Description

Technical Field

[0001] This utility model relates to the technical field of exercise equipment for geriatric patients, and in particular to a lower limb exercise and care device for geriatric patients. Background Technology

[0002] Geriatric diseases, also known as age-related diseases, refer to aging-related diseases that occur in the elderly and have their own characteristics. The elderly not only suffer from more diseases than young people, but also have their own characteristics. This is mainly because as people enter old age, the structure of human tissues further ages, the functions of various organs gradually become impaired, the body's resistance gradually weakens, the ability to move decreases, and the coordination function is lost.

[0003] Currently, most elderly patients lack the ability to exercise independently, and those who have been bedridden for a long time have lost the ability to walk independently. Existing lower limb exercise and care equipment for elderly patients who cannot get out of bed is basically all one-way exercise, which is relatively monotonous and therefore easily leads to insufficient exercise.

[0055] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0056] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0057] like Figures 1 to 5 As shown in the embodiment of this application, a lower limb exercise and nursing device for geriatric patients is proposed, comprising: a support body 100; a leg exercise component 200 disposed on the support body 100; the leg exercise component 200 comprising: a bearing body 210 disposed on the support body 100; two movable plates 220 mounted opposite to each other on the bearing body 210; and a foot fixing seat 230 for fixing the foot and slidably mounted on the movable plates 220; wherein the moving direction of the foot fixing seat 230 is perpendicular to the moving direction of the movable plates 220.

[0058] The lower limb exercise and nursing device for geriatric patients provided in this application embodiment includes a support body 210, two movable plates 220, and a foot fixing seat 230. The support body 210 is disposed on the support body 100 and undertakes the function of supporting and integrating other components of the leg exercise component 200. It not only provides a platform for the installation of each component, but also ensures that the entire leg exercise component 200 can be stably connected to the support body 100, thereby ensuring the stability of the entire device structure during the patient's exercise.

[0059] Two movable plates 220 are mounted opposite each other on the support body 210. The movement of the movable plates 220 can drive the foot fixing seat 230 to move back and forth within the horizontal range defined by the support body 210. The movement mode can simulate some of the movements of the human lower limbs during walking, and strengthen the flexion and extension of the leg muscles in the horizontal direction.

[0060] The main function of the foot fixation seat 230 is to fix the patient's foot and ensure its stability during exercise. It is slidably mounted on the moving plate 220, and its direction of movement is perpendicular to that of the moving plate 220. The foot fixation seat 230 can also produce vertical displacement based on the movement of the moving plate 220. For example, when the moving plate 220 moves horizontally, the foot fixation seat 230 can slide vertically at the same time. This greatly enriches the movement trajectory of the patient's lower limbs and provides more multi-dimensional exercise for the lower limb muscles. It is no longer limited to the traditional single-direction exercise method. The patient can perform horizontal and vertical movement training at the same time, which helps to comprehensively improve the strength, flexibility and coordination of the leg muscles.

[0061] like Figures 1 to 5 As shown, in some examples, the leg exercise component 200 further includes a moving mechanism 240 disposed within the supporting body 210, with two moving plates 220 disposed opposite to each other on the moving mechanism 240, for moving the two moving plates 220 toward each other or away from each other.

[0062] In this technical solution, the leg exercise component 200 also includes a moving mechanism 240, which is located inside the supporting body 210. The moving mechanism 240 drives two opposing moving plates 220 to move, allowing the two moving plates 220 to move closer to or further away from each other. By driving the two moving plates 220 closer or further away through the moving mechanism 240, multiple exercise modes are provided for the legs of elderly patients. When the two moving plates 220 move closer, the distance between the foot fixing seats 230 decreases, simulating the inward retraction of the legs, which helps to exercise the inner leg muscles and enhance their contractile ability. Conversely, when the two moving plates 220 move further away, it is equivalent to the legs performing an abduction movement, focusing on exercising the outer leg muscles, improving their strength and endurance, and enriching the dimensions of lower limb exercise. Compared to traditional single-mode exercise, it can more comprehensively stimulate different parts of the leg muscles, improve the effect of muscle training, and meet the diverse rehabilitation training needs of elderly patients.

[0063] The moving mechanism 240 works in conjunction with the supporting body 210, the moving plate 220, and the foot fixation seat 230. The supporting body 210 provides installation space and structural support for the moving mechanism 240, ensuring its stable operation. The moving mechanism 240 controls the movement of the moving plate 220, creating conditions for the movement of the foot fixation seat 230. After the foot fixation seat 230 fixes the patient's foot, it realizes a variety of lower limb exercise movements as the moving plate 220 moves and slides in a direction perpendicular to the moving plate 220. This design of close coordination between the components fully reflects the systematic and scientific nature of the equipment in realizing comprehensive lower limb exercise for elderly patients, which helps to improve the practicality and effectiveness of the equipment and better assist the rehabilitation training process of elderly patients.

[0064] like Figure 3 As shown, in some examples, the moving mechanism 240 includes: a linkage gear 241, which is rotatably mounted in the bearing body 210; a rack 242, which is slidably mounted in the bearing body 210 and fixedly connected to the moving plate 220; and two racks 242 are respectively disposed on both sides of the linkage gear 241 and mesh with the linkage gear 241.

