Description

  The present invention relates to a bedding that can comfortably maintain a prone posture for a long time, and a prone position assist mat, an eye mask, and a prone position pillow that can be suitably used with the bedding.

  Humans belong to vertebrates, were born as fish around 500 million years ago, have evolved from fish to amphibians, to reptiles and mammals. During this time, organisms have something in common. That is, the spine is horizontal to gravity, the back is heaven, and the belly is ground. The position of the back changed from the original monkeys, the common ancestors of humans and monkeys, and the chimpanzee started walking with two legs approximately 5 million years ago. It became almost vertical, and the abdomen and spine became front-rear. In the long evolutionary history of vertebrates, organs are best when they are under the spine. Similarly, human organs are in their best state when prone.

  Conventional bedclothes are one flat bedclothes represented by a futon and a bed mattress. Even if it is folded in three or four, it is functionally considered as a single bedding. If it becomes a prone posture on this, a face must be turned 90 degree | times so that a nose may not be supported, and it will become an unnatural posture. In addition, a hard bedding has a small contact area between the bedding and the face, increases pressure, and is painful. For this reason, a prone posture for a long time becomes difficult. Also, even if the entire bedding is soft, the face is turned 90 degrees sideways so that the nose is not supported in the prone posture, and the posture becomes unnatural. In addition, the bedding that is soft as a whole sinks both the body and face, has a large contact area, and thus has a low body pressure, but is difficult to change its position and does not breathe easily.

  On the other hand, it has been found that the prone posture is effective in improving many diseases. Recent prone therapy studies have shown that respiratory, cardiovascular, gastrointestinal, urological, and other dementia and pressure ulcer prevention effects are also effective.

  However, compared to Europe and the United States, there are very few people sleeping in the prone position in Japan, and according to a recent sleep attitude survey, it is said that less than 10% of people sleep in the prone position when falling asleep.

  It is very difficult to sleep for a long time in a prone posture, especially for people with weak physical bodies, stiff elderly people, and those who have slept up for a long time or sideways. As described above, the normal bedclothes are one flat bedclothes typified by a futon and a bed mattress, and the face is placed so that the nose can not be supported in the prone posture. If you do not turn it sideways, you cannot breathe. Various methods for maintaining a prone posture are proposed in "Umune-sleep health method", pages 91-123 (supervised by Shigeaki Hinohara, Midori Kawashima, KK Bestsellers, published on June 2, 2006) Has been. According to this, in order to continue the posture of tilting the face to the left and right, a person with hard neck muscles performs stretching exercise, and depending on the person, a part of the body, for example, under the collarbone, lower leg, etc. is laid. Since it is easy to lift from the bedding, it may be necessary to fill the gap between the body and the bedding with props such as pillows and cushions. In addition, pillows and cushions may be required to feel pain depending on the body part.

  As described above, it is generally very difficult to maintain the prone posture. Although prone position therapy has been found to have many advantages in recent studies, prone position therapy is not readily available. This is because the sleeping posture is unfamiliar, so it is difficult to breathe, the neck hurts, and other causes are sleeping. Since the sleeping posture is affected by the bedclothes, a bedclothing for making it easy to become prone has been proposed.

  Japanese Patent Application Laid-Open No. 10-117905 describes a prone bed pillow having a forehead support, a chin support, and a space around the face. Japanese Patent Application Laid-Open No. 2006-334366 describes a prone pillow having a forehead, both cheeks, a plane on which the chin is placed, and an exhaust port. Japanese Patent Application Laid-Open No. 2007-50222 describes a prone pillow that supports three portions of the head, right cheek, and left cheek. Japanese Patent Application Laid-Open No. 2007-125087 describes a prone pillow having a pad for supporting the forehead and both cheeks.

  The pillows described in the above four documents have support portions that support the forehead, cheeks, chin, and the like, all of the support surfaces are small, and the pressure applied to the face is high. In use, lean on a desk, place on a bed or bedding, and support your face. When these pillows are used to be in the prone position, the face is high, while the abdomen and waist are low, so the prone posture is fully stretched, making prolonged prone position difficult. Also, when used on a bed, it lacks stability and security. Also, because the face is fixed, you cannot turn over freely.

  Japanese Patent Laid-Open No. 10-71056 describes a prone cushion in which an oval opening is provided in the face support and an air passage is formed. JP 2004-89697 describes a set of a prone pillow and a prone mattress having a horseshoe-shaped face support. JP 2006-55383 describes a lying bed pillow having a forehead support and a chest support. Japanese Patent Application Laid-Open No. 2008-12217 describes a bedding for lying on the prone having a forehead support and a pedestal for contacting the chest.

  The invention described in the above four documents is a cushion for prone position having both a face support part and a chest support part, and is placed on a bed or a bedclothes and supports the face and chest part in use. . When used on a bed or the like, the use position is quite high, lacking a sense of security and stability, and turning over is difficult. Furthermore, the prone position is drooling and requires measures such as runny nose, but sheets are not always considered.

  Japanese Patent Application Laid-Open No. 2004-351217 describes a cushioning tool and a mattress for prone position having a vent at the bottom and having a facial recess. Japanese Patent Application Laid-Open No. 2006-340942 describes a mattress having a hole for burying a face.

  The above two references disclose mattresses that are placed on a table and vented through the table. The air when breathing flows through a vent hole in the facial recess for embedding the face or a hole for embedding the face. Although it is necessary to take measures against dirt such as drooling and runny nose in the prone position, the use of sheets for preventing dirt necessary for bedding is not considered. When using a face-shaped recess (oval cutout hole) for embedding the face with an antifouling sheet or woven cloth, the flow of air will be insufficient, and the sheet will come into contact with the face. As a result, the nose and mouth are compressed, and the initial function is lost.

Detailed Description of the Invention

Embodiments of the present invention will be described below with reference to the accompanying drawings. In addition, all of attached drawing is a schematic diagram, and the ratio of the dimension of each part is not necessarily the exact size.
[First Embodiment]
[Overview]

FIG. 1A is a plan view showing the bedding according to the first embodiment of the present invention, and FIG. 1B is a cross-sectional view taken along line X1-X1 in FIG. According to 1st Embodiment of this invention, the bedding 10 provided with the 1st part 1 and the 2nd part 2 which have predetermined length L1, L2 is provided. The first portion 1 and the second portion 2 are separate from each other, and the length relationship is L1> L2
And have substantially the same height H1 and width W1. In use, the first portion 1 having the length L1 is arranged on the user's leg side, and the second portion 2 having the length L2 is arranged on the user's head side. Thus, the 1st part 1 and the 2nd part 2 are arrange | positioned along the direction of predetermined length L1, L2. Furthermore, as will be described later, since the first portion 1 and the second portion 2 are separate from each other, they can be arranged separately from each other at a predetermined distance, whereby the first portion 1 and the second portion 2 are separated. A groove D1 (described later) can be formed between the portion 1 and the second portion 2. The 1st part 1 and the 2nd part 2 are the block bodies accommodated in the main bodies 11 and 12 which have the recessed part (code | symbol abbreviation) recessed along the length direction (L1, L2 direction), respectively. A and B are provided. The upper surface of each of the block bodies A and B forms a face contact portion that contacts at least a part of the face of the user in the prone posture, directly or via a sheet or the like. In the present specification, terms indicating directions such as “left and right”, “up”, and “down” refer to the bedclothes placed on the floor or the like at either end in the longitudinal direction unless otherwise specified. Used when viewed from either side. For example, the “upper surface” of the bedclothes is a surface on the side on which the user's body is placed or supported, and the “lower surface” refers to the surface on the side in contact with the floor surface of the bedclothes. Hereinafter, the details of the first embodiment of the present invention will be described together with specific effects.
[Groove formation]

  As described above, since the first portion 1 and the second portion 2 are separate from each other, they can be arranged separately from each other along a predetermined length direction. At this time, the longitudinal end face (hereinafter referred to as “end face”) including the block body A of the first portion 1 and the longitudinal end face (hereinafter referred to as “end face”) including the block body B of the second portion 2 are opposed to each other. It is in the position to do. In this state, between the surface (for example, floor surface) 100 on which the bedclothes 10 are placed and the longitudinal end surfaces of the first portion 1 and the second portion 2, the width of the bedclothes (W1) direction. A single elongate groove D1 extending along the line is formed. The groove D1 extends so as to completely cross the bedclothes in the width direction, and therefore, the upper end and the left and right ends of the groove D1 are open and are in communication with the outside air.

