Description

((0001) Paragraph number of the original application).
The present invention is an obstructive type in which breathing is stopped multiple times for a certain period of time by the tip of the tongue covered with palatal sails dripping into the airway due to gravity and blocking the airway when lying down and sleeping. It concerns pillows that prevent sleep apnea.

(0002)
The main treatment for obstructive sleep aspiration syndrome (OSAS) is to fix a resin mask on the nose or nose and mouth with a band and continuously pump pressurized air through the nasal passages to create positive airway pressure. There are means to correct nasal continuous positive airway pressure (CPAP) to prevent obstruction of the airway, and to correct the lower jaw teeth with a mouthpiece that utilizes the upper jaw teeth to push the lower jaw forward.

(0003)
In the case of the mouthpiece, the lower teeth of the mandible 15 are pushed out of the mouth with the upper teeth as a support to pull up the tongue tip 25 of the tongue and prevent it from sinking into the airway 13, but using FIG. To explain, since the tongue body 32 is fixed to the hyoid bone 14 at the lower part, no matter how much the upper mandible 15 is pulled up, the tongue body part 32 is fixed to the hyoid bone 14, so the pulling force is the tongue. It is killed by the bone 14, and the tongue tip 25 cannot be pulled up efficiently, and the tongue tip 25 cannot be separated from the airway. Therefore, the medical institution does not actively recommend it for treatment.

(0004)
Both must be used as long as they are alive, and in the case of the above-mentioned "CPAP", there is a feeling of abdominal bloating due to the infusion of pressurized air, which has the following problems as a feeling of use. The pressurized air sent in dries the airways and mouth. Dryness in the respiratory tract and mouth makes it more susceptible to infection. Since it is tightened tightly so that air does not leak, the skin will be irritated by rubbing the mask. The sound of the pump makes it difficult to fall asleep. Since the pump and mask are connected by a hard plastic air blow hose, it is difficult to turn over, which makes my back hurt, and I have to remove and attach the CPAP device every time I go to the toilet in the middle of the night. Was often awakened.

(0005)
And you have to pay the rental fee of the nasal continuous positive airway pressure device "CPAP" to the hospital, which is a big financial burden. If the insurance burden rate is 30%, it is 6000 yen a month. A separate fee is required.
Both of them are physically painful, and there are many people who cannot use them even if they need them because they have the above-mentioned feeling of use.

(0006)
As a remedy for this, lying down causes the airway 13 to lie down instead of under the tip of the tongue, which prevents the tip of the tongue 25 from dripping into the airway 13 due to gravity. It is difficult to sleep and you are lying unconsciously, so there are problems such as the effect of lying down is difficult to maintain.

Patent Document 1 Jitsuto 3155517 divides the pillow into two parts, the part near the shoulder, the part supporting the cervical spine and the back of the head, the front and the back, and the back head support part is harder than the cervical spine support part. It is made of a material, and the cervical spine support part is made of a soft material from the head support part so that the cervical spine support part sinks from the occipital support part. It is a pillow made of hardness. Since the back part of the pillow on the surface receiving the head is made of a hard material, it did not sink until the head was effectively held, and the head was not firmly grasped by the pillow, making it difficult to sleep.
Patent Document 2 Japanese Patent Application No. 5-341989 is a pillow made of a soft synthetic resin foam having two peaks and a recess formed between the peaks, and is formed between the two peaks and the peaks. It is composed of a pillow core material made of a soft synthetic resin foam having a recess, a bag-shaped body filled with a gel-like substance to be installed in the recess, and a bag body wrapping these.
Patent Document 3 In Practical New Design Registration No. 31555517, the base 11 corresponding to the cervical support portion and the tip portion 12 serving as the occipital support portion are used, and the base portion 11 (cervical spine side) is made relatively hard, and the front portion 12 (head portion) is made relatively hard. The pillow is characterized by the fact that the side) is relatively soft and the tip (head side) sinks from the base (cervical spine) when used. It is a pillow that is provided with a notch groove in the left-right direction, and thin plates inclined to the front are formed in a shape adjacent to each other to increase the deformability.

