[0002] Ultrasonic therapy devices convert electrical energy into acoustic energy and apply it to the body. They leverage the mechanical, thermal, and physical and chemical effects of ultrasound to soften tissue, enhance penetration, promote metabolism, improve blood and lymphatic circulation, and stimulate the nervous system and cellular function, thereby preventing and treating disease. Existing ultrasonic therapy devices primarily consist of two components: a main unit and a treatment head. The main unit generates the AC signal required for the treatment head to operate and typically consists of a power module, control circuitry, and drive circuitry. Driven by this signal, the treatment head converts electrical energy into acoustic energy, which then acts on the body to achieve therapeutic results.

[0003] Because the operating frequency of the ultrasonic therapeutic device is relatively high (such as the commonly used 1MHz or 3MHz), the microphone (the device that transmits the sound energy generated by the treatment head transducer to the treatment area) will heat up seriously during operation.

[0050] Example 1

[0051] Figure 1 A schematic diagram of the connection of the first ultrasonic output device provided in an embodiment of the present application; Figure 2 A schematic diagram of the gating of the first switching circuit provided in an embodiment of the present application; Figure 3 FIG4 is a schematic diagram of the selection of the second switching circuit provided in an embodiment of the present application; FIG4(a) is an exploded view of an ultrasonic transmission module provided in an embodiment of the present application; FIG4(b) is a top view of the transmission working surface of an ultrasonic transmission module provided in an embodiment of the present application; FIG4(c) is a cross-sectional view of an ultrasonic transmission module provided in an embodiment of the present application.

[0052] like Figure 1 As shown, the ultrasonic output device provided in the embodiment of the present application includes: a plurality of ultrasonic sound transmission modules 101, a switch circuit 102, a first controller 103 and a fixing member;

[0053] Each ultrasonic transmission module 101 is mounted on a fixture to adapt to the surface shape of the output portion after being fixed to the output portion by the fixture to form an ultrasonic output surface. The ultrasonic transmission module 101 includes a piezoelectric transducer 402 and a microphone 401. The output end of the piezoelectric transducer 402 is connected to the input end of the microphone 401. The output end of the microphone 401 serves as a transmission working surface 405.

[0054] A first end of the switch circuit 102 is connected to the output end of the ultrasonic drive circuit, and a second end of the switch circuit 102 is connected to the input end of the piezoelectric transducer 402;

[0055] The output terminal of the first controller 103 is connected to the control terminal of the switch circuit 102 , so as to control the connection relationship between each ultrasonic sound transmitting module 101 and the ultrasonic driving circuit by turning on the switch of the switch circuit 102 .

[0056] In practical applications, an ultrasonic therapeutic device primarily comprises a main unit and a treatment head. In the specific implementation of the present invention, multiple ultrasonic transmission modules 101 can be mounted on a fixture to serve as the treatment head of the ultrasonic therapeutic device. The switch circuit 102 and first controller 103 can be packaged within the main unit of the ultrasonic therapeutic device. The input end of the ultrasonic drive circuit is connected to a power supply.

[0057] The ultrasonic transmission module 101 primarily comprises a piezoelectric transducer 402 and a microphone 401, which are used to convert the electrical signal output by the ultrasonic drive circuit into an ultrasonic signal that acts on the output site. The piezoelectric transducer 402 converts electrical energy into ultrasonic sound energy, while the microphone 401 transmits the sound energy from the piezoelectric transducer 402 to the output site. In actual use, a coupling agent is typically added between the microphone 401 and the output site (skin) to increase transmission efficiency.

[0058] In order to achieve uniform ultrasonic output, both the piezoelectric transducer 402 and the microphone 401 can adopt a thin sheet structure. The input end of the piezoelectric transducer 402 is the positive power supply surface of the piezoelectric transducer 402, the ground surface of the piezoelectric transducer 402 is mounted in contact with the upper surface 407 of the microphone 401, and the lower surface of the microphone 401 is the sound transmission working surface 405, so that the microphone 401 provides a larger area of ​​the sound transmission working surface 405.

[0059] As shown in Figures 4(a), 4(b), and 4(c), piezoelectric transducer 402 is mounted in contact with microphone 401. The positive power supply surface of piezoelectric transducer 402 is connected to the second end of switch circuit 102 via a positive line. The ground surface of piezoelectric transducer 402 is mounted in contact with the upper surface 407 of microphone 401. The lower surface of microphone 401 serves as a sound transmission working surface 405.

