Description
Technical Field
The invention belongs to the technical field of medical equipment, and relates to a multi-person one-night multi-sleep-guidance monitoring expansion device.
Background
Sleep well all night, the spirit is hundreds of times better. According to statistics, one third of the life time of a person is spent in sleeping, the sleeping is a necessary process in life, is a biological rhythm, has great influence on the body, the psychology, the behaviors and the like of the person, and has an important effect on the human body: supplementing enough energy, enhancing immunity, promoting growth, improving intelligence, and prolonging life. In conclusion, without sleep, the various systems of the body are out of balance and may lead to death in severe cases. Sleep is an important physiological need for humans, and there may be no humans today without sleep. Therefore, healthy sleep is vital to the health of a person.
The sleep is generally divided into objective sleep and subjective sleep, and sometimes people still feel fatigue after getting up the bed the next day even though the people sleep for 7 and 8 hours objectively at night; most of patients in the clinic have little subjective sleep, many of them have insomnia, shallow sleep, early awakening, easy awakening and the like, even some patients do not sleep for a plurality of months, and various sleep and breathing disorders such as apnea, hypopnea and the like can occur in the sleep. With the increasing living pressure of people, people with sleep disorder are increasing and in a youthful trend. What do these people sleep to the end, can they be diagnosed by the monitoring device? Polysomnography (PSG) can reflect real sleep data of a human body overnight. Polysomnography (PSG) is the gold standard for diagnosing snoring (sleep apnea hypopnea syndrome OSAHS). The examination is suitable for the following groups of people: (1) snoring during sleep or with significant sleep apnea; (2) tired or doze in the daytime for unknown reasons; (3) when the children sleep, mouth opening breath or breath sound becomes coarse, and the growth and development of the children are abnormal; (4) patients with significant arrhythmia at night; (5) those with diabetes with poorly controlled blood glucose or insulin resistance; (6) patients with refractory hypertension; (7) nocturnal asthma or gastroesophageal reflux; (8) the sleep disorder is caused, and the sleep quality and other conditions needing to be followed are hopefully to be objectively known. It can record the sleep respiration parameters of brain electricity, electrocardio, myoelectricity, electro-oculogram, chest and abdomen respiration, snore, mouth and nose airflow, heat sensitivity, blood oxygen saturation, body position, etc. when the patient is sleeping. The sleep-in latent period, the number and time of awakening, two sleep phases, the sleep proportion of each period, the awakening time, the total sleep time and the like can be known, so that the insomnia can be correctly evaluated and diagnosed, and the causes of some insomnia, such as brain lesion, depression, sleep respiratory disturbance, abnormal limb movement and the like, can be found. After the data are recorded all night, the OSAHS can be diagnosed after being analyzed by a sleep technician, the sleep quality, the sleep time, the sleep efficiency, the apnea times and the hypoxia degree of the OSAHS can be known, and finally the severity of the OSAHS can be comprehensively judged. The wrong idea of sleep cognition is eliminated, and the sleep quality of the user is objectively evaluated and known.
However, one standard multi-lead sleep monitoring device can only monitor the sleep of one person at night, namely one-to-one monitoring, and the device price is high (24-80 ten thousand per device), thereby seriously restricting the development of sleep monitoring. For this reason, another portable polysomnography equipment with low price (4-10 ten thousand) is produced. When the sleep monitoring and collecting instrument is used for sleep monitoring and collecting, the data collecting instrument needs to be off-line and independently bound on the body of a patient, monitoring data can be taken down from the patient only after the patient wakes up on the next day, and then the data is connected and exported for checking and analyzing. The portable multi-guide sleep monitoring equipment cannot check the sleep real-time state of a patient in an experiment, a doctor can check the sleep state of the patient only by entering a ward, and the risk of 'easily disturbing the patient, disturbing the sleep and causing the failure of sleep monitoring' exists. Although many portable multi-conductive sleep monitoring devices integrate the functions of data transmission such as bluetooth and wireless, the working frequency band of the IEEE 802.11b/g/n standard of such devices is 2.4GHz, and many devices (such as microwave oven, bluetooth device of mobile phone, etc.) in the surrounding environment also work in this frequency band, so that there may be the problems of channel collision of multiple wireless devices and wireless signal crosstalk, which causes the confusion of monitoring data and seriously affects the monitoring accuracy.
A study on sleep is usually performed, and it is necessary to collect sleep data of nearly one hundred people in multiple tests. According to the prior art, two alternatives are available: one device is used for testing one by one every night; and (4) testing multiple devices and multiple persons at the same night. The first scheme is as follows: the sleep monitoring data acquisition is carried out on each patient one by one at different nights by adopting a multi-sleep monitoring device, the monitoring and acquisition time of a light test is at least three months, and the whole test needs to span several months or even one year by combining with other preparation work. Thus, it is difficult to exclude the influence of the external environment (the weather of the day, ambient noise) on the sleep monitoring. The second scheme is as follows: the test is carried out by multiple devices and multiple persons at the same night, the time required by test data acquisition can be a fraction of that of the first scheme, the whole test acquisition period is greatly shortened, especially the same group of tests are completed at the same night, and the influence of the external environment on test monitoring can be effectively eliminated. However, the adoption of a plurality of devices for simultaneously carrying out the test will increase the investment cost of the devices by several times or even tens of times. Meanwhile, different monitoring devices cannot eliminate the influence of the difference of the devices on the monitoring data. At present, only a few hospitals have a plurality of standard sleep examination beds, most hospitals only have 1 standard sleep examination bed, and a plurality of persons need to be subjected to multi-guide sleep monitoring, one multi-guide sleep monitoring device is adopted, sleep data acquisition is carried out one by one at different evenings, so that the period is long, and the influence of the external environment is large.
