Description

TECHNICAL FIELD

[0001] The utility model relates to postoperative nursing technical field, specifically relates to a dorsiflexion movement nursing auxiliary device. BACKGROUND

[0002] The ankle joint is rigid and dorsiflexion is limited due to immobilization after ankle joint fracture surgery and after ankle joint plaster fixation surgery. The lower limbs of the hemiplegic side of partial stroke patients are limited in passive dorsiflexion due to factors such as inability to flex and extend the ankle joint, muscle spasm, and increased muscle tension. When the above-mentioned patients are treated in rehabilitation, the rehabilitation therapist needs to treat the ankle joint of the patient to restore the dorsiflexion angle of the ankle joint. However, due to the short force arm of the ankle joint, the rehabilitation therapist cannot achieve stretching by resisting muscle tension through manual force, or cannot achieve the required treatment time through manual stretching. The operation threshold is high, and it is time-consuming and laborious, and the labor intensity of medical staff is large. The traditional method of "stepping on an inclined plate against a wall" forces the affected ankle joint to passively dorsiflex by pressing down with its own weight, but the muscle tension is large and the ankle joint is contracted at the beginning of rehabilitation. When the "inclined plate" training is performed, the forefoot of the affected side often contacts the inclined plate, and when the body weight is pressed down, the pressure variable cannot be controlled, and the patient often cannot complete the training due to forefoot pain. Moreover, the patient's body leans against the wall during the training, and the inclined plate forms a forward force, which easily causes the inclined plate to slide forward and causes the risk of injury such as falling.

[0003] The patent No. CN219538800U discloses a dorsiflexion movement nursing auxiliary device, which includes a bottom plate for the lower leg of a patient to rest on and a vertical plate arranged on the bottom plate. The inner plate surface of the vertical plate forms a matching surface for the patient's foot to press against. The vertical plate includes a rigid plate horizontally hinged to the bottom plate through a first hinge seat, and a flexible plate fixed to the top end of the rigid plate. A foot cover or a finger cover is arranged on the flexible plate to position the patient's toe, and a dorsiflexion restraint belt is arranged on the rigid plate to position the patient's dorsiflexion. The auxiliary device further includes a traction rope for pulling the patient's toe forward and / or backward. The traction rope is wound around a rotating wheel and the traction end is tied to the top end of the flexible plate. The utility model can ensure low operation threshold while ensuring the dorsiflexion movement effect.

[0004] But the dorsiflexion movement nursing aid still has the following problems in use: 1. The dorsiflexion movement nursing aid can only perform rehabilitation training on a single foot, and cannot perform rehabilitation training on both feet at the same time, and the practicability is poor; 2. The dorsiflexion movement nursing aid does not have a locking structure when in use, and the traction rope can continue to be pulled out and retracted for a period after the handle is stopped, the accuracy is not high, and the leg is easily injured; 3. The dorsiflexion movement nursing aid is a one-piece structure, and the patient needs to fix the lower leg restraint belt and the dorsiflexion restraint belt on the corresponding parts of the lower limbs of the patient, which can cause inconvenience in wearing; 4. The dorsiflexion movement nursing aid has poor stability, and problems such as rope falling off are easily caused; 5. The force of the machine needs to be perceived by the patient and the patient, and if the patient has signs such as decreased perception around the ankle joint on the affected side, muscle and ligament injuries can occur during treatment.
