Description

The present invention relates to a lateral position assisting device that can reduce a symptom by maintaining a lateral position while allowing a patient to sleep apnea syndrome to naturally turn over during sleep.

  Symptoms of sleep apnea syndrome are sleepiness due to lack of sleep due to severe snoring and respiratory arrest, and daytime sleepiness induces sleep errors during work and sometimes human errors such as traffic accidents.

  The main cause of sleep apnea syndrome is that muscle groups around the throat block the airways (such as tongue depression) when sleeping in the supine position (supposed position). As a main treatment method for the treatment of sleep apnea syndrome, there is a CPAP method in which the nose and mouth are covered with a mask and breathing is performed with high-pressure air. However, there is a sense of incongruity in wearing a mask, and there is a possibility of hurting rhinitis or vocal cords because air is forced to flow. As a method of using a dental appliance (mouthpiece), there are a method of adsorbing the tongue forward (TRD method) and a method of guiding the lower jaw forward (Esmarch method). However, it is necessary to project the tongue and lower jaw greatly forward, which causes considerable stress on the patient. In addition, when the mouthpiece is used for a long time, the meshing becomes worse.

  On the other hand, the cause of sleep apnea syndrome such as tongue depression can be reduced by sleeping in the lateral position (sideways) or prone position (prone). Although this method is not applicable to all people, it is said to be effective for about 30% of people with sleep apnea syndrome.

However, even if you sleep in the supine or prone position, you will not be in the prone or prone position for a long time with an ordinary futon, mattress or bed. Therefore, although a lateral position assist tool or a prone position assist tool is necessary, if the body is fixed with an assist tool having a too strong restraint, stress accumulates and sleep cannot be achieved. Rolling over has the effect of preventing blood flow from becoming worse due to being in the same posture for a long time, becoming congested, causing stiffness, pressure pain, and the like. Healthy people turn over 20 to 40 times a night during sleep. Even if it is a sleep apnea syndrome, a comfortable sleeping state cannot be obtained if a lateral position assist tool or prone position assist tool that cannot be turned over is used.

  In order to prevent sleep apnea syndrome, an auxiliary device for maintaining a sleeping posture of a human body, particularly a lateral position has been proposed.

  Japanese Patent Application Laid-Open No. 2002-360384 discloses a cushion body that is bent in a substantially square shape and is formed in a substantially triangular shape whose cross-sectional shape decreases toward the inside in the bending direction. The user can maintain the lateral position by placing the head and a part of the body on one end of the cushion body. However, this cushion body does not consider the possibility that the user will naturally turn over by himself / herself, and does not consider the posture after turning over.

  Japanese Patent Application Laid-Open No. 2002-58690 discloses a rucksack type pillow that sleeps on the back. Since this pillow is fixed to the user's body with a string, the user is restrained before bedtime and feels high stress from the beginning. In addition, in a state where the body is fixed to the pillow, it is difficult to hit a natural roll over.

Japanese Patent Application Laid-Open No. 2003-52730 discloses an anti-wrinkle device comprising a pillow-type cushion. This wrinkle prevention tool is used by passing a user's arm through a pair of arm passage portions formed on the cushion. Therefore, the user is restrained before bedtime and feels high stress from the beginning. In addition, in a state where the cushion is fixed to the body, it is difficult to hit a natural roll over.

  Japanese Patent Application Laid-Open No. 2005-34418 discloses a triangular prism-shaped backrest bedding used as a pressure ulcer prevention tool for nursing care. However, since the height is set to such an extent that it cannot be turned over, it cannot be turned over naturally in the left-right direction. Even if it can be turned over, the lateral position cannot be maintained after turning over because of the asymmetrical shape in which one side surface is steeper than the other.

  By the way, when a person performs a large rotation operation such as turning over, first, the waist moves. For example, in order to turn over from a supine posture, first, the rotational movement of the waist occurs, and this acts on the upper chest from the abdomen, and when the body rotates about 30 to 45 degrees from the floor, A rotation angle slightly different from the angle can be maintained. The angle of the chest can be consciously or unconsciously different from the angle of the waist, while the angle of the waist changes depending on the angle of the chest, and they interact with each other. When the waist and chest are rotated in the same direction, the angle of the chest can maintain a large angle. For example, by rotating the waist 45 degrees, the chest (shoulder) is also rotated 45 degrees, and then the chest (shoulder) is further rotated 45 degrees from this position, thereby making the chest angle 90 degrees. The portion from the chest to the head can be maintained at a 90-degree posture from the floor.

  As described above, the point of turning over is at the waist, and when turning over, only the chest (shoulder) cannot be rotated. By slightly rotating the waist, the chest (shoulder) can also rotate greatly.

  In order to prevent apnea syndrome and snoring, it is necessary to reduce the obstruction of the upper respiratory tract (throat). Therefore, it is necessary to turn the upper airway sideways to reduce airway obstruction around the uvula. That is, in order to prevent apnea syndrome and snoring, it is particularly necessary and important to turn the head sideways from the chest.

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.

[Overview of lateral position assist device]
FIG. 1 is a perspective view showing the entire lateral position assisting device according to an embodiment of the present invention. FIG. 2 is an end view of both ends in the longitudinal direction of the lateral position assisting tool of FIG. The lateral position assisting tool 1 according to the present embodiment includes a kamaboko-shaped cushion body 2 as shown in FIGS. 1 and 2, the cushion body 2 having a height H of 4 cm or more and 8 cm or less, and The width W is 8 cm or more and 15 cm or less. The lateral position assisting tool 1 is placed on a bedding such as a mattress or a bed mattress, for example, and the user can attach the lateral position assisting tool 1 to any one of the left and right side surfaces 3a, 3b extending in the longitudinal direction of the lateral position assisting tool 1. Use along the spine. In the present specification, terms such as “left and right”, “upper”, “lower” and the like regarding the lateral position assisting tool refer to the lateral position assisting tool disposed on the bedclothing, unless otherwise specified. It is used when viewed from either one of both ends.

[Kamaboko-shaped shape of the lateral position assist tool]
As shown in FIG. 1, the lateral position assisting tool 1 of the present embodiment as a whole has a kamaboko shape, and maintains the above-described constant height H and width W over the entire length L. It extends almost uniformly. In this specification, the “kamaboko shape” means a shape whose cross section in the width direction is a kamaboko shape, specifically, a substantially flat lower surface 4 as shown in FIG. It means a symmetrical shape formed by side surfaces 3a and 3b having substantially the same height extending in a substantially vertical direction and a substantially curved upper surface 5 extending between the upper ends of the side surfaces 3a and 3b.

[About the height of the lateral position assist tool]
In the present embodiment, the cushion body 2 that forms the lateral position assisting tool 1 has a height H of 4 cm or more and 8 cm or less. Thereby, the user can get over the lateral position assisting tool 1 from side to side and lie down consciously or unconsciously during sleep. Such a height H that can be turned over is usually preferably set to about 20 to 25% of the chest width of the user. By setting the height to 4 cm or more and 8 cm or less, the lateral position assisting tool can be widely applied to boys and girls having a general body shape.

