Description

Technical Field

[0001] This disclosure pertains to the field of medical assistive devices, specifically relating to a comprehensive monitoring device for the elderly. Background Technology

[0002] As we age, the cartilage in our hip joints wears down and degenerates, resulting in an uneven joint surface. During movement, bone rubs against bone, causing inflammation and pain. When walking, each step requires a single leg to bear the full weight, subjecting the hip joint to enormous pressure and shearing forces. This is especially true when the joint surface is uneven, causing significant pain. When using a wheelchair, the weight is supported by the seat cushion, and the wheelchair's movement trajectory is relatively smooth. The range of motion of the joint is controlled and there is no impact, reducing friction and impact on the joint surface, thus alleviating pain. Therefore, wheelchairs are an important tool for rehabilitation. However, long-term use of wheelchairs for transfers during rehabilitation can easily lead to further decline in walking ability, muscle atrophy, or weakened balance.

[0003] When using a wheelchair, patients may involuntarily lean forward or fall off the wheelchair during sudden braking. In such cases, the user is restrained by the protective structure and cannot break free, and may be pressed down by the wheelchair for a long time, resulting in secondary injury.

[0004] For example, an osteoporosis fall prevention device with publication number CN113017617A is provided. This device is equipped with a ring-shaped trunk protection device and is installed on the upper torso of the human body. Several protective plates are fixed to the torso by a manually controllable and movable buffer device. When the body falls to the ground, the surrounding buffer device provides cushioning, which can protect the patient from multiple directions and prevent the patient from being injured.

[0005] However, although the device can protect the user at the moment of fall, the airbag wraps around the elderly more tightly after it deploys, making it difficult for them to break free from the airbag's restraint and to get up without assistance. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this disclosure is to provide a comprehensive monitoring device for the elderly, which solves the problem that in the prior art, wearable protective devices restrict the user's movement after a fall, making it difficult for the user to get up without external assistance.

[0007] The objective of this disclosure can be achieved through the following technical solutions: A comprehensive monitoring device for the elderly includes: a front support, a rear support, a seat cushion, and a support plate; A support plate is slidably arranged between the front support and the rear support. The front support, the rear support, and the support plate together form a wearable structure that surrounds the waist of the human body, and a seat cushion is fixed in the middle between the front support and the rear support. A vertically installed column is fixed to the outside of the support plate; Support legs are rotatably connected to the bottom of the front bracket and the rear bracket respectively; The side wall of the support plate is fixed with a limiting component to limit the sliding displacement of the support plate relative to the rear bracket. The front and rear brackets are provided with hydraulic grooves at one end near the support plate; The support leg has a hydraulic chamber inside; The support leg includes a support rod that is slidably connected to the hydraulic chamber; The hydraulic chute and the corresponding hydraulic chamber are connected by a connecting pipe, and the hydraulic chute, the hydraulic chamber and the connecting pipe are filled with damping fluid, forming a hydraulic damping assembly.

[0008] In some disclosures, the support leg further includes a support shell and a support spring, the outer sides of the front bracket and the rear bracket are rotatably connected to the support shell, and the inner side of the support shell is slidably engaged with the support rod, with the hydraulic chamber located inside the support shell.

[0009] In some disclosures, a plurality of hinged links are rotatably provided between the sidewall of the front support and the support leg rotatably connected to the front support, and the two ends of the links are rotatably connected to the support leg and the front support, respectively.

[0010] In some disclosures, the bottom of the support leg is fixed with a traveling wheel, and the traveling wheel near the front support is the drive wheel, while the traveling wheel near the rear support is the driven wheel. The inner side of the drive wheel integrates a motor.

[0011] In some disclosures, the limiting member includes a one-way groove and a limiting block adapted to the one-way groove. The one-way groove is provided on the outer side of the support plate, and a limiting block capable of sliding in one direction is provided on the inner side of the one-way groove.

[0012] In some disclosures, a plurality of triangular first elastic elements are fixed on the inner side of the slide groove, and a second elastic element adapted to the first elastic elements is fixed between the contact surface of the limiting block and the slide groove.

[0013] In some disclosures, the limiting component includes a magnetic limiting block and a metal support plate, with the limiting block being attracted to the support plate by the magnetic force of the magnet, while the side wall of the support plate is parallel to the end of the hydraulic chute.

[0014] In some disclosures, an elastic stop is provided on the inner side of the support shell, and a piston is fixed to the upper end of the support rod, and a connecting rod is fixed between the piston and the support rod, with the elastic stop located between the upper end faces of the piston and the support rod.

