosis, etc., which are the most common diseases that endanger human health. Effective collateral circulation formation is a self-protection mechanism in ischemic diseases, and it is also an important therapeutic mechanism. Isc...
