本発明は入眠判定装置、さらに詳しくは、脈波に基づい
て安定した眠りの状態に達したかどうかと判定する入眠
判定装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a sleep onset determination device, and more particularly to a sleep onset determination device that determines whether a stable state of sleep has been reached based on pulse waves.
［背景技術］
近年の複雑化した社会の中で、不安、不満、怒り、いら
いらなとの心理的、精神的なストレスが増大しており、
これらのストレスが不眠症等の原因となってきている。[Background technology] In today's increasingly complex society, psychological and mental stress such as anxiety, dissatisfaction, anger, and irritability is increasing.
These stresses have become a cause of insomnia and the like.

り、かえって入眠を阻害するおそれが生じていた。As a way to relieve such stress and facilitate falling asleep, it is possible to give the user a comfortable level of stimulation such as sound stimulation or vibration stimulation, or to adjust the temperature and humidity in the room or bed to a comfortable level. It is known that it is effective to However, conventional sleep aid devices that use sound and vibration, or devices that control the temperature and humidity inside the room or bed, have no means of determining whether the user has reached a stable state of sleep. Therefore, stimuli such as sounds and vibrations to encourage sleep may continue to be applied even after falling asleep, or may stop before falling asleep, which may actually hinder falling asleep. was.

なくなるおそれがあった。In order to solve this problem, the inventor of the present invention first developed a device that determines whether a person has fallen asleep by calculating the variance of the integral value of the pulse wave level. However, when the user's sleep reaches a stable state, the pulse rate decreases, so even though the amplitude increases, the integral value hardly changes, or even becomes small, and as a result, the integral value decreases. If it became a little deep, there was a risk that it would be impossible to determine whether or not someone had fallen asleep.

An object of the present invention is to provide a sleep onset determination device that determines whether a stable state of sleep has been reached by determining the average value of energy for one piece.

したものと判断できることになる。Figure 2 (,) is the pulse waveform during wakefulness or light sleep, f
Figure 52 (b) shows the pulse waveforms during stable sleep, and comparing the two reveals that during stable sleep the amplitude is larger and the period is longer than during wakefulness or light sleep. In other words, it can be seen that the area of the portion surrounded by the pulse wave waveform per pulse wave, in other words, the energy per pulse wave increases. Figure 3 shows the relationship between the depth of sleep at the time of falling asleep and the energy per pulse wave.As sleep deepens and approaches a stable sleep state, the energy per pulse wave gradually decreases. It can be seen that it increases. From the above results, the pulse wave level is sampled at regular intervals to find its integral value, and the integral value is divided by the pulse rate during that time to find the average value of the energy per pulse wave. Comparing the values before and after the average energy values lined up in , if the value gradually increases and exceeds a certain value, it can be determined that a stable sleep state has been reached.

に呼応して制御できるようにしている。The pulse wave sensor 1 is detachably attached to the human body with a band or the like, and for example, a luminescent cord (invisible) is placed on either the fingernail or the abdomen. A light receiving element placed on the opposite side of the light emitting element detects blood flow (pulse wave) and obtains an electrical signal corresponding to the pulse wave. The output of the pulse wave sensor 1 is simultaneously input to an integrating circuit 2 and a counting circuit 3 for counting the pulse rate. The integrating circuit 2 is reset at regular intervals in response to No. 8 (reset), and integrates the pulse wave level for the time from when it is once reset until it is reset again. Further, the counting circuit 3 is reset at regular intervals by the same reset signal as the integrating circuit 2, and counts the pulse rate during the period from once being reset until being reset next time. The integral value of the pulse wave level, which is the output of the integrating circuit 2, and the pulse rate, which is the output of the counting circuit 3, are input to the calculation judgment circuit 4 at the time when the nut signal is input to the integrating circuit 2 and the counting circuit 3. The output value of the integrating circuit 2 is divided by the output value of the counting circuit 3. That is, the energy value per pulse wave is determined by the calculation/judgment circuit 4, and this value is stored as appropriate and compared with previous and subsequent values arranged in chronological order, and when the value gradually increases and exceeds a predetermined value, It is determined that the patient has fallen asleep. The calculation/judgment circuit 4 is provided with an output section 5 so that the device can be appropriately controlled in response to the output of the calculation/judgment circuit 4.

である。Therefore, the energy value per pulse wave is taken out as the output of the calculation/judgment circuit 4, and when the energy value is below a predetermined value, an output corresponding to the energy value is obtained, and when the energy value exceeds the predetermined value, an output is obtained. If the output unit 5 is configured to stop the stimulation, for example, in a sleep onset promoting device that provides sound stimulation or vibration stimulation, the intensity of stimulation and stimulation pattern can be controlled in accordance with the depth of sleep, or the stimulation pattern can be controlled depending on the sleep state. This allows stimulation to be stopped at appropriate timing. In other words, the sleep onset promoting device can be feedback-controlled in accordance with the sleep state of the user, and the sleep onset promoting effect can be further enhanced.

The output unit 5 outputs h! to determine the depth of sleep. This makes it possible to adjust the temperature and humidity inside the room or bed to provide an appropriate environment, and as a result, it is possible to promote falling asleep.
