[0002] Cough is a common symptom of respiratory diseases, and changes in its frequency, intensity, tone and other parameters can reflect the severity, progression and treatment effect of the disease. Accurate understanding of the patient's coughing situation is crucial for disease diagnosis, treatment and prognosis evaluation. Generally, doctors mainly obtain cough information by asking patients, but patients have great differences in cultural level, medical knowledge and language expression ability, making it difficult to accurately describe the coughing situation and record the whole day's coughing situation. Especially in the early stage of the disease and the recovery period, doctors have difficulty in fully understanding the patient's coughing situation and treatment.

[0003] The patent document with publication number CN110115584A discloses a cough and respiratory monitoring system, which comprises a PVDF piezoelectric film waistband, a signal conditioning module, a single-chip microcomputer and a Bluetooth wireless transmission module. The PVDF piezoelectric film waistband collects human body signals and transmits them to the signal conditioning module. The signal conditioning module converts and processes the input signals and then transmits them to the single-chip microcomputer. The single-chip microcomputer also transmits the signals to the upper computer through the Bluetooth wireless transmission module.

[0004] It can be seen that in the actual use process of the prior art, the monitoring of the patient's cough cannot be monitored all day long through detailed data, and the patient cannot be warned for treatment according to the patient's coughing condition, and whether the treatment is effective can be judged in time according to the subsequent monitoring situation. TECHNICAL SOLUTION

[0006] To achieve the above-mentioned purpose, the present application provides a wearable cough monitoring method, comprising:

[0007] Step S1, collecting a physiological signal data set of the wearer;

[0008] The physiological signal data set includes real-time respiratory rate, real-time heart rate and real-time cough audio information;

[0013] Further, in the step S1, the real-time respiratory frequency of the wearer is collected by a respiratory frequency collection unit, the real-time heart rate of the wearer is collected by a real-time heart rate collection unit, and the real-time cough audio information of the wearer is obtained by a real-time audio collection unit.

[0014] The real-time cough audio information includes a real-time cough frequency and a real-time cough intensity value.

[0015] Further, in the step S2, a pre-set normal physiological parameter range is provided, and the real-time respiratory frequency and the real-time heart rate are compared with corresponding normal ranges in the pre-set normal physiological parameter range by a data analysis module. If the real-time physiological parameters in the physiological signal data set do not fall within the corresponding normal ranges, it is determined that they are abnormal, and the real-time physiological parameters corresponding thereto are marked as the abnormal parameters.

[0016] The pre-set normal physiological parameter range includes a pre-set normal respiratory frequency range and a pre-set normal heart rate range.

[0017] Further, in the step S3, if the abnormal parameter is the real-time respiratory frequency, the real-time cough frequency in the real-time cough audio information is compared with the pre-set cough frequency.

[0018] If the real-time cough frequency is higher than the pre-set cough frequency, the frequency spectrum characteristics of the cough audio are further analyzed.

[0019] If the real-time cough frequency is not higher than the pre-set cough frequency, no further analysis is needed.

[0020] Further, in the step S1, an audio analysis unit is further provided, if the real-time cough frequency is higher than the preset cough frequency, the audio analysis unit is used to obtain the spectrum characteristics of the cough audio, the spectrum characteristics including peak frequency and peak amplitude, in the step S3, a preset normal cough spectrum characteristic is further provided, the actual cough spectrum characteristic is compared with the preset normal cough spectrum characteristic to determine whether there is an abnormal spectrum characteristic;

[0021] If the abnormal spectrum characteristic exists, a warning is sent to the wearer for treatment;

[0024] Further, the corrected preset cough frequency is used as a new evaluation standard to evaluate the subsequent collected real-time cough frequency and obtain a subsequent evaluation result, if the subsequent evaluation result still shows abnormality, a warning is sent to the wearer for treatment.

[0025] Further, in the step S3, the preset cough intensity value and the preset cough intensity fluctuation difference are provided, if the abnormal parameter is the real-time heart rate, the real-time cough intensity value is calculated with the preset cough intensity value to obtain the real-time cough intensity fluctuation difference, and the real-time cough intensity fluctuation difference is compared with the preset cough intensity fluctuation difference;

[0026] If the real-time cough intensity fluctuation difference is less than or equal to the preset cough intensity fluctuation difference, no warning is needed;

[0027] If the real-time cough intensity fluctuation difference is greater than the preset cough intensity fluctuation difference, a warning is given;

[0028] Wherein, ΔIs=I1-I2, ΔIs is the real-time cough intensity fluctuation difference, I1 is the real-time cough intensity value, and I2 is the preset cough intensity value.