[0015] In some disclosures, the length of the column is greater than the height of the support leg when it is retracted to its shortest opening angle and at its maximum.

[0016] In some disclosures, the front and rear supports are covered with cushioning pads, and the cushioning pads are made of rubber or foam.

[0017] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows: A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them; A rotating connection is a connection between parts that allows the parts to rotate relative to each other. Threaded connections are a type of detachable fixed connection with advantages such as simple structure, reliable connection, and convenient assembly and disassembly. They are widely used in mechanical engineering and connection structure fields. A sliding connection is a connection between parts that allows the parts to slide against each other.

[0018] The beneficial effects of this disclosure are: 1. When the user's body is tilted and there is a risk of falling, the support leg in the tilting direction can automatically rotate outward and extend to contact the ground, forming a stable triangular support structure with the user's legs and the ground, providing upward support force and effectively reducing the risk of falling; at the same time, through the action of the hydraulic damping component, it can effectively absorb and buffer the impact energy during the extension of the support leg to the ground and the user's body falling, reducing the risk of injury to the user.

[0019] 2. By using the supporting legs to bear weight and drive the sliding of the support plate, the distance between the front and rear supports is effectively increased, expanding the user's range of motion and reducing local pressure on the lower back, thus improving user comfort. Simultaneously, the sliding displacement of the support plate alters the lever arm relationship of the front and rear supports and the column when the column is in contact with the ground, allowing the device to operate with a greater effort arm than resistance arm, forming a force-saving lever structure. When the user falls and sits down, shifting their center of gravity forward allows them to obtain effective support using this force-saving lever, reducing the effort required to get up and making the process easier and safer.

[0020] 3. By combining the wearable structure that wraps around the waist with the integrated hydraulic damping linkage system and the rotation and unfolding design of the support legs, the device effectively integrates the functions of anti-fall support, impact buffering, space adaptive adjustment and assisting in getting up. While ensuring complete functionality, it significantly improves the compactness and operational reliability of the overall structure of the device. Attached Figure Description

[0024] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0025] Please refer to Figures 1 to 7A comprehensive monitoring device for the elderly includes: a front support 1, a rear support 2, a seat cushion 10, and a support plate 3; A support plate 3 is slidably arranged between the front support 1 and the rear support 2. The front support 1, the rear support 2 and the support plate 3 together form a wearable structure that surrounds the waist of the human body, and a seat cushion 10 is fixed in the middle between the front support 1 and the rear support 2. A vertically arranged column 4 is fixed to the outside of the support plate 3; support legs 5 are rotatably connected to the bottom of the front bracket 1 and the rear bracket 2 respectively; a limit piece 6 is fixed to the side wall of the support plate 3 to limit the sliding displacement of the support plate 3 relative to the rear bracket 2. Hydraulic grooves 7 are provided at one end of the front bracket 1 and the rear bracket 2 near the support plate 3; The support leg 5 has a hydraulic chamber 51 inside; the support leg 5 includes a support rod 52 that is slidably connected to the hydraulic chamber 51. The hydraulic chute 7 and the corresponding hydraulic chamber 51 are connected by a connecting pipe 8, and the hydraulic chute 7, the hydraulic chamber 51 and the connecting pipe 8 are filled with damping fluid, forming a hydraulic damping assembly.

[0026] In use, damping fluid is filled into the hydraulic chamber 51 and the hydraulic slide 7, and the front support 1 and the rear support 2 are connected by the support plate 3. Then, the user sits on the seat cushion 10. At this time, the front support 1 and the rear support 2 are located at the user's waist. When the user leans forward, the support leg 5 on the front support 1 rotates away from the human body with the contact point with the ground as the center. When the support leg 5 rotates to the vertical position, the user's own weight presses the support rod 52 into the hydraulic chamber 51. When the support rod 52 slowly moves into the hydraulic chamber 51 under the action of the user's weight, the overall height of the support leg 5 gradually decreases, so that the user's center of gravity moves down smoothly.

[0027] At the same time, it pushes the damping fluid from the hydraulic chamber 51 to the hydraulic slide 7, which can reduce the impact between the user's body and the front support 1 during this process, avoid secondary injuries caused by a sudden drop in the center of gravity, and provide a smooth transition for the user to change to a sitting posture after falling.