  When the user lies on the bedding 10 in a prone posture, the groove D1 can function as an air passage that smoothens the movement of air when the user breathes. A user in a prone posture can lie face down or diagonally below so that the nose from the mouth fits in the groove D1 (see FIG. 10B, etc.), and the air is in the groove D1. By moving in, you can breathe comfortably. Therefore, the relative position of the first part 1 and the second part 2 or the distance between them is determined so that the nose from the user's mouth is located on the groove D1. The distance between the first portion 1 and the second portion 2 (in other words, the width of the groove D1) does not necessarily have to be constant along the width (W1) direction of the bedclothes 10, and the user can It suffices if a space is provided between the first portion 1 and the second portion 2 so that the nose of the user can be comfortably breathed. However, if the width of the groove D1 is too large, the head is not sufficiently supported and becomes unstable. Accordingly, the width of the groove D1 is preferably about 30 to 60 mm, for example, but is not limited to this depending on the body shape of the user. As described above, according to the bedding 10 of the first embodiment, unlike the conventional bedding, the nose and mouth are not blocked by the bedding even when the user lies in the prone posture, so that breathing can be performed easily. Is called. When the nose fits in the groove D1, it can face directly below. Further, since the groove D1 is a groove that extends across the bedclothes and that is open at the left and right and upper ends, the user does not receive resistance from the upper surface of the bedding, and has a desired angle (vertical, vertically, etc.). If the downward direction is 0 degree, the face direction can be changed to 30 degrees left and right, 45 degrees left and right, etc., and even if the angle of the face is changed in this way, an easy breathing state can be maintained. Furthermore, since changing the angular position of the face is a kind of turning action, the user can comfortably maintain the prone posture without fixing the face position for a long time.

Thus, in 1st Embodiment, since a user's nose is located in the space of the groove | channel D1, the flow of the air of respiration is good, air does not retain and it can breathe naturally. Further, since the face can be tilted to a desired angle in the groove D1, it is possible to maintain a prone posture for a long time without difficulty.
[Hardness and rebound resilience]

As described above, each of the first portion 1 and the second portion 2 includes the main bodies 11 and 12 having recesses that are recessed along the length direction and the block bodies A and B that are accommodated in the recesses. Yes. The upper surfaces of the block bodies A and B form a face contact portion that comes into contact with at least a part of the user's face directly or via a sheet or the like. The hardness of the main bodies 11 and 12 is about the same as that of a normal bedding, for example, if made of urethane, 100N or more is preferable and 100N or more and 250N or less are more preferable. When the hardness of the main bodies 11 and 12 is within this range, sinking of the bedding in portions other than the user's face is suppressed, and therefore it is easy to maintain a correct sleeping posture and to change the posture. The block bodies A and B can have a hardness lower than the hardness of the main bodies 11 and 12, and are preferably made of urethane, for example, less than 100N, and more preferably have a hardness of 40N or more and less than 100N. preferable. Such a low-hardness material has a good feel on the face, which is the most sensitive part of the body, it is soft against the face, and can obtain an appropriate sink, so the contact area between the face and the bedding Increases pressure and reduces pressure, enabling a comfortable prone posture. The block bodies A and B may have a low resilience modulus. For example, since a general urethane foam used for a bedding has a rebound resilience of 30% or more, the rebound resilience of a low rebound material that can be used in the present invention may be less than 30%. Preferably, it is 5 to 20%. Such low resilience material can also distribute the stress of the load and obtain an appropriate sinking, thus increasing the contact area with the face and reducing the pressure, enabling a comfortable prone posture. . The low hardness or low resilience material used for the block bodies A and B is preferably urethane foam, but is not limited thereto. For example, even if a bag-like outer skin made of a soft material such as cloth is filled with air, gel, etc. to form a three-dimensional shape, or a three-dimensional structure made of synthetic rubber, the above hardness or impact resilience Can be used as the block bodies A and B if they have the same hardness or rebound resilience. As a result, a prone posture for a long time can be achieved without resistance. In addition, although the shape of the recessed part of block body A, B and the main bodies 11 and 12 corresponding to this is a substantially rectangular parallelepiped in this embodiment, it is not restricted to this. If the functions of the block bodies A and B intended in the present embodiment can be exhibited, for example, a cylindrical shape or the like may be used.

  The value of hardness shown in the present specification is a value measured by a method specified in JIS K6400-2, and the rebound resilience is a value measured by a method specified in JIS K6400-3. Each of the above test methods relates to the hardness and rebound resilience of urethane foam, but the material used for the bedding of the present invention is not limited to urethane foam. As long as it has a hardness or rebound resilience equivalent to the value shown in the present specification, it may be ester hard cotton, wool cotton, etc. used in general bedding, gel material, water, air, It may be filled with a spring material or the like.

  In the present embodiment, the block bodies A and B are made of a single material, but each of the block bodies A and B may have a multilayer structure made of different materials. You may have an upper layer and a lower layer. In this case, it is preferable that the upper layer has a low hardness of less than 100N or a low rebound resilience of less than 30%, and the lower layer has a hardness of 100N or more and 300N or less. In particular, it is more preferable that the upper layer has a hardness of 40N or more and less than 100N or a rebound resilience of 5% to 20%. This configuration is advantageous particularly when the thickness of the bedding 10 is relatively large, for example, when it is about 80 mm or more. Use soft material or low-resilience material only for the upper layer including the face contact area that requires a soft touch, reduced body pressure, increased contact area, etc., and the lower layer has the same hardness as normal bedclothes If the material which has is used, manufacturing cost can be held down. In addition, for a user who is particularly heavy in weight, the amount of sinking can be controlled by reducing the thickness of the upper layer and making the lower layer harder than the upper layer. Variations can be increased.

  The block body A of the first part 1 is located in the center of the width (W1) direction of the first part 1, and the block body B of the second part 2 is the width (W1) of the second part 2. ) Located in the center of the direction. Thereby, when a user lays on the bedding 10 in the prone position, the face is likely to be naturally positioned on the block bodies A and B.

  In the present embodiment, the concave portion of the first portion 1 has a length direction (direction along the length L1) of 50 to 100 mm, a dimension L3 of 200 to 300 mm, and a height direction of about 50 to 250 mm. A block having a dimension (equal to the height H1 of the bedclothes 10) and having a longitudinal dimension of 50 to 100 mm, a width dimension of 200 to 300 mm, and a height dimension of about 50 to 250 mm in the recess. The body A is joined in a fitted state. The concave portion of the second portion 2 has a length direction (direction along the length L2) of 80 to 300 mm, a width direction dimension W3 of 200 to 300 mm, and a height direction dimension of about 50 to 250 mm (laying bedding 10 And a block body B having a lengthwise dimension of 80 to 300 mm, a widthwise dimension of 200 to 300 mm, and a heightwise dimension of about 50 to 250 mm is fitted in the recess. It is joined in a state. That is, in the first embodiment, the outer dimensions of the block bodies A and B are substantially the same as the corresponding recesses. The plane dimensions (length direction and width direction dimensions) of the block bodies A and B and the corresponding recesses described above are preferable as dimensions that can be widely applied as face contact portions of boys and girls having general body shapes. Usually, the block bodies A and B are formed separately from the corresponding main body 11 of the first part 1 and the main body 12 of the second part 2, respectively, and are fitted and bonded to the recesses. It may be molded integrally with the main body 11 and the main body 12. However, it may be preferable to form separately from the viewpoint of manufacturing cost.

  In use, the block bodies A and B forming the face contact portion are arranged at positions facing each other across the groove D1, but the end surfaces of the block bodies A and B forming the groove D1 are less than 30%. The cut surface of the block body made of a material having a rebound resilience or hardness of less than 100N. In other words, the surface is located at the end of the block body. When the force applied to the central portion of the block body and the force applied to the end portion are the same, the amount of subtraction is greatly different. That is, in order to obtain the same amount of subsidence, a large force is required at the central portion of the block body, but a small force is sufficient at the end of the block body. When the bedding 10 is used, the user's nose and mouth (teeth) are positioned at the end portions (groove forming surfaces) of the block bodies (face contact portions) A and B. At this time, the ends of the block bodies A and B The pressure applied to the part is relatively small compared to the central part in contact with the forehead and chin. However, as described above, since the end portion of the block body sinks even with a small force, the face contact portions of the block bodies A and B are generally recessed along the user's face structure, and the user can comfortably sit on the stomach. Can sleep in the position.

