[0046] Please refer to figure 1 , figure 2 As shown, the embodiment of the present invention provides a dynamometer chair 10, which is used to measure the pedaling force of the human body, and can quantitatively study muscles such as the quadriceps femoris.
[0047] Through the size of the pedaling force, the aging degree of the leg muscles of the elderly is judged, and then the health status of the elderly is judged. The age of the elderly is over 60 years old. Of course, it is entirely possible for the dynamometer chair to be used to measure the aging degree of leg muscles of middle-aged people under the age of 60.
[0048] Specifically, the dynamometer seat 10 includes a seat body 11 and a pedal dynamometer 12 , the seat body 11 is used to support the human body, and the pedal dynamometer 12 is used to measure the pedal force.
[0049] The structure of seat body 11 can adopt prior art, and in the present embodiment, seat body 11 has seat back 110, seat surface 111 and fo...

[0060] Please refer to image 3 As shown, the second embodiment of the present invention provides a dynamometer seat 10, and the second embodiment is further improved on the basis of the first embodiment.
[0061] There will be some differences in the height of the tested persons, that is to say, when the tested persons are sitting on the dynamometer seat 10, the stretching range of the legs is different, which leads to different degrees of bending of the legs during the measurement, and in the process of measuring the pedal force In order to make the measurement more accurate, the bending angle of the leg needs to be controlled within a certain range.
[0062] In this embodiment, the supporting member 121 includes a fixed frame 124 and a sleeve 125, the fixed frame 124 is fixed on the seat body 11, the sleeve 125 is slidably sleeved on the fixed frame 124, and the gap between the sleeve 125 and the fixed frame 124 is The space is fixed by the first locking piece 126 , and th...

Abstract
The invention relates to a force measuring seat for leg muscles, and belongs to the technical field of medical devices. The force measuring seat includes a seat body and a pedalling force measuring device; the pedalling force measuring device includes two pedalling force measuring assemblies; two pedalling force measuring assemblies are fixed on the seat body side by side. Each pedalling force measuring assembly includes a support part, a dynamometer and a pedal plate; the support parts are fixed with chair legs of the seat body; the dynamometers are inclinedly arranged on the support parts; the pedal plates are fixed with the movable ends of the dynamometers and used for cooperating with feet. The force measuring seat is mainly used for measuring the aging degree of leg muscles of the elderly. A tested person sits on the seat body, feet pedal on the pedal plates, and the pedal plates push the movable ends of the dynamometers to move, so that the dynamometers can accurately measure thevalue of the pedalling force, and then quantitatively study quadriceps femoris and other muscles. The measurement method is simple and convenient, the measurement results are intuitive, the aging degree of the leg muscles of the elderly is judged according to the measurement results, and the basis is provided for the follow-up research or treatment.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a force-measuring chair for leg muscles. Background technique [0002] Muscle is mainly composed of muscle tissue. Muscle tissue consists of muscle cells (muscle fibers) and connective tissue. Muscle cells are elongated and fibrous in shape, so muscle cells are often called muscle fibers. Cells are rich in myofilament proteins, which make up thin and thick myofilaments. The lower limb muscles are divided into hip muscles, thigh muscles, calf muscles and foot muscles according to their location. [0003] In the process of human growth, at a certain age, the leg muscles will age with age, especially the aging of the leg muscles of the elderly is more obvious, and the degree of aging of the leg muscles is the key to judging the health status of the elderly an important indicator of . [0004] In the measurement of the prior art, only the general measurement ...