[Width of lateral position assist tool]
The cushion body 2 of the present embodiment has a width W of 8 cm to 15 cm. If the width is too small, it will not be stable when placed on bedding. Moreover, even if it tries to ride over the cushion body 2, the upper surface 5 of the cushion body 2 will be crushed and cannot be turned over smoothly. On the other hand, if the width is too large, the body stops while riding on the upper surface 5 of the cushion body 2, and the cushion body 2 cannot be overcome. In general, the width W of the cushion body 2 is preferably set to about one third of the chest width of the user. If it is set to 8 cm or more and 15 cm or less, it can be widely applied to boys and girls having a general body shape.

[Others]
Since the user uses the spine along one of the left and right side surfaces 3a, 3b of the lateral position assisting tool 1, the lateral position assisting tool 1 requires a certain length. The length L is not particularly limited, but the length that can be supported from the vicinity of the thoracic vertebra to the waist or the tailbone in a state where the user lies along the side surface 3a or the side surface 3b can stably maintain the lateral position. Therefore, it is preferable. In this embodiment, it is 50 cm-70 cm, for example.

  The material of the lateral position assisting tool 1 may be a foamed material such as urethane or rubber, or a soft resin material that does not deform so much when leaning. The hardness is preferably about 200 to 600 N in the urethane JIS standard. If the hardness is too high, it will be difficult to roll over and it may cause stiffness and pain on the back when leaning on for a long time. When the hardness is too low, the degree of deformation due to the weight of the user when leaning is large, and a sufficient effect of maintaining the lateral position cannot be obtained, and it is difficult to overturn over the lateral position assisting tool. The hardness can be measured by a method defined in JIS K6400. Specifically, for a 50 × 380 × 380 (mm) test piece, the thickness at the time of 5N load is assumed to be the original thickness, and after compression of 75% of the original thickness, the original thickness is restored and compressed again to 25% of the original thickness. Measure the load after 2 seconds.

  In the lateral position assisting device 1 having the above-described configuration, the user sleeps with the spine along one of the side surfaces 3a and 3b (eg, the side surface 3a) that is substantially perpendicular to the bedclothes, so that the substantially complete scoliosis is obtained. The position (the sleeping posture in which the angle of the waist with respect to the bedclothes is about 90 degrees) can be easily maintained. Furthermore, by having a height H of 4 cm or more and 8 cm or less and a width W of 8 cm or more and 15 cm or less, if the person has a general body shape, the person who gets over the lateral position assisting tool 1 alone will be able to overturn. can do. Rolling over can be made smooth along the curved upper surface 5 of the lateral position assisting tool 1, and even after overturning the lateral position assisting tool 1 by turning over, the spine rests on the vertical side surface 3 b on the side that has been climbed over. Since it is in the state along, it can still maintain the lateral position.

  The lateral position assisting tool 1 is made of a foamed material such as urethane or rubber as described above, or a soft resin material, so that even when the side surfaces 3a and 3b are vertical surfaces, about 30 from the complete lateral position. It is possible to make a small roll over that is inclined about a degree. By enabling both a large rollover and a small rollover in this way, the lateral position can be maintained without giving a strong sense of restraint or stress to the user.

Note that the left and right side surfaces 3a and 3b of the lateral position assisting tool do not need to be completely perpendicular to the lower surface 4 of the lateral position assisting tool. It is only necessary to be substantially perpendicular to the lower surface 4 to such an extent that a substantially complete lateral position can be maintained. Further, the angle may be adjusted by about 10 degrees in consideration of the inclination of the bedclothes when a person lies down. Specifically, as shown in FIG. 3, when a user (not shown) lies along one of the left and right side surfaces 3 a, 3 b of the lateral position assisting tool 1 placed on the bedding 6, the gravity direction When the force F is applied, the bedding 6 sinks and tilts toward the user. Although the magnitude of this inclination varies depending on the softness of the bedding 6, it is normally expected to be about 10 degrees. Due to the inclination of the bedding 6, the lateral position assisting tool 1 also tilts. If this inclination is not corrected, the upper part of the lateral position assisting tool 1 applies pressure to the user's body, and the user feels a sense of pressure. . Therefore, the angle of the side surfaces 3a and 3b of the lateral position assisting tool 1 may be formed so as to be inclined inward by about 10 degrees with respect to the lower surface 4. That is, the angle between the side surfaces 3a and 3b and the lower surface 4 may be between about 80 degrees and 90 degrees. Thereby, when going to bed, a substantially vertical surface is formed with respect to the surface (horizontal plane in FIG. 3) on which the human body is located on the bedding 6. In the present application, the shape in which the side surfaces 3a and 3b have an inclination of about 80 to 90 degrees with respect to the lower surface 4 is also included in the kamaboko shape. Moreover, the upper surface 5 of the kamaboko-shaped cushion body 2 should just be substantially rounded, and may be a little rounded.

  However, the lateral position assisting tool 1 of the present invention may have other heights and widths such as those described above and is symmetrical. For example, it may have a substantially triangular or trapezoidal width direction cross section as shown in FIGS. 4 to 5, or may have a width direction cross section as shown in FIG. That is, the side surface and the upper surface may extend continuously from the left and right ends of the lower surface so as to form an arc having a constant curvature radius. When the cross section is substantially triangular or trapezoidal, the angle α between the left and right side surfaces and the lower surface is preferably about 30 degrees or more. In particular, when the user cannot turn over alone and needs the assistance of a caregiver, if the side surface is a vertical surface with respect to the lower surface, the cushion body that forms the lateral position assisting device The resistance is large and difficult to care for, and the fall-over difference when turning over to the opposite side of the assist device for lateral position is too large. Therefore, when the angle α between the side surface and the lower surface is set to 30 degrees or more and 40 degrees or less and the height H is formed to 3 cm or more and 5 cm or less, it is easy to turn over, and there is no concern that the turning head is large. In this case, since the user does not turn over by himself, the width of the lateral position assisting device is not particularly limited as long as it is stable on the bedding. In addition, since the user cannot move alone when he / she is turned to the complete lateral position by the caregiver after turning over, the lateral position can be maintained even after turning over.

The lateral position assisting tool 1 of the present embodiment may be formed by a plurality of parts separated from each other in the longitudinal direction. The lateral position assisting tool 1 in this case includes, for example, a first part disposed at a position corresponding to the waist on the back side of the user and a second part disposed at a position corresponding to the chest. Can do.

  In the lateral position assisting tool 1 of the present embodiment, the user can maintain a substantially complete lateral position by sleeping along the spine along the vertical side surface 3a or 3b of the kamaboko-shaped cushion body 2. Furthermore, since it has the height H and the width W that can be turned over, it is possible to overturn the lying position assisting tool 1 consciously or unconsciously. Furthermore, since the upper surface 5 is curved, such turning over can be performed smoothly.

