Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a medical muscle hardness measuring instrument. Background Art

[0002] Rehabilitation treatment diagnosis and sports medicine have both serious medical and consumer attributes. They mainly target sports-related soft tissue problems, including surgery and sports rehabilitation guidance diagnosis, and have great clinical significance.

[0003] Ordinary sports rehabilitation products are mostly based on sports mechanisms, and the mechanical feedback applied during exercise is used as a measurement and diagnostic indicator of sports health. The product mechanism is complex and large, and the feedback data is a dynamic muscle force assessment, but it is unable to measure the static (natural state) hardness of muscles and quantitatively measure abnormal muscle hardness.

[0004] As for some existing muscle strength testers, muscle strength is measured by active muscle force rather than by quantitative measurement of muscle hardness in static state (natural state).

[0005] Existing products with designated motion mechanism functions have complex product structures and large overall volumes, making it impossible to achieve product miniaturization and inconvenient to use in small-space rehabilitation hospital outpatient clinics.

[0006] Patients are required to actively exert force in a specific direction to calculate muscle strength. For weak patients with movement disorders or who are unable to exert specific force, such as people with motor disabilities and the elderly lying in hospital beds, it is basically impossible to meet the above-mentioned active movement requirements and thus complete the measurement and diagnosis.

[0007] In addition, for products that actively exert force, they all measure muscle strength based on exerting force in a specific direction. This muscle strength is the overall tensile or compression load-bearing method of the muscle, which is the overall strength of certain muscles. There is a lack of measurement of changes in the local hardness of a certain muscle. Utility Model Content

[0008] The purpose of this application is to provide a medical muscle hardness measuring instrument that can miniaturize the product volume and detect changes in local muscle hardness without the tester having to exercise or actively exert force.

[0009] In order to achieve the above-mentioned object, the utility model provides a medical muscle hardness measuring instrument, comprising a main unit and a diagnostic head, wherein the diagnostic head is separately arranged from the main unit, the main unit comprises a shell, the shell is provided with a receiving groove for placing the diagnostic head, and a charging contact is arranged inside the receiving groove;

[0010] The diagnostic head comprises a handle, a contact head is arranged at the front end of the handle, the contact head is connected to a detection spring located inside the handle, and the detection spring is connected to a displacement sensor.

[0011] In an optional embodiment, a detachable end cover is provided at the front end of the handle, the contact head is detachably mounted on the handle, and the contact head extends outward from the end cover and protrudes from the end cover.

[0012] In an optional embodiment, the end caps and the contact heads include multiple pairs, and the shell is also provided with a spare parts storage groove for storing the end caps and the contact heads. The spare parts storage groove is arranged at the front bottom of the shell, and a front flip cover is arranged at the bottom of the spare parts storage groove.

[0013] In an optional embodiment, the receiving slot is disposed on the top or side of the housing, and when located at the top of the housing, the receiving slot includes a vertical slot hole with an open top, so that the diagnostic head can be placed vertically;

[0014] When located at the side of the shell, the accommodating groove is provided with a flip frame including a side plate, and the flip frame can be opened and closed on the shell through a hinge.

[0015] In an optional implementation, a display screen is disposed on the host, a host circuit board is disposed inside the shell, and the display screen is electrically connected to the host circuit board via a data cable.

[0016] In an optional embodiment, a fixing plate is provided on the side of the shell, the display screen is detachably mounted on the fixing plate, and a plurality of threaded holes are provided on the fixing plate.

[0017] In an optional embodiment, the diagnostic head includes a detection circuit board located inside the handle, a detection control unit is provided on the detection circuit board, the displacement sensor is electrically connected to the detection control unit, and a diagnostic head communication module is provided on the detection circuit board.

[0020] In an optional embodiment, the charging contact includes a USB or type-C plug connector, and the plug connector is connected to a data cable extending out of the housing.

[0021] Through the separately set diagnostic head and main unit, the diagnostic head can directly measure the hardness of naturally relaxed local muscles, timely diagnose local muscle abnormalities and local muscle lesions, and at the same time assist in the treatment of local muscles to determine the treatment effect.

[0022] By providing a receiving groove for placing the diagnostic head on the shell of the main unit, the diagnostic head separated from the main unit can be hidden and stored, the structure of the product can be optimized, and the product volume can be reduced. By simplifying the structure of the equipment, the product volume can be miniaturized, which can facilitate clinical diagnosis.

[0023] When the diagnostic head detects muscle hardness, the contact head at the front end of the diagnostic head handle touches and presses the detection part. Combined with the detection spring located inside the handle connected to the contact head, and the displacement sensor connected to the detection spring, the force value of the spring under compression and deformation and the displacement size obtained by the displacement sensor can be correlated.

[0037] See also Figure 1-Figure 4 The medical muscle hardness measuring instrument in the present application mainly changes the structural form of the existing medical muscle hardness measuring equipment on the market, and reduces the size of the main body 1 and the diagnostic head 2 by separating the diagnostic head 2 from the main body 1, so that the overall product has the characteristics of miniaturization, transportation and easy use.

[0038] At the same time, since the diagnostic head 2 is an independent component that is inconvenient to store and easy to lose, the diagnostic head 2 is stored in the main body to achieve hidden storage of the product.

[0039] Combination Figure 1-Figure 4The medical muscle hardness measuring instrument in the utility model has a main structure including a host 1 and a diagnostic head 2. The diagnostic head 2 and the host 1 are specifically arranged in a separate and independent form. The diagnostic head 2 can touch and press the local muscle, detect the muscle pressure in an active pressing manner, and transmit the detected pressure value to the host 1 for analysis. The detection process can be achieved without the tester exercising or actively exerting force.