  In addition, about the user's eye part, the contact surface of the block body B is soft, and an eye contacts the block body B diagonally by inclination of a face. Therefore, in the case of a healthy person, even if the eye part contacts the block body B, there is no adverse effect. However, when a person after surgery uses the bedclothes of the present invention, an eye mask described later can be used so that no pressure is applied to the eye portion.

  Prior art facial pillows and chest mats are used to raise the face or chest, and once the body is displaced from the pillow, etc. It is difficult. In the bedclothes for prone position of the present invention, the entire body lies on the first portion 1 and the second portion 2 having substantially the same height H1, and the face and chest are fixed at a higher position than the other portions. There is nothing. The user can be in the prone posture on the plane, the limbs can move freely, and a comfortable and stable prone posture can be obtained.

  The effect of the present invention was confirmed using the following measurement method. Using a body pressure sheet with a length of 1920 mm / 32 sensors and a width of 670 mm / 32 sensors, lying down in a prone position with the face facing down on a conventional hard cotton duvet, and counting the contact points between the upper surface of the duvet and the face The entire face did not contact the upper surface of the futon, and the number of contact points in the posture of contacting from the nose to the lower (chin) was 12, and 15 in the posture of contacting the forehead. The maximum pressure at this time was 100 mm · Hg or higher because the jaw pressure was high, and the forehead pressure was 80 mm · Hg. In this way, it was found that the pressure applied to the face was very high when it was in a prone position with the face facing straight down with a normal hard futon.

On the other hand, using the above-mentioned body pressure sheet and lying on the bedding of the present invention using low-rebound urethane (hardness 50N, density 75kg / m ³ ) for the block body, lay down in the prone position with the face facing down, When the points were counted, there were 22 contact points, and the maximum pressure was 40 mm · Hg of the jaw part. Furthermore, in the case of the conventional stiff cotton duvet, when measured in the prone posture with the face sideways, the number of face contact points was 26 and the maximum pressure was 100 mm · Hg or more, and low-resilience urethane was used. In the bedclothes of the present invention, in the prone posture with the face sideways, the number of face contact points was 31, and the maximum pressure was 30 mm · Hg.

In the first embodiment, the first portion 1 and the second portion 2 are different from each other in the main bodies 11 and 12 and the block body A, in which the face contact portion and other portions have different hardness or rebound resilience. B was provided. However, instead of this, the first portion 1 and the second portion 2 may have uniform hardness or rebound resilience. Even in this case, by forming the groove D1 between the first portion 1 and the second portion 2, a comfortable prone posture can be maintained for a long time without tilting the face by 90 degrees. However, it is preferable that at least the upper surfaces of the first portion 1 and the second portion 2 are a soft material having a hardness of less than 100 N or a low resilience material having a resilience of less than 30%, particularly urethane foam. However, other materials may be used as long as they have the same hardness or rebound resilience. In this case, not only can the pressure be reduced by increasing the contact area with the face, but a function as a bedclothing for preventing pressure ulcers can be imparted.
[Use status]

FIG. 2 shows an example of a state in which the bedding 10 shown in FIG. 1 is actually used. In the example of FIG. 2, the first part 1 and the second part 2 are wrapped in separate skins 1 ′ and 2 ′, and a preferred interval (for example, about 30 to 60 mm) that facilitates breathing between them is provided. A groove D1 serving as an air communication path is formed between the outer skins 1 ′ and 2 ′ and a floor surface (not shown). A plan view, a side view, and an end view at this time are shown in FIGS. 2A, 2B, and 2C, respectively. FIG. 3 is a back view of the bedclothes 10 wrapped in the outer skins 1 ′ and 2 ′ shown in FIG. The outer skins 1 ′ and 2 ′ are bag-like, and the material may be a material for a normal mattress, such as a woven fabric such as cotton woven fabric or wool woven fabric, leather, knitted fabric, quilted fabric, or the like. In this example, a connecting portion 13 using Velcro (registered trademark) or the like is further provided on the left and right end portions of the back surfaces of the first portion 1 and the second portion 2 wrapped in the outer skins 1 ′ and 2 ′. ing. In this way, by connecting the first part 1 and the second part 2 via Velcro (registered trademark) or the like, the relative positions of the first part 1 and the second part 2 are not greatly shifted. And the width of the groove D1 optimum for the user can be maintained. The width of the groove D1 can be changed depending on the connecting position or length of the Velcro (registered trademark) or the like.
[Hygiene measures]

  In the prone posture, the water in the mouth and lungs moves, and is released to the outside as drooling, and the appearance of sputum is improved, so it is said that the lung function is improved. However, on the other hand, bedding for prone position is required to take measures against dirt such as drooling and runny nose.

  As shown in FIGS. 2 and 3, when the first part 1 and the second part 2 are wrapped with separate skins 1 ′ and 2 ′, the first part 1 and the second part 2 are made to be skins that can be cleaned with alcohol. Both the first and second parts 2 can be sanitized by wiping with alcohol or the like. In addition, since the outer skin 1 ′ surrounding the first portion 1 and the outer skin 2 ′ surrounding the second portion 2 are completely separated, the first portion 1 and the second portion are separated from the outer skin 1 ′ and 2 ′. There is no portion that forms a recess where dust accumulates between the portions 2, and it is hygienic.

As an example, by placing a waterproof sheet or towel 14 between the outer skin 1 'and the outer skin 2' as shown in FIGS.

This form is optimal not only for personal use but also for use in hospitals, nursing homes, etc. used by many people.

  Further, as shown in FIG. 5, a waterproof sheet or a towel 14 or the like is inserted into the groove D1 so that both end portions in the length direction cover the upper surface side of the block bodies A and B, and drooling, runny nose, etc. It can also be a measure against dirt.

  Conventional beddings generally use sheets and bedding on the bedding to prevent soiling, but in the bedding 10 of this embodiment, instead of the bag-like outer skins 1 ′ and 2 ′, ordinary sheets are used.・ Can be used. It is possible to use a sheet, a cloth, or the like that is bridged from the first portion 1 to the second portion 2 and inserted into the groove D1.

  Note that it is difficult to use general sheets in the above-mentioned example of JP-A-2004-351217. In this example, unless a sheet having a hole in the contact surface of the face is used, it is difficult to fulfill the original function of the cushion body, which freely distributes outside air and makes the user's breathing easier. If an attempt is made to use a sheet with holes, the cost is high, and an operation for aligning the hole in the cushion body with the hole in the sheet is necessary.

  As described above, the groove D1 formed between the first portion 1 and the second portion 2 (or the outer skin 1 ′ and the outer skin 2 ′) allows smooth movement of air during breathing, In addition to having a function of not blocking the nose, it also has an important function as a place for sandwiching sheets and mattresses for preventing dirt, and for sandwiching towels for drooling and wrinkles.

  Furthermore, the bedclothes 10 for the prone position of the present embodiment are bedclothes that can lie comfortably even when sleeping in the supine position by placing a normal pillow used in the supine position on the second portion 2. is there. In general, the size of a normal pillow used in the supine position is a plane size of 400 mm × 400 mm or more. On the other hand, the dimensions of the upper surface of the block body B formed of a low resilience or soft material (rebound resilience less than 30% or less than 100 N) are width W3 = 200 to 300 mm and length L4 = 80 to 300 mm. Even when a normal pillow used in a supine position is placed and used, the pillow is supported by the main body 12 around the block body B. Therefore, the weight of the head of about 5 kg is dispersed within the plane dimension of the pillow, and the supine posture is maintained without any influence.

  Furthermore, the bedclothes 10 for prone position according to the present embodiment are bedclothes for placing a normal pillow used in the supine position on the second portion 2 and sleeping comfortably even when sleeping in a lying position. As described above, since the planar dimension of a normal pillow is larger than the dimension of the upper surface of the block body B, it is substantially unaffected by low resilience or soft material (rebound resilience less than 30% or hardness less than 100 N). . Further, since the presence of the groove D1 is a small width of about 30 to 60 mm, it does not affect either the supine position or the recumbent position.