  Furthermore, since the shape is symmetrical, the user can lie down on the lateral position assisting tool 1 by turning over to the left or right side, and the spine is in a state along the substantially vertical side surface 3a or 3b on the side where the user has climbed over. Therefore, it is possible to maintain the almost complete lateral position. By improving the lateral position rate in this way, it is possible to prevent the muscle group around the throat, which is the cause of snoring and apnea syndrome, from blocking the airway (such as tongue depression).

  However, when the body is greatly deviated from the lateral position assisting tool 1 and the lateral position assisting tool 1 is not present, the lateral position rate decreases. In the second embodiment of the present invention, the side position rate can be further improved by using together the side position assisting tool that prevents the user's lower back from moving.

[Second Embodiment]
In the second embodiment, the lateral position assisting tool 1 of the first embodiment is placed in the center of the bedding and used as the central position assisting tool 1 (hereinafter simply referred to as “central assisting tool 1”). Furthermore, at least one side-side position assisting tool 10 (hereinafter simply referred to as “side assisting tool 10”) is placed on at least one of the left and right sides of the central assisting tool 1. The set of the center-side position assist tool 1 and the side-side position assist tool 10 constitutes the side position assist tool set of the present invention.

  FIG. 7 is a top view showing the arrangement and use state of the central assisting tool 1 and the side assisting tool 10 on the bedding (the outer shape of the bedding is not shown). In the example of FIG. 7, one side auxiliary tool 10 is arranged on each of the left and right sides of the central auxiliary tool 1. Specifically, the side-side position assisting tool 10 is disposed and used at a position where it abuts on the upper end of the femur of the user 100 or the waist near the iliac as shown in FIG. As shown in FIG. 7, the user 100 lies with the spine along one of the side surfaces 3 a and 3 b of the central assisting tool 1 and presses the waist with one side assisting tool 10. A large rollover that leaves the body away from the central assisting tool 1 is caused by the movement of the waist. When you roll over, if you can stop the movement of the waist, you can rotate, but you can not move large in the lateral direction. Therefore, by pressing the lumbar part with the side assisting tool 10, the user 100 is prevented from turning over and moving away from the central assisting instrument 1 during sleep, and the lateral position rate is further improved.

  In the present embodiment, the kamaboko-shaped side position assist tool 1 of the first embodiment is used as the center assist tool, but the center assist tool used together with the side assist tool is not limited to this. As described above, it has a height H and a width W that can be turned over, and is symmetrical in other shapes, for example, the cross-section in the width direction as shown in FIGS. 4 to 5 is substantially triangular or trapezoidal. It may be of a shape, or it may have a cross section in the width direction as shown in FIG. 6, and a side surface and an upper surface may continuously form an arc having a constant radius of curvature from both ends of the lower surface. Since the details of the configuration of the central auxiliary tool 1 are the same as those described in the first embodiment, the side auxiliary tool 10 will be mainly described in this embodiment.

[Overview of side aids]
FIG. 8 is a perspective view showing the entire side assisting tool 10. In the side assist tool used in the present embodiment, at least one of the left and right side surfaces 11a and 11b forms a substantially vertical surface with respect to the bedclothes. FIG. 9 is an end view of both ends in the longitudinal direction of the side assisting tool of FIG. The side assisting tools extend over the entire length L with substantially the same width W and height H. As can be seen from FIG. 9, the side auxiliary tool of the present embodiment is a polygon having a substantially right-angled triangular cross section in which only one side surface 11a of the left and right side surfaces 11a and 11b is a vertical surface.

[Vertical surface of side assisting device]
As described above, the side assisting tool 10 used in the present embodiment is characterized in that at least one of the left and right side surfaces 11a and 11b forms a substantially vertical surface with respect to the bedclothes. The side assisting tool 10 having at least one vertical surface is advantageous in that the movement of the waist can be effectively limited by bringing the vertical surface into contact with the waist of the user. In particular, even when the central assisting tool is not a kamaboko-shaped side lying position assisting tool as in this embodiment, for example, a side assisting tool having a substantially triangular cross section, the waist is pressed by the vertical surface of the side assisting tool 10. Thus, the user's body can be prevented from moving away from the central assisting device, and the lateral position can be effectively maintained.

  When the central assisting tool 1 is not shaped like a kamaboko and the side assisting tool 10 does not have a vertical surface, it is difficult to press the waist. For example, if both the central assisting tool 1 and the side assisting tool 10 have a substantially trapezoidal cross section, if the person has sufficient physical strength to be able to turn over alone, he can freely rotate along the inclination of the side surfaces of both assisting tools. I can move. That is, as shown in FIG. 10, the back and waist easily rotate and move from the position p of the complete lateral recumbent position (waist angle 90 degrees) at the time of going to the position a and position b, and the lateral position rate decreases. To do.

On the other hand, when the side assisting tool 10 has the vertical surface 11a, the vertical surface 11a of the side assisting tool 10 can effectively prevent the movement of the waist regardless of the cross-sectional shape of the central assisting tool 1. Further, as shown in FIGS. 8 and 9, when the area of the upper surface of the side assisting tool 10 (the transition portion between the side surface 11a and the side surface 11b) is reduced, the contact area with the upper comforter is reduced. Therefore, the resistance of the upper comforter when turning over is reduced, and the position of the side assisting tool 10 on the bedding is stabilized. The side assisting tool 10 may have the same kamaboko shape as the central assisting tool 1.

  Moreover, the vertical surface 11a of the side auxiliary tool 10 should just be substantially perpendicular | vertical with respect to bedding.

[Others]
As described above, the side assisting device 10 restricts the movement of the lumbar part of the user 100 lying on the back with the central assisting device 1, so that the upper end of the femur of the user 100 or the vicinity of the iliac Used in contact with the waist. Therefore, the length L of the side position assisting tool 10 is not particularly limited as long as it is long enough to hold the upper end of the femur or the vicinity of the iliac, but if the length is too large, the user feels pressure. give. The length of the side assistance tool of this embodiment is about 10-25 cm. The width W of the side assisting tool may be a width that allows the side assisting tool to be stable on the bedding, and the height H is not particularly limited.

Moreover, the material of the side assisting tool 10 may be a foamed material such as urethane or rubber, or soft resin, which does not change much even when leaning, as in the case of the central assisting tool 1, and is approximately 200 to 600 N in the urethane JIS standard. Is preferred. The hardness can be measured by the method defined in JIS K6400 described above.

In this way, as shown in FIG. 7, the body rests from the central assisting tool 1 by lying on one side surface 3 a of the center assisting tool 1 and pressing the waist with the vertical surface 11 a of the one side assisting tool 10. It is possible to prevent separation and to further improve the lateral position rate. Further, if the side assisting tools 10 are placed one on each of the left and right sides of the central assisting tool 1, even if the side assisting tool 10 is turned over from one side and gets over the central assisting tool 1, the side assisting tool Since the waist can be pressed again by the vertical surface 11a of the other side assisting tool 10 while maintaining the lateral position by the side surface 3b, the lateral position rate can be greatly improved while enabling a large turn over.

