Description

Technical Field

[0001] This invention relates to medical rehabilitation equipment, specifically to a sports rehabilitation device for middle-aged and elderly people. Background Technology

[0002] Commonly used rehabilitation equipment for middle-aged and elderly people in clinical practice includes electric-assisted bicycles and walking aids. For example, electric-assisted bicycles are mainly suitable for people with some leg strength but who cannot yet stand independently. They primarily use electric assistance to passively move the affected limb with the healthy limb, promoting motor function in the affected limb and strengthening the quadriceps and hamstring muscles, as well as improving limb coordination to prevent muscle atrophy and joint contractures. Walking aids are suitable for rehabilitation users who can stand independently but cannot yet walk independently. At this stage, muscle strength has reached a certain level, and certain rehabilitation equipment is needed to assist walking. At this point, attention should be paid to limb coordination, walking posture, and overall muscle compensation during walking. Regular rehabilitation training under the guidance of a rehabilitation physician is recommended.

[0003] Different types of rehabilitation equipment have different functions and are suitable for different groups of people. Therefore, it is recommended that people who need rehabilitation training choose appropriate rehabilitation equipment according to their doctor's advice to achieve the desired rehabilitation training effect.

[0004] In clinical practice, some diseases such as stroke and brain injury can lead to hemiplegia. For hemiplegic patients, the training posture sequence should be supine, sitting, and standing, gradually enabling the user to achieve walking rehabilitation training. Traditional supine and sitting training usually involves changing the user's position by raising and lowering the upper part of the medical bed. Because the backrest of a conventional medical bed is hinged to the bed frame to create a flipping mechanism, and the axis of rotation of the human upper body in a supine position is centered on the hip joint, the axis of rotation of the backrest is located below and behind the hip joint rotation point during the backrest raising operation. Therefore, in current medical beds, the hip joint... The method only aims to ensure that the rotation axis of the hip joint is aligned with the rotation axis of the backrest by rotating close to the backrest. However, during actual operation, the body is in an eccentric state with the rotation of the medical bed as it rotates. Since the back of the body is in contact with the surface of the medical bed, pressure is applied to the hip joint and lumbar spine during the lifting and lowering process. Because the course of rehabilitation for walking is generally long, especially for elderly people, those with osteoporosis, hip joint injuries, or those who have undergone hip replacement, traditional rehabilitation training using a medical bed in supine or sitting positions can easily cause complications such as hip joint and lumbar spine strain. Summary of the Invention

Detailed Implementation

[0027] 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.

[0028] See Figures 1-7This embodiment discloses a sports rehabilitation device for middle-aged and elderly people, including an upper support 101 and a lower support 102. The lower support 102 has a left lifting seat 103 and a right lifting seat 104 on both sides. The upper support 101 includes a left arm 105 and a right arm 106, which are connected by a U-shaped frame 125. The left arm 105 is longitudinally hinged to a first hinge seat and rotatably mounted on the top of the left lifting seat 103 in a horizontal plane. The left arm 105 is equipped with a first electric rotating component driver that rotates around the hinge point. The right arm 106 is connected to the right lifting seat 104 via a first... A detachable fixing component is used for connection and fixation. The left arm 105 and right arm 106 are respectively connected to the swing arm 107 for fixing the arm. The lower support 102 is provided with swing footrests 108 on both sides to adapt to leg walking. The swing footrests 108 are fixed to the lower support 102 through a detachable structure. The bottom of the lower support 102 is provided with a roller module 109. The right arm 106 is provided with a second hinge seat and is connected to the second detachable fixing component and fixed to the edge of the bed. The left lifting seat 103 and the right lifting seat 104 are longitudinally slidably set on the lower support 102 through an electric sliding seat for longitudinal position adjustment.

[0029] This embodiment relates to a rehabilitation device for middle-aged and elderly people, which can be used for comprehensive rehabilitation training in supine, sitting, and standing positions. Compared with traditional rehabilitation equipment, this product is suitable for rehabilitation training in supine and sitting positions. Traditional supine and sitting positions use medical beds with backrest functions. To address the drawbacks mentioned in the background art, this product can be used by flipping the upper support 101 backward relative to the lower support 102, then sliding the lower support 102 to a suitable position, keeping the upper support 101 flush with the bed surface, and adapting the U-shaped frame 125 to the head and shoulders. The position of the lower support 102 and the lifting height of the left lifting seat 103 are adjusted so that the hinge point of the left arm 105 is adapted to the rotation position of the human hip joint. The right arm 106 is fixed to the other side of the bed through a second detachable fixing member. The two sets of hands of the person are adapted and fixed to the swing arms 107 on both sides. The first electric rotating component drives the upper limbs to be pulled up, as shown in the figure. The first electric rotating component includes a screw motor. The upper support 101 and the screw-slider 136 are configured with a screw motor 135 rotatably hinged to a rotating shaft connected to a first hinge seat. The screw-slider 136 is rotatably connected to the hinge point of the left arm 105. The screw-slider 136 and the screw motor 135 are threaded together, causing the screw motor 135 to rotate and drive the left arm 105 to rotate. Based on the rotation of the first electric rotating component, the user can be in a supine or sitting position. In this operation, the rotation axis of the upper support 101 is relatively aligned with the rotation axis of the upper limbs. During the back-raising process, the force on the hip joint and lumbar spine is small, which avoids damage to the hip joint and lumbar spine to a certain extent. In the supine and sitting positions, massage (manual massage or existing instrument massage) and leg flexion and extension or abduction and extension (manual assisted flexion and extension or abduction and extension or existing related instruments) can be performed to achieve initial rehabilitation training in the supine and sitting positions.

