Description

Ankle pump motion assistor

Technical Field

The utility model belongs to medical equipment, and particularly relates to an ankle pump exercise assisting device.

Background

The ankle pump movement is the movement through the ankle joint, plays a role like a pump, promotes the blood circulation and lymph backflow of the lower limb, prevents deep venous thrombosis of the lower limb, and simultaneously plays a role in preventing foot drop, lower limb muscular atrophy, ankle joint contracture and stiffness. Plantarflexion/dorsiflexion is the primary motion of the ankle joint, and plantarflexion/dorsiflexion motion is sometimes referred to as ankle joint motion. The plantar flexion/dorsal extension movement is the main movement for pushing a person forward, and is also responsible for the phase conversion of the gait during the walking process, and the plantar flexion/dorsal extension movement cooperates with the hip joint and the knee joint to form the normal gait of the person. The main muscles that perform the ankle pump movement: dorsal extension is mainly accomplished by the tibialis anterior muscle, and plantar flexion is mainly accomplished by the triceps surae.

The ankle pump movement is important for preventing foot drop, lower limb muscular atrophy and lower limb deep venous thrombosis of patients who are in coma, paralysis, postoperative patients, long-term bedridden patients and the like. The existing commonly used auxiliary device for preventing the foot drop of a patient is an ankle-foot orthosis, the ankle-foot orthosis can effectively promote the heel to land, swing to the ground of the toe and improve the walking speed by fixing the ankle joint of a human body or installing an elastic element at the ankle joint, but the ankle-foot orthosis cannot generate ankle dorsiflexion and plantarflexion motions, and has little effect on preventing the muscular atrophy of the lower limbs, deep venous thrombosis of the lower limbs and the atrophy of the muscular nerve group of the ankle joint. The automatic control auxiliary device adopts a motor winch to drive the bottom plate to alternately move, but the use effect is not ideal due to the complex structure. Therefore, the exercise rehabilitation of the patients still mainly depends on physical therapists to train the hands of the patients, the physical therapists perform passive activities for ankle joints of the patients when the patients are fully relaxed, and provide certain assistance or slightly impedance when the patients perform active ankle dorsal extension, and the method plays a certain role in preventing and rehabilitating foot drop, muscle atrophy of lower limbs and deep venous thrombosis of the lower limbs. However, the physical therapists are required to manually perform exercise rehabilitation, which is often influenced by the number, strength and experience of the physical therapists, and the rehabilitation is accumulated by the experience, and is supported by few quantitative data, and under the current situation that the physical therapists in China are lack, a plurality of patients often wait for the alternate treatment of one physical therapist, so that the patients are difficult to obtain timely treatment, and the best time for rehabilitation is lost.
