Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the self-service needle-pushing wound dressing device of the present invention.

[0024] Example

[0025] Figure 1 This is a schematic diagram of the self-service needle-push wound dressing device in an embodiment of the present invention.

[0026] Figure 2 This is a schematic diagram of the self-service needle-push wound dressing device in an embodiment of the present invention.

[0027] like Figure 1 and Figure 2 As shown, this embodiment provides a self-service needle-pushing wound dressing device 1000, including: a main control unit 1, a remote control 2, and a traditional Chinese medicine gel patch 3.

[0028] The main control unit 1 includes: a main circuit board 10 and a main unit housing 11. The main unit housing 11 has a rectangular parallelepiped structure.

[0029] Figure 3 This is an exploded view of the main control unit in an embodiment of the present invention.

[0030] like Figure 3 As shown, in this embodiment, the main controller has a size of ≤75mm×65mm×40mm, which is achieved by selecting domestic low-power system-on-a-chip, 0603 and 0402 packaged surface mount components and a four-layer PCB board stacking design.

[0031] The main circuit board 10 is used to generate, modulate, and control electrical stimulation signals and thermal stimulation signals.

[0032] The main circuit board 10 includes: a main control module 100, a waveform generator module 101, an operational amplifier module 102, a temperature detection circuit module 103, a temperature control circuit module 104, a first Bluetooth communication module 105, and a power supply module 106.

[0033] The main control module 100 executes control commands and coordinates the operation of each module. The main control module 100 is the control core of the entire system. In this example, the domestically produced low-power system-on-a-chip, Telink TLSR8208, is used, which integrates an MCU core, memory, Bluetooth RF, and peripheral interfaces. The main control module 100 is connected to the waveform generator module 102 via the SPI bus, to the temperature detection circuit module 103 via the I2C bus, to the temperature control circuit module 104 via the PWM interface, and to the first Bluetooth communication module 105 via the UART interface. Alternatively, the main control module 100 can be a microcontroller with integrated Bluetooth functionality.

[0034] The main control module 100 stores waveform parameters and temperature control parameters for the operating modes, including:

[0035] The technique mode is used to simulate the mechanical rhythm of different techniques in massage by solidifying composite waveforms obtained by arranging and combining basic waveforms and outputting them alternately in a time sequence.

[0036] Needle mode is used to output sharp pulse waveforms with a needle-like sensation.

[0037] In the acupuncture mode, the waveform generator module 101 generates a medium-frequency carrier wave with a frequency of 2kHz to 5kHz, which is then modulated to load a low-frequency therapeutic waveform with a frequency of 0.5Hz to 200Hz, and then amplified by power before being output to the herbal gel patch 3.

[0038] The moxibustion mode is used to achieve three heating levels of 35℃, 38℃, and 42℃ through the temperature control circuit module 104 using a PID closed-loop algorithm.

[0039] The drug delivery mode integrates constant temperature heating and mid-frequency pulsed electrical stimulation. It reduces skin impedance through thermal effects and enhances skin permeability through mid-frequency electric fields, thus synergistically promoting transdermal drug penetration.

[0040] In the drug delivery mode, constant temperature heating and low-frequency pulsed electrical stimulation are performed. The constant temperature heating temperature is 38℃-42℃, and the low-frequency pulsed electrical stimulation frequency is 1Hz-10Hz with a pulse width of 200μs-500μs.

[0041] The waveform generator module 101 is used to generate and output waveform signals. In this embodiment, the waveform generator module 101 is a DDS waveform generator chip. Driven by an external sampling clock, the chip generates digitized waveform data through a phase accumulator and a waveform lookup table based on the frequency control word and phase control word written by the main control module 100. The digitized waveform data is then converted into waveform signals by a built-in digital-to-analog converter. The generated waveform signals include exponential waves, constant amplitude waves, fan waves, triangular waves, and sine waves.

[0042] Operational amplifier module 102 amplifies the waveform signal output from waveform generator module 101. Operational amplifier module 102 employs a two-stage amplification structure. The first stage is a preamplifier, amplifying the waveform voltage amplitude output from waveform generator module 101 to a range of 0-5V. The second stage is a power amplifier, converting the voltage signal into a constant current source output with an output current range of 0-50mA. The output terminal of the power amplifier is connected to the herbal gel patch 3 via a conductive snap-fit ​​interface. An isolation transformer is also provided between the power amplifier and the herbal gel patch 3. Operational amplifier module 102 also includes an output protection circuit, including overcurrent protection, short-circuit protection, and electrode detachment detection functions. When the output current exceeds a set value or an electrode detachment is detected, the protection circuit automatically cuts off the output.

