Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sleep control device and a capsule bed, and more particularly to a dream while sleeping.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Unexamined Patent Publication No. 2000-215, there is known an apparatus for determining a sleep state of a sleeping person without directly attaching a sensor or the like to the sleeping person's body. In this device, the internal pressure fluctuation of the air mat laid under the sleeping person is detected, and the sleeping state of the sleeping person is judged from the waveform. Then, the obtained sleep state data is used to monitor the health condition of the sleeping person, and is intended to be used for care of the sleeping person.

[0003]

As described above, although a device for determining the sleep state of a sleeping person has been disclosed in the related art, nothing is disclosed about controlling a sleeping person's dream. There wasn't.

That is, a person has a dream while sleeping, but it is unknown what kind of dream he has. And, during sleep, when you have an unpleasant dream, you wake up awake, and then,
There is a problem that the person may not be able to sleep and may deteriorate his physical condition the next day. However, no technique has been proposed so far for dream control, and the advent of dream control means has been desired.

The present invention has been made in view of the above points, and an object thereof is to control the dream of a sleeping person.

[0006]

<Summary of the Invention><Outline of the Invention> The present invention is to provide a sleeping person with a stimulus corresponding to a dream desired by the sleeping person.

That is, the inventors of the present application have found out the following matters as a result of research on dreams for many years.

(1) Why do you dream?

Since the brain is not inactive at all during sleep, it is considered that random neural activity is reflected in consciousness and becomes a dream.

(2) When do you dream?

Dreams occur both during non-REM sleep and during REM sleep. However, dreams during non-REM sleep are hard to remember, and dreams during REM sleep are easy to remember. The reason for this is that non-REM sleep is sleep for giving cerebral rest, and therefore the activity of the cerebrum is reduced, while the cerebrum is actively active during REM sleep. It may also be related to the occurrence of a "lambda reaction" during REM sleep. "Lambda reaction" is a potential activity in the visual cortex of the optic nerves in the brain that occurs when you look at something with your eyes. In other words, it is synonymous with the processing of visual information in the brain during REM sleep, and it is thought that this is linked to neural activity in the cerebrum to create a visual image.

(3) Can you control your dreams?

The fact that it is a connection of fragmentary nerve activities of the cerebrum means that if an intentional nerve activity is caused by an external stimulus, there is a high possibility of having a dream related to the stimulus. However, it is difficult to control the content of the dream itself, because whether or not the brain performs the same neural activity by the stimulus is based on the personal experience of the stimulus. For example, for a certain stimulus, Mr. A has a comfortable dream, but Mr. B has an unpleasant dream. However, for an individual, if he / she has a comfortable dream for a certain stimulus, it is highly likely that he / she will have the same comfortable dream if the same stimulus is given again.

(4) How to control your dreams.

It is assumed that a person has a dream for external stimulation.
However, if you continue to sleep as it is, it is unstable because it is a collection of fragmentary information, and it will be forgotten immediately. Waking up in the morning and remembering the last dream I had. Therefore,
In order to recognize the stimulus-related dream, it is necessary to give it a stimulus and wake it up at the stage of dreaming.

From the above items (1) to (4), the present inventors have made it possible to control dreams.

The invention according to claim 4 is the invention according to claim 3, wherein the sleep state of the sleeping person (70) is determined based on the detected physiological amount detected by the physiological amount detecting means (50). While the sleep state determining means (81) is provided, the awakening means (9B) awakens when the sleeping person (70) shifts from the REM sleep state to the non-REM sleep state from the sleep state determined by the sleep state determining means (81). It is configured to generate a stimulus (96).

The invention according to claim 5 is the invention according to claim 3, wherein the awakening means (9B) has a predetermined time after the dream inducing means (9A) generates the dream inducing stimulus (93). Over time, it is configured to generate a wakefulness stimulus (96).

The invention according to claim 6 relates to a capsule bed, and is provided with the sleep control device of the invention according to any one of claims 1 to 5.

That is, in the invention according to claim 1, first, the dream inducing means (9A) sets the dream inducing stimulus (93) before going to bed by the sleeper (70) setting the dream inducing stimulus (93). Is set. When the sleeping person (70) goes to bed, the physiological amount detecting means (50) detects the physiological amount such as the heartbeat of the sleeping person (70).

Thereafter, the dream inducing means (9A) determines the sleeping state of the sleeping person (70) based on the physiological amount detected by the physiological amount detecting means (50). And the above dream induction means (9A)
When the sleeping person (70) is in the REM sleep state, a dream-evoking stimulus (93) that causes a dream is generated, and for example, a sound of waves is generated, and the dream-inducing stimulus (93) is applied to the sleeping person (70). ) To.
As a result of this dream-evoked stimulus (93), the sleeping person (70) will have a dream corresponding to the dream-evoked stimulus (93).