  However, in another embodiment of the present invention, the central assisting tool and the side assisting tool may be made by filling a cylindrical cloth bag having a diameter of about 8 to 20 cm with a pillow filling material such as urethane or plastic material. The side assisting tool may be a flat cloth bag filled with a pillow filling material, urethane, plastic material, or the like. In this case, the central assisting tool and the side assisting tool can be used as a prone position assisting tool for maintaining a prone sleeping posture. Even in the prone position, it is possible to prevent tongue depression, which is the cause of apnea syndrome, and it is possible to prevent wrinkles, so there is no effect by leaning on the upper side of the cylindrical central assist device. The symptoms of respiratory syndrome can be reduced. If you use a cylindrical or flat side support with a pillow filling material, you can lie down from the side position and fit into the abdomen when you are in the prone position. The symptoms of respiratory syndrome can be reduced. In particular, the cylindrical side assist tool is soft in contact with the body and can also function as a body pillow.

  In addition, a hook-like surface of Velcro (registered trademark) is adhered or sewn to the lower surfaces of the center-side lying assist tool 1 and the side-side lying assist tool 10, and the sheets with the corresponding pile-like faces attached are bedding. The hook-shaped surface and the pile-shaped surface may be joined and used. A pile fabric knitted sheet may be used as the sheet, and the hook-shaped surface of Velcro (registered trademark) may be directly joined to the sheet. Thereby, the position on the bedclothes of the center side lying assist tool and the side lying assist tool can be fixed.

[Third Embodiment]
According to the third embodiment, the position of the lateral position assisting tool set of the second embodiment can be fixed using the fixing cloth.

In the present embodiment, the positions of the center side lying assist tool 1 and the side lying assist tool 10 are fixed to the bedclothes using a fixing cloth. When a person lying in a lateral position between the central assisting tool 1 and the side assisting tool 10 tries to turn over, the assisting tool is pushed and a large force is applied to widen the interval. For this reason, it is preferable to fix the position of the central auxiliary tool 1 and the side auxiliary tool 10 with respect to the bedding. Furthermore, the distance between the center-side position assisting tool 1 and the side-side position assisting tool 10 is preferably adjustable because there are individual differences depending on the size of the abdomen.

  In order to fix the auxiliary tool to the bedding, a pair of fixing cloths composed of a front fabric and a back fabric can be used.

   In the example illustrated in FIG. 11, a fixing cloth 22 including a front cloth 20 for covering the upper side of the central auxiliary tool 1 and the side auxiliary tool 10 and a back cloth 21 for covering the lower side of the central auxiliary tool 1 is used. The positions of the central assisting tool 1 and the side assisting tool 10 in the bedclothes and the like (not shown) can be fixed. As shown in FIG. 11, the front fabric 20 and the back fabric 21 forming the fixing fabric 22 are stitched at positions 22 a and 22 b in the substantially central portion in the width direction of the fixing fabric 22. A hole 23 for inserting 1 is formed. The fixing method can be implemented as follows. For example, first, the fixing cloth 22 is arranged on the bedding such that the hole 23 is laid and is positioned at a substantially central portion in the width direction of the bedding. After inserting the central assisting tool 1 into the hole 23, when the user is in a lateral position along the central assisting tool 1, the dimensions of the user's body, for example, the abdominal part viewed in the width direction of the fixing cloth 22 The side assisting tool 10 is arranged on the left and right sides of the central assisting tool 1 with an interval corresponding to the size (thickness), and the side assisting tool 10 is wrapped around the both end portions 20a and 20b of the front fabric 20. At this time, as shown in FIG. 11, it is preferable that the edges of the end portions 20 a and 20 b reach a position between the side auxiliary tool 10 and the central auxiliary tool 1. This is because, when the user lies between the side assisting tool 10 and the central assisting tool 1, the edges of the end portions 20a and 20b are pressed and fixed by the weight of the user.

  By this fixing method, the central auxiliary tool 1 is fixed in the hole 23 between the front fabric 20 and the back fabric 21, and the side auxiliary tool 10 is wrapped by the front fabric 20, cannot move, and firmly Fixed. Moreover, the space | interval of the center side position assist tool 1 and the side side position assist tool 10 can be adjusted by adjusting the quantity of the edge part of the surface fabric 20 which wraps the side assist tool 10. Since the distance between the center-side position assisting tool 1 and the side-side position assisting tool 10 varies depending on the person and the size of the abdomen, in this way, all persons can be accommodated.

  However, the front fabric 20 and the back fabric 21 are stitched together at one position, for example, 22a, and at the other position 22b, each of the front fabric 20 and the back fabric 21 is detachable, for example, Velcro (registered trademark) or the like. The hook side and pile surface of the tape may be sewn at positions corresponding to each other and joined to wrap the central position assisting tool 1. In this case, after the fixing cloth 22 is placed on the bedding as in the example of FIG. 11, the central auxiliary tool 1 is put into the hole 23 from the open position 22b, and then the front cloth 20 and the back cloth 21 are placed. They can be joined with Velcro at the position 22b (registered trademark).

In still another example, as shown in FIG. 12, a front fabric 30 for covering the upper side of the central auxiliary tool 1 and the side auxiliary tool 10, and a lower side of the central auxiliary tool 1 and an upper side of the side auxiliary tool 10. A fixing cloth 32 made of the back fabric 31 is used. The front fabric 30 and the back fabric 31 are stitched at positions 32 a and 32 b in the substantially central portion in the width direction of the fixing fabric 32, and a hole 33 for inserting the central auxiliary tool 1 is formed. In this case, for example, after the fixing cloth 32 is first placed on the bedding so that the hole 33 is positioned in the center in the width direction on the bedding and the central auxiliary tool 1 is inserted into the hole 33, Similarly to the example of FIG. 11, the side assisting tool 10 is arranged on the left and right sides of the central assisting tool 1 with an appropriate interval, and the side lying assist tool 10 is wrapped around the end portions 31 a and 31 b of the backing fabric 31. Also at this time, it is preferable that the edges of the end portions 31 a and 31 b reach the position between the side assisting tool 10 and the central assisting tool 1. In the example of FIG. 12, the side-side lying assist tool 10 wrapped with the back fabric 31 is further protected and fixed by being covered with the front fabric 30. In this case, if the front cloth 30 is extended to the entire width of the bedding and the end portions 30a and 30b are large enough to turn under the bedding, the entire auxiliary tool set is more stably fixed. The front fabric 30 is preferably relatively thin and soft. The hole 33 for inserting the central auxiliary tool 1 is obtained by stitching the front fabric 30 and the back fabric 31 at one position, for example, 32a, and joining them with Velcro (registered trademark) at the other position 32b. It may be formed.

