Description

A system of Sleeping management using a biometric signal at unrestrained status and service etc}

The present invention relates to a remote sleep management service based on unconstrained biosignal measurement technology, and more particularly, to a service subject (inpatients, elderly people, elderly living alone, and elderly patients who are uncomfortable, such as inpatients). The present invention relates to a remote sleep management service system based on unbounded biosignal measurement technology for measuring biosignals and analyzing the measured biosignals to provide information for maintaining / promoting a comfortable sleep.

Life's happiness is so important to a person's life that it is no exaggeration to say that it starts with sleep. Sleep gives a person the most basic time of rest. It is also through sleep that energy is supplied to accumulate stamina. Sleep is the time to replenish the energy a person uses during the day. Sleeping is also the time when the growth hormone is the most secreted growth of children. In our body, the brain is the place that oversees all biological functions for life support.

The brain needs rest to balance proper activity. Most of these breaks occur during sleep.

As such, the importance of sleep is insignificant, but most modern people are not getting enough sleep due to excessive work or study. What is important to sleep is the quality of sleep rather than the amount of sleep. In particular, how deep sleep is very important, modern people are often unable to get a good night's sleep due to stress.

In order to get a good night's sleep, you need to first judge your sleep quality and find ways to cope with it. If you're not feeling good after having slept for a long time, you're really tired of feeling good, or if you think you're sleeping but you're not really having trouble sleeping. In many cases, you do not know. It is a problem that can only be revealed when your sleep status is quantified using objective measuring equipment. Even if this is not the case, the optimal sleep time can be derived by quantifying the quality of sleep. It is necessary to develop simple equipment for determining the quality of sleep, but until now, polysomnography (PSG), which is performed in the sleep examination room of a hospital, is the only objective test.

The sleep stages classified based on the sleep polymorphism test consist of 1, 2, 3, 4 stages and RAM sleep stages. During normal sleep, the average person repeats the sleep stages in the order of 1st, 2nd, 3rd, 4th, 3rd, 2nd, 1st stage, and RAM sleep every 90 minutes.

The sleep state determination is read by a specialist by combining various measurement signals obtained from the sleep polysomnogram when the patient sleeps at night in the hospital. Various types of signals are combined to determine sleep status, sleep apnea, arrhythmia, and rapid eye movement. Sleep quality is judged by how often you wake up during sleep or how many levels 3 and 4 you are in deep sleep.

Signals measured during sleep polymorphism include electroencephalogram (EEG), safety (EOG, Electrooculaogram), electrocardiogram (EMG, Electromyogram), electrocardiogram (ECG, Electrocardiogram), arterial oxygen saturation, respiratory movements in the abdomen and chest, respiratory flow , Snoring, body temperature, body posture, and video recording to determine body torsion.

However, such a conventional sleep test method has a problem of having to sleep in a sleep test room of a hospital because of the use of various specialized devices, and a problem of rising costs.

In addition, since the environment is changed to a laboratory that is not a place to sleep normally, it may show different sleep state characteristics than usual, and thus, there is a disadvantage that accurate sleep state measurement is difficult.

In addition, the measurement device is attached to the head, eyeball, chin, chest, abdomen, etc. of the sleeping person to measure various signals, which causes discomfort and discomfort to the sleeping person, which also shows a different sleeping state than usual. There are also disadvantages that can make diagnosis difficult as a sleep state.

2 is a conceptual diagram illustrating a specific function of the sleep management server of FIG.

Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

1 is a configuration diagram of a "remote sleep management service system based on unrestricted biosignal measurement technology" according to the present invention, the biosignal measuring means 100, the gateway 300 and the sleep management server 200, information receiving system It consists of 400.

Here, the biological signal measuring means 10 measures the heart rate and respiration of the measurement target during sleep of the measurement target, generates a sleep biosignal by measuring the weight of the measurement target, and transmits it to the sleep management server 200 located remotely. It serves to transmit.