In other words, the lying bedding 10 for prone position according to the present embodiment is a novel bedding that can be applied to all sleeping positions in the supine position, the lying position, and the prone position when used in combination with a normal pillow.
[Second Embodiment]
[Overview]

  FIG. 6A is a plan view showing the bedding 20 according to the second embodiment of the present invention, and FIG. 6B is a cross-sectional view taken along line X2-X2 of FIG.

In the bedding 20 of the second embodiment, as in the first embodiment, the first portion 3 and the second portion 4 are recessed portions that are recessed along the length (L1, L2) direction (reference numerals omitted). ) And block bodies A ′ and B ′ accommodated in the recesses. However, in the second embodiment, unlike the first embodiment, the block bodies A ′ in the first and second portions 3 and 4 are different.
, B ′ lengthwise dimensions L5 and L8 are smaller than the recess lengthwise dimensions L3 and L4. In this embodiment, the length direction dimension L5 of the block body A ′ in the first portion 3 is smaller than the length direction dimension L3 of the recess by L6 = 0 to 30 mm, and the length of the block body B ′ in the second portion 4 is longer. The length direction dimension L8 is smaller than the length direction dimension L4 of the recess by L7 = 10 to 60 mm. Thereby, the first portion 3 as a whole (with the block body A ′ joined to the concave portion of the main body 21) forms a concave portion 31 that is depressed in the length direction by about L6 = 0 to 30 mm, The part 4 of 2 forms the recessed part 32 depressed in the length direction by about L7 = 10 to 60 mm as a whole (in a state where the block body B ′ is joined to the recessed part of the main body 22). In use, the first portion 3 and the second portion 4 are arranged along the length (L1, L2) direction so that the recesses 31 and 32 are in positions facing each other. In the second embodiment, the recesses 31 and 32 together with the surface 100 on which the bedding 20 is placed form a groove D2 that makes the user's breathing easier. Hereinafter, the configuration of the second embodiment will be described together with specific effects. However, in the following description, the differences between the first embodiment and the second embodiment will be mainly described, and the other portions will be described in detail. Omitted. The second embodiment is substantially the same as the first embodiment except for the concave portions of the main bodies 21 and 22 and the portions related to the block bodies A ′ and B ′.
[Groove formation]

  In the case of the second embodiment shown in FIGS. 6A and 6B, the first portion 3 and the second portion 4 are not necessarily arranged in a state of being separated from each other. Even if the first portion 3 and the second portion 4 are arranged so close that their longitudinal end surfaces (meaning the end surfaces of the main bodies 21 and 22) are in contact with each other, the recess 31 of the first portion 3 is used. The groove D2 having a width (L6 + L7) = 10 to 90 mm is formed by the length direction dimension L6 = 0 to 30 mm and the length direction dimension L7 = 10 to 60 mm of the concave portion 32 of the second portion 4. When the end face of the first portion 3 and the end face of the second portion 4 are arranged so as to contact each other, the upper end of the groove D2 is open, but the left and right end portions are substantially closed. Is in a state. However, the widths W2 and W3 of the block bodies A 'and B' are about 200 to 300 mm, and the width of the human face is generally about 150 mm. Therefore, the user can breathe comfortably through the space between the face and the groove D2. However, since the first portion 3 and the second portion 4 are separate from each other, the width of the groove D2 can be reduced to L6 + L7 by adjusting the distance between the first portion 3 and the second portion 4 as desired. It may be larger than.

The user lies in the prone position on the bedding 20 with the nose from the mouth positioned in the groove D2. Due to the length of the groove D2 (equal to W2 and W3), even if the user freely changes the angle of the face directly below or diagonally, the nose is blocked and breathing is not hindered. Since the user can breathe easily through the space between the face and the groove D2, it is not necessary to turn the face sideways by 90 degrees, and a prone posture for a long time can be easily maintained. Since the space where the nose is located becomes the groove D2, the flow of breathing air is good, air does not stay, and natural breathing is possible. Furthermore, since changing the angular position of the face is a kind of turning action, the user can maintain the prone posture comfortably without the face position being fixed for a long time.
[Hardness and rebound resilience]

  The hardness of the main bodies 21 and 22 and the hardness or rebound resilience of the block bodies A ′ and B ′ are the same as in the first embodiment. By using such a low hardness or low resilience material for the block bodies A ′ and B ′, the bedding surface (A ′, B ′) in contact with the face is soft against the face and an appropriate amount of sinking Therefore, the contact area with the face is increased, the pressure is reduced, and a comfortable prone posture can be maintained. Moreover, by setting the hardness of the main bodies 21 and 22 to 100 N or more, the sinking of the bedding can be suppressed, the correct sleeping posture can be easily maintained, and the posture can be easily changed.

Since the surface forming the groove D2 is a cut surface of a low resilience or soft material (rebound resilience less than 30% or hardness less than 100N), that is, a surface located at an end of the block body, It sinks with a small pressure. For this reason, even if a nose and a mouth (teeth) are located at the end (groove surface) of the block, it can be easily recessed along the face structure, and the user can spend comfortably.

  In the second embodiment, the first portion 3 and the second portion 4 are respectively composed of the main bodies 21 and 22 and the block body A ′ having different hardness or rebound resilience between the face contact portion and the other portions. The configuration was provided with B ′. However, instead of this, the first portion 3 and the second portion 4 may have uniform hardness or rebound resilience. In this case, as shown in FIGS. 7A and 7B, the first portion 3 and the second portion 4 do not have the block bodies A ′ and B ′, but simply have the recesses 31 and 32. 21 and 22 only. Even in this case, it is possible to form the groove D2 by arranging the main bodies 21 and 22 so that the concave portion 31 and the concave portion 32 are opposed to each other, and the user can face the face 90 degrees sideways even in the prone position. You can breathe easily through the groove D2 without tilting. However, it is preferable that at least the upper surfaces of the first portion 3 and the second portion 4 are a soft material of less than 100 N or a low resilience material having a resilience of less than 30%, particularly urethane foam. In this case, not only can the pressure be reduced by increasing the contact area with the face, but a function as a bedclothing for preventing pressure ulcers can be imparted.

Similarly to the block bodies A and B of the first embodiment, each of the block bodies A ′ and B ′ may have a multilayer structure made of different materials, for example, having an upper layer and a lower layer. Can do.
[Use status]

  As for the bedding 20 of 2nd Embodiment, although the 1st part 3 and the 2nd part 4 may each be inserted in the separate outer skin like 1st Embodiment, FIG. C) As shown in FIG. 9, the first portion 3 and the second portion 4 may be inserted into a series of skins 23 that are partially sewn. For easy understanding, in the plan view of FIG. 8A, the outer shapes of the first portion 3 and the second portion 4 are indicated by broken lines. The outer skin 23 includes bag-like portions 23 a and 23 b connected to each other via a suture line 24. The end portions of the bag-like portions 23a and 23b opposite to the suture line 24 are open before use.

  In use, the first portion 3 and the second portion 4 are inserted into the outer skin 23 from the open ends of the corresponding bag-like portions 23a and 23b, respectively. The lower edge portions of the first portion 3 and the second portion 4 that are opposed to each other in the longitudinal direction (end surfaces of the main bodies 21 and 22) are positioned along the suture line 24. The open ends of the bag-like portions 23a and 23b after the bedclothes 20 are inserted can be closed by bending, sewing, fasteners, or the like.

