The rehabilitation device is composed of a transverse plate, a vertical plate, a track, a chain, a rotating shaft, a mobile station, a pedal, a first compression spring and the like.

The device comprises a slide block, a horizontal connecting rod, a fourth roller, a third roller, a horizontal supporting plate, a limiting spring, a second vertical plate, a second roller, a first roller, a pull rope, a tension spring, a first vertical plate, a vertical long hole, a third shaft, a third compression spring, an oblique splitting part, a spacing ring and a chamfering part; the components such as the back cushion and the music player realize the jacking massage device, and the purpose of avoiding bedsore is realized.

Aiming at a patient lying in bed for a long time, the patient leans against the pillow by head, holds the handle by both hands and lies on the bed board horizontally. Putting feet on the pedal, switching on a power supply, driving the first shaft to rotate by the motor, driving the second sprocket on the rotating shaft to rotate by the first sprocket on the first shaft through the chain, matching the left end of the rotating shaft with the screw hole arranged on the mobile station through threads, driving the mobile station and the pedal to move along the track, and realizing reciprocating motion by the motor under the control of the first travel switch, the second travel switch and the controller; the leg and the foot of the patient can be simultaneously bent, the training is mainly suitable for the long-term bedridden patient, and for the common bedridden patient without fracture, the leg or the foot can actively apply pedaling action along with the reciprocating movement of the mobile platform, so that the exercise effect is better; the leg of the fracture patient can move without binding restriction, so that the ankle and the achilles tendon are pulled, the blood circulation of the patient is promoted, and the exercise position and the exercise amplitude are obviously superior to those of the prior art.

The motor outputs power to a buffer device in the jacking massage device through a sliding block, a first shaft, a second shaft, a first travel switch, a second travel switch, a horizontal connecting rod, a fourth roller and the like, and the buffer device comprises a third roller, a second vertical plate, a horizontal supporting plate, a limiting spring, a second roller and the like which are in abutting joint with the adjacent fourth roller. The buffer device is used for relieving the output rigidity of the motor output through the fourth roller column and reducing the impact discomfort of the massage to the patient. In addition, the connecting strips are arranged on the outer sides of the second lifting lugs connected with the second rollers and the outer sides of the first lifting lugs connected with the two shaft ends of the first rollers, so that the assembly precision requirement of parts such as a horizontal supporting plate, a first vertical plate and the like and a second groove is reduced, and the conduction rigidity between the second rollers and the first rollers is further reduced.

The first roller column is connected to the lower end of the first vertical plate through the first lifting lug, and the vertical long holes penetrating through the vertical surfaces of the left side and the right side are formed in the first vertical plate, so that the requirement that the first vertical plate can have the moving amplitude in the up-and-down direction while penetrating through the third shaft can be met. When the patient's tie lies on the bed board, along with the rotation of primary shaft lead screw portion, the slider uses the secondary shaft as the track, carry out horizontal migration, horizontal connecting rod moves along with the slider simultaneously, the fourth roller installed on horizontal connecting rod also carries out horizontal migration, the third roller among the fourth roller striking buffer in proper order, lead to upwards lifting up in proper order with the second riser of third roller column connection, then through second roller and the connecting strip of connecting in the second riser upper end, carry out the jacking action to the first roller of first riser lower extreme. Each first vertical plate is separated through a spacing device, the spacing ring penetrates through the third shaft and is arranged between the first vertical plates, and one end, close to the wedge part of the side wall on the left side of each first vertical plate, of the spacing ring is provided with a chamfer part, so that the first vertical plates are jacked right above and simultaneously participate in horizontal displacement movement under the action of the wedge part and the chamfer part, and therefore the back of a patient lying on the bed plate is jacked upwards, and horizontal pushing massage is carried out simultaneously.

Along with the rotation of lead screw portion, the fourth roller that the horizontal connecting rod is connected also triggers the different third roller of jacking in succession, under controller and first, two travel switch's combined action, the slider carries out reciprocating motion in the lead screw, the first riser that makes rises in turn, descend in turn after the translation, withdraw, the jacking massage effect of going on in cycles, effectively solved the patient and bedridden for a long time, some musculature is oppressed for a long time, especially back blood circulation is not smooth, easily leads to the production of bedsore.

Through jacking massage device, can also discharge patient's back and gather the heat, keep ventilating, avoid the patient to take place other unfavorable healthy situations such as prickly heat and appear, go up and down to combine horizontal massage extrusion action, increase local blood circulation of organism, attach audio player simultaneously, make the patient keep physical and mental joyful, can be fine let the patient relax, improve recovered efficiency.

The invention has simple structure and convenient use, can perform rehabilitation exercises of parts such as legs, ankles and the like, and can perform bending training on the legs of patients with fracture, thereby improving the recovery effect of the patients with fracture; aiming at the common long-term bedridden patient, the jacking massage movement device prevents the patient from bedsore in advance, so that the patient feels pleased in mind and body, and the use requirement of the user is met.
