Description

In the present invention, the body of a sick person who has been bedridden for a long time for a long time is rubbed due to pressure on the weight, and the part that is hitting the futon or mat is swollen red, causing pain and causing pain to the sick person. The present invention relates to an air mat device for preventing floor slip for preventing floor slip.

A sick person who has been bedridden for a long time is always in contact with a mat or a futon, so that the contacted part becomes congested, causing bed slippage and causing pain to the sick person. In order to prevent this bed slip, it is necessary to keep the body away from the mat or futon to avoid congestion, and for that purpose, a pillow-shaped or circular-shaped instrument is inserted between the body and the mat. ing. However, if such instruments are continuously inserted over a long period of time, the part becomes painful or the part newly causes bed slipping, so it is necessary to change the position of these instruments or remove them appropriately. However, there are many bedridden people who are bedridden, and the position of the device cannot be changed or removed by themselves, and the caregiver's hand has to be bothered.

Therefore, there are two mats that can be automatically expanded and contracted by air, as described in the following patent document, which can automatically change the position of the sick person without bothering the sick person or the caregiver. These have been proposed in which each body is expanded or contracted to change its posture to the left or right.

May be.

The joining means 7 for polymerizing and fixing the upper air mat 1a and the lower air mat 1b so that they can be joined / separated over the upper and lower two stages is composed of the upper air mat 1a and the lower air mat 1b. There is no particular limitation as long as it can be joined / separated over the lower two stages, but it is preferably bonded and fixed using the surface fastener male piece 7a and the surface fastener female piece 7b, respectively. Is recommended.

The operation of the device of the present invention having the above configuration will be described. First, when the sick person P uses the apparatus of the present invention, the upper and lower air mats 1a and 1b are superposed and fixed by the joining means 7 over the upper and lower two stages, while the upper and lower air mats 1a and 1b are fixed. The wide air tubes 3 and the small air tubes 4 that are placed on the bed B and inject air from the air pump 9 through the inlets 5 to constitute the upper and lower air mats 1a and 1b. Inflate each.

When the upper and lower air mats 1a and 1b are inflated, as shown in FIG. 2, the upper and lower air mats 1a and 1b that are polymerized are located on the bed B with the connecting piece 2 portion positioned at the lowest position. It will be in the state where it was mounted. In this state, when the sick person P lies on the upper air mat 1a, as shown in FIG. 3, the connecting piece 2 portion located at the lowest position in the center is located in the spine of the sick person P. Since the both side portions are positioned on the wide air tubes 3 of the upper air mat 1a, the spinal column portion is in a lifted state, and is not in contact with the connecting piece 2 and the wide air tubes 3 and is not compressed. No congestion occurs and no spinal displacement occurs in the spinal column. The upper and lower air mats 1a and 1b placed on the bed B are not shown in the drawings, but sheets or thin mattresses or mats should be used. Is preferred.

In the state where the sick person P lies on the upper air mat 1a, when the air in the wide air tube 3a on the left side of the upper air mat 1a is exhausted using the air pump 9, the wide air on the left side is exhausted. As the tube 3a gradually contracts, as shown in FIG. 4, the sick person P gradually tilts to the left side by about 30 ° gradually while the right half of the body is in contact with the wide air tube 3b on the right side. Since the center of gravity moves to the left side, the contact pressure to the wide air tube 3b on the right side of the sick person P gradually weakens and the congested state is gradually released to promote blood flow in the right back part of the sick person P. To prevent bed slipping. And at this time, even if the sick person P is inclined to the left side, the left-side small air tubes 4a and 4c located on the outside in the left direction are in a state of being expanded without being contracted, The inflated small air tubes 4a and 4c serve as a stopper, so that the sick person P is not slipped down and the inclined state can be maintained.

Further, in order to increase the inclination angle of the sick person P to the left side from the state shown in FIG. 4, when the air in the wide air tube 3c on the left side of the lower air mat 1b is exhausted, the wide side on the left side is exhausted. As the air tube 3c gradually contracts, the sick person further tilts about 45 ° to the left and the center of gravity moves further to the left as shown in FIG. The contact pressure to the wide air tube 3b is further weakened, the blood congestion state disappears, and blood flow can be further promoted, so that bed slippage is prevented. And at this time, even if the sick person P is further inclined to the left side, in the left direction, the left-side small air tubes 4a and 4c located outside are in a state of being expanded without being contracted, The inflated small air tubes 4a and 4c serve as a stopper, so that the sick person P is not slipped down and the inclined state can be maintained.

