[0002] A pelvic floor muscle test is a medical test that evaluates the function of the pelvic floor muscles. The pelvic floor muscles are a group of muscles located at the bottom of the pelvis that are responsible for supporting the bladder, uterus, and rectum. A pelvic floor muscle test can be used to diagnose and evaluate pelvic floor muscle dysfunction, such as urinary incontinence and pelvic organ prolapse.

[0003] The pressure sensing detection device that measures the pelvic floor muscle strength through the natural cavity is one of the important means to evaluate pelvic floor disorder syndrome in the fields of gynecology, urology and rehabilitation. However, the existing products on the market are restricted by the basic design of the probe structure, circuit, and the location, number and distribution of the sensing points, and cannot fully cover the annular wall area and the top area of ​​the probe cylinder. This leads to the situation in clinical practice that after the tester inserts the handheld device probe into the vagina or anorectum, it is impossible to comprehensively measure the muscle strength indicators of various areas inside the vagina and anorectum, and it is necessary to repeatedly detect different positions of the cavity by applying external forces such as movement and rotation.

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] All terms (including technical and scientific terms) used in this application have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used here should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0052] For example, the terms "first", "second", etc. used in this application may be used in this document to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element.

[0053] For another example, the terms “include”, “comprising”, etc. used in this application indicate the existence of features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0054] As mentioned above, the existing products on the market are subject to the basic design of the probe structure, circuit, etc., as well as the position, quantity and distribution of the sensing points, and cannot fully cover the probe cylinder ring wall area and the top area of ​​the cylinder. This leads to the fact that in clinical practice, after the detector inserts the handheld device probe into the vagina or anorectal canal, it is impossible to comprehensively measure the muscle strength indicators of various areas inside the vagina and anorectal canal, and it is necessary to repeatedly detect different positions of the cavity by applying external forces such as movement and rotation. This detection method is not only complicated to operate, but also affects the accuracy of the pelvic floor muscle pressure detection results due to the action of external forces. Therefore, the pressure sensing detection device currently used to measure the pelvic floor muscle strength still has certain limitations in terms of detection accuracy. To this end, the present application proposes a pelvic floor muscle pressure detection device, which can improve the detection accuracy of the pelvic floor muscle pressure and meet the needs of high-precision pressure distribution measurement of the pelvic floor muscle.

[0055] Figure 1 is a schematic structural diagram of a pelvic floor muscle pressure detection device 100 according to an embodiment of the present application. Figure 2 is a three-dimensional isometric view of a pelvic floor muscle pressure detection device 100 according to an embodiment of the present application, Figure 3 FIG. 1 is a schematic diagram of the structure of a probe 1 of a pelvic floor muscle pressure detection device 100 according to an embodiment of the present application. Figures 1 to 3 As shown, the pelvic floor muscle pressure detection device 100 of this embodiment includes:

[0056] A probe 1, comprising a flexible housing 11, a pressure sensing module 13 and a pressure transmission module 12 arranged between the flexible housing 11 and the pressure sensing module 13, wherein the flexible housing 11 is formed with a tubular portion and a spherical portion, the spherical portion is convexly arranged on one axial side of the tubular portion, the pressure sensing module 13 is arranged on the inner side of the flexible housing 11, and the pressure sensing module 13 is provided with an ion-type pressure sensor array 131 corresponding to the position of the pressure transmission module 12 toward the outer side of the tubular portion and the spherical portion, so as to detect the pelvic floor muscle pressure transmitted through the pressure transmission module 12 when the probe 1 is placed in the object to be measured, and convert the pelvic floor muscle pressure into a sensing capacitance signal;

[0057] The handle 2 is connected to the probe 1 and includes a signal processing module 21. The signal processing module 21 is electrically connected to the pressure sensing module 13 to convert the sensing capacitance signal into a detection voltage signal and obtain the pelvic floor muscle pressure value based on the detection voltage signal.

[0058] In this embodiment, the flexible shell 11 refers to a shell made of a flexible material, such as silicone, thermoplastic elastomer (TPE), etc. It can be completely flexible or a structure with a certain degree of flexibility. The main feature of this shell is that it can be bent and deformed to a certain extent without breaking or being damaged, while maintaining its sealing and structural properties. In the pelvic floor muscle pressure detection device 100, the role of the flexible shell 11 is to provide an interface that contacts the pelvic floor muscle of the object being tested. Due to the complex anatomical structure of the pelvic floor muscle area and the large individual differences, the flexible shell 11 can better adapt to different physiological structures, provide a more comfortable detection experience, and ensure that the ionized pressure sensor array 131 can fit the pelvic floor muscle tightly, thereby improving the accuracy and reliability of the detection.

