Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a lower limb deep vein thrombosis prevention and treatment instrument. Background Art

[0002] Approximately 73% of thrombi are generated in the deep veins of the lower extremities. For example, patients who maintain a sedative posture for a long time in the operating room or elderly patients who are bedridden for a long time may develop thrombi in the deep veins of the legs. Thrombosis can cause a variety of negative effects. For example, it can extend along the veins and cause obstruction of the venous outflow tract of the legs, which manifests as swelling of the legs and even leads to secondary infection; this phenomenon in the chronic stage can cause venous ulcers in the legs to fail to heal. Deep vein thrombosis is a common and difficult clinical disease and one of the most common venous diseases. Clinical manifestations: congestion of the lower limbs, ischemic necrosis of the limbs in severe cases, long-term treatment, partial or complete loss of ability to work, and thrombus detachment in some patients, causing pulmonary embolism and endangering the patient's life.

[0003] For patients who are bedridden for a long time or cannot get out of bed, there are currently sports equipment used to prevent deep vein thrombosis in the lower limbs. The essence of this type of equipment is an intermittently inflated device. An inflatable sleeve is wrapped around the lower limb and intermittently pressurized, so that the air flow pressure is intermittently pushed from the foot to the thigh, so as to achieve intermittent compression of the lower limb to promote and accelerate the return of blood to the lower limb, thereby preventing deep vein thrombosis in the lower limb. Its main drawback is that the internal parts of the instrument lead to a large product size, the inflatable sleeve used is a textile on the outside, and it is not disposable, which has the disadvantage of being difficult to clean and disinfect; the inflatable sleeve is relatively bulky, usually designed to wrap the foot, calf and thigh at the same time, and cannot be adjusted according to the limb size of different patients, affecting the pressurization effect when the product is used; when the pressure is high, it is even easy to cause local ischemia.

[0004] After searching, the Chinese patent publication number CN218652405U discloses a lower limb deep vein thrombosis prevention and treatment device, including a slide rail and a slide rail seat, a sliding base is movably installed on the slide rail, and two fixed seats are arranged alternately on the surface of the sliding base; a foot support plate that can rotate around an axis is installed between the two fixed seats, and the direction of the rotating axis is perpendicular to the slide rail; a stepper motor and a position encoder are respectively arranged on the outside of the two fixed seats, and are respectively connected to the two ends of the rotating shaft, and the stepper motor and the position encoder are connected to the controller module through cables. However, it was found in actual use that although the device can be used to perform ankle pump exercises on the patient's footsteps, for patients who have lost the ability to move their lower limbs, the toes of the feet cannot move autonomously, which may lead to limited muscle activity in the toe area, which is easy to increase the risk of deep vein thrombosis.
