BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thickness and hardness adjustment function capable of changing hardness and thickness in order to cope with prevention of pressure sores, ie, bedsores, and rehabilitation. It is related to the provided mattress.

[0002]

2. Description of the Related Art For example, bedridden elderly people and patients undergoing long-term medical care tend to have bedsores. As a countermeasure for such bedsore, as shown in FIG. 9, an air mattress 1 or a urethane foam mattress is laid on a general mattress 2 for use. On the other hand, it is said that mattresses suitable for long-term caregivers who are recovering are of a harder and thinner type. As described above, mattresses suitable for bedsores countermeasures and mattresses suitable for patients who have recovered before functional recovery training have conflicting characteristics. Are used properly.

[0003]

In order to properly use such mattresses, the mattresses are replaced on the floor. However, it takes time and effort to replace the mattresses, and a place for storing the mattresses removed by the replacement is secured. There is also a problem to do. The present invention has been proposed in order to solve such problems, regardless of the patient's illness, so that it is not necessary to replace, so that it can be used together by changing the hardness and thickness, An object of the present invention is to provide a mattress having a function of adjusting hardness and hardness.

[0004]

In order to achieve the above-mentioned object, the present invention provides at least a relatively hard filling,
A relatively soft porous filling is sealed in a cover member, and an air suction port for sucking air in the cover member is protruded from the cover member so that suction means can be connected. It is possible to adjust the overall thickness and adjust the overall elasticity by sucking the air in the cover member and compressing the soft porous filler in the thickness direction according to the usage conditions. And Further, the present invention is configured such that a compressed bag filled with urethane foam and the compressed bag are sandwiched between a relatively hard first urethane foam and a relatively soft second urethane foam, and these first urethane foam, The compression bag and the second urethane foam are wrapped by a bottom cover and a top cover, and the bottom cover and the top cover are sealed by a cloth member that expands and contracts in a thickness direction. An air suction port for sucking the inside air wrapped in the air inlet is formed, and a suction means can be connected. In the above-described configuration, the bottom cover and the top cover are operated by a suction means through an air suction port, and the inside air wrapped by the bottom cover and the top cover is sucked, so that the thickness of the entire bottom is increased. A fastener for joining the bottom cover and the top cover when the hardness is adjusted while compressing the length direction is provided. Further, the bottom cover is constituted by a member having a relatively high friction coefficient, while the top cover is constituted by a member having a relatively low friction coefficient.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a mattress having a thickness and hardness adjusting function according to the present invention will be described below with reference to the accompanying drawings with reference to one embodiment. FIGS. 1 and 2 show a mattress 10 having a thickness and hardness adjusting function. The mattress 10 having a thickness and hardness adjusting function is formed by sealing a urethane foam, which will be described later, with a cover member 11. It is stopped.
The cover member 11 has a configuration in which the bottom cover 11a and the top cover 11b are sewn together via a stretchable cloth member 12 that can expand and contract in the thickness direction of the mattress 10. A connecting portion 13a forming an air suction valve 13 protrudes from one end surface of the cover member 11 in the longitudinal direction, and is connected to a vacuum cleaner 14 to suck air in the cover member 11 by the vacuum cleaner 14. It is a configuration to do. The air suction valve 13 is configured to be attached to a bag (to be described later) filled with a filling in the cover member 11. Further, the bottom cover 11a and the top cover 11b receive the stretchable cloth member 12 therein when the mattress 10 contracts in the thickness direction.
A fastener 15 for engaging the top cover 1a with the top cover 11b is provided. Also, the bottom cover 11a includes:
A cloth member is applied to the bottom of the bed to be placed on the mattress so that it is not slippery due to a moderate frictional force. On the other hand, the top cover 11b is provided so that the patient's body can easily move on the mattress. In order to suppress stress due to frictional resistance to the skin, which is one of the factors, and to effectively disperse body pressure on the skin surface, a low friction cloth member is applied.

[0006] As shown in Figs. 3 and 4, the filling in the cover member 11 is, for example, a compression bag 16 filled with urethane foam and a comparatively lower side of the compression bag 16 in the figure. A rigid first urethane foam plate 17,
A configuration in which a relatively soft second urethane foam plate 18 is arranged on the upper surface side of the compression bag 16 can be shown. The urethane foam, the first urethane foam plate 17 and the second urethane foam plate 18 in the compression bag 16 are a porous elastically deformable foam.

