Abstract

To prevent a user from becoming obstructive sleep apnea syndrome by having the lingual radix of the tongue hanging down in the respiratory tract.SOLUTION: In the lower layer of a head receiving part 2 which is a part receiving the head in a pillow, from a center part to a rear of the pillow receiving the rear head part 23 of the head, a pressure receiving part 3 made of hard plastic foam of low foam plastic is attached, the repulsive power is increased between the rear head part 23 and the parietal region rear part 30, the part from the rear head to the parietal region rear part 30 is lifted up, the tongue 32 is lifted up with the hyoid bone 14 by the principle of a lever, and the lingual radix 25 is lifted up and prevented from sinking down in the respiratory tract.SELECTED DRAWING: Figure 1

Description

The present invention is a closed sleep apnea symptom group in which respiration is stopped multiple times for a certain period of time by obstructing sleep, obesity, the elderly, lingual muscle aging, etc. This relates to a pillow that prevents

The main treatment for obstructive sleep apnea syndrome is to start with a nose or nose and mouth fixed with a resin mask with a band and pumped air continuously sent from the nasal cavity to keep the airway positive. There are means to correct closure by nasal continuous positive pressure breathing therapy (CPAP) and a mouthpiece that pushes the lower jaw forward using the upper jaw teeth. (Hereafter, nasal continuous positive pressure breathing therapy is called CPAP)

In the case of a mouthpiece, when the lower teeth 17 are laid with the upper teeth 18 as a support, the tongue base 25 of the tongue 32 is pulled up to prevent it from sinking into the airways 13 by pulling it outward.
However, since the tongue 32 is fixed to the hyoid bone 14 at the lower portion, the pulling force is killed by the hyoid jaw bone 15 no matter how much the upper hyoid jaw bone 15 is pulled up, and the tongue base 25 cannot be pulled up efficiently.
It is difficult to fall asleep with the mouthpiece protruding the mandible 15 in the mouth. For this reason, treatment at medical institutions is limited to patients with mild obstructive sleep apnea syndrome, but this is not actively recommended for treatment. (See Figure 6)

Both must be used as long as they are alive, and in the case of CPAP, there is a feeling of abdominal bloating by injecting pressurized air. Airways and mouths dry out with the pressurized air that was sent in. It becomes easy to get infected with dryness in the respiratory tract and mouth. The skin is rubbed by rubbing the mask because it tightens tightly so that air does not leak. It is hard to fall asleep with the sound of the pump. Since the pump and the mask are connected by a rigid air blowing port, it is difficult to roll over, so you will want to hurt your back.

And if you pay 30% of the insurance burden rate, you have to pay the CPAP equipment rental fee to the hospital, and it is 6000 yen per month.
Both are physically painful, so many people cannot use it even when necessary.

There is such a pillow that prevents the tongue base from hanging down on the airway due to gravity because the airway lays down instead of under the tongue base when lying on the bed as this improvement measure, but sleeping sideways all night is not There are problems such as being difficult and unconscious and supine, so that the effect of lying down is difficult to sustain.

In addition, Patent Document 1 Actual Registration 3155517 is divided into two parts: a part that supports a cervical vertebra part and a occipital part, which is a part close to the shoulder of the pillow, and bisects the front part and the rear part. The cervical vertebra support part is made of a soft material from the head support part, and the cervical support part sinks from the occipital support part.

Since the back part of the pillow that receives the back of the head is made of a hard material, it will not sink until the head is effectively held, and it is difficult to hold the head firmly on the pillow. Is relaxed and the muscles on the front side of the neck are stretched, so that the chin 31 cannot be raised with the occipital region 23 as a fulcrum and the tongue base 25 cannot sink continuously, and the tongue base 25 sinks into the airway 13 and has no lasting effect. It was.

