Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and particularly to a muscle strength testing device for treatment. Background Art

[0002] With the development of modern medicine and sports science, muscle strength testing devices for treatment have been widely used in the fields of rehabilitation medicine, sports training, and muscle function assessment. Muscle strength testing, as an important means to evaluate muscle health and function, can provide key information such as muscle strength, endurance, and motor ability. Traditional muscle strength testing devices usually rely on simple force sensors or spring devices to test the muscle response by applying a fixed force. However, this design often has many limitations. It cannot accurately simulate the complex load changes in muscle training and cannot reflect the stability and uniformity of muscle force output. Therefore, it cannot meet the needs of high-precision evaluation and treatment.

[0003] Existing muscle strength testing devices mostly use linear loads or fixed resistances for testing. Although this design is simple, it ignores the dynamic changes of human muscles during actual training and rehabilitation. During training, the muscle force generation does not always present in a linear or single-resistance mode. Especially during high-intensity or progressive load training, the muscle force generation mode usually shows non-linear changes. Traditional devices cannot effectively simulate such complex load changes, resulting in test results that cannot accurately reflect the performance of muscles in real training or rehabilitation. For some rehabilitation patients or athletes, incorrect muscle strength assessment may lead to deviations in treatment plans and even cause muscle strains or over-fatigue.

[0004] Most traditional muscle strength testing devices fail to effectively consider the progression of resistance during training. Many devices use simple methods of increasing or decreasing force to adjust the resistance, ignoring the adaptation process of muscles to different loads at different training stages. During high-intensity training, muscles gradually adapt to the load changes and gradually increase their force output. However, the linear or single-resistance design of traditional devices cannot simulate this progressive load process, thus affecting the rehabilitation and training effects. Too fast or unstable load increase is likely to lead to sudden high-intensity resistance, thereby increasing the risk of muscle strain or over-fatigue, especially for patients with weak muscles or in the rehabilitation period.

[0005] During the muscle strength test, the change in the measured angle is also an important factor. However, most of the existing testing devices only focus on the change in the force value and ignore the mutual relationship between the angle and the force. In actual training, the force exerted by the muscle is closely related to the movement angle. Especially during the movement of the legs, knees and other parts, the angle change will directly affect the muscle's force generation effect. Therefore, the muscle strength test that ignores the angle change is likely to underestimate or overestimate the actual applied force and cannot accurately reflect the stability and uniformity of the muscle force output. Moreover, traditional devices have errors when measuring the angle and fail to effectively eliminate the deviation of the angle and force data caused by the deviation of the movement trajectory, resulting in inaccurate evaluation results.

[0006] Modern muscle strength testing devices need to have more accurate force and angle monitoring functions, be able to simulate the increase in progressive load, and at the same time provide a load curve with non-linear changes to avoid the errors and imbalance problems in traditional devices. Compared with the traditional linear design, the non-linear change of the electromagnet can more accurately simulate the progressive load process in muscle training, thus effectively avoiding sudden high-intensity resistance and reducing the risk of muscle injury.

[0007] Therefore, how to provide a muscle strength testing device for treatment is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0008] An object of the present invention is to provide a muscle strength testing device for treatment. The present invention controls the magnetic force of the electromagnet by the repulsion of the electromagnet poles, controls the magnitude of the electromagnet to adjust the magnitude of the repulsive force, and adjusts the muscle strength training intensity. The magnetic force of the electromagnet presents a parabolic change. The parabolic magnetic force change means that the magnetic force changes non-linearly with the position change or current adjustment; compared with the linear or single magnetic force intensity design, the parabolic change can more accurately simulate the progressive load in actual muscle training; the parabolic magnetic force curve can ensure that the increase in force is stable and there will be no sudden sharp change, avoiding high-intensity resistance that may cause muscle strain or over-fatigue; the adjustment of the repulsive force of the electromagnet can generate different training intensities through different current adjustments to adapt to different training stages and goals; by adjusting the magnitude of the magnetic force, different training modes can also be designed, such as enhancing explosive power, endurance and other muscle strength training effects.

