Description

Technical Field

[0001] The utility model relates to the field of medical instruments, and in particular to a muscle tension testing device. Background Art

[0002] Muscles are an important part of the human body. All physiological activities of a person require the participation of muscles. Muscle damage or disease will seriously affect a person's normal life. Abnormal muscle tension is a common manifestation of many neurological and muscular diseases. Muscle tension evaluation is crucial for formulating treatment plans and evaluating treatment effects.

[0003] Muscle tension refers to the resistance felt when a limb is moved or a muscle is pressed. This resistance is generated by the physical properties of the tissue, the elasticity of the muscle or connective tissue, reflex muscle contraction, etc. Lesions on the neuromuscular reflex arc, tendon contracture, joint stiffness, etc. will affect the test results of muscle tension. The test of muscle tension should be carried out in a warm environment and a comfortable position, and the test subject should be as relaxed as possible.

[0004] The most commonly used method for evaluating muscle tension in clinical practice is the modified Ashworth scale. Although this method is simple and easy to use, the results are greatly affected by the subjectivity of the tester. The isokinetic tester method can objectively and quantitatively evaluate spasticity, but due to the complex operation and large equipment, it has not been widely used in clinical practice. Manual muscle tension assessment is based on the grasping of the tested muscle, relying on one's own experience and judgment to feel the tension of the muscle. This method is also greatly affected by the subjectivity of the tester and there is no unified standard.

[0005] Therefore, it is necessary to design a portable and accurate muscle tension testing device. Utility Model Content

[0057] A muscle tension testing device according to an embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0058] Reference Figures 1 to 7 As shown, a muscle tension testing device provided according to an embodiment of the utility model includes a strap 10 , a pressurized airbag 101 , an inflatable component 20 and a plurality of strain gauge sensors 102 .

[0059] The strap 10 is suitable for being wrapped around the patient's limbs, and specifically, is used for being wrapped around the muscles of the patient's limbs during testing.

[0060] The pressurized airbag 101 is disposed on the inner wall of the bandage 10 and is used to apply pressure to the patient's limbs.

[0061] The inflation component 20 is connected to the pressurized airbag 101 and is used to inflate or deflate the pressurized airbag 101 to adjust the pressure applied to the patient's limbs.

[0062] The plurality of strain gauge sensors 102 are disposed at intervals on the inner wall of the pressurized airbag 101 , and are used to measure the fluctuation of the muscle under the pressure applied by the pressurized airbag 101 , and convert the measurement results into electrical signals for output.

[0063] Based on the above, by wrapping the strap 10 around the patient's limbs, this design makes the device easy to wear and can adapt to limbs of different sizes, improving the convenience of use. By inflating or deflating the pressurized airbag 101 through the inflatable component 20, it is possible to achieve precise adjustment of the pressure applied to the patient's limbs. This adjustment capability ensures the accuracy of the test and can be personalized according to the needs of different patients. Multiple strain gauge sensors 102 are spaced apart on the inner wall of the pressurized airbag 101, which can accurately measure the fluctuations of the muscles during the pressurization process. This design not only improves the accuracy of the measurement, but also can capture the subtle dynamic changes of the muscles, providing more detailed data support for doctors or researchers. The utility model has a simple overall structure, is easy and quick to use, has reliable test results, is highly practical, and has a good use effect.

[0064] It is understandable that the muscles of the human body's limbs are not flat, and the curvature of each person's muscles is not consistent. Therefore, when in use, the pressurized airbag 101 is pressurized to make the strain gauge sensor 102 bend accordingly according to the curvature of the patient's muscles. At this time, the current position can be used as the initial data, and then, according to subsequent detection needs, corresponding detection operations are performed. For example: the pressurized airbag 101 continues to apply pressure to the arm, and the strain gauge sensor 102 is used to detect the data fed back by the patient's muscles at each pressure stage, and the corresponding muscle tension verticality is calculated at one time.

[0065] For example, when the position of the strain gauge sensor 102 is set to the initial data, the patient's limbs are bent actively or passively with the assistance of a doctor, so that the corresponding muscle tension value can be calculated based on the data fed back by the muscles after bending. The detection is convenient and diversified.

[0066] Preferably, in an embodiment of the present utility model, the inflation component 20 includes a connecting tube 201 and an inflation balloon 202 .

[0067] One end of the connecting tube 201 is connected to the pressurized airbag 101 .

[0068] The inflatable airbag 202 is connected to the other end of the connecting tube 201 and is used to inflate or deflate the pressurized airbag 101 .

[0069] In this way, the over-inflated balloon 202 inflates or deflates the pressurized balloon 101, making the operation process simple and intuitive. Medical staff or patients themselves can easily master the operation method without complex equipment or professional skills;

[0070] The design of the inflatable balloon 202 allows for instant pressure adjustment, and medical staff can increase or decrease pressure at any time as needed, thereby achieving an instant response to the patient's limbs. This immediacy is very important for muscle tension testing because it can help doctors quickly capture muscle responses during the test;

[0071] Compared with some inflatable components 20 that require power or complex control systems, the combination of the inflatable balloon 202 and the connecting tube 201 is more economical. This simple and effective design reduces the cost of the device, making it more suitable for medical institutions or home use. Since the inflatable balloon 202 and the connecting tube 201 are small and light, the entire muscle tension testing device is easier to carry. Medical staff can test patients at different locations, providing greater convenience for patients;

[0072] In summary, by adding the connecting tube 201 and the inflatable balloon 202 as the inflatable component 20, the muscle tension testing device is further improved in terms of ease of operation, immediacy, cost-effectiveness and portability, making the muscle tension test more efficient, flexible and economical.

