Description

Technical Field

[0001] The invention relates to the field of medical auxiliary equipment, in particular to a vibrating expectorant with an intra-airway vibration function. Background Art

[0002] Currently, there are two main methods for clearing sputum from the airway: mechanical vibration expectoration and drug-assisted expectoration. Traditional mechanical vibration expectoration equipment promotes the loosening and discharge of sputum in the airway by applying vibration or pressure to the patient's chest. Most of the existing airway vibration expectoration technologies focus on external vibration, generating mechanical vibrations through external vibration equipment, but their conduction effect is limited and requires continuous operation by medical staff, which is not suitable for patients to operate independently. In addition, the existing equipment is bulky, cumbersome to operate, and the treatment time is long, which can easily cause discomfort. Summary of the invention

[0003] The main purpose of the present invention is to provide a vibrating expectorant with intra-airway vibration function, which can effectively solve the problems in the background technology.

[0004] To achieve the above object, the technical solution adopted by the present invention is: a vibrating expectorant with intra-airway vibration function.

[0008] Furthermore, the charging module installed inside the control device is connected to the charging interface through a power input port, and the charging interface is a USB Type-C interface that supports bidirectional transmission.

[0009] Furthermore, the internally installed input and output module assembly includes a UART communication module, an I2C communication module and an SPI communication module, and all input and output signals are connected to corresponding interfaces on the circuit board through a set of connection holes with a diameter of Φ1mm; the module supports data exchange with external devices, and adjusts the data transmission rate and synchronization through the algorithm processing module.

[0010] Furthermore, the connection line includes a wire, one end of which is electrically connected to the input-output module assembly in the control device, and the other end is connected to the input port in the sound amplification device through a connection aperture of Φ2mm.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The vibrating expectorant with intra-airway vibration function of the present invention effectively improves the loosening and discharge efficiency of sputum in the airway by directly applying vibration waves in the airway. Compared with the traditional external vibration expectoration device, the present device does not rely on external vibration conduction, thereby avoiding the problem of limited external vibration transmission effect, especially when dealing with sputum in the distal airway, it can produce a stronger vibration effect to ensure the comprehensiveness of the treatment. In addition, the vibration in the airway can directly act on the surface of the airway wall, promote the liquefaction, dilution and shedding of sputum, effectively improve the expectoration speed, and help patients clear sputum more quickly and thoroughly.

[0012] In addition, the device is designed to be portable and user-friendly, so patients can operate it at home, reducing their dependence on medical staff. This convenience allows patients to flexibly adjust the treatment time and frequency, ensuring the continuity and effectiveness of long-term treatment. The intelligent control module of the device can dynamically adjust the vibration frequency according to the patient's body position, sputum status, etc., to optimize the treatment effect. At the same time, patients can use the device in their daily lives, avoiding frequent trips to the hospital, reducing the pressure on medical resources, and reducing the physical and psychological burden caused by long-term medical treatment.

[0019] The control device is responsible for the generation and processing of all signals, as well as the control of the equipment. The control device is connected to the sound amplification device through a connecting line. The function of the connecting line is to transmit the signal from the control device to the sound amplification device to ensure the effective conduction of the signal. The connecting line ensures the stable transmission of electrical signals through connection methods such as wires and signal interfaces.

[0020] After receiving the audio signal from the control device, the sound amplifier converts it into vibration waves. The sound amplifier includes a woofer and a mid-high frequency speaker, which generate vibration waves of different frequencies according to different treatment modes. The front end of the sound amplifier is equipped with a consumable device, which is in direct contact with the patient's airway, such as a mouthpiece or a catheter. Through this configuration, the vibration waves can be effectively transmitted to the patient's airway to help loosen and discharge sputum.

[0021] There is a circuit board inside the control device, and all control signals, audio signals and power supply are allocated and transmitted through the circuit board. The central processing unit controls and executes instructions for the entire system, including the selection of treatment mode, adjustment of vibration frequency, signal processing, etc. It is the core part of all information flow and signal processing, ensuring that the device runs according to the set program. The algorithm processing module converts the patient's input information into specific control instructions, and adjusts the signal generation parameters according to the real-time feedback of the device to ensure the personalization and efficiency of the treatment process. The high-quality signal generator generates high-quality audio signals and converts digital signals into analog signals through the DAC module. It provides the source power for the output of audio signals, ensuring the accuracy and efficiency of the signals.

