Description

Technical Field

[0001] The present disclosure relates to ultrasound equipment technology, and more particularly, to a portable tissue elasticity detection device. Background Art

[0002] Currently, tissue elasticity testing devices have developed to the point where they can be used by most users to measure their own tissue elasticity. These devices generate low-frequency vibrations through a probe to stimulate the mechanical response of the tissue. Using technologies such as ultrasound or magnetic resonance imaging, they track the propagation of shear waves to calculate the tissue's elasticity. The widespread availability of these devices has made tissue elasticity testing technology more accessible to the average user, facilitating early health monitoring and disease prevention.

[0003] However, tissue elasticity testing devices are not highly integrated and are relatively large. Furthermore, due to the lack of professional knowledge about tissue elasticity testing, ordinary users often make mistakes when operating the devices, resulting in inaccurate tissue status measurements and a negative user experience. For example, during tissue elasticity testing, the pressure applied by the probe to the tissue under test may be too high or too low, affecting the accuracy of the tissue state. Furthermore, excessive pressure can cause discomfort to the user, impacting the user experience. Summary of the Invention

[0045] Various exemplary embodiments of the present specification will now be described in detail with reference to the accompanying drawings.

[0046] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the embodiments of this specification, its application, or uses.

[0047] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0048] <First embodiment>

[0049] Figure 1A portable tissue elasticity detection device according to a first embodiment is shown. The portable tissue elasticity detection device is a handheld device, which is convenient for users to operate, use and carry.

[0050] according to Figure 1 As shown, the portable tissue elasticity detection device 100 includes a processor 101, a control device 102, an ultrasonic transceiver circuit 103, a motor drive circuit 104, a motor 105, and a power supply arranged in a shell, as well as an ultrasonic transducer 106 and a pressure sensor 107 arranged on a probe located at one end of the shell.

[0051] according to Figure 1 As shown, the control device 102 is connected to the processor 101, the ultrasonic transceiver circuit 103, the motor drive circuit 104 and the pressure sensor 107. The motor drive circuit 104 is connected to the motor 105. The ultrasonic transducer 106 is connected to the ultrasonic transceiver circuit 103 and the motor 105.

[0052] power supply( Figure 1 The power supply (not shown) is respectively connected to the processor 101, the control device 102, the ultrasonic transceiver circuit 103, the motor drive circuit 104, the motor 105, the ultrasonic transducer 106, and the pressure sensor 107. The power supply is used to power the processor 101, the control device 102, the ultrasonic transceiver circuit 103, the motor drive circuit 104, the motor 105, the ultrasonic transducer 106, and the pressure sensor 107.

[0053] The pressure sensor 107 is used to collect the pressure applied by the probe to the tissue to be measured, and send the collected pressure value to the control device 102. The tissue to be measured can be any organ tissue, such as the liver, kidney or spleen.

[0054] The control device 102 is used to control the ultrasonic transceiver circuit to transmit ultrasonic waves in the frequency range of 20kHz to 100MHz, control the motor drive circuit to drive the motor to vibrate, so as to generate low-frequency shear waves in the frequency range of 0.5Hz to 3000Hz through the ultrasonic transducer, and collect at least 10 frames of ultrasonic echo signals, when it is determined that the pressure value meets the preset requirements, wherein the pulse repetition frequency of the echo signal is within the frequency range of 10Hz-40000Hz.

[0055] The control device 102 is further configured to obtain measurement data collected by the ultrasonic transceiver circuit 103 and send the measurement data to the processor 101 .

[0056] The processor 101 is configured to determine the state of the tissue to be measured based on the measurement data.

[0057] according to Figure 2As shown, the ultrasonic transceiver circuit 103 includes an ultrasonic transmitter 103a and an ultrasonic receiver 103b.

[0058] according to Figure 2 As shown, the control device 102 includes a motor control unit 102a and an ultrasonic transceiver control unit 102b. The motor control unit 102a is used to control the motor drive circuit 104 to drive the motor 105 to vibrate. The ultrasonic transceiver control unit 102b is used to control the ultrasonic transmitter 103a to transmit ultrasonic waves, obtain ultrasonic signals received by the ultrasonic receiver 103b, and obtain measurement data based on the received ultrasonic signals.