[0029] Further, the real-time cough intensity fluctuation difference is compared with the preset cough intensity fluctuation difference, if the real-time cough intensity fluctuation difference is greater than the preset cough intensity fluctuation difference, then the real-time cough intensity value and the preset cough intensity value are calculated to obtain a cough intensity deviation coefficient, and different early warnings are performed based on the size of the cough deviation coefficient.

[0030] Wherein, K=I2 / I1, wherein K is the cough intensity deviation coefficient.

[0031] Further, after the wearer is warned, the cough condition of the wearer is continuously monitored to obtain a subsequent real-time cough intensity value, the subsequent real-time cough intensity value is calculated with the preset cough intensity value to obtain a new real-time cough intensity fluctuation difference, and the new real-time cough intensity fluctuation difference is compared with the preset cough intensity fluctuation difference.

[0032] If the new real-time cough intensity fluctuation difference is still greater than the preset cough intensity fluctuation difference, it is warned that the treatment is invalid, and the wearer needs to be further examined and treated.

Advantages

[0038] Compared with the prior art, the beneficial effects of the present application are that by monitoring the physiological signal data of the wearer in real time, including real-time respiratory rate, real-time heart rate and real-time cough audio information, the body abnormality can be found early, through analysis of the physiological signal data, it can be determined whether the body is abnormal, and in the abnormal case, the cough audio is analyzed to determine whether the wearer needs to be warned for treatment, which helps to improve the accuracy and real-time of cough monitoring, reduces the possibility of misdiagnosis and missed diagnosis, and the wearer can be warned for treatment as soon as possible when the wearer coughs abnormally, and specific treatment is not necessary when normal, so that the medical resources are effectively utilized and unnecessary medical intervention is avoided.

[0039] Further, by simultaneously collecting multiple physiological indicators of the wearer through multiple collection units, the health status of the wearer is comprehensively monitored, and the accuracy and comprehensiveness of the monitoring are improved. The real-time monitoring of respiratory rate and heart rate can reflect the overall physiological state of the wearer, and the collection of cough audio information can specifically evaluate the severity of cough. Multi-dimensional data collection helps better analyze the cough condition of the wearer.

[0040] Further, by setting the normal physiological parameter range as a reference standard, the collected real-time physiological data is preliminarily screened to quickly identify possible abnormal conditions, which can effectively analyze further when abnormal, improve the accuracy and efficiency of monitoring, and at the same time, by marking abnormal parameters, a clear direction is provided for subsequent in-depth analysis and treatment.

[0041] Further, by analyzing the cough frequency to further evaluate the health status of the wearer in the case of abnormal respiratory rate, this multi-level analysis method can more comprehensively understand the health status of the wearer, avoiding misjudgment that may be caused by a single indicator. At the same time, by setting a preset cough frequency as a threshold, conditions that need further attention can be effectively screened, improving the efficiency and accuracy of monitoring.

[0042] Further, by monitoring the cough frequency and respiratory rate in real time, the frequency spectrum characteristics of the cough audio are obtained through the audio analysis unit, and compared with the preset normal cough frequency spectrum characteristics to determine whether there are abnormal frequency spectrum characteristics, which improves the accuracy of cough feature recognition. When the cough frequency spectrum is normal, the preset cough frequency value is corrected according to the respiratory rate deviation coefficient, so that the evaluation standard can be dynamically adjusted according to the real-time respiratory condition of the wearer, which helps to monitor the wearer individually.

[0043] Further, by dynamically adjusting the evaluation standard, the adaptability and accuracy of the monitoring method are improved. Through multiple evaluations and comparisons, misjudgment caused by occasional abnormalities can be effectively reduced, and at the same time, the wearer's persistent health problems can be found in time to warn the wearer for treatment, which helps to discover and handle potential health problems as soon as possible.

[0044] Further, by monitoring the cough intensity in real time and comparing it with the preset cough intensity value and the preset cough intensity fluctuation difference, it is determined whether there is an abnormal cough intensity fluctuation difference, thereby realizing early detection and early warning of cough abnormalities. By monitoring the cough intensity in real time, detecting cough abnormalities, realizing early warning and treatment, and improving the accuracy and reliability of cough abnormality detection.

[0045] Further, this grading recommendation method can provide more accurate and targeted warnings for the wearer according to the degree of cough intensity abnormalities, which helps the wearer to take appropriate measures to protect their own health.

