Description

Technical Field

[0001] The present invention belongs to the field of auxiliary training, and specifically relates to an intelligent auxiliary training device for critically ill patients. Background Art

[0002] In the field of medical care, patients who are bedridden for a long time, such as postoperative recovery patients, patients in the intensive care unit, or patients who need to be bedridden for a long time due to other diseases, are at risk of deep vein thrombosis in the lower extremities. Deep vein thrombosis (DVT) is caused by slow or stagnant blood flow in the lower extremities, and blood coagulates in the veins to form thrombi, which may cause serious complications such as pulmonary embolism, threatening the life safety of patients.

[0003] Limitations of manual massage and passive movement: Currently, in clinical practice, medical staff often regularly massage the legs of patients or guide patients to perform simple passive leg-lifting exercises to prevent deep vein thrombosis in the lower extremities. However, these methods have many problems. For example, manual massage requires a large amount of manpower and time, and it is difficult to ensure uniform and consistent massage intensity and frequency; the passive movement assisted by patient family members is often not standardized, with poor movement effects, and it is also impossible to ensure regular performance;

[0004] Some existing auxiliary devices for preventing deep vein thrombosis in the lower extremities on the market, such as elastic stockings and intermittent pneumatic compression devices, although they can promote blood circulation in the lower extremities to a certain extent, also have some limitations. The pressure distribution of elastic stockings may be uneven, uncomfortable to wear, and the pressure effect will gradually weaken after long-term use; the intermittent pneumatic compression device has a relatively high price, relatively complex operation, and some patients may find it difficult to tolerate due to discomfort, and its simulation of leg movement is not natural enough and cannot completely replace normal human leg movement.

[0005] In view of this, the present invention is specifically proposed. Summary of the Invention
