It has been derived. The communication pipes 7 and 8 are resin-molded, for example, from relatively hard vinyl chloride.

Reference numeral 9 denotes an air pipe for supplying and discharging air to each air bag 6, and the air pipe 9 is connected to two air pipes 9.
A, 9B, one air pipe 9A is connected to each communication pipe 8 at one interval, and the other air pipe 9B is connected to each communication pipe 8 that is not connected to one air pipe 9A. The tubes 8 are connected to each other (see FIG. 4).

Further, reference numeral 10 denotes an air source device for supplying and discharging air to the air piping 9, and the air source device 10 includes a compressor and an electromagnetic device that switches the air piping lines 9A and 9B of the air piping 9 between the compressor side and the exhaust side. A switching valve and a timer for switching and controlling the switching valve at predetermined intervals (for example, every 5 minutes) are built-in. Therefore, when the air source device 10 is started and the air pipe 9A is on the air supply side and is supplying air in the direction of arrow A in FIG. 4, the air pipe 9B is on the exhaust side. As a result, air is exhausted in the direction of arrow B in FIG. 4, and each air bag 6 is alternately inflated and contracted (see the shaded area in FIG. 4).

The present embodiment is constructed as described above, and its operation will be described next.

First, when the air source device 10 is started, air is supplied and discharged to and from each air bag 6 in the longitudinal direction through the air piping 9 and the communication pipes 8 and 7 at intervals of one air bag and at a predetermined period. Therefore, the air bag 6 supplied with air expands and acts to push up the mattress body 1, and the air bag 6 from which air is exhausted acts to contract according to the patient's weight.
The pinerest main body 1 is in a state as shown by the two-dot chain line C in FIG.

As a result, the pinerest main body 1 is in a state of expansion and contraction, and the patient sleeping on it feels a gentle wave-like sensation in the pinerest main body 1 itself, and can exert the effect of changing the body position without feeling discomfort. . In addition, in combination with the flexibility of the pinerest main body 1, a sound sleep effect can be achieved. moreover,
Since the uneven movement is not as intense as in the prior art, a good pine surge effect can also be achieved.

is made to protrude from the surface of the upper pinerest 11. In addition, communication pipe insertion holes 12A, 12A, . . Then, communication pipes 13, 13, . , each of the communication pipes 13 is connected to the communication pipe 14, respectively.

Since the present embodiment is constructed in this manner, the air bag 6 is in a state of slightly protruding from the surface of the upper mattress 11, and the pine surge effect can be further enhanced compared to the first embodiment. In addition, since the communication tubes 13 and 14 are arranged on the bottom side, they do not come into contact with the sleeping patient's body, thereby eliminating the lumpy feeling.

Next, FIG. 6 shows a third embodiment of the present invention,
The feature of this embodiment is that each air bag 6 is connected to a communication pipe 21,
21, . . . and these communication pipes 21 are connected to the air pipes 9A, 9B of the air piping 9 via the communication pipes 22.

Since the present embodiment is constructed in this way, the airbag 6 expands and contracts alternately in the width direction, and can exhibit a body position changing effect different from that of the first embodiment.

Furthermore, FIG. 7 to FIG. 9 show a fourth embodiment of the present invention, and the feature of this embodiment is that by embedding an air jet pipe in the pinerest body, a breeze is emitted from the surface of the pinerest, which is effective in preventing bedsores. The reason is that we have tried to further increase the

33 is an air pipe for supplying air to each of the air jet pipes 32; 34 is an air source device equipped with a dehumidifying mechanism that supplies dehumidified clean air to the air pipes 33; It has a built-in compressor and dehumidifier. Therefore, the air source device 34
When activated, clean air is supplied to each air jetting pipe 32 via the air piping 33, and by jetting air from the air jetting port 32A, air is blown out in a breeze from the surface side of the pine mattress body 1. death,
The dry air provides stimulation to the patient, further increasing its effectiveness in preventing bedsores.

The present embodiment is configured as described above, but when the air source device 34 is activated, dehumidified air is supplied to the air jet pipe 32 via the air pipe 33 and is jetted from the air jet port 32A. Therefore, the ejected air is diffused into the pine mattress main body 1 and emitted from its surface in a breeze. As a result, the patient can be stimulated by the dry air, and the effect of preventing bedsores can be further enhanced. Moreover, the air source device 3
4 is an air source device equipped with an air conditioning device capable of cooling or heating, which supplies air conditioned to the air jet pipe 32;
