Description

Technical Field

[0001] This utility model relates to the technical field of measuring devices for examining respiratory organs, and in particular to an autonomous lung function testing device with added 4D assistance. Background Technology

[0002] Chronic obstructive pulmonary disease (COPD) is a common chronic disease, particularly prevalent among the elderly. It is an airflow-limiting disease characterized by persistent respiratory symptoms such as cough, shortness of breath, and difficulty breathing. The severity of COPD gradually increases over time, significantly impacting patients' quality of life and social participation.

[0003] Currently, pulmonary function monitoring in hospitals is one of the main methods for diagnosing COPD. Pulmonary function monitoring can assess a patient's respiratory function, including the degree of airflow limitation and the efficiency of gas exchange in the lungs. However, because COPD screening requires a relatively complex process involving deep inhalation and exhalation, as well as adjusting breathing, people need to understand and learn the operating procedures before operating the pulmonary function monitoring device. This makes the screening process laborious and has a high failure rate, especially for the elderly who may find it difficult and slow to understand, making it even harder to complete the operation. Routine pulmonary function tests involve professional medical staff giving the subject appropriate instructions and repeatedly teaching the operating procedures, providing real-time guidance. The subject must breathe correctly under the guidance of the examiner.

[0004] Current methods for lung function testing include direct instruction, audio instruction, or video instruction. However, many test takers still say they cannot understand the instructions or are unclear about the specific breathing techniques. This not only incurs significant manpower costs and low screening efficiency, but also reduces public acceptance of COPD screening. Utility Model Content

[0005] To address the high failure rate of existing tests, this invention provides a self-testing lung function device with added 4D assistance. The 4D guidance module enhances the subject's auditory, visual, and tactile perception, thereby helping the subject understand breathing instructions, improving subject cooperation, and effectively increasing the user's success rate and the efficiency of lung function parameter testing.

[0006] This invention provides a 4D-assisted autonomous lung function testing device, comprising a sensor module for acquiring gas flow signals and chest rise / fall signals; a preprocessing module for preprocessing the acquired gas flow signals and chest rise / fall signals, connected to the sensor module; a wireless transmission module for transmitting the preprocessed gas flow signals and chest rise / fall signals; a 4D guidance module for sequentially demonstrating various breathing states and generating environmental effects based on the received gas flow signals and chest rise / fall signals, connected to the wireless transmission module; a control module for controlling the demonstration speed of the 4D guidance module based on the received gas flow signals and chest rise / fall signals, synchronizing the demonstration speed with the subject's breathing; and a power supply module for powering the device, connected to the sensor module, preprocessing module, wireless transmission module, 4D guidance module, and control module. By replacing traditional direct audio-visual guidance with a 4D guidance module, the subject's auditory, visual, and tactile sensory systems can be enhanced, thereby helping the subject understand breathing instructions and improving subject cooperation.

[0007] Furthermore, the 4D guidance module includes a video player and a 4D effects generator. The video player demonstrates various breathing states, while the 4D effects generator produces environmental effects. It provides comprehensive sensory experience encompassing hearing, sight, and touch.

[0008] Furthermore, the 4D special effects generating mechanism includes a jet fan and a speaker, both of which are fixedly mounted on the video player, with the jet fan's air outlet directed towards the subject's face. The jet fan simulates gas flow, and the speaker simulates the sound of breathing.

[0009] Furthermore, the control module identifies the subject's inhalation trigger moment based on the collected gas flow signal and chest rise and fall signal, and controls the 4D guidance module to switch from an inhalation demonstration to an exhalation demonstration. The control module typically consists of a microcontroller (MCU), responsible for controlling the operation of each module and collecting data from each module.

[0010] Furthermore, the sensor module includes a gas flow sensor, a pressure sensor, and a signal amplifier. The signal amplifier is electrically connected to the control module. The gas flow sensor is positioned at the mouthpiece of the breathing mouthpiece to collect changes in gas flow. The pressure sensor collects changes in the rise and fall of the subject's chest cavity. Both the gas flow change signal and the subject's chest cavity rise and fall signal are amplified by the signal amplifier and then sent to the control module. The gas flow sensor accurately captures the speed of gas flow during the subject's breathing, and the pressure sensor measures and monitors changes in chest pressure related to breathing.

[0011] Furthermore, the pressure sensors are chest and abdominal straps worn on the subject's chest and abdomen. The chest and abdominal straps can be stably worn on the subject's chest and abdomen, facilitating real-time measurement of chest cavity rise and fall changes.

[0012] Furthermore, the lung function testing device also includes an early warning module, which is connected to the control module. When the control module receives gas flow signals and chest rise and fall signals and identifies an error in the subject's breathing movements, it controls the early warning module to issue an alarm. The alarm prompts the subject to correct their breathing movements for better test completion.