  FIG. 13 shows still another example. In this example, a fixing cloth 42 composed of a front cloth 40 and a pair of back cloths 41a and 41b is used. The back fabrics 41a and 41b are stitched to the front fabric 40 at positions 45a and 45b, respectively. Furthermore, the hook and pile surfaces of a removable tape such as Velcro (registered trademark) are sewn at positions corresponding to each other on the back fabrics 41a and 41b. A hole 43 for fixing the auxiliary tool 1 is formed. In the fixing method shown in FIG. 13, for example, first, an open fixing cloth 42 in which the back fabrics 41 a and 41 b are not joined to each other by Velcro (registered trademark) is placed on a bedding (not shown). The center auxiliary tool 1 and the side auxiliary tool 10 are arranged so as to cover the upper side. Then, the back fabrics 41 a and 41 b are overlapped so as to cover the lower surface of the central auxiliary tool 1, and are joined to each other with Velcro at the joining position 44. Thereby, the central auxiliary tool 1 is fixed in the hole 43. Thereafter, the position of the side auxiliary tool 10 is adjusted, and the left and right side auxiliary tools 10 are wrapped around both ends of the back fabrics 41a and 41b as in the example of FIG. The side-side lying assist tool 10 wrapped with the back fabrics 41 a and 41 b is further protected and fixed by being covered with the front fabric 40. In this case, if the front cloth 40 has a large length that extends over the entire width of the bedding and the end portion turns below the bedding, the entire auxiliary tool set is more stably fixed.

  However, the positions of the central assisting tool and the side assisting tool may be fixed using a fixing cloth 50 made of one piece of cloth. In the example of FIG. 14, for example, a hook surface or a pile surface of a detachable tape such as Velcro (registered trademark) is sewn at a position 51 at the center of the upper surface of the cloth 50, and the lower surface of the center-side position assisting tool 1 is handled. The pile surface or the hook surface is attached to the position to be. In this fixing method, after the side auxiliary tool 10 is appropriately arranged on the bedding, the cloth 50 is arranged so as to cover the upper side of the side auxiliary tool 10. Thereafter, the central auxiliary tool 1 is fixed by joining the hook surface and the pile surface of the magic tape (registered trademark), and the side auxiliary tool 10 is wrapped and fixed at the end portions 50a and 50b of the cloth 50. it can.

Note that the fixing cloth does not need to cover the center auxiliary tool and the entire side auxiliary tool, and the dimension in the length direction is not particularly limited. That is, the fixing cloth does not necessarily need to extend over the entire length of the central auxiliary tool and the side auxiliary tool. It is only necessary to have a length that can fix the positions of the central auxiliary tool and the side auxiliary tool.

  By the way, as described above, for the prevention of apnea syndrome and snoring, it is particularly necessary and important to turn the head sideways from the chest, but the lateral position assist has a uniform height in the longitudinal direction. In the device, the entire lateral position assisting device has a relatively large height in order to make the head sideways from the chest. However, it is difficult for some users to easily get over the side position assisting device having a uniformly large height in the longitudinal direction, even if it is set to a height that can be overtaken. .

[Fourth Embodiment]
[Overview]
Hereinafter, a fourth embodiment of the present invention will be described with reference to FIGS. FIG. 15: is a perspective view which shows the whole about an example of the lateral position assistance tool 101 by 4th Embodiment of this invention. The lateral position assisting tool 101 of the fourth embodiment is common to the first embodiment in that the lateral position assisting tool 101 has a uniform width W in the longitudinal direction and is provided with a cushion body having a semi-cylindrical cross-sectional shape. However, it is different from the first embodiment in that the cushion body 102 is a stepped side support aid having a step in the height direction. In the example of FIG. 15, the cushion body 102 includes a first portion 102a having a predetermined height (first height) H1, and a second portion 102b having a predetermined height (second height) H2. The first height H1 is set smaller than the second height H2. The first portion 102a and the second portion 102b may be integrated or separated, and using a material similar to that of the lateral position assisting tool 1 of the first embodiment, by a normal method. Molded integrally or separately. In the illustrated example, the first portion 102a and the second portion 102b are separate from each other. FIG. 16 is an end view of the lateral position assisting tool 101 of FIG. 15 as viewed in the longitudinal direction from the end surface on the first portion 102a side. FIG. 17A is a plan view of the lateral position assisting tool 101, and FIG. 17B is a side view.

  FIG. 18 is a top view showing an example of the arrangement and use state of the lateral position assisting tool 101 according to the fourth embodiment on a bedding (not shown). Similar to the lateral position assisting tool 1 of the first embodiment, the lateral position assisting tool 101 of the present embodiment is arranged and used on the back side of the user who is in the lateral position on the bedding. As shown in FIG. 18, the first portion 102 a and the second portion 102 b are generally aligned in the height direction of the user 200 so as to be spaced apart or at least partially in contact with each other. The first portion 102a having a height lower than that of the second portion 102b is disposed on the back side of the waist of the user 200, and the second portion 102b having a height higher than that of the first portion 102a is disposed on the back side of the chest. The More specifically, the first portion 102a is disposed on the back side of the user 200 so as to be in contact with the waist at a position corresponding to at least the waist, and the second portion 102b is disposed at least at a position corresponding to the chest. Arranged to touch. In order to stably maintain the lateral position on the bedding, the length L1 of the first portion 102a placed on the lumbar side is a length that comes below the tailbone from the 9th thoracic vertebra, for example, 40 to 50 cm. The length L2 of the second portion 102b placed on the side is preferably a length from the 1st to the 8th thoracic vertebra, for example, 20 to 30 cm. However, these numbers may vary depending on the user's body shape.

[About the height of the lateral position assist tool]
FIGS. 19A and 19B are schematic explanatory views showing examples of the usage state of the lateral position assisting tool 101 of the present embodiment, and show the vicinity of the chest and the waist of the user, respectively. (A) shows the vicinity of the chest of the user leaning on the second portion 102b (for example, corresponding to the vicinity of the position XX in FIG. 18), and (B) shows the case of the user leaning on the first portion 102a. The vicinity of the waist (for example, corresponding to the vicinity of the position Y-Y in FIG. 18) is shown.

The lateral position assisting device 101 of the present embodiment has a height H1 of the first portion 102a so that at least the waist of the user can easily and consciously get over the first portion 102a during sleep. It is set lower than the height H2 of the second portion 102b. The lower the height H1, the easier it is to roll over the waist. Moreover, although it becomes difficult to maintain the lateral position of the waist by reducing the height H1, when the waist is rotated about 30 to 45 degrees, the chest can maintain a rotation angle different from that of the waist. Accordingly, as shown in FIGS. 19A and 19B, for example, the waist inclination angle is secured at least about 30 degrees, and the chest inclination angle is about 60 degrees by the second portion 102b having a large height. If held as described above, the head 200a of the user 200 tilts sideways, and the lateral position rate in the vicinity of the upper airway necessary for preventing apnea can be made extremely high. Therefore, the height H1 of the first portion 102a on the waist side is normally set to about 15% of the chest width, and the height H2 of the second portion 102b on the chest side is about 20 to about 25% of the chest width. Set to range. The height H2 of the second portion 102b is a range in which the chest of the user easily falls over the second portion 102b consciously or unconsciously. Since the waist and the chest interact with each other, if the waist rotates so as to get over the first portion 102a, the chest is also encouraged to get over the second portion 102b. Even if the height H2 of the second portion 102b is larger than the height H1 of the first portion 102a, the chest is cushioned because the chest height in the lateral position is larger than the waist height by the shoulder width. The resistance received from the body 102 is less than the resistance received by the waist, and it is easy to roll over. Therefore, the rotation of the entire body including the chest can be facilitated by facilitating the rotation of the waist. Thus, in the lateral position assisting tool 101 of the present embodiment, it is easier to turn the entire body of the user by facilitating the rotation of the waist, and the lateral position of the chest is reliably maintained, Airway obstruction, which is the cause of apnea syndrome and snoring, can be effectively prevented.

