For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] In the existing ultrasonic therapeutic apparatus, a power supply outputs a power signal to a therapeutic head to provide electric energy for the therapeutic head. In the process of use, the power supply may have abnormal conditions such as wear and tear or failure. When the power supply has abnormal conditions, the power signal output by the power supply will have a large fluctuation, such as too large or too small, which affects the safety of the therapeutic head. Therefore, the utility model provides a power control module of a therapeutic apparatus, which can ensure the safety of the therapeutic head when the power supply has abnormal conditions, such as Figure 1 as shown in the following:

[0043] In the utility model, the power control module of the therapeutic apparatus is used for controlling the power transmitted to the therapeutic head of the therapeutic apparatus. The power control module comprises a power supply 101, a power parameter monitoring circuit 102, a main control unit 103 and an adjustment control unit 104. The power supply 101 is used for outputting a power signal to the therapeutic head. The power parameter monitoring circuit 102 is connected with the power supply 101 and is used for monitoring the power parameter of the power supply 101. The power parameter can be a power voltage or a power current, which is not limited here. Correspondingly, the power parameter monitoring circuit 102 can be a voltage monitoring circuit or a current monitoring circuit, which is not limited here.

[0044] The main control unit 103 can be an MPU (microprocessor) or an MCU (microcontroller), which is not limited here. The main control unit 103 is connected with the power parameter monitoring circuit 102 and is used for receiving the power parameter of the power supply transmitted by the power parameter monitoring circuit 102 to determine whether the power parameter of the power supply is in a preset safety range, i.e. to verify the validity of the power parameter of the power supply. The preset safety range is a parameter range in which the therapeutic head can work normally, which can be a safety voltage range or a safety current range, which is not limited here. The main control unit 103 can obtain the information of the preset safety range transmitted by a server through the server in communication connection with the power control module. It can be understood that when the power parameter of the power supply is in the preset safety range, it is determined that the power supply is in a normal condition, i.e. the validity verification of the power parameter of the power supply is passed. When the power parameter of the power supply is not in the preset safety range, it is determined that the power supply is in an abnormal condition, i.e. the validity verification of the power parameter of the power supply is not passed.

[0045] The main control unit 103 is connected with the power supply 101 through the adjustment control unit 104, and the main control unit 103 is used for driving the adjustment control unit 104 to control the power supply 101 to stop outputting power when it is determined that the power supply parameter of the power supply 101 is not in the preset safety range. That is, when the power supply 101 is in an abnormal condition, the power supply 101 is turned off by driving the adjustment control unit 104. The adjustment control unit 104 can adjust the power supply voltage or the power supply current of the power supply 101 to adjust the output power of the power supply 101, for example, by adjusting the power supply voltage or the power supply current of the power supply 101 to zero to make the power supply 101 stop outputting power.

[0046] It can be seen that, in the power control module of the therapeutic instrument, the power supply parameter monitoring circuit is used for monitoring the power supply parameter of the power supply, and the main control unit is used for determining that the power supply is in an abnormal condition when the power supply parameter is not in the preset safety range, and the adjustment control unit is driven to control the power supply to stop outputting power. Therefore, the power supply can be controlled to stop outputting power when the power supply is in an abnormal condition, so as to avoid the power signal output by the power supply affecting the safety of the treatment head and ensure the safety of the treatment head.

[0047] Further, the power supply parameter monitoring circuit comprises a voltage monitoring circuit, for example, Figure 2 As shown in the figure, the voltage monitoring circuit comprises a voltage extraction unit 1021, an analog signal sampling unit 1022, a communication isolation unit 1023 and a main control chip 1024.

[0048] The input end of the voltage extraction unit 1021 is connected with the power supply, the output end of the voltage extraction unit 1021 is connected with the input end of the analog signal sampling unit 1022, and the voltage extraction unit 1021 is used for extracting the analog voltage signal of the power supply and transmitting the analog voltage signal to the analog signal sampling unit 1022. The output end of the analog signal sampling unit 1022 is connected with the input end of the communication isolation unit 1023, and the analog signal sampling unit 1022 is used for converting the analog voltage signal into a digital voltage signal and transmitting the digital voltage signal to the communication isolation unit 1023. That is, the analog signal sampling unit 1022 can be an AD sampling chip, which can sample the analog voltage signal and convert the analog voltage signal into a digital voltage signal.