[0028] Taking a user leaning forward as an example, the user's center of gravity is located on the support leg 5 of the front support 1, applying downward pressure to the front support 1. This causes the support rod 52 on the support leg 5 of the front support 1 to move closer to the front support 1. The damping fluid in the hydraulic chamber 51 flows back to the hydraulic groove 7 through the connecting pipe 8, pushing the support plate 3 away from the front support 1. Simultaneously, a limiting member 6 is fixed to the outside of the support plate 3, preventing the other end of the support plate 3 from inserting into the rear support 2. This allows the support plate 3 to slide along the hydraulic groove 7, moving the rear support 2 away from the front support 1, thus increasing the distance between the front support 1 and the rear support 2. This increases the user's range of motion and reduces the pressure exerted by the rear support 2 on the user. Furthermore, during this process, while the elderly user's center of gravity leans forward, the support leg 5 on the rear support 2 does not contact the ground. This means that when the damping fluid pushes the support plate 3 to slide, the damping effect of the rear support 2 on the support plate 3 is smaller, making it easier to push. At the same time, the damping fluid and the support rod 52 work together to buffer the impact force between the user and the front bracket 1, reducing the risk of injury to the user.

[0029] Even when an elderly user falls to the ground, the bottom of the upright 4 contacts the ground, and a lever structure is formed between the front support 1, the rear support 2, and the upright 4. At this time, the support plate 3 slides relative to the front support 1, and the torque between the front support 1, the rear support 2, and the upright 4 changes. At this time, the elderly user can sit on the front support 1 and then shift their center of gravity forward. At this time, the power arm is greater than the resistance arm, and the power is greater than the resistance. This can provide support for the user when they stand up, making it easier for the user to use leverage and thus complete the standing action more easily.

[0030] Please refer to Figures 2 to 4 The support leg 5 also includes a support shell 53 and a support spring 54. The outer sides of the front bracket 1 and the rear bracket 2 are rotatably connected to the support shell 53, and the inner side of the support shell 53 and the support rod 52 are slidably engaged. The hydraulic chamber 51 is located inside the support shell 53. The damping fluid in the support spring 54 and hydraulic chamber 51 cushions the impact of the support leg 5 on the user when it comes into contact with the ground, reducing the impact force on the user caused by the front support 1 and the rear support 2.

[0031] Please refer to Figures 1 to 2 Multiple connecting rods 9 are rotatably connected between the side wall of the front bracket 1 and the support leg 5 which is rotatably connected to the front bracket 1, and the two ends of the connecting rods 9 are rotatably connected to the support leg 5 and the front bracket 1 respectively.

[0032] The front support 1, the connecting rod 9, and the support leg 5 form a triangular structure. The connecting rod 9 further improves the stability of the connection between the support leg 5 and the front support 1. At the same time, the total length that the connecting rod 9 can extend when it is in a horizontal state is fixed. By using connecting rods 9 of different lengths, the maximum rotation angle of the support leg 5 can be limited, avoiding the problem of insufficient support force due to insufficient or excessive rotation angle.

[0033] Please refer to Figure 1 The bottom of the support leg 5 is fixed with a traveling wheel, and the traveling wheel on the side closer to the front bracket 1 is the drive wheel, while the traveling wheel on the side closer to the rear bracket 2 is the driven wheel. The inner side of the drive wheel integrates a motor. After the user sits on the seat cushion 10, they can drive the drive wheels to rotate and turn by adjusting the controller. The technology of driving the wheelchair to move and turn by the motor is already quite advanced, so it will not be described in detail.

[0034] First Embodiment Please refer to Figure 1 and Figure 7 The limiting component 6 includes a one-way sliding groove 62 and an elastic limiting block 61 adapted to the one-way sliding groove 62. The one-way sliding groove 62 is provided on the outer side of the support plate 3, and the elastic limiting block 61 capable of sliding in one direction is provided on the inner side of the one-way sliding groove 62.

[0035] When fitting, insert the support plate 3 into the hydraulic slide groove 7 until the elastic limit block 61 abuts against the port of the hydraulic slide groove 7. When the user leans forward, the damping fluid in the front bracket 1 pushes the support plate 3 to move closer to the rear bracket 2. The elastic limit block 61 restricts the support plate 3 from sliding directly into the hydraulic slide groove 7 in the rear bracket 2, so that when the damping fluid in the front bracket 1 pushes the support plate 3 to slide, it can push the support plate 3 and the rear bracket 2 to move together closer to the rear bracket 2.