Sleep Apnea Syndrome (SAS) overview and treatment brochure, Treatment of Sleep Apnea Syndrome, Teijin Pharma Limited

People who are born with a small skeleton, obese people, and elderly people often have a narrow space in the airway 13, and when such a person sleeps on his back, the muscles relax during sleep, so the tongue base of the relaxed tongue 32 The present invention is such that 25 is suspended in the airway 13 under the tongue by gravity, and the present invention prevents the tongue base 25 of the tongue 32 from hanging down in the airway 13 and improves severe closed sleep apnea syndrome. Or provide a pillow that can be used lying down. (Hereafter, obstructive sleep apnea syndrome is expressed as OSAS)

Hereinafter, in the case of expressing the direction, it is marked assuming that the figure that is supine upward is viewed from the right side.
Hereinafter, the portion of the pillow that contacts the shoulder of the human body is referred to as the front side (front), and the opposite side is referred to as the rear side (rear).

The left and right movements of the head of the human body are made possible by the first cervical vertebra 19 rotating on the second cervical vertebra. The front and rear movements of the head are that the occipital bone 21 moves back and forth on the first cervical vertebra 19. Is possible.

Hereinafter, the portion of the occipital bone 21 that protrudes most to the opposite side of the face is referred to as the occipital region 23.
Hereinafter, a region around an intersection where the left and right parietal bones 28 and the occipital bone 21 are trifurcated is denoted as a posterior parietal region 30 (see FIG. 11).

In the present invention, relative to the head receiving portion 2 only in the lower layer (lower side) of the rising surface 38 from the central portion of the pillow 1, which is the portion that receives the back head 30 from the back head 23 of the head receiving portion 2 of the pillow 1. By providing a hard load receiving portion 3 in the lower layer of the head receiving portion 2, the load on the head is not distributed to the bedding, but the front side of the pillow receiving the neck 29 (cervical vertebra) from the back head 23 is Since the load receiving portion 3 does not exist in the lower layer, it is easy to sink. Therefore, when it is hung from the back head 23 to the neck 29, a force is generated to sink in the clockwise direction with the back head 23 as a fulcrum. When applied to the back 30, a force is generated to lift the back of the head 30 in the clockwise direction with the back head 23 as a fulcrum, and the tongue fixed to the hyoid jaw 15 by rotating the hyoid jaw 15 in the clockwise direction (arrow A 34 direction). 32 is clockwise with the hyoid 14 as a fulcrum. To rotate tongue base 25 of the tongue 32 is lifted by the lever principle, hardly sag airway 13, to prevent OSAS,

In the treatment of mild OSAS, a medical institution sometimes prescribes a mouthpiece as a therapeutic instrument. The mouthpiece uses the upper teeth 18 to move the lower teeth 17 forward, and the hyoid bone 15 is moved forward (outward of the mouth). When the tongue 32 is laid on the back, the effect of pulling up the tongue 32 is expected. However, the tongue 32 is fixed to the hyoid bone 14 even if the hyoid jaw bone 15 is pulled up. It was difficult to pull up to 32. For this reason, the tongue base 25 of a severely ill person could not be prevented from sinking into the airway 13.

In the present invention, the head receiving portion 2 of the pillow 1 is a highly foamed flexible urethane foam having a small impact resilience, a low local pressure, a low body pressure distribution, a good feel, and flexibility, cushioning and restorability. By forming with a certain low-resilience urethane foam or low-resilience silicone foam, the load on the head is dispersed and absorbed by the bedding under the pillow, but from the center of the pillow to the rising surface 38 on the rear side, the back of the head 23 In order to prevent the load from being distributed to the bedding through the flexible head receiving part 2 due to the weight of the head 30 after the top of the parietal part, the rising surface from the central part of the head receiving part 2 of the pillow 1 that receives the back 30 from the back of the head 23 Low foam plastic, wood (cork, paulownia wood, balsa wood, etc.), foam rubber, rubber, rubber-like resin under 38 or under 38, even when a certain external force with a large rebound resilience is applied. From, etc. Comprising a load receiving part 3 to prevent the dispersion of the load that, by increasing the repulsive and restoring force of the upper portion of the head receiving portion 2 of the part with the load receiving part 3,

With the first cervical vertebra 19 as a fulcrum, the back of the head 30 from the occipital region 23 is lifted clockwise (in the direction of arrow A34), and the hyoid bone 15 is rotated in the direction of arrow A34, which is the neck 29 direction, with the hyoid bone 14 as a fulcrum. Moves to the right from the vertical line 36 directly above the hyoid bone 14, and as a result, the tongue 32 fixed to the hyoid bone 14 is lifted in the direction of the arrow A34 which is the neck 29 direction with the hyoid bone 14 as a fulcrum. The tongue base 25 is lifted from the airway 13 by the principle of (see FIG. 4).