[0030] Especially for some leg rehabilitation programs, since they are in the standing rehabilitation training stage, and the initial standing rehabilitation training has certain requirements for hand strength, coordination, and lumbar spine, it can be adapted to leg rehabilitation training. Therefore, in this embodiment, the specific left arm 105 and right arm 106 include an upper arm 110 and a lower arm 111. The upper arm 110 is hinged to the corresponding left arm 105 and right arm 106 through a third hinge seat. The hinge shaft of the third hinge seat is equipped with a spiral spring for reset and pre-tensioning. The housing of the third hinge seat is fixed to the corresponding left arm 105 and right arm 106 through a detachable structure (fixed with bolts). The hinge shaft is connected to the corresponding The upper armrest 110 is fixed with a detachable structure (bolted). The lower armrest 111 is hinged to the upper armrest 110 and driven to rotate around the hinge point by a second electric rotating component (the second rotating component can be a servo motor, driving the upper and lower arms to flex and extend at a specific angle. When the servo motor is de-energized, the armrest and upper armrest 110 can rotate freely. Initially, the flexion and extension angle is adjusted using a servo motor, and later, it can be freely adjusted according to the user's actual movements of the upper and lower arms). The upper arm of the patient is adapted to the upper armrest 110 (as needed for the treatment course, a strap can be set on the upper armrest 110 for stability, and the same applies to the lower armrest 111). The lower arm is adapted to the lower armrest 111. Specifically, the lower armrest 111 is equipped with... A support plate 112 is laterally slidable on a groove of the upper boom 110 via a sliding shaft 113. The sliding shaft 113 is connected to an elastic reset part 114, which includes a fixed seat 115 and an elastic telescopic joint 116. The fixed seat 115 has multiple fixing positions 117 on the support plate 112. The elastic telescopic joint 116 is fixed to the sliding shaft 113. A handle 118 is provided at the front end of the support plate 112. The handle 118 is detachably fixed to the support plate 112. In this embodiment, the detachable structure of the handle 118 can adopt a threaded adapter plug-in structure, allowing for free adjustment during bending and extension. The user can perform flexion and extension movements by gripping the handle 118. In this structure, the hinge shaft of the third hinge seat is equipped with a spiral spring with a return preload. Initially, it is parallel to the corresponding left arm frame 105 and right arm frame 106. During the flexion and extension movements of the handle, the spiral spring can apply a certain force to the upper arm, which adapts to the back and forth swing of the upper arm and provides a certain force to train the arm muscles. The third hinge seat is connected to the left arm frame 105, right arm frame 106, and its corresponding upper arm frame 110 through a detachable structure, making it replaceable. The spiral spring of the third hinge seat can be adapted to different preload models and can be changed for training according to the user's arm rehabilitation cycle.

[0031] As an extension of the product's functions and an optimization of its performance, the two ends of the U-shaped frame 125 are hinged to the connecting rod and secured in position by fasteners (bolts). The connecting rod is slidably inserted into the left arm 105 and the right arm 106 and fixed by fasteners, allowing the U-shaped frame 125 to be flipped back and forth. The U-shaped frame 125 is equipped with a resistance traction device 133, which consists of a spiral spring connected to a traction line 134. The housing of the resistance traction device 133 is fixed to the bed frame or the side supports. The head end of the traction line 134 is fixed to the U-shaped frame 125 with a detachable bolt. The handle 118 is fixed to the U-shaped frame 125. By holding the column handle 118 with both hands, one can perform a forward flexion and downward cyclical pressing, thereby stretching and training the cervical spine and spine.

[0032] In this embodiment, the U-shaped frame 125 is specifically equipped with support shoulder plates 124 on both sides. The support shoulder plates 124 are connected and fixed by detachable parts. The support shoulder plates 124 are used for back support during the back-raising process. The method of use is to pre-fit the support shoulder plates 124 to the sides of the shoulders and back of the rehabilitation patient, and then press down the U-shaped frame 125 to fit and fix the shoulders. In this structure, the back can be supported during the back-raising process, which can provide some relief for patients in the early stages of rehabilitation who have insufficient arm strength or sitting strength, resulting in a large burden on the body and difficulty in maintaining the posture.