The bio-signal measuring means 100 is placed on a bed or a common floor in a bedroom where the measurement subject (user) sleeps for the purpose of practical use of a living close medical device, and does not directly connect the measurement equipment to the measurement subject. In this way, the heart rate, respiration, and activity of the subject can be conveniently measured in a non-contact manner.

The biosignal measuring unit 100 includes a biosignal measuring mat 110 which generates a biosignal by measuring a heartbeat and a respiratory volume of the subject in a non-restrained state when the subject is lying and sleeping. The biological signal measuring mat 110 is provided with a high sensitivity nano pressure sensor for measuring the pressure state to be converted by the user's breathing during sleep.

That is, a high-sensitivity nano-pressure sensor is made like a mat and placed on the bed or the yaw on which the user lies down for sleep, and when the user lies down on the biosignal measurement mat 110, the heart rate and breathing, and the amount of activity (the amount the user moves while sleeping) ) Will be detected.

In addition, the weight sensor 120 is coupled to the bio-signal measurement mat 110 to measure the weight of the user to generate weight information.

In addition, the present invention further provides an environmental sensor 130 to the bio-signal measuring means 100 to obtain the environmental information of the sleeping room that the measurement target sleeps and to transmit it to the bio-signal measuring means 100. It may include.

Next, the communication module 140 converts the biosignal and the weight information acquired from the sensor and the weight sensor 120 and / or the environmental sensor 130 provided in the biosignal measurement mat 110 into the sleep biosignal, respectively. It collects, combines the environmental information with the collected sleep bio-signals, converts them into a data format suitable for communication, and transmits the data remotely. At this time, it is preferable to record the ID information in the area in which the data informing the information of the sleep biosignal and the environmental information is recorded, so that when the remote server checks the information, it is known that the sensor collects the information. The communication module may be implemented as a wired communication or a wireless communication module.

Information acquired during sleep of the user (sleep biosignal and environment information) transmitted from the communication module 140 is transmitted to the sleep management server 200 through the gateway 300, in which the gateway 30 is simply a plurality of It can be recognized as a data interface device that performs a function of connecting data between the sensor and the server.

In order to determine the sleep state, as illustrated in FIG. 2, the error of the received sleep biosignal is corrected, and the heartbeat, respiration, and activity data are extracted from the corrected sleep biosignal through a filtering technique.

Next, after correcting the error of the extracted heart rate, respiration and activity data, the sleep state is determined through heart rate analysis, respiration rate analysis and activity analysis based on the error-corrected heart rate, respiration and activity data. In addition, statistics of sleep time, deep sleep, and section information are possible.

The sleep state determination result information thus determined, that is, sleep quality information is registered in an internal database and provided to the associated information receiving system 400 as necessary. In this case, the information receiving system 400 refers to an information terminal provided by a health consultant who manages the user's health, a medical institution equipped with a doctor / nurse, a fire department, a police station, a family, and the like and receiving information.

In addition, the sleep management server 200 generates sleep environment information for maintaining optimal sleep based on the environment information acquired by the environment sensor 130 and the sleep biosignal, and the information receiving system ( 400).

Such information may be provided by a health consultant or medical staff and provided to the user to help the user get a more comfortable and comfortable sleep. In particular, the provision of sleep environment information may play an important role for the user to obtain optimal sleep.

On the other hand, the sleep management server 200 analyzes the sleep bio-signal as a result of the emergency, and generates emergency information to the associated information receiving system 400, for example, fire station or police station, hospital to notify it, from the emergency Ensure follow-up is quick.

This is the case of patients with disabilities, elderly people, senior citizens living alone, etc. requires constant probation. In this case, the use of a separate protection personnel is a waste of manpower and economic waste. However, when applying the unrestricted remote sleep management system such as the present invention, no manpower for monitoring and probation is required, and the emergency situation can be recognized through the analysis of sleep information automatically, so that follow-up actions can be promptly taken. Will be.