[0059] The power supply includes a battery and a power manager. The battery is connected to the power manager. The power manager is also connected to a control device. The control device is configured to output a control signal to the power manager, causing it to adjust the battery's output voltage.

[0060] In the prior art, the power manager is installed on the control device, which complicates the control device's circuit design and occupies a large space. In this embodiment, the battery is integrated with the power manager. This eliminates the need for the power manager on the control device, reducing the complexity of the control device's circuit design and facilitating heat dissipation.

[0061] In some embodiments, the control device generates a square wave excitation signal to control the motor drive circuit to drive the motor to vibrate. The high energy requirements of the motor drive circuit complicate the circuit design of the control device. However, the square wave excitation signal can be directly generated using a simple logic circuit or timer. This reduces the complexity of the circuit design and the number and variety of components required, thereby lowering the circuit's manufacturing cost and maintenance. Furthermore, the use of square wave excitation effectively reduces the weight of the probe. Existing sinusoidal wave excitation circuits often require heavy digital-to-analog conversion circuits, operational amplifier circuits, and bulky high-voltage, high-current power amplifier circuits to achieve a stable sinusoidal output. Square wave excitation circuits, on the other hand, eliminate these bulky components, significantly reducing the weight of the probe and making it easier to operate while holding. Furthermore, the use of square wave excitation reduces power supply requirements. A single power supply can power the square wave excitation circuit, whereas a sinusoidal wave excitation circuit may require more complex power management circuitry or a higher voltage level. Using a single power supply not only simplifies the power supply design but also improves the device's portability and battery life. The control device may send a square wave excitation signal to control the ultrasonic transceiver circuit, or may send other excitation signals, for example, a sine wave excitation signal to control the ultrasonic transceiver circuit.

[0062] <Second embodiment>

[0063] Portable tissue elasticity detection equipment needs to be used for a long time outdoors or indoors without power. In order to improve the endurance of the equipment, the present disclosure proposes a solution to save the power consumption of the equipment by cooperating with a posture sensor and a pressure sensor.

[0064] In some embodiments, the probe is provided with a posture sensor configured to transmit collected probe posture data to a control device. The control device is configured to, upon determining that the probe posture data has not changed within a preset time period, or upon determining that the pressure value has not changed within a preset time period, control the operating state of the device to be adjusted to a dormant state or a standby state outside of a set data collection period.

[0065] In this embodiment, the posture sensor can periodically collect the posture data of the probe and send it to the control device. The posture sensor can be a gyroscope, etc., which is not limited here.

[0066] The pressure sensor can periodically collect pressure values and send the pressure values to the control device.

[0067] When the control device determines that the probe posture data changes within the preset time period and / or the pressure value changes within the preset time period, it indicates that the device is in use. At this time, the control device controls the ultrasonic transceiver circuit to transmit ultrasonic waves.

[0068] When the control device determines that the probe posture data has not changed within a preset time period, or when it determines that the pressure value has not changed within a preset time period, it indicates that the device may be in an unused state, and the operating state of the control device is adjusted to a dormant state or a standby state outside the set data collection time period to save power consumption of the device.

[0069] <Third embodiment>

[0070] In some embodiments, the portable tissue elasticity detection device establishes a communication connection with a host computer.

[0071] In this embodiment, when the host computer is in communication with the device, the device can transmit the status of the tissue under test to the host computer for display, or the device can transmit measurement data to the host computer for use in determining the status of the tissue under test. The host computer can control the device's on and off, as well as set the device's ultrasound control parameters, vibration control parameters, etc., which are not limited here.

[0072] The control device is used to control the operating state of the device to be adjusted to a dormant state or a standby state when it is determined that the heartbeat communication between the device and the host computer is abnormal.

[0073] When it is determined that the heartbeat communication between the device and the host computer is abnormal, there is a problem of disconnection between the device and the host computer. In this case, the control device adjusts the operating state of the device to a dormant state or a standby state to save power consumption of the device.

