Background

An air wave pressure therapeutic apparatus (also called a pneumatic circulation promoting apparatus or a pneumatic limb blood circulation therapeutic apparatus) is an internationally recognized apparatus for treating limb lymphedema, unsmooth venous return, promoting blood circulation and anticoagulation, and is a model of traditional Chinese medicine blood circulation promoting, stasis removing and massage principles.

The air wave pressure therapeutic apparatus is applied to the affected limb to pressurize sequentially, so that in the process of accelerating the backflow of the venous blood and the lymphatic tissue fluid, the lymphatic fluid and the venous blood can be rapidly driven to the proximal end of the limb, the pressure in the tissues of the limb is reduced, the blood supply of the artery is rapidly enhanced in the time of gas evacuation, the blood and oxygen supply of the tissues of the limb are rapidly improved, and metabolites and inflammatory pain-causing substances are eliminated. The repeated expansion and contraction of the air wave can achieve the effects of improving blood circulation, increasing skin surface temperature and expanding and activating blood vessels, is beneficial to resisting thrombosis, improving circulation, removing metabolic wastes in blood and enhancing the degree of oxygenation of limbs. The local blood circulation is improved, the blood perfusion and oxygenation of nerves are increased, and the oxygen consumption of the nerves is increased, so that the aim of improving the function is fulfilled, the numb symptom of limbs is obviously relieved, and the skin feeling is sensitive compared with that before treatment. Clinically, patients who insist on applying the medicine for about 1 week have obvious effects of numbness of the extremities and pain relief. In addition, the air wave pressure therapeutic apparatus has obvious curative effects on relieving limb edema, preventing lower limb venous thrombosis of patients lying in bed for a long time or braking patients such as hemiplegia, paraplegia, paralysis and the like, relieving muscle fatigue, relieving pain and the like.

The existing domestic and foreign air wave pressure therapeutic apparatus mainly comprises an air pump, an air duct, an air bag sleeve and the like, and the corresponding inflation working principle is that the air pump outputs pulsating air flow, and the pulsating air flow inflates the air bag sleeve through the air duct. The massage principle is as follows: according to the preset high, medium and low pressure values, after the main control machine inflates the sleeve, a certain pressure is formed in each air bag. When the first air bag is inflated, the second air bag is deflated, the third air bag and the fourth air bag are sequentially inflated/deflated, and the massage part of the air bag sleeve can not be selectively closed only in a single massage mode, and the pressure and the time are mechanically adjusted through a knob.
