Description

Technical Field

[0001] The present invention relates to the technical field of daily movement assistance and rehabilitation exercise training for patients with lower limb dysfunction, and particularly relates to a sit-to-stand movement rehabilitation training device. Background Art

[0002] With the aggravation of the problem of social aging in China, the number of the elderly and elderly patients with lower limb motor dysfunction is increasing year by year; since the lower limb muscles of such patients cannot provide sufficient power required for movement, the risk of injury is often increased due to difficulty or failure in standing up; to meet the growing needs of such people for a better life, it is particularly important to provide movement assistance and rehabilitation exercise training during the healthy and safe sitting, standing, and walking processes, which requires providing flexible and convenient weight support to patients during the standing-up and walking processes to ensure safe and effective training of the lower limb muscle groups to achieve the ultimate goal of movement rehabilitation.

[0003] Regular and scientific rehabilitation assistance training combined with appropriate medical assistance devices is very effective in restoring and improving the lower limb sit-to-stand conversion function, and can effectively help patients recover their restricted limb functions and improve their daily living abilities. Traditional sit-to-stand function training products mostly rely on the assistance of therapists, and there is no instrument guidance throughout the training process. Moreover, adult patients have a large body weight, so the physical consumption of the assisting personnel during the training process is huge, and at the same time, patients are more likely to have accidental injuries; at the same time, effective fixation and rehabilitation exercises cannot be carried out for patients of different body types; among the products that can provide assistance on the market currently, some require patients to have relatively high muscle strength in the lower limbs or require the patients to actively provide auxiliary force with the upper limbs, thus limiting the user population. Some devices have no support mechanism behind, so patients cannot rely on for rest after long-term exercise, which increases the physical consumption of patients and will bring great discomfort to patients; at the same time, when changing the sit-to-stand posture, most devices do not have a limit restraint mechanism to restrain the forward posture when the patient changes the posture, so that the patient is prone to fall forward or fall left and right during the posture change process, causing harm to the patient.

[0004] Therefore, in order to solve the above problems, this article proposes a sit-to-stand movement rehabilitation training device. Summary of the Invention

[0005] The purpose of the present invention is to design a sit-to-stand movement rehabilitation training device that can be applicable to patients of different body types and heights, can provide movement guidance during the exercise process, can provide auxiliary support for the lower limbs of patients, can provide a force to rely on when the patients are fatigued, and can provide protection for the patients during the posture change process.

[0006] To achieve the above technical effects, the present invention is realized through the following technical solutions: A sit-to-stand motion rehabilitation training device, comprising a moving frame, a support device, and a lifting device; the bottom of the moving frame is provided with a bottom plate, the bottom end of the bottom plate is provided with universal wheels with brakes and footrests, a push rod fixedly installed at one end of the bottom plate, a control mechanism fixedly installed on the upper surface of the bottom plate, and an adjustable guardrail; the support device includes a lifting mechanism fixedly installed on the upper surface of the bottom plate, a support seat fixedly connected to the output end of the lifting mechanism, and support mechanisms arranged on both sides of the support seat; the lifting device includes a sliding frame fixedly connected to the upper surface of the side end of the bottom plate, sliding grooves arranged on both sides of the sliding frame, a backrest connected to the inside of the sliding grooves, covering mechanisms with ends that can cooperate and connect with each other arranged on both sides of the backrest, and a lifting mechanism fixedly installed on the top of the sliding frame.

[0007] The lifting mechanism includes a lifting frame fixedly installed on the top of the sliding frame, a rack arranged on the top of the lifting frame, a sliding block meshing with the external rack of the lifting frame, a sliding motor fixedly installed on the top of the sliding block, a telescopic frame fixedly connected to the bottom of the sliding block, a fixing block arranged in the middle of the telescopic rod of the telescopic frame, a boosting frame rotatably connected to the end of the telescopic frame, and a lifting rod fixedly connecting the fixing block and the boosting frame; the sliding motor is electrically connected to the control panel; both the telescopic frame and the lifting rod are connected to the hydraulic mechanism through oil pipes.

[0008] Furthermore, the control mechanism includes a control box fixedly installed on the upper surface of the bottom plate, a hydraulic mechanism and a battery installed inside the control box, a control panel fixedly installed on the top of the control box, and a power cord arranged on the side end of the control box.

[0009] Furthermore, the control panel is internally provided with a control unit, a timer, and an alarm, and its outer surface is provided with a display screen and adjustment knobs; both the battery and the power cord are electrically connected to the control panel.