[0074] In addition, the control device can also be used to control the running state of the device to be adjusted to the working state when it is determined that the heartbeat communication between the device and the host computer is normal.

[0075] In order to further reduce the power consumption of the device, in some embodiments, the control device is also used to control the device to shut down when the duration of the abnormal heartbeat communication between the device and the host computer is greater than or equal to the set duration.

[0076] according to Figure 3 As shown, the device energy-saving scheme executed by the control device is described in detail below through an example, which specifically includes steps S301 to S308.

[0077] Step S301, determine whether there is an abnormality in the heartbeat communication between the device and the host computer; if so, execute step S302, if not, execute step S305.

[0078] Step S302: The operating state of the control device is adjusted to a dormant state or a standby state. Next, step S303 is executed to determine whether the duration of the abnormal heartbeat communication between the device and the host computer is greater than or equal to the set duration; if so, step S304 is executed; if not, the process returns to step S302.

[0079] Step S304: control the device to shut down.

[0080] Step S305 , determining whether the probe posture data has changed within a preset time period; if not, executing step S307 ; if so, executing step S306 .

[0081] Step S306, determining whether the pressure value changes within the preset time period; if so, executing step S308, if not, executing step S307.

[0082] Step S307 : The operating state of the control device is adjusted to a dormant state or a standby state outside the set data collection time period.

[0083] Step S308: Control the ultrasonic transceiver circuit to transmit ultrasonic waves.

[0084] <Fourth embodiment>

[0085] Since the probe is not aligned with the tissue to be tested and the pressure applied by the probe to the tissue to be tested is inappropriate (i.e., the pressure is too high or too low), it will seriously affect the accuracy of the state of the tissue to be tested detected by the portable tissue elasticity detection device. Therefore, in order to avoid the abnormal state of the tissue to be tested due to improper tissue elasticity detection operation of the user, and to improve the universality of the portable tissue elasticity detection device for users with different professional depths.

[0086] This embodiment proposes a pre-judgment solution for tissue elasticity detection to improve the accuracy of the state of the tissue to be tested obtained by users with different professional depths through the portable tissue elasticity detection device.

[0087] Based on this, Figure 4 As shown, the control device is used to control the ultrasonic transceiver circuit to transmit ultrasonic waves in the frequency range of 20kHz to 100MHz, and control the motor drive circuit to drive the motor to vibrate, so as to generate low-frequency shear waves in the frequency range of 0.5Hz to 3000Hz through the ultrasonic transducer when it is determined that the pressure value meets the preset requirements, including: steps S401 to S403.

[0088] Step S401 : When it is determined that the pressure value is greater than a first preset pressure threshold, the ultrasonic transceiver circuit is controlled to transmit ultrasonic waves in a frequency range of 20 kHz to 100 MHz and receive echo signals of the ultrasonic waves.

[0089] In this embodiment, after the portable tissue elasticity detection device is started, first, when a pressure greater than a first preset pressure threshold is applied to the user, the ultrasonic transceiver circuit is controlled to transmit ultrasonic waves in the frequency range of 20kHz to 100MHz and receive the echo signal of the ultrasonic waves.

[0090] Step S402: determining whether the probe is aligned with the tissue to be measured based on the measurement data.

[0091] In this embodiment, the control device obtains at least 10 frames of ultrasonic echo signals received by the ultrasonic transceiver circuit and analyzes the at least 10 frames of ultrasonic echo signals to obtain measurement data. The measurement data includes ultrasonic image data. The ultrasonic image data can be used to characterize the tissue currently aligned with the probe. The processor determines whether the probe is aligned with the tissue to be measured based on the ultrasonic image data.

[0092] If the probe is not aligned with the tissue to be tested, the process returns to step S402.

[0093] In step S403, when it is determined that the pressure value is greater than a second preset pressure threshold and when it is determined that the probe is aligned with the tissue to be measured, the motor driving circuit is controlled to drive the motor to vibrate, so as to generate a low-frequency shear wave in the frequency range of 0.5 Hz to 3000 Hz through the ultrasonic transducer.

