Description

Technical Field

[0001] The utility model relates to the field of medical detection equipment, in particular to a measuring instrument for measuring elbow joint muscle tension. Background Art

[0002] Muscle tone refers to the tension of muscles in a relaxed state. It is a complex reflex activity regulated and controlled by the extrapyramidal system of the brain. Any damage to the "r-loop" of the reflex arc will lead to changes in muscle tone. Muscle tone is the basis for maintaining various postures and normal movements of the body. It can be manifested in various forms. According to the different movement states of the human body, it can be divided into static muscle tone, postural tone and motor muscle tone. Clinically, the occurrence of various diseases can lead to increased or decreased muscle tone, such as progressive muscular dystrophy, peripheral neuropathy, cerebellar disease, spinal cord disease, pyramidal tract disease, extrapyramidal disease, etc. Muscle tone disorder will, to a certain extent, limit the patient's range of limb movement and affect the patient's normal life. The assessment of the degree of muscle tone disorder is the basis for formulating an individualized treatment plan.

[0003] The inventor of this application found that there are the following problems in the practical use process:

[0004] At present, in clinical practice, doctors mainly feel the impedance of muscles by touch and obtain the results through Ashworth scale assessment, but this method mainly relies on the subjective feelings of the examiner and lacks objectivity and standardization. The main methods of mechanically detecting muscle tension are biomechanical method and electromyography test method. The biomechanical method is an indirect measurement and cannot quantitatively analyze muscle tension. In addition, the electromyography test method is affected by factors such as body surface temperature and humidity, and has uncertainty. At present, when entering the rehabilitation period after elbow surgery, in addition, the way to test muscle tension is to use manual methods to test the muscle tension of the patient's elbow joint. This method is mainly judged by the doctor's quality experience and there is no substantial data standard. Therefore, some new doctors cannot make effective judgments. Therefore, when testing the patient's elbow muscle tension, it is necessary to design a measuring instrument for measuring elbow muscle tension, which is easy to operate and has high measurement accuracy, reducing the difficulty of detection and the cost of use.

[0005] Therefore, it is necessary to provide a measuring instrument for measuring elbow joint muscle tension to solve the above-mentioned technical problems. Utility Model Content

[0014] By adopting the above technical solution, since the pressure layer includes a pressure-bearing plate, a plurality of spherical soft bags are arranged inside the pressure-bearing plate. The plurality of spherical soft bags can improve the overall comfort while providing flexible pressure.

[0015] It is further provided that a plurality of springs are provided inside the pressure plate, and the plurality of springs are evenly and equidistantly arranged.

[0016] By adopting the above technical solution, since a plurality of springs are arranged inside the pressure plate, the elastic pressure can be increased by the plurality of springs, thereby ensuring a better fit between the detection mechanism and the skin.

[0017] It is further configured that the bottoms of the first holding ring and the second holding ring are both sewn with an adhesive layer, and the material of the adhesive layer is Velcro.

[0018] By adopting the above technical solution, since the bottoms of the first holding ring and the second holding ring are sewn with adhesive layers, the measuring instrument for measuring elbow joint muscle tension can be effectively installed on the upper arm and the forearm through the adhesive layer.

[0019] It is further provided that an inflation head is provided on one side of the adhesive layer.

[0020] By adopting the above technical solution, the inflation layer can be inflated through the inflation head.

[0021] It is further provided that the first holding ring and the second holding ring are connected via a connecting piece.

[0022] By adopting the above technical solution, the first holding ring and the second holding ring are integrated, and the connecting piece can hold the elbow joint, so that the measuring instrument for measuring the muscle tension of the elbow joint can detect the tension of the muscles around the elbow joint.

[0023] It is further provided that a support plate is provided between the plurality of detection mechanisms, and the material of the support plate is a flexible stainless steel material.

DETAILED DESCRIPTION

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show typical embodiments of the present invention.

[0036] See also Figure 1 , Figure 2 The detection mechanism 5 includes a flexible slide rail 501, a slide groove 502 is provided inside the flexible slide rail 501, a mounting block 503 is slidably connected inside the slide groove 502, a detection head 504 is arranged inside the mounting block 503, airbag tubes 505 are arranged on both sides of the mounting block 503, and an inflation tube 506 is connected to the outer end of the airbag tube 505. Therefore, the slide groove 502 can be configured through the flexible slide rail 501, and the slide groove 502 can effectively ensure that the mounting block 503 can slide normally, and when the mounting block 503 slides back and forth, the patient's elbow joint can be effectively detected, and at the same time, only a detection head 504 is needed to carry out a comprehensive detection.

[0037] See also Figure 1 , Figure 2 There are multiple detection mechanisms 5, and the multiple detection mechanisms 5 are arranged in a linear array. Therefore, the detection mechanism 5 can perform real-time detection on the entire elbow joint, ensuring the accuracy of the detection data, and the multiple detection mechanisms 5 will not interfere with each other.

[0038] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The pressure layer 3 includes a pressure plate 301, and a plurality of spherical soft capsules 302 are arranged inside the pressure plate 301, and the plurality of spherical soft capsules 302 are evenly and equidistantly arranged. The plurality of spherical soft capsules 302 can improve the overall comfort while providing flexible pressure, and the pressure surface of the spherical soft capsules 302 is large, which can wrap the entire upper arm or forearm.

[0039] Embodiment 2:

[0040] See also Figure 1 , Figure 2 , Figure 3 , Figure 4On the basis of the first embodiment, the utility model provides a technical solution: a pressure plate 301, a plurality of springs 303 are arranged inside the pressure plate 301, and the plurality of springs 303 are evenly and equidistantly arranged.

[0041] See also Figure 1 , Figure 2 The bottom of the first holding ring 1 and the second holding ring 2 are both sewn with an adhesive layer 8, and the material of the adhesive layer 8 is Velcro. Therefore, the measuring instrument for measuring the elbow joint muscle tension can be effectively installed on the upper arm and the forearm through the adhesive layer 8. Moreover, Velcro belongs to the existing non-adhesive adhesion technology, so it is relatively easy to use and easy to disassemble and assemble.

[0042] See also Figure 1 , Figure 2 An inflation head 11 is provided on one side of the adhesive layer 8, and the inflation layer 10 can be inflated through the inflation head 11. The gas can be effectively discharged through the inflation head 11 to facilitate subsequent disassembly operations.

At this time, the detection head 504 can perform tension detection on the patient's upper and lower arm muscles in an all-round manner, and digitize the tension situation for better subsequent treatment. Moreover, there is no need to install multiple detection heads 504, thereby better saving costs.

[0046] In addition, in order to allow the detection mechanism 5 to better contact the skin, a certain amount of pressure needs to be applied.

At this time, setting multiple springs inside the pressure layer can achieve the effect of applying pressure. In order to provide better comfort, the spring can be replaced with a spherical soft capsule. The material of the spherical soft capsule is silicone, so it will be more comfortable and can effectively avoid the stress discomfort of the spring.
