Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a lower limb ankle pump movement counting device. Background Art

[0002] Ankle pump exercise is the flexion and extension of the ankle joint. The blood circulation of the lower limbs requires power, and the pump plays a role in the power of blood circulation. The flexion and extension of the ankle joint mainly involve the calf muscles. The contraction and relaxation of the calf muscles play the role of muscle pumps. This pump can promote the acceleration of blood circulation in the lower limbs, increase blood return, and prevent deep vein thrombosis. Therefore, the main function of the ankle pump is to prevent deep vein thrombosis in the lower limbs.

[0003] According to a Chinese patent application with patent number 202221446512.7, an ankle pump motion counting device includes: a support base plate, the support base plate is movably arranged on a bracket, and a first flexible belt for fixing the sole of the foot is also arranged on the support base plate; the bracket is fixedly arranged on a base, and the bracket includes a first vertical frame and a second vertical frame symmetrically arranged on both sides of the base, and arc holes are arranged on the first vertical frame and the second vertical frame corresponding to the two sides of the support base plate, and support members extending to the arc holes are arranged on both sides of the support base plate, and the first vertical frame and the second vertical frame are provided with arc holes. A connecting rod is also provided at the center position of the arc-shaped hole corresponding to the first vertical frame and the second vertical frame, and the connecting rod is hinged to the support member; a counting component, the counting component includes a travel switch, and the travel switch is arranged at the end of the arc-shaped hole; and a base, the base includes a bearing plate, through the mutual cooperation of the base, the first vertical frame, the arc-shaped hole, the travel switch, the tension spring, the support bottom plate, the first flexible belt, the support pin, the connecting rod, the ankle base support, the second flexible belt, and the second vertical frame, the ankle pump exercise counting device can be made to fit the patient's foot better, so that the patient can be convenient for training.

[0004] However, the ankle pump motion counting device requires the patient to actively perform ankle pump exercises. Patients who are unable to exercise on their own or who do not have enough physical strength cannot successfully complete the ankle pump exercise, which reduces the applicability of the ankle pump motion counting device. In addition, the ankle pump motion counting device cannot support the patient's calf, so that the patient needs to lift the calf when using the ankle pump motion counting device, so that the calf is in a suspended state, which reduces the patient's comfort when using it and increases the difficulty for the patient to complete the ankle pump exercise. For this reason, we propose an ankle pump motion counting device. Utility Model Content
