Approximately 73% or more of thrombi occur in the deep veins of the lower extremities. For example, patients who remain in a sedated position for extended periods of time in an operating room or elderly bedridden patients may develop thrombi in the deep veins of the legs. Thrombosis can cause a variety of negative effects, such as extending along veins leading to obstruction of venous outflow from the legs, manifested by swelling of the legs and even secondary infection; this phenomenon in the chronic phase can lead to non-healing venous leg ulcers.

Deep vein thrombosis is a clinically common difficult and serious illness and is one of the most common venous diseases. The clinical manifestations are as follows: the patients with the symptoms of stasis and swelling of the lower limbs and the serious limb ischemic necrosis can not be cured for a long time, the patients lose partial or all labor capacity, and partial patients can have thrombus and fall off to cause pulmonary embolism so as to endanger the life of the patients.

Aiming at patients who are bedridden for a long time or can not get out of bed for activity, an animal motion instrument for preventing the deep venous thrombosis of the lower limb is provided at present. The essence of these instruments is an intermittent inflation device, which wraps an inflation sleeve around the lower limb and intermittently pressurizes it to intermittently push the airflow pressure from the foot to the thigh, so as to intermittently press the lower limb to promote and accelerate the blood reflux of the lower limb, thereby preventing deep venous thrombosis of the lower limb. The main defects are that the volume of the product is larger due to more internal parts of the instrument, the used inflating sleeve is made of textile outside and is not disposable, and the defects of difficult cleaning and disinfection exist; the inflatable sleeve is heavy and is generally designed to wrap the foot, the shank and the thigh at the same time, and cannot be adjusted according to the sizes of the limbs of different patients, so that the pressurizing effect of the product in use is influenced; at higher pressures, ischemia is even more likely to occur.

In addition, patent CN 208770305U realizes the fore-and-aft and left-and-right movement of the ankle joint through a mechanical method, but the structure is complex, the control precision is poor, only the leg of the patient can be horizontally placed and moved backwards, and the rehabilitation of the patient is not facilitated.
