Description

A sit-stand training device that provides sit-stand support feedback Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a sitting-standing training device that provides sitting-standing support feedback. Background Technology

[0002] For hemiplegic patients, their center of gravity tends to shift to one side when sitting down and standing up, requiring manual intervention for correction. The origins of sit-to-stand training devices can be traced back to the late 20th century, when people began to realize the impact of a sedentary lifestyle on health. With technological advancements and increased health concerns, some basic sit-to-stand transition devices emerged, primarily designed to help users switch between different postures to reduce the stress of maintaining the same position for extended periods. In the 21st century, the rapid development of sensor technology, electronic technology, and control theory has greatly improved the design and functionality of sit-to-stand training devices. The introduction of advanced technologies such as pressure sensors and posture detectors allows devices to more accurately determine the user's posture and provide personalized feedback and suggestions. With the fast pace of modern life and increased work pressure, maintaining the same posture for extended periods has become the norm for many. This leads to a series of health problems, such as lower back pain and neck pain. Therefore, the public's demand for sit-to-stand training devices is increasing to help them improve their posture and overall health. With growing environmental awareness, the design of sit-to-stand training devices has also begun to consider energy conservation and environmental factors. For example, some devices utilize renewable or recyclable materials and energy-efficient electronic components. Furthermore, some advanced devices feature energy recovery capabilities, collecting and reusing energy as the user changes posture. The development and historical context of sit-to-stand training devices providing support feedback is the result of multiple factors. It reflects not only technological advancements and increasing health needs but also people's focus on environmental protection and energy conservation. In the future, with further technological development and evolving social needs, the design and functionality of sit-to-stand training devices will continue to be improved and innovated.

[0003] Currently, Chinese patent CN110051976A discloses a sensorimotor integrated cushion and its usage method. It includes a plate-shaped base and a cushion, with the cushion positioned above the base. A support frame, a hollow box, is located at the center of the cushion's bottom surface. The upper end of the support frame is fixedly connected to the cushion, and an opening is provided on the side of the support frame. An inclination sensor is installed inside the support frame, and the sensor has a data interface for connecting a data cable and external hardware, with the data interface facing the opening on the side of the support frame. The bottom of the support frame is connected to the base via a universal coupling. Return springs are evenly distributed around the support frame, with their ends connected to the base and the cushion respectively. In its natural state, the cushion remains horizontal. While this sensorimotor integrated cushion and its usage method have a simple structure, they cannot monitor the patient's standing position, thus limiting their practicality. Furthermore, when performing posture correction and lumbar spine training while seated, if the patient's posture or lumbar spine is not yet capable of independent training, support and protection for the patient's upper body are required. This patent lacks such a protective device. Finally, during the standing process, if the patient's legs are not strong enough to support them to complete the training independently, then equipment is also needed for assistance, which is not included in this patent, thus posing a significant safety hazard. Summary of the Invention

[0004] (I) Technical Problems Solved: Addressing the shortcomings of existing technologies, this invention provides a sitting-standing training device that offers feedback on sitting and standing support. It can detect the patient's lateral swaying during standing in real time, allowing for further analysis of training focus. It effectively provides protection during sitting posture and lumbar spine lateral swaying training. During standing, the coordinated operation of various components also protects the patient, reducing safety hazards. This solves the problem of traditional sitting-standing training devices with sensorimotor integration, which have simple structures but cannot monitor the patient's standing state, resulting in poor practicality. Secondly, during sitting posture correction and lumbar spine training while seated, if the patient's sitting posture or lumbar spine is not yet capable of independent training, support and protection for the upper body are required, which existing devices lack. Finally, during standing, if the patient's legs are insufficient to support them independently, assistance is also needed, which is also absent in existing devices, thus posing significant safety risks.

