Description

  The present invention relates to a posture assisting device, and more particularly, to a posture assisting device for supporting a body so as not to be in a supine posture when lying on a floor surface while being worn on the body.

  When lying on the floor, there are individual differences, but postures such as supine posture, lying posture, and prone posture are taken. However, when lying in the same posture for a long time like a bedridden state, the flow of blood to a part of the body is insufficient due to malnutrition or filth, and bed slipping is likely to occur. Until now, in order to prevent such bed slips, pillows and cushions have been applied to people who are bedridden so that they can change their positions frequently and maintain their lying posture.

  In recent years, a so-called sleep apnea syndrome has attracted attention. This sleep apnea syndrome is a general term for symptoms that stop and breathe again during sleep (apnea). Symptoms such as increased sleepiness occur. Apnea during sleep occurs because muscles that secure the airway relax due to sleep, and the tongue and soft palate are depressed by the influence of gravity to block the airway. Even if the breath does not stop, forcing air into and out of the narrowed airway causes the mucous membranes around the airway to vibrate, which causes a large snoring. And in order to prevent such apnea and snoring during sleep, it is said that it is good to sleep in a lying posture. This is because sleeping on the side causes the tongue and soft palate to be unaffected by gravity and the airway is not blocked.

  However, the recumbent posture puts a burden on the body and is difficult to maintain for a long time by itself. Therefore, development of a posture assisting tool that supports the body so as not to be in a supine posture and can easily maintain a lying posture is awaited, and many related inventions have been proposed so far.

  For example, Patent Literature 1 and Patent Literature 2 propose a posture assisting device configured to attach a supine posture suppressing unit such as a cushion or a vinyl chloride sheet to a body by a shoulder member, a waist belt, or the like (patent). Reference 1 or Patent Document 2). As a configuration similar to these, Patent Literature 3 discloses a posture assisting tool that holds and fixes a supine and hindrance body such as a ball as a supine posture suppressing unit (see Patent Literature 3).

Further, Patent Document 4 discloses a ridge having a size sufficient to maintain a lying posture, and a base portion that is related to the bottom of the ridge and is subjected to a body load on a portion extending from the ridge. A posture assisting tool constituted by the above has been proposed (see Patent Document 4).

The cutout portions 2c and 2c are formed so that the lower horizontal portion 2b is longer in the width direction than the upper horizontal portion 2a. By adopting such a shape, even when worn on the body, the notches 2c and 2c are positioned just below the heel and upper arm, so that movement of the arm is not hindered, and discomfort during wearing is reduced. can do. Moreover, since the width direction length of the lower horizontal part 2b is securable, it can mount | wear to a body firmly and can prevent the shift | offset | difference at the time of mounting | wearing. However, as will be described later, the shape of the supine posture suppression unit 2 is not particularly limited.

  Further, the supine posture suppression unit 2 is connected so that a plurality of layer portions (three in this embodiment) are connected in the left-right direction, and a central layer portion 20 is formed at the central portion in the left-right direction. Side layer portions 21 and 21 are connected to the left and right sides of the 20, respectively. The side layer portions 21 and 21 have attachment portions 22 and 22 formed on the side opposite to the central layer portion 20 side, and one ends of the belts 3 and 3 are attached to the attachment portions 22 and 22, respectively.

  The central layer portion 20 and the side layer portions 21 and 21 are made of a non-breathable thin film material having elasticity such as rubber as a raw material, and are formed so that each inside becomes a hollow bag body. . The central layer portion 20 and the side layer portions 21 and 21 are formed so as to be expanded when filled with air, and the internal space is filled with air so as to expand in a free state, that is, the interior is at atmospheric pressure. (See FIGS. 1 to 3). Further, at the boundary portion between the central layer portion 20 and the side layer portions 21 and 21 adjacent to each other, connecting portions 23 and 23 are formed along the vertical direction, and the central layer portion 20 is connected via the connecting portions 23 and 23. Side layer portions 21 and 21 are connected to both sides.