[0013] Furthermore, the warning module includes a vibrator mounted on the chest and abdomen band and a buzzer mounted on the video player. Vibration or buzzer alerts provide simple and convenient feedback.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention provides a 4D-assisted autonomous lung function testing device. By adding a 4D guidance module that can synchronize with the subject's breathing, it enhances the subject's auditory, visual, and tactile sensory systems, thereby helping the subject understand breathing instructions and improving the subject's cooperation. This effectively increases the user's success rate, improves the efficiency of lung function parameter testing, effectively reduces the labor cost of testing, and increases public acceptance of lung function parameter testing.

Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] To improve the success rate of subjects' operations, a self-monitoring device for lung function with added 4D assistance was designed, such as... Figure 1 As shown, it includes a sensor module 10, a preprocessing module 20, a wireless transmission module 30, a 4D guidance module 40, a control module 50, and a power supply module 60. The power supply module 60 is electrically connected to the sensor module 10, the preprocessing module 20, the wireless transmission module 30, the 4D guidance module 40, and the control module 50.

[0022] Sensor module 10 is used to collect gas flow signals and chest rise and fall signals. Preprocessing module 20 is used to preprocess the collected gas flow signals and chest rise and fall signals. Preprocessing module 20 is connected to sensor module 10. Wireless transmission module 30 is used to transmit the preprocessed gas flow signals and chest rise and fall signals. Wireless transmission module 30 is connected to preprocessing module 20. 4D guidance module 40 is used to orderly demonstrate various breathing states and generate environmental effects based on the received gas flow signals and chest rise and fall signals. 4D guidance module 40 is connected to wireless transmission module 30. Control module 50 is used to control the demonstration speed of 4D guidance module 40 based on the received gas flow signals and chest rise and fall signals, so that the demonstration speed is synchronized with the subject's breathing. Power module 60 is responsible for converting mains power into various DC voltages required by the system to power the various modules of the system. The control module 50 is communicatively connected to the 4D guidance module 40 and the breathing mouthpiece 104. The control module 50 can analyze the physiological data collected by the sensor module 10 to determine the subject's breathing state, and then adjust the demonstration speed of the NPC in the 4D guidance module 40 so that the demonstration speed and environmental effects of the 4D guidance module 40 are synchronized with the subject's breathing. This can enhance the subject's auditory, visual and tactile perception systems, thereby helping the subject understand the breathing instructions and improving the subject's cooperation. This effectively improves the user's operation success rate, increases the detection efficiency of lung function parameters, effectively reduces the labor cost of detection, and increases people's acceptance of lung function parameter detection.

[0023] The lung function testing device connects to the terminal device via wired or wireless means, such as a wired connection via a data transmission cable or a wireless connection via protocols like Bluetooth, Wi-Fi, or NFC. The terminal device and the 4D guidance module 40 can also connect via wired means (e.g., USB cable, Ethernet cable) or wireless means (e.g., Bluetooth Low Energy, Wi-Fi, or NFC). The terminal device can connect to different types of lung function testing devices, or connect to multiple lung function testing devices simultaneously. The terminal device can be a smartphone, tablet, laptop, desktop computer, smart speaker, smartwatch, in-vehicle terminal, etc., but is not limited to these.

[0024] Specifically, the 4D guidance module 40 includes a video player 401 and a 4D special effects generating mechanism. The video player 401 is used to demonstrate various breathing states, and the 4D special effects generating mechanism is used to generate environmental special effects. The 4D special effects generating mechanism includes a jet fan 402 and a speaker 403. Both the jet fan 402 and the speaker 403 are fixedly mounted on the video player 401, and the air outlet of the jet fan 402 is directed at the subject's face.

[0025] The video player 401 demonstrates various breathing states using an NPC. The video screen includes a full-body medium shot of the NPC and a close-up of their mouth. The full-body medium shot demonstrates the subject's body position and posture, and allows observation of auxiliary actions such as chest rise and fall and the state of respiratory muscle exertion during breathing. The close-up of the mouth demonstrates the mouth's movements and state during breathing. The 4D special effects generating mechanism includes airflow effects generated by a jet fan 402 and sound effects generated by a speaker 403. The airflow effects can simulate airflow at different speeds during inhalation and exhalation. The airflow directly acts on the subject's cheeks, helping the subject understand the changes in the direction and magnitude of the airflow during inhalation and exhalation. The sound effects provide different sound effects according to the speed and force of breathing, giving the subject an auditory sensory experience and helping them understand the state of the breathing airflow to guide them in completing the prescribed actions.

[0026] The control module 50 identifies the subject's inspiratory trigger moment based on the collected gas flow signal and chest rise signal, and controls the 4D guidance module 40 to switch from an inspiratory demonstration to an expiratory demonstration. The control module 50 typically consists of a microcontroller (MCU), responsible for controlling the operation of each module, collecting data from each module, calculating key indicators such as alveolar volume (VA) and pulmonary carbon monoxide diffusion capacity (DlCO), and interacting with the user by displaying data waveforms, guiding the testing process, and showing test results.

