[0002] Venous thromboembolism, as the name suggests, refers to the coagulation of blood in the veins to form blood clots, which can cause complete or partial blockage of the blood vessels. These include deep vein thrombosis (DVT) and pulmonary thromboembolism (PTE). Usually, patients experience symptoms such as swelling of the affected limb, pain, chest pain, and hemoptysis. Since venous thromboembolism is an acute disease with a high mortality rate, it is easily induced when the patient is in a state of postoperative surgery, bedridden due to a serious illness, fracture fixation, or sitting still for a long time. At this time, it is necessary to use venous thromboembolism protection equipment to do a good job of daily exercise prevention.

[0003] However, in the current existing technology, soft pillows or cushions are usually used clinically to support the affected limb to achieve the purpose of lifting it. This method is relatively unstable and can easily cause the affected limb to slide to the side and lose the supporting effect. It also includes the use of manual timed auxiliary massage to promote blood circulation in the affected limb. This method is time-consuming and labor-intensive, requires a large amount of operation, and cannot achieve the effect of automatically lifting and exercising the affected limb. Therefore, a device for protecting against venous thromboembolism is proposed. Utility Model Content
