Description

Technical Field

[0001] This invention relates to the field of rehabilitation therapy, specifically to a rehabilitation device for treating limb injuries caused by sitting posture in middle-aged and elderly people. Background Technology

[0002] Middle-aged and elderly people may require limb rehabilitation due to chronic diseases, arthritis, stroke, fractures, muscle atrophy, and other problems. These conditions can lead to limited motor function, weakened muscle strength, and decreased balance. Limb rehabilitation for middle-aged and elderly people may involve the use of various assistive devices, such as traction devices, to help restore or maintain independent mobility. Traditional traction devices use weights for traction, but in actual rehabilitation training, the following problems exist:

[0003] Unadjustable force and speed: During rehabilitation, a patient's muscle strength and coordination may vary significantly at different stages. Traditional weight-bearing traction equipment often cannot flexibly adjust the force and speed of the traction, which may result in applying excessive force to the patient in the early stages of rehabilitation, increasing the risk of injury.

[0004] Safety concerns: A rapid decrease in weight can increase the impact force during traction, especially for middle-aged and elderly individuals, potentially increasing the risk of injury. To address this issue, modern rehabilitation equipment employs smoother movement patterns to avoid sudden force impacts.

[0005] Rehabilitation assessment and adjustment: The rehabilitation process should be dynamic and individualized. Traditional equipment may not be able to provide effective rehabilitation assessment and adjustment throughout the entire rehabilitation course.

[0006] In conclusion, the design of modern rehabilitation equipment tends to address the potential problems of traditional traction equipment, providing a more flexible, safe, and personalized rehabilitation experience to better meet the rehabilitation needs of middle-aged and elderly people.

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0033] See Figures 1-7This embodiment discloses a rehabilitation device for treating limb injuries caused by sitting posture in middle-aged and elderly individuals. It includes a support body 101 and traction components 102. A set of traction components 102 is symmetrically arranged on both sides of the support body 101. Each traction component 102 includes a first lead screw motor 103, a support slider 104, a connecting seat 105, an adjusting seat 106, and a traction rope 107. The support slider 104 is threaded onto the lead screw of the first lead screw motor 103. A connecting... The connecting seat 105 has an electromagnet module 108 on its upper surface. A sliding column 109 is provided on the connecting seat 105. A permanent magnet is provided on the lower surface of the adjusting seat 106 and is slidably mounted on the sliding column 109. A pressure sensor is provided between the permanent magnet and the adjusting seat 106. One end of the traction rope 107 is fixed to the adjusting seat 106 and passes through the first guide wheel of the connecting seat 105 and several guide wheel groups 111 of the column of the support body 101 to the other end, which is fixed to the handle 112.

[0034] In this embodiment, during the traction process, the first lead screw motor 103 drives the support slider 104 up and down to achieve traction for the rehabilitation patient. The patient's autonomous muscle rehabilitation is achieved through the repulsive force between the electromagnet module 108 and the permanent magnet 110, creating a distance between them. During traction, on one hand, the patient's limbs move up and down with the movement of the support slider 104; on the other hand, force can be applied within the repulsive space between the electromagnet module 108 and the permanent magnet 110 to exercise the muscles. The force is adaptive, preventing significant drop and muscle strain even in the event of sudden release of force. The electromagnet module 108 and the permanent magnet 110... The repulsive distance can be gradually increased during the rehabilitation course to meet the needs of indirect rehabilitation. Simultaneously, since a pressure sensor is installed between the permanent magnet and the adjustment seat 106 in this structure, the pressure sensor will change its value during the application of additional traction force, thus quantifying the traction force and providing a concrete visual reference during the rehabilitation course. Furthermore, since pressure values ​​are set on both sides, the pressure values ​​on both sides can be compared during traction. During rehabilitation training, by controlling the force, the pressure values ​​can be varied within the same range, ensuring that the forces on both sides are as balanced as possible. This has a positive effect on the coordination of both limbs, effectively improving the rehabilitation effect. If incoordination is found, targeted rehabilitation exercises can be performed.

[0035] Meanwhile, in this embodiment, conventional weight-bearing exercises can also be performed in later training sessions. Specifically, the support body 101 is provided with a guide shaft 113, and the limiting plate fixed at the top of the sliding column 109 is slidably disposed on the guide shaft 113. A sleeve is provided on the limiting plate for a detachable counterweight 114. The counterweight 114 is composed of two sets of semi-circular components, one end of which is hinged, and the other end is provided with a locking device that is fixed to each other. At this time, after the support slider 104 slides to the bottom, the connection lock between the support slider 104 and the connecting seat 105 can be unlocked, and the electromagnet module 108 will not work or will be attracted to the permanent magnet 110. At this time, the counterweight 114 can be installed on the sleeve to realize traditional up and down pulling, which meets the needs of normal muscle training and maintenance in the later stages.