[0040] The host 1 includes a shell 11, on which is provided a receiving groove 12 for placing the diagnostic head 2, so as to realize the combined storage of the diagnostic head 2 on the host 1, so as to avoid the defect that the diagnostic head 2 has nowhere to be placed after being separated from the host 1. At the same time, it can reduce the overall occupied space, make the overall structure of the measuring instrument more concise, and facilitate storage and transportation.

[0041] The diagnostic head 2 includes a handle 21, and a contact head 22 is arranged at the front end of the handle 21. The hardness of the local muscle is detected by touching and pressing the detection part with the contact head 22. The contact head 22 is connected to a detection spring 23 located inside the handle 21, and the detection spring 23 is connected to a displacement sensor 24. During use, the force value of the compression and deformation of the detection spring 23 can be correlated with the displacement size obtained by the displacement sensor 24, so that the pressure value corresponding to the muscle hardness at the touch and pressure part can be further calculated, so as to truly feedback the hardness of the muscle at the detection part.

[0042] During specific use, the diagnostic head 2 can be connected to the host 1 for communication. The diagnostic head 2 can transmit the received displacement signal to the host 1 through the communication module, and the built-in module of the host 1 can calculate the muscle hardness of the detection part.

[0043] In order to improve the use effect, a charging contact is further provided inside the receiving groove 12 , and the charging contact can be in contact with the charging part of the diagnostic head 2 , so as to realize charging during the storage process.

[0044] The medical muscle hardness measuring instrument in the utility model is based on the principle of contact pressure sensing measurement. The contact head 22 at the front end of the diagnostic head 2 retracts and contracts after contacting the muscle part to obtain muscle hardness data. The measurement data of muscle hardness is transmitted to the host 1, and then the host 1 processes the received measurement data and displays it on the display screen 15. At the same time, the entire product can store the diagnostic head 2 in a hidden storage manner to enhance portability.

[0045] In one specific embodiment, in order to meet the usage requirements in different scenarios, the contact head 22 includes multiple replaceable forms. Specifically, a detachable end cover 25 is provided at the front end of the handle 21, and the contact head 22 is detachably mounted on the handle 21, and the contact head 22 extends outward from the end cover 25 and protrudes from the end cover 25.

[0046] The end cover 25 is detachably fixedly connected to the front end of the handle 21 , and the contact head 22 is movably mounted on the handle 21 under the connecting action of the detection spring 23 .

[0047] Furthermore, the end caps 25 and the contact heads 22 include a plurality of pairs, and the housing 11 is further provided with a spare parts storage slot 13 for storing the end caps 25 and the contact heads 22, and the spare parts storage slot 13 can facilitate the storage of the end caps 25 or the contact heads 22. The spare parts storage slot 13 is provided at the front bottom of the housing 11, and a front flip cover 14 is provided at the bottom of the spare parts storage slot 13, which is convenient for taking and replacing at any time after opening.

[0048] From the perspective of accommodating the diagnostic head 2 , the accommodating groove 12 is arranged on the top or side of the shell 11 , and can be specifically arranged according to different measuring instrument models and the composition structure of the shell 11 .

[0049] When the receiving slot 12 is located at the top of the housing 11 , the receiving slot 12 includes a vertical slot hole with an open top, so that the diagnostic head 2 can slide down from the top opening of the vertical slot hole and be placed vertically in the slot hole.

[0050] When the accommodating groove 12 is located on the side of the shell 11, a flip frame including a side panel is provided at the accommodating groove 12. The flip frame can be opened and closed on the shell 11 by a hinge. This arrangement can facilitate the hidden storage of the diagnostic head 2, making the overall measuring instrument more concise.

[0051] Preferably, the setting form of the flip frame can facilitate the integrative placement of the diagnostic head 2, and a push lock is provided on the flip plate. After the diagnostic head 2 is placed on the flip frame, it can be pushed inward and flipped so that the side panel is self-locked on the shell 11, and at the same time it is convenient for the diagnostic head 2 to slide sideways on the flip frame.

[0052] It should be noted that, in addition to being able to place spare parts and the diagnostic head 2, the accommodating slot 12 or the spare part storage slot 13 can also be used to place small portable devices such as handheld ultrasound, so as to facilitate the follow-up use of auxiliary equipment at any time.

[0058] The host 1 control unit is provided with a host 1 communication module, which is connected to the communication module of the diagnostic head 2 for communication, facilitating the transmission of detection data between the diagnostic head 2 and the host 1. Preferably, both the host 1 communication module and the diagnostic head 2 communication module are Bluetooth wireless transmission modules, facilitating real-time data exchange with the host 1, so that the diagnostic head 2 forms an independent component, which is convenient for the user to hold the device at any angle to measure a muscle of the subject.

[0059] From the perspective of storage and charging compatibility, in one specific form, the charging contacts include metal contact sheets, and a metal charging chip is provided on the handle 21 of the diagnostic head 2. When the diagnostic head 2 is stored, the metal charging chip on the handle 21 can be brought into contact with and fit the metal contact sheet.

[0060] A charging port is provided on the shell 11 of the host 1, and the metal contact piece is electrically connected to the charging port through a wire. By plugging the external charging cable into the charging port and combining the contact between the metal charging chip and the metal contact piece, a complete charging circuit is constructed, and charging can be performed in the storage state.

[0061] In another specific implementation form, the charging portion on the handle 21 is a charging interface, and the charging contacts include a USB or type C plug connector, which is connected to a data cable extending from the shell 11. Through this setting, measurement data can be transmitted while charging.

[0062] In addition to wireless communication data transmission, a wired connection can also be established between the diagnostic head 2 and the host 1. The two are connected by a wire, and the detection data of the diagnostic head 2 is output to the host 1, thereby realizing the display function of the mechanical measurement of the entire product.