  In the example shown in FIG. 15, the height H1 of the first portion 102a of the cushion body 102 is set to 4 to 6 cm, and the height H2 of the second portion 102b so that it can be widely applied to both men and women having a general body shape. Is set to 6-9 cm. However, the heights H1 and H2 of the first portion 102a and the second portion 102b are not limited to the above values, and may differ depending on the body shape of the user. In particular, in the case of a large body person such as an athlete, the height may be set different from the above value. In the fourth embodiment, it is important that the first portion 102a disposed on the back side of the waist has a smaller height than the second portion 102b disposed on the back side of the chest.

[Others]
Further, the lateral position assisting tool 101 of the fourth embodiment is arranged as a center side position assisting tool on the bedclothes, and the side position assisting tool 103 having the same form as that shown in the second embodiment is replaced with the central assisting tool 103. It may be arranged on both sides of the tool 101. 18 and 19 show the use state in this case. By arranging the side assisting tools 103 on both sides of the central assisting tool 101, it is possible to hold down the waist that is the center of rotation, thereby preventing the user's body from moving away from the central assisting tool 101, and the lateral position rate Can be further improved. Further, the side assisting device 103 may be provided not only at a position corresponding to the user's waist but also at a position corresponding to the chest. As a result, the chest can be held at an angle substantially perpendicular to the horizontal plane (see FIG. 20), and the lateral position of the chest can be more effectively maintained, which is particularly important for preventing upper airway obstruction. it can.

  The uniform width W of the first part 102a and the second part 102b is normally set to about one third of the chest width of the user, like the lateral position assisting tool 1 of the first embodiment. It is preferably set to 8 cm or more and 15 cm or less so that it can be widely applied to both men and women having a general body shape.

  In the illustrated example, the first portion 102a and the second portion 102b have uniform heights H1 and H2 in the longitudinal direction, respectively, but are not limited thereto. Each of the first portion 102a and the second portion 102b may have a height that varies along the longitudinal direction, and these adjacent edges may not necessarily have a clear step. Good.

[Fifth Embodiment]
[Overview]
Next, a fifth embodiment of the present invention will be described with reference to FIGS.
FIG. 21 is a perspective view showing an example of a lateral position assisting tool 201 according to the fifth embodiment of the present invention. The lateral position assisting tool 201 of the fifth embodiment is common to the first embodiment in that the lateral position assisting tool 201 has a uniform height H in the longitudinal direction and includes a cushion body 202 having a semi-cylindrical cross-sectional shape. However, the cushion body 202 is different from the first embodiment in that the cushion body 202 is a lateral position assisting tool including a first portion 202a and a second portion 202b having different widths. The first portion 202a and the second portion 202b may be integrated or separated, and using a material similar to that of the lateral position assisting tool 1 of the first embodiment, by a normal method. Molded integrally or separately. In the illustrated example, the first portion 202a and the second portion 202b are separate bodies. FIG. 22 is an end view of the lateral position assisting tool 201 shown in FIG. 21 as viewed in the longitudinal direction from the first portion 202a side. FIG. 23A is a plan view of the lateral position assisting tool 201 of FIG. 21, and FIG. 23B is a side view. FIG. 24 shows an example of the arrangement and use state of the lying position assisting tool 201 shown in FIG. As shown in FIG. 24, as in the fourth embodiment, the first portion 202a of the lateral position assisting tool 201 is disposed on the waist side of the user 300, and the second portion 202b is disposed on the chest side of the user 300. Used for placement. Examples of the lengths L1 and L2 of the first portion 202a and the second portion 202b are the same as in the fourth embodiment.

[About the width of the lateral position assist tool]
As shown in FIG. 23A, the lateral position assisting tool 201 of the present embodiment is formed such that the first portion 202a and the second portion 202b have different widths. In the illustrated example, the first portion 202a has a single width W1, that is, a uniform width W1 with respect to the longitudinal direction. On the other hand, the width of the second portion 202b changes along the longitudinal direction. 22 and FIG. 23A, W2 indicates the width of the edge of the second portion 202b adjacent to the first portion 202a, and W3 is the opposite of the first portion 202a in the second portion 202b. The width of the edge on the side of is shown. In the fifth embodiment, the widths W1, W2, and W3 of the lateral position assisting tool are set so as to satisfy the relationship of W1 ≦ W2 ≦ W3. In the example of FIG. 23A, the widths have a relationship of W1 <W2 <W3. In particular, the second portion 202b has a trapezoidal shape with the edge on the side adjacent to the first portion 202a as the upper base. Have. Another example of the lateral position assisting tool 201 that satisfies the relationship of W1 ≦ W2 ≦ W3 is shown in FIGS. The example in FIG. 25A is an example of a lateral position assisting tool that satisfies the relationship W1 = W2 <W3, and FIG. 25B is an example that satisfies the relationship W1 <W2 = W3. However, in this embodiment, W1 = W2 = W3 may be sufficient. In this case, the lateral position assisting tool 201 has substantially the same form as the lateral position assisting tool 1 of the first embodiment shown in FIG. However, the relationship between the widths of the lateral position assisting tools in the present embodiment is as follows: W1 <W2 <W3, W1 = W2 <W3, or W1 <shown in FIGS. 23 (A), 25 (A), and 25 (B). It is preferable that W2 = W3. The reason will be described below.

In order to prevent apnea syndrome and snoring, obstruction of the upper respiratory tract due to muscle drooping around the uvula must be prevented. For that purpose, the facial angle (the angular position of the head relative to the horizontal plane in the facial direction. 19 (A)) is preferably 45 degrees or less. For example, when the chest angle is 45 degrees, the neck is located behind the face, and therefore the face angle is considered to be 45 degrees or less, which is smaller than the chest angle, due to the influence of gravity. Therefore, in order to maintain the face angle at a preferable angle, it is desirable to set the angle of the chest to 45 degrees or more. FIGS. 26A and 26B are schematic views for explaining the leaning posture of the user 300 with respect to the lateral position assisting tool 201. FIG. FIG. 26A shows a user 300 with respect to a lateral position assisting tool (for example, the lateral position assisting tool 1 according to the first embodiment) having a uniform width in the longitudinal direction for comparison with the present embodiment. In the figure, both M and M ′ indicate positions near the chest of the user 300 leaning on the lateral position assisting tool 1. FIG. 26B shows the leaning posture of the user 300 with respect to the lateral position assisting tool 201 of the present embodiment, and N in the drawing is the vicinity of the chest of the user 300 leaning against the lateral position assisting tool 201 (for example, FIG. 24 positions X′-X ′). For the sake of explanation, in FIG. 26B, the outer shape of the first portion 202a of the lateral position assisting tool 201 is indicated by a broken line.