With the bedding 20 inserted, the upper surfaces of the bag-like portions 23a and 23b of the outer skin 23 fall into the groove D2 at positions corresponding to the recesses 31 and 32, and into the groove D2 between the bag-like portions 23a and 23b. A corresponding space is formed. The user can breathe through this space. A suture line 24 is located on the lower surface of the outer skin 23, and the bag-like portions 23 a and 23 b are connected by the suture line 24. That is, the portions of the boundary portions of the bag-like portions 23a and 23b excluding the suture line 24 can be separated from each other.
[About the length of the first part]

In the first and second embodiments, the first portions 1 and 3 are described as a single member integrated in the length direction, except that the block bodies A and A ′ are formed. However, as shown in FIGS. 10A and 10B, the first portions 1 and 3 may be divided into two in the length direction so as to have the lengths L1a and L1b. 10A and 10B illustrate the case of the bedding 10 of the first embodiment (however, it is wrapped in the outer skins 1 ′ and 2 ′). In this case, connecting members such as strings with Velcro (registered trademark) as described with reference to FIGS. 2 (A) to 2 (C) and FIG. 3 are provided at the left and right ends of the back surface of the two divided parts. May be. The first
The portions 1 and 3 may be divided into three in the length direction so as to have lengths L1e, L1f, and L1g. At this time, in the case of the bedding 20 of the second embodiment shown in FIGS. 6 (A), 6 (B), etc., for example, as shown in FIGS. 12 (A) to 12 (C) and FIG. The divided three portions of the first portion 3 and the second portion 4 may be inserted into a single outer skin 25 made of a ridge-like portion, respectively, to form a bedcloth that can be folded into four as a whole. . In this case, each bag-like portion of the outer skin 25 is connected to each other by a suture line in the same manner as the outer skin 23 described above. These suture lines are indicated by alternate long and short dash lines in FIGS. 12 (A) and 13. A broken line shows the external shape of the bedding 20 inserted in the outer skin 25. In addition, the boundary part of each bag-like part of the outer skin 25 is separable from each other except the suture line part.

Furthermore, as shown in FIG. 11, the length L1 of the first portions 1 and 3 may be set to a length such that the toes are laid out from the user's ankle and out of the bedding 10 and 20. In this case, pressure applied from the ankle to the toe portion is eliminated, and a more comfortable prone posture is possible. At this time, the first portions 1 and 3 are divided into a body portion having a length L1c and a leg portion having a length L1d, and the length L2 of the second portions 2 and 4 and the length L1c of the body portion are determined. The leg length L1d can be changed and adapted to users with different heights. In order to cope with the height difference, several types of leg length L1d may be prepared. In addition, FIG. 11 has shown the case where the said structure is applied to the bedding 10 of 1st Embodiment (envelop | wrapped by outer skin 1 ', 2').
[Third Embodiment]

  According to 3rd Embodiment of this invention, the prone position auxiliary | assistant mat | matte which can be used with the bedding 10, 20 of 1st, 2nd embodiment, or with a normal bedding is provided. In particular, the bedclothes 10 and 20 of the first and second embodiments are effective for maintaining a sufficiently comfortable prone posture by themselves, but are also combined with the prone position assist mat of the third embodiment. Can be used to maintain a more comfortable prone position.

  According to the “Umune Sleep Health Act” (supervised by Shigeaki Hinohara, Midori Kawashima, KK Best Sellers, published on June 2, 2006) It has been proposed to insert props such as cushions.

  It is difficult to judge whether the selected prop is optimal, and the size, thickness, hardness, shape, etc. of pillows and cushions vary, and it is difficult to select the optimal one. In this embodiment, a prone position assist mat suitable for maintaining a generally prone position that is generally ideal is provided.

  The ideal prone posture is said to be a Buddha-like posture in which the angle formed between the thoracic vertebra and the cervical vertebra is about 15 degrees and both shoulders are dropped. With this posture, people can be in the most comfortable sleeping posture.

  14A to 14D show a prone position assist mat 60 according to the present embodiment. (A) is a plan view, (B) is a side view, and (C) and (D) are end views as viewed from the length direction (direction along L9 to L11 in FIG. 14A).

  14A to 14D, the prone position auxiliary mat 60 of the present embodiment is formed of a soft foamed resin body, and has a hardness lower than that of the first portions D and E and the first portion. Or a second portion C having a low rebound resilience. The first part includes a first support part E and a second support part D, and the first support part E is used by the user so as to maintain an angle between the cervical vertebra and the thoracic vertebra of the user in the prone position. The second support portion D is adapted to support the vicinity of the user's clavicle, and the second portion C extends continuously from the second support portion D. Along with the second support part D, the user's chest and abdomen are contacted. In some cases, the mental contact portion F is provided on the first support portion E, which will be described later.

  In the prone position auxiliary mat 60 shown in FIGS. 14A to 14D, the width W4 is set to the average chest horizontal diameter of a person. Since the average chest horizontal diameter of a person is about 290 mm for boys and about 265 mm for girls, about 250 to 330 mm is preferable because it can be widely applied to general men and women. However, the above dimensions are not limited for athletes.

  In order to maintain an ideal angle (about 15 degrees) between the thoracic vertebra and the cervical vertebra, the height (in other words, the thickness) H2 of the second support portion D contacting the vicinity of the user's clavicle is about 40. It is preferable that the height (in other words, the thickness) H4 of the first support portion E that is about ˜100 mm and supports the user's mental portion (chin tip) is about 20 to 60 mm. However, the height H4 of the first support portion E can vary depending on the hardness of the first support portion E. In addition, the height (in other words, the thickness) of the second portion C is preferably equal to the height of the second support portion D. Therefore, in this embodiment, about 40-100 mm is preferable.

  If the second portion C is a urethane foam, it is preferable that the resilience modulus is less than 30% or the hardness is less than 100N. More preferably, it has a rebound resilience of 5% to 20% or a hardness of 40N or more and less than 100N. Thereby, the 2nd part C can be fit so that it may fit softly in a user's chest, and it may act so that the space of a chest may be filled up. The 2nd support part D is located in a user's clavicle vicinity, and has the function to hold | maintain the height of a chest. Accordingly, a foamed resin body having a hardness of about 150N to 500N is preferable. Thus, even if the hardness is relatively high, the bone around the clavicle is thick and strong against pressure.

  The first support portion E can be formed of a foamed resin body of about 150 N to 500 N, like the second support portion D. However, when the hardness of the first support portion E is 200 N or more, some people may feel uncomfortable when the chin portion (chin tip) contacts the first support portion E. In that case, a low rebound urethane having a rebound resilience of less than 30% or a soft material having a hardness of less than 100N is placed on the first support E as the genital contact portion F, and the chin portion (chin tip) is placed on the first support portion E. Even if the 1 support part E is hard, the feeling to a mentality becomes good and can relieve a sense of incongruity. However, the mental contact part F is for improving the feel of the mentalis and is not necessarily required for maintaining the height of the jaw.

  The height (thickness) H3 of the mental contact portion F on which the user's mentalis is placed may be (H2−H4) or less, but is not limited thereto. However, it is preferable to compress and squeeze the tip of the mental contact portion F (the end opposite to the second portion C) in advance so that the chin (tip of the chin) is stably placed ( (See FIGS. 15A to 15C). Even if the mental contact portion F exists, the height of the user's mental shell at the time of use is substantially equal to the height H4 of the first support portion E because the mental contact portion F is made of low-resilience urethane or a soft material. Become.

  The length L11 of the first support portion E that supports the chin is preferably about 30 to 80 mm, but is not limited to this as long as a sufficient area can be secured for placing the chin. The length L10 of the second support part D that maintains the height of the chest near the clavicle is preferably about 50 to 80 mm, and the length L9 of the second part C is the end (opposite side to the first support part E). ) Is just about to exit the user's ribs, and is usually set to about 100 to 300 mm. In addition, the 1st support part E and the 2nd support part D may be formed integrally, and may be separate from each other. In the case of separate bodies, the boundary between the two is not limited to the illustrated position for reasons of manufacturing. For example, the first support portion E may be formed below the second support portion D (see the first support portion E ′ in FIGS. 19 and 20). In this case, the thickness of the second support portion D is changed from H2 to (H2−H4), and the length of the first support portion E is changed from L11 to (L10 + L11).

  If the width W4 of the prone position auxiliary mat 60 is set to about the horizontal diameter of the human chest and the vicinity of the collarbone is maintained at the height of H2 (about 40 to 100 mm), both shoulders fall when sleeping in the prone position, It approaches the ideal prone posture, that is, the posture like the Great Buddha. Furthermore, when the angle between the cervical vertebra and the thoracic vertebra is maintained at about 15 degrees, the ideal prone posture is approached. This is realized as follows.