[0010] Furthermore, both the footrest and the lifting mechanism are connected to the hydraulic mechanism through oil pipes.

[0011] Furthermore, the top of the support seat is in an arc-shaped structure; a soft pad is arranged on the outer surface of the support seat.

[0012] Furthermore, the support mechanism includes rotating parts fixedly installed on both sides of the support seat, thigh support rods and calf support rods rotatably connected to both sides of the rotating parts, foot sleeves fixedly installed at the bottom of the calf support rods, and multiple groups of length-adjustable and end-interfitting connection restraint mechanisms arranged at equal intervals on both sides of the thigh support rods, calf support rods, and foot sleeves.

[0013] Furthermore, the backrest includes a slider connected to the inside of the sliding groove by the sliding groove, an elastic band fixedly connected to the outer side wall of the slider, a backrest pad fixedly connected to the end of the elastic band, and connection blocks arranged on both sides of the backrest pad and located on the covering mechanism.

[0014] Further, locking mechanisms that cooperate with the connection blocks are symmetrically arranged on both sides of the assist frame near the sliding frame end.

[0015] Another object of the present invention is to provide a method for using a sitting and standing motion rehabilitation training device, which is characterized in that:

[0016] S1. Before use, the assisting personnel need to move the device to a suitable position, then connect the power cord to an external power source, operate the control panel to turn on the device, and then operate the control panel to control the hydraulic mechanism to act, further causing the footrest to act and support and fix the device; complete the movement and fixation of the device.

[0017] S2. After the device is fixed; the assisting personnel control the support mechanism to rise or fall through the control panel according to the body type and height of the patient using the device, so that the height of the support seat meets the requirements of the body type and height of the patient using the device; at the same time, control the sliding motor to move the sliding block to a suitable position on the lifting frame, so that when the patient using the device changes the sitting and standing postures, the lifting rod and the assist frame cooperate to meet the required movement trajectory when the patient using the device stands; when the position of the sliding block is fixed, control the telescopic frame to act through the control panel to raise or lower the assist frame so that it meets the requirements of the body type and height of the patient using the device; complete the determination of the positions of the support seat and the assist frame.

[0018] S3. At this time, set the action rate of the lifting rod, the length of the single standing time, the time interval between two standings, the total training duration, the single maximum stroke, and the alarm stroke through the control panel; complete the initial parameter setting of each component before training.

[0019] S4. During use, with the assistance of the assisting personnel, help the patient using the device to sit on the support seat, and then manually adjust the height of the guardrail so that the patient using the device can place their hands on the top of the guardrail to gain leverage and place them; at this time, the assisting personnel will fix the patient's thigh, calf, and foot on the outside of the thigh support rod, calf support rod, and foot sleeve in sequence through the restraint mechanisms symmetrically arranged on both sides of the support seat, then move the backrest to a suitable position, and then combine the patient's waist and back with the backrest through the covering mechanism; then control the telescopic frame and the lifting rod to act through the control panel to move the assist frame to a suitable position, and then connect the locking mechanism and the connection block; maintain the use and wearing of the device.

[0020] S5. At this time, the patient controls the movement speed and stroke length of the lifting rod through the control panel. When the lifting rod is controlled to extend, the assisting frame moves in a parabolic motion inclined upward, enabling the patient to change from a sitting position to a standing position. During this process, the assisting frame and the backrest cooperate to provide a movement guide for the posture change from sitting to standing. When the standing time reaches the single standing time set in advance, the control panel automatically controls the lifting rod to shorten, causing the assisting frame to move in a parabolic motion inclined downward. During this process, the elastic band of the backrest and the backrest cooperate to provide a movement guide for the posture change from standing to sitting.

[0021] S6. When the time reaches the interval between two standing times, the control panel automatically controls the lifting rod to perform the conversion between sitting and standing postures. At this time, repeating the process of mutual transformation between standing and sitting postures in step S6 can exercise the patient.

[0022] The beneficial effects of the present invention are as follows:

[0023] (1). By setting an adjustable lifting mechanism, a support mechanism, a telescopic frame, a lifting rod, and a chute on the sliding frame, and connecting the backrest chute to the inside of the chute, the device can be applicable to patients of different heights. During use by different patients, corresponding adjustments can be made according to specific requirements to meet the required assistance change positions for posture changes of patients of different body types.