As shown in the example of FIG. 24, when a person is in a lateral position, it is natural to fold his legs lightly, bend his waist and take a shrimp-like posture from his back to his head. That is, many people take a posture in which a light curve is drawn from the coccyx to the seventh cervical vertebra without being linear. However, as can be seen from the top view of FIG. 7, in the lateral position assisting tool 1 having a uniform width in the longitudinal direction, the side surface of the assisting tool 1 extends linearly over the entire longitudinal direction of the assisting tool 1. ing. Accordingly, as shown in FIG. 7, at the beginning of bedtime, the user lies in a substantially straight (not shrimp) posture along the side surface extending in a straight line. For example, the position near the chest of the user 300 when leaning on the lateral position assisting tool 1 at a chest angle of about 45 degrees (hereinafter referred to as “normal state”) is indicated by M in FIG.

  However, as described above, it is natural that the back of a person who is in a lateral position is lightly bent in a shrimp shape. Therefore, the posture of the user 300 after going to bed changes from a straight shape to a shrimp shape, and at this time, the position near the chest of the user 300 changes from M to M ′ shown in FIG. For this reason, as shown in FIG. 26 (A), the contact point between the chest of the user 300 after going to bed and the bedding 500 is leaning from the initial B point to the C point, usually about 3 to 4 cm. Move away from the center. As a result, as can be seen from the figure, the inclination angle near the chest is leaned and becomes considerably gentler than the original normal state, and in particular, when the side assisting tool is not used, the lateral recumbency rate may be lowered. .

  On the other hand, in the lateral position assisting tool 201 of the present embodiment shown in FIG. 21, the width of the second portion 202b arranged on the back side of the chest is such that the first portion is away from the first portion 202a side. The width is set to be gradually larger than the width of 202a. Thereby, the shape of the side surface of the lateral recumbent assisting tool 201 including the first part 202a and the second part 202b becomes a curve drawn by the person's back when the person naturally bends his back from the waist. It has a close shape. Therefore, as shown in FIG. 24, the user 300 can take a shrimp-like sleeping posture by naturally bending the body along the side surface of the assisting tool 201 whose width changes in this way from the beginning of sleeping. . Therefore, the position N near the chest of the user 300 with respect to the assisting tool 201 is substantially maintained even after going to bed. Even if the user 300 rides over the assisting device 201 and turns over, the assisting device 201 has a symmetrical kamaboko-shaped cross-sectional shape, so that the user 300 can take a natural shrimp-like posture even after turning over. The position near the chest relative to the lateral position assisting tool 201 is maintained substantially unchanged.

  In FIG. 26 (B), the contact point D between the chest at the beginning of bedtime and the bedding 500 is left by a difference in width between the second portion 202b and the first portion 202a as compared with the point B in FIG. However, since the user 300 leans on and is in a shrimp-like sleeping posture from the beginning, it does not shift after going to bed as shown in FIG. Therefore, after the user 300 leans in a normal state at the beginning of bedtime, the chest angle does not decrease and a high lateral position rate can be maintained.

  Thus, in the lateral position assisting tool 201 of the fifth embodiment, the side surface of the assisting tool can have a shape close to the curve drawn by the back when a person naturally bends the body into a shrimp shape. For this reason, compared with the case where the whole leans on the side surface which extends in a straight line, the contact point between the chest at the beginning of bedtime and the bedclothes is maintained without substantially deviating. Therefore, the decrease in the chest angle is unlikely to occur, and it is easy to maintain the chest angle in a normal state even after going to bed. For this purpose, the relationship between the widths of the lateral position assisting tool of this embodiment is the relationship shown in FIG. 23, FIG. 25 (A), or FIG. 25 (B), that is, W1 <W2 <W3, W1 = W2. It is preferable that <W3 or W1 <W2 = W3.

The width W1 of the first portion 202a is generally preferably about 8 to 12 cm in consideration of the stability of the assisting tool on the bedding, ease of getting over, the general body shape of the user, and the like. At this time, the width W3 of the edge portion on the side opposite to the first portion 202a in the second portion 202b is usually about 8 to 20 cm. However, W3 is more preferably about 2-8 cm larger than W1, and more preferably about 6-8 cm larger than W1. For example, if W1 is 12 cm and W3 is 18 cm which is 6 cm larger than this, the difference in width between the left and right sides of the lateral position assisting tool 201 can be (18-12) / 2 = 3 cm. That is, by making W3 about 6 to 8 cm larger than W1, 3 to
A width difference of about 4 cm can be provided. This difference substantially corresponds to the distance between the points B-C described above (the shift of the contact point between the chest and the bedclothes when leaning on the side surface extending linearly (see FIG. 26A)). With this, the user can take a natural shrimp-like posture along the side surface of the lateral position assisting tool 201.

  The width W2 of the edge portion on the side adjacent to the first portion 202a in the second portion 202b may be set so as to satisfy W1 ≦ W2 ≦ W3.

  However, it goes without saying that the specific values of the widths W1, W2, and W3 vary depending on the body shape of the user.

  In the fourth embodiment, an example of a lateral position assisting device including a first portion and a second portion having the same width and different heights, and in the fifth embodiment, the first portion and the first portion having the same height and different widths are provided. Although the example of the lateral position assisting tool provided with two parts was described separately, the lateral position assisting tool of the present invention may have both the features of the fourth embodiment and the features of the fifth embodiment. . That is, the second portion may have a height greater than that of the first portion and at the same time a width greater than that of the first portion.

[Others]
The uniform height H with respect to the longitudinal direction of the first portion 202a and the second portion 202b is a height at which the user can consciously or unconsciously turn over, as with the lateral position assisting tool 1 of the first embodiment. Usually, it is preferably set to about 20 to 25% of the chest width of the user, and is preferably set to 4 cm or more and 8 cm or less so that it can be widely applied to men and women of general body shape.

  Further, the lateral position assisting tool 101, 201 of the fourth embodiment or the fifth embodiment, or the lateral position assisting tool having the features of both the fourth embodiment and the fifth embodiment is the lateral position of the first embodiment. Like the assisting tool 1, it can be used with a side-side lying assisting tool that is disposed at the center of the bedclothes and is disposed on both sides or one side thereof. In this case, the position on the bedding can be fixed using the fixing method shown in the third embodiment.

[Sixth Embodiment]
[Overview]
The kamaboko-shaped lateral position assisting tool of the above-described embodiment can be used by being disposed at the approximate center on the bedding, and the user can get over and roll over and at the same time maintain the lateral position. However, persons with weak bodies, persons with a broken waist, persons with a large body weight, etc. may not be able to turn over to the extent that they can get over the lateral position assisting device. There are also people who feel resistance to the lateral position assisting device placed in the center of the bedding. A set of lateral position assisting tools suitable for such a person is provided by this embodiment.