(0011)
Explaining based on FIGS. 4 to 5, people who are born with a small skeleton, obese people, and elderly people often have a narrow airway 13, and when such a person sleeps on his back and sleeps soundly, the tongue body 32 The muscles including the tongue are relaxed, and the tongue tip 25 covered with the palatal sail 6 of the tongue body portion 32 hangs down in the airway 13.

The seven curved cervical vertebrae from the first cervical vertebra 19 to the seventh cervical vertebra 12 of the neck 29 are bulged like the curvature of the cervical vertebra in many of the conventional pillows. Although a part (see FIG. 6) is provided, the curvature of the cervical spine is an anterior curvature in which the center of the cervical spine bends to the anterior side of the face in many people. Some people have a back curve that warps, others do not have a curve called a straight neck,
And even with these symptoms, there are various directions in which the person jumps out of the shoulder (see Fig. 7). The head 30 at the tip of the cervical spine sinks to the pillow 1 to support it, causing it to bend at the 19th part of the first cervical spine, making it difficult to sleep, stiff shoulders, snoring, and obstructive sleep apnea syndrome (hereinafter referred to as OSAS). ), Which is one of the causes.

The degree of curvature of the convex part and the angle of protrusion from the shoulder are different. The degree of curvature does not match the neck part 29 consisting of the cervical vertebrae. When you lie down, the neck 29 is held by the convex part with the shoulder as the fulcrum, and the posture when the face is facing the front and the top of the head is facing the heavens (upward) by sitting on a chair (hereinafter, "head heaven posture"). The head 30 that can move back and forth between the first cervical spine 19 at the tip of the cervical spine and the occipital bone 21 collapses due to the subsidence of the head, etc. The amount of sedimentation on the pillow differs depending on the flexibility of the pillow (difference in repulsive force). It breaks like a broken and crushed hose, and the airway 13 near the first cervical vertebra 19 narrows.

The tongue 25 covered with the palatal sail 6 hangs down into the airway 13 due to gravity in the airway 13 that narrows when lying on a pillow that collapses the "head heaven posture" as described above, and blocks the airway to the nasal cavity 24. The oral cavity 22 between the body 32 and the palate 11 is blocked by the palatal sail 6 except for eating and drinking, so it cannot breathe unless it breathes through the mouth. When the airway to the airway is obstructed, the oral cavity is usually obstructed by the tongue and palatal sail, so when nasal breathing becomes impossible, it becomes OSAS, and the head 30 is posterior to the "head posture". Breathing that the airway breaks and narrows and lacks oxygen when the head 30 remains tilted (the jaw is lowered) or the head 30 is tilted forward (the jaw is lowered) with respect to the "head-height posture". Since it is supplemented by the number of times, the number of breaths increases, the air flow velocity becomes faster because the breath is strongly and long, and when the air is inhaled from the nose, the air is pulled from the oral cavity according to "Bernouy's theorem", so the air flows above and below the palate. The vibration caused by the shaking (waving) of the palate due to the "Kalman vortex" phenomenon is transmitted to the vocal tract and becomes swelling, and when the jaw in Fig. 8 is lowered, the mitral muscle is stretched, or when the jaw is raised, the mitral muscle is The contraction causes tension and stiff shoulders. The present invention provides a pillow in which the head 30 maintains a "head-top posture" even when lying on its back, and the airway 13 is less likely to be obstructed by breaking at the neck 29.

(0015)
The invention of claim 1 is a concealment in the head receiving portion 2 of the pillow 1 from the top surface 36 to the middle of the bottom surface 37 between the substantially center of the long side surface front 10 and the long side surface rear 16 and the long side surface front 10. A block in which a plurality of slits 17 are inserted to form an aggregate of a plurality of independent columnar blocks from the top surface 36 to the middle of the bottom surface 37, and the cutting depth of the hidden slit 17 is changed depending on the head and neck of the pillow. By changing the size of the aggregate, the depth of subsidence of the head 30 and the neck 29 to the pillow is controlled.

