Technical Field
The invention relates to the technical field of intelligent monitoring watches, in particular to an intelligent monitoring watch suitable for asthmatic patients and a use method thereof.
Background
Bronchial asthma, abbreviated as asthma, is a common chronic inflammatory disease of the airways, and patients often present with reversible airflow limitation. Epidemiological studies at home and abroad show that the prevalence of asthma has increased year by year in recent years.
During the period of asthma attack, patients often have cough, wheezing, chest distress, shortness of breath and other symptoms, and often repeatedly attack, and have obvious negative effects on the quality of life. Thus, early discovery, early treatment, early prevention are the principles that asthma should always follow. There is much evidence that administration of asthma management of pulmonary function and inflammation can reduce the risk of asthma attacks, as patients often fail to properly perceive exacerbations of asthma symptoms. Common indicators of lung function examination in asthmatic patients are first second expiratory volume FEV1 and maximum expiratory Peak flow Peak ExpiratoryFlow, PEF. The lung function of the patient can be objectively and accurately judged by using the lung function instrument. However, the lung function detection device used in hospitals is expensive and requires professional operation, and cannot meet the requirement of dynamically monitoring the change of the lung function of a patient. PEF refers to the highest flow rate of the patient when exhaling hard, has good correlation with FEV1, and can better reflect the patency of the airway. The PEF can be conveniently and rapidly measured through a simple peak flow rate meter, is an important index for a doctor to judge the severity of the disease of a patient and the treatment effect of the disease, and provides a timely and objective basis for adjusting the medication and analyzing the disease control condition. The global asthma prevention and treatment counseling GINA and the national bronchial asthma prevention and treatment guideline take PEF as important indexes for diagnosing asthma and grading the severity of illness, and the illness state of an asthmatic patient can be graded more accurately by combining the clinical symptoms and the PEF value measured by a peak flow rate meter, and the patient in the attack stage can be better found by combining the record of PEF with the grading evaluation of an asthmatic diary, so that the treatment is carried out early, and the method has positive significance for relieving the illness state of the patient. For patients suffering from acute asthma, the PEF value obtained by the peak flow velocity meter can better reflect the condition control condition of the patients, a simple and easy self-monitoring method is provided for the patients, the patients can find the worsening phenomenon of asthma as soon as possible, and the attacks are prevented.

the correct detection method comprises the following steps: when the device is used for detection, a standing position and a sitting position are adopted, a subject rapidly and deeply sucks one breath to the total lung amount position, the mouth of the subject is rapidly contained in the mouth and is tightly covered by the lips, no air leakage is avoided, and the gas in the lung is immediately exhaled by using the maximum strength and the maximum speed; the whole expiration is finished at one time, the middle part cannot be stopped, the neck keeps a neutral position, and the trachea is prevented from being pressed due to the forward bending and backward tilting of the neck; checking for at least 3 times, if the difference between the measured values of 3 times is too large, paying attention to whether the checking method is correct or not, repeating for a plurality of times, so that the difference between the optimal 3 times is less than 5%, or the difference between the measured values of the optimal 2 times in 3 times is less than 40L/min, and taking the highest value as PEF;
detection time: routine inspection: detecting for 2 times in day and night, and after getting up and before sleeping; checking as required: measuring when the symptom appears in the subject, and measuring before and after the exercise and the environmental factor exposure stimulus respectively; checking before and after administration: PEF was measured before and after inhalation of the quick-acting bronchodilators, and the PEF was monitored for days and weeks using controlled drug to assess airway reversibility and drug efficacy;
detecting the effect of PEF on expiratory airflow limitation:
judging by adopting the percentage of the PEF actual measurement value to the normal predicted value, if the PEF is more than or equal to 80 percent of the predicted value, prompting that the PEF is normal or has no expiratory airflow limitation, and distinguishing that the asthma of the patient is well controlled as a green area; PEF accounts for 60% -80% of the expected value, and indicates that the light-moderate expiratory airflow is limited, and the patient has asthma symptoms, and if the patient has symptoms of nocturnal attack, cough, chest distress, wheezing and limited activity, the medication is regulated according to the situation; PEF accounts for less than 60% of the expected value, and indicates that the expiratory airflow limitation degree is heavy, and the expiratory airflow limitation is red, so that the patient has asthma symptoms at rest and limited activity and needs to take medicine immediately;
detecting the effect of PEF variability on variable expiratory airflow limitation:
daily detection: screening measured PEFs every 24 hours to obtain PEFMAX and PEFMIN, and calculating to obtain a daily variation rate PEF24 hours; if PEF24h is less than 10%, sending 'your disease control is stable' to the patient end; if PEF24h is more than 10%, sending 'your condition is unstable, and suggesting to increase one medicine inhalation'; if PEF24h is more than 20%, sending' your illness state is unstable, suggesting to increase one medicine inhalation, and suggesting to consult doctors;
weekly testing: screening the measured PEFs for 1 week to obtain PEF24hMAX and PEF24hMIN, and calculating to obtain Zhou Bianyi-rate PEF1wk; if PEF1wk is less than 10%, sending 'your disease control is stable, and a doctor can be consulted to adjust the dosage' to a patient end; if PEF1wk is more than 10%, sending a 'maintaining current medication' to a patient end;
monthly detection: screening the measured PEF1wk for 1 month to obtain PEF1wkMAX and PEF1wkMIN, calculating to obtain a month variation rate PEF1mon, and if the PEF1mon is less than 10%, sending a patient xx to be regulated medication to a doctor terminal; if PEF1mon is more than 20%, sending ' unstable illness state ' to a patient end, and consulting with a doctor as soon as possible ';
detecting and reminding functions:
according to the state of illness of patients, adjusting the interval time T of each breath detection amount examination; if the patient respiratory gas quantity is not detected in the T, sending a proposal of measuring the maximum respiratory gas quantity as soon as possible to an intelligent bracelet end and sending the proposal to a mobile terminal of the patient or family members;
respiratory exercise function:
the expected vital capacity is set according to the weight, sex and age of the patient, and the patient can train and punch cards every day according to the expected vital capacity, so that the improvement of the lung function is promoted.
Further, the predicted formula of the PEF value is as follows:
the adult formula is: male: PEFL/min=76.5+20.4×a-0.41×a2+0.002×a3+1.19×h