[0049] The output end of the communication isolation unit 1023 is connected with the master control chip 1024. The communication isolation unit 1023 can be an isolation transformer or an optical coupling chip, which is not limited here. The communication isolation unit 1023 is used to convert the digital voltage signal into a low-voltage digital signal, and the master control chip 1024 is used to determine the power supply voltage of the power supply based on the low-voltage digital signal. It can be understood that the power supply voltage of the power supply is generally high voltage, and the digital voltage signal sampled by the analog signal sampling unit 1022 is a high-voltage digital signal. At this time, the high-voltage digital signal can be converted into a low-voltage digital signal by the communication isolation unit 1023, such as converting a high-voltage digital signal of 80V into a low-voltage digital signal of 3.3V; the influence of the high-voltage digital signal on the master control chip 1024 can be effectively avoided, the master control chip 1024 is protected, and the stability of the voltage monitoring circuit is improved.

[0050] Further, the voltage monitoring circuit will be described in detail below, as shown in the following figure: Figure 3 The voltage extraction unit 1021 includes a first resistor R301, a second resistor R302, a third resistor R303, a fourth resistor R304, and an operational amplifier U301. One end of the first resistor R301 is connected with the positive pole +PV of the power supply, and the other end of the first resistor R301 is connected with one end of the second resistor R302 and the non-inverting input end of the operational amplifier U301. The other end of the second resistor R302 is connected with the negative pole -PV of the power supply and grounded. The inverting input end of the operational amplifier U301 is connected with one end of the third resistor R303, and the other end of the third resistor R303 is connected with the output end of the operational amplifier U301 and one end of the fourth resistor R304. The other end of the fourth resistor R304 is connected with the input end of the analog signal sampling unit.

[0051] The analog sampling unit is an AD sampling chip U302, the communication isolation unit is an optical coupling chip U303, the master control chip is an MPU microprocessor U304, AIN is an analog input pin, SCL is a clock pin, and SDA is a data transmission pin.

[0052] Further, the voltage extraction unit 1021 further includes a first capacitor C301 and a second capacitor C302. The first capacitor C301 is connected in parallel across the second resistor R302, and the first capacitor C301 is used to filter the analog voltage signal of the power supply. One end of the second capacitor C302 is connected to the other end of the fourth resistor R304, and the other end of the second capacitor C302 is grounded. The second capacitor C302 is used to filter the extracted analog voltage signal.

[0053] Further, the voltage monitoring circuit further comprises: a first pull-up resistor and a second pull-up resistor; the first pull-up resistor is arranged on the connecting line between the analog signal sampling unit and the communication isolation unit; and the second pull-up resistor is arranged on the connecting line between the communication isolation unit and the master control chip.

[0054] Further, the master control unit 103 is connected with the master control chip of the voltage monitoring circuit 102, and the master control unit is further used for determining the power supply current or the power supply power of the power supply 101 based on the power supply voltage information and the power supply internal resistance information of the power supply 101 transmitted by the master control chip of the voltage monitoring circuit 102. That is, in the master control unit 103, the power supply current of the power supply can be obtained by dividing the power supply voltage of the power supply by the power supply internal resistance of the power supply; and the power supply power of the power supply can be obtained by multiplying the power supply voltage of the power supply by the power supply current of the power supply.

[0055] It can be understood that, in the utility model, the power supply 101 is a direct current power supply, that is, outputs a direct current power signal. The master control unit 103 is further used for driving the adjustment control unit based on the power supply parameter of the power supply to control the power supply 101 to output the direct current power signal when it is determined that the power supply parameter of the power supply 101 is in a preset safe range. That is, the master control unit 103 controls the direct current power signal output by the power supply 101 in a closed loop, and the output power of the power supply 101 can be obtained based on the power supply parameter of the power supply 101; if the output power of the power supply 101 is too high, the output power of the power supply 101 is reduced through the adjustment control unit 104; and if the output power of the power supply 101 is too low, the output power of the power supply 101 is increased through the adjustment control unit 104.

[0056] Further, as shown in FIG. 1, Figure 4As shown, in the utility model, the therapeutic instrument not only includes the power control module 100, but also includes: handle control module 200, treatment head 300 and display control module. Among them, the treatment head 300 is used to provide ultrasonic transducer, realizes the energy conversion (i.e. electroacoustic energy conversion) of electric energy to ultrasonic wave;The handle control module 200 is arranged in the handle of bearing treatment head 300, and is used to provide the communication control and treatment control of treatment head, i.e. control the energy conversion and ultrasonic emission of treatment head 300;Display module 400 provides human-computer interaction display interface;Power control module 100 and display control module 400 and handle control module 200 intercommunication.

