TECHNICAL FIELD

[0001] The utility model relates to leg rehabilitation technical field, concretely relates to a kind of rehabilitation medical bed for assisting double legs rehabilitation. BACKGROUND

[0002] In the field of rehabilitation medicine, for patients with impaired leg function or postoperative recovery, traditional rehabilitation methods often rely on manual massage, simple physical therapy and static rehabilitation equipment. Although these methods can help patients recover leg function to some extent, they have many limitations. For example, manual massage is limited by the strength and skill of the therapist, making it difficult to achieve long-term, high-intensity continuous treatment. Simple physical therapy such as hot or cold compress can relieve muscle tension, but it has limited effect on promoting muscle strength and flexibility. Static rehabilitation equipment often lacks adaptability to individual differences, making it difficult to meet the specific rehabilitation needs of different patients.

[0003] With the progress of science and technology, existing rehabilitation beds mostly use fixed massage structures or simple horizontal adjustment massage structures, which are difficult to adjust dynamically at multiple angles according to the leg position and shape of the patient, resulting in poor massage effect.

[0032] Working principle:

[0033] The user lies flat on the medical bed 1 with the legs stretched out, and the auxiliary rehabilitation structure is controlled by an external controller to massage the legs of the patient.

[0034] The first use mode is as follows: first, according to the positions of the two legs of the patient, the two motors two 5 are controlled to work, the motors two 5 drive the threaded rods two to rotate, drive the connecting seats 512 to displace and adjust the positions, and make the connecting seats 512 move to the positions above the legs of the patient through the sliding and limiting of the connecting sliding plates 511 and the limiting sliding grooves 411 for stable horizontal movement. The other motor two 5 drives the connecting seat 512 to move to the position above the other leg of the patient through the threaded rod two in the same way, and then the motor one 3 is started to drive the two groups of connecting seats 512 to move to the positions where the legs need to be stimulated and exercised through the sliding connection of the screw rod one 310 and the U-shaped plate 4.

[0035] Next, the electric telescopic rods 514 in the two connecting seats 512 are controlled to reciprocatingly extend and retract, the elastic extension structures 515 are slidingly driven downward in the mounting grooves 513, the plurality of massage universal balls 516 repeatedly press and massage the legs of the patient, the muscles are relaxed and the blood circulation is promoted, and thus the rehabilitation of the legs of the patient is accelerated.

[0036] Second use: first according to the position of the two legs of the patient, control two motor two 5 work, motor two 5 drive screw rod two rotation, drive the displacement adjustment position of the connecting seat 512, so that it moves to the upper of the patient's leg, and the connecting seat 512 is limited to slide through the connecting slide plate 511 and the limiting slide groove 411, and is stably moved horizontally, another motor two 5 is driven by screw rod two to move the connecting seat 512 to the upper of the other leg of the patient;

[0037] Next, control the electric telescopic rod 514 inside the two connecting seats 512 to extend, drive the elastic telescopic structure 515 to slide downward in the installation groove 513, and the plurality of massage universal balls 516 repeatedly contact and extrude the patient's leg, at this time, start the motor one 3 to drive the screw rod one 310 to rotate forward and backward to realize interval positive and negative rotation, so as to drive the U-shaped plate 4 to move back and forth, and the plurality of massage universal balls 516 on the two connecting seats 512 roll along the patient's leg to realize leg massage, promote leg muscle relaxation and blood circulation, so as to accelerate the recovery of the patient's leg;

[0038] Because the height of the human leg is different, the elastic telescopic structure 515 is used to realize elastic telescopic adjustment, the elastic telescopic structure 515 is composed of a telescopic groove 5151, a telescopic arc-shaped seat 5152, a spring 5153 and a telescopic seat 5154, the plurality of massage universal balls 516 are fixed in the arc-shaped distribution at the bottom of the telescopic arc-shaped seat 5152, when the plurality of massage universal balls 516 move to the high place, the telescopic arc-shaped seat 5152 is contracted into the telescopic groove 5151 of the telescopic seat 5154 under the action of force, and the plurality of springs 5153 are compressed to store energy, when the plurality of massage universal balls 516 move to the low place, the telescopic arc-shaped seat 5152 is under the action of small force, the plurality of springs 5153 rebound the telescopic arc-shaped seat 5152 to extend and tightly contact and extrude the leg, so as to realize the practical adjustment of the extrusion massage force on the leg.