[0036] In this embodiment, the adjusting seat 106 is provided with a roller module 115 for winding and unwinding the cable. The other end of the traction rope 107 is provided on the roller module 115. The roller module 115 is driven by a motor with a locking function and is used to adjust the range according to the different height requirements of the user. The upper end surface of the electromagnet module 108 is provided with an annular mounting groove 116. A buffer spring 117 is fixed in the mounting groove, protruding from the surface of the electromagnet module 108, for buffering the downward movement of the adjusting seat 106.

[0037] In this embodiment, the handle 112 includes a fixed body 118, which has four sets of secondary grooves 119. Each secondary groove 119 has an arc-shaped groove 120 for accommodating four fingers (excluding the thumb). At least one set of secondary grooves 119 is connected to the fixed body 118 via a press-adjustment switch, which is connected to a controller for adjusting the power of the electromagnet module 108. The other three sets of secondary grooves 119 are slidably mounted on the fixed body 118 via springs 122. A main groove 121 is positioned at the thumb adaptation location and is slidably mounted on the fixed body 118 via springs 122. The main groove 121, secondary grooves 119, and fixed body 118 are all adapted to... The device includes straps for securing the fingers and palm in their positions. On one hand, during traction, the spring 122 helps rehabilitate the fingers' gripping ability. On the other hand, as the rehabilitation progresses and gripping ability strengthens, the muscle strength of the arm gradually recovers. Therefore, one set of arc-shaped grooves 120 is connected to a pressure adjustment switch, which is connected to a controller to adjust the power of the electromagnet module 108. The higher the gripping progress, the larger the repulsion range. Thus, the force can be adjusted during movement to meet the patient's needs for traction resistance in different areas during traction. The pressure adjustment switch can be turned on or off, depending on the needs of the rehabilitation patient.

[0038] In this embodiment, the support body 101 is also provided with an electrode driving module. The electrode driving module is provided with multiple sets of electrode connection ports 123. The electrodes can be attached to the surface of various areas of the limb through the lead wire connection ports 123, so as to realize muscle and nerve rehabilitation through electrode stimulation in the early stage of rehabilitation.

[0039] Given that different patients have different shoulder widths and limb lengths during traction, and that vertical traction rehabilitation at a single position cannot adequately train the joints and surrounding muscles during the up-and-down traction process, in this embodiment, the guide wheels at the top of the plurality of guide wheel groups 111 are mounted on the support rod 124. The rear end of the support rod 124 is rotatably mounted on the support body 101. The front end of the support rod 124 is provided with a rotation track groove 125 and is slidably mounted on the track groove 125 by a connecting slider. The support rods 124 on both sides are provided with a pushing device, which includes a second lead screw slider mechanism 126. The lead screw slider mechanism 126 has adjusting rods 127 on both sides. One end of the adjusting rod 127 is hinged to the lead screw slider, and the other end is hinged to the support rod 124. By swinging the support rod 124, the position of vertical traction can be adjusted, thereby meeting the needs of different patients with different shoulder widths and limb lengths, and allowing traction at multiple positions to adequately train the joints and surrounding muscles.

[0040] In this embodiment, the mounting base of the support body 101 is provided with a seat 128. The seat 128 is slidably mounted on the base of the support body 101 and driven by a third lead screw mechanism 129. The front end of the seat 128 has a leg support portion, which consists of a thigh support portion 130, a calf support portion 131, and a foot support portion 132. The thigh support portion 130 is slidably mounted longitudinally on the front side of the seat 128 and secured with fasteners. The thigh support portion 130 and the calf support portion 131 are hinged and their angle is adjusted by a drive motor. The foot support portion 132 is slidably mounted longitudinally on the calf support portion 131 and is driven by a fourth lead screw mechanism 33 to slide up and down. The tilt is adjusted by the calf support portion 131, and leg raising training is achieved by the up-and-down movement of the foot support portion 132.

[0041] The front end of the support body 101 is provided with a human-computer interaction screen 134, which is used to provide training videos, pressure display, selection of training modes, and adjustment of training parameters.

[0042] The above description is merely illustrative of the invention. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined by the claims, all of which should fall within the protection scope of this invention.
