An ankle pump

Abstract

The invention provides an ankle pump comprising a connecting plate, a stepping motor, a transmission screw rod, a shank fixing device, a foot board, a foot fixing belt and a shank fixing belt. A rotor of the stepping motor is connected with the lower end of the transmission screw rod so that the rotation of the rotor is transmitted to the transmission screw rod; through the forward and reverse rotation of the rotor, the transmission screw rod telescopically drives the foot board to make dorsal stretch and plantar flexion movement. The ankle pump can effectively prevent lower limb vein thrombosis, lower limb amyotrophy and articular ligament contracture, can improve the symptoms and signs of venous return dysfunction diseases and can play an important role in promoting recovery of ankle joint functions.

Description

technical field [0001] The invention relates to the field of medical devices, more specifically an ankle pump, which can prevent lower extremity venous thrombosis, lower extremity muscle atrophy and joint ligament contracture, help to improve the symptoms and signs of venous reflux disorders, and have an effect on the recovery of ankle joint function. important role. Background technique [0002] Venous thromboembolism is the third major acute cardiovascular event after acute coronary syndrome and stroke, and the mortality rate can be as high as 20%. It is mainly caused by pulmonary embolism caused by deep vein thrombosis of the lower extremities. About 30% to 50% of patients develop post-deep vein thrombosis syndrome, causing long-term suffering to patients. The high fatality rate and high disability rate of lower extremity deep vein thrombosis seriously threaten life and health, pose a huge challenge to public health, and the overall incidence is on the rise.

Problems solved by technology

In addition, with the advent of an aging society and the increase in the incidence of cardiovascular and cerebrovascular diseases, the number of patients who are bedridden or inconvenient in the family has increased significantly. The functional exercise of the lower limbs in the nursing process is very important, but it requires a lot of manpower. The current medical market There is also a lack of low-cost, simple-designed, and effective small-scale equipment for lower limb functional exercise to prevent deep vein thrombosis of lower limbs, prevent or reduce complications such as muscle atrophy of lower limbs, contracture of joint ligaments, and foot drop.
