Description

Technical Field

[0001] The utility model relates to the technical field of tissue tension measurement, in particular to a tissue tension measurement device. Background Art

[0002] The human body has many kinds of tissues, which are important components of the human body. Taking muscles among various tissues as an example, all physiological activities of human beings require the participation of muscles to achieve, and muscle damage or disease will seriously affect people's normal life.

[0003] Muscle tone refers to an involuntary, continuous, and tiny contraction of muscle tissue in a resting state (i.e., relaxed muscle state). Muscle tone is the basis for maintaining various body postures and normal activities (such as sitting and standing). Abnormal muscle tone is a common manifestation of many neurological and muscular diseases. In the fields of medicine and rehabilitation, accurate assessment of muscle tone is crucial for diagnosis, treatment, and rehabilitation. Muscle tone index parameters can help doctors and therapists understand the patient's muscle status and guide the formulation of subsequent treatment plans.

[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 subjective influence of the operator. The isokinetic tester method can objectively and quantitatively evaluate spasticity, but due to the complex operation and large equipment, it requires professional training to be proficient in use, which increases the learning cost and usage threshold, and has not been widely used in clinical practice. Manual muscle tension assessment is based on the grasping of the tested muscles, relying on one's own experience and judgment to feel the tension of the muscles. This method also relies on the subjective judgment and experience of the operator, resulting in the consistency and objectivity of the results being affected, and automatic data analysis and calculation cannot be achieved. In addition, due to the lack of a unified standard, there are also problems of low precision or unstable measurement results, which affects the accuracy and repeatability of the assessment.

DETAILED DESCRIPTION

[0024] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0025] The embodiment of the utility model provides a tissue tension measuring device. The tissue tension measuring device can be used to measure the tension of various tissues such as muscle, skin (e.g., edematous tissue of lymphedema patients), so it can play a vital role in the fields of medical treatment and rehabilitation. The tissue tension measuring device of the embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1-3 As shown, the tissue tension measurement device may include a main housing 100 , a pressing assembly 200 , a control module 310 , a wireless transmission module 320 , and a power supply module 330 .

[0027] The main body shell 100 can be used as the base of the tissue tension measuring device. The shape of the main body shell 100 can be arbitrary. The main body shell 100 can be made of materials such as plastic.

[0028] One end of the pressing component 200 can be connected to the main housing 100 by any suitable means such as plugging, clamping or connecting piece connection. The other end of the pressing component 200 can be located outside the main housing 100 to press the tissue and measure the pressure on the tissue and the displacement along the pressing direction. That is to say, the pressing component 200 can extend from the main housing 100 to the outside of the main housing 100 along the pressing direction. The pressing direction can be perpendicular to the tissue. The tissue includes but is not limited to muscles. Among them, the muscle can be the biceps femoris, triceps femoris, gastrocnemius, rectus femoris, tibialis anterior, gastrocnemius medial head or gastrocnemius lateral head, etc. The pressing component 200 can measure the tissue by any suitable means such as vision. The pressing component 200 can measure the tension of the tissue in different states. Exemplarily, for muscles, the pressing component 200 can measure the pressure on the tissue in the relaxed state and the contracted state and the displacement along the pressing direction respectively. Since the area of ​​the other end of the pressing component 200 is smaller, it can be used to measure the pressure exerted on smaller tissues (such as a single muscle) and the displacement along the pressing direction.

[0029] The control module 310, the wireless transmission module 320 and the power supply module 330 can all be disposed in the main housing 100. Figure 2 In the illustrated embodiment, a circuit main board 350 may be further disposed in the main housing 100. The power supply module 330 may be disposed on the circuit main board 350. Of course, the control module 310 and the wireless transmission module 320 may also be disposed on the circuit main board 350.