[0007] An air suction valve 13 is attached to the compression bag 16 and, as described above, the bottom cover-1 is provided.
When the first urethane foam plate 17, the compression bag 16 and the second urethane foam plate 18 are wrapped by 1a and the top cover 11b, the connection portion 13a of the air suction valve 13 is connected from the bottom cover 11a and the top cover 11b. It is made to protrude. In addition to the vacuum cleaner 14, a vacuum suction means (not shown) provided on the wall of the hospital room can be connected to the connection portion 13a, and the air inside the cover member 11 wrapped around is sucked, and the mattress 1 is sucked.
0 The thickness is reduced in the thickness direction and the hardness is adjusted.

The air suction valve 13 has a structure in which air does not flow back into the cover member 11 even when the vacuum cleaner 14 is detached. On the other hand, the valve can be manually opened to suck air. The first urethane foam plate 17, the compression bag 16 and the second urethane foam plate 18 compressed in the width direction are returned to the original thickness again, and the entire thickness of the mattress 10 can be returned to the original thickness. I have. That is, the thickness and hardness of the entire mattress 10 can be adjusted by operating the air suction valve 13 so as to open the valve body appropriately and cut off the inflow of air on the way. is there.

The mattress 10 having the functions of adjusting the thickness and hardness according to the present invention is configured as described above. Next, the operation thereof will be described. When the patient is bedridden and cannot turn over, the mattress 10 is used in its original thickness. At this time, the second urethane foam plate 18 on the upper surface side of the compression bag 16 can appropriately disperse the patient's body pressure and prevent bedsores. In this state, the mattress 10 is still filled with the compression bag 1
6. Since the first and second urethane foam plates 17 and 18 are integrally accommodated in the cover member 11, there is no feeling of instability as if different mattresses were merely superimposed.

[0010] On the other hand, when the patient recovers and turns over, in order to perform function recovery training, it is necessary to raise the upper body and hold the posture on the mattress 10 in order to perform the function recovery training. In the state of being too soft, it becomes too soft and unstable. Therefore, when vacuum suction means provided on the wall of the hospital room or a vacuum cleaner 14 is connected to the connection portion 13a of the air suction valve 13 to suction the air inside the wrapped cover member 11 (see FIG. 5), especially compression is performed. The second urethane foam plate 18 on the upper surface side of the bag 16 shrinks in the thickness direction and becomes thinner. As a result, the overall thickness of the mattress 10 is reduced (see FIG. 6), so that the bottom cover 11a and the top cover 11b are
The sealing is performed by the fastener 15 (see FIG. 7). Thus, the soft second urethane foam plate 18
When the air inside is evacuated, the thickness, that is, the volume is reduced, the elasticity is also reduced, and the compression bag 16 and the harder first urethane foam plate 17 greatly influence the determination of the hardness of the mattress 10. Thus, the mattress 10 having a suitable hardness during the function recovery training can be obtained.

When returning the mattress 10 to the initial thickness from the state of the mattress 10 suitable for the function recovery training as described above, the air suction valve 13 is operated to open the inside of the cover member 11 to the atmosphere. (See FIG. 8). If the air suction valve 13 is operated on the way and the air release state is shut off again, the compression bag 16 and the first urethane foam plate 17 including the second urethane foam plate 18,
It is understood that the mattress 10 can be appropriately adjusted in thickness and hardness by operating the air suction valve 13 because the mattress 10 is maintained in the middle of the restored state instead of the completely restored state. Therefore, it is possible to adjust the mattress 10 to a desired hardness and thickness as well as the patient's illness, and it can be said that the mattress 10 is excellent in usability.

[0012]

As described above, according to the present invention, the thickness and hardness of the mattress can be adjusted by adjusting the amount of air in the mattress. Mattresses and mattresses suitable for patients who have recovered before performing functional recovery training can be made to correspond, and according to the patient's illness, recovery status, it is not necessary to replace mattresses for different purposes, This eliminates the need for any work, thus reducing labor and further contributing to a reduction in equipment costs.
