Description

External counterpulsation rehabilitation therapeutic apparatus and control method thereof

Technical Field

The invention relates to the technical field of medical rehabilitation instruments, in particular to an external counterpulsation rehabilitation therapeutic apparatus and a control method thereof.

Background

The diabetic foot is ischemic, neuropathic and neuroischemic lesion of foot caused by diabetes, and early shows blood supply deficiency symptoms such as lower limb cold foot skin temperature reduction, pain and the like and peripheral neuropathy symptoms such as paralysis, dullness and the like; in the later stage, foot muscle and bone necrosis, such as osteomyelitis, dry gangrene or wet gangrene, occurs, and amputation is inevitable. The diabetic foot can cause the walking limitation and the lifelong disability of patients, seriously affect the physical and mental health and the life quality, and has the trend of increasing the morbidity in China in recent years.

In clinic, the classification of the diabetic foot is 0-5 grade from light to heavy according to Wagner grade. Even at the lightest level 0, patients have significant poor blood circulation, inadequate perfusion, and neuropathy in their lower extremities and feet. Therefore, improving the hemodynamics of the lower limbs and feet of the patient plays a decisive role in the prevention, treatment and rehabilitation of the diabetic feet.

Currently, the clinical treatments for diabetic foot mainly include: 1) controlling blood sugar; 2) drug treatment; 3) antiplatelet and vasodilatation therapies; 3) non-invasive adjuvant circulatory therapies such as air pressure waves; 4) performing lower limb arterial cavity interventional therapy and blood vessel bypass operation; 5) amputation, etc.

Among them, the drug therapy is extremely effective for improving the hemodynamic environment of the lower limbs and feet; the cost of interventional operation is huge, and diabetic patients are easy to generate local thrombosis and new occlusion after stent operation, and in addition, the guide wire is difficult to pass through for vascular occlusion below the knee, and the small blood vessels of the lower leg, the foot are not suitable for interventional treatment. The nature of the air pressure wave therapeutic apparatus is not different from that of the lower limb massage, and the hemodynamic effect of the air pressure wave therapeutic apparatus is extremely limited because the air pressure wave therapeutic apparatus does not increase the blood supply of the lower limb substantially.

Modern external counterpulsation (enhanced external counterpulsation, EECP) is a non-invasive mechanical assisted circulatory therapy and device designed and developed by our country. As a representative product of advanced treatment and high-end medical instruments in China, the medical instrument is the medical instrument which passes FDA certification (1994) first in China. EECP is mainly used for the treatment of ischemic vascular diseases, including cardiac and cerebral vessels, peripheral great vessels and tissue capillaries, the curative effect covers the occurrence, acute stage and convalescent period of the diseases, and is clearly listed in the clinical treatment guidelines of cardiovascular and cerebrovascular diseases in the United states and Europe, and the recommended levels of the relevant guidelines are as follows: coronary heart disease, angina pectoris (IIa-IIb), and ischemic stroke (IIa). As a source of EECP in China, relevant basic research and device development are always in the front of the world, the clinical application is not only for traditional cardiovascular and cerebrovascular diseases, but also for peripheral vascular diseases and micro vascular diseases (such as fundus diseases, sudden deafness, sleep disorders, peripheral vascular disorders and the like), and EECP clinical treatment centers are established in various provinces and Hongkong and Australian regions in China at present. The EECP devices made in China are currently exported to more than 30 countries and regions, and EECP treatment centers are built in a plurality of international top-level medical institutions including the Meio hospital, the Keliflan medical center, the Harvard medical institute and the like. EECP is a very few of the therapies and devices that have the property of being completely proprietary to china and yet can be widely accepted internationally.

Because the initial design purpose of EECP is to rescue the patient with myocardial infarction, the three-stage counterpulsation mode from far end to near end and the immediate curative effect judgment standard with D/S ratio more than or equal to 1.2, which are used at home and abroad at present, can ensure the blood volume of the heart-returning blood and the blood supply of coronary artery to the utmost extent and also ensure the blood supply of important organs of the upper half. However, the above-mentioned operation modes and criteria may not be optimal for hemodynamic enhancement of the lower body, particularly the lower extremities and feet, and therefore a new counterpulsation intervention mode needs to be designed for clinical needs of hemodynamic enhancement of the lower body.

In addition, the diabetic foot patients generally have the problem of inconvenient walking, and the early symptoms are not easy to attach enough attention, so that the diseases gradually worsen to cause serious consequences. Therefore, the EECP treatment is positioned as a target of secondary prevention/rehabilitation and is transferred to a social rehabilitation service center and a family, and early prevention and early intervention and prognosis rehabilitation of patients are facilitated. However, the EECP devices for clinical use are not suitable for social and domestic applications due to their inherent characteristics, and mainly include: 1) the volume is large and heavy, the covered area of the counterpulsation bed is nearly two square meters, and the weight is over 200 kg; 2) the power consumption is high, the noise is large, the heating value is large, the clinical EECP device is generally close to or even exceeds 2.5 kilowatt hours, and the da power air pump causes obvious noise; 3) the integrated counterpulsation executing device can cause adverse events to an ulcer area of a patient with an ulcer on the lower leg or the foot by the lower leg bag sleeve.