  In the bedclothes 10 and 20 according to the first or second embodiment, when the face is laid down in parallel with the face facing down (0 degree), the face has a hardness of less than 100 N or a rebound elastic modulus of less than 30%. In this case, the angle between the cervical vertebra and the thoracic vertebra is shallower than the ideal 15 degrees. However, if the prone position auxiliary mat 60 of the third embodiment is used, the position of the chin is held high by the first support portion E. Even if the chin is placed on the chin contact portion F having a hardness of less than 100 N or a rebound resilience of less than 30%, the first support portion E under the chin contact portion F is hard and does not sink (note that the prone position auxiliary mat 60 Since most of them are located on the main bodies 11 and 21, even if the first support portion E is located on the soft or low-repulsive block bodies A and A ′, it does not sink greatly. Also, on the block bodies A and A ′, the force is distributed depending on the thickness of the material of the prone position auxiliary mat 60, and the pressure is distributed in proportion to the contact area with the block bodies A and A ′. For this reason, the forehead comes into contact with the bedding (block bodies B and B ′) with the position of the chin being high. At this time, since the height of the vicinity of the clavicle is maintained by the second support portion D, the angle between the cervical vertebra and the thoracic vertebra can be set to an ideal 15 degrees or an angle close thereto. The second part C is in contact with the chest below the clavicle and is made of a low-rebound material (rebound resilience less than 30%) or a soft material (less than 100N hardness), so it fills the gap in the chest. Absorb and maintain ideal prone posture.

  Further, when the chin is placed on the first support portion E directly or via the chin contact portion F, it can be in the prone position without pressure on the gums. Therefore, the teeth are not adversely affected by the pressure applied to the gums for a long time. The prone position assist mat 60 of the present embodiment also has an effect of reducing the pressure on the teeth and enabling a long-term comfortable prone position to be maintained.

  In order to explain the effect of the prone position auxiliary mat 60 in particular on the second part C, an example of the prone position in the normal bedding 200 using the conventional prop 50 such as a cushion, a pillow, and a cushion is shown in FIG. This is schematically shown in FIG. Conventionally, when sleeping in a prone posture, the prop 50 may be used in a sleeping posture as shown in FIG. In the example of FIG. 16, the right side of the body is placed in contact with the bedding 200, and the prop 50 is sandwiched on the left side.

  FIG. 17 is a view showing the vicinity of the user's head and chest together with the props 50 from the user's head side in order to further explain the usage state of the props 50 of FIG. 16. In the example of FIG. 17, the cushion 50 and the like are placed under the body on the left side when viewed from the user. In the state shown in the drawing, the user receives pressure from the upper surface of the right bedding 200 when viewed from the user, the upper surface of the left cushion 50 and the like. The body bridges between the left and right contact parts and lacks a sense of stability.

  In a long-time sleep, a person turns over naturally, but when changing the positions of the left and right hands and feet from the state of FIG. 17 and changing the posture to a contrasting posture, the prop 50 is also switched to the left and right. It will be necessary. It is very difficult to perform such posture change in an unconscious state.

Instead of the conventional prop 50, the prone position auxiliary mat 60 of the third embodiment is used, and the sleeping posture similar to that of FIG. 16 (the left arm is placed in a front position away from the torso, and the left leg lifts the body). The second part C sinks due to the body pressure from the chest to the abdomen of the user, while the first parts D and E are the height before use. Thus, the prone position auxiliary mat 60 bites between the body and the bedding 200 like a wedge as a whole. Thereby, compared with the conventional prop 50, a contact area with a body becomes large and body pressure dispersion | distribution is performed. The body does not enter a bridge state as shown in FIG. Thereby, it can be in a comfortable and stable prone posture. This effect does not change even when the prone position auxiliary mat 60 is used in the bedclothes 10 and 20 of the first and second embodiments in which the main bodies 1 and 21 have the same hardness as a normal bedclothes.

  FIG. 18 is a view for explaining a use state of the prone position auxiliary mat 60 of the present embodiment, corresponding to FIG. In FIG. 18, the left side of the body (the right side of FIG. 18) opens widely, and at first glance, it appears unstable, but as shown in FIG. 16, the left arm is in a front position away from the torso and the left leg is It is in a very stable posture because it is bent toward the abdomen to lift the body and supports the body.

  It can also be used in a horizontal prone position (prone position where the chest area is horizontal when viewed from the user's head) instead of the bent limb as shown in FIG. In this case, the gap of the unevenness of the entire chest is filled with the second portion C, and a comfortable prone position assisting device is obtained. Moreover, as described above, it is easy to maintain an ideal prone posture in which the angle between the cervical vertebra and the thoracic vertebra is about 15 degrees and both shoulders are dropped.

  Contrary to FIG. 16, when the right arm is bent away from the torso and the knee of the right leg is bent toward the abdomen, the prone position assist mat 60 does not need to be moved. A stable position and a stable prone posture can be maintained. As described above, the prone position assist mat 60 according to the present embodiment does not need to be replaced (replaced) even when the left and right sides are turned over unlike the prop 50 such as a general cushion. The prone position assist mat 60 according to the present embodiment, which does not need to be replaced every time it is turned over, is particularly useful for people who have contracted muscles or who are weak.

  A healthy person can change the angle of the chest according to the position of the limbs by using only the bedclothes 10 and 20 of the first or second embodiment without using the prone position assist mat 60 of the present embodiment. The angle of the (head) can also be changed, and a comfortable prone posture can be taken. However, by using the prone position assist mat 60 of the present embodiment, the ideal angle between the cervical vertebra and the thoracic vertebra is maintained, and the whole from the chest to the abdomen fits the bedding, so that the posture is more comfortable. Can be taken.

  FIG. 19 shows a further variation of the prone position assist mat 60 shown in FIG. 14, wherein elements that are substantially the same as those shown in FIG. 14 are designated with the same reference numerals. 19A is a plan view, FIG. 19B is a cross-sectional view taken along line Y4-Y4 in FIG. 8A, and FIGS. 19C and 19D are end views seen from the length direction. The prone position assist mat 61 shown in FIG. 19 is mainly different from the second support part D of the prone position assist mat 60 in FIG. 14 in the shape of the second support part D '. As with the prone position assist mat 60, the first support portion E ′ for supporting the user's mental portion and the second support portion D ′ for supporting the vicinity of the user's collarbone are separate from each other. In the prone position auxiliary mat 61, for manufacturing reasons, the first support portion E ′ extends to the lower side of the second support portion D ′. Accordingly, a part of the upper surface of the first support portion E ′ constitutes the chin support surface E1.

  In the prone position auxiliary mat 61 of FIG. 19, the end surface in the length direction of the second support portion D ′ on the first support portion E ′ side (in other words, adjacent to the mental support surface E1 or on the head side of the user). A concave portion G that is recessed in the length direction of the prone position auxiliary mat 61 is formed on the end surface in the length direction). The concave portion G is open on the upper surface of the second support portion D ′, thereby preventing the vicinity of the base of the user's throat in the prone posture from being pressed, A more comfortable prone posture can be maintained for a long time. Accordingly, the recess G is positioned substantially in the center with respect to the width direction of the second support portion D ′, and the vicinity of the base of the user's throat is not substantially in contact with the second support portion D ′. It is preferable to have a depth from the upper surface of the second support portion D ′. Further, for the purpose of dispersion of body pressure, it is preferable that the planar dimension of the recess G is not increased more than necessary so that a desired contact area between the user and the second support portion D ′ can be secured. In the present embodiment, the concave portion G has a notch shape having a substantially V-shaped planar shape, and penetrates the second support portion D ′ in the thickness direction. In addition, in the example of FIG. 19, it does not have the mental contact part F as shown in FIG. As described above, the mental contact portion F is for improving the feel of the mentalis and is not necessarily required for maintaining the height of the jaw. However, the mental contact part F may be provided on the mental support surface E1 of FIG.

