Description

Technical Field

[0001] The present invention relates to the technical field of lower limb strength testing, and particularly to a lower limb strength testing device for the elderly. Background Art

[0002] With the accelerating development of the global aging society, the health problems of the elderly have attracted increasing attention. In particular, the decline of lower limb strength has become an important factor affecting their quality of life. Insufficient lower limb strength not only leads to inconvenient movement but also may increase the risk of falls, which may in turn trigger serious health problems. Therefore, accurately assessing 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 devices on the market, but most of these devices are designed for healthy people and do not fully consider the special needs of the elderly. The elderly generally have pathological problems such as muscle atrophy, joint stiffness, and decreased balance ability. However, existing devices often lack sufficient safety protection measures during the testing process, which easily lead to accidental injuries during the testing process.

[0003] The applicant retrieved and obtained the following prior art. Specifically, the patent with the publication number CN118830849A discloses a protective lower limb muscle strength testing device, which includes a vertical support frame. Above the left side surface of the vertical support frame, a controller for identifying, analyzing, and comparing the action behavior characteristics of the human body is installed; above the right side surface of the installation frame, a camera for recording the action behavior characteristics of the human body is installed; on the upper surface of the vertical support frame, a first mode testing mechanism is installed, and the first mode testing mechanism includes a first test rod installed in a groove on the upper surface of the vertical support frame. This protective lower limb muscle strength testing device avoids the user from falling forward or backward during the testing process, facilitates the protection of the user during the testing process, and facilitates the third mode of lower limb muscle strength testing work. Therefore, multiple mode testing selections can be made according to the needs of the tester, improving the diversity of the testing modes of the testing device and meeting the selection needs of different users.

[0004] As can be seen from the above patent, although this protective lower limb muscle strength testing device can facilitate the protection of the user during the testing process and can make multiple mode testing selections according to the needs of the tester, in the actual use process, since the user needs to sit on the seat board for testing, and the elderly usually have problems with inconvenient legs and feet, they often need additional assistance (such as being supported by medical staff or adding other protective measures) to sit on or leave the seat board in the testing device. This not only reduces the usability but also increases the risk of accidental falls, and the use safety is poor; at the same time, the lower limb muscle strength testing devices in the prior art usually can only perform a single lower limb strength test on the elderly and are difficult to meet the use requirements for the rehabilitation training of the elderly, restricting the scope of use.

[0034] Embodiment 1:

[0035] The present invention provides a lower limb strength testing device for the elderly.

[0036] In an embodiment of the present invention, the lower limb strength testing device 100 for the elderly includes a sliding table 1, a detection mechanism 2, and a rehabilitation training mechanism 3. The sliding table 1 is detachably mounted on the bed body 200 through a clamping assembly. The detection mechanism 2 is disposed on the sliding table 1 and can move relative to the bed body 200 through the sliding table 1. The detection mechanism 2 includes a fixed seat 4 and a movable seat 5. First pressure sensors 6 are respectively disposed on opposite sides of the fixed seat 4. The movable seat 5 is installed between the two first pressure sensors 6 in a limited movement manner and is used to install the rehabilitation training mechanism 3;

[0037] The rehabilitation training mechanism 3 includes a support rod 7, a first driving assembly 8, and a second driving assembly 9. A pedal 10 is movably installed on the support rod 7, and a second pressure sensor 11 is disposed below the pedal 10. The first driving assembly 8 is used to drive the support rod 7 to rotate relative to the movable seat 5, and the second driving assembly 9 is used to drive the support rod 7 to rotate relative to the first driving assembly 8.

