Description
Technical Field
The invention relates to the technical field of external counterpulsation, in particular to a self-adaptive external counterpulsation bag sleeve control device.
Background
EECP is a passive adjuvant therapy for non-invasive treatment of ischemic diseases, and the development of the equipment is originated in China. In 1970, the professor of Zheng Sheng of Zhongshan university and the subject group thereof successfully developed independent intellectual property right-sequential pressurized external counterpulsation of air sacs of limbs, which is called EECP (enhanced external coronary pulsation), and was formally applied to the treatment of coronary heart disease, angina pectoris and the like in 1982, and was approved by the FDA in 1992, and was mainly used for stable or unstable angina, acute myocardial infarction, cardiogenic shock and the like. The european cardiology society of 2013 began to incorporate EECP therapy as recommended IIa in guidelines for stable coronary heart disease diagnosis and treatment. The device has the working principle that R waves are identified through ECG, air bags are sequentially inflated from the lower leg, the thigh and the hip from bottom to top to squeeze arterial blood flow of the lower half body, the blood flow is driven back to the upper half body in diastole, perfusion of important organs such as heart and brain is improved, venous return of the right heart is increased due to simultaneous compression of venous systems, the three-stage air bags are simultaneously exhausted in systole, and afterload of the heart is reduced.
However, the lower limb airbag device of the EECP has no substantial breakthrough in recent 30 years, the device is controlled extensively, the evaluation is single, and accurate intervention and regulation cannot be realized on the cuff device, so that the clinical optimal benefit is influenced. At present, lower limbs are wrapped in a thread gluing mode in hospitals, communities and rehabilitation medical institutions commonly used, the judgment standard of wrapping the lower limbs in a static state is that the height of a finger can be only held under a bag cover, but in EECP treatment, the traditional thread gluing type air bag can be loosened after being pasted in the air filling and exhausting process of treatment, and the height of a half-1 fist is probably held in the air exhausting process in about 30min of treatment; in addition, the existing bag cover can not adjust the attaching degree of the bag cover according to the indexes of the leg circumference and the like of the patient. In conclusion, the current cuff device not only brings technical troubles to the operation and guidance of clinicians, but also causes the attenuation of the treatment effect, thereby seriously affecting the optimal clinical benefit.
