[0002] With the accelerated development of the global aging society, the health problems of the elderly have received increasing attention, especially the decline of lower limb strength has become an important factor affecting their quality of life. Insufficient lower limb strength not only leads to inconvenience in movement, but also may increase the risk of falling, which in turn leads to serious health problems. Therefore, accurate assessment of the lower limb strength of the elderly is of great significance for preventing falls, formulating rehabilitation plans, and improving the quality of life. At present, there are some lower limb strength testing equipment on the market, but most of these equipment are designed for healthy people and fail to fully consider the special needs of the elderly.

[0028] Embodiment 1: The invention provides lower limb strength testing equipment for the elderly.

[0029] In one embodiment of the present invention, the lower limb strength testing device 100 for the elderly includes a slide 1, a detection mechanism 2 and a rehabilitation training mechanism 3. The slide 1 is detachably mounted on a bed 200 through a clamping assembly. The detection mechanism 2 is arranged on the slide 1 and can move relative to the bed 200 through the slide 1. The detection mechanism 2 includes a fixed seat 4 and a movable seat 5. First pressure sensors 6 are respectively arranged on opposite sides of the fixed seat 4. The movable seat 5 is limitedly and movably mounted between the two first pressure sensors 6 and is used to install the rehabilitation training mechanism 3. The rehabilitation training mechanism 3 includes a support rod 7, a first drive assembly 8 and a second drive assembly 9. A pedal 10 is movably mounted on the support rod 7 and a second pressure sensor 11 is arranged below the pedal 10. The first drive assembly 8 is used to drive the support rod 7 to rotate relative to the movable seat 5, and the second drive assembly 9 is used to drive the support rod 7 to rotate relative to the first drive assembly 8.

[0030] Specifically, Figures 1 to 5As shown, in the lower limb strength testing equipment 100 for the elderly of the present invention, since the slide 1 is detachably mounted on the bed 200 through a clamping assembly, the clamping assembly can be a buckle or a clamping claw, etc., which not only facilitates the disassembly and assembly of the slide 1, but also enables the slide 1 to be installed on beds 200 of different specifications and sizes, thereby improving versatility and flexibility of use; at the same time, the slide 1 can drive the detection mechanism 2 to move in a manner such as a cylinder, a hydraulic cylinder, a screw transmission mechanism or an electric push rod, etc., so that the detection mechanism 2 can move on the slide 1 relative to the bed 200, and then can adapt to the specific lying position of the elderly on the bed 200. Not only does the elderly do not need to move their own position to adapt to the detection mechanism 2, but it is more convenient and comfortable to use, which improves the user experience, and can also meet the use needs of the elderly of different heights and sizes, thereby enhancing applicability. To sum up, during the use of the lower limb strength testing equipment 100 for the elderly of the present invention, for the elderly or users with mobility impairments, the user only needs to lie on the bed 200 to perform a lower limb strength test, and the slide 1 can enable the detection mechanism 2 to move and adapt to the user's specific lying position without the user having to adjust the position or posture by himself, thereby greatly improving the convenience of use, reducing the risk of accidental falls of the user during the test, reducing the probability of the user suffering secondary injuries due to the lower limb strength test, and ensuring safety of use.

[0031] Furthermore, since the detection mechanism 2 is arranged on the slide 1, the fixed seat 4 in the detection mechanism 2 can be installed on the slide 1 by means of threaded connection or the like, thereby facilitating the disassembly and assembly of the entire detection mechanism 2 and facilitating maintenance; at the same time, since the first pressure sensors 6 are respectively arranged on the opposite sides of the fixed seat 4, and the movable seat 5 in the detection mechanism 2 is installed between the two first pressure sensors 6 in a limited and movable manner, the installation method of the movable seat 5 and the fixed seat 4 in a limited and movable manner can be adopted as a slide groove clamping, that is, a slide groove is opened on the fixed seat 4, the movable seat 5 is clamped in the slide groove and can slide relative to the fixed seat 4 along the extension direction of the slide groove, and the two first pressure sensors 6 are respectively located on the opposite sides of the fixed seat 4, thereby enabling the movable seat 5 to abut or separate from the two first pressure sensors 6, and the structural design is simple and reasonable.