[0046] Further, by comparing the new real-time cough intensity fluctuation difference with the preset cough intensity fluctuation difference, the effect of treatment can be evaluated in real time, which provides a basis for whether the wearer needs further examination and treatment, and helps to continuously monitor and evaluate the cough condition, discover changes in the disease condition in a timely manner, prevent the disease condition from worsening, and improve the targeting and effectiveness of treatment.

[0056] Please refer to Fig. 1, which is a flow chart of the wearing type cough monitoring method according to the embodiment of the present application;

[0057] Specifically, the wearing type cough monitoring method provided by the embodiment of the present application comprises,

[0058] Step S1, collecting a physiological signal data set of a wearer;

[0059] The physiological signal data set comprises real-time respiratory frequency, real-time heart rate and real-time cough audio information;

[0060] Step S2, determining whether the real-time respiratory frequency or the real-time heart rate in the physiological signal data set has an abnormal parameter according to a pre-set normal physiological parameter range, and determining the real-time cough audio information in the physiological signal data set corresponding to the abnormal parameter;

[0061] Step S3, analyzing the cough audio information according to pre-set standard information to determine whether to give a warning to the wearer, wherein,

[0062] By comparing the real-time cough frequency in the cough audio information with a pre-set cough frequency, it is determined whether a warning for treatment is needed;

[0063] By calculating the difference between the real-time cough intensity in the cough audio information and a pre-set cough intensity, the real-time cough intensity fluctuation difference is obtained, and by comparing the real-time cough intensity fluctuation difference with a pre-set cough intensity fluctuation difference, it is determined whether a warning for treatment is needed.

[0064] Specifically, the real-time respiratory frequency and real-time heart rate during coughing are determined by the preset normal respiratory frequency range and the preset normal heart rate range to determine whether the body is abnormal, and the cough audio is analyzed in the abnormal case to determine whether the wearer needs to be warned for treatment.

[0065] Specifically, by monitoring the physiological signal data of the wearer in real time, including real-time respiratory frequency, real-time heart rate and real-time cough audio information, the body abnormality can be detected early, and by analyzing the physiological signal data, it can be determined whether the body is abnormal, and the cough audio is analyzed in the abnormal case to determine whether the wearer needs to be warned for treatment, which helps to improve the accuracy and real-time of cough monitoring, reduce the possibility of misdiagnosis and missed diagnosis, and quickly warn and treat the wearer when coughing abnormally, without specific treatment when normal, realizing the effective use of medical resources and avoiding unnecessary medical intervention.

[0066] Specifically, in the step S1, the real-time respiratory frequency of the wearer is collected by the respiratory frequency collection unit, the real-time heart rate of the wearer is collected by the real-time heart rate collection unit, and the real-time cough audio information of the wearer is obtained by the real-time audio collection unit.

[0067] The real-time cough audio information includes real-time cough frequency and real-time cough intensity value.

[0068] Specifically, the respiratory frequency collection unit can be various types of respiratory sensors to monitor and record the number of breaths per unit time, the real-time heart rate collection unit can be various types of heart rate sensors to monitor and record the number of heartbeats per unit time, and the real-time audio collection unit records the cough audio during coughing and analyzes to obtain the real-time cough frequency and real-time cough intensity value during coughing.

[0069] Specifically, by simultaneously collecting multiple physiological indicators of the wearer through multiple collection units, the health status of the wearer is comprehensively monitored, and the accuracy and comprehensiveness of the monitoring are improved. The real-time monitoring of respiratory frequency and heart rate can reflect the overall physiological state of the wearer, and the collection of cough audio information can specifically evaluate the severity of coughing. Multi-dimensional data collection helps better analyze the coughing condition of the wearer.

[0070] Specifically, in the step S2, a preset normal physiological parameter range is set, the real-time respiratory frequency and the real-time heart rate are compared with the corresponding normal range in the preset normal physiological parameter range by the data analysis module, if the real-time physiological parameter in the physiological signal data set does not fall within the corresponding normal range, it is determined that it is abnormal, and the corresponding real-time physiological parameter is marked as the abnormal parameter.

[0071] The preset normal physiological parameter range includes a preset normal respiratory frequency range and a preset normal heart rate range.

[0072] In the specific implementation process, the preset normal respiratory frequency range is 12-20 times per minute, when the real-time respiratory frequency acquisition unit records that the real-time respiratory frequency is 25 times per minute, the data analysis module determines that there is an abnormality at this time, and marks this real-time respiratory frequency as an abnormal parameter, and the preset normal heart rate range is 60-100 times, when the real-time heart rate acquisition unit records that the real-time heart rate is 120 times, the data analysis module determines that there is an abnormality at this time, and marks this real-time heart rate as an abnormal parameter.