[0036] Please refer to Figure 5 and Figure 7 Multiple triangular first elastic elements 611 are fixed inside the one-way slide groove 62, and a second elastic element 621 adapted to the first elastic element 611 is fixed between the contact surface of the elastic limiting block 61 and the one-way slide groove 62.

[0037] In use, the right-angled side of the triangle in the first elastic element 611 is perpendicular to the sidewall of the one-way slide groove 62 and is closer to the column 4. The right-angled side of the second elastic element 621 is parallel to the right-angled surface of the first elastic element 611. This allows the elastic limiting block 61 to move along the one-way slide groove 62 towards the column 4, causing elastic friction and elastic deformation between the inclined surfaces of the first elastic element 611 and the second elastic element 621. This allows the second elastic element 621 to pass through the first elastic element 611, thereby causing the elastic limiting block 61 to slide along the one-way slide groove 62 towards the column 4, achieving one-way sliding. When the damping fluid in the current bracket 1 pushes the support plate 3 towards the rear bracket 2, the hydraulic slide groove of the rear bracket 2... The port of 7 abuts against its corresponding elastic limiting block 61. At this time, the right-angled surface of the first elastic element 611 abuts against the direct surface of the second elastic element 621, thereby restricting the sliding of the elastic limiting block 61. In this way, the relative position of the elastic limiting block 61 on the support plate 3 can be adjusted. Through the cooperation of the first elastic element 611 and the second elastic element 621 on the one-way slide groove 62, the position of the elastic limiting block 61 and the support plate 3 can be freely adjusted, which is beneficial to adjusting the distance between the front and rear supports. The distance between the front and rear supports can be flexibly adjusted according to the user's body shape or usage scenario (such as storage / wearing), so that the distance between the front and rear support frames is smaller when storing or using, occupying less space and making it more convenient to operate.

[0038] Second Embodiment Please refer to Figure 2 The limiting component 6 includes a magnetic limiting block 11 and a metal support plate 3. The magnetic limiting block 11 is attracted to the support plate 3 by the magnetic force of the magnet, and the side wall of the support plate 3 is parallel to the end of the hydraulic slide 7.

[0039] In use, the magnetic limiting block 11 is attached to the outside of the support plate 3 at a suitable position. The magnetic limiting block 11 is attached to the support plate 3 by magnetic force. At this time, the side of the magnetic limiting block 11 near the end of the hydraulic slide 7 is parallel to the port plane of the hydraulic slide 7, thereby increasing the contact surface between the magnetic limiting block 11 and the end of the hydraulic slide 7.

[0040] Please refer to Figure 4 An elastic stop 512 is provided on the inner side of the support shell 53, and a piston 511 is fixed at the upper end of the support rod 52. A connecting rod 521 is fixed between the piston 511 and the support rod 52. The elastic stop 512 is located between the upper end face of the piston 511 and the support rod 52.

[0041] When the user sits on the seat cushion 10, the user's own weight causes the support rod 52 to retract inward along the support shell 53, and then stops due to the resistance of the elastic stop 512. At this time, since the support leg 5 is tilted relative to the front support 1, the weight of the user and the seat cushion 10 is applied to the support leg 5 in a non-vertical state. Therefore, the component force of the support rod 52 on the elastic stop 512 is less than the force that causes the elastic stop 512 to undergo elastic deformation. When the device moves, the relative position between the support rod 52 and the support shell 53 will remain on one side of the elastic stop 512. When tilting forward or backward, causing the vehicle to overturn, the device rotates around the bottom of the support leg 5, which is rotatably connected to the front support 1, as the center. When the support leg 5 rotates to the point where the support rod 52 and the elastic stop 512 rotate... When the support rod 52 moves to the same vertical line, the pressure of the support shell 53 on the support rod 52 increases. The support rod 52 squeezes the elastic stop 512, causing the elastic stop 512 to deform. That is, the middle part of the elastic stop 512 contracts and deforms elastically towards the side closer to the inner wall of the hydraulic chamber 51. At this time, the upper end face of the support rod 52 passes through the elastic stop 512 and pushes the connecting rod 521 and the piston 511 to move upward along the hydraulic chamber 51, and pushes the damping fluid into the corresponding hydraulic groove 7. Since the piston 511 is located at the end of the elastic stop 512 away from the support rod 52, the piston 511 will not have a rigid collision with the hydraulic rod during this process, thus reducing the wear of the piston 511. The fact that the damping fluid is always stored on the side of the piston 511 away from the support rod 52 can reduce the leakage of the damping fluid.