[0032] It can be understood that when it is necessary to test the user's lower limb strength, after the medical staff adjusts the detection mechanism 2 into place, the user's soles can step on the pedal 10 on the rehabilitation training mechanism 3, and the user's legs are naturally bent. Since the rehabilitation training mechanism 3 is installed on the movable seat 5, and the movable seat 5 can move relative to the fixed seat 4, the rehabilitation training mechanism 3 can also move relative to the fixed seat 4 under the action of the movable seat 5. The user straightens his legs at this time, so that the rehabilitation training mechanism 3 drives the movable seat 5 to move relative to the fixed seat 4. When the user straightens his legs or stretches his legs to the extreme position, the movable seat 5 can abut against the first pressure sensor 6 away from the user. The first pressure sensor 6 can test the user's muscle strength when stretching his legs. The first pressure sensor 6 transmits data to an external terminal device, which is convenient for medical staff to evaluate the user's lower limb strength level when stretching his legs. In addition, during actual use of the lower limb strength testing device 100 for the elderly of the present invention, when the sole of the user steps on the pedal 10, the sole of the user's foot can be firmly tied to the pedal 10 by installing a strap on the pedal 10 (the strap is a conventional and mature prior art, and its specific structure is not shown in the drawings of the specification), etc., thereby preventing the sole of the user's foot from being separated from the pedal 10 during the test and affecting the test. Similarly, when the user contracts his legs, the rehabilitation training mechanism 3 and the movable seat 5 move toward the user, that is, the movable seat 5 can abut against the first pressure sensor 6 close to the user, and the first pressure sensor 6 can be used to test the muscle strength of the user when contracting his legs, so that it is convenient for medical staff to evaluate the lower limb strength level of the user when contracting his legs. To sum up, the lower limb strength testing equipment 100 for the elderly of the present invention can drive the movable seat 5 to contact the two first pressure sensors 6 respectively through the user's leg extension and leg retraction movements, and thereby test the muscle strength of the user when extending and retracting the legs, thereby not only facilitating medical staff to evaluate the user's lower limb strength, but also realizing a comprehensive test of the lower limb strength, with a wide test range, and convenient and reliable use.

[0033] It is worth noting that the pedal 10 and the support rod 7 can be movably mounted in a pin-shaft connection, that is, the pedal 10 is provided with pins on both sides of the pedal 10, so that the pedal 10 can rotate relative to the support rod 7. Since the second pressure sensor 11 is provided below the pedal 10, when the user's sole steps on the pedal 10, the user's sole can step on the pedal 10 to rotate it relative to the support rod 7. At this time, the pedal 10 abuts against the second pressure sensor 11, so that the second pressure sensor 11 can test the muscle strength of the user's sole when the sole steps, thereby facilitating medical staff to evaluate the lower limb strength of the user's sole when stepping, further expanding the test range and having strong applicability.

[0034] It should be noted that, during actual use of the lower limb strength testing device 100 for the elderly of the present invention, when the sole of the user steps on the pedal 10, the first driving assembly 8 in the rehabilitation training mechanism 3 can drive the support rod 7 to rotate relative to the movable seat 5, thereby driving the user's lower limb to rotate relative to the upper limb with the hip joint as the rotation point; at the same time, since the second driving assembly 9 in the rehabilitation training mechanism 3 can drive the support rod 7 to rotate relative to the first driving assembly 8, the user's calf can be driven to rotate relative to the thigh with the knee joint as the rotation point, and the first driving assembly 8 and the second driving assembly 9 can drive the user's sole to rotate relative to the calf with the ankle joint when running synchronously, thereby effectively increasing the range of motion of the hip joint, knee joint and ankle joint, promoting the secretion of synovial fluid in the elderly, improving joint flexibility, relieving joint stiffness, and stimulating the contraction and relaxation of the lower limb muscles (such as quadriceps, hamstrings, calf muscles), helping to enhance and restore muscle strength, meet the use needs of the elderly for rehabilitation training, and expand the scope of use, enrich the use function, have good economy, and are worthy of promotion.