[0030] The control module 310 can be used to receive the electrical signal sent by the pressing component 200, and perform analysis and calculation to generate measurement results. The measurement results may include a "force-displacement" curve and a data file. Exemplarily, for the data file, it can be the maximum displacement value of the "force-displacement" curve in the relaxed state and the contracted state, the area under the curve, and the area difference between the two. The data file may also include the tissue state further calculated based on the above calculation results. Taking muscle as an example, when the pressing component 200 presses the tissue along the pressing direction, the muscle will deform. The "force-displacement" relationship that occurs during this deformation process can quantitatively evaluate the muscle tension of the part. When the muscle is relaxed, the muscle compliance is high, the deformation is large, the resistance encountered when pressing it is small, and the displacement is large; on the contrary, when the muscle is stiff, the muscle compliance is low, the resistance encountered when pressing it is large, and the displacement is small. The control module 310 can develop an efficient data processing algorithm, so that the pressure data and displacement data can be collected in real time at a rate of 2000 points per second to ensure accurate collection of detailed changes in tissue tension deformation. For example, the control module 310 may use any suitable data processing algorithm, such as a data processing algorithm based on fuzzy logic or neural network, to accurately extract, analyze and record tissue tension data, so that doctors and therapists can analyze and track changes in tissue tension.

[0031] The electrical signal may include any suitable signal such as a voltage signal. The wireless transmission module 320 may be used to wirelessly transmit the measurement result to the display panel 500. The wireless transmission module 320 includes but is not limited to a WiFi module, a Zigbee module, a Bluetooth module or an infrared module. The power supply module 330 may be used to power the pressing component 200, the control module 310 and the wireless transmission module 320. The power supply module 330 includes but is not limited to a battery. Figure 2 In the illustrated embodiment, a power converter 340 may be further disposed in the main housing 100. The power supply module 330 may supply power to the pressing assembly 200, the control module 310 and the wireless transmission module 320 through the power converter 340. The power converter 340 includes but is not limited to a DC-DC converter.

[0032] In actual application of the tissue tension measuring device, the subject can be in a supine position, and the tissue tension measuring device can be located at the tissue to be measured. The operator can hold the main housing 100 to press the tissue along the pressing direction through the pressing component 200. Exemplarily, the pressing component 200 can be pressed quickly (for example, less than 1 second) toward the tissue along the pressing direction to a predetermined force (for example, 2KG), and then lifted to separate the pressing component 200 from the tissue. In some embodiments, a sound prompter can be provided in the tissue tension measuring device. When the sound prompter makes a sound, the tissue tension measuring device can be lifted.

[0033] In the process of the pressing component 200 slowly applying force to the tissue along the pressing direction, the pressing component 200 can measure the pressure on the tissue and the displacement along the pressing direction in real time, and send an electrical signal. When the predetermined force is pressed, the measurement ends. The control module 310 can receive the electrical signal sent by the pressing component 200, and perform analysis and calculation to generate the measurement result. Then, the wireless transmission module 320 can wirelessly transmit the measurement result to the display panel 500. The measurement result can be displayed on the display panel 500 for the convenience of the operator to watch and subsequent analysis. The operator can also open the data analysis software (such as MTIMS software) through the display panel 500, so that the measurement results can be further analyzed, processed and stored to support clinical decision-making. The display panel 500 can inform the patient in real time and intuitively through the data, which can effectively avoid the doctor-patient conflict caused by the patient's questioning of the effect. The display panel 500 can be any suitable display panel, such as a display panel with touch screen technology or voice recognition technology, to meet the needs of different user groups.

[0034] In summary, the tissue tension measuring device provided by the embodiment of the utility model adopts automated measurement, thereby eliminating the influence of human subjective factors, and thus providing objective, consistent and digitally quantified tissue tension measurement results. Through advanced data processing technology, more accurate and repeatable tissue tension measurement can be achieved, so that more reliable and effective tissue tension measurement solutions can be provided for fields such as medical treatment and rehabilitation. The structure of the tissue tension measuring device is relatively small, so it can be easily operated with one hand, so it is very convenient to use. In addition, the tissue tension measuring device is simple and easy to use, easy to operate, and does not require complex equipment or professional skills, making it suitable for various scenarios in clinical practice (including hospitals, rehabilitation centers and home care). In addition, since it is equipped with a power supply module 330, the tissue tension measuring device does not need to be connected to an external power supply through a power cable. Since it is equipped with a control module 310 and a wireless transmission module 320, it does not need to be connected to components such as a display panel 500 through a data cable. Therefore, the tissue tension measuring device can be conveniently used at any time in clinical practice and has strong applicability.

