Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a training device for preventing lower limb venous thrombosis. Background Art

[0002] Lower limb venous thrombosis is a common peripheral vascular disease that mainly occurs when patients are immobile for a long time, such as long-distance travel, bed rest, or during the recovery period after surgery. The occurrence of lower limb venous thrombosis not only causes uncomfortable symptoms such as leg swelling and pain, but may also cause serious complications such as pulmonary embolism, and even be life-threatening. Therefore, preventing the occurrence of lower limb venous thrombosis is particularly important. Currently, the methods for preventing lower limb venous thrombosis mainly include drug prevention, physical therapy, and exercise training. Although drug prevention is effective, it may be accompanied by side effects and is not suitable for all patients. Physical therapy and exercise training reduce the risk of thrombosis by promoting blood circulation. An auxiliary training tool is used to prevent bedridden patients from suffering from venous thrombosis. However, existing auxiliary training tools are generally simple in structure, making it difficult to adjust the training intensity. In addition, the auxiliary training tools are generally placed directly on the bed. During training, due to the certain range of movement, the stability is poor, and the device is easily displaced, resulting in poor training effect. To this end, we proposed a training device for preventing lower limb venous thrombosis to solve the above problems. Utility Model Content