[0038] Specifically, as Figures 1 to 5As shown, in the lower limb strength testing device 100 for the elderly of the present invention, since the sliding table 1 is detachably mounted on the bed body 200 through the clamping assembly, the clamping assembly can be a snap or a jaw, etc. Thus, it is not only convenient to disassemble and assemble the sliding table 1, but also enables the sliding table 1 to be mounted on bed bodies 200 of different specifications and sizes, improving the versatility and flexibility of use. At the same time, the way the sliding table 1 drives the detection mechanism 2 to move can be a cylinder, a hydraulic cylinder, a screw drive mechanism or an electric push rod, etc., so that the detection mechanism 2 can move relative to the bed body 200 on the sliding table 1, and thus can adapt to the specific lying position of the elderly on the bed body 200. Not only does it not require the elderly to move their own positions to adapt to the detection mechanism 2, making it more convenient and comfortable to use and improving the user experience, but it can also meet the use requirements of the elderly of different heights and body sizes, enhancing the applicability. In summary, during the use of the lower limb strength testing device 100 for the elderly of the present invention, for the elderly or the user group with inconvenient legs and feet, the user only needs to lie on the bed body 200 to perform the lower limb strength test, and the sliding table 1 can make the detection mechanism 2 move and adapt to the specific lying position of the user, without the user having to adjust their own position or posture, thus greatly improving the convenience of use, reducing the risk of accidental falls during the test, and reducing the probability of secondary injuries to the user due to the lower limb strength test, ensuring the safety of use.

[0039] Furthermore, since the detection mechanism 2 is arranged on the sliding table 1, specifically, the fixed seat 4 in the detection mechanism 2 can be mounted on the sliding table 1 by means of threaded connection, etc., which is convenient for disassembling and assembling the entire detection mechanism 2 and is conducive to 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 limit-actively mounted between the two first pressure sensors 6, the limit-actively mounting method of the movable seat 5 and the fixed seat 4 can be a chute clamping, etc., that is, a chute is opened on the fixed seat 4, and the movable seat 5 is clamped in the chute and can slide relative to the fixed seat 4 along the extension direction of the chute, and the two first pressure sensors 6 are respectively located on the opposite sides of the fixed seat 4, so that the movable seat 5 can abut against or separate from the two first pressure sensors 6, and the structural design is simple and reasonable.

[0040] Understandably, when it is necessary to test the lower limb strength of a user, after the medical staff adjusts the detection mechanism 2 in place, at this time, the user's sole 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 the legs at this time, causing the rehabilitation training mechanism 3 to drive the movable seat 5 to move relative to the fixed seat 4. When the user straightens the legs or extends the legs to the extreme position, the movable seat 5 can abut against the first pressure sensor 6 away from the user. Through this first pressure sensor 6, the muscle strength of the user when extending the legs can be tested. The first pressure sensor 6 transmits the data to an external terminal device, thereby facilitating the medical staff to evaluate the lower limb strength level of the user when extending the legs. In addition, during the actual use of the lower limb strength testing device 100 for the elderly of the present invention, after the user's sole steps on the pedal 10, the user's sole can be firmly tied to the pedal 10 by installing straps on the pedal 10 (the straps are conventional and mature existing technologies, and their specific structures are not shown in the accompanying drawings of the specification) and other means, thereby preventing the user's sole from detaching from the pedal 10 during the test and affecting the test. Similarly, when the user contracts the legs, at this time, the rehabilitation training mechanism 3 and the movable seat 5 move in the direction close to the user, that is, the movable seat 5 can abut against the first pressure sensor 6 close to the user. Through this first pressure sensor 6, the muscle strength of the user when contracting the legs can be tested, so as to facilitate the medical staff to evaluate the lower limb strength level of the user when retracting the legs. To sum up, the lower limb strength testing device 100 for the elderly of the present invention can drive the movable seat 5 to abut against the two first pressure sensors 6 respectively through the user's leg extension and leg contraction actions, and thereby test the muscle strength of the user when extending and contracting the legs, which not only facilitates the medical staff to evaluate the lower limb strength of the user, but also realizes the comprehensive testing of the lower limb strength, with a wide testing range, convenient and reliable use.

[0041] It is worth noting that the pedal 10 and the support rod 7 can be movably installed by pin connection, that is, pins are installed on both sides of the pedal 10, so that the pedal 10 can rotate relative to the support rod 7. Since a second pressure sensor 11 is provided below the pedal 10, after the user's sole steps on the pedal 10, the user's sole can step on the pedal 10 and cause it to rotate 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 when the sole makes a stepping action, and further facilitate the medical staff to evaluate the lower limb strength of the user when stepping on the sole, further expanding the testing range and having strong applicability.