[0059] The flexible shell 11 made of medical grade flexible material not only has good biocompatibility, but also has certain strength and durability, and can withstand repeated use and disinfection. In some embodiments, the flexible shell 11 can be designed as a single-use product. Before each test, only a new flexible shell 11 needs to be replaced to ensure the sterility and accuracy of the device.

[0060] Figure 4 FIG. 1 is a schematic diagram of a flexible housing 11 of a pelvic floor muscle pressure detection device 100 according to an embodiment of the present application. Figure 4As shown, the flexible housing 11 is formed with a tubular portion and a spherical portion, and the spherical portion is convexly arranged on one axial side of the tubular portion. On the one hand, the spherical portion increases the contact area between the probe and the pelvic floor muscle, so that the pressure sensor array can capture more comprehensive changes in pelvic floor muscle pressure. Therefore, it is not necessary to repeatedly detect different positions of the cavity by applying external forces such as movement and rotation, reducing the complexity of the operation and the influence of external forces on the detection accuracy. On the other hand, the rounded appearance of the spherical portion makes the probe smoother during the insertion of the probe into the vagina or rectum of the object being tested, reducing the operation time of the pelvic floor muscle pressure detection and improving the detection efficiency. At the same time, it also reduces the discomfort of the patient during the detection process and improves the overall detection experience. On the third hand, the combination of the spherical portion and the tubular portion can better adapt to the internal structure of the human body, especially the anatomical structure of the female reproductive system. The probe can be more closely fitted to the internal contour of the vagina or rectum to improve the comfort and accuracy of the detection. On the fourth hand, the radial dimensions of the spherical portion and the tubular portion in this embodiment are consistent, and the consistent diameter design helps to improve the structural stability of the entire probe 1. The stress concentration and structural deformation problems caused by different diameters are avoided, and the service life of the probe 1 is extended.

[0061] In this embodiment, the pressure transmission module 12 is disposed between the flexible housing 11 and the pressure sensing module 13, and is used to transmit the pelvic floor muscle pressure to the ion-type pressure sensor array 131 of the pressure sensing module 13, so as to improve the accuracy and reliability of pelvic floor muscle pressure detection.

[0062] Figure 5 is a structural schematic diagram of a pressure transmission block 121 in a pelvic floor muscle pressure detection device 100 according to an embodiment of the present application, Figure 6 FIG. 1 is a schematic diagram of the structure of the pressure transmission block holder 122 in the pelvic floor muscle pressure detection device 100 according to an embodiment of the present application. In some embodiments, as Figure 5 and Figure 6 As shown, the pressure transmission module 12 includes a pressure transmission block 121 and a pressure transmission block holder 122. The pressure transmission block holder 122 includes an outer wall arranged inside the flexible shell 11 and having the same shape as the tubular portion and the spherical portion. A group of mounting holes are penetrated through the outer wall. The pressure transmission block 121 is penetrated through the group of mounting holes and can be movably arranged along the hole depth direction of the group of mounting holes to transmit the pelvic floor muscle pressure to the ionizing pressure sensor array 131.

[0063] It should be understood that, firstly, the pressure transmission block holder 122 provides a stable support structure for the pelvic floor muscle pressure detection device 100, ensuring the structural stability of the entire device. Secondly, the hollowed-out mounting holes on the pressure transmission block holder 122 ensure the normal operation of the pressure transmission block 121. Thirdly, the pressure transmission block holder 122 has an outer wall that is consistent with the internal shape of the flexible housing 11, which ensures that the pressure transmission block 121 is evenly stressed in all directions, avoiding the problem of excessive local pressure.

[0064] In a specific application process, when the probe 1 is inserted into the body of the object being measured, the flexible housing 11 is squeezed by the pelvic floor muscles and deformed, and this deformation will directly act on the pressure transmission block 121. The mounting hole on the pressure transmission block holder 122 provides a movable space for the pressure transmission block 121, so that the pressure transmission block 121 can move along the hole depth direction after being stressed. This movement will evenly transfer the pressure to the ion-type pressure sensor array 131, thereby achieving accurate measurement of the pelvic floor muscle pressure.