[0065] In this technical solution, the moving mechanism 240 includes a linkage gear 241 and a rack 242. The linkage gear 241 is rotatably mounted inside the bearing body 210. The bearing body 210 plays the role of supporting and positioning the linkage gear 241 in this process, enabling it to maintain a stable rotational state and laying the foundation for subsequent power transmission and the realization of the moving function. The rack 242 is slidably mounted inside the bearing body 210 and is fixedly connected to the moving plate 220. Under the guidance and constraint of the bearing body 210, the rack 242 can slide linearly along a specific path. Since it is fixedly connected to the moving plate 220, when the rack 242 slides, it will drive the moving plate 220 connected to it to move together.

[0066] Two racks 242 are respectively disposed on both sides of the linkage gear 241 and mesh with it. When the linkage gear 241 rotates, based on the meshing transmission principle of gears and racks, the racks 242 on both sides of the linkage gear 241 will be subjected to forces in opposite directions. Since the two racks 242 are fixedly connected to the two moving plates 220 respectively, these opposing forces will cause the two moving plates 220 to move closer to or further away from each other. For example, when the linkage gear 241 rotates clockwise, one rack 242 will slide to the left under meshing action, and the moving plate 220 connected to it will also move to the left; at the same time, the other rack 242 will slide to the right under the drive of the linkage gear 241, driving the corresponding moving plate 220 to move to the right, thus making the two moving plates 220 move away from each other. Conversely, when the linkage gear 241 rotates counterclockwise, the two moving plates 220 will move closer to each other.

[0067] The meshing transmission of the linkage gear 241 and rack 242 can precisely control the synchronous movement of the two moving plates 220, so that the two moving plates 220 maintain a stable distance change and movement rhythm during relative movement. This ensures that the legs of elderly patients can receive balanced and symmetrical exercise when performing lower limb exercises. Secondly, the gear and rack transmission structure has high transmission efficiency and reliability, which can effectively transmit power to the moving plates 220. It is not prone to failure during long-term use, ensuring that the equipment can operate stably and effectively during long-term use, providing continuous and stable lower limb exercise support for elderly patients and better meeting their rehabilitation exercise needs.

[0068] like Figure 3 As shown, in some examples, the aforementioned moving mechanism 240 includes: a drive motor 243 disposed within the aforementioned supporting body 210; a crank 244, one end of which is fixedly connected to the output end of the aforementioned drive motor 243; an auxiliary frame 245 fixedly mounted on one of the aforementioned racks 242, wherein the aforementioned auxiliary frame 245 and the aforementioned rack 242 are perpendicular to each other, and the other end of the aforementioned crank 244 is slidably mounted within the aforementioned auxiliary frame 225.

[0069] In this technical solution, the moving mechanism 240 also includes a drive motor 243, a crank 244, and an auxiliary frame 245. The drive motor 243 is located inside the supporting body 210 and serves as the power source for the entire moving mechanism 240, providing the necessary energy for the operation of the equipment. After the drive motor 243 is turned on, it can continuously output stable rotational power. One end of the crank 244 is fixedly connected to the output end of the drive motor 243. The crank 244 can directly obtain rotational power from the drive motor 243 and perform circular motion as the drive motor 243 rotates. The rotational force of the drive motor 243 is transmitted to the circular motion of the crank 244. The auxiliary frame 245 is fixedly installed on one of the racks 242 and is perpendicular to the racks 242. The auxiliary frame 245 can move together with the sliding of the racks 242. At the same time, the other end of the crank 244 is slidably installed inside the auxiliary frame 245. When the drive motor 243 drives the crank 244 to make circular motion, the other end of the crank 244 slides in the auxiliary frame 245. Since the auxiliary frame 245 is connected to the rack 242, the sliding motion of the crank 244 in the auxiliary frame 245 is converted into the linear reciprocating motion of the rack 242. Then, through the fixed connection between the rack 242 and the moving plate 220, the moving plate 220 is pushed to move towards each other or away from each other, so as to realize the specific movement mode required for the lower limb exercise of elderly patients.

[0070] like Figure 1 and Figure 4 As shown, in some examples, the lower limb exercise and care device for geriatric patients further includes: a first locking component 300, disposed between the movable plate 210 and the foot fixing seat 230, for fixing the movable plate 210 and the foot fixing seat 230 relative to each other. The first locking component 300 includes: a first telescopic rod 310 disposed within the movable plate 220; and a first locking groove 320 disposed within the foot fixing seat 230, wherein when the first telescopic rod 310 extends into the first locking groove 320, the foot fixing seat 230 and the movable plate 220 are fixed relative to each other.

[0071] In this technical solution, the first locking component 300 is disposed between the movable plate 220 and the foot fixing seat 23, so that the two components can be relatively fixed, ensuring that the foot is stably fixed on the movable plate 220 during exercise and follows the movement of the movable plate 220 to perform corresponding exercise movements, avoiding the impact of foot slippage or shaking on the exercise effect, or even causing accidental injury to the patient.