Low foam plastics include polystyrene foam, polyurethane foam, polyethylene foam, urethane foam, phenol foam, polypropylene foam and the like.

In order to increase the resilience of the head receiving portion 2 of the portion that receives the back of the head 30 from the back head 23, the load receiving portion 3 that is relatively hard to the head receiving portion 2 and higher in repulsion (hard) than the head receiving portion 2 is Climbing from the center where the back head 23 is located toward the rising surface 38 on the back side of the pillow 1 or climbing in a curve from the center of the pillow receiving the back head 23 toward the rising surface 38 on the back side It is set to be a gradient or a plate shape that is horizontal from the central part of the pillow that receives the occipital region 23 toward the rising surface 38 on the rear side.

Because the pillow 1 is used on the bedding, the bedding is flexible when the pillow 1 having flexibility, cushioning and restoring properties is applied. Since the load (weighting) is accepted and dispersed, the pillow 1 of the portion subjected to the load is easy to sink, but in the case of the present invention, the upper layer is a foam with low resilience that has flexibility, cushioning and restoring properties. Since the load receiving portion 3 is not provided from the occipital region 23 other than the occipital region 23 to the occipital region 30 to the neck 29 having the cervical vertebrae to the shoulder because it is formed of foamed urethane foam or expanded silicone foam, the weight of the head Is absorbed by the bedding through pillow 1

By providing the cavity hole 4 in the portion of the pillow 1 that holds the cervical vertebra, which is the portion without the load receiving portion 3 of the head receiving portion 2 of the pillow 1, By deforming and absorbing the load, the repulsion of the pillow 1 to the cervical spine is reduced, and the jaw 31 is prevented from rising without giving a repulsion more than necessary, thereby preventing stiff shoulders.
And the load receiving part 3 which consists of a hard low-foaming plastic with little high resilience flexibility in the lower layer (lower side) of the pillow 1 which receives the back of the head 30 from the back of the head 23 from the center of the pillow. By having
Since there is no absorption by the bedding under the pillow 1, when the head receiving part 2 receives a burden on the head, the load receiving part 3 receives the head load from the rear head 23 to the rear side of the pillow that receives the rear head 23. About the head receiving part 2 of the upper part of the load receiving part 3, repulsive force becomes stronger than the part which does not have the load receiving part 3, and about the site | part which receives the site | part of the standing surface 38 of the rear side from the center part of a pillow, an upper layer head receiving part Despite being gently held by 2

Since the load receiving portion 3 is disposed between the rising surface 38 on the rear side from the center portion of the pillow, the reaction force of the head receiving portion 2 located on the upper portion of the load receiving portion 3 becomes strong and the head sinks. As a result, a rotational force is generated in the clockwise direction A34 in the back of the head 30 at the back of the head 30 as shown in FIG. 5, and the hyoid jaw bone 15 and the jaw 31 use the first cervical spine 19 as a fulcrum. Rotate and move toward the neck 29 which is the direction of the arrow A34 which is clockwise.

The tongue 32 fixed to the hyoid bone 14 and the hyoid jaw bone 15 is rotated clockwise, so that the tongue 32 is placed on the hyoid bone 14 and the tongue base 32 is lifted by the lever principle 14 by the lever principle. He was no longer depressed by airway 13. The effect was clarified as shown in Table 1 of “All night sleep polygraphy test” at medical institutions.

Table 1 described below is a test result in a medical institution using an AHI index of sleep apnea syndrome and a pillow made of ordinary urethane foam and a pillow of the present invention.
AHI index of 5 or less is normal, 5 to 15 is mild, 15 to 30 is moderate, and 30 or more is severe.
The normal value of the pulse rate is said to be between 60 and 100 times per minute in general adults.