[0065] In some embodiments, Figure 6 As shown, the pressure transmission block holder 122 is provided with a groove on the side axially away from the spherical portion, and the flexible shell 11 is provided with a buckle portion protruding toward the inner side of the pressure transmission block holder 122, and the buckle portion is inserted and connected to the groove so that the flexible shell 11 maintains a snap connection when it is sleeved on the pressure transmission block holder 122. On the one hand, through the cooperation of the groove and the buckle portion, the contact area and friction between the flexible shell 11 and the pressure transmission block holder 122 are increased, making the overall structure more stable, less prone to relative movement, and the flexible shell 11 will not fall off during use. On the other hand, the close cooperation between the groove and the buckle portion helps to improve the sealing of the system and reduce the infiltration of body fluids in the vagina or intestine. On the third hand, the snap connection is simple and easy to operate, and can be easily assembled and disassembled, reducing the cost and complexity of production and maintenance.

[0066] Figure 7 1 is a schematic structural diagram of an FPC flexible flat cable fixing frame 132 in a pelvic floor muscle pressure detection device 100 according to an embodiment of the present application. Figure 8 FIG. 1 is a schematic diagram of the structure of the FPC flexible flat cable assembly 133 in the pelvic floor muscle pressure detection device 100 according to an embodiment of the present application. In this embodiment, Figure 7 and Figure 8As shown, the pressure sensing module 13 is a group of modules for detecting and measuring pressure, mainly composed of an FPC flexible flat cable fixing frame 132, an FPC flexible flat cable assembly 133, an ion-type pressure sensor array 131, etc. Its main function is to convert the detected pressure signal into a sensing capacitance signal, and transmit it to the signal processing module 21 through the FPC flexible flat cable assembly 133 for processing and analysis.

[0067] In some embodiments, the FPC flexible flat cable fixing frame 132 is fastened to the inside of the pressure conducting block holder 122. The FPC flexible flat cable assembly 133 is disposed on the outer surface of the FPC flexible flat cable fixing frame 132. The ion-type pressure sensor array 131 is arranged in the FPC flexible flat cable assembly 133 in an array form.

[0068] It should be understood that the FPC flexible flat cable fixing frame 132 is a bracket used to fix the FPC flexible flat cable assembly 133, which is usually made of plastic or metal and has a certain strength and rigidity. On the one hand, it is used to firmly fix the FPC flexible flat cable assembly 133 inside the pressure transmission block retaining frame 122 to ensure that it will not be displaced or loosened during use. On the other hand, it is to provide sufficient support force to prevent the FPC flexible flat cable assembly 133 from being deformed or damaged when under pressure. It has the beneficial effects of improving the stability of the FPC flexible flat cable assembly 133, ensuring the accurate measurement of the off-line pressure sensor array 131, simplifying the assembly process, and reducing production costs and maintenance difficulties.

[0069] Fig. 9 is based on Figure 7 The AA cross-sectional view of the FPC cable fixing frame 132 is shown in FIG. Fig.10 is based on Fig. 9 The enlarged detail of the M position of the FPC cable fixing frame 132 is shown in the figure. Fig.11 is based on Fig. 9 The schematic BB cross-sectional view of the FPC flexible flat cable fixing frame 132 is shown in FIG. Fig.12 is based on Fig.11 The enlarged detail of the FPC cable fixing frame 132 at position N is shown in FIG. Figures 9 to 12 As shown, the FPC flexible cable fixing frame 132 is composed of two parts, the cylinder on the left half and the hole on the right half, through the interference fit, the left and right halves are tightly connected and fixed to ensure that they will not be displaced or loosened during use. The hole shape refers to the inner hole structure used to achieve interference fit with the cylinder, which can be a variety of shapes, such as circular, triangular, rectangular, hexagonal, etc. Hexagonal holes are preferred because hexagonal holes have good mechanical properties, can evenly disperse stress, and avoid damage or deformation of parts caused by excessive local force.

