The increase of the fluid speed of the venous blood also has an anti-thrombotic effect. In the leg, the calf muscle pump is passively simulated. The venous and lymphatic drainage is considerably improved. The gradient pressure causes a movement from distal to proximal regions in the intercellular space, with healty vessels for absorption.

The aim of the functional principle of the gradient intermittent compression is not just the mere re-absorption of ultra-filtration into the venous system, but to carry absorbed protein into the lymphatic system. (Not the same as the number of air chambers in all therapy devices.) The main difference is to be found in the arrangement and number (1 to 12) of the treatment sleeve’s air chambers. Today, systems of intermittent pneumatic compression are manufactured worldwide. The proximal part of the oedema is also decongested, and the treatment area considerably enlarged. An improved decongestion of the lower extremities is reached by leg and hip sleeves. The fluid mobilized in the high pressure range may pass unhamperedly through the low pressure levels, which ensures a continuous flow through the entire extremity.įor the patient, the average pressure load is lower than with conventional devices. Instead of the treatment sleeves used up to then with equal pressure from distal to proximal, the gradient system realizes an ascending pressure decline. This system was improved by gradient pressure in 1994 (Fig. The first ever pressure controlled overlapping 12-level system for instrumental intermittent compression was developed by Eck (Germany) in 1979. One of these inventions was the pressure-wave-therapy (Wave) with 12-air-chambers by Strehler (Switzerland) in 1968. After an interval, the inflation cylcle begins once again. Once all the chambers are filled, the air is release simultaneously. The chambers are inflated in such a way that the next chamber is filled with air only after the one before has attained the desired treatment pressure. Accordingly, with the multi-chamber-system the oedema fluid is mobilised ascendingly. Instead, three adjacent air chambers generate a pressure build-up from distal to proximal. In the generation of newly developed devices, the treatment sleeve is no longer filled with just one tube and doesn’t compress into depth. The 1-chamber-system became less important after the superiority of the new multi-chamber-system was confirmed. In this system, the treatment sleeves consist of multiple air chambers which are firmly connected (Fig. 3).Īs a result of the growing use in therapy and on the basis of many suggestions from medical experts, a new type of device was developed, the multi-chamber-system. This treatment method was standard of therapy for many years (Fig. In the 1960s, the first commercial manufacturing of 1-chamber-air-systems was realized in the United States by Conrad Jobst (Erlangen). 2), which he used for the mechanical support of the peripheral metabolism and the prevention of thrombosis.Īlso in 1929, Schede (Leipzig) described a modified gluteal massage, and, in 1932, his first compression boots. In 1929, Hammersfahr (Magdeburg) described a rhythmically filling and draining 'air chamber' (Fig. In 1909, the first of today’s commonly known devices for instrumental intermittent compression was developed in Kassel, with a filling and draining treatment sleeve, called high-pressure massage (Fig. In 1902, for the treatment of arm oedema Hofmeister recommended the immersion of the affected extremity in an iron cylinder filled with mercury. It was about a 'force and suction pump': suction to generate a reactive hyperaemia, force to reduce the volume of the extremities.Īnother origin of instrumental therapy with rhythmic compression is the mercury massage. The first recorded publication on the application of pneumatic treatment of extremities dates back to 1834. Also the field of indication of this form of therapy has enlarged enormously. Numerous studies documented its lasting efficiency, which increased its significance over the last years. Next to bandages and compression stockings, instrumental intermittent compression has been standard for years now in the physical treatment of venous and lymphatic diseases. The overlapping air chambers generate a gliding pressure wave with high efficiency.