  Further, the prone position assist mat of the present invention may have a height that decreases from the center of the chest of the user in the prone position to the left and right and / or from the chest of the user toward the abdomen. . The prone position assist mat 62 shown in FIGS. 20A to 20D has a height that decreases from the center of the chest of the user in the prone position to the left and right and from the user's chest to the abdomen. is doing. 20A is a plan view, FIG. 20B is a cross-sectional view taken along line Y5-Y5 in FIG. 20A, and FIGS. 20C and 20D are end views seen from the length direction. Elements that are substantially the same as those shown in FIG. 19 are denoted by the same reference numerals. In the prone position assisting mat 62 shown in FIG. 20, unlike the prone position assisting mat 61 in FIG. 19, the second support part D ″ and the second part C ′ of the first part are respectively arranged vertically. A plurality of plate-like portions arranged on top of each other. In the example of FIG. 20, the second support portion D "is formed of two plate-like portions D" 1, D "2. The plate-like portions D ″ 1, D ″ 2 have dimensions different from each other in the width direction, and the height of the second support portion D ″ is the center in the width direction of the prone position auxiliary mat 62. On the first support portion E ′ so as to decrease in stages (in other words, from the center of the chest of the user in the prone posture). In addition, the width of the plate-like portion D ″ 2 positioned below the second support portion D ″ is smaller than the width of the first support portion E ′). The second portion C 'is formed of three plate-like portions C'1, C'2, and C'3. The plate-like portions C′1, C′2, and C′3 have dimensions different from each other in the width direction and the length direction, and the height of the second portion C ′ is the prone position assist mat. 62 gradually decreases from the center in the width direction toward both sides (in other words, from the center of the chest of the user in the prone position) in the length direction of the prone position assist mat 62 ( In other words, they are stacked one above the other so as to decrease stepwise (from the user's chest to the abdomen). The plate-like portion D ″ 1, the plate-like portion D ″ 2, and the first support portion E ′ have the same thickness as the plate-like portion C′1, the plate-like portion C′2, and the plate-like portion C′3, respectively. And are joined to the plate-like portion C′1, the plate-like portion C′2, and the plate-like portion C′3 at the end faces in the length direction.

The number of plate-like portions constituting the second support portion D ″ and the second portion C ′ is not particularly limited. By gradually reducing the height of the prone position assist mat 62, the body of the user in the prone position can be fitted by the prone position assist mat, and a natural prone position can be maintained. . The second support portion D ″ and the second portion C ′ may not be formed from plate-like portions that are separate from each other, and have a height that decreases stepwise as described above. A single member may be sufficient. Further, in the above modification, the height of the prone position auxiliary mat 62 is gradually reduced by the plurality of plate-like portions, but the prone position auxiliary mat 62 is continuously decreased at a constant inclination. For example, the whole may have a truncated pyramid shape.
[Fourth Embodiment]

Furthermore, according to the present invention, there is provided an eye mask that protects the eyes, which is suitable when the patient is in the prone position after ophthalmic surgery. In the bedclothes 10 and 20 of the first embodiment and the second embodiment, the contact surfaces of the upper surfaces of the block bodies B and B ′ are soft, and the eye part is in contact with the contact surface obliquely due to the inclination of the face, In the case of a healthy person, there is no adverse effect even if the eye part contacts the block bodies B and B ′. However, when a person after surgery uses the bedclothes of the first and second embodiments, it is useful to use the eye mask of this embodiment so that no pressure is applied to the eyes.

  21A to 21C and FIG. 22 show an eye mask 70 of the fourth embodiment. 21A is a plan view, FIG. 21B is a side view of the eye mask 70 viewed from the lower side (the user's chin side), FIG. 21C is a left and right end view, and FIG. FIG. 22 is a cross-sectional view taken along line Z1-Z1 in FIG. In particular, the eye mask 70 of the present embodiment can be suitably used together with the bedclothes 10 and 20 of the first and second embodiments. The eye mask 70 has a predetermined thickness H5 and is continuously formed from a first space 71 for receiving an eye patch for protecting the user's eyes and a first space for receiving the user's nose. The second space 72 is provided.

  The eye mask 70 can be worn or used from above the user's eye patch. The thickness H5 is sufficient to prevent pressure from being applied to the eye patch when the eye mask 70 is attached or used and the face is placed on the block bodies B and B '. It may be sufficient and may vary depending on the hardness of the material of the eye mask 70 (for example, the low resilience similar to the block bodies B and B ′ or a soft resin having a hardness of less than 100 N), but is generally about 30 mm to 80 mm. As shown in FIG. 22, the thickness H5 can be a three-layer structure, and the upper layer and the lower layer 74 located above and below the central layer 73 and the central layer 73 along the thickness direction have substantially the same hardness. However, the hardness range is set to 60N to 500N (JIS K6400-2). In the three-layer structure, a space 75 is provided in the upper layer and the lower layer 74. This space 75 is for avoiding pressure on a healthy eyeball of a user who is placed in prone position by wearing or using the eye mask 70. As a result, the upper and lower surfaces of the eye mask 70 can be made to be in contact with the face. In the case of the three-layer structure, for example, the eye mask 70 can be manufactured by separately forming the center layer 73, the upper layer, and the lower layer 74 having different external shapes depending on the presence of the space 75 and then bonding them to each other. However, the eye mask 70 may have a single-layer structure having a uniform hardness, for example. The length L12 in the left-right direction is determined so that the face is sufficiently covered in the width direction, and is preferably 250 mm or more and 500 mm or less. The vertical width W5 can be set to about 100 mm to 250 mm.

  However, when the hardness of the upper and lower portions 74 is 60N to 150N, the space 75 may not be formed.

  The position and size of the space 71 may be sufficient to accept the eye of the user's eyepatch, but as shown in FIG. 21A, for example, the length L15 = 100 mm and the width W6 = 80 mm. A space 71 having a planar dimension can be formed at a position of a distance W7 = 45 mm from the upper end of the eye mask 70. The position and dimensions of the space 72 may be sufficient to receive the user's nose. For example, starting from the space 71, the distance L13 = 30 mm from the center in the length direction of the eye mask 70 to the left and right, It can be formed to extend to a position of L14 = 50 mm.

  FIG. 23 schematically shows an example of the wearing state of the eye mask 70, and FIG. 24 shows a state when the user wearing the eye mask 70 lies on the bedding 10 of the first embodiment in the prone position. Shown schematically. As shown in FIG. 23, the post-surgical eye with the eye patch 90 received in the space 71 is protected from contact with the block body B by the thickness H5 of the eye mask 70, as shown in FIG. A nose 91 is received in the space 72, thereby preventing breathing from being blocked by the eye mask 70. Further, the eye mask 70 is positioned with respect to the face so that normal eyes are positioned in the space 75, and fixed to the face (head) with a string 80 or the like with two Velcro tapes (registered trademark) 81 attached. And use.

  However, the string 80 or the like for fixing the eye mask 70 to the face is not necessarily provided. The eye mask 70 can be used by simply placing it on the block bodies B and B 'of the bedclothes 10 and 20 without using fixing means such as the string 80.

  In FIGS. 21A to 23, the space 71 is shown as a substantially square plane shape, but may have other shapes. Further, the shape of the space 72 is not limited to that illustrated. Furthermore, the outer shape of the eye mask 70 may not be the substantially rectangular shape illustrated, but may be another planar shape having a curved portion.

  In the bedclothes 10 and 20 of the first and second embodiments, considering the use of the eye mask 70, the thickness (height) of the second portions 2 and 22 is the thickness of the first portions 1 and 21. It may be made smaller than the height (height). That is, as shown in FIG. 24, the thickness (height) of the second portion may be made smaller than H1 by an amount corresponding to the predetermined thickness H5 of the eye mask 70.

  25 and 26 show a modification of the eye mask 70. FIG. Elements that are substantially identical to those shown in FIG. 21 are designated with the same reference numerals. 25A is a plan view of the eye mask 80, FIG. 25B is a side view of the eye mask 80 viewed from the lower side, FIG. 25C is a left and right end view, and FIG. It is sectional drawing along the Z2-Z2 line of A). The eye mask 80 shown in the modified example of FIGS. 25 and 26 does not have the central layer 73 as shown in FIG. 22, so that the upper layer and the lower layer 74 have a single layer 77 continuously. The space 75 formed and provided in the upper layer and the lower layer 74 is different from the eye mask 70 in that it communicates with each other to form a single space 76 (see particularly FIG. 26).

