New external counterpulsation device(product model: P-ECP/T) is based on modern medicine, biomedical engineering, gas dynamics, computer technology, embedded technology, modern control technology and modern industrial design. Higher precision control, greater security of the treatment and better therapeutic effect of external counterpulsation are reached. The new device is not only stable and comfortable, but equipped with the characteristics of refined appearance, small size and low noise.

Currently, we have already developed five types ECP products. Type P-ECP/T is split-type product which divide the machine to two parts, the bump and the bed. Type P-ECP/TI integration product which integrates the bump in the machine body. Type P-ECP/TM product is mobile external counterpulsation device which has smaller size and can be moved conveniently. Type P-ECP/TC is professional machine for children. All the types above can give external counterpulsation on legs and buttocks, and we can support these types with upper limb cuffs. Type P-ECP/TF product is external counterpulsation for family's health care.

The Principle of External Counterpulsation (EECP)
The external counterpulsation, supported by modern scientific theory, well performed by computer and digital electric control, is a noninvasive way to improve the circulation and further treat the ischemic disorders of heart, brain and kidney, which appears as an unique equipment composed of a host computer, a bed and a series of pneumatic compressive cuffs around the lower extremities and buttocks, or even the four limbs.

The principle of external counterpulsation is described as the following. Trigged by the R waves in the cardiac electricity, the cuffs are inflated during the diastolic period in sequence from the distal part to the proximal. The compression of the inflated cuffs on the limbs and buttocks will make the blood there backflow to the aorta to elevate the aortic pressure and blood volume, therefore increase the perfusion of those vital organs such as heart, brain and kidney. While before the systolic phase, the cuffs are deflated rapidly, thus the limb vessels are decompressed consequently. As a result, the peripheral resistance drastically falls. This facilitates the blood ejected from ventricle to flow promptly into the extremity arteries through aorta. To complete the treatment, the equipment inflates and deflates the cuffs according with the cardiac period.