Further, in the invention according to claim 2, the dream-inducing means (9A) previously stores the dream-inducing stimulus (93) corresponding to the dream that the sleeping person (70) sees, and the stored dream is stored.

Then, the microphone (53) converts the pressure fluctuation of the air enclosed in the air mat (51) into an electric signal and outputs it.

As shown in FIG. 1, the controller (8A) includes a sleep state determining means (81), a dream inducing means (9A) and an awakening means (9B).

The sleep state determining means (81) determines the sleep state of the sleeping person (70) based on the detected physiological amount detected by the physiological amount detecting means (50).
The heart rate of 0) is detected based on the output signal of the microphone (53). That is, the output signal of the microphone (53) includes not only the pressure fluctuation caused by the heartbeat of the sleeping person (70) but also the pressure fluctuation caused by the breathing or body movement. Therefore, the sleep state determining means (81) filters the output signal of the microphone (53) using a filter circuit (not shown), and separates only the waveform of the pressure fluctuation caused by the heartbeat of the sleeping person (70). And sleepers based on it (70)
To detect your heart rate.

Further, the sleep state determining means (81) is configured to determine the sleep depth, which is the sleep state of the sleeping person (70), based on the heart rate of the sleeping person (70). That is, there is a correlation between the heart rate of the sleeping person (70) and the sleep depth, and as shown in FIG. 4, the heart rate also decreases as the sleep depth increases. Therefore, the sleep state determination unit (5
5) uses the correlation between the heart rate and the sleep depth to determine the sleep depth of the sleeper (70) from the input heart rate of the sleeper (70).

The dream inducing means (9A) includes a stimulation control means (90) and a stimulation generation means (92). And
The dream inducing means (9A) stores in advance the dream inducing stimulus (93) corresponding to the dream that the sleeping person (70) has, and the sleeping person (70) is stored according to the sleep state determined by the sleep state determining means (81). Is configured to generate the dream-evoked stimulus (93) when in the REM sleep state.

The stimulation control means (90) includes a memory (91) which is a storage means, while the sleep state determination means (81).
The REM sleep state (REM sleep state) is determined from the sleep depth which is the sleep state determined by. That is, as shown in FIG. 4, in the non-REM sleep state (NON-REM sleep state), the sleep depth is deep, the heart rate is small, and the disorder is small, whereas in the REM sleep state, the sleep depth is shallow and the heartbeat is small. There are many numbers and the turbulence is large. Therefore, the stimulation control means (90) determines the REM sleep state based on the sleep depth and outputs an actuation signal to the stimulation generation means (92).

Further, the stimulus control means (90) stores a plurality of dream-evoking stimuli (93) desired by the sleeping person (70) in the memory (91), and evokes dreams according to the setting of the sleeping person (70). An actuation signal for generating a stimulus (93) is output.

Memory (91) of the stimulation control means (90)
Is configured to store a predetermined dream-inducing stimulus (93) from a plurality of dream-inducing stimuli (93) generated by the stimulus generating means (92) in response to an input by a sleeping person (70).

The stimulus generating means (92) is provided with an odor (fragrance), a sound (music, environmental sound, noise, human voice, etc.), light,
It is configured to apply a dream-inducing stimulus (93) such as hot and cold stimulus, vibration, weight, pain sensation or electrical stimulus to the sleeping person (70). That is, the stimulus generation means (92) generates the stimulus desired by the sleeping person (70).

The awakening means (9B) is the awakening control means (9B).
4) and a stimulus generating means (95) are provided so that when a sleeping person (70) awakens from a sleeping state, it remembers the dream he had.

The awakening control means (94) is similar to the stimulation control means (90) of the dream inducing means (9A) in that the REM sleep state (from the sleep depth which is the sleep state determined by the sleep state determining means (81)). REM sleep state) is determined. The awakening control means (94) determines the REM sleep state and the non-REM sleep based on the sleep depth, and when the dream evoked signal generates the dream evoked stimulus (93), the sleeping person (70) is in the REM sleep state. When transitioning to a more non-REM sleep state, stimulus generation means (95)
The operation signal is output to.

The stimulus generation means (95) applies a wakefulness stimulus (96) such as sound, light, vibration or posture change to the sleeping person (70) based on the actuation signal of the wakefulness control means (94). It is configured. In other words, the sleeper (70) is dreaming in the REM sleep state by the dream-evoked stimulus (93), and the wake-up means (9B) is awakened when the sleep state is changed to the non-REM sleep state in order to memorize this dream. It is configured to give a stimulus (96) to the sleeping person (70).