[0009] By accurately measuring the tilt angle of the leg-rest curved plate and the applied force, the present invention can eliminate the errors caused by non-linear movements when the calf is lifted; traditional muscle strength tests often only focus on a single force value, while by simultaneously detecting the changes in the tilt angle and the applied force, more comprehensive and accurate data can be obtained to ensure the reliability of the evaluation results; since the calf of the tester deviates when lifted, the change in the tilted applied force can help more accurately reflect the true force applied to the piezoelectric film sensor; if only the applied force is measured and the angle change is ignored, the actual force exerted by the muscle may be underestimated or overestimated; by detecting the tilt angle and the magnitude of the applied force, the performance of the muscle during training or testing can be more realistically restored; the detection of the tilt angle can help evaluate the stability and uniformity of the muscle force output; at different angles, the muscle may exert force differently, and by analyzing the relationship between the angle and the force, the therapist can better understand whether the patient's muscle strength is balanced and whether there are muscle dysfunctions.

[0024] The beneficial effects of the present invention are:

[0025] The present invention controls the electromagnet to adjust the magnetic force of the electromagnet by the repulsion of the magnetic poles of the electromagnet, controls the magnitude of the repulsive force, and adjusts the muscle strength training intensity. The magnetic force of the electromagnet presents a parabolic change. The parabolic magnetic force change means that the magnetic force changes non-linearly with the position change or current adjustment. Compared with the design of linear or single magnetic force intensity, the parabolic change can more accurately simulate the progressive load in actual muscle training. The parabolic magnetic force curve can ensure that the increase in force is smooth and there will be no sudden sharp changes, avoiding muscle strains or excessive fatigue that may be caused by high-intensity resistance. The adjustment of the repulsive force of the electromagnet can generate different training intensities through different current adjustments to adapt to different training stages and goals. By adjusting the magnitude of the magnetic force, different training modes can also be designed, such as enhancing explosive power, endurance, and other muscle strength training effects.

[0026] The present invention can eliminate the error caused by the non-linear movement when the calf is lifted by accurately measuring the tilt angle of the leg-restraining curved plate and the applied force. Traditional muscle strength tests often only focus on a single force value, while by simultaneously detecting the changes in the tilt angle and the applied force, more comprehensive and accurate data can be obtained to ensure the reliability of the evaluation results. Since the calf of the tester will deviate when it is lifted, the change in the tilted applied force can help more accurately reflect the real force applied to the piezoelectric film sensor. If only the applied force is measured and the angle change is ignored, the actual force exerted by the muscle may be underestimated or overestimated. By detecting the tilt angle and the magnitude of the applied force, the performance of the muscle during training or testing can be more realistically restored. The detection of the tilt angle can help evaluate the stability and uniformity of muscle force output. At different angles, the muscle may exert force differently. By analyzing the relationship between the angle and the force, the therapist can better understand whether the patient's muscle strength is balanced and whether there are muscle dysfunctions.

[0043] A piezoelectric film sensor 1001 is fixedly arranged on the inner wall of the leg rest curved plate 10, and a rubber protective layer 1002 is fixedly arranged on the inner wall of the leg rest curved plate 10.

[0044] More specifically, the bottom seat unit includes a main sliding seat 12, a main moving platform 13, an auxiliary sliding seat 14 and an auxiliary moving platform 15. Among them, the main sliding seat 12 is fixedly installed on the auxiliary sliding seat 14, and the main sliding seat 12 and the auxiliary sliding seat 14 are arranged perpendicular to each other. The bottom of the main moving platform 13 is slidably installed on the top of the main sliding seat 12, the top of the main moving platform 13 is fixedly installed at the bottom of the lifting assembly 1, the bottom of the auxiliary moving platform 15 is slidably installed on the top of the auxiliary sliding seat 14, and the top of the auxiliary moving platform 15 is fixedly installed at the bottom of the lifting assembly 1.