[0060] Microphone 401 is made of a sound-conducting material (aluminum or stainless steel). The upper surface 407 of the piezoelectric transducer 402 serves as the positive power supply surface for applying voltage. Specifically, the positive wire from the ultrasonic drive circuit and switch circuit 102 is soldered to the positive power supply surface of the piezoelectric transducer 402 (the positive wire is soldered to the silver-plated layer 405 on the upper surface of the piezoelectric ceramic). The lower surface of the piezoelectric transducer 402 serves as the ground plane and is integrally mounted with the upper surface 407 of the microphone 401. Therefore, a ground wire can be soldered to the microphone 401. Furthermore, the positive and ground wire cables 406 can be combined into a cable bundle.

[0061] To facilitate placement and use, as shown in FIG4(a), FIG4(b), and FIG4(c), the ultrasonic transmitter module 101 in the embodiment of the present application may further include an insulating housing 403 and an insulating cover 404;

[0062] The insulating housing 403 and the insulating cover 404 are fitted together to form an inner cavity for accommodating the piezoelectric transducer 402 and the microphone 401;

[0063] The insulating housing 403 is provided with a through hole for embedding the microphone 401 and a ground wire groove for placing the ground wire;

[0064] The insulating cover 404 is provided with a positive electrode wire groove for placing the positive electrode wire.

[0065] The insulating housing 403 and insulating cover 404 can both be made of plastic and integrated with the piezoelectric transducer 402 and microphone 401 through processes such as inlaying. The housing formed by the insulating housing 403 and insulating cover 404 has openings on both sides of its upper and lower surfaces. The outer surface of one opening is flush with the sound-transmitting working surface 405 of the microphone 401, while the opening on the other side is for mounting the piezoelectric transducer 402.

[0066] The fixture serves as both a component supporting multiple ultrasonic transmission modules 101 and a fixture for securing these ultrasonic transmission modules 101 to the output site. While each ultrasonic transmission module 101 is secured to the fixture, they are also connected to each other in a deformable manner, such as by silicone mounting or by pins, ropes, or the like. This allows the treatment head to be secured to the output site via the fixture, allowing the ultrasonic transmission modules 101 carried by the fixture to adapt to the surface shape of the output site to form an ultrasonic output surface. The fixture can be a bracelet-like fixture, secured by Velcro, a lace, or a snap-fit ​​method.

[0067] If the fixing member is a silicone shell, each ultrasonic transmission module 101 can be embedded and installed in the silicone shell, and the silicone shell is hollowed out at the sound transmission working surface 405 of the sound transmission block of each ultrasonic transmission module 101 to better output ultrasonic sound energy.

[0068] The switch in the switch circuit 102 can be an electromagnetic relay. Figure 2 and Figure 3 As shown, the switch circuit 102 may include two switches: a first-stage frequency selector switch and a second-stage mode control switch. The mode control switches can be configured to correspond one-to-one with the ultrasonic transmission modules 101, while the frequency selector switches correspond one-to-one with the frequency channels provided by the ultrasonic drive circuit in the ultrasonic therapeutic device. By combining the frequency selector switch and the mode control switch, different ultrasonic transmission modules 101 can be connected to the output of the ultrasonic drive circuit.

[0069] The first controller 103 controls the connection between the different ultrasonic transmission modules 101 and the ultrasonic drive circuit by controlling the switching of the switches in the switching circuit 102. This allows the ultrasonic transmission modules 101 on the treatment head to operate alternately, simulating the effect of moving the position of a conventional handheld treatment head. The first controller 103 can be a separate controller, or it can be integrated with the controller originally used to control the ultrasonic drive circuit in the main unit of the ultrasonic treatment device to control the switching circuit 102.

[0070] The order and duration in which the first controller 103 activates the switching circuit 102 can be determined by the operating mode of the ultrasonic therapeutic device. Specifically, the operating order and operating duration of the ultrasonic transmission modules 101 corresponding to different operating modes can be set. The ultrasonic transmission modules 101 can be controlled to operate sequentially, randomly, or in a targeted manner, thereby increasing the operating frequency of the ultrasonic transmission modules 101 at key locations and reducing the operating frequency of the ultrasonic transmission modules 101 at other locations. The first controller 103 has an integrated timer and logic circuit on the board to control the operating order and duration of the ultrasonic transmission modules 101.

[0071] The following describes how the ultrasonic output device provided in the embodiment of the present application can realize two working modes, 1 MHz treatment frequency and 3 MHz treatment frequency, which are commonly used in conventional ultrasonic therapeutic devices.

