The present invention will be described in further detail with reference to the following examples in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, the childhood asthma screening and monitoring device provided by the embodiment of the invention includes: a respiration sensor 1, a data processing unit 2, an alarm device 3 and a communication module 4; wherein the respiration sensor 1 is remotely and wirelessly connected with the data processing unit 2, and the data processing unit 2 is provided with an alarm device 3 and a communication module 4.
The respiration sensor 1 is a bracelet type respiration sensor with high precision, the respiration frequency and depth of children can be monitored in real time in a non-contact mode, and the respiration sensor adopts technologies such as ultrasonic waves and infrared rays, so that accurate data acquisition is ensured. The specific method for realizing the respiration sensor combining the ultrasonic technology and the infrared technology comprises the following steps:
1. design and implementation of ultrasonic sensor
Transmitting ultrasonic signals: ultrasonic waves of a specific frequency are emitted by an ultrasonic transmitter.
Receiving a reflected signal: an ultrasonic receiver is used to capture ultrasonic reflected signals caused by respiratory motion (e.g., up and down movements of the chest).
Processing and analyzing the signals: the depth and frequency information of the breath is obtained by analyzing the time difference or frequency change between the transmitted and received signals and calculating the displacement of the chest.
2. Design and implementation of infrared sensor
Emitting infrared rays: infrared emitters are used to emit infrared light toward a target area.
Detecting reflected infrared rays: the reflected infrared signals are captured by an infrared receiver or a camera, so that the body surface temperature change and the up-and-down movement information of the chest are obtained.
Data analysis: by analyzing the intensity and distribution of infrared rays, respiration-related body surface temperature changes and chest movement information are obtained.
3. Data fusion and processing
Synchronous data acquisition: it is ensured that the data acquisition of the two sensors (ultrasound and infrared) is synchronized for further data fusion and analysis.
Data fusion algorithm: data from both sensors is integrated together using one or more data fusion algorithms (e.g., a Kalman filter, neural network, etc.) to obtain more accurate respiration information.
Calculating respiratory parameters: the fused data is analyzed through an algorithm, and related respiratory parameters (such as respiratory rate, respiratory depth and the like) are calculated.
4. Displaying and/or storing results
And (3) data display: the calculated breathing parameters are displayed in real time, and visual feedback is provided for a user or doctor.
And (3) data storage: the breathing parameters and raw data are stored locally or in the cloud for further analysis or review.
5. Further development of
Abnormality detection and alarm: the automatic detection and alarm functions of abnormal breathing are realized, and the health of the user is guaranteed.
Remote monitoring: the remote monitoring function is developed so that doctors or families can remotely pay attention to the breathing condition of users through the internet.
By combining the ultrasonic and infrared technologies, the breathing action and the body surface temperature change are accurately acquired, and meanwhile, the error can be effectively reduced and the accuracy and the stability of the breathing detection are improved through the data fusion algorithm processing analysis. Meanwhile, the application of multiple technologies can mutually verify and verify to a certain extent, so that the reliability of the respiratory monitoring system is further enhanced.
The data processing unit 2 is responsible for receiving and processing the data returned by the sensor in real time and comprises a processor 21 and a memory 22, wherein the processor 21 and the memory 22 are connected and are arranged on the data processing unit 2, and the data processing unit is used for storing reference data of a normal breathing mode and historical data for comparison and analysis.
The working principle of the data processing unit is as follows: the data processing unit is connected to the respiration sensor via a wireless communication protocol, such as bluetooth, wi-Fi, or other proprietary wireless protocol. When the respiration data of the child is captured by the respiration sensor, these data will be transmitted wirelessly to the data processing unit. Once the data is received, the data processing unit first performs preprocessing including cleaning, normalization, denoising, etc., for further analysis. The processed data is input into a preset algorithm for analysis. This includes statistical analysis, such as calculating the average frequency and depth of breathing, or more complex machine learning models, such as deep learning networks, for identifying complex breathing patterns. These patterns include rapid changes in respiratory rate, abnormal inhalation and exhalation ratios, or other patterns indicative of asthma symptoms. Based on the analysis results, the data processing unit will determine whether an asthma symptom is present. If an asthma symptom is identified, the data processing unit will activate the connected alarm device, emit a sound, vibration or visual signal, alerting the user or healthcare provider. The data processing unit is also responsible for storing the respiration data and the analysis results, which can be transmitted wirelessly to a remote server or healthcare provider via a built-in communication module for further analysis or for appropriate medical intervention. In general, the data processing unit implements the overall process from receiving and preprocessing data, analyzing the data, interpreting the results and raising an alarm, and finally storing and transmitting the data.
The alarm device 3 is used for detecting an abnormal breathing mode and giving an alarm and comprises a buzzer, an LED lamp and a vibration sheet; the LED lamp is arranged on the upper surface of the data processing unit, and the buzzer and the vibration sheet are arranged inside the LED lamp. When the data processing unit 2 detects a breathing pattern that does not correspond to the reference data, the alarm device 3 triggers an alarm signal in the form of sound, light and vibration, which draws the attention of the guardian.
The communication module 4, including a Wi-Fi transceiver, a bluetooth transceiver and a mobile network transceiver, is configured to communicate with a cloud server or a smart phone application program, so that a doctor, a parent or a guardian can remotely monitor the respiratory status of a child, view historical data and receive alarm information, and as shown in fig. 2, the usage method of the device for screening and monitoring asthma of a child includes the following steps:
s101, the breath sensor 1 is worn on the hand by the child, the breath sensor 1 continuously monitors the breath condition of the child, and information is remotely sent to the data processing unit 2;
s102, the data processing unit 2 analyzes the breathing mode, and if abnormality is detected, the data processing unit 2 controls the alarm device 3 to send out an alarm signal;
s103, the data processing unit 2 transmits the data to the cloud server in real time through the communication module 4, and the doctor can view the data through the application program and make treatment advice.
The working principle of the childhood asthma screening and monitoring device provided by the invention is as follows:
1. respiration sensor: the heart of this device is a respiration sensor which detects and records the breathing pattern of the child. This includes the frequency, depth of inspiration and expiration, and other parameters indicative of respiratory problems. For example, asthmatics may have periodic wheezing or shortness of breath. The sensor is a wearable device, such as a chest-mounted belt, or a device that the child can breathe directly.
2. A data processing unit: the respiration sensor wirelessly transmits the collected data to the data processing unit. This unit analyzes the data to determine if symptoms of asthma are present. This includes specific breathing patterns such as irregular inhalation/exhalation ratios, or apneas. The data processing unit uses a machine learning algorithm or other type of data analysis method to identify these patterns.
3. An alarm device: if the data processing unit detects symptoms of asthma, it activates the alarm device. This includes an audio or visual alert, or a notification sent to the healthcare provider or parent cell phone.
4. And a communication module: the data processing unit further comprises a communication module which can send the breathing data and the analysis results to a remote server or a healthcare provider. This is accomplished through Wi-Fi, bluetooth, or other wireless communication technology.
In general, this device uses data processing techniques to identify symptoms of asthma by monitoring the breathing patterns of children, and then alerts or provides information to the relevant personnel via an alert device and communication module. The purpose of this system is to identify and manage childhood asthma early, thereby preventing severe asthma attacks and improving the quality of life of the patient.