[0015] (III) Beneficial Effects: Compared with the prior art, the present invention provides a sitting-standing training device that provides sitting-standing support feedback, which has the following beneficial effects: 1. This sitting-standing training device that provides sitting-standing support feedback uses a bracket, a cushion, a standing support frame, and a standing clamp in cooperation. During the analysis and protection of the patient's standing process, the patient is first allowed to sit on the cushion. At this time, due to the positioning arc surface set on the cushion, the patient's buttocks can automatically slide to the center position of the cushion, ensuring the patient's correct position, which is beneficial for subsequent detection. Then, the patient's feet are placed in the foot fixing seat and positioned in the center. Finally, the clamp is pulled up, causing the card to disengage from the toothed protrusion of the slide rod, and then the standing support frame is pushed to the patient's chest. The clamp motor is activated so that the clamp grips the patient's chest. At this time, the patient can perform standing status detection and training. When the patient stands, his left and right feet exert a downward force on the pedal. At this time, the force of the left and right feet on the pedal is transmitted to the pressure sensor two through the second spring. First, for a single foot, each pressure sensor in the outer frame generates a pressure value, detecting the force on the foot in four directions and thus the force difference. Second, for both feet, the pressure sensors in the two footrests aggregate the pressure values, producing two pressure values ​​for the left and right feet. Analyzing these two pressure values ​​reveals the force difference and directional deviation between the left and right feet. During standing, the patient's chest moves forward, causing the standing clamp in front of the chest to move forward. If the patient's upper body sways from side to side during standing, this further causes the left and right swing arms to swing. When the swing arms swing left and right, they generate a force on the two third springs on the sides, which in turn transmit this force to the pressure sensor at the end, thus detecting the swaying of the body during standing. This detection is linear, monitoring the swaying of the body in real time throughout the entire standing process, ultimately producing a graph showing the relationship between time and the force of the swaying, allowing for better analysis and targeted training. This achieves the effect of real-time detection of the patient's swaying during standing, further enabling analysis of training priorities.

[0016] 2. This sitting-standing training device provides feedback through the coordinated use of a seat cushion, a traction magnetic module, magnetic protective claws, and a rotary motor. When the patient only needs to perform sitting correction or lumbar training, they simply need to sit in the center of the base. If the patient is not in the exact center, the positioning arc surface on the base will automatically slide the patient's buttocks towards the center, positioning them there. Once the patient is in the center, the posture is adjusted. If the patient is tilted, the force exerted by their upper body on the base is not vertical, compressing the first spring beneath the base. This compressed spring exerts pressure on a pressure sensor, which records the pressure. By analyzing the four values ​​recorded by the four pressure sensors on the upper base, the patient's upper body center of gravity shifts, allowing for posture adjustment. Secondly, during lumbar twisting or swaying training, protection is provided by first protecting the patient's waist by using electromagnetic... When the electromagnet is activated, it attracts the electromagnet to the curved magnetic plate behind it. Once they are attracted together, the rotating motor is turned on, causing the rotating shaft to rotate and pull the curved magnetic plate towards the patient's waist. When the magnetic protective claws on both sides are in full contact with the patient, the current in the electromagnet reverses, creating a repulsive force between the electromagnet and the curved magnetic plate. At this point, the rotating motor stops rotating, the rotating shaft is fixed, and a magnetic space is formed between the magnetic protective claws and the curved magnetic plate. This allows the patient to perform left-right twisting or swaying exercises of the waist while the magnetic protective claws provide protection, and also provides sufficient space for training. This effectively provides protection during seated posture exercises and lumbar spine swaying exercises.

[0017] 3. This sitting-standing training device provides feedback through the coordinated use of a support frame, a standing support frame, and a standing clamp. During the standing process, most patients undergoing rehabilitation training may experience insufficient lower limb strength or tilting after standing, posing a safety hazard. The standing clamp at the chest, via a clamp motor, keeps the clamp's jaws firmly gripping the patient's chest. The jaws are mounted on the upper crossbar through a third mounting hole and only slide left and right, not rotating. Therefore, the jaws provide protection if the patient loses balance. Furthermore, the elastic coefficient of the third spring can be adjusted via a threaded sleeve. For patients who are overweight or experience excessive lateral swaying during standing, a greater elastic force is needed for better protection. The length of the third spring can be adjusted by rotating the threaded sleeve, thereby changing the elastic force to better protect overweight patients or those with large swaying amplitudes. This achieves the effect of protecting the patient during standing through the coordinated action of various components, reducing safety hazards. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Embodiments