[0070] In some embodiments, the pressure transmission block holder 122 is interference-fitted with the inner hole structure (such as a hexagonal hole) on the FPC flexible cable holder 132 through a cylinder. Since the pressure transmission block holder 122 is divided into two parts, the left pressure transmission block holder 122 can be provided with 5 fixing points, and the right pressure transmission block holder 122 can be provided with 5 fixing points. While improving the installation accuracy and stability of the pressure transmission block holder 122, the accuracy and reliability of pressure transmission are ensured.

[0071] The FPC soft flat cable assembly 133 is a flexible circuit board used to connect and control the ion-type pressure sensor array 131, and connect the ion-type pressure sensor array 131 with the signal processing module 21 to achieve signal transmission and processing. It is usually composed of a flexible substrate and a conductive line. On the one hand, efficient control and data collection of the ion-type pressure sensor array 131 are achieved. On the other hand, due to its good flexibility, it can adapt to various complex shapes and structures, thereby improving the flexibility and adaptability of the device.

[0072] The ion-type pressure sensor array 131 includes a sensing array composed of ion-type pressure sensors. The ion-type pressure sensor array 131 includes a flexible ion film dielectric layer and an electrode array layer composed of m rows and n columns of electrodes, where m and n are integers greater than or equal to 1. When the probe 1 is inserted into the object to be measured, the pelvic floor muscle pressure of the object to be measured acts on the surface of the flexible shell 11, and the ion film dielectric layer will deform, causing the capacitance between the electrodes to change, thereby converting the pelvic floor muscle pressure into a sensing capacitance signal.

[0073] In some embodiments, Figure 1 and Figure 2 As shown, the ionization pressure sensor array 131 is evenly spaced on the inner surface of the flexible housing 11 in the form of an array of m rows and n columns, and faces the inner side of the tubular portion and the spherical portion respectively. It can be understood that the evenly spaced sensor array can provide a more uniform pressure detection result and reduce the error of spatial resolution.

[0074] Fig.13 is a structural schematic diagram of an array of non-uniformly spaced ion-type pressure sensors 131 in a pelvic floor muscle pressure detection device 100 according to an embodiment of the present application, Fig.14 is a three-dimensional isometric view of an array of non-uniformly spaced ion-type pressure sensors 131 in a pelvic floor muscle pressure detection device 100 according to an embodiment of the present application. In some embodiments, as Fig.13 and Fig.14As shown, the ion-type pressure sensor array 131 is arranged in an array form of m rows and n columns at non-uniform intervals on the inner surface of the flexible shell 11, and faces the inner side of the tubular part and the spherical part respectively. Among them, the arrangement density of the ion-type pressure sensor array 131 in the first length area of ​​the tubular part close to the handle 2 is greater than the arrangement density in the second length area of ​​the tubular part away from the handle 2. It can be understood that in the actual detection of the pelvic floor muscles, more emphasis may be placed on the pressure detection accuracy of the key points of the pelvic floor muscles of the object being tested, and the non-uniformly spaced sensor array can provide higher detection accuracy in the key areas of the probe (such as the partial area close to the handle), thereby further meeting the need for high-precision detection of pelvic floor muscle pressure in different detection scenarios.

[0075] In some embodiments, the FPC flexible cable assembly 133 further includes a multi-way selection unit, which is used to time-share select each row of the ion-type pressure sensor and / or each column of the ion-type pressure sensor array 131, so that even if the number of analog-to-digital conversion (ADC) channels of the signal processing module 21 is limited, it can still ensure that the detection requirements of all ion-type pressure sensors are met. Therefore, this embodiment can not only effectively utilize limited hardware resources and avoid resource waste, but also ensure the detection accuracy and efficiency of the device. Through the flexible switching and control of the multi-way selection unit, efficient management and data collection of the ion-type pressure sensor array 131 are achieved, providing a reliable basis for subsequent data analysis and decision-making.

[0076] In this embodiment, the signal processing module 21 built into the handle 2 is a key component for realizing pelvic floor muscle pressure detection. It is electrically connected to the ion-type pressure sensor array 131 and is responsible for converting the sensing capacitance signal generated by the ion-type pressure sensor array 131 into a detection voltage signal, thereby obtaining the pelvic floor muscle pressure value of the object being measured. After converting the sensing capacitance signal from the ion-type pressure sensor array 131 into a detection voltage signal, the signal processing module 21 obtains the sensing capacitance value of the ion-type pressure sensor corresponding to the detection voltage signal based on the analog-to-digital conversion calculation of the detection voltage signal, and obtains the true pressure value of the ion-type pressure sensor based on the pressure calibration function of the ion-type pressure sensor.