[0057] Among them, the power control module 100 further includes: drive control unit 105 and power supply drive unit 106;Drive control unit 105 is connected with main control unit 103 and power supply drive unit 106 respectively, and main control unit 103 is further used to control drive control unit 105 to output drive signal with frequency to power supply drive unit 106;That is, main control unit 103 can transmit frequency information to drive control unit 105, and drive control unit 105 outputs corresponding drive signal with frequency based on frequency information, such as outputting 2MHZ drive signal.Power supply drive unit 106 is connected with power supply 101, and power supply drive unit 106 is used to integrate direct current power signal output by power supply 101 and drive signal with frequency into power signal with frequency, and output to treatment head;Such as integrating 80V direct current power signal and 2MHZ drive signal into power signal with 80V amplitude and 2MHZ frequency.

[0058] In the utility model, a safety verification process of therapeutic instrument is further proposed, which includes four level verifications: communication connection verification, treatment head legality verification, power supply parameter validity verification and residual emission number verification. As shown, Figure 5 Specifically, the following levels are included:

[0059] 501, communication connection verification.

[0060] The communication connection verification is to verify whether the communication connection between the therapeutic instrument and the server is normal, that is, whether the communication between the handle control module, the power control module and the display control module in the therapeutic instrument and the server is normal. The server can monitor the abnormal conditions of the therapeutic instrument, record in time, or give remote support and service to the therapeutic instrument. Among them, the communication connection between the therapeutic instrument and the server can be wired network, wireless Wi-Fi, 4G / 5G communication connection, and the specific place is not limited. Specifically, the server can send a communication request to the therapeutic instrument, and based on the communication response feedback by the therapeutic instrument, verify whether the communication connection between the therapeutic instrument and the server is normal.

[0061] It can be understood that after the communication connection verification is passed, the following three level verifications are performed, and the order of the following three level verifications is not limited here.

[0062] 502, treatment head legitimacy verification.

[0063] The treatment head legitimacy verification is to determine the type of the treatment head, and transmit the type information of the treatment head to the server. The server determines whether the treatment head and the handle are matched based on the type information of the treatment head, and determines whether the treatment head is legitimate. Specifically, the identification module is included in the treatment head, which is used to construct the identification information of the treatment head and mark the type of the treatment head. The identification module and the processor are included in the handle control module; the identification module is connected with the identification module and used to identify the identification information of the treatment head, and the processor is used to determine the type of the treatment head based on the identification information of the treatment head.

[0064] Among them, the identification module can be a pull-down resistor, the identification module can be a pull-up resistor and a grounding capacitor, and the processor includes an analog-to-digital conversion pin. The voltage value obtained by sampling through the analog-to-digital conversion pin can determine the type of the treatment head (the resistance value of the pull-down resistor carried by different types of treatment heads is different, and the voltage value obtained by sampling by the corresponding processor also has a difference).

[0065] 503, power supply parameter validity verification.

[0066] It can be understood that the power control module of the therapeutic instrument performs power supply parameter validity verification, that is, determines whether the power supply parameter of the power supply is in a preset safe range, and then determines whether the power supply is abnormal. The specific verification process is as shown above, and will not be repeated here.

[0067] Among them, after the communication connection verification is passed, the main control unit of the power control module can obtain the preset safe range from the server to perform power supply parameter validity verification based on the preset safe range.

[0068] 504, remaining number of shots verification.

[0069] The remaining number of shots verification is to verify whether the remaining number of shots fed back by the treatment head installed on the handle matches the standard remaining number of shots; wherein the remaining number of shots is the number of times of remaining energy that can be emitted. That is, it is confirmed whether the remaining number of shots of the treatment head is reduced after each treatment is completed.

[0070] The remaining firing count verification determines whether the treatment head was switched to another during treatment. Specifically, after each treatment, the treatment head sends its remaining firing count back to the server, which records it as the standard remaining firing count. If the treatment head is switched to another during treatment, the remaining firing count sent back to the server by the other treatment head after treatment will not match the standard remaining firing count, thus the remaining firing count verification fails. For example, if the server records a standard remaining firing count of 1800, and the treatment head emits energy 200 times during treatment, the remaining firing count sent back to the server should be 1600 (i.e., 1800 minus 200). If it is not 1600, the remaining firing count verification fails, confirming whether the treatment head was switched to another during treatment.

[0071] As can be seen, in this utility model, the therapeutic device undergoes multi-level safety verification during treatment, which strengthens the effectiveness of the verification; the therapeutic device is only allowed to continue treatment after all four levels of verification are met, thus enhancing the reliability and safety of the therapeutic device.

[0072] Furthermore, such as Figure 6 As shown, during a treatment session of the therapeutic device, multiple safety verification zones 620 can be inserted into the treatment area 610, and four levels of verification can be performed in each safety verification zone 620 to enhance the accuracy of safety verification.

[0073] This utility model also provides a therapeutic device system, including: a treatment head and the aforementioned power control module, wherein the power control module is used to control the power transmitted to the treatment head.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