[0094] In this embodiment, the second preset pressure threshold may be a pressure value range corresponding to the state of the tissue to be tested that is accurately determined based on historical tissue elasticity testing.

[0095] The first preset pressure threshold corresponds to a pressure value range when the detection probe is aligned with the tissue to be tested, which is smaller than the second preset pressure threshold during tissue elasticity testing.

[0096] When it is determined that the probe is aligned with the tissue to be measured, a pressure value is reacquired. When it is determined that the reacquired pressure value is greater than a second preset pressure threshold, the motor drive circuit is controlled to drive the motor to vibrate, thereby generating a low-frequency shear wave in a frequency range of 0.5 Hz to 3000 Hz through the ultrasonic transducer. If the reacquired pressure value is less than or equal to the second preset pressure threshold, pressure values are continuously acquired until the reacquired pressure value exceeds the second preset pressure threshold.

[0097] To improve user comfort during tissue elasticity testing, the pressure value during tissue elasticity testing must not only be greater than the second preset pressure threshold but also be less than a third preset pressure threshold, where the third preset pressure threshold is the maximum pressure value that satisfies the user's comfort experience.

[0098] Because the pressure required to detect alignment with the tissue under test is lower than that required for tissue elasticity testing, the user is prompted to adjust the pressure applied to the skin. The Tissue Position Prompt Area displays the position detection results, providing a convenient reminder to the user that the probe is aligned with the tissue under test. Once the user is prompted that the probe is aligned with the tissue under test, they can increase the pressure applied to the skin surface, thereby facilitating the user's operation to meet the pressure requirements for tissue elasticity testing and improving user convenience.

[0099] In this embodiment, when the probe is aimed at the tissue to be tested and the pressure value is greater than the second pressure threshold, it means that the probe has met the requirements for tissue elasticity detection. At this time, the motor drive circuit is controlled to drive the motor to vibrate, so as to generate low-frequency shear waves in the frequency range of 0.5Hz to 3000Hz through the ultrasonic transducer, thereby regaining measurement data for tissue elasticity detection.

[0100] By setting different pressure thresholds for detecting probe alignment and tissue elasticity, user operation accuracy can be improved and user errors can be reduced. Furthermore, by setting the first pressure threshold lower than the second pressure threshold, energy consumption during the probe alignment test can be reduced.

[0101] In combination with the second embodiment, the control device is further configured to determine the ultrasonic control parameters of the ultrasonic transceiver circuit and the vibration control parameters of the motor drive circuit according to the tissue type of the tissue to be tested and the detection object information, including: step S501 and step S502.

[0102] In step S501 , the control device is configured to determine a first ultrasonic control parameter of the ultrasonic transceiver circuit according to the tissue type of the tissue to be tested and the test object information when it is determined that the pressure value is greater than a first preset pressure threshold.

[0103] In this embodiment, the first ultrasonic control parameter includes at least one of a first ultrasonic frequency and a first ultrasonic amplitude.

[0104] In step S502, the control device is used to determine the second ultrasonic control parameter of the ultrasonic transceiver circuit and the vibration control parameter of the motor drive circuit according to the tissue type of the tissue to be tested and the detection object information when it is determined that the pressure value is greater than the second preset pressure threshold.

[0105] In this embodiment, the second ultrasonic control parameter includes at least one of a second ultrasonic frequency and a second ultrasonic amplitude.

[0106] The first preset pressure threshold is smaller than the second preset pressure threshold, the first ultrasonic frequency is larger than the second ultrasonic frequency, and the first ultrasonic amplitude is larger than the second ultrasonic amplitude.

[0107] Steps S501 and S502 above indicate that when performing a tissue elasticity test on a subject's tissue, the probe is first aligned with the tissue, and then the tissue elasticity test is performed. In addition to different pressure thresholds, these two stages also utilize different ultrasound control parameters. Specifically, the probe alignment test uses the first ultrasound control parameter, while the tissue elasticity test uses the second ultrasound control parameter.