[0073] Specifically, by taking the preset normal physiological parameter range as a reference standard, the collected real-time physiological data is preliminarily screened, and possible abnormal conditions are quickly identified, which can effectively further analyze the abnormality, improve the accuracy and efficiency of monitoring, and at the same time, by marking the abnormal parameter, a clear direction is provided for subsequent in-depth analysis and treatment.

[0074] Please continue to refer to FIG. 2, which is a warning determination logic diagram when the abnormal parameter is real-time respiratory frequency in the embodiment of the application;

[0075] Specifically, in the step S3, if the abnormal parameter is real-time respiratory frequency, the real-time cough frequency in the real-time cough audio information is compared with the preset cough frequency;

[0076] If the real-time cough frequency is higher than the preset cough frequency, the spectral characteristics of the cough audio are further analyzed;

[0077] If the real-time cough frequency is not higher than the preset cough frequency, further analysis is not needed.

[0078] In the specific implementation process, the preset cough frequency is 4 times per hour, when the real-time respiratory frequency is an abnormal parameter, if the real-time cough frequency is higher than 4 times per hour, the spectral characteristics of the cough audio are further analyzed, and if the real-time cough frequency is not higher than 4 times per hour, no further analysis is performed.

[0079] Specifically, by analyzing the cough frequency for the case of abnormal respiratory frequency, the health status of the wearer is further evaluated, and this multi-level analysis method can more comprehensively understand the health status of the wearer, avoid misjudgment caused by a single indicator, and at the same time, by setting the preset cough frequency as a threshold, the situation that needs further attention can be effectively screened, and the efficiency and accuracy of monitoring are improved.

[0080] Specifically, in the step S1, an audio analysis unit is further provided, and if the real-time cough frequency is higher than the preset cough frequency, the audio analysis unit is used to obtain the spectrum characteristics of the cough audio, including the peak frequency and the peak amplitude. In the step S3, a preset normal cough spectrum characteristic is further provided, and the actual cough spectrum characteristic is compared with the preset normal cough spectrum characteristic to determine whether there is an abnormal spectrum characteristic.

[0081] If the abnormal spectrum characteristic exists, a warning is sent to the wearer for treatment.

[0082] If the abnormal spectrum characteristic does not exist, a breathing frequency deviation coefficient is calculated according to the maximum value of the preset normal breathing frequency range and the real-time breathing frequency value, and the preset cough frequency value is corrected according to the breathing frequency deviation coefficient to obtain a corrected preset cough frequency value as a subsequent evaluation standard.

[0083] Wherein, K=F1 / F2, K is the breathing frequency deviation coefficient, F1 is the maximum value of the preset normal breathing frequency range, F2 is the real-time breathing frequency value, V2=V1 / K, V1 is the preset cough frequency value, and V2 is the corrected preset cough frequency value.

[0084] Specifically, when the real-time cough frequency is higher than the preset cough frequency, the audio analysis unit obtains the real-time peak frequency P and the real-time peak amplitude H through spectrum analysis of the real-time cough, and obtains the preset normal peak frequency P0 and the normal peak amplitude H0. When P≤P0 and T≤T0, it is determined that there is no abnormal spectrum characteristic, otherwise it is determined that there is an abnormal spectrum characteristic.

[0085] If there is no abnormal spectrum characteristic, in a specific implementation, the normal breathing frequency range is 12-20 times per minute, the maximum value of the normal breathing frequency range F1=20, the real-time breathing frequency value F2=25, the breathing frequency deviation coefficient K=F1 / F2=0.8, the preset cough frequency value V1=4 is corrected to obtain the corrected preset cough frequency value V2=V1 / K=5, and the corrected preset cough frequency value is used as the subsequent evaluation standard.

[0086] Specifically, by monitoring the cough frequency and the breathing frequency in real time, the spectrum characteristics of the cough audio are obtained through the audio analysis unit and compared with the preset normal cough spectrum characteristic to determine whether there is an abnormal spectrum characteristic, which improves the accuracy of cough feature recognition. When the cough spectrum is normal, the preset cough frequency value is corrected according to the breathing frequency deviation coefficient, so that the evaluation standard can be dynamically adjusted according to the real-time breathing condition of the wearer, which is helpful for personalized monitoring of the wearer.

[0087] Specifically, the modified preset cough frequency is used as a new evaluation standard to evaluate the subsequent real-time cough frequency and obtain a subsequent evaluation result. If the subsequent evaluation result still shows an abnormality, a warning is sent to the wearer for treatment.

