A cough monitoring device and system for carrying around

Abstract

The invention discloses a portable cough monitoring device and system, which mainly includes a host, a sound sensor, a surface electromyography sensor, an acceleration sensor, a filter, and a memory. The invention simultaneously records coughing sound, myoelectricity and acceleration signals during coughing, and can be used to monitor the number, frequency and intensity of coughing, with more comprehensive monitoring and accurate and reliable results; the computer-readable medium has good interactivity and can be used according to different coughing Personalized and targeted setting of patients and voice characteristics, high specificity, conducive to automatic identification and marking of coughs, analysis of cough frequency, intensity and times, automatic generation of cough reports, saving human resources, and the present invention will realize chronic cough patients The long-term cough sound can be automatically recognized, and the objective evaluation index of cough can be obtained, which can be used to guide the clinical evaluation and curative effect observation of cough patients, which has important clinical application value.

Description

technical field [0001] The invention relates to the field of cough monitoring, in particular to a portable cough monitoring device and system. Background technique [0002] Cough is a common symptom reported by patients to their physicians and is a clinical sign of respiratory disease. The doctor's evaluation of cough symptoms mainly relies on the patient's subjective description. Due to the subjectivity of the description, there is a lack of objective evaluation indicators, such as cough frequency, cough intensity, and cough count, which are important objective signs for doctors to diagnose and treat respiratory diseases. [0003] In the current field of cough monitoring, one is the sound monitoring and recognition device, which is also the most commonly used at present. It only records the sound signal alone. Since only the cough sound signal is used for recognition, it is easy to be interfered by sounds similar to coughing in the surrounding environment. The recognition a...

Problems solved by technology

[0003] In the current field of cough monitoring, one is the sound monitoring and recognition device, which is also the most commonly used at present. It only records the sound signal alone. Since only the cough sound signal is used for recognition, it is easy to be interfered by sounds similar to coughing in the surrounding environment. The recognition accuracy rate Low, low reliability, semi-automatic identification, high requirements for analysts, high labor intensity, and long time-consuming. This device has also been used in the monitoring of cough intensity recently, but it must be required that the distance between the microphones of all patients and the throat is equal. The operability is not strong, the use is inconvenient, and the reliability is low; one type is a cough recognition device using an acceleration sensor. When in use, the acceleration sensor is placed on the suprasternal notch, and the collected signals are digitized and stored in the memory card. Then the stored signal is played back in a multimedia format to assist in identifying the recorded signal. Since automatic cough recognition and detection cannot be performed, the analysis is quite time-consuming. At the same time, the sensor is difficult to fix and easy to fall off, so it cannot be verified, and there is a possibility of misjudgment. The reliability is low, and the intensity of the cough is not analyzed; there is another type of cough recognition device that uses sound + EMG signals to analyze the frequency of the cough, but not the intensity of the cough, which is labor-intensive and time-consuming. One of the devices is a vest type, which is bulky and needs to be worn by the patient, which is inconvenient to use and cannot simply and effectively recognize coughing sounds