[0072] The first telescopic rod 310 is disposed within the movable plate 220 and has the characteristic of being telescopic. The first telescopic rod 310 can change its length according to actual needs. The first locking groove 320 is disposed within the foot fixing seat 230 and cooperates with the first telescopic rod 310. When the first telescopic rod 310 extends and enters the first locking groove 320, it is like a key being inserted into a lock hole, and the two form a mechanical locking state. At this time, the foot fixing seat 230 and the movable plate 220 are relatively fixed together and can move in coordination.

[0073] like Figure 2 and Figure 5 As shown, in some examples, the aforementioned load-bearing body 210 is rotatably mounted on the aforementioned support body 100. A second locking component 400 is provided between the load-bearing body 210 and the aforementioned support body 100 to fix the load-bearing body 210 and the aforementioned support body 100 relative to each other. The aforementioned second locking component 400 includes: a second telescopic rod 410 disposed on the aforementioned load-bearing body 210; and a second locking groove 420 disposed circumferentially and equidistantly on the aforementioned support body 100. When the aforementioned second telescopic rod 410 extends into the aforementioned second locking groove 420, the aforementioned load-bearing body 210 and the aforementioned support body 100 are relatively fixed.

[0074] In this technical solution, the bearing body 210 is rotatably mounted on the support body 100. The bearing body 210 can rotate relative to the support body 100. The function of the second locking component 400 is to fix the bearing body 210 and the support body 100 relatively when needed. The angle of the bearing body 210 can be adjusted according to the different exercise needs or body positions of elderly patients. After being adjusted to a suitable position, the second locking component 400 is used to lock it, ensuring that the bearing body 210 remains stable during exercise, thereby ensuring the safety and effectiveness of exercise.

[0075] The second telescopic rod 410 is mounted on the support body 210 and has a telescopic function. Under the control of the support body 210, its length can be changed according to actual needs. When it is necessary to adjust the angle of the support body 210, the second telescopic rod 410 can retract, allowing the support body 210 to rotate freely. After adjusting to the ideal angle position, the second telescopic rod 410 will extend to prepare for subsequent cooperation with the second locking groove 420 to achieve the locking function.

[0076] When the second telescopic rod 410 extends into the second locking groove 420, the supporting body 210 and the supporting body 100 are relatively fixed. Since the extension and retraction of the second telescopic rod 410 is controlled by the supporting body 210, and the second locking groove 420 is fixed to the supporting body 100, once the two are precisely engaged, it is like a mortise and tenon joint in a mechanical structure, effectively preventing the rotation of the supporting body 210 relative to the supporting body 100, thus ensuring the stability of the supporting body 210 at a specific angle. For example, when an elderly patient needs to perform lower limb exercises at a specific tilt angle, medical staff can first rotate the supporting body 210 to a suitable angle, and then extend the second telescopic rod 410 to enter the corresponding position of the second locking groove 420, fixing the supporting body 210 and ensuring the stability of the equipment structure throughout the exercise, providing a safe and reliable exercise environment for the patient.

[0077] like Figure 2 As shown, in some examples, the lower limb exercise and care device for geriatric patients further includes: a mounting assembly 500 disposed on the support body 100 for detachably mounting the support body 100 onto the bed. The mounting assembly 500 includes: at least two fixing frames 510, forming an installation space 501 with a lower opening between the fixing frames 510 and the support body 100; a compression block 520 disposed within the installation space 501; and an adjusting bolt 530 threaded through the fixing frames 510 and rotatably connected to the compression block 520.

[0078] In this technical solution, the mounting component 500 is set on the support body 100, which can be detachably installed on the bed. For elderly patients, if the device can be installed on their daily bed, it can avoid frequent patient transfers and reduce physical burden and discomfort. On the other hand, the detachable installation allows the device to be easily removed when not in use, without taking up too much space, and also makes it easy to clean, store or move the device to other beds.

[0079] There are at least two fixed frames 510, which together with the support body 100 form an installation space 501 with an opening at the bottom. As the basic support structure of the installation component 500, the fixed frames 510 not only provide a stable framework for the entire installation process, but the installation space 501 is also a key part for connecting with the bed. This space 501 with an opening at the bottom can accommodate part of the bed structure, usually the bed edge, etc., creating conditions for the subsequent fixing of the equipment to the bed.

[0080] The pressing block 520 is set within the installation space 501. The adjusting bolt 530 is threaded through the fixing frame 510 and rotatably connected to the pressing block 520. When the equipment needs to be installed on the bed, the position of the pressing block 520 within the installation space 501 can be adjusted by rotating the adjusting bolt 530. When the adjusting bolt 530 is rotated, it moves along the thread direction. The pressing block 520 is rotatably connected to the adjusting bolt 530, so that the rotation of the adjusting bolt 530 is converted into the linear movement of the pressing block 520. As the pressing block 520 moves, the width of the installation space 501 changes accordingly, thereby tightly clamping the edge of the bed and firmly fixing the support body 100 to the bed. When the equipment needs to be disassembled, the adjusting bolt 530 is rotated in the opposite direction, and the pressing block 520 moves back to its original position, releasing the clamping force on the bed, and the equipment can be easily removed from the bed.