[0042] It should be noted that during the actual use of the lower limb strength testing device 100 for the elderly according to the present invention, when the user's sole steps on the pedal 10, the first driving component 8 in the rehabilitation training mechanism 3 can drive the support rod 7 to rotate relative to the movable seat 5, so as to drive the user's lower limbs to rotate relative to the upper limbs with the hip joint as the rotation point; at the same time, since the second driving component 9 in the rehabilitation training mechanism 3 can drive the support rod 7 to rotate relative to the first driving component 8, it can further drive the user's calf to rotate relative to the thigh with the knee joint as the rotation point, and when the first driving component 8 and the second driving component 9 operate synchronously, they can drive the user's sole to rotate relative to the calf with the ankle joint, thereby not only effectively increasing the range of motion of the hip joint, knee joint and ankle joint, promoting the secretion of joint synovial fluid in the elderly, improving joint flexibility and relieving joint stiffness, but also stimulating the contraction and relaxation of the lower limb muscles (such as quadriceps femoris, hamstring muscles, calf muscle groups), helping to enhance and restore muscle strength, meeting the use requirements of the elderly for rehabilitation training, and expanding the scope of use, enriching the use functions, having good economy and being worthy of promotion.

[0043] In one embodiment, the first driving component 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, and the other end of the connecting rod 12 is rotatably connected to the support rod 7 in a limited manner. Specifically, as Figure 3 and Figure 4 shown, the detachable mounting manner of the first driving member 13 and the movable seat 5 can be adopted as threaded connection, which is convenient for disassembling, replacing and maintaining the first driving member 13. Further, the first driving member 13 can be a motor. By sleeving one end of the connecting rod 12 on the power output end of the first driving member 13 by means of threaded connection or the like, the first driving member 13 can drive the connecting rod 12 to rotate relative to the movable seat 5. And since the other end of the connecting rod 12 is rotatably connected to the support rod 7 in a limited manner, the connecting manner of the connecting rod 12 and the support rod 7 in a limited rotation can be adopted as bolt connection or the like, 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 operates 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, and further increasing the range of motion of the hip joint, which is beneficial to the rehabilitation training of the lower limbs.

[0044] In one embodiment, the second driving component 9 includes a second driving member 14. The second driving member 14 is hinged to the connecting rod 12, and the power output end of the second driving member 14 is hinged to the support rod 7, so as to drive the support rod 7 to rotate away from or close to the connecting rod 12 through the second driving member 14. Specifically, as Figure 3 andFigure 4 As shown, the second driving member 14 can be a cylinder, a hydraulic cylinder, a motor screw drive mechanism, an electric push rod, etc. in the prior art. Since the second driving member 14 is hinged to the connecting rod 12 and the power output end of the second driving member 14 is hinged to the support rod 7, not only can the support rod 7 be supported by the second driving member 14 to prevent the support rod 7 from rotating relative to the connecting rod 12 randomly, but also the support rod 7 can be driven by the second driving member 14 to rotate, 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 and facilitating the rehabilitation training of the lower limbs.

[0045] In one embodiment, a connecting seat 15 is detachably mounted at 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 provided between the pedal 10 and the connecting seat 15. A limiting wall 17 is formed along the circumference on the top surface of the pedal 10, and a protrusion 18 is provided on the bottom surface of the pedal 10. A second pressure sensor 11 is provided at a position corresponding to the protrusion 18 on the connecting seat 15.

[0046] Specifically, as Figures 3 to 5 shown, the limiting wall 17 formed on the pedal 10 can position the user's foot sole, preventing the user's leg from detaching from the pedal 10 when the leg is extended or contracted, and the use is reliable. Further, 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. The spring has the characteristics of compact structure, easy material selection, and large elastic recovery force. When the user steps on the pedal 10, the pedal 10 can drive the user's foot sole to return to the initial position under the action of the elastic member 16. During this process, the user's foot sole rotates relative to the calf with the ankle joint, thereby increasing the range of motion of the ankle joint, enabling the user to perform rehabilitation training on the foot sole by repeatedly stepping on the pedal 10. It can be understood that when the user steps on the pedal 10, the test of the user's foot sole stepping force can be realized by the protrusion 18 on the bottom surface of the pedal 10 abutting against the second pressure sensor 11 on the connecting seat 15, and the structural design is simple and reasonable.