[0042] Please refer to Figure 8 The length of the column 4 is greater than the height of the support leg 5 when it is retracted to its shortest and most open angle.

[0043] If the device tilts forward and falls, and the user is safe and uninjured, they can reverse the flipped support by using their arms, bringing the multiple support legs 5 into contact with the ground. At this point, the height of the support legs 5 on the front support 1 decreases, causing the bottom of the column 4 to contact the ground. The height of the support legs 5 on the front support 1 is lower than the height of the column 4 and also lower than the height of the rear support 2. This creates a ramp between the front support 1, the rear support 2, and the support plate 3. If the user's leg muscle atrophy is not severe, after resting, the user can gradually move along the front support 1 towards the higher rear support 2, using the ramp for support to stand up. If the user's leg strength is insufficient to stand up, they can rotate the support legs 5 along the ramp. The hinge point connecting the frame 1 and the rear support 2 rotates inward, causing the supports on both sides of the column 4 to form a lever structure. When falling, the support plate 3 and the rear support 2 move away from the front support 1, making the distance between the end of the front support 1 and the column 4 smaller than the distance between the end of the rear support 2 and the column 4. At this time, the user sits on the rear support 2 and presses the front support 1 downward with their arms while leaning forward. Under the same downward pressure, the length of the effort arm in the lever is greater than the length of the resistance arm, thus forming a force-saving structure. At this time, the height of the rear support 2 from the ground is 30-50 cm, which makes it convenient for the user to apply force, thus making it easier for users with insufficient leg strength to stand up without assistance.

[0044] The front bracket 1 and the rear bracket 2 are covered with a cushioning pad 12, which is made of rubber or foam.

[0045] Using soft rubber or foam materials can reduce user discomfort when in contact with the front bracket 1 and the rear bracket 2, which helps to further improve the safety of the device.

[0046] The following description, in conjunction with the accompanying drawings and embodiments, provides a further explanation of the comprehensive condition monitoring device for the elderly provided by the present invention.

[0047] When the user wears the device, the two ends of the support plate 3 are inserted into the hydraulic grooves 7 of the front support 1 and the rear support 2, respectively. The position of the support plate 3 is adjusted by the elastic limiting block 61 of the limiting member 6 cooperating with the one-way groove 62, so that the front support 1, the rear support 2 and the support plate 3 form a structure that surrounds the waist. The seat cushion 10 is fixed in the middle of the front / rear support. When the user sits on the seat cushion 10, the support leg 5 contacts the ground. At this time, the support rod 52 retracts into the hydraulic chamber 51 under the action of gravity. The sliding stops when the support rod 52 moves to abut against the elastic stop 512. During the retraction process, the support rod 52 compresses the support spring 54 inward. Then, the drive wheel is forcibly turned by the operator.

[0048] If the user falls forward due to sudden braking, the support leg 5 of the front support 1 rotates away from the body from the point of contact with the ground to a vertical position. The support rod 52 is continuously pressed into the hydraulic chamber 51, pushing the damping fluid into the hydraulic slide 7 through the connecting pipe 8. During this process, the support spring 54 is further compressed. At the same time, when the support rod 52 pushes the damping fluid, it can buffer the impact force between the user and the front support 1, so that the height of the support leg 5 gradually decreases to achieve buffering. At the same time, the damping fluid in the hydraulic slide 7 of the front support 1 pushes the support plate 3 to slide away from the front support 1, driving the rear support 2 to move synchronously. At this time, the limiting member 6 prevents the support plate 3 from falling out of the hydraulic slide 7, while the inclined surfaces of the first elastic member 611 and the second elastic member 621 in the one-way slide 62 allow the elastic limiting block 61 to slide in one direction to adjust the distance, increase the distance between the front and rear supports and reduce the pressure on the waist. When a user falls to the ground, the upright 4 forms a fulcrum upon contact with the ground. Due to the displacement of the support plate 3, the distance between the end of the front support 1 and the upright 4 is less than the distance between the end of the rear support 2, creating a lever with a power arm greater than the resistance arm. When the user is seated on the rear support 2, they can use the leverage to stand up by pressing down on the front support 1 with their arms. If a rollover causes the support leg 5 to rotate to a vertical position, the support rod 52 compresses the elastic stop 512, causing it to deform. The piston 511 moves upward, pushing the damping fluid to flow and preventing rigid collisions. The cushioning pad 12 covers the surface of the support to reduce discomfort, and the walking wheel motor supports a mobile mode.