[0072] like Figure 2 and Figure 3 As shown, the five ultrasonic transmission modules (ultrasonic transmission module A, ultrasonic transmission module B, ultrasonic transmission module C, ultrasonic transmission module D, and ultrasonic transmission module E) correspond to the mode control switch A, mode control switch B, mode control switch C, mode control switch D, and mode control switch E in the switch circuit 102, respectively. The frequency selection switch A corresponds to the 1MHz treatment frequency channel, and the frequency selection switch B corresponds to the 3MHz treatment frequency channel, i.e., the two frequency output channels of the ultrasonic drive circuit. It should be noted that Figure 2 and Figure 3 Different gating modes corresponding to the same connection method of the switch circuit 102.

[0073] The first working mode provided in the embodiment of the present application is a single frequency scanning working mode. Figure 2As shown, at this time, one of the 1MHz treatment frequency channel and the 3MHz treatment frequency channel is selected as the drive signal output channel. Taking the 1MHz treatment frequency channel as an example, frequency selector switch A is in the on state and frequency selector switch B is in the off state. Ultrasonic transmitter modules A through E are sequentially switched on and off under the control of the timer and logic circuit of the first controller. For example, starting with ultrasonic transmitter module A, mode control switch A can be switched on and off for a first preset time, then off. Simultaneously, mode control switch B corresponding to ultrasonic transmitter module B is switched on and off for a first preset time, and so on. This scanning operating mode is equivalent to the mode control switch scanning the ultrasonic transmitter module 101 under the control of the first controller 103. The scanning time can mimic the speed control of existing handheld treatment heads. For example, the first preset time can be set to 1 second. The scanning order can be based on the arrangement order of the ultrasonic transmitter modules 101 or a random order.

[0074] The second working mode provided in the embodiment of the present application is the mixing frequency scanning working mode, such as Figure 3 As shown, the ultrasonic transmitter modules A to E can also be turned on and off sequentially. The difference is that when the ultrasonic transmitter modules A, C, and E are turned on, the first controller controls the frequency selection switch A to be in the on state and the frequency selection switch B to be in the off state; when the ultrasonic transmitter modules B and D are turned on, the first controller 103 controls the frequency selection switch A to be in the off state and the frequency selection switch B to be in the on state, thereby realizing a mixed frequency scanning mode in which two frequencies are alternately scanned.

[0075] The switching circuit 102 can also implement other frequency mixing modes, such as a frequency mixing scanning mode in which all mode control switches are turned on and the frequency selection switch A and the frequency selection switch B perform scanning alternately.

[0076] In addition to the above-mentioned working modes, the first controller 103 can control the ultrasonic transmitter module 101 to work in other working modes according to the installation method of the ultrasonic transmitter module 101, the current working mode setting, etc., which is equivalent to using one or more frequencies of ultrasonic signals to scan each ultrasonic transmitter module 101 in a certain order. Therefore, even if the treatment head is fixed at the output position and not handheld and moved, its dynamic scanning process is equivalent to the output effect of the moving treatment head, thereby avoiding burns caused by the continuous action of the treatment head on one area and realizing the hands-free function.

[0077] In order to facilitate the output to multiple output parts and improve the output efficiency, a first controller 103 can be set to simultaneously control the scanning on multiple treatment heads, that is, each treatment head is provided with multiple ultrasonic sound transmission modules 101 fixed to the output part by a fixing member, and multiple treatment heads are fixed to multiple output parts, and multiple treatment heads can work simultaneously.

[0078] Example 2

[0079] FIG5( a ) is a schematic diagram of an ultrasonic output device provided in an embodiment of the present application from a first angle;

[0080] FIG5( b ) is a schematic diagram of an ultrasonic output device provided in an embodiment of the present application from a second angle; FIG5( c ) is a partially enlarged schematic diagram of an ultrasonic output device provided in an embodiment of the present application; Figure 6 A schematic diagram of the structure of a pin shaft 504 provided in an embodiment of the present application.

[0081] In the first embodiment, it is mentioned that the fixing member 501 can be a bracelet-type fixing device, which can be fixed by setting Velcro 502, fixing with a lace, or fixing by a buckle method. In order to install multiple ultrasonic transmission modules 101 on the fixing member 501 while ensuring that the connection relationship between each ultrasonic transmission module 101 can adapt to the surface shape of the output part to form an ultrasonic output surface after the fixing member 501 is fixed to the output part, the ultrasonic transmission modules 101 can be installed with silicone or connected by means of pins 504, ropes, etc. Based on this, the second embodiment of the present application is described as a fixing member 501 using a bracelet-type fixing method and Velcro 502, and a connection method using pins 504 between multiple ultrasonic transmission modules 101.