[0047] In one embodiment, the detection mechanism 2 further includes a locking member 19 and a plurality of guide rods 20. An installation groove 21 is formed on the fixed seat 4. The plurality of guide rods 20 are detachably mounted in the installation groove 21 along the extending direction of the fixed seat 4, and the plurality of guide rods 20 all pass through the movable seat 5. A lock hole is provided on one side of the movable seat 5 corresponding to the position of the guide rods 20. The locking member 19 passes through the lock hole and is used to abut against the guide rods 20. Specifically, as Figures 2 to 4As shown, several guide rods 20 can ensure the smooth movement of the movable seat 5 in the installation groove 21, enabling the movable seat 5 to stably abut against the first pressure sensor 6 to test the user's lower limb strength, with reliable use. Further, during the operation of the rehabilitation training mechanism 3, at this time, by screwing the locking member 19 and making it abut against the guide rod 20, the relative movement of the rehabilitation training mechanism 3 and the movable seat 5 relative to the fixed seat 4 can be prevented, ensuring the use stability of the rehabilitation training mechanism 3; at the same time, when lower limb strength testing is required, screwing the locking member 19 to disengage it from the guide rod 20 can meet the movement test requirements of the movable seat 5, with simple operation and convenient use.

[0048] In one embodiment, first pressure sensors 6 are respectively arranged on the opposite two side walls of the installation groove 21, and flexible blocks 22 are arranged at the positions corresponding to the first pressure sensors 6 on the movable seat 5; a scale 23 is arranged on one side of the fixed seat 4 along its extending direction. It can be understood that, as Figure 3 and Figure 4 shown, the flexible blocks 22 can be made of rubber or silica gel materials, so as to prevent the impact force of the movable seat 5 on the first pressure sensor 6 from being too large and damaging the first pressure sensor 6, and extending the service life of the first pressure sensor 6. Further, by setting the scale 23, it is convenient for medical staff to visually check the moving distance of the movable seat 5, so as to facilitate judging and testing the user's lower limb strength and improving the accuracy of the test data.

[0049] In one embodiment, the clamping assembly includes two first clamping plates 24, and the two first clamping plates 24 are respectively installed on both sides of the sliding table 1 in a limited movement manner, and the two first clamping plates 24 are respectively used to abut against the side wall of the bed body 200. It can be understood that, as Figure 1 and Figure 2 shown, the installation method of the two first clamping plates 24 and the sliding table 1 in a limited movement manner can adopt threaded connection (such as linear movement by screwing the screw rod), so that the two first clamping plates 24 can approach or move away from each other relative to the sliding table 1, thus not only being able to adapt to and install beds 200 of different widths, improving the use flexibility of the lower limb strength testing device 100 for the elderly of the present invention, but also ensuring the installation stability of the sliding table 1 on the bed body 200.

[0050] 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 sliding table 1 and can move in a limited manner along the extending direction of the sliding table 1; the second clamping plate 25 is arranged opposite to the first clamping plate 24 and can move in a limited manner along the height direction of the sliding table 1, and a limiting boss is formed on the side of the second clamping plate 25 facing the first clamping plate 24.

[0051] It can be understood that, as Figure 1 and Figure 2As shown, when the sliding table 1 needs to be installed on the bed body 200, medical staff make the side of the second clamping plate 25 that forms the limiting boss abut against the bed body 200. The second clamping plate 25 can be installed on one side of the sliding table 1 by means of a screw or the like, and the second clamping plate 25 can move along the height direction of the sliding table 1, so that medical staff can make the limiting boss on the second clamping plate 25 abut against the bed body 200 by screwing the screw, thereby realizing the limit of the sliding table 1 in the height direction. At the same time, after the second clamping plate 25 is adjusted in place, since the first clamping plate 24 is arranged on one side of the sliding table 1 and can be limited and moved along the extension direction of the sliding table 1, the installation method of the first clamping plate 24 and the sliding table 1 can also adopt a screw. Thus, medical staff can make the first clamping plate 24 move towards the second clamping plate 25 until it abuts against the bed body 200 by screwing the screw on the first clamping plate 24, and then can realize the limit of the sliding table 1 in the length direction and firmly install the sliding table 1 on the bed body 200, with simple operation and convenient use.