[0021] Please refer to Figures 1-13. A sit-to-stand training device providing sit-to-stand support feedback includes a support frame 1 and a seat cushion 2. The support frame 1 includes an upper seat plate 11, guide crossbars 13, and side bars 15. Two side bars 15 are arranged below the upper seat plate 11 and connected by a vertical rod. Two guide crossbars 13 are arranged between the two side bars 15, and the guide crossbars 13 are perpendicular to the side bars 15. The guide crossbars 13 and side bars 15 provide stable structural support, ensuring the stability and load-bearing capacity of the standing training device. The guide crossbars 13 ensure that the standing support frame 4 can move accurately and stably. The standing support frame 4 provides support to the user during standing and moves back and forth through wheels 44, providing dynamic support feedback to the user. The cooperation of the sliding rod 45 and the toothed protrusions ensures the positioning accuracy and stability of the standing support frame 4.

[0022] A guide hole 132 is provided on the side of the guide crossbar 13. The guide hole 132 determines the movement range and stability of the standing support frame 4. A suitable size ensures the smooth sliding of the slide bar 45, while a suitable length ensures the stability of the standing support frame 4. The standing support frame 4 is assembled in the guide hole 132. The standing support frame 4 includes a vertical support rod 41, a third spring 42, and a slide bar 45. The slide bar 45 is slidably assembled in the guide hole 132. The length of the slide bar 45 determines the maximum movement distance of the standing support frame 4. One end of the slide bar 45 is fixedly connected to the bottom of the standing support frame 4. The slide bar 45 is provided with toothed protrusions. The cooperation between the toothed protrusions and the slide bar 45 determines the positioning accuracy and stability of the standing support frame 4, and the cooperation between the toothed protrusions and the card 135 can control the forward and backward movement of the standing support frame 4. The vertical support rod 41 has an upper horizontal bar 46 at its upper end, and wheels 44 are respectively installed at the bottom of the vertical support rod 41. The wheels 44 allow the standing support frame 4 to move more easily when pushed out. A standing clamp 5 that can slide left and right is installed in the middle of the upper horizontal bar 46. Third springs 42 are installed on both sides of the standing clamp 5 on the upper horizontal bar 46. The function of the third springs 42 is to provide elastic force to ensure that the standing clamp 5 can accurately detect the swaying of the body and provide real-time feedback. A pressure sensor 43 is installed at the end of the upper horizontal bar 46 near the third spring 42. The pressure sensor 43 is used to detect the left and right swaying of the body during standing. Its range and accuracy directly affect the performance of the training device. The pressure sensor 43 detects the left and right swaying of the body during standing in real time and transmits the data to the control system for real-time analysis to help users better understand their posture and movements. The standing clamp 5 includes left and right swing arms 51 and grippers 52. The left and right swing arms 51 are mounted on the upper crossbar 46. One end of each swing arm 51 is equipped with a rotatable gripper 52. A clamp motor 53 is located at the bottom of the gripper 52. The clamp motor 53 drives the gripper 52 to move. Its power and torque determine the clamping force and speed of the gripper 52. The gripper 52 and clamp motor 53 provide the user with front-to-back balance support and protection during standing. The clamp motor 53 drives the gripper 52 to ensure that the gripper 52 is always in close contact with the user's chest, providing stable support.

[0023] The left and right swing arms 51 are provided with at least three evenly distributed third mounting holes 511. Multiple mounting holes can be used to accommodate patients of different body types. The third mounting holes 511 cooperate with the upper crossbar 46. The upper crossbar 46 is provided with at least four locking keys 461. The third mounting holes 511 are provided with the same number of locking slots as the locking keys 461. The cooperation between the locking keys 461 and the locking slots allows the standing clamp 5 to slide left and right but not rotate, thus providing front-back support for the patient during the subsequent standing process.