[0033] This structure can also be flipped back and fixed. For secure fixation, it can be additionally fixed to the left arm 105 and right arm 106 with bolts or fasteners. Since the U-shaped protrusion of the U-shaped frame 125 can be adapted to the middle part downward, the waist plate fixed at the U-shaped protrusion can support the waist. As mentioned above, it can be fixed in the opposite direction to continue to fix the two sides of the shoulders. This structure is designed to better adapt to the needs of different people. For example, during rehabilitation training in supine or sitting positions, since the rehabilitation user maintains a fixed position for a period of time, some rehabilitation users are prone to lumbar strain if they are not given lumbar support, which will affect the rehabilitation effect and may even aggravate the condition. Rehabilitation users can select the above-mentioned extended functions according to their actual needs. In this structure, the two sides of the U-shaped frame 125 are connected to the corresponding left arm 105 and the arm through a double-section telescopic structure and are fixed in position with fasteners. The length can be adjusted to adapt to the upper body height of different rehabilitation users.

[0034] In this embodiment, the U-shaped protrusion of the U-shaped frame 125 is adapted to a lumbar support plate 131. The lumbar support plate 131 is fixed to the U-shaped frame 125 by a fastener. The lumbar support plate 131 is adapted to a lumbar support plate 132. The lumbar support plate 132 is vertically slidable relative to the lumbar support plate 131 and fixed in position 117 by a limiting member. Compared with the structure of the shoulder support plate 124, the main function of this structure is to support the shoulders during the back-raising process, thereby reducing the lumbar support of the rehabilitation user. However, in the supine or sitting position, the shoulder support plate 124 alone cannot provide lumbar support, which can easily lead to lumbar muscle strain. Therefore, after the back-raising is completed, the lumbar support plate 131 is used to replace it, so that the rehabilitation user can better complete the rehabilitation course, reduce the risk of secondary injury or avoid prolonging the treatment course.

[0035] In this embodiment, the roller module 109 specifically adopts an electric drive wheel set or a universal wheel set, which can be detachably fixed by bolts. In the early stage, the electric drive wheel is used for assisted walking, and in the later stage, the universal wheel set can be used to autonomously push the support 102 for walking.

[0036] In order to adapt to the initial standing rehabilitation training, since the initial rehabilitation users do not have the ability to stand independently and need to rely on auxiliary support, in this embodiment, the U-shaped frame 125 is equipped with a hip fixation strap for binding and supporting the hips, which is used to bind and support the hips after getting out of bed, and to carry out leg rehabilitation training in sitting and standing positions.

[0037] In this embodiment, a swing leg bracket 108 is specifically provided. The swing leg bracket 108 includes a leg fixing member 119, a mounting base 120, a swing arm motor 121, a swing shaft 122, and a sliding block 123. The mounting base 120 is fixed to the base of the lower bracket 102. The swing arm motor 121 is fixed on the mounting base 120. The swing arm motor 121 is provided with a rotating swing arm rod 127. The swing arm rod 127 is hinged to the sliding block 123. The sliding block 123 is slidably sleeved on the swing shaft 122. The leg fixing member 119 includes a thigh fixing plate 128, a calf fixing plate 129, and a foot fixing plate 130. The foot fixing plate 130 is hinged to the calf fixing plate 129, and the hinge shaft is equipped with a spiral spring for initial position reset. The initial positions of the foot fixing plate 130 and the calf fixing plate 129 are perpendicular to each other. The calf fixing plate 129 and the thigh fixing plate 122 are perpendicular to each other. The 28-joint mechanism is equipped with a spiral spring for initial position reset. The thigh fixation plate 128 and the calf fixation plate 129 are initially parallel to each other. The thigh fixation plate 128 is rotatably mounted on the mounting base 120 via a shaft, which is fixed to the swing shaft 122. In this embodiment, a strap is provided on the leg fixation member 119 to bind the thigh, calf, and foot to the thigh fixation plate 128, calf fixation plate 129, and foot fixation plate 130, respectively. The swing arm motor 121 rotates to drive the thigh fixation plate 128 to swing, while the calf and foot swing autonomously with their limb axis. During the swinging process, the action of the spiral spring at the rotation axis needs to be overcome so that the muscles can be adapted and trained. In the product, the hinge component can be disassembled and installed. By replacing the spiral spring with different preload, different preloads can be obtained. The spring can be gradually replaced according to different treatment courses to achieve the purpose of gradual rehabilitation.

[0038] Because the swing leg 108 is installed with a detachable structure, the base of the lower support 102 can also be replaced with other types of walking exoskeleton equipment for adaptation, thereby achieving diversified expansion of rehabilitation functions. In this embodiment, the base of the lower support 102 has a U-shaped opening, which is used to enable rehabilitation users to walk independently without the swing leg 108 in the later stages, gradually completing subsequent rehabilitation training.

[0039] 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.