[0043] The temperature detection circuit module 103 is used to monitor the temperature of the herbal gel patch 3 in real time.

[0044] The temperature control circuit module 104 is used to control the heating power of the herbal gel patch 3. The temperature control circuit module 104 employs a PID closed-loop control algorithm. The main control module 100 calculates the duty cycle of the PWM control signal based on the deviation between the current temperature value fed back by the temperature detection circuit module 103 and the target temperature value. The PWM control signal drives the MOSFET switch to control the average power flowing through the heating wire.

[0045] The first Bluetooth communication module 105 is used for wireless communication with the remote controller 2. It employs Bluetooth Low Energy technology, enabling a one-to-one pairing between the main controller 1 and the remote controller 2. During use, the user needs to perform a pairing operation: press and hold the power button on the remote controller 2 for 5 seconds; the main controller 1 will automatically enter pairing mode, and a one-to-one pairing relationship will be established. At the communication protocol level, encrypted transmission is used between the main controller 1 and the remote controller 2, with each data packet containing a unique device identifier. When multiple devices operate simultaneously in the same space, each device transmits data on different radio frequency channels based on the Bluetooth frequency hopping mechanism to avoid mutual interference.

[0046] The power module 106 supplies power to the main circuit board 10. It consists of a battery charging chip, a DC-DC boost converter chip, and a power management chip. It is controlled via a button circuit. The power module 106 employs a tiered power supply and multiple protection design, balancing power supply stability, portability, and safety, providing power support for the stable operation of the entire system. The battery charging chip supports 5V USB input and features overvoltage, overcurrent, and overheat protection. The power management chip provides overcharge, over-discharge, and short-circuit protection for the rechargeable lithium battery. The DC-DC boost converter chip uses a high-efficiency boost-buck converter to convert the battery voltage (3.7V) to the operating voltage required by each module.

[0047] The main unit housing 11 is used to protect the main circuit board 10. The main unit housing 11 specifically includes a top shell 110 and a bottom shell 111, and a sealing ring 112 is also provided on the top shell 110.

[0048] A conductive snap-fit ​​interface is provided on one side of the main unit housing 11 for connecting to the herbal gel patch 3. A rechargeable battery 113 is also installed inside the main unit housing 11, connected to the power module 106. The rechargeable battery is a polymer lithium battery with a rated voltage of 3.7V. In drug delivery mode, the continuous working time is ≥30 minutes; in pure electrical stimulation mode, the continuous working time is ≥120 minutes.

[0049] Figure 4 This is an exploded view of the remote control in an embodiment of the present invention.

[0050] like Figure 4 As shown, remote controller 2 is wirelessly connected to host controller 1 via Bluetooth and is used to send control commands to host controller 1. Remote controller 2 has a flat cuboid structure.

[0051] The remote control 2 includes: a second Bluetooth communication module 20, a main control chip 21, a button circuit 22, four mechanical buttons 23, an LED indicator array 24, a remote control shell 25, and a remote control battery 26.

[0052] The second Bluetooth communication module 20 is located inside the remote controller 2 and is used for wireless communication with the first Bluetooth communication module 105.

[0053] The main control chip 21 is located inside the remote control 2 and is used to process button inputs and generate control commands. The main control chip 21 can also be a microcontroller with integrated Bluetooth functionality.

[0054] The button circuit 22 is located inside the remote control 2 and is electrically connected to the main control chip 21.

[0055] Four mechanical buttons 23 are located on the panel of the remote control 2, namely the power on / off button, mode adjustment button, intensity increase button, and intensity decrease button.

[0056] The LED indicator array 24 is located on the panel of the remote control 2 and is used to display the device's operating status. It is controlled by the main control chip 21 through an LED driver circuit. The LED indicator array 24 includes: a power indicator (constantly lit to indicate power on), mode indicator (corresponding to manipulation, acupuncture, moxibustion, herbal penetration, and timer), intensity indicator (digital LED display showing the intensity level), and battery level indicator (corresponding to four battery levels). When the device is working, the LED indicator array 24 displays the current status in real time.

[0057] The remote control housing 25 includes: upper and lower cover plates 250, a top cover 251, and a bottom cover 252. These are connected via protrusions and holes on the housing.

[0058] The remote control battery 26 also uses a polymer lithium battery with a rated voltage of 3.7V, and is controlled by a corresponding power module.

[0059] The herbal gel patch 3 is connected to the main control unit 1 and is used to contact the skin and output electrical and thermal stimulation signals. The herbal gel patch 3 is a disposable sterile product, sealed in an aluminum foil bag and sterilized with ethylene oxide.