[0024] An assembly hole 131 is provided above the guide hole 132. A retaining plate 133 is fitted into the assembly hole 131 and can rotate within it. A card 135 is connected to the lower part of the retaining plate 133 via a fourth spring 134. When the patient stands up, the standing support frame 4 is pushed forward. At this time, since the card 135 and the protrusion on the slide rod 45 are aligned, the card 135 can be easily pushed out. When the standing support frame 4 needs to be pushed to the patient's chest, the retaining plate 133 needs to be rotated upward to disengage the card 135 from the protrusion, allowing the slide rod 45 to slide smoothly within the guide hole 132.

[0025] One end of the side rod 15 is provided with a foot fixing seat 3. The foot fixing seat 3 includes an outer frame 31 and a pedal 32. The outer frame 31 is rectangular and box-shaped, providing a stable structure to fix the user's foot, ensuring the stability and load-bearing capacity of the foot fixing seat 3. The design of the outer frame 31 should ensure foot comfort and stability. The bottom of the outer frame 31 is provided with through holes distributed at the four corners. Pressure sensors 311 are provided on the surface of the through holes. The through holes and pressure sensors 311 detect the force of the foot in real time and transmit the data to the control system for real-time analysis, helping the user better understand their force and movement. The design of the through holes allows the pedal 32 to act on the second spring 322, which in turn acts on the pressure sensor 311. The bottom of the pedal 32 is provided with a second mounting shaft 321 corresponding to the through holes. The second mounting shaft 321 is provided with a second spring 322. The second spring 322 provides feedback to the user when the foot applies force, ensuring that the pedal 32 can act accordingly based on the force of the foot, providing the user with a real-time feedback mechanism. The second spring 322 provides a linear, real-time feedback mechanism to help users better control the force and movement of their feet. The pedal 32 is slidably fitted into the outer frame 31 via the second mounting shaft 321. This slidable fit ensures the pedal 32 is fixed within the outer frame 31, allowing it to respond appropriately to the force applied by the foot, providing stable support and feedback to the user. The design of the pedal 32 should ensure both stability and comfort.

[0026] The upper seat plate 11 has through holes machined at its four corners, and pressure sensors 12 are mounted on the upper surface of the through holes. A first mounting hole 14 is provided on the rear side of the upper seat plate 11. The upper seat plate 11 provides weight-bearing support for the user's sitting posture, ensuring the stability and load-bearing capacity of the training device. The design of the upper seat plate 11 should ensure its load-bearing capacity and comfort. The through holes and pressure sensors 12 detect the pressure distribution on the upper seat plate 11 in real time and transmit the data to the control system for real-time analysis, helping the user better understand their sitting posture and stress conditions. The first mounting hole 14 is used for connection with the rotating shaft 81.

[0027] The upper seat plate 11 is covered with a seat cushion 2, which includes a base 21. The base 21 is a box-shaped structure with an opening at the bottom and a hollow interior. The base 21 provides the basic structure for the seat cushion 2, ensuring its stability and load-bearing capacity. The design should consider the physiological characteristics of human sitting posture to ensure comfort. The upper surface of the base 21 is provided with a positioning arc surface 22, which is lower in the middle and gradually rises on both sides. The positioning arc surface 22 allows the seat cushion 2 to better conform to the curve of the buttocks, improving the comfort of sitting posture. The design should consider the shape and size of the human buttocks and allow the patient to automatically slide to the center position of the seat cushion 2 for subsequent testing. The base 21 is also provided with a central rod 23, which is used to install the magnetic protective claw 7. A second mounting hole 26 is provided behind the central rod 23 for connection with the rotating shaft 81. The base 21 has four first mounting shafts 24 distributed at its four corners. These first mounting shafts 24 correspond to through holes on the upper seat plate 11. Each first mounting shaft 24 has a first spring 25 mounted on it. The first mounting shafts 24 and the first springs 25 ensure that the seat cushion 2 can be stably mounted on the base 21 and provide a certain degree of elasticity, offering better support and comfort for the user. The first springs 25 provide elastic feedback, helping the user better control their posture and pressure distribution.