  In the upper and lower middle portions of the connecting portions 23, 23, communication hole portions 24, 24 are provided for communicating the inner spaces of the adjacent central layer portion 20 and side layer portions 21, 21 (see FIGS. 4 and 5). . That is, the air filled in the central layer portion 20 and the side layer portions 21 and 21 can freely move between the layers via the connecting portions 23 and 23. In this embodiment, since the central layer portion 20 and the side layer portions 21 and 21 are formed of a stretchable material as described above, the central layer portion 20 and the side layer portion 21 are filled with sufficient air in advance. -Even if 21 is expanded, it is configured to expand and contract by receiving and expanding air pressure. That is, in this embodiment, the internal air is moved from the adjacent layer portions 20 and 21 through the communication hole portions 24 and 24, so that the volume of each layer portion 20 and 21 is increased or decreased by the air pressure. ing.

  An air supply / exhaust cylinder 4 as an air supply / exhaust means for supplying / exhausting air to / from the internal space is integrally attached to the lower part of the surface of the central layer portion 20 and substantially in the center in the left-right direction. The air supply / exhaust cylinder 4 is provided with a vent hole communicating with the outside space in the center layer portion 20 and provided with a flange on one end side, and a plug is detachably attached thereto. When air is sent into the central layer portion 20 through the air supply / exhaust cylinder 4, air is supplied from the central layer portion 20 into the side layer portions 21 and 21 through the communication hole portions 24 and 24. When a plug is attached to the vent hole while air is supplied into the central layer portion 20 and the side layer portions 21 and 21, the central layer portion 20 and the side layer portions 21 and 21 are maintained in an expanded state. Is done.

  In a state where the central layer portion 20 is filled with air, the central layer portion 20 is expanded into a rod shape having a substantially elliptical cross section. In the state where the side layer portions 21 and 21 are filled with air, the upper tapered portion is filled with air and expanded. And the center layer part 20 is comprised so that a volume may become larger than the side layer parts 21 * 21.

  When the air in the central layer portion 20 and the side layer portions 21 and 21 is exhausted through the air supply / exhaust cylinder 4, the air is forcibly exhausted or degassed by a process reverse to the air supply described above. Then, when the plug is attached to the vent hole in a state where air is degassed from the center layer portion 20 and the side layer portions 21 and 21, the center layer portion 20 and the side layer portions 21 and 21 are degassed ( The surface is flattened). The posture assisting tool 1 in this state can be folded freely in a compact manner. As described above, the posture assisting tool 1 of the present embodiment is configured to be able to supply and exhaust the air in the central layer portion 20 and the side layer portions 21 and 21 by the air supply / exhaust tube 4, and thus the portability is improved. It is easy to handle without taking up any space.

  Further, the supine posture suppression unit 2 is configured such that the side layer portions 21 and 21 can be moved back and forth from the connecting portions 23 and 23 to displace the relative position with respect to the central layer portion 20 (see FIG. 3). ). The supine posture suppression unit 2 is configured to gently curve the surface along the cross-sectional shape of the back as a whole by displacing the relative positions of the side layer portions 21 and 21 with respect to the central layer portion 20, Since the curvature can be changed according to individual differences by moving the attachment portions 22 and 22 of the side layer portions 21 and 21 closer to or away from each other, it improves the fit when the posture assisting device 1 is worn on the body, and the displacement Can be effectively prevented.

  The belts 3 and 3 are formed in a belt shape, one end is fixed to the mounting portions 22 and 22 described above, and the other end is orthogonal to the central axis in the vertical direction of the central layer portion 20 from the mounting portions 22 and 22. It extends substantially horizontally in the direction. Each of the belts 3 and 3 is attached to the other end side with a sheet-like connecting member 30 or 30 that can be repeatedly applied and peeled off (see FIGS. 4 and 5). By being affixed, it is connected in an annular shape in plan view (see FIG. 7). The connecting member 30 is not particularly limited as long as the free end side of the belts 3 and 3 can be connected, such as a buckle or a planar fastener, and a connecting member that can adjust the connecting position is more preferable. In this embodiment, the connecting members 30 and 30 are provided with a sealing surface so that they can be attached to any position of the belts 3 and 3. By setting it as such a structure, it can be set as the length of the belts 3 * 3 according to the physical characteristic of the individual who wears the posture assistance tool 1.