[0045] The main moving platform 13 moves on the main sliding seat 12, driving the test disk 3 to adjust the position of the test disk 3. The auxiliary moving platform 15 moves on the auxiliary sliding seat 14, driving the table and chair 2 to move.

[0046] The lifting assembly 1 includes a main electric lifting rod 101, a connecting column 102 and an auxiliary electric lifting rod 103. Among them, there are two main electric lifting rods 101. The bottoms of the two main electric lifting rods 101 are fixedly installed on the top of the main moving platform 13. The bottom of the connecting column 102 is fixedly installed on the top of the main electric lifting rod 101. The top of the connecting column 102 is fixedly installed at the bottom of the test disk 3. The bottom of the auxiliary electric lifting rod 103 is fixedly installed on the top of the auxiliary moving platform 15, and the top of the auxiliary electric lifting rod 103 is fixedly installed at the bottom of the table and chair 2.

[0048] More specifically, the processing unit includes an external board 16, a mounting column 17, a controller 18, a display screen 19 and a button group 20. Among them, one end of the external board 16 is fixedly installed on the main sliding seat 12. The bottom of the mounting column 17 is fixedly installed on the other end of the external board 16. The bottom of the controller 18 is fixedly installed on the top of the mounting column 17. The display screen 19 is fixedly installed on the controller 18, and the button group 20 is fixedly installed on the controller 18.

[0049] Furthermore, the tester sits on the table and chair 2, brings the tested calf close to the leg-restraining curved plate 10, then binds the calf tightly with the restraint strap 11, and starts the controller 18. The training difficulty is controlled through the display screen 19 and the button group 20. In order to evaluate and monitor muscle strength more accurately, a muscle force sensor can be attached to the human muscle to better capture the force, pressure or movement exerted by the muscle in real time, thereby helping medical staff evaluate muscle function, judge the treatment effect or track the rehabilitation process.

[0050] When the tester raises the calf, the acting force of raising the calf is applied to the leg-rest curved plate 10 and the piezoelectric film sensor 1001. When the tester raises the calf, the calf does not rise in a straight line but deviates, and the effective acting force applied to the piezoelectric film sensor 1001 will be reduced, resulting in deviation in the evaluation and monitoring of muscle strength.

[0051] When the tester raises the calf, the calf does not rise in a straight line but deviates. The deviating acting force will take the main swivel 809 and the main swivel plate 8010 as the rotation axes, and the leg-rest curved plate 10 will be partially tilted. The leg-rest curved plate 10 applies the tilted acting force to the hydraulic telescopic sleeve 8012. The hydraulic telescopic sleeves 8012 located on both sides of the leg-rest curved plate 10 will expand and contract. The hydraulic oil inside the hydraulic telescopic sleeve 8012 on one side of the leg-rest curved plate 10 enters the deviation-measuring liquid box 803 through the first liquid delivery pipe 8014, the flexible liquid pipe 8015 and the second liquid delivery pipe 8016. The piston 805 displaces inside the deviation-measuring liquid box 803, compresses the deviation-measuring spring 804, the displacement of the piston 805 drives the displacement of the permanent magnet 806, and then the induction coil 808 senses the position change of the permanent magnet 806, so as to judge the magnitude of the tilted acting force and the tilt angle of the leg-rest curved plate 10; the hydraulic oil inside the hydraulic telescopic sleeve 8012 on the other side of the leg-rest curved plate 10 enters the deviation-measuring liquid box 803 through the first liquid delivery pipe 8014, the flexible liquid pipe 8015 and the second liquid delivery pipe 8016. The piston 805 displaces inside the deviation-measuring liquid box 803, the piston 805 stretches the deviation-measuring spring 804, the displacement of the piston 805 drives the displacement of the permanent magnet 806, and then the induction coil 808 senses the position change of the permanent magnet 806, so as to judge the magnitude of the tilted acting force and the tilt angle of the leg-rest curved plate 10.