(0025)
By inserting a plurality of hidden slits 17 that are cuts from the top surface 36 to the middle of the bottom surface 37 between the substantially central portion of the head support portion 2 and the front 10 of the long side surface, a plurality of independent columnar blocks are assembled to form a head support. It is divided into a plurality of independent blocks from the top surface 36 between the substantially center of the portion 2 and the front 10 of the long side surface to the middle of the bottom surface 37, and the reaction force that was a mass of one pillow is distributed to the number of blocks and When each block of small columns is pressed by the neck 29 whose surface is curved, each block column is pressed in a direction perpendicular to the surface of the curved neck 29, which is not vertical to the pillow, and lateral deformation is also possible. It occurs, and buckling occurs before the original buckling limit load of each block is reached. Due to this lateral deflection, the reaction force (repulsive force) is also dispersed in the lateral direction, so the reaction force becomes smaller and the neck 29, The reaction force to the head was reduced, and the stiff shoulder caused by the pillow 1 was eliminated. (See FIGS. 12 and 10) Further, the hidden slit 17 adjusts the strength of the reaction force by changing the depth depending on the part.

(0026)
The hidden slit 17 is also shallow in the back of the head 23, or the diameter of the independent column is increased to control the sinking, and even though one point such as the trampoline phenomenon is suppressed, the head is affected by the reaction force of the entire pillow. Suppresses the phenomenon of being pushed back, and hides the neck 29 located between the head 30 and the shoulder 33 that has settled on the pillow so that the "head heavenly posture" does not collapse even if the head 30 is affected by the settling. The slit 17 causes the neck 29, which is located between the head 30 and the shoulder 33, to settle to a position (depth) in which the head 30 and the shoulder 33 are in the "head position" according to the shape (curved state) of the user's cervical spine. The head 30 does not settle on the pillow with the convex part as the fulcrum of the neck like a pillow with a part, but the head 30 settles on a substantially flat pillow without the convex part, and the neck 29 depends on the settling depth. Follows and sinks according to the degree of curvature of the user's cervical spine, so that the "head posture" is always maintained, and swelling, stiff shoulders, and OSAS can be reduced or prevented.

In the case of a pillow having a hump (convex portion) that is a bulge that imitates the curvature of the conventional cervical spine based on FIG. When the shoulder 33 sinks to the bedding 38 and the head 30 is placed on the pillow, the neck 29 is then placed on the hump 34, and the head 30 is placed on the portion over the hump 34, bulging and circular. The hump 34 becomes resistant to compression and supports the neck 29, and then, with the hump 34 as a fulcrum, the tip of the neck 29 (the first cervical vertebra 19 at the tip of the seven cervical vertebrae) weighs 7 kg at the tip of the fishing rod (7 kg). (Average weight of an adult male) When the head 30 sinks to the pillow with a force moment of 7 kg + α, the neck 29 is strongly pulled by the pillow, but the hump 34 is circular and difficult to settle, so the neck 29 is the hump 34. The 19th part of the first cervical vertebra is broken and the back of the head 23 is lowered, the jaw is raised and the airway 13 along the cervical vertebra is broken and narrowed. The palatal drop 7 at the tip of the palatal sail 6 abuts on the airway side wall 13b, and the airway is blocked, resulting in OSAS.

In the case of the pillow of the present invention, as can be seen in FIG. 4 when not lying on the pillow, there is no hump, the shoulder 33 first sinks into the bedding, and then the head 30 rests on the pillow 1 and the neck 29 When the shoulder 33 and the back of the head 23 become both branches in contact with the pillow and the head 30 subsides, an aggregate of a plurality of independent columns of columns bends and buckles according to the shape of each part of the neck 29, resulting in head heaven. The neck 29 follows the head 30 and sinks into an aggregate of blocks until the head 30 (rear head 23) sinks while keeping the degree of curvature of the cervical spine in the posture. In this way, since it works to follow the subsidence of the neck to the subsidence of the head, even if the person lies on the pillow, the airway does not break and narrow at the cervical spine, so that swelling and OSAS do not occur.