[0108] Since the morphology, boundaries and internal structure of the organ that the current probe is aimed at need to be clearly displayed when detecting whether the probe is aimed at the tissue to be tested, a higher penetration depth and resolution are required. Therefore, the first ultrasonic frequency and first ultrasonic amplitude corresponding to the detection of whether the probe is aimed at the tissue to be tested are higher.

[0109] During the tissue elasticity testing phase, however, no anatomical image formation is required. Therefore, the second ultrasonic frequency and amplitude can be lower—that is, the second ultrasonic frequency is lower than the first ultrasonic frequency, and the second ultrasonic amplitude is lower than the first ultrasonic amplitude. In this case, lower ultrasonic frequencies and amplitudes during tissue elasticity testing can reduce user discomfort and facilitate multiple tissue elasticity tests during this phase. Furthermore, lower ultrasonic frequencies and amplitudes during tissue elasticity testing can reduce device energy consumption, achieving energy savings.

[0110] <Fifth embodiment>

[0111] In some embodiments, according to Figure 5 As shown, the portable tissue elasticity detection device 100 further includes a display device 110, which is connected to the control device 102. The display device is provided on a housing of the portable tissue elasticity detection device.

[0112] The display device includes a pressure indication area, a signal quality indication area and a detection result quality indication area.

[0113] The display device may be an LED board connected to the control device, and the LED board includes a pressure indication area, a signal quality indication area, and a detection result quality indication area.

[0114] The control device is used to determine the pressure level information corresponding to the pressure value based on the obtained pressure value, and send the pressure level information to the display device, which is used to display the pressure level information in the pressure indication area.

[0115] In this embodiment, the control device pre-stores pressure value ranges corresponding to different pressure levels, for example, the pressure value range corresponding to the low pressure level, the pressure value range corresponding to the medium pressure level, and the pressure value corresponding to the high pressure level, so as to determine the corresponding pressure level information based on the obtained pressure value.

[0116] For example, the low pressure level is 0-10 kPa, the medium pressure level is 10-50 kPa, and the high pressure level is 50-100 kPa. If the current pressure value is 9 kPa, the pressure level information is determined to be a low pressure level.

[0117] The pressure indication area may display different pressure levels through first set colors of different color depths, or may display different pressure levels through different patterns, texts, etc., which is not limited here.

[0118] In one example, the first set color can be green. Green can be divided into light green, medium green, and dark green according to the color depth. Different depths of green indicate different pressure levels. Light green corresponds to low pressure levels, medium green corresponds to medium pressure levels, and dark green corresponds to high pressure levels. This allows users to quickly understand the current pressure status and adjust device operations accordingly.

[0119] The control device is used to determine signal quality level information based on the measurement data and send the signal quality level information to the display device, and the display device is used to display the signal quality level information in the signal quality indication area.

[0120] In this embodiment, the measurement data includes ultrasonic image data, and the control device determines signal quality level information based on the ultrasonic image data. The control device's quality assessment of the ultrasonic image data is primarily divided into two aspects: first, evaluating whether the ultrasonic image data is an ultrasonic image of the tissue to be measured, and second, evaluating whether the ultrasonic image data contains interference data caused by, for example, the subject's breathing / motion. If the ultrasonic image data is an ultrasonic image of the tissue to be measured and does not contain interference data caused by, for example, the subject's breathing / motion, the signal quality level is good. If the ultrasonic image data is not an ultrasonic image of the tissue to be measured and does contain interference data caused by, for example, the subject's breathing / motion, the signal quality level is poor.

[0121] The signal quality indicator area may display different signal quality levels through second set colors of different color depths, or may display different signal quality levels through different prompting methods such as patterns and texts, which are not limited here.

[0122] In one example, the second set color can be blue. Blue can be categorized by color depth as light blue, medium blue, and dark blue. Different shades of blue indicate different signal quality levels. Light blue corresponds to poor signal quality, medium blue corresponds to fair signal quality, and dark blue corresponds to good signal quality. This allows users to quickly understand the current signal quality status and adjust device operations accordingly.

[0123] The control device is further configured to determine confidence information of the state of the tissue to be tested, and send the confidence information of the state of the tissue to be tested to the display device, and the display device is further configured to display the confidence information in the detection result quality indication area.