Further, in order to further increase the inclination angle of the sick person P to the left side from the contracted state of the wide air tubes 3a and 3c on the left side of the upper and lower air mats 1a and 1b shown in FIG. 5, as shown in FIG. In addition, the narrow air tube 4a on the left side of the upper air mat 1a is contracted together with the wide air tubes 3a and 3c on the left side of the upper and lower air mats 1a and 1b, so that the inclination angle of the sick person P to the left side is increased. Since the center of gravity moves completely to the left side by setting it to about 75 °, the contact pressure on the wide air tubes 3b and 3d on the right side of the back of the sick person P is lost, and the congested state disappears. Therefore, it is possible to prevent a bed slip. At this time, since the small air tube 4c on the left side of the lower air mat 1b remains inflated without contracting, the small air tube 4c in the expanded state serves as a stopper, and the sick person P is displaced. It does not fall, and the inclined state to the left side can be maintained.

The sick person P inclined to the left side maintains that state for a certain period of time, and then the wide air tube 3a on the left side of the contracted upper air mat 1a, the wide air tube 4a on the left side, and the wide air on the left side of the lower air mat 1b. Air is injected into the tube 3c using the air pump 9 to return to the initial state shown in FIG.

Next, in order to incline the sick person P to the right side, when the air of only the wide air tube 3b on the right side of the upper air mat 1a is exhausted using the air pump 9, as shown in FIG. While the half body is in contact with the wide air tube 3a on the left side and gradually tilts to the right side by about 30 ° and the center of gravity moves to the right side, the sick person P gradually tilts to the right side. The contact pressure to the wide air tube 3a on the left side of the sick person P gradually decreases, and the blood congestion state is gradually released to promote blood flow in the left part of the sick person, thereby preventing bed slipping. . At this time, even if the sick person P is tilted to the right side, the right small air tubes 4b and 4d located on the outside in the right direction remain inflated without contracting. The inflated small air tubes 4b and 4d serve as a stopper, so that the sick person P is not slipped down and the inclined state can be maintained.

In order to increase the inclination angle of the sick person P to the right side from the state shown in FIG. 7, when the air in the wide air tube 3d on the right side of the lower air mat 1b is exhausted, the wide side on the right side is exhausted. As the air tube 3d gradually contracts, the sick person P is further inclined to the right side by approximately 45 ° as shown in FIG. 8, and the center of gravity moves further to the right side. The contact pressure to the wide air tube 3a is further weakened, the blood congestion state is eliminated, and blood flow can be further promoted, thereby preventing back slippage. At this time, even if the sick person P is further inclined to the right side, the left-side small air tubes 4b and 4d located on the outside in the right direction are in a state of being expanded without being contracted. The inflated small air tubes 4b and 4d serve as a stopper, so that the sick person P is not slipped down and the inclined state can be maintained.

Furthermore, in order to further increase the inclination angle of the sick person P to the right side from the contracted state of the wide air tubes 3b and 3d on the right side of the upper and lower air mats 1a and 1b shown in FIG. In this way, the narrow air tube 4b on the right side of the upper air mat 1a is contracted together with the wide air tubes 3b and 3d on the right side of the upper and lower air mats 1a and 1b, and the inclination angle of the sick person P to the right side Since the center of gravity completely moves to the right side by increasing the angle to about 75 °, the contact pressure to the wide air tubes 3a and 3c on the left side of the back part of the sick P disappears, and the congested state disappears. Since further blood flow can be promoted, bedsores can be prevented. At this time, the small air tube 4d on the right side of the lower air mat 1b remains inflated without contracting, so that the small air tube 4d in the expanded state serves as a stopper, and the sick person P is displaced. It does not fall, and the inclined state to the right side can be maintained.

As described above, the operation of inclining the sick person P to the left side and then to the right side is repeated using the air pump 9, so that the position of the sick person P is automatically converted, and the futon and mat of the sick person P are automatically converted. Since the contact pressure that hits the contact is eliminated and the blood stasis state is released, bed slip can be prevented. Further, in the case of the manual operation, the inclination angle and the inclination time of the sick person P can be arbitrarily set.