[0022] The control device is also equipped with a base plate, which provides support and fixation, and ensures stable connection between various components. The modules on the base plate are responsible for power management and signal processing respectively. The power system provides power to the device, including a battery management system, which is responsible for regulating and distributing power to ensure stable operation of the device. The power system ensures stable power supply to components such as the central processor and signal generator by connecting with other parts of the control device. The DAC module converts the digital audio signal generated by the central processor into an analog signal so that the signal can be amplified by the amplifier circuit and drive the speaker. The audio amplifier circuit amplifies the analog audio signal output by the DAC module so that the signal can drive the speaker to produce sufficient volume and vibration waves. The audio amplifier circuit ensures that the quality and power of the signal meet the expected effect. The power amplifier device amplifies the audio signal to ensure that the low-frequency, medium-frequency and high-frequency speakers can generate strong enough vibration waves to effectively conduct to the airway to help expectoration. The input and output module assembly is responsible for communicating with external devices and supports data input and output. The device can be remotely controlled or data recorded, which enhances the intelligence of the device.

[0023] Furthermore, an output display screen 101 is installed above the control device 1, an input button 102 is installed above the control device 1, a charging interface 103 is installed above the control device 1, and a connection interface 104 is installed above the control device 1. The output display is located above the control device and is the main interactive interface between the device and the user. The display uses OLED technology and can clearly display key information such as treatment mode, remaining power, treatment time, etc. The functions of the display include: Real-time display: Displays the current working status of the device, such as treatment mode, remaining battery power, current treatment duration and other information.

[0024] Intuitive feedback: When the device is in working state, the screen will display the ongoing treatment mode and the estimated completion time, providing user operation feedback.

[0025] Fault indication: When a device fails, the display can flash or display a warning message to help users identify the problem and take appropriate measures.

[0026] The input buttons are located above the control device, and users operate the device by pressing the buttons. These buttons are waterproof, highly sensitive and have a long service life. The functions of the input buttons include: Mode selection: Users can select different treatment modes through the input button. Each mode corresponds to a different frequency of vibration waves to meet the sputum loosening needs of different airway areas.

[0027] Start / Stop Operation: The user starts the device or pauses treatment by pressing a button. Pressing the button for a while can turn off the device to avoid accidental operation.

[0028] Time Setting: The button can also be used to set the duration of the treatment, ensuring that each treatment has a clear time limit.

[0029] The input button is connected to the central processor through a circuit, receives user input and transmits it to the processing unit for control, ensuring the smooth progress of the treatment process.

[0030] The charging port is located above the control device and is mainly used to charge the device. The charging port is designed as a USB Type-C port, which supports convenient charging operations and meets the general standards of current electronic products. Users can use a standard USB cable to connect the device to a charger or power outlet for charging. The device is equipped with a built-in battery, and the charging port enables the device to be charged in time after the battery is exhausted, ensuring that the device has enough power for the next use.

[0031] Furthermore, a bass speaker 301 is installed inside the sound amplifying device 3, a mid-high frequency speaker 302 is installed inside the sound amplifying device 3, a coupling resonance cavity 303 is installed inside the sound amplifying device 3, an amplifier circuit 304 is installed inside the sound amplifying device 3, and a supporting rib 305 is installed inside the sound amplifying device 3.

[0032] The main function of a woofer is to generate low-frequency vibration waves, which mainly act on the larger airways. Low-frequency vibration waves help loosen and liquefy the phlegm in these large airways, thereby helping patients to expel the phlegm. The woofer uses a larger diaphragm and a stronger drive system to produce powerful low-frequency vibrations. Its operating frequency range is between 20Hz and 200Hz, which is suitable for acting on large airways. When the signal is amplified, the woofer generates low-frequency vibrations, which act directly on the inner wall of the airway through the airway, making the phlegm looser and facilitating expectoration.

[0033] The mid-high frequency speaker is used to generate mid-frequency and high-frequency vibration waves, mainly for smaller airways. These vibration waves can penetrate deep into the distal airways, effectively promoting the loosening and discharge of sputum in the deep airways. The mid-high frequency speaker uses a smaller diaphragm and a more sophisticated tuning design, which is suitable for producing higher frequency sounds. It can accurately generate subtle vibrations in the airway to help loosen sputum in the deep airway. The mid-high frequency vibration waves can penetrate deep into various parts of the airway, and by stimulating the resonance of the airway wall, the sputum in the distal airway is loosened, thinned, and effectively discharged.