[0073] According to an embodiment of the present invention, the connecting pipe 201 includes a main body portion 2011 , an air pipe portion 2012 and a cable portion 2013 .

[0074] One end of the main body 2011 is connected to the pressurized airbag 101 , and the interior of the main body 2011 is divided into adjacent gas channels 20111 and cable channels 20112 .

[0075] One end of the trachea is connected to the inflatable balloon 202 , and the other end is connected to the main body 2011 , and communicates with the gas channel 20111 .

[0076] One end of the cable portion 2013 is connected to the main body 2011 and the cable channel 20112 , and the other end is connected to the display 203 .

[0077] Thus, the separation design of the gas channel 20111 and the cable channel 20112 inside the main body 2011 ensures that the gas and the cable do not interfere with each other during the transmission process, thereby improving the transmission efficiency. The gas channel 20111 is used to transmit the airflow generated by the inflatable balloon 202, while the cable channel 20112 is used to transmit the electrical signal output by the strain gauge sensor 102. The isolation between the two effectively avoids signal interference and transmission loss. The connection design of the trachea part 2012, the inflatable balloon 202 and the main body 2011 makes the inflation process more convenient.

[0078] At the same time, medical staff can quickly adjust the pressure of the pressurized airbag 101 by operating the inflated airbag 202 to meet the test requirements. The design of the cable part 2013 enables the electrical signal output by the strain gauge sensor 102 to be transmitted to the display 203 in real time. Medical staff can intuitively observe the ups and downs of the muscle during the pressurization process, providing strong data support for diagnosis. At the same time, the use of the display 203 also simplifies the data processing process and improves work efficiency.

[0079] Preferably, in an embodiment of the present utility model, a pressure sensor 103 is provided in the pressurized airbag 101 , and the pressure sensor 103 is connected to the display 203 to detect the pressure value in the pressurized airbag 101 .

[0080] In this way, by arranging the pressure sensor 103 in the pressurized airbag 101, the pressure value in the airbag can be detected and monitored in real time. This function provides direct feedback to medical staff, allowing them to accurately understand and control the pressure applied to the patient's limbs. Accurate pressure control is crucial for muscle tension testing. The pressure sensor 103 can ensure the stability and consistency of pressure during the test, thereby improving the accuracy of the test. Medical staff can adjust the inflation volume of the inflatable balloon 202 in time according to the real-time feedback of the display 203 to achieve the ideal test pressure. The accuracy, safety and convenience of the test are improved. This design improvement provides medical staff with a more reliable and efficient testing tool.

[0081] Preferably, in an embodiment of the present invention, the plurality of strain gauge sensors 102 are spaced apart along the length direction of the strap 10 and extend along the width direction of the strap 10 .

[0082] In this way, by distributing multiple strain gauge sensors 102 at intervals along the length of the strap 10, comprehensive coverage and detailed monitoring of different parts of the patient's limbs can be achieved. This layout can capture the ups and downs of muscles in different positions, providing doctors or researchers with more complete and detailed muscle tension data. The design of the strain gauge sensor 102 extending along the width direction of the strap 10 ensures full contact between the sensor and the muscle surface, thereby improving the accuracy of the measurement data. This layout can better capture the subtle changes in the muscle during the pressurization process, providing more accurate data support for diagnosis.

[0083] Preferably, in one embodiment of the utility model, a Velcro male surface 104 is provided on the inner side surface of one end of the strap 10, and a Velcro female surface 105 is provided on the outer side surface of the other end of the strap 10, and the Velcro female surface 105 extends along the length direction of the strap 10, and the Velcro female surface 105 and the Velcro male surface 104 are adhered to each other.

[0084] Thus, by providing a Velcro male surface 104 at one end of the strap 10 and a Velcro female surface 105 extending along the length direction of the strap 10 at the other end, medical staff or patients can easily fix the strap 10 on the patient's limbs. The quick sticking and separation characteristics of the Velcro male surface and the Velcro female surface 105 make the wearing and adjustment process simple and quick, and improve the convenience of use;

[0085] At the same time, the design of the Velcro allows the strap 10 to adapt to limbs of different sizes. Whether it is a thinner arm or a thicker thigh, suitable fixation can be achieved by adjusting the Velcro sticking position. This highly adaptable feature allows the device to be suitable for a wider range of patient groups. The adhesion between the Velcro male surface 104 and the Velcro female surface 105 is strong, which can ensure that the strap 10 remains in a stable fixed state during the test. This helps to reduce test errors caused by loosening or displacement of the strap 10, and improves the accuracy and reliability of the test. As a reusable fixing method, Velcro has a long service life. Compared with disposable fixing straps, this design not only reduces the cost of use, but also reduces the generation of medical waste, and is environmentally friendly.

[0086] Preferably, in an embodiment of the present invention, one end of the binding strap 10 is connected to a bent portion 106 , and the bent portion 106 bends and extends upward.

[0087] In this way, the curved portion 106 connected to one end of the strap 10 is not only ergonomically designed, but its detachable design makes it more convenient and flexible when the strap 10 needs to be disassembled or adjusted.
