Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an auxiliary ankle pump exercise device. Background Art

[0002] Ankle pump exercise refers to the movement of the ankle joint, which acts like a pump to promote blood circulation and lymphatic return in the lower limbs. Studies have shown that by simply flexing and extending the ankle, increasing the peak velocity of femoral vein blood flow can effectively promote blood circulation in patients, reduce the occurrence of lower limb venous thrombosis and promote the recovery of lower limb muscle strength.

[0003] In the ankle pump exercise, the "circular movement" that combines plantar flexion, inversion, dorsiflexion, and eversion of the ankle joint is more effective in increasing the peak velocity of femoral vein blood flow than doing ankle pump exercises alone. Existing ankle pump exercise devices all fix the movement direction of the ankle. The foot can only perform dorsiflexion or plantar flexion with the ankle joint as the point, and cannot perform inversion, eversion, etc., which has a poor effect on promoting blood circulation in the entire lower limb.

The connecting shaft 30 is detachably connected to the pedal hinge seat 2, and the connecting shaft 30 can rotate in the shaft hole formed by the first shaft cavity and the second shaft cavity.

[0046] When inversion or eversion is required, the first locking member 221 and the second locking member 211 are separated, and the hinged upper cover 22 is flipped open so that the connecting shaft 30 can be taken out of the first shaft cavity, thereby releasing the activity restriction of the movable footrest 3, and the patient's foot can be turned inward or outward through the movable footrest 3.

[0047] When dorsiflexion and plantar flexion movements are required, the connecting shaft 30 is placed in the first shaft cavity, and then the hinged upper cover 22 is buckled on the hinged base 21, and connected through the first locking member 221 and the second locking member 211, so that the hinged upper cover 22 is tightly buckled with the hinged base 21, thereby limiting the range of movement of the movable footrest 3 and allowing the movable footrest 3 to rotate with the connecting shaft 30 as the rotation axis.