  The anti-slip members 26, 26,... Are attached to the back surface of the supine posture suppressing unit 2 and to the center layer part 20, the side layer parts 21 and 21, and the fixed side ends of the belts 3 and 3, respectively. (See FIG. 5). The anti-slip member 26 is formed of a sponge material or a rubber material having a large surface friction coefficient. The shape and attachment position of the anti-slip member 26 are not particularly limited, but when the posture assisting device 1 is attached to the body, the anti-slip member 26 is attached to a shape or position that can be in close contact with the body surface.

Next, the use state of the posture assistance tool 1 will be described below.
As shown in FIGS. 6 and 7, the posture assisting tool 1 is inflated so that the air pressures of the layer portions 20 and 21 are substantially the same in a state where the layer portions 20 and 21 are filled with air, and the supine posture suppression unit 2. With the upper horizontal surface 2a facing upward, the back surface is brought into contact with the back of the body. In that case, the center layer part 20 is located in the left-right center part of the back. That is, the upper horizontal portion 2a is located between the left and right scapulae. The belts 3 and 3 are positioned above the waist of the body, extend to the front of the body, are connected by connecting members 30 and 30, and are attached to the back surface of the supine posture suppressing unit 2. Is in close contact with the body (back). In this way, the posture assisting tool 1 is attached to the body.

  The size of the supine posture suppression unit 2 is such that when an adult male is worn, the lower horizontal part 2b is positioned above the waist or the buttocks, and the notches 2c and 2c are positioned below the buttocks. However, several types of types of the supine posture suppression unit 2 can be used according to individuals (for example, a difference between men and women, a difference between adult children, and the like).

  As shown in FIG. 8A, when lying down with the posture assisting tool 1 mounted (becomes lying down), the supine posture suppression unit 2 is substantially perpendicular to the floor surface. Located in. At that time, the side layer portion 21 on the side close to the floor surface is pressed against the floor surface to be deformed with a reduced volume.

  As shown in FIG. 8B, when the posture is about to change from the lying posture to the supine posture, the side layer portion 21 is positioned between the floor surface and the body, that is, the body is the side layer portion 21. It becomes the form to get on. At that time, the side layer portion 21 is pressed between the floor surface and the body, and the air inside is moved to the central layer portion 20 adjacent to the side layer portion 21 or the other side layer portion 21, and this side layer portion. While the volume of 21 decreases, it deform | transforms so that the volume of the center layer part 20 and the other side layer part 21 may increase.

  As shown in FIG. 8 (c), when the posture is to be shifted further from the state shown in FIG. 8 (b) to the supine posture, The middle part of the back rides on. In this state, the central layer portion 20 is filled with air from the side layer portion 21 and the volume thereof is increased, so that the central layer portion 20 becomes an obstacle (failure) when the central layer portion 20 tries to move to the supine posture. Thus, the body naturally tries to return to the lying position (FIG. 8A or FIG. 8B).

  As described above, the posture assisting device 1 according to the present embodiment lies down in the mounted state, and the layer portion 20 pressed between the body and the floor surface when trying to move from the lying posture to the supine posture. Since 21 air is moved and deformed to the other layer portions 20 and 21 through the communication hole portion 24, the supine posture restraining portion 2 tries to keep the lying posture while suppressing the initial movement when trying to move to the supine posture. Therefore, the body can be reliably supported in a lying posture so as not to be in a supine posture. In addition, since the supine posture suppressing unit 2 is formed of the layer portions 20 and 21 filled with air, it is possible to turn over instead of forcing the lying posture, It can prevent adverse effects such as disturbing sleep itself. Further, since the body rides on the side layer portion 21 according to the posture change, the recumbent posture can be stabilized.

  In particular, in this embodiment, when the supine posture suppression unit 2 is pressed between the body and the floor surface, the volume of the side layer portion 21 on the side close to the floor surface is reduced, and the center layer on the side far from the floor surface is reduced. Since the volume of the part 20 and the side layer part 21 is increased, the supine posture suppressing part 2 is naturally deformed according to the posture change, and the central layer part 20 and the side layer part 21 whose volumes are increased maintain the lying posture. It becomes an obstacle to do. That is, the supine posture suppression unit 2 is deformed according to the body turning (posture change), the internal air is moved between the layer units 20 and 21, and the central layer unit 20 having an increased volume serves as an obstacle. By acting so that the body naturally returns to the original posture (recumbent posture), the recumbent posture can be reliably maintained. In particular, in this embodiment, since the volume of the central layer portion 20 is larger than the volume of the side layer portion 21, the lying posture can be more effectively maintained.

