  The present invention relates to a pneumatic massage apparatus (venous thromboembolism for preventing venous thromboembolism) for inflating and contracting a bag body with compressed air to massage a body pressure part such as a lower limb and an upper limb and improving blood circulation. Disease prevention apparatus) and a control method thereof.

During or after the operation, it is necessary to rest on the bed, so it takes a long time to move the lower limbs and upper limbs. When the time during which the lower limbs and upper limbs are not moved is prolonged, the blood tends to accumulate in a thick sinus without a valve in the muscle. Normally, the blood in the vein is sent back to the central side due to the contraction of the muscle at that site, but if the muscle strength is reduced, the blood flow becomes insufficient and the blood flows into the deep veins in the lower limbs and pelvis Because of stasis, blood clots may form. In addition, when sitting in a narrow seat such as a passenger plane for a long time, congestion of the deep veins of the lower limbs occurs. Thrombus also occurs in deep veins during major orthopedic surgery, fractures of the pelvis and femur (venous thrombosis). When a thrombus occurs in a vein, it causes pain, swelling, and tenderness at that site. Furthermore, if the thrombus (clotting clot) grows large and then flows through the inferior vena cava, right atrium, right ventricle to the lung, the pulmonary artery is embolized, causing chest pain, dyspnea, blood clot, etc. (venous thromboembolism) .

As a method for preventing venous thromboembolism, it is known that a method of promoting blood flow in a vein by intermittently pressing an upper limb or a lower limb is effective. As a device for carrying out this method, a cuff that is wound around a predetermined site such as a lower limb of a living body and capable of changing the compression pressure is provided, and the cuff is used to compress the site so that blood flow in the vein can be obtained. A device for preventing venous thromboembolism that prevents venous thromboembolism by promoting it has been proposed. If the blood flow in the vein is promoted, venous thrombosis is prevented, so that venous thromboembolism is also prevented. In particular, this venous thrombosis is likely to occur in the calf of the lower limb. Conventionally, a cuff (inflatable bag for compression) is worn around the body such as the lower limbs and upper limbs, and compressed air is supplied to the bag to cause expansion and contraction. Pneumatic massagers are already known for promoting and preventing venous thrombosis. In this type of massager, there is a squeezing-up method in which compressed air is supplied to a cuff provided with a plurality of bag portions, and the inflated and contracted portions are repeatedly pressed to pressurize the pressurized portion.

  Compressed air is supplied to a plurality of pouches provided in bamboo cuffs in the cuff and repeated expansion and contraction to sequentially charge and deaerate from the periphery, compressing the pressured part, and venous blood between them Since the action of pushing out the center toward the center is continuously performed, the blood in the pressed part is promoted to return to the center.