[0124] In this embodiment, the confidence information of the state of the tissue to be tested can be divided into low confidence, average confidence, high confidence, etc.

[0125] The test result quality indicator area can display different confidence levels through the third set color of different color depths, or can display different confidence levels through different prompts such as different patterns and texts, which is not limited here.

[0126] In one example, the third set color is red. Red is divided into light red, medium red, and dark red according to its color depth. Different shades of red indicate different confidence levels. Light red corresponds to a fair confidence level, indicating that the status of the tissue under test is questionable or requires further examination. Medium red corresponds to a high confidence level, while dark red corresponds to a low confidence level, indicating that the status of the tissue under test is abnormal or there are serious problems. This allows users to quickly understand the confidence level of the tissue under test and take appropriate measures accordingly.

[0127] In some examples, to achieve more precise indications and provide customized setting options, a display device provided on the housing of the device can display the status of the tissue to be tested and user operation information. The display device is provided with a human-computer interaction interface, which is provided with multiple controls for user operation. The user can use the display device to adjust parameters such as the signal gain and focus of the B-ultrasound and control functions such as the start, stop, and mode switching of the elasticity test (E-ultrasound). At the same time, the display device can also display ultrasound image data, pressure indication, signal quality indication, and tissue status confidence indication in real time, so that the user can clearly and intuitively understand the process and results of tissue elasticity testing.

[0128] By providing a display device, the usability of the portable tissue elasticity testing device can be further improved, enhancing the user's operating experience. Users can intuitively and accurately obtain a variety of signal status information (pressure value, signal quality, and confidence level of the state of the tissue being tested), thereby performing elasticity testing operations more efficiently and accurately.

[0129] In conjunction with the fourth embodiment, the display device includes a detection tissue position indication area. The detection tissue position indication area can use different colors to indicate the position where the probe is aligned with the detection tissue and the position where the probe is not aligned with the detection tissue, and can also use different text, patterns, etc. to display the position detection result information, which is not limited here.

[0130] In one example, the yellow color may indicate that the probe is aligned with the tissue to be measured, and the purple color may indicate that the probe is not aligned with the tissue to be measured.

[0131] <Sixth embodiment>

[0132] Different from the first embodiment, the portable tissue elasticity detection device provided in this embodiment further includes a communication device connected to the control device.

[0133] according to Figure 6 As shown, the communication device includes a USB communication device 111 a and a WIFI communication device 111 b , and the control device 102 is connected to the USB communication device 111 a and the WIFI communication device 111 b respectively.

[0134] The portable tissue elasticity testing device can establish a communication connection with a host computer via a USB or Wi-Fi communication device. The portable tissue elasticity testing device is used to transmit measurement data to the host computer, which then determines the state of the tissue being tested based on the measurement data. The state of the tissue being tested can be displayed on the host computer, or the host computer can transmit the state of the tissue being tested to the portable tissue elasticity testing device for display on the portable tissue elasticity testing device's display device. The host computer can be a PC, tablet, or mobile phone.

[0135] When the portable tissue elasticity testing device first establishes a communication connection with a host computer via a Wi-Fi communication device, it must select a specific Wi-Fi connection and verify the connection using a key. Once verification is successful, the device can then establish a communication connection with the host computer via the Wi-Fi communication device. The Wi-Fi designation and key entry require user input. The portable tissue elasticity testing device records the specified Wi-Fi and corresponding key, allowing it to automatically establish a Wi-Fi communication connection with the host computer at a later time, eliminating the need for the user to manually connect each time. This greatly simplifies the operation process and improves the user experience.

[0136] In this embodiment, the priority of the portable tissue elasticity detection device in establishing a communication connection with the host computer via the USB communication device is higher than that of establishing a communication connection with the host computer via the WIFI communication device.

[0137] The control device is used to detect whether the device has established a communication connection with the host computer through the USB communication device. When the device has established a communication connection with the host computer through the USB communication device, the control device detects the connection status of the USB communication device and the host computer. When the connection status is disconnected, the control device controls the WIFI communication device to establish a communication connection with the host computer.