[0035] In one embodiment, the first driving assembly 8 includes a connecting rod 12 and a first driving member 13. The first driving member 13 is detachably mounted on the movable seat 5. One end of the connecting rod 12 is sleeved on the power output end of the first driving member 13. The other end of the connecting rod 12 is rotationally connected to the support rod 7. Specifically, Figure 3 and Figure 4 As shown, the first driving member 13 and the movable seat 5 can be detachably installed in a threaded connection, which is convenient for disassembly, assembly and replacement of the first driving member 13 and is convenient for maintenance. Further, the first driving member 13 can be a motor, and one end of the connecting rod 12 is sleeved on the power output end of the first driving member 13 by means of threaded connection, so that the first driving member 13 can drive the connecting rod 12 to rotate relative to the movable seat 5. Since the other end of the connecting rod 12 is connected to the support rod 7 in a limited rotation connection, the connection rod 12 and the support rod 7 can be connected in a limited rotation connection manner such as bolt connection, so that the support rod 7 can rotate synchronously with the connecting rod 12, and the structural design is simple and reasonable. It can be understood that when the user's sole steps on the pedal 10, the first driving member 13 runs and drives the support rod 7 and the connecting rod 12 to rotate, thereby being able to synchronously drive the user's lower limbs to rotate relative to the upper limbs with the hip joint as the rotation point, thereby increasing the range of motion of the hip joint, which is conducive to rehabilitation training for the lower limbs.

[0036] In one embodiment, the second driving assembly 9 includes a second driving member 14, the second driving member 14 is hinged on the connecting rod 12, and the power output end of the second driving member 14 is hinged to the support rod 7, so that the second driving member 14 drives the support rod 7 to rotate in a direction away from or close to the connecting rod 12. Specifically, Figure 3 and Figure 4 As shown, the second driving member 14 can be a cylinder, a hydraulic cylinder, a motor screw transmission mechanism or an electric push rod in the prior art, and since the second driving member 14 is hinged on the connecting rod 12, the power output end of the second driving member 14 is hinged to the support rod 7, so that not only the support rod 7 can be supported by the second driving member 14 to prevent the support rod 7 from rotating freely relative to the connecting rod 12, but the support rod 7 can also be driven to rotate by the second driving member 14, so that the user's calf can rotate relative to the thigh with the knee joint as the rotation point, thereby increasing the range of motion of the knee joint, which is beneficial to rehabilitation training of the lower limbs.

[0037] In one embodiment, a connecting seat 15 is detachably mounted on one end of the support rod 7 away from the connecting rod 12, the pedal 10 is rotatably mounted on the connecting seat 15, and an elastic member 16 is arranged between the pedal 10 and the connecting seat 15, a limiting wall 17 is formed on the top surface of the pedal 10 along its circumference, a protrusion 18 is arranged on the bottom surface of the pedal 10, and a second pressure sensor 11 is arranged at a position corresponding to the protrusion 18 on the connecting seat 15.

[0038] Specifically, Figures 3 to 5 As shown, the user's sole can be positioned by the limiting wall 17 formed on the pedal 10, so as to prevent the sole of the user's foot from being separated from the pedal 10 when the user's leg is extended or contracted, and the pedal 10 is reliable to use. Furthermore, since an elastic member 16 is provided between the pedal 10 and the connecting seat 15, the elastic member 16 can be a spring in the prior art, which has the characteristics of compact structure, easy material acquisition and large elastic recovery force. When the user steps on the pedal 10, the pedal 10 can drive the user's sole to return to the initial position under the action of the elastic member 16. In this process, the user's sole rotates relative to the calf at the ankle joint, thereby increasing the range of motion of the ankle joint, so that the user can repeatedly step on the pedal 10 to achieve rehabilitation training for the sole of the foot. It can be understood that when the user steps on the pedal 10, the protrusion 18 on the bottom surface of the pedal 10 abuts against the second pressure sensor 11 on the connecting seat 15 to achieve the test of the user's foot stepping force, and the structural design is simple and reasonable.