(0034)
In addition, the current general coping therapy is nasal continuous positive airway pressure (CPAP) via the hospital, the rental fee of the equipment is 20,000 yen a month, but insurance is applied if you receive a medical examination once a month. In the case of a 30% burden, a medical examination fee of 6,000 yen and a medical examination fee of 1,000 yen are required, and the annual medical expenses are 84,000 yen, which is a heavy financial burden, and it is necessary to receive medical treatment during the opening hours of the hospital. Time and transportation costs were also a burden. The burden of the insurance association is 168,000 yen per person per year, and according to the website of Teijin Home Medical Co., Ltd., the number of potential patients is said to be 3 million, and even if 10% of these people are treated with CPAP. The amount borne by the insurance association is enormous.
In the case of the present invention, it can be inexpensive because it only has a slit in the pillow, and in the case of the CPAP device, positive pressure air must be attached to the nose while sleeping on the mouse at the end of a hard hose, while alive. However, since the present invention only changes the pillow, there is no need to remove or attach the hose even in the case of a toilet in the middle of the night, so the quality of sleep improves. The personal burden is 30%, which is 5 million yen per person.

The effect on obstructive sleep apnea syndrome was clarified as shown in Table 1 of "Overnight Sleep Polygraphy Test" at a medical institution. A man in his 60s at a medical institution who compared the AHI index (apnea-hypopnea index) of obstructive sleep apnea syndrome with a pillow made of normal urethane foam and a pillow made of urethane foam of the present invention as follows. It is the inspection result of.

(0036)
The AHI index showed a significant improvement from 41.2 to 16.9.
The average pulse rate / minute improved from 31.3 to 64, which is within the average value.
The maximum pulse rate / minute improved from 255 to 111, which is within the average value. The significant effect of the pillow of the present invention was shown.

(0037)
When using a conventional pillow that lowers the back of the crown and raises the jaw 31, the airway 13 is narrowed by the tip of the tongue 25 and it is not possible to inhale enough air, so it is possible to recognize suffocation and breathe the necessary oxygen. Because it was supplemented with, the breathing speed became faster, and the respiratory rate was 20 times per minute, but when lying down on the pillow of the present invention, it was 16 times, which is the same as the respiratory rate of the "head heaven posture", and there was no suffocation. In addition, it was confirmed that there is a significant effect on obstructive sleep aspiration syndrome.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the drawings referred to below, the same reference numerals indicate similar components.

(0042)
To explain based on FIG. 1, a plurality of hidden slits 17 that are cuts from the top surface 36 to the middle of the bottom surface 37 between the substantially center of the front and rear of the head receiving portion 2 of the pillow 1 and the front 10 of the long side surface are inserted to form columns. The top surface 36 between the substantially center of the head receiving portion 2 and the front 10 of the long side surface is divided into a plurality of independent blocks, and the hidden slit 17 is divided into different depths depending on the part. By changing the size (diameter) of the independent blocks, the reaction force that was a lump is distributed to the number of blocks, so that each of the plurality of columnar blocks hits the neck 29 whose surface is a curved surface, and each block. The pillar is perpendicular to the curved surface of the neck 29, but it is pushed in a direction that is not vertical to the pillow, and lateral deformation also occurs, causing buckling before the original buckling limit load of each block is reached. This lateral deflection causes the reaction force (repulsive force) to be dispersed in the lateral direction as well, so that the reaction force becomes smaller and the neck 29 maintains the "head heavenly posture" in response to the subsidence of the head 30. Made into a form.

(0053)
According to FIG. 1, the columnar independent columns are formed by inserting a plurality of hidden slits 17 which are cuts from the substantially center of the front and rear of the head receiving portion 2 to the front 10 of the long side surface and from the top surface 36 to the middle of the bottom surface 37. The reaction force on the shoulder is dispersed and reduced by forming an aggregate of a plurality of blocks and forming the upper part of the head receiving portion 2 as an aggregate of a plurality of independent columns of columns. The hidden slit 17 adjusts the reaction force to the neck 29 by changing the depth or the diameter of a plurality of independent blocks depending on the part, and prevents the airway 13 from breaking and narrowing at the neck 29.
