Description

Technical Field

[0001] The utility model belongs to the technical field of medical rehabilitation equipment, and in particular relates to an osteoporosis rehabilitation device. Background Art

[0002] Osteoporosis is a systemic bone disease caused by a variety of reasons, which leads to decreased bone density and bone quality, destruction of bone microstructure, increased bone brittleness, and easy fracture. Osteoporosis can occur in different genders and at any age, but is more common in postmenopausal women and elderly men. It is characterized by bone pain and easy fractures.

[0003] For patients with osteoporosis, they need to actively participate in physical exercise by increasing outdoor activities and sunbathing. At different stages of rehabilitation, exercises of different intensities are required. When necessary, appropriate resistance and weight-bearing exercises can increase bone density and muscle strength more quickly and improve rehabilitation effects. However, most of the current osteoporosis rehabilitation devices can only exercise the limbs, and the patient's waist and back cannot be effectively exercised; and most of the current osteoporosis rehabilitation devices rely on the patient's active movement for exercise. For patients with osteoporosis in the initial stage, it is difficult for them to exercise on their own, and the inertia generated during exercise can easily cause physical injuries. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an osteoporosis rehabilitation device, which can effectively exercise the waist and back of patients and solve the problems of difficulty in exercise and easy sports injury in the initial stage of patients.

[0005] The content of this utility model includes:

[0006] A supporting torsion mechanism, the supporting torsion mechanism comprising a torque motor for providing a torsion action and a torsion platform rigidly arranged on the torque motor; and

[0007] An upper limb support and gripping mechanism is arranged adjacent to the support and twisting mechanism, and the upper limb support and gripping mechanism comprises a frame body and a gripping frame arranged on the frame body.

[0008] Optionally, the support and twisting mechanism further includes a lifter for adjusting the height of the twisting platform.

[0009] Optionally, the lifter is arranged at the bottom of the torque motor.

[0010] Optionally, the lifter is an electric lifting column.

[0011] Optionally, the osteoporosis rehabilitation device also includes a linear reciprocating drive platform for adjusting the distance between the supporting torsion mechanism and the gripping frame, the linear reciprocating drive platform includes a linear drive and a mounting plate arranged on the linear drive, and the supporting torsion mechanism is fixedly mounted on the mounting plate.

[0012] Optionally, the linear drive includes a linear guide rail, a drive motor, a lead screw connected to the drive motor, and a plurality of sliders arranged on the linear guide rail; the mounting plate is transmission-connected to the lead screw and fixedly connected to the slider.

[0013] Optionally, the linear guide rail is a double linear type and is located on both sides of the lead screw, and a slider is provided on the linear guide rail on each side.

[0014] Optionally, the upper limb support grasping mechanism also includes: a screw rod that is rotated on a fixed axis on the frame, a second drive motor that is connected to the top of the screw rod, and a double linear guide rail that is extended from top to bottom on the frame; the two ends of the grasping frame are slidably connected to the double linear guide rails, and the second drive motor drives the screw rod to drive the grasping frame to move up and down along the double linear guide rails for adjusting the height.

[0015] Optionally, the gripping frame includes a mounting frame, two handles rigidly connected to the mounting frame, and a crossbar disposed between the two handles.

[0016] Optionally, the torsion platform includes a supporting surface, a rib semi-surrounding the supporting surface, and a flexible layer adhered to the surface of the supporting surface and the inner side of the rib.

[0017] The beneficial effect of the utility model is that the patient can stand or sit on the twisting table, hold the gripping frame with both hands to stabilize the upper body, and drive the twisting table to twist back and forth by providing appropriate torque and rotation speed through the torque motor, so as to assist osteoporosis patients in the initial stage to twist the waist and back.

[0022] Compared with the prior art, the osteoporosis rehabilitation device provided by the utility model allows the patient to stand or sit on the twisting platform 12, holding the gripping frame 22 with both hands to stabilize the upper body, and the torque motor 11 provides appropriate torque and speed to drive the twisting platform 12 to twist back and forth, thereby assisting osteoporosis patients in the initial stage to twist their waist and back. The rotation angle of the torque motor 11 can be set, and the speed can be gradually reduced until it stops when approaching two extreme positions, so the probability of sports injuries to the patient can also be reduced. When the patient recovers for a period of time, the torque motor 11 can stop outputting power, and instead rely on the damping during the rotation of the torque motor 11 to strengthen the exercise.

[0023] In this embodiment, the support and twisting mechanism 10 further includes a lifter 13 for adjusting the height of the twisting platform 12. With such a configuration, the height of the twisting platform 12 can be adjusted according to the height of the patient, which is not only suitable for the patient's standing position and sitting state, but also allows the patient to step on the platform seat 16 or naturally hang the feet when the patient is in the sitting state, so that the patient can get exercises of different intensities and body parts.