[0088] Specifically, the modified preset cough frequency is used as a new evaluation standard to evaluate the subsequent real-time cough frequency and obtain a subsequent evaluation result. If the subsequent evaluation result still shows an abnormality, a warning is sent to the wearer for treatment.

[0089] Specifically, the modified preset cough frequency is used as a new evaluation standard to evaluate the subsequent real-time cough frequency and obtain a subsequent evaluation result. If the subsequent evaluation result still shows an abnormality, a warning is sent to the wearer for treatment.

[0090] Please continue to refer to FIG. 3, which is a warning judgment logic diagram of the embodiment of the present application when the abnormal parameter is real-time heart rate;

[0091] Specifically, in the step S3, the preset cough intensity value and the preset cough intensity fluctuation difference are set. If the abnormal parameter is the real-time heart rate, the real-time cough intensity value is calculated with the preset cough intensity value, the real-time cough intensity fluctuation difference is obtained, and the real-time cough intensity fluctuation difference is compared with the preset cough intensity fluctuation difference.

[0092] If the real-time cough intensity fluctuation difference is less than or equal to the preset cough intensity fluctuation difference, no warning is needed.

[0093] If the real-time cough intensity fluctuation difference is greater than the preset cough intensity fluctuation difference, a warning is needed.

[0094] Wherein, ΔIs = I1-I2, ΔIs is the real-time cough intensity fluctuation difference, I1 is the real-time cough intensity value, and I2 is the preset cough intensity value.

[0095] Specifically, the cough sound size represents the cough intensity. In the specific implementation, the preset cough intensity value is I2 = 70, the preset cough intensity fluctuation difference is ΔIs0 = 10, when the real-time cough intensity value is I1 = 75, ΔIs = 5, the real-time cough intensity fluctuation difference is less than the preset cough intensity fluctuation difference, and no warning is needed.

[0096] When the real-time cough intensity value is I1 = 90, ΔIs = 20, the real-time cough intensity fluctuation difference is greater than the preset cough fluctuation difference, and a warning is needed.

[0097] Specifically, by monitoring the cough intensity in real time and comparing it with the preset cough intensity value and the preset cough intensity fluctuation difference, it is determined whether there is an abnormal cough intensity fluctuation difference, thereby realizing early detection and early warning of cough abnormalities. By monitoring the cough intensity in real time, detecting cough abnormalities, realizing early warning and treatment, and improving the accuracy and reliability of cough abnormality detection.

[0098] Specifically, the real-time cough intensity fluctuation difference is compared with the preset cough intensity fluctuation difference. If the real-time cough intensity fluctuation difference is greater than the preset cough intensity fluctuation difference, the real-time cough intensity value is calculated based on the preset cough intensity value to obtain a cough intensity deviation coefficient. Different warnings are given based on the size of the cough deviation coefficient.

[0099] Wherein, K = I2 / I1, wherein K is the cough intensity deviation coefficient.

[0100] Specifically, in specific implementation, different warnings are given according to the size of the cough intensity deviation coefficient. If k ≥ 0.8, the wearer is warned to take simple personal conditioning. If K < 0.8, the wearer is warned to take professional examination and timely treatment.

[0101] Specifically, this grading suggestion method can provide more accurate and targeted warnings for the wearer according to the degree of cough intensity abnormality, which helps the wearer to take appropriate measures to protect their own health.

[0102] Specifically, after warning the wearer, the cough condition of the wearer is continuously monitored to obtain subsequent real-time cough intensity values. The subsequent real-time cough intensity values are calculated based on the preset cough intensity value to obtain a new real-time cough intensity fluctuation difference. The new real-time cough intensity fluctuation difference is compared with the preset cough intensity fluctuation difference.

[0103] If the new real-time cough intensity fluctuation difference is still greater than the preset cough intensity fluctuation difference, it is warned that the treatment is ineffective, and the wearer needs to be further examined and treated.

[0104] Specifically, after warning the wearer, the subsequent monitoring of the wearer's new real-time cough intensity fluctuation difference is less than the preset cough fluctuation difference, and the real-time cough intensity fluctuation difference continues to decrease, which indicates that the treatment is effective.

[0105] Specifically, by comparing the new real-time cough intensity fluctuation difference with the preset cough intensity fluctuation difference, the effect of the treatment can be evaluated in real time, which provides a basis for whether the wearer needs further examination and treatment. Continuous monitoring and evaluation of the cough condition helps to discover changes in the disease condition in a timely manner, prevent the disease from worsening, and improve the effectiveness of the treatment.