The stimulus generating means (92) is, for example,
It is provided on the headboard (31) of the shield (30) in the capsule bed (10). Although not shown, the stimulus generating means (95) may also be provided on the headboard (31).

-Basic Principle of Dream Control- Therefore, the basic principle of the sleep control device (80) will be described.

A person performs cerebral activity in response to the generated stimulus. When cerebral activity is performed, memories that are empirically linked to it are remembered, and these are connected in the brain to create a dream with a story.

The empirically linked memories here differ from person to person, so a given stimulus does not affect everyone in the same way. For individuals, stimuli and experience are linked, so it is likely that the same stimuli will dream the same. For example, if you have a comfortable dream for a certain stimulus, it is thought that good memory is associated with the stimulus, so if you give the same stimulus, you are likely to have a comfortable dream even if the story is different. .

If the stimulus that brings about a comfortable dream can be found, it is almost impossible to awaken during a nightmare by giving the stimulus during REM sleep.

On the other hand, it is necessary to judge whether or not a certain stimulus has a pleasant dream. The sleeping person is awakened at the stage where the REM sleep shifts to the non-REM sleep based on the physiological information obtained by detecting the physiological amount. Then, the person is likely to remember the dream he had during the last REM sleep.
The desired dream-evoked stimulus can be found by performing this procedure multiple times.

<Operation of Sleep Control Device (80)> Next, the sleep control device (80) in the capsule bed (10) described above.
The operation of will be described.

First, the memory (91) of the stimulation control means (90)

Therefore, the sleeping person (70) has the bed body (2
When sleeping at (0), the physiological amount detecting means (50) becomes
The pressure of the air in the air mat (51) including the fluctuation of the heartbeat (0) is detected by the microphone (53). Then, the sleep state determining means (81) detects the heart rate of the sleeping person (70) based on the output signal of the microphone (53), and determines the sleep depth of the sleeping person (70).

After that, the stimulus control means (90) of the dream inducing means (9A), when the sleeping person (70) is in the REM sleep state from the sleep state determined by the sleep state determining means (81), the stimulus generating means. An actuation signal is output to (92) to generate stimulation (92).
Generates a dream-evoked stimulus (93) that triggers a dream, for example,
The sound of waves is generated and this dream-inducing stimulus (93) is used by the sleeping person (70).
Given to. As a result of this dream-induced stimulus (93), the sleeping person (7
0) will have a dream corresponding to the dream-evoked stimulus (93). For example, a sleeper (70) has a pleasant dream related to the sound of waves.

On the other hand, when the sleeping person (70) shifts from the REM sleep state to the non-REM sleep state after the stimulus generating means (92) applies the dream-inducing stimulus (93) to the sleeping person (70), this shift is awakened. The awakening control means (94) of the means (9B) discriminates from the sleep state determined by the sleep state determination means (81). Then, the wakefulness control means (94) outputs an actuation signal to the stimulus generation means (95), and the stimulus generation means (95) generates a wakefulness stimulus (96) for waking up the sleeping person (70). , Produces a bell sound. Sleeping person (70) by this awakening stimulus (96)
Is more awake than sleeping and remembers a pleasant dream.

As a method of storing a plurality of dream evoking stimuli (93) corresponding to the dream desired by the sleeping person (70) in the memory (91) of the stimulus control device, as described above, the dream evoking means (9A) is used. ) And waking means (9B) to induce and memorize dreams multiple times. As a result, the dream stimulus (93) corresponding to the dream the user likes is selectively stored in the memory (91) of the stimulus control device. After that, the person will set the selected dream-evoked stimulus (93) before going to bed.

<Effects of First Embodiment> As described above, according to the present embodiment, the dream inducing means (9A) is provided and the sleeping person (7
Sleeping person (70) because he tried to induce a dream in (0)
Can dream of his own dreams. As a result, the person
You can avoid unpleasant dreams during sleep and prevent awakening. Therefore, sleep deprivation can be prevented in advance, and the physical condition of the next day can be improved.

Since the awakening means (9B) is provided, the sleeping person (7
0) can awaken. As a result, a person can memorize a comfortable dream, and can realize refreshing awakening.

Further, the awakening means (9B) is a sleeper (7
When 0) shifts from REM sleep state to non-REM sleep state, awakening stimulus (96) is generated, so that a person can surely remember a comfortable dream.

Since the capsule bed (10) is provided with the sleep control device (80), it is possible to generate the dream-inducing stimulus (93) which suits the individual's taste, and to make the sleeping comfortable for each individual. Can be realized.