[0028] Magnetic protective claws 7 are sequentially arranged on the central rod 23. Each magnetic protective claw 7 includes an arc-shaped cushion frame 72 and an electromagnet 73. The arc-shaped cushion frame 72 provides the basic structure and shape of the magnetic protective claw 7, ensuring its fit and comfort against the patient's back and waist. The design of the arc-shaped cushion frame 72 should consider the physiological characteristics and comfort of the human sitting posture. A bushing 71 is provided on one side of the arc-shaped cushion frame 72, which is assembled and connected to the central rod 23. An electromagnet 73 is provided on the back of the arc-shaped cushion frame 72. The bushing 71 and the central rod 23 ensure that the magnetic protective claw 7 can be stably assembled on the central rod 23 and allows it to rotate or extend to adapt to different sitting postures. The fit between the bushing 71 and the central rod 23 should ensure stability and freedom of rotation. The electromagnet 73 generates magnetic force, allowing the magnetic protective claw 7 to adhere to the arc-shaped magnetic plate 62 behind it, providing stable support and protection for the user. The electromagnet 73 is designed to ensure its magnetic strength and stability, while also being easy to open and close via a control circuit. The magnetic protective claws 7 provide stable support and protection to the user through magnetic attraction or repulsion.

[0029] A rotating shaft 81 passes through the first mounting hole 14 and the second mounting hole 26. A rotary motor 8 is installed at the bottom of the rotating shaft 81. The rotating shaft 81 and the rotary motor 8 provide rotational power, enabling the traction magnetic module 6 to rotate around the rotating shaft 81. The design of the rotating shaft 81 should ensure its rotational stability and load-bearing capacity, while the rotary motor 8 should ensure its power and efficiency. The rotary motor 8 is located at the bottom of the upper base plate. The traction magnetic module 6 is fitted onto the rotating shaft 81. The traction magnetic module 6 includes an arc-shaped magnetic plate 62 and a sleeve 61. The sleeve 61 is connected and fixed to the rotating shaft 81. The arc-shaped magnetic plate 62 is provided on the sleeve 61 and is close to the magnetic protective claw 7. The traction magnetic module 6 generates a magnetic field through the arc-shaped magnetic plate 62, which interacts with the magnetic protective claw 7, allowing it to protect the patient while also generating a certain force to make the patient's training more effective. Sleeve 61 ensures that the traction magnetic module 6 can be stably mounted on the rotating shaft 81 and allows it to rotate.

[0030] The arc-shaped magnetic plate 62 can be a permanent magnet or an electromagnet. The surface of the pedal 32 is provided with anti-slip particles to prevent the shoes from slipping.

[0031] Example 2: Please refer to Figure 14. The threads inside the threaded sleeve 47 have different pitches. Because the threads inside the threaded sleeve 47 have different pitches, adjustments can be made based on the actual situation. If the patient's swaying force or the range of motion when standing is small, the sleeve can be rotated towards the end with the smaller pitch, resulting in a smaller reduction in the size of the third spring 42, which is more suitable for the patient.

[0032] Example 3: Referring to Figure 15, the pitch between the threads inside the threaded sleeve 47 is adjustable. In this example, the threaded sleeve 47 has an internal spring 9 and consists of an inner sleeve and an outer sleeve. The inner sleeve can rotate into the outer sleeve. The two ends of the internal spring 9 are fixedly mounted on the inner sleeve and the outer sleeve, respectively. When the inner sleeve rotates inward, the internal spring 9 is shortened; when the inner sleeve rotates outward, the internal spring 9 is lengthened, thereby changing the length of the internal spring 9. During assembly, the internal spring 9 and the third spring 42 engage with each other, thus allowing the length of the third spring 42 to be changed simultaneously.