[0138] The control device is also used to detect the connection status of the device with the host computer through the USB communication device when the device has established a connection with the host computer through the WIFI communication device, and automatically disconnect the communication connection established with the host computer through the WIFI communication device when it is detected that the device has established a communication connection with the host computer through the USB communication device.

[0139] Figure 7 The following is a schematic diagram showing the specific process of establishing a communication connection between the portable tissue elasticity detection device and the host computer. Figure 7 As shown, the specific flow chart includes steps S701 to S704.

[0140] In step S701, the control device detects whether the device has established a communication connection with the host computer via the USB communication device.

[0141] If the result of executing step S701 is yes, step S702 is executed, and the control device detects the connection status between the USB communication device and the host computer.

[0142] Step S703: When the connection state is disconnected, control the WIFI communication device to establish a communication connection with the host computer.

[0143] If the result of executing step S701 is no, step S703 is executed.

[0144] In step S704 , the control device detects the connection status between the USB communication device and the host computer, and automatically disconnects the communication connection established with the host computer via the WIFI communication device when the connection status is connected.

[0145] In some embodiments, the control device is also used to control the WIFI communication device to initiate a hotspot scan when the connection state is disconnected, obtain a scan result, and establish a communication connection with the preset hotspot when the scan result is that a preset hotspot is scanned and obtained, wherein the preset hotspot is turned on by the host computer, and, when the scan result is that the preset hotspot is not scanned and obtained, control the WIFI communication device to turn on the hotspot, so that the host computer initiates a communication connection establishment request after detecting the hotspot turned on by the device, so that the host computer and the device establish a communication connection.

[0146] When the control device detects that the device has not established a communication connection with the host computer through the USB communication device, Figure 8 The specific process diagram of establishing communication connection between portable tissue elasticity detection device and host computer through WIFI module is shown. Figure 8 As shown, the specific flow chart includes steps S801 to S805.

[0147] Step S801: The control device controls the WIFI communication device to initiate a hotspot scan to determine whether a preset hotspot is found. The preset hotspot is enabled by the host computer.

[0148] If the result of executing step S801 is yes, step S802 is executed to establish a communication connection with the preset hotspot.

[0149] If the result of step S801 is no, step S803 is executed to control the WIFI communication device to turn on the hotspot.

[0150] Step S804: Detect whether the host computer sends a request to establish a connection with the hotspot opened by the WIFI communication device.

[0151] If the result of executing step S804 is yes, step S805 is executed to establish a communication connection with the host computer through the hotspot opened by the WIFI communication device.

[0152] If the result of executing step S804 is no, continue executing step S804.

[0153] Figure 9 A schematic diagram showing a communication method between a portable tissue elasticity detection device and a host computer according to an embodiment of the present invention is shown.

[0154] according to Figure 9As shown, the portable tissue elasticity detection device can establish a communication connection with the host computer through a USB communication device, and can also establish a communication connection with the host computer through a WIFI communication device.

[0155] When the portable tissue elasticity testing device's Wi-Fi communication device operates in STA (Station) mode, it initiates a hotspot scan to determine whether a preset hotspot has been found. The preset hotspot is activated by the host computer. If the preset hotspot has been found, a communication connection is established with the preset hotspot. When the portable tissue elasticity testing device's Wi-Fi communication device operates in AP (Access Point) mode, it activates its own hotspot and waits for the host computer to establish a connection via the hotspot activated by the Wi-Fi communication device.

[0156] In an embodiment of the present invention, the portable tissue elasticity detection device supports both USB and WIFI communication modes, allowing users to flexibly choose a wired or wireless connection method based on actual usage scenarios and needs, greatly improving the device's flexibility and adaptability. Furthermore, the portable tissue elasticity detection device also takes into account the priority of the communication mode, with USB mode connection taking precedence over WIFI mode. During the USB mode connection process, the device continuously monitors the connection status and immediately switches to WIFI connection mode upon detecting a disconnection, ensuring a stable connection and continuous data transmission under various circumstances.