[0060] The herbal gel patch 3 has a three-layer composite structure, including:

[0061] The upper conductive buckle 30 is detachably connected to the conductive buckle interface of the main controller 1. In this embodiment, the upper conductive buckle 30 is made of stainless steel and has a male buckle structure. It cooperates with the female buckle (conductive buckle interface) on the main housing 11 to achieve mechanical and electrical connection.

[0062] The intermediate flexible circuit layer 31 is connected to the upper conductive snap-fit ​​and is used to support the electrodes, heating elements, and temperature measuring elements. This embodiment uses a flexible circuit board with polyimide as the substrate.

[0063] The intermediate flexible circuit layer 31 includes:

[0064] The electrode 310 is electrically connected to the operational amplifier module 102 via the upper conductive buckle 30, and is used to output electrical stimulation signals. The electrode 310 is soldered onto the flexible circuit board and is a circular silver conductive area that is electrically connected to the electrode terminals of the upper conductive buckle 30.

[0065] The heating wire 311 is a serpentine distributed nickel-chromium alloy resistance wire, which is electrically connected to the temperature control circuit module 104 through the upper conductive buckle 30.

[0066] The NTC thermistor 312 is electrically connected to the temperature detection circuit module 105 via the upper conductive buckle 30. The accuracy of the NTC thermistor 312 is ±0.1℃. The NTC thermistor 312 is located at the center of the area covered by the heating wire 311 and is electrically connected to the temperature measuring terminal of the upper conductive buckle 30.

[0067] The lower drug-loaded gel layer 32 is connected to the intermediate flexible circuit layer 31, and is used to complete the conduction, drug release and adhesion on the skin. The lower drug-loaded gel layer 32 is made of medical conductive gel and traditional Chinese medicine extract, and is applied directly to human skin.

[0068] The working principle of the self-service needle-push wound dressing device 1000 in this embodiment is as follows:

[0069] The main controller 1 and the remote controller 2 are wirelessly connected via Bluetooth, while the main controller 1 and the herbal gel patch 3 are wiredly connected via the upper conductive buckle 30. The user sends commands via the remote controller 2. After receiving the commands, the main controller 1 generates a corresponding waveform current according to the user's selected mode, amplifies it, and outputs it to the electrode plate 310 of the herbal gel patch 3. Simultaneously, it controls the power of the heating wire 311 according to temperature control commands and achieves closed-loop control by real-time temperature monitoring through the NTC thermistor 312.

[0070] Figure 5 This is a schematic diagram illustrating the workflow of the self-service needle-push wound dressing device in an embodiment of the present invention.

[0071] like Figure 5 As shown, the operation process of the self-service needle-push wound dressing device 1000 in this embodiment is as follows:

[0072] The user takes out the herbal gel patch 3 from the packaging, presses the upper conductive buckle 30 into the conductive buckle interface of the main controller 1, and then applies the lower drug-loaded gel layer 32 to the affected skin.

[0073] First, a power-on self-test is performed. Briefly press the power button on remote control 2 to power on the main controller 1 and perform a self-test. The self-test includes: battery level detection, Bluetooth connection detection, temperature sensor detection, and electrode connection detection. After the self-test passes, the power indicator light on remote control 2 will remain on.

[0074] Next, set the mode. A short press of the mode adjustment button allows you to switch between four treatment modes (manual therapy mode, acupuncture mode, moxibustion mode, and drug delivery mode). The corresponding LED indicator lights up simultaneously, allowing the user to select the appropriate mode according to their treatment needs. In manual therapy mode, double-clicking the mode adjustment button cycles through five manual therapy sub-modes, with the LED display showing the current sub-mode's intensity level.

[0075] Next, set the intensity and time. Press the intensity increase / decrease button briefly. The output intensity increases or decreases in 1mA increments, and the intensity indicator light displays the current setting simultaneously.

[0076] In any mode, press and hold the mode adjustment button for 3 seconds to enter the timer setting mode, and press the intensity increase / decrease button to adjust the treatment time.

[0077] Treatment then begins, with the device outputting electrical and / or thermal stimulation according to the selected mode. During treatment, the user can adjust the intensity or switch modes at any time. In heat therapy mode, the temperature control circuit module 104 monitors the temperature in real time and adjusts it in a closed-loop manner to maintain the set temperature.

[0078] After the set time is reached, the device will automatically stop outputting. The user should remove the herbal gel patch 3, clean the surface that came into contact with the skin, apply a protective film for the next use, and then press and hold the power button to turn off the device.