 When a person rolls from a supine position to a recumbent position and from a recumbent position to a supine position, many persons turn over without changing the center line of the body. That is, the position of the head before turning over is almost the same as the position of the head after turning over.

  It may be difficult for a person with a weak body, a person with a deficiency in the waist, a person with a large weight, etc. to get over to the center position assisting device and to be in the side position. In the case of such a person, by utilizing the above-mentioned characteristics of turning over, the side lying position assist of the form described below is arranged on both the left and right sides of the user's body without arranging the lying position assisting tool in the center of the bedding. A high lateral position rate can be maintained only by arranging the tool set. In the side position assisting tool set of the sixth embodiment, the user can turn over so as to rotate between the pair of side position assisting tools, and can maintain the side position.

FIG. 27 shows an example of the side position assisting tool set 401 of this embodiment, which is composed of a pair of side position assisting tools 400, 400. FIG. 27 is an end view of both ends in the longitudinal direction when a pair of side position assisting tools 400, 400 constituting the side position assisting tool set 401 is arranged on the bedding 600. Each side-side support tool 400 is common to the side support tool 10 of the second embodiment shown in FIGS. 8 and 9 in that it extends with substantially the same width W and height H over its entire length. Furthermore, in the illustrated example, the cross section in the width direction is a polygon with a substantially right triangle shape, and only one of the left and right side surfaces is a substantially vertical surface, and this surface is brought into contact with the user's body. It is common with the side auxiliary tool 10 of 2nd Embodiment by the point which can be used. However, as will be described below, each side position assisting tool 400 used in the sixth embodiment is characterized by a height H, unlike the second embodiment. Further, the angle R between the side surface that is in contact with the user's body and the lower surface that is in contact with the bedding 600 does not necessarily have to be substantially a right angle.

[About height H of side position assist device]
The above-described kamaboko-shaped lateral position assisting device of the present invention can be arranged in the approximate center on the bedding and is configured so that the user can maintain the lateral position even if the user consciously or unconsciously gets over this. ing. For this reason, the height of the kamaboko-shaped lateral position assisting tool is set to about 25% or less of the chest width so that the user can get over. However, in the case of the side position assisting tool 400 used in the present embodiment, if the user easily gets over this, the effect of the present embodiment is maintained such that the side position is maintained while allowing rotation at the same position. Cannot be obtained. Therefore, the height H of the side position assisting tool 400 in the sixth embodiment is set to a height at which the user cannot easily get over this, and is usually set to about 25% or more of the chest width of the user. The If it is too high, the user feels pressure, so about 25% to 30% is preferable. Since a person with a general body shape has a chest width of about 30 cm, the height of the side position assisting tool 400 used in the present embodiment is preferably 6 to 15 cm.

FIG. 28 is a plan view showing an example of the arrangement and use state on the bedding (not shown) of the side-side lying assist tool set 401 shown in FIG. In the example of FIG. 28, one set of side position assisting tool set 401 is arranged near the chest and waist of the user. Specifically, the pair of side position assisting devices 400 are disposed so as to be in close contact with the chest in the left and right sides of the user's body, and the other pair of side position assisting devices 400 are disposed on the left and right sides of the user's body. It arrange | positions so that it may closely_contact | adhere to the waist | hip | lumbar part vicinity. The user lies in the lateral position between the two pairs of side lateral position assisting tools 400 arranged in this way.

[An angle R of the side-side position assist tool]
As described above, the angle R between the side surface and the lower surface of the side position assisting device 400 that is in close contact with the user's body is substantially a right angle in the example of FIG. 27, but is not limited thereto. Absent. As described with reference to FIG. 3, when a person lies down, the bedclothes are tilted about 10 degrees, and thereby the lateral position assisting tool is also tilted toward the user side. If this tilt is not corrected, the user feels pressure. You may feel In addition, since the side surface of the assisting device is disposed in close contact with the body, rotation without getting over the assisting device is easier when the angle R is smaller and the resistance is smaller. On the other hand, in order to maintain a lateral position where the inclination angle of the chest is 45 degrees or more, the angle between the body and the bedclothes when leaning on and contacting the upper part of the lateral position assisting tool may be 45 degrees or more. preferable. Considering these points, the angle R may be smaller than 90 degrees, and is preferably in the range of about 50 degrees to about 90 degrees, for example.

[Others]
The length H of each side-side lying assist tool 400 is normally 10 to 25 cm, which is the same as the length of the side assist tool 10 of the second embodiment. The user's abdomen is placed between the side-side position assist device (lumbar side assist device) set 401 disposed on the lumbar side and the side-side position assist device (chest side assist device) set 401 disposed on the chest side. When placed, the abdomen is not compressed. When used by a thin person or a person who does not protrude from the abdomen, a pair of side-side position assist devices having a length of about 40 to 50 cm by integrating the waist side assist devices 400 and the chest side assist devices 400 together. A set may be formed.

  The width W of each side-side lying assist tool 400 may be any width as long as the side-side lying assist tool 400 is stable on the bedding. For example, when the angle R is approximately 90 degrees, the width W is the height H. Less than twice is preferable because a stable shape can be obtained.

The material and hardness of each side position assist tool 400 are the same as those described in the first and second embodiments.

  In the side position assisting tool set 401 configured as described above, a user who lies in a lateral position between the side position assisting tools 400 and 400 does not change the body centerline between the assisting tools ( That is, the head can be turned over without changing the position of the head. Since each side-side position assisting device 400 is arranged in close contact with the body in the side-positioned posture, the user does not maintain the supine posture for a long time when turning over, and a high side-posture rate is obtained. It is done.

  In the example shown in the figure, each waist side lateral position assist tool 400 and each chest side lateral position assist tool 400 have the same shape. However, each waist side side position assist tool 400 and each chest side position assist device 400 may not have the same shape. As described above, the point of turning over is at the waist, and the rotation between the side assisting tools is less likely to rotate with less resistance when the angle R of the side assisting tool is smaller and the height H is lower. Also, since the waist and chest interact with each other, when turning over, if the chest cannot get over the assisting device, the waist rotates on the spot without getting over it even at the height at which the assisting device can get over. Accordingly, if the angle R and the height H of the chest side assist device 400 are within the above-mentioned ranges (angle R: about 50 degrees to about 90 degrees; height H: about 6 cm to about 15 cm), the waist side assist device May be smaller than the angle R of the chest side assist tool, and the height H of the waist side assist tool may be lower than the height H of the chest side assist tool. In other words, the side position assisting tool set of the present embodiment having the angle R and the height H in the above-described range may be disposed at least near the chest of the user. As a result, even if an assisting tool having a height that can be used by the user is placed near the waist, the user does not actually get over the assisting tool. Therefore, the user can turn over in the space between the side aids and can stably maintain the lateral position.

  The lateral position assisting device of the present invention can be used for treatment of people with severe hemorrhoids or patients with sleep apnea syndrome.