[0035] Based on the above advantages, the tissue tension measurement device can improve the efficiency of tissue tension measurement and reduce costs. It is estimated that the annual usage frequency of a single device can reach 5000-12960 times.

[0036] The tissue tension measuring device can have a variety of clinical values, such as evaluating the effect and / or efficiency of clinical intervention (training, drug therapy, etc.); guiding the intensity, frequency, dosage and interval of treatment; measuring the tension and elasticity of myofascial tissue; evaluating the abnormal degree of muscle tension or other tissue tension; evaluating the degree of tissue damage and recovery, and evaluating and measuring changes in muscle mechanical properties. The tissue tension measuring device can timely and accurately evaluate the clinical treatment and training effects, and promptly correct unreasonable and inappropriate treatment methods or training methods. In this way, the effectiveness of rehabilitation treatment can be greatly enhanced, saving a lot of social cost investment, and the time investment of patients and doctors. The tissue tension measuring device can be applied to various diseases, such as stroke, spinal cord injury, cerebral palsy, sports injury, lymphedema, Guillain-Barré and Parkinson's disease.

[0037] Exemplarily, the pressing assembly 200 may include a pressing rod 210, a pressure acquisition sensor 220, a sleeve 230, an elastic member, and a displacement acquisition sensor 240. The pressing rod 210 may extend from the inside of the main housing 100 to the outside of the main housing 100 along the pressing direction for pressing tissue. The pressure acquisition sensor 220 may be disposed in the main housing 100. Furthermore, the pressure acquisition sensor 220 may be used to collect the pressure received by the pressing rod 210 and send an electrical signal of the pressure to the control module 310. The sleeve 230 may extend from the inside of the main housing 100 to the outside of the main housing 100 along the pressing direction for pressing tissue. The sleeve 230 may be sleeved on the pressing rod 210 and movable along the pressing direction. The displacement acquisition sensor 240 may be disposed in the main housing 100. Furthermore, the displacement acquisition sensor 240 may be used to collect the displacement of the sleeve 230 and send an electrical signal of the displacement to the control module 310. The elastic member may be connected to the sleeve 230. The elastic member can apply an elastic force along the pressing direction to the outside of the main housing 100 to the sleeve 230. The elastic member includes but is not limited to an elastic member made of a spring or rubber or other materials.

[0038] The operator can hold the main housing 100 to press the tissue along the pressing direction through the pressing rod 210 and the sleeve 230. In this way, the pressure acquisition sensor 220 can determine the pressure on the tissue by collecting the pressure on the pressing rod 210. After the electrical signal of the pressure is amplified and collected, the electrical signal of the pressure can be sent to the control module 310. At the same time, when the pressing rod 210 presses the tissue, the tissue at that place will be concave, while the tissue at the sleeve 230 will not be concave. In this way, the sleeve 230 can move toward the main housing 100 along the pressing direction relative to the pressing rod 210. In this way, the displacement acquisition sensor 240 can determine the displacement of the tissue by collecting the displacement of the sleeve 230. After the electrical signal of the displacement is amplified and collected, the electrical signal of the displacement can be sent to the control module 310. The control module 310 can analyze and calculate based on the electrical signal of the pressure and the electrical signal of the displacement to generate a measurement result. By using high-precision sensors and advanced data processing technology, the tissue tension measurement device of the utility model can achieve more accurate and repeatable tissue tension measurement, thereby improving the accuracy of diagnosis and treatment. When the sleeve 230 moves relative to the pressing rod 210 in the pressing direction toward the main housing 100, the elastic member can be compressed. When the pressing rod 210 is separated from the tissue, the elastic member can release elastic potential energy, so that the sleeve 230 can move relative to the pressing rod 210 in the pressing direction away from the main housing 100 to restore the original position, thereby preparing for the next measurement.

