Description

Technical Field

[0001] This utility model relates to the field of ankle pump exercise, specifically an ankle pump exercise assistive device. Background Technology

[0002] Ankle pump exercises are centered on the ankle joint, using the rhythmic contraction and relaxation of the soleus and tibialis anterior muscles of the calf to act as a pump, thereby accelerating venous blood flow in the lower limbs, relieving blood stasis, and reducing the occurrence of deep vein thrombosis (DVT). These exercises include plantar flexion: pointing the toes down 40° to 50°, holding the maximum downward position for 5 seconds; dorsiflexion: pointing the toes up 20°, holding the maximum position for 5 seconds; and circumduction: performing a 360° rotation around the ankle joint. During plantar flexion (pointing the toes), the triceps surae contract and shorten, while the tibialis anterior relaxes and lengthens; during dorsiflexion (pointing the toes), the tibialis anterior contracts and shortens, while the triceps surae relaxes and lengthens. When muscles contract, blood and lymph are squeezed back to the heart; when muscles relax, fresh blood is replenished. Ankle pump exercises can stimulate lower limb muscle contraction, accelerate blood return, promote swelling reduction and limb function recovery, strengthen muscles, and prevent muscle atrophy. They can also accelerate the flow of blood in a hypercoagulable state, inhibiting the formation of deep vein thrombosis (DVT) in the lower limbs. Multiple studies have confirmed the significant effect of ankle pump exercises in preventing DVT.

[0003] However, due to incorrect posture during actual exercise, patients often find it difficult to achieve the standard of ankle pump exercises in plantar flexion and dorsiflexion, thus failing to effectively prevent deep vein thrombosis in the lower extremities. Utility Model Content