  Further, since the posture assisting device 1 is configured to be worn around the waist of the body by the belts 3 and 3, unlike a backpack type such as a shoulder belt, the posture assisting device 1 is prevented from slipping while sleeping. It is easy to wear in front and there is no stiff shoulders or discomfort when wearing. However, the mounting portion of the posture assisting device 1 may be a backpack configured by providing a shoulder strap in addition to the belts 3 and 3.

The posture assisting device 1 of the present embodiment is configured such that the supine posture suppressing portion 2 is divided into three layers of a central layer portion 20 and a pair of side layer portions 21 and 21 connected to both sides thereof. However, the present invention is not limited to this configuration, and may be partitioned into more layers. However, it is preferable to always provide the central layer portion 20 located at the left and right center of the back. As shown in the present embodiment, at least a pair of left and right side layer portions 21 and 21 are provided with respect to the central layer portion 20. Is preferred.
The supine posture suppression unit 2 may be configured by connecting layer portions 20 and 21 including a plurality of bag bodies in the left-right direction, and partitioning one bag body with the connection portions 23, 23... The layer portions 20 and 21 may be provided.
As described above, the mounting position of the posture assisting tool 1 is not only that the lower horizontal portion 2b is positioned above the waist or the buttocks when mounted, and the upper horizontal portion 2a is positioned above the waist or the buttocks by reversing the mounting position. It may be mounted so as to be positioned. That is, the wearing method can be appropriately adjusted and changed according to the wearing feeling of the individual. In addition, the most stable recumbent posture can be adjusted by adjusting the amount of air to be put into the posture assisting device 1 according to the size and weight of the body.

  Further, as shown in FIG. 9, instead of providing the communication holes 24, 24 in the connection parts 23, 23, it is formed from a non-breathable material having elasticity such as rubber along the connection parts 23, 23. You may arrange | position the made partition members 31 * 31 in the internal space of the supine posture suppression part 2. FIG. The partition members 31, 31 are arranged so as to partition the internal space between the central layer portion 20 and the side layer portions 21, 21, and the communication holes 124, 124,. A plurality of holes are drilled along the longitudinal direction. As in the above-described embodiment, the internal air is moved from the adjacent layer portions 20, 21 through the communication hole portions 124, 124,. The volume is configured to be increased or decreased by air pressure. The partition members 31 and 31 can be formed of the same material as the layer portions 20 and 21 of the supine posture suppression unit 2.

  By providing the partition members 31 and 31 in this way, breakage due to the load applied to the communication hole portions 124 and 124 can be reduced. That is, a large load is applied to the communication hole portions 24 and 124 due to the air pressure moving between the layer portions 20 and 21. However, when the communication hole portion 124 is formed in the partition member 31 that is a single member, such a load is applied. Can withstand the structure.

  Furthermore, as shown in FIG. 10, in the supine posture suppression unit 102, the side layer portion 121 is extended so that the volume gradually decreases from the central layer portion 120 in the left-right direction so as to have a substantially crescent shape in cross section. As a whole, the central layer portion 120 and the side layer portion 121 may be integrally formed. That is, unlike the embodiment described above, the inner space of the central layer portion 20 and the side layer portion 21 is connected continuously, that is, without the connection portion 23 and the communication hole portions 24 and 124 being provided. Is formed. The supine posture suppression unit 102 is curved in an arc shape so that the cross-sectional curvatures of the front surface and the back surface are different (so that the curvature of the front surface is increased), so that the volume at the center in the left-right direction is maximized. It is formed, the fit to the body is enhanced, and the restraining force on the supine posture is improved. The belt 3 is connected to the left and right end portions of the extended center layer portion 120.

  As described above, the supine posture suppression unit 102 is formed by extending the central layer portion 120 in the left-right direction so as to be formed of a single member, so that the connecting portion 23 and the partition member 31 described above are not necessary. Becomes easy. Further, the air movement between the layers becomes smooth, and it is easy to elastically deform into a shape that holds the supine posture according to the switching of the posture.
