Description

Technical Field

[0001] The invention relates to the field of postoperative recovery exercisers, in particular to an auxiliary training device for lower limb postoperative recovery. Background Art

[0002] During the recovery process after interventional surgery, many patients will face limited lower limb movement. Especially after interventional surgery involving important blood vessels such as the femoral artery, doctors usually use compressors to compress the patient's lower limbs to prevent the formation of blood clots. However, the patient's lower limb movement is limited, especially the movement of the thigh root or femoral artery area will be suppressed, resulting in the inability to move the lower limbs normally. Although some patients will perform simple ankle swings or upper and lower limb exercises to promote blood circulation, these voluntary exercises are often not sustainable, and patients often give up halfway due to pain, fatigue or discomfort.

[0003] Prevention of lower limb venous thrombosis is an important part of postoperative rehabilitation. Traditional exercise intervention methods require active cooperation from patients. However, patients' compliance is usually low and they are unable to continue effective exercise.

[0004] In order to solve the above problems, the prior art proposes a device for preventing lower extremity venous thrombosis, including the following:

[0005] 1) Publication No. CN119257920A discloses a wearable device for preventing lower extremity venous thrombosis. In this patent application, it includes a thigh sleeve, a calf sleeve is arranged below the thigh sleeve, a knee joint driving component is fixedly connected to the right side surface of the thigh sleeve and the calf sleeve, and 2-3 vein restraint belts are arranged on the rear surface of the calf sleeve. The present invention wraps the thigh and calf by arranging two upper and lower sleeves, and uses the knee joint driving component to drive the two sleeves to rotate relative to each other in an electric and gear transmission manner, thereby facilitating the bending between the thigh and the calf, helping the blood circulation of the leg, and preventing the formation of venous thrombosis; in addition, a vein restraint belt is arranged in the calf, and the restraining force of the calf is gradually reduced from bottom to top in the form of an inflated strip airbag, thereby accelerating the flow of blood in the vein.

[0006] 2) Publication No. CN118873355B discloses a multifunctional position pad for preventing deep vein thrombosis of lower limbs. In this patent application, it includes: a position pad body, on which a plurality of air bags are arranged; an inflation component, which is connected to the air bags through a trachea, and includes an air compressor, a buffer air bag, a control component and a valve, the air compressor is connected to the buffer air bag through a first pipeline, the buffer air bag is connected to the valve through a second pipeline, and the valve and the control component are controlled and connected; a magnetic therapy component, which is arranged on the position pad body; at least one fixed component, which is arranged on the surface of the position pad body; a baffle component, which includes a baffle and a driving component, the baffle is rotatably connected to one end of the position pad body, and the driving component drives the baffle to rotate. The present invention can prevent venous thrombosis of lower limbs, and can also massage the legs, promote blood circulation, and ensure the smoothness of blood flow. The baffle component can help patients do passive ankle pump exercises and maintain functional positions.

[0007] 3) Publication No. CN221470844U discloses an auxiliary exercise device for preventing lower extremity venous thrombosis. In this patent application, it includes: a base plate, and also includes: an anti-friction mechanism, which is slidably mounted on the top of the base plate; a buffer mechanism, which is rotatably mounted on the top of the base plate; wherein the anti-friction mechanism moves with the movement of the patient's heel to reduce the friction on the patient's heel, and the buffer mechanism rotates along the base plate to cushion the patient's leg when it falls. The utility model can reduce the friction on the patient's heel by the anti-friction mechanism moving with the movement of the patient's heel, which is convenient for reducing the patient's discomfort and improving the efficiency of auxiliary exercise, and can cushion the patient's falling leg by the buffer mechanism, reducing the situation where the patient's leg falls quickly and causes injury, and improving the reliability of auxiliary exercise.