[0033] Working Principle: During the analysis and protection of the patient's standing process, the patient is first seated on the cushion 2. The positioning arc surface 22 on the cushion 2 allows the patient's buttocks to automatically slide to the center position, ensuring correct positioning and facilitating subsequent testing. Then, the patient's feet are placed in the footrest 3 and positioned in the center. Finally, the clamping plate 133 is pulled up, causing the clip 135 to disengage from the toothed protrusion of the slide rod 45. The standing support frame 4 is then pushed towards the patient's chest. The clamp motor 53 is activated, causing the gripper 52 to clamp the patient's chest. At this point, the patient can undergo standing status detection and training. When the patient stands, their left and right feet exert a downward force on the pedal 32. This force is transmitted to the pressure sensor 311 via the second spring 322. First, for a single foot, each pressure sensor 311 in the outer frame 31 generates a pressure value, detecting the force on the foot in four directions and thus the force difference of the single foot. Second, for both feet, the pressure sensors 311 in the two footrests 3 summarize the pressure values, obtaining two pressure values ​​for the left and right feet. Analyzing these two pressure values ​​reveals the force difference and directional deviation between the left and right feet. During standing, the patient's chest moves forward, causing the standing clamp 5 in front of the chest to move forward. If the patient's upper body sways from side to side during standing, it further causes the left and right swing arms 51 to swing left and right. When the left and right swing arms 51 swing left and right, they generate a force on the two third springs 42 on the sides, which in turn transmit this force to the pressure sensor 43 at the end, thus detecting the left and right swaying of the body during standing. This detection is linear, monitoring the left and right swaying of the body in real time throughout the entire standing process, ultimately generating a graph showing the relationship between time and the force of the left and right swaying, allowing for better analysis and targeted training.

[0034] When the patient only needs to perform sitting correction or lumbar training, they only need to sit in the middle of the base 21. If the patient is not in the exact center of the base 21 when sitting down, the positioning arc surface 22 on the base 21 will automatically slide the patient's buttocks towards the center, positioning them in the exact center of the base 21. After the patient is in the exact center of the base 21, the sitting posture is adjusted. If the patient is tilted after sitting down, the force exerted by their upper body on the base 21 will not be in the vertical direction, further compressing the first spring 25 under the base 21. The compressed first spring 25 will exert pressure on the pressure sensor 12, and the magnitude of the pressure is recorded. By analyzing the four values ​​recorded by the four pressure sensors 12 on the upper base 21, the shift of the patient's upper body center of gravity can be determined, thereby adjusting the sitting posture. Secondly, when performing lumbar twisting or swaying training, protection can be provided. First, the electromagnet 73 is turned on. When the device is turned on, the electromagnet 73 and the curved magnetic plate 62 behind it will attract each other. After they attract each other, the rotary motor 8 will be turned on, and the rotating shaft 81 will rotate, causing the curved magnetic plate 62 to move closer to the patient's waist. When the magnetic protective claws 7 on both sides are in full contact with the patient, the current in the electromagnet 73 will reverse, and a repulsive force will be generated between the electromagnet 73 and the curved magnetic plate 62. At this time, the rotary motor 8 will stop rotating, the rotating shaft 81 will be fixed, and a magnetic space will be formed between the magnetic protective claws 7 and the curved magnetic plate 62. This allows the patient to be protected by the magnetic protective claws 7 while having a certain amount of space for training when performing left and right twisting or swaying exercises of the waist. Furthermore, when the patient performs left-right swaying exercises of the waist, the first spring 25 located on the left and right sides and the pressure sensor 12 corresponding to the first spring 25 will be subjected to different forces. When the patient shifts to one side, the pressure sensor 12 on that side will be subjected to greater pressure. At this time, the pressure sensor 12 will also send a signal to the electromagnet 73 on the corresponding side, increasing the current in the electromagnet 73 on that side, thereby strengthening the magnetic force on that side, thus providing greater support for the patient who is tilting to that side and better protecting the patient.

[0035] During the standing process, most patients are undergoing rehabilitation training, which may lead to insufficient lower limb strength or a tendency to tilt after standing, posing a safety hazard. The standing clamp 5, located on the chest, uses a clamp motor 53 to keep the gripper 52 firmly clamping the patient's chest. The gripper 52 is mounted on the upper crossbar 46 through the third mounting hole 511. The gripper 52 only slides left and right, not rotating, thus providing protection if the patient loses balance. Furthermore, the elastic coefficient of the third spring 42 can be adjusted via the threaded sleeve 47. For patients who are overweight or sway excessively while standing, a greater elastic force is needed for better protection. The length of the third spring 42 can be adjusted by rotating the threaded sleeve 47, thereby changing the elastic force and providing better protection for overweight patients or those with large swaying.