[0034] The coupled resonant cavity enhances the transmission efficiency of the vibration wave. It increases the intensity and stability of the sound waves emitted by the speaker through the resonance effect, ensuring that the vibration waves can be efficiently transmitted to the patient's airway. The coupled resonant cavity is a cavity structure whose size and shape are carefully designed to resonate with the frequency of the speaker. This cavity amplifies and guides the propagation of sound waves through physical principles. After the sound waves emitted by the speaker enter the resonant cavity, the structure of the cavity amplifies the sound waves, increases the intensity and directionality of the sound waves, thereby ensuring that the vibration waves can be effectively transmitted to the airway and reducing the energy loss of vibration. The amplifier circuit amplifies the audio signal transmitted from the control device to drive the speaker to generate vibration waves. The amplifier circuit is an important part of signal processing, ensuring that the speaker can generate strong enough vibration waves to help the patient expectorate. The amplifier circuit consists of a gain adjustment part and a power amplifier part. Supports efficient and low-noise signal amplification to ensure that the signal is not distorted when passing through the speaker and the volume is loud enough to effectively vibrate the airway. After the input audio signal is amplified, the power amplifier increases the signal strength to a sufficient level to drive the speaker to vibrate and transmit it to the airway. The amplifier circuit is also responsible for adjusting the frequency and intensity of the vibration waves according to the set mode.

[0035] The CPU obtains stable voltage input through the power supply system to ensure its normal operation. It is connected to the power module through VDD and GND to provide the necessary operating voltage. The CPU is connected to the display and touch operation module through the SPI interface or I2C interface to send graphic data and receive user input. The SCL and SDA signal lines are connected to the data transmission port of the display module through the I2C bus to ensure bidirectional data exchange. The CPU transmits the signal to the algorithm processing module through the data bus, and the algorithm processing module adjusts the treatment mode, frequency, etc. according to the input data. The CPU transmits the processed control signal to the digital-to-analog conversion module through a dedicated digital signal output interface. These signals are then converted into analog signals.

[0036] The display module is integrated with the touch screen to display the device status on the screen and receive user input. The CPU sends instructions to the display module through I2C to control the screen content display and receive touch input signals. The touch input signal is passed to the CPU through the INT pin to determine the user's operation. The display module is connected to the power system through the VDD and GND interfaces to ensure its stable power supply.

[0037] The algorithm processing module is responsible for performing signal processing and adjustment tasks according to the input parameters.

[0038] The algorithm processing module is connected to the central processor via the SPI bus or I2C bus, receives processing commands and adjusts the signal. The module feeds back the processing results to the central processor for further data analysis and adjustment. The algorithm module outputs the digital signal to the DAC module, and after digital-to-analog conversion, it generates an analog signal to drive the sound amplification device.

[0039] The power system is responsible for providing a stable power supply for the entire device and ensuring that each module obtains the required voltage. The battery is connected to the power module through the battery management system to ensure the balance of battery charging and discharging and provide sufficient power support. The AMS1117 chip is used to stabilize the input power supply voltage to 3.3V. The power module provides the required voltage for the central processor, display module, signal generator, DAC module, etc. through the VDD line. The power supply of the power amplifier module and the high-quality signal generator ensures the stable amplification of the audio signal through an independent voltage stabilization circuit. The power system distributes power to each sub-module as needed, including the display module, algorithm processing module, signal generation module, etc., to ensure the overall stable operation of the device.

[0040] The DAC module converts the digital signal generated by the algorithm processing module into an analog signal, while the power amplifier module amplifies the analog signal to drive the speaker to generate vibration waves. After receiving the digital audio signal, the DAC module converts it into an analog signal. The converted analog signal is transmitted to the power amplifier circuit through the line, and the power amplifier increases the amplitude of the analog signal to drive the speaker to generate vibration waves. The power-amplified signal is output to the speakers and drives them to generate low-frequency and high-frequency vibration waves, which are transmitted to the airway to help loosen and expel sputum.

[0041] The high-quality signal generator generates audio signals for treatment and controls the frequency and amplitude of the signal. The high-quality signal generator is connected to the algorithm processing module through a dedicated interface to generate and adjust the frequency and waveform of the signal. The digital audio signal generated by the signal generator is converted into an analog signal through the DAC module and then transmitted to the power amplifier to drive the speaker.