[0039] The sensor used in the present invention can be any suitable sensor, such as an optical sensor, an acoustic sensor, etc., to achieve the above functions. Therefore, the use of different types of sensors and the adaptation of data processing algorithms should also be included in the protection scope of this application.

[0040] Exemplarily, a protrusion 231 may be provided on the sleeve 230. A groove may be provided on the displacement acquisition sensor 240. As the sleeve 230 moves, the protrusion 231 may move in the groove along the pressing direction. The displacement acquisition sensor 240 is used to collect the displacement of the protrusion 231, thereby determining the displacement of the sleeve 230. In this way, the structure of the tissue tension measuring device is relatively simple, and the groove can guide the protrusion 231.

[0041] Exemplarily, a pressing pad 250 may be provided on the end of the pressing rod 210 for pressing tissue. The pressing pad 250 may ensure that the subject has good comfort when pressing tissue.

[0042] Exemplarily, an annular pad 260 may be provided on the end of the sleeve 230 for pressing the tissue. The annular pad 260 may be sleeved on the pressing rod 210. The area of ​​the annular pad 260 along a plane perpendicular to the pressing direction may be larger than the area of ​​the sleeve 230. In this way, the sleeve 230 exerts less pressure on the tissue, thereby avoiding the tissue from being sunken, which in turn causes inaccurate displacement measurement.

[0043] Exemplarily, the annular support 260 can be a transparent member. The annular support 260 can be made of materials such as resin glass. In this way, the operator can easily observe the pressed tissue.

[0044] Exemplarily, the tissue tension measuring device may further include an extension rod 270. The extension rod 270 may be located inside the main housing 100. Furthermore, the extension rod 270 may be coaxial with the pressing rod 210. The pressure acquisition sensor 220 may be connected between the extension rod 270 and the pressing rod 210. The sleeve 230 may also be sleeved on the extension rod 270. By providing the extension rod 270, the sleeve 230 has better guidance. Furthermore, the pressure acquisition sensor 220 is relatively closer to the tissue to reduce the influence of the lateral force perpendicular to the pressing direction on the measured pressure when the tissue is pressed.

[0045] Exemplarily, the main body housing 100 may include a head end 110 and a grip 120. The head end 110 and the grip 120 may be connected to each other along the pressing direction. The head end 110 and the grip 120 may generally be an integral piece. The control module 310, the wireless transmission module 320, and the power supply module 330 may all be disposed in the head end 110. One end of the pressing assembly 200 may be connected to the grip 120. The other end of the pressing assembly 200 may be located outside the grip 120. The head end 110 and the other end of the pressing assembly 200 may be disposed opposite to each other along the pressing direction. The operator may hold the grip 120 to press the tissue. The size of the head end 110 may be relatively large, so that it may be convenient to hold components such as the control module 310, the wireless transmission module 320, and the power supply module 330. The shape of the grip 120 may be adapted to the operator's hand to improve the feel of holding.

[0046] Exemplarily, a switch 410, an indicator light 420 and a charging interface 430 may be provided on the end surface of the other end of the head end 110 facing away from the pressing component 200. The switch 410 may be used to control the tissue tension measuring device to be turned on and off. The switch 410 may be any suitable switch such as a toggle switch. The indicator light 420 may be used to display the status of the tissue tension measuring device. Exemplarily, when the indicator light 420 is green, the tissue tension measuring device is in the on state. An external power source may be connected to the charging interface 430. The charging interface 430 may be electrically connected to the power supply module 330 to charge the power supply module 330. The charging interface 430 may also be electrically connected to the pressing component 200, the control module 310 and the wireless transmission module 320 to directly power the pressing component 200, the control module 310 and the wireless transmission module 320. In the embodiment where a power converter 340 is disposed in the main housing 100, the charging interface 430 can be electrically connected to the pressing assembly 200, the control module 310 and the wireless transmission module 320 through the power converter 340. The charging interface 430 includes but is not limited to any suitable interface such as Type-c.

[0047] Exemplarily, a display panel 500 may also be provided on the head end portion 110. In this way, the tissue tension measuring device has more functions and a better user experience.