[0052] By accurately measuring the tilt angle of the leg-rest curved plate 10 and the applied acting force, the error caused by the non-linear movement when the calf is raised can be eliminated; traditional muscle strength tests often only focus on a single force value, while by simultaneously detecting the changes in the tilt angle and the acting force, more comprehensive and accurate data can be obtained to ensure the reliability of the evaluation results.

[0053] Since the calf will deviate when the tester raises it, the change in the tilted acting force can help more accurately reflect the real force applied to the piezoelectric film sensor 1001; if only the acting force is measured and the angle change is ignored, the actual force exerted by the muscle may be underestimated or overestimated; by detecting the tilt angle and the magnitude of the acting force, the performance of the muscle during training or testing can be more realistically restored.

[0054] The detection of the tilt angle can help evaluate the stability and uniformity of muscle force output; at different angles, the muscle force may be different. By analyzing the relationship between the angle and the force, the therapist can better understand whether the patient's muscle strength is balanced and whether there are muscle dysfunctions.

[0055] The detection of the tilt angle and the acting force helps to quantify the muscle performance of patients during the rehabilitation process; for stroke patients or patients with sports injuries, the muscle recovery process is often accompanied by muscle strength imbalance or instability; by monitoring these changes, therapists can adjust the rehabilitation training plan to ensure that each muscle group receives appropriate stimulation and avoid unnecessary loads.

[0056] The accurate measurement of the tilt angle and the magnitude of the acting force can effectively avoid errors caused by equipment or posture changes. If the angle change is not considered, it may lead to an incorrect estimation of the training intensity, thereby increasing the risk of muscle fatigue or injury; real-time monitoring of the changes in the tilt angle and force value helps to precisely control the training intensity and ensure the safety of the training process.

[0057] For athletes or individuals with high-intensity training needs, by accurately measuring the tilt angle and the acting force, the changes in muscle strength at different angles can be better analyzed; this is very helpful for formulating a more targeted training plan, enhancing the specific direction of muscle strength, and improving sports performance.

[0058] The acting force for lifting the leg rest plate 10 is sequentially transmitted to the linkage rod 707, the electric telescopic plate 706, and the hexagonal prism 705, and then the hexagonal prism 705 drives the rotating column shaft 701 to rotate on the test plate 3. The force sensor 9 detects the force exerted by the muscle. The rotation of the rotating column shaft 701 drives the swing frame 702 to rotate, and the rotation of the swing frame 702 drives the abutting column 703 to slide along the swing chute 704. The abutting column 703 drives the electromagnets 601 to approach each other. The controller 18 controls the magnetic force of the electromagnets 601 to gradually increase from small to large and then gradually decrease from large to small, showing a parabolic increase and decrease.

[0059] The parabolic magnetic force change means that the magnetic force changes non-linearly with the position change or current adjustment; compared with the design of linear or single magnetic force intensity, the parabolic change can more accurately simulate the progressive load in actual muscle training.

[0060] The parabolic magnetic force curve can ensure that the increase in force is smooth and there will be no sudden sharp changes, which is particularly important for muscle strength training; a sudden high-intensity resistance may cause muscle strain or excessive fatigue, while the parabolic change allows the muscle enough time to adapt to the increasing load and reduces the risk of injury.

[0061] The repulsive force adjustment of the electromagnets 601 can generate different training intensities through different current adjustments to adapt to different training stages and goals; by adjusting the magnitude of the magnetic force, different training modes can also be designed, such as enhancing explosive power, endurance, and other muscle strength training effects.

[0062] Since the shape of the parabola may better match the natural mechanical performance of the human muscles, this design can adapt to the muscle strength and training needs of different users and provide a training plan that better suits individual differences.

[0063] Piezoelectric thin film sensors 1001, force sensors 9 and muscle strength sensors will capture the force, pressure or movement exerted by the muscles, and thus present the data for medical staff to evaluate muscle function, judge the treatment effect or track the rehabilitation progress on the display screen 19.

[0064] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