Before conducting an OSAS test in a hospital, it is possible to easily confirm whether the body is likely to become an OSAS, and whether the pillow of the present invention is effective for the person's OSAS.
When the tongue tip 22 is moved up and down in the sitting or standing position with the mouth closed with no force applied, the tongue tip 22 usually moves to the upper teeth 18 or lower teeth 17. It can be confirmed that the upper teeth 18 or the lower teeth 17 are in contact with the front teeth, which are in contact with the front teeth. This is because the tongue 32 is pulled by the hyoid jaw bone 15 and is pulled in the direction of the teeth with the hyoid bone 14 as a fulcrum in the manner of lever because the jaw 31 is lowered. In this normal state, the number of breaths per minute is counted. The average adult respiratory rate is 16 and the upper and lower lips are closed.

Next, when the jaw 31 is raised and the head is tilted backwards, the upper and lower lips are separated <open mouth> when confirmed, and when the tongue tip 22 is moved up and down and left and right, the tongue tip 22 does not touch the front teeth and starts from the front teeth. Touch the hard palate 37 in the back of the throat (see FIG. 9). Count the respiratory rate per minute with the jaw 31 raised. The breath rate and the jaw 31 in the normal state increased. If the breathing rate in the state is the same, it is difficult to get into the OSAS, and if the breathing rate with the rear jaw 31 raised is higher than the breathing rate in the previous normal state, OSAS is possible The body shape in this case, which is a highly probable person, refers to a shape formed by the throat, airway, tongue, palate and the like.

When a person with a high possibility of OSAS having a higher respiration rate than the previous average respiration rate with the jaw 31 raised supine on the pillow of the present invention, the tongue 32 contacts the front teeth and the respiration rate is normal. If it is the same as the breathing rate per minute, the pillow of the present invention has been improved to a shape that is difficult to become OSAS for people who are prone to OSAS. The value of checking whether the pillow is effective for the person is great, and the structure is simple, so the manufacturing cost can be kept low.

If you use a pillow that lowers the back of the head 30 and raises the chin 31 when you lie down (see Figs. 6 and 7), the airway 13 becomes narrower and air inhalation worsens. Breathing speed was increased to compensate for the oxygen with the breathing rate, and the breathing rate was 30 times per minute, but when using the pillow of the present invention, It was confirmed that there was a significant effect on the obstructive sleep apnea syndrome, which was the same 16 times and had no suffocation, and the effects were as shown in Table 2 below. Other than that, my thirst in my mouth disappeared.

When the pillow 1 of the present invention is used, the neck 29 sinks into the pillow 1, and the load on the head is bedding on the load receiving portion 3 only from the center of the pillow that receives the back 30 from the back of the head 23 to the back. Since the load of the neck 29 is distributed to the bedding, the neck 29 sinks to a place where the load of the neck 29 and the repulsive force of the pillow 1 are balanced, but the cavity 4 is unnecessary. When the neck 29 sinks after eliminating the repulsion, the back of the head 30 is lifted in the direction of the arrow A34 by the action of the lever using the occipital head 23 as a fulcrum, and the tongue 22 is not lowered into the back of the throat. In contact with the front teeth,

This is because the tongue is firmly fixed to the hyoid bone 14 at a position close to the tongue base 25, so that the tongue 32 rotates clockwise with the hyoid bone 14 as a fulcrum when the back 30 of the top of the head rotates in the direction of arrow A34. Then, the hyoid jaw bone 15 rotates clockwise over the line 36 and falls in the neck 29 direction. As a result, the tongue 32 fixed to the hyoid bone 14 is pulled up clockwise with the hyoid bone 14 as a fulcrum, as if the tongue As a result, the tongue base 25 was lifted by the lever principle and the airway 13 was not closed by the tongue base 25. (See FIG. 4 and FIG. 5) This prevented OSAS. In addition, the mouth and throat did not dry because the chin was not closed and the lips were closed, so there was no pain in the mouth and throat due to dryness.

Even if the tongue jaw 15 to which the tongue 32 is fixed with the mouthpiece is pulled up, the tongue 32 is fixed by the hyoid bone 14 and killed. Therefore, as shown in FIG. Because it sinks, it is not effective for patients with milder or more severe symptoms. In CPAP therapy, as long as you live, you have to wear a resin mask and go to bed, and the monthly treatment costs were incurred for a lifetime. It is big from the aspect of. If there is a free sample of the pillow of the present invention at the store, the effect of the pillow of the present invention on OSAS can be confirmed by the respiration rate for 1 minute before purchase.