[0024] (2). By setting a sliding block that can change its position on the lifting frame, a restraint mechanism and a covering mechanism with adjustable lengths and mutually cooperating ends, and an adjustable locking mechanism, the device can be applicable to patients of different body types and meet the required assistance change positions for posture changes of patients of different body types.

[0025] (3). By setting a battery and a power cord, it can be connected to an external power source when an external power source exists to supply power to the device. When there is no external power source or a power outage occurs, the battery can actively supply power to each component for a period of time, enabling the device to continue working.

[0026] (4). By setting a lifting mechanism and an elastic band connecting the backrest to the sliding frame, the lifting mechanism provides a certain guiding force for traction when the patient changes from a sitting posture to a standing posture, achieving an accurate posture change. The backrest restrains the patient's waist and back, and the backrest moves along the chute of the sliding frame. At this time, the elastic band connecting the backrest to the sliding frame can provide a certain guiding force for traction when the patient changes from a standing posture to a sitting posture, achieving an accurate posture change.

[0027] (5) By providing a backrest and a support mechanism, the backrest can provide a certain amount of support for the patient when sitting, while protecting the patient's lumbar and dorsal regions. When the patient changes from a sitting to a standing position, the backrest cushion follows the patient's movement to restrict the overall posture of the patient's lumbar and dorsal regions and prevent the patient's waist from being sprained. The support mechanism restricts and positions the patient's thighs and calves, and at the same time provides a certain degree of auxiliary support for the patient's legs when the patient changes from a sitting to a standing position, reducing the pressure on the patient's legs. This prevents the patient's legs from being damaged due to inability to bear the pressure during posture change, further preventing the patient from falling and causing damage to other parts of the patient.

After the device is fixed; the assisting personnel control the support mechanism (23) to rise or fall through the control panel (154) according to the body type and height of the patient using the device, so that the height of the support base (22) meets the requirements of the body type and height of the patient using the device; at the same time, control the sliding motor (354) to move the sliding block (353) to a suitable position on the lifting frame (351), so that when the patient using the device changes the sitting and standing postures, the lifting rod (358) and the power-assisted frame (357) cooperate to meet the required movement trajectory when the patient using the device stands; when the position of the sliding block (353) is fixed, control the telescopic frame (355) to act through the control panel (154) to raise or lower the power-assisted frame (357) to meet the requirements of the body type and height of the patient using the device; complete the determination of the positions of the support base (22) and the power-assisted frame (357). S3. At this time, set the action rate of the lifting rod (358), the length of the single standing time, the time interval between two standings, the total training duration, the single maximum stroke, and the alarm stroke through the control panel (154). Complete the initial parameter setting of each component before training. S4. During use, with the assistance of an assistant, help the patient to sit on the support seat (22). Then manually adjust the height of the guardrail (16) so that the patient can place their hands on the top of the guardrail (16) for leverage and placement. At this time, the assistant will use the restraint mechanisms (235) symmetrically arranged on both sides of the support seat (22) to fix the patient's thighs, calves, and feet to the outside of the thigh support rod (232), calf support rod (233), and foot sleeve (234) in sequence. Then move the backrest (33) to a suitable position, and then combine the patient's waist and back with the backrest (33) through the covering mechanism (34). Then control the telescopic frame (355) and the lifting rod (358) to move the assist frame (357) to a suitable position through the control panel (154), and then connect the locking mechanism (359) and the connecting block (334). Maintain the use and wearing of the device. S5. At this time, the patient uses the control panel (154) to independently control the action rate and stroke length of the lifting rod (358). When controlling the lifting rod (358) to extend, the assist frame (357) moves in a parabolic motion inclined upward, realizing the transformation of the patient from a sitting position to a standing position. During this process, the assist frame (357) and the backrest (33) work together to provide a motion guide for the posture transformation from a sitting position to a standing position. When the standing time reaches the previously set single standing time; the control panel (154) automatically controls the lifting rod (358) to shorten the lifting rod (358), making the assist frame (357) move in a parabolic motion inclined downward. During this process, the elastic band (332) of the backrest (33) and the backrest (33) work together to provide a motion guide for the posture transformation from a standing position to a sitting position. S6. When the time reaches the interval between two standing times, the control panel (154) automatically controls the lifting rod (358) to perform the conversion between the sitting position and the standing position; at this time, repeat the process of mutual transformation between the standing position and the sitting position in step S6 to exercise the patient.
