Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a passive ankle pump exerciser. Background Art

[0002] In clinical work, there are many bedridden patients in hospitals. Insufficient blood perfusion in their limbs can lead to neuromuscular atrophy, and slow blood flow can lead to lower limb venous thrombosis, which seriously affects the health of patients. The ankle pump exerciser in the prior art can effectively alleviate the above problems. The patient fixes his feet on the ankle pump exerciser, and the ankle pump exerciser drives the patient's feet to move. During plantar flexion (toes facing down), the triceps surae muscle contracts and shortens, and the tibialis anterior muscle relaxes and stretches; during dorsiflexion (toes facing up), the tibialis anterior muscle contracts and shortens, and the triceps surae relaxes and stretches. When the muscles contract, the blood and lymph fluid of the tibialis anterior muscle contract and shorten, and the triceps surae relax and stretch. When the muscles contract, they are squeezed and flow back, and when the muscles relax, fresh blood is replenished. By simply flexing and extending the ankles in this way, the blood circulation of the entire lower limbs can be effectively promoted.

[0003] In Chinese patent application No. 201821892426.2, patent name "Ankle Pump Exerciser" discloses an ankle pump exerciser, including a leg fixer and a foot fixer installed at the bottom of the leg fixer, the foot fixer includes a base plate, a servo motor is installed on the top of one of the mounting rings, and the leg fixer includes a fixing sleeve. The ankle pump exerciser, by setting the fixing sleeve and the base plate, is convenient for limiting and fixing the patient's legs and feet, and has a simple structure and strong practicality. The base plate is rotated back and forth by the servo motor.

[0004] Although the ankle pump exerciser in the above-mentioned patent drives the sole of the foot to simulate active and passive ankle pump movements, which is convenient for promoting blood circulation in the patient's legs and preventing the risk of deep vein thrombosis, in this patent, the fixing device for fixing the patient's foot is an integrated design with the ankle pump exerciser, which cannot meet the needs of patients with different foot shapes. In addition, since electronic devices are also provided on the ankle pump exerciser, it is not convenient for medical staff to clean it after the patient uses it. Utility Model Content