[0077] Fig.15 is a schematic diagram of the structure of the handle 2 in the pelvic floor muscle pressure detection device 100 according to an embodiment of the present application, Fig.16 FIG. 1 is an exploded view of the handle 2 in the pelvic floor muscle pressure detection device 100 according to an embodiment of the present application. Fig.15 and Fig.16 As shown, the handle 2 also includes:

[0078] The housing assembly includes an upper housing assembly 221 and a lower housing assembly 222, wherein the upper housing assembly 221 and the lower housing assembly 222 form a receiving chamber 200;

[0079] A fixing nut 23, used to fasten the upper shell component 221 and the lower shell component 222;

[0080] The connecting component 24 is accommodated in the receiving cavity 200 . The connecting component 24 is provided with threads. The connecting component 24 is fastened to the fixing nut 23 through the threads.

[0081] It should be understood that the housing assembly is a shell structure composed of an upper housing assembly 221 and a lower housing assembly 222, which is used to accommodate and protect the internal signal processing module 21 and other electronic components. A special-shaped sealing ring is provided between the upper housing assembly 221 and the lower housing assembly 222 to prevent liquid from entering the handle 2.

[0082] The fixing nut 23 is a fastener used to fasten the upper shell component 221 and the lower shell component 222, and can be made of metal or plastic, with certain strength and rigidity. On the one hand, it improves the sealing and stability of the shell component, ensuring the safety and reliability of the internal components. On the other hand, it simplifies the assembly process, reduces the production cost and maintenance difficulty.

[0083] The connection assembly 24 is a structure for connecting the probe 1 and the housing assembly. It is connected to the fixing nut by threaded fastening, which ensures that it will not be displaced or loosened during use, and also strengthens the fastening connection between the upper housing assembly 221 and the lower housing assembly 222. The setting of the threaded connection, on the one hand, improves the installation accuracy and stability of the connection assembly 24, and ensures the accuracy and reliability of the measurement results. On the other hand, it simplifies the assembly process and reduces the production cost and maintenance difficulty.

[0084] In some embodiments, the connection component 24 is provided with a positioning hole at one end facing the probe 1, and a buckle is provided on the hole wall of the positioning hole. The probe 1 is inserted along the hole depth direction of the positioning hole and is clamped to the buckle, so that the probe 1 is installed in the positioning hole at a fixed angle. By inserting the probe 1 into the positioning hole of the connection component 24 and clamping it through the buckle, the probe 1 can be accurately positioned and fixed, and the assembly process is simplified, and the production cost and maintenance difficulty are reduced.

[0085] In some embodiments, a foolproof structure is provided on the connection component 24 so that the probe 1 can only be installed in the positioning hole at a fixed angle. As an optional embodiment of the foolproof structure, a concave-convex structure is used to limit the insertion angle and position of the probe 1. A groove or a protrusion can be designed on the connection component 24 to match the corresponding structure on the pressure transmission block holder 122. As another optional embodiment of the foolproof structure, a guide structure is used to guide the probe 1 to be correctly inserted and limit its range of movement. This can be achieved by designing a guide groove or a guide pin on the connection component 24.

[0086] Fig.17 is a schematic diagram of the structure of the connector assembly 212 in the pelvic floor muscle pressure detection device 100 according to an embodiment of the present application. In some embodiments, such as Fig.16 and 17 As shown, the signal processing module 21 includes:

[0087] The circuit board 211 is fixedly disposed in the storage cavity 200;

[0088] The connector component 212 includes an elastic connecting probe 2121 and a flexible flat cable vertical socket 2122. The elastic connecting probe 2121 is protruding from the side of the connector component 212 facing the connecting component 24, and the flexible flat cable vertical socket 2122 is arranged on the side of the connector component 212 facing away from the connecting component 24, and is used to electrically connect the elastic connecting probe 2121 to the circuit board 211.

[0089] It should be understood that the circuit board 211 is a signal processing unit, which is composed of a controller and a capacitance-pressure conversion circuit. The controller outputs the corresponding rectangular wave signal to the capacitance-pressure conversion circuit through the DAC port, and then uses the controller ADC port to collect the output end of the capacitance-pressure conversion circuit to obtain the pressure value. A low-power microcontroller can be selected to receive sensor data and perform calculations, and a precision op amp can be selected to ensure the accuracy of the capacitance-pressure conversion.

