[0001] The present invention relates to the technical field of lower limb thrombus rehabilitation and prevention equipment, and particularly relates to an integrated device for mechanical ventilation lower limb thrombus prevention and ankle pump exercise. Background Art

[0002] Ankle pump exercise, as the name implies, is to make the ankle act like a water pump to promote blood circulation and lymphatic return in the lower limbs. Ankle pump exercise can accelerate blood circulation in the affected limb, subside swelling, and prevent venous thrombosis in the affected limb caused by postoperative bed rest and immobilization; and it has the effect of enhancing muscle strength and avoiding excessive muscle atrophy. For patients who need to stay in bed and require mechanical ventilation after surgery, their limited mobility makes it impossible for them to exercise by themselves, which indirectly leads to the prone occurrence of venous thrombosis in the lower limbs of bedridden patients. Therefore, doctors usually recommend that patients perform ankle pump exercise to prevent lower limb thrombus. However, ankle pump exercise requires a certain amount of physical strength, which may pose a risk of affecting postoperative recovery for bedridden patients.