[0082] As shown in Figures 5(a), 5(b), and 5(c) (this figure only illustrates the structure of the ultrasonic transmitter module 101 and the fixing member 501 of the ultrasonic output device), the ultrasonic transmitter module 101 is provided with a pin locking hole and a pin rotation hole for fixing a pin 504. Adjacent ultrasonic transmitter modules 101 are connected by the pin 504 passing through the pin locking hole and the pin rotation hole. The pin rotation holes of adjacent ultrasonic transmitter modules 101 rotate about the pin 504 to adapt to the surface shape of the output area. The ultrasonic transmitter module 101 adjacent to the fixing member 501 is fixedly connected to the fixing member 501 using a fixing shaft 503.

[0083] The surface structure of the pin 504 is as follows Figure 6As shown, the portion of the surface corresponding to the pin locking hole is a knurled structure, while the portion of the surface corresponding to the pin rotation hole is a smooth structure. After assembly, the pin 504 can rotate relative to the pin rotation hole but cannot rotate relative to the pin locking hole. A set of pin locking holes and pin rotation holes are provided at both ends of the side of the ultrasonic transmitter module 101 to facilitate the fixed connection of adjacent ultrasonic transmitter modules 101, so that their relative positions can only be changed around the pin 504. After the fixing member 501 is fixed to the output part (such as the wrist), each ultrasonic transmitter module 101 adapts to the surface structure of the output part as the fixing member 501 stretches, rotates around the pin 504, and is arranged along an arc to fit the surface of the output part.

[0084] As shown in Figures 4(a) and 4(b), if the ultrasonic microphone module 101 includes an insulating shell 403 and an insulating cover 404 for enclosing the piezoelectric transducer 402 and the microphone 401, mounting holes are provided on the insulating shell 403 at positions corresponding to the pin locking hole and the pin rotation hole to facilitate the installation of the pin 504.

[0085] Typically, each ultrasonic transmitter module 101 requires two wires: a positive power supply line and a ground line. When connecting the ultrasonic transmitter modules 101 via the pin 504, the pin 504 can be made of a conductive material (such as stainless steel). When integrating the microphone 401 with the grounding surface of the piezoelectric transducer 402, a pin locking hole can be specifically provided in the microphone 401. Each microphone 401 conducts electricity through the pin locking hole and the pin 504. In this case, each ultrasonic transmitter module 101 can share the same ground line, significantly reducing the number of cables 406 required.

[0086] On the treatment head shown in Figures 5(a), 5(b), and 5(c), multiple ultrasonic transmission modules 101 are radially arranged in a single row. Alternatively, multiple ultrasonic transmission modules 101 can be arranged in an array, i.e., a multi-row structure, to achieve more refined scanning output or to treat a larger output area after fixation.

[0087] Example 3

[0088] Figure 7 This is a connection diagram of the second ultrasonic output device provided in an embodiment of the present application.

[0089] On the basis of the above embodiments, to provide more diverse application scenarios, adapt to output parts of various shapes, provide more refined output effects, and facilitate replacement of faulty parts, the ultrasonic output device provided in the third embodiment of the present application further includes a detection circuit 701 connected to the input end of the first controller 103 for obtaining the in-position status of the ultrasonic transmission module 101;

[0090] Each ultrasonic transmitter module 101 is detachably mounted on the fixing member 501 and detachably connected to the second end of the switch circuit 102 .

[0091] By configuring each ultrasonic transmitter module 101 to be detachably mounted on the fixing member 501 and the switch circuit 102, and reporting the in-place status detection signal of each ultrasonic transmitter module 101 to the first controller 103 via the detection circuit 701, the user can assemble the treatment head as needed and easily replace a faulty ultrasonic transmitter module 101.

[0092] The above describes in detail various embodiments corresponding to the ultrasonic output device. On this basis, the present application also discloses a control method for the ultrasonic output device and an ultrasonic therapeutic apparatus corresponding to the ultrasonic output device.

[0099] Controlling the gating of the switch of the switching circuit according to the gating mode of the switching circuit;

[0100] The gating mode of the switch circuit includes a switch gating combination of the switch circuit and a duration corresponding to the switch gating combination.

[0101] In a specific implementation, after the first controller determines the target frequency output channel based on the frequency selection command, it determines the output frequency of the ultrasonic drive circuit. The first controller determines the control mode for the target frequency output channel and the control mode for the ultrasonic transmission module, specifically, the operating sequence and frequency of each ultrasonic transmission module at each output frequency. Furthermore, the first controller can determine the gating mode for the switch circuit, specifically, controlling the operating sequence and frequency of each ultrasonic transmission module at each output frequency by selecting the switch gating combination and the corresponding duration of the switch gating combination.