[0039] In one embodiment, the detection mechanism 2 further includes a locking member 19 and a plurality of guide rods 20. The fixed seat 4 is provided with a mounting groove 21. The plurality of guide rods 20 are detachably mounted in the mounting groove 21 along the extension direction of the fixed seat 4. The plurality of guide rods 20 all pass through the movable seat 5. A locking hole is provided on one side of the movable seat 5 at a position corresponding to the guide rod 20. The locking member 19 passes through the locking hole and is used to abut against the guide rod 20. Specifically, Figures 2 to 4As shown, the guide rods 20 can ensure the stability of the movement of the movable seat 5 in the installation groove 21, so that the movable seat 5 can stably contact with the first pressure sensor 6 to test the user's lower limb strength, and the use is reliable. Furthermore, during the operation of the rehabilitation training mechanism 3, by screwing the locking member 19 and making it contact with the guide rod 20, the rehabilitation training mechanism 3 and the movable seat 5 can be prevented from moving freely relative to the fixed seat 4, thereby ensuring the stability of the use of the rehabilitation training mechanism 3; at the same time, when the lower limb strength test is required, the locking member 19 can be screwed to disengage it from the guide rod 20 to meet the mobile test requirements of the movable seat 5, which is simple to operate and convenient to use.

[0040] In one embodiment, first pressure sensors 6 are respectively disposed on the two opposite groove walls of the mounting groove 21, and a flexible block 22 is disposed on the movable seat 5 at a position corresponding to the first pressure sensor 6; and a scale 23 is disposed on one side of the fixed seat 4 along its extension direction. It can be understood that, if Figure 3 and Figure 4 As shown, the flexible block 22 can be made of rubber or silicone material, so as to prevent the movable seat 5 from exerting too much impact on the first pressure sensor 6 and causing damage to the first pressure sensor 6, thereby extending the service life of the first pressure sensor 6. Furthermore, by setting the scale 23, it is convenient for medical staff to intuitively view the moving distance of the movable seat 5, thereby facilitating the judgment and testing of the user's lower limb strength and improving the accuracy of the test data.

[0041] In one embodiment, the clamping assembly includes two first clamping plates 24, which are respectively mounted on both sides of the slide 1 in a limited and movable manner, and the two first clamping plates 24 are respectively used to abut against the side walls of the bed 200. It can be understood that Figure 1 and Figure 2 As shown, the two first clamps 24 and the slide 1 can be installed in a limited and movable manner by a threaded connection (such as linear movement by screwing a screw), thereby allowing the two first clamps 24 to move closer to or farther away from each other relative to the slide 1, thereby not only being able to adapt to and be installed on beds 200 of different widths, thereby improving the flexibility of use of the elderly lower limb strength testing equipment 100 of the present invention, but also ensuring the stability of the installation of the slide 1 on the bed 200.

[0042] In another embodiment, the clamping assembly includes a first clamping plate 24 and a second clamping plate 25. The first clamping plate 24 is arranged on one side of the slide 1 and can be limitedly moved along the extension direction of the slide 1; the second clamping plate 25 is arranged relative to the first clamping plate 24 and can be limitedly moved along the height direction of the slide 1, and a limiting boss is formed on the side of the second clamping plate 25 facing the first clamping plate 24.

[0043] Understandably, if Figure 1 and Figure 2As shown, when the slide 1 needs to be installed on the bed body 200, the medical staff will make the side of the second clamping plate 25 with the limited boss abut against the bed body 200. The second clamping plate 25 can be installed to one side of the slide 1 by means of a screw or the like, and the second clamping plate 25 can be moved along the height direction of the slide 1, so that the medical staff can make the limited boss on the second clamping plate 25 abut against the bed body 200 by screwing the screw, so as to achieve the limit in the height direction of the slide 1; at the same time, when the second clamping plate 25 is adjusted, After being in place, since the first splint 24 is arranged on one side of the slide 1 and can be limited and moved along the extension direction of the slide 1, the first splint 24 and the slide 1 can also be installed in a screw manner, thereby allowing medical staff to screw the screw on the first splint 24 to move the first splint 24 in the direction close to the second splint 25 until it abuts against the bed body 200, thereby achieving the limitation of the length direction of the slide 1 and firmly installing the slide 1 on the bed body 200, which is simple to operate and easy to use.

[0044] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