[0090] In some embodiments, the circuit board 211 is fixed between the upper shell component 221 and the lower shell component 222 of the handle 2 by screws to ensure that it will not be displaced or loosened during use. The connector component 212 is fixed to the connection component 24. The elastic connection probe 2121 and the flexible cable vertical socket 2122 are welded to the side of the connector component 212 facing away from the connection component 24. The handle 2 is provided with a sealing ring at each connection, and the waterproof level reaches IP6 or above.

[0091] In some embodiments, the FPC flexible flat cable assembly 133 is provided with a connection contact along the side of the FPC flexible flat cable fixing frame 132 axially away from the spherical portion, and when the probe 1 is inserted into the positioning hole, the connection contact is triggered to achieve electrical connection with the elastic connection probe 2121. At this time, the elastic connection probe 2121 will be compressed to a certain stroke to ensure that the connection contact of the FPC flexible flat cable assembly 133 is in full contact with the elastic connection probe 2121.

[0092] In some embodiments, the upper shell component 221 is provided with a probe release button component 25, and by pressing the probe release button component 25, the probe 1 is disengaged from the buckle and pops out of the positioning hole under the rebound force of the elastic connection probe 2121.

[0093] Specifically, the probe release button assembly 25 is composed of a button, a compression spring, a sealing ring, a gasket and an E-type retaining ring; it is installed on the upper shell assembly 221, and the hole on the upper shell assembly 221 through which the probe release button assembly 25 passes is beveled. The compression spring, the gasket and the sealing ring are sequentially installed on the button, and then an E-type retaining ring is installed inside the upper shell assembly 221 after passing through the corresponding hole on the upper shell assembly 221; due to the action of the compression spring, the sealing ring will be squeezed into the bevel of the corresponding hole on the upper shell assembly 221 to form a sealing structure.

[0094] When the pelvic floor muscle pressure test is completed and the probe 1 needs to be removed, the button can be pressed to squeeze the corresponding module on the pressure transmission block retaining frame 122. When the deformation reaches a certain degree, the probe 1 will be detached from the buckle in the connecting component 24. Since the elastic connecting probe 2121 is always in a compressed state, when the probe 1 is detached from the buckle, the elastic force of the elastic connecting probe 2121 will pop out the handle 2, thereby completing the removal of the probe 1.

[0095] In some embodiments, the circuit board 211 is provided with an indicator light 26, and the upper shell component 221 is provided with a light guide column and a light exit hole, and the light guide column is used to guide the light emitted by the indicator light 26 to the light exit hole and emit it to indicate the pelvic floor muscle detection status, such as preparation, detection, detection completion, etc., and can also consider the indication of abnormal status, such as equipment failure, low power, etc. A sealing ring is provided on the light guide column to prevent liquid from entering the handle from the light guide hole of the upper shell component 221.

[0096] In some embodiments, the pelvic floor muscle pressure detection device 100 further includes a USB data cable 3, which is connected and fixed to the circuit board 211 by welding or a socket, and is electrically connected to the circuit board 211 to power the circuit board 211 and support the transmission of the pelvic floor muscle pressure value of the object being tested to the electronic device. The pelvic floor muscle pressure value is transmitted to the electronic device by wired communication through the USB data cable 3, which can be unaffected by wireless signal interference, provides a more stable connection, and is not prone to interruption or packet loss during data transmission.

[0097] In some embodiments, a USB male connector is provided at one end of the USB data cable 3 and a rubber protective cover is provided at the other end. The rubber protective cover can be fixed between the upper shell component 221 and the lower shell component 222 to protect the USB data cable 3 from being damaged during use and also form a sealing structure.

The buckle part is inserted and connected to the groove, so that the flexible shell 11 can maintain a buckle connection when it is sleeved on the pressure transmission block holder, thereby improving the stability and reliability of the device.

[0101] The pressure sensing module 13 includes an FPC flexible cable fixing frame 132 and an FPC flexible cable assembly 133, which can convert the sensing capacitance signal of the ion-type pressure sensor array 131 into a detection voltage signal, and time-share select each row of ion-type pressure sensors and / or each column of ion-type pressure sensors in the ion-type pressure sensor array through a multi-way selection unit to improve the detection efficiency.