As described above, the thickness of the eye mask of the present invention is generally about 30 mm to 80 mm so as not to apply pressure to the eye patch. However, while the height for protecting the eyes of the user is necessary, in order to maintain the ideal prone posture by reducing the height of the face, the eye mask is preferably thinner. In the eye mask 70, the center layer 73 provided between the upper layer and the lower layer 74 having the space 75 has an effect of increasing the strength of the eye mask 70. However, the thickness of the eye mask 80 may be reduced by omitting the central layer 73 as shown in FIG. 26 (H6 <H5). In this case, as described above, the upper layer and the lower layer 74 positioned above and below the central layer 73 continuously form a single layer 77, and the space 75 provided in the upper layer and the lower layer 74 is A single space 76 is formed in communication with each other. In order to prevent the block bodies B and B ′ from coming into contact with the eye patch when the face is placed on the block bodies B and B ′ via the eye mask 80, the thickness of the eye mask 80 is usually set to However, in the case of a soft resin having low resilience or hardness of less than 100 N, it is preferably about 60 mm or more. By omitting the central layer 73, the thickness of the eye mask can be made as thin as possible while ensuring the thickness necessary to protect the eye with the eye patch.

In addition, since the space 76 in the eye mask 80 that accepts the user's healthy eyes (in other words, the eyes not wearing the eyepatch) penetrates the eye mask 80 in the thickness direction, the healthy eyes It is possible to completely prevent the possibility of being pressed against the central layer 73.
[Fifth Embodiment]

  Furthermore, according to this invention, the pillow for prone position which supports the face of the user of the prone position which a healthy eye person uses is provided.

  27 and 28 show examples of the prone position pillow according to the present embodiment. FIG. 27A is a plan view of the prone position pillow 300, FIG. 27B is a side view as seen from the lower side (the chin side of the user), FIG. 27C is a left and right end view, and FIG. FIG. 28 is a cross-sectional view taken along line Z3-Z3 in FIG. The prone position pillow 300 of the present embodiment has the same length as a normal pillow (L16 = about 300 mm or more) and a width (W9) of about 150 mm to 300 mm. 1. It can be used on the bedclothes 10 and 20 of the second embodiment. The prone pillow 300 has a pair of holes 302 in at least one support surface 301 that supports the face of the user. In the illustrated example, each hole 302 has a groove shape recessed in the thickness (H7) direction of the pillow 300 for prone position, and is in a position corresponding to both eyes of the user in the prone position. Is formed. In other words, the pair of hole portions 302 are formed on the support surface 301 at a distance corresponding to the distance between the left and right eyes of a general user (or the interpupillary distance). It is possible to prevent the eyes of both eyes of the user in the prone posture from being pressed by the support surface 301. For this purpose, the depth of the hole 302 is preferably set so that the eyes of both eyes of the user in the prone position are not compressed by the bottom of the hole (groove in the example in the figure) 302. (Groove) 302 is determined so as not to contact the bottom portion at all.

  In many of the conventional pillows for prone position, the contact portion between the user's head and the pillow is only on the forehead, but in the prone position pillow 300 of the present embodiment, the pair of holes 302 are independent of each other. The support surface 301 exists between the holes 302. Therefore, since it can come into contact with the skull including around the eyes, the contact area of the head is smaller than the conventional pillow for prone position in which the contact portion between the user's head and the pillow is only on the forehead. Remarkably larger. Thereby, the pressure of the head is dispersed, and the user can hold the prone posture more comfortably for a long time.

  In the above example, the pair of holes 302 is formed only on one support surface 301 of the prone position pillow 300, but is similar to the other support surface (not shown) facing the support surface 301. A pair of holes 302 can be formed. Further, each hole 302 may extend through the prone position pillow 300 in the thickness direction of the prone position pillow 300 from one support surface 301 to the other support surface. The hole 302 as such a through hole can be easily manufactured by punching.

  Furthermore, the prone pillow 300 has a notch 303 that opens downward (on the user's chin side) in FIG. The notch 303 is formed at a position where the user's nose can be received. Accordingly, the nose of the user in the prone posture is not compressed by the pillow 300 for prone position, and therefore the user can directly or diagonally face the face without tilting the face sideways by 90 degrees. You can breathe comfortably while facing. Furthermore, in the example of FIG. 27, the notch 303 is used in a prone posture by a cut surface (the lower surface of the prone position pillow 300 that forms the notch 303 in FIG. 27A). It is formed to have a planar dimension (for example, L17 = L18 = about 100 mm) so that the person's mouth and cheeks are not compressed. Furthermore, as shown in FIG. 27, the prone position pillow 300 does not have a surface for supporting the jaw portion of the user. By not having the support surface of the jaw, the space for breathing can be enlarged and the pressure applied to the user's tooth root can be reduced. Furthermore, if used together with the prone position assist mats 60, 61, 62 of the above embodiment, the chin portion is supported by the first support parts E, E ′ of the prone position assist mat, and the user in prone position The angle between the thoracic vertebra and the cervical vertebra can be maintained at an ideal angle.

  The prone pillow 300 is made of a soft resin having a rebound resilience of less than 30% or a hardness of less than 100 N so as to softly fit the user's head and disperse the pressure with a large contact area. Preferably there is.

  The thickness H7 of the prone pillow 300 (height from the upper surface of the bedding) is preferably set to about 40 mm to 120 mm. Furthermore, as described above, the prone position of the present embodiment is such that the angle between the user's thoracic vertebra and the cervical vertebra is approximated to an optimal value (about 15 degrees) by raising the position of the jaw and prone. The positioning pillow 300 is preferably used in combination with the prone position auxiliary mats 60, 61, 62. By using together with the prone position assist mat 60 or the like, the angle adjustment between the thoracic vertebra and the cervical vertebra due to individual differences in body shape becomes easy. Specifically, the prone position pillow 300 having a plurality of thicknesses is prepared for the prone position auxiliary mat having a predetermined height, so that users of various body types can be accommodated. For example, when the prone position assist mat 60 is used alone for a standard-type boy, the height H2 of the second support D is normally set to about 60 mm, whereas the normal-type boy is prone. When the auxiliary mat 60 and the prone position pillow 300 are used in combination, if the prone position of the prone position pillow 300 is approximately 20 mm and approximately 40 mm, two types of body height can be accommodated. Can do. Further, fine adjustment can be performed by using a towel or the like.

Further, when the prone position pillow 300 and the prone position auxiliary mats 60, 61, 62 are used on the bedding 10, 20, the position of the user's face in the grooves D1, D2 of the bedding 10, 20 is increased. You can breathe more easily. In addition, for the following reasons, it becomes easy to treat waste such as drool that occurs during sleep in the prone posture. As described above, when the prone posture is placed on the bedclothes 10 and 20, the cut surfaces of the block bodies A, A ′, B, and B ′ (in other words, the longitudinal end faces or grooves D1 and D2 of the block bodies). The face contact portions of the block bodies A, A ′, B, and B ′ including the surface) are recessed along the face structure of the user as a whole. At this time, the spaces between the cut surfaces of the block bodies A, A ′, B, and B ′ in the grooves D1 and D2 are almost completely filled with the chin portion from the center of the user's nose. However, when the prone position pillow 300 and the prone position auxiliary mats 60, 61, 62 are placed on the bedclothes 10, 20, the support surface 301 of the prone position pillow 300, the prone position auxiliary mat 60, etc. Due to the first support portions E and E ′, the position of the user's face is slightly raised as a whole, and a space in the horizontal direction between the block bodies A, A ′, B, and B ′ and the face can be provided. Accordingly, even when the user's nose is in the grooves D1 and D2 and is below the upper surface of the bedclothes 10 and 20, the periphery of the mouth and the cheeks are not easily pressed by the bedding, thereby discharging drooling and the like. It becomes easy to be done.

The prone position pillow 300 can also be used on a conventional flat bedding, but since there is no groove for breathing in the conventional flat bedding, in order to secure a space for breathing, It is preferable to increase the height of the prone position pillow 300 and the prone position assist mats 60, 61, 62. On the other hand, if it is used with the bedclothes 10 and 20 of the above-described embodiment, the height of the prone position pillow 300 and the prone position auxiliary mats 60, 61 and 62 can be kept low, and the stable prone position Can maintain posture.

The prone position pillow 300 shown in FIGS. 27 and 28 has a substantially rectangular planar shape, but other planar shapes such as a substantially elliptical planar shape having a curved portion. It may be.