[0027] The sensor module 10 includes a gas flow sensor 101, a pressure sensor 102, and a signal amplifier 103. The signal amplifier 103 is electrically connected to the control module 50. The gas flow sensor 101 is located at the mouth of the breathing mouthpiece 104 and is used to collect changes in gas flow. The pressure sensor 102 is used to collect changes in the chest cavity rise and fall of the subject. The gas flow change signal and the chest cavity rise and fall signal are amplified by the signal amplifier 103 and then sent to the control module 50. A breathing mouthpiece 104 is used to collect the subject's breathing. A gas flow sensor 101 is installed at the mouthpiece of the breathing mouthpiece 104 to collect changes in gas flow as a respiratory signal characteristic of the subject, obtaining inspiratory respiratory signal characteristics, and sending them to a signal amplifier 103. A pressure sensor 102 is used to collect the rise and fall of the subject's chest and abdomen as a respiratory signal characteristic of the subject, obtaining chest respiratory signal characteristics and abdominal respiratory signal characteristics, and sending them to a signal amplifier 103. The signal amplifier 103 amplifies the signals sent by the sensors and sends them to the control module 50. The sensor module 10 can monitor and obtain physiological data such as the subject's oxygen saturation, airway resistance, lung compliance, and breath sounds. The pressure sensor 102 is a chest and abdomen strap 105 worn on the subject's chest and abdomen.

[0028] The lung function testing device also includes an early warning module 70, which is connected to the sensor module 10 and the control module 50. When the control module 50 receives gas flow signals and chest rise and fall signals from the sensor module 10 and identifies an error in the subject's breathing, it controls the early warning module 70 to issue an alarm. The early warning module 70 includes a vibrator 701 mounted on the chest and abdomen band and a buzzer 702 mounted on the video player 401. The vibrator 701 and buzzer 702 provide prompts to the subject, allowing the subject to adjust their breathing and improve testing efficiency.

[0029] like Figure 2As shown, in the video player 401 of the 4D guidance module 40, the NPC sits upright with his nose clipped shut to ensure no airflow. His mouth covers the mouthpiece of the lung function test breathing mouthpiece 104 to ensure no air leakage or blockage during the entire breathing process. He demonstrates the following breathing actions in front of the mouthpiece: (1) Normal breathing: Breathe naturally and calmly through the mouth, inhale and exhale normally, with the chest rising and falling naturally. Continue breathing for 1 minute, maintaining an inhalation and exhalation volume of 400ml and a breathing rate of 16-18 breaths / min. (1) Synchronize the structure with the video, set the inhalation and exhalation airflow speed to a square wave form of 1L / s, and the sound is a normal and soothing breathing airflow sound effect; (2) Take a slow deep breath, exhale through the mouth until it is completely exhaled, then inhale deeply and slowly until it reaches the maximum, and after reaching the inhalation plateau, exhale slowly and deeply until it is completely exhaled. During this breathing action, maintain a medium airflow speed until the inhalation and exhalation are complete. This action is demonstrated once in a cycle, and the special effects show the effect of continuous inhalation and exhalation with a medium airflow speed; (3) Breathe forcefully, inhale deeply until it is the maximum, and then blow out all the air with the greatest force and the fastest speed. Gas until no more can be exhaled, then take a deep breath as much as possible. This action is repeated once. This breathing action needs to demonstrate the rapid force of the breathing action, that is, the chest and abdomen band 105 detects that the rib cage has a rapid and large expansion and the state of forceful exhalation under the action of the respiratory muscles. The special effect demonstrates forceful deep inhalation, forceful exhalation, and then deep inhalation. The exhalation flow rate is set to a decreasing flow rate waveform with a peak flow rate of 8L / s and an exhalation time of >6s. The inhalation waveform is a decreasing wave with a peak flow rate of 5L / s. The sound effects should demonstrate the high speed and force of breathing; (4) Rapid deep breathing, forceful and rapid deep breathing. Inhale and exhale deeply. The key point of this action is speed, that is, the breathing frequency is about 80-100 times / min. The amount of inhalation and exhalation does not need to be the maximum. It is enough to reach 50%-60% of the maximum amount. This action is demonstrated for 10 seconds. The special effect is to demonstrate the speed of deep breathing. The sound effect is the high-speed and loud sound quality presented by the rapid inhalation and exhalation of airflow. (5) Hold your breath. After slowly inhaling deeply to the maximum, hold your breath for 10 seconds, and then exhale normally. This action is repeated once. The special effect simulates the state of stillness after the airflow is inhaled. At this time, there is no sound of airflow. Then the airflow is slowly exhaled.

[0030] When guiding subjects through pulmonary function tests, the operator simply clicks on the corresponding breathing exercise demonstration video. Subjects can then follow the video instructions, grasp the key points, and perform the required breathing movements. Even if the breathing movements are inaccurate, the warning module 70 will provide a prompt, allowing subjects to adjust their breathing in time for effective testing. This development of the testing method has improved subject cooperation and acceptance during pulmonary function tests, significantly increased the success rate, reduced communication costs and workload for medical staff, and improved doctor-patient relationships.

[0031] The above description is illustrative only and not restrictive of this utility model. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all such modifications, variations or equivalents will fall within the protection scope of this utility model.
