4.4. . . . indicates an air bar inserted into each air bar insertion hole 2, and each air bar 4 is inserted into the pinerest main body 1.
It is formed as a telescopic long cylindrical body having a length approximately equal to the widthwise dimension of the air bar insertion hole 2 and a diameter approximately equal to the diameter of the air bar insertion hole 2 .

Further, both end surfaces of each air bar 4 are closed, and when air is supplied to the inside thereof, the bar expands, and when the air is exhausted, the bar 4 contracts due to the weight of the patient. Here, each of the air holes 4 is resin-molded, for example, from soft vinyl chloride.

Reference numeral 5.6 denotes air piping for supplying and discharging air to each of the air pars 4. One air piping 5 is connected to each air par 4 at one interval, and the other air piping 6 is connected to the air piping 5. It is connected to each of the other air pars 4 which are not connected to the air par 4 (see FIG. 3). Reference numeral 7 denotes an air source device for supplying and discharging air to each of the air pipes 5.6, and the air source device 7 includes a compressor, an electromagnetic switching valve that switches the air pipes 5.6 between the compressor side and the exhaust side, A timer or the like is built in to control switching of the switching valve at predetermined intervals (for example, every 5 minutes). Therefore, when the air source device 7 is started and the air piping 5 side is the air supply side and is supplying air in the direction of arrow A in FIG. 3, the air piping 6 side is the exhaust side and the Air is exhausted in the direction of arrow B in FIG. 3, and the air pars 4 are alternately inflated and contracted (see the shaded area in FIG. 3).

8.8. . . . indicates an air jet pipe inserted into each air jet pipe insertion hole 3, and each air jet pipe 8 also has a length approximately equal to the width direction dimension of the pine mattress main body 1,
It is constructed as a relatively hard elongated cylindrical body having a diameter approximately equal to the diameter of the air jet tube insertion hole 3. Further, each of the air jet pipes 8 has a large number of air jet ports 8A located at the top thereof.

8A, . . . are respectively formed to blow out the supplied air (see Fig. 4). Note that as the air jet pipe 8, for example, a hard vinyl chloride pipe is used.

Furthermore, 9 is an air pipe for supplying air to each of the air jet pipes 8, 10 is an air a device with a dehumidifying mechanism that supplies dehumidified clean air to the air pipes 9, and the air source device 1
A compressor and a dehumidifier are built into the unit. Therefore, when the air source device 10 is started, clean air is supplied to each air jet pipe 8 through the air piping 9, and air is jetted from the air jet port 8A, so that the Air is emitted in a gentle breeze to provide dry air stimulation to the patient, further increasing its effectiveness in preventing bedsores.

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

First, when the air source device 7 is activated, air is supplied and discharged to and from each air bar 4 at intervals of one bar and at a predetermined period via the air piping 5.6. Therefore, the air par 4 to which air is supplied expands and acts to push up the mattress body 1, and the air par 4 from which air is exhausted acts to contract depending on the weight of the patient.

As a result, the pinerest body l expands and contracts, and for the patient sleeping on it, the pinerest body itself feels soft and undulating, allowing the patient to change their position without any discomfort. . Further, in combination with the flexibility of the pinerest main body 1, a sound sleep effect can be achieved. Furthermore, since the uneven movement is not as intense as in the prior art, a good pine surge effect can be achieved.

On the other hand, when the air source device 10 is started, dehumidified air is supplied to the air jet pipe 8 via the air pipe 9 and is jetted from the air jet port 8A. Therefore, the ejected air spreads into the pinerest main body 1 and blows out 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. In addition, the air source device 10 is equipped with a near-conditioning device capable of cooling or heating, and the near-conditioned air is supplied to the air jetting pipe 8 and jetted from the air jetting port 8A, thereby preventing pine tress. Since cool or warm air can be diffused over the entire surface of the main body 1 and blown out, it can be extremely comfortable.

Furthermore, when cleaning the mattress main body 1, it can be easily cleaned by removing the air parser 4 and the air jet pipe 8.

Next, FIGS. 6 and 7 show the second embodiment of the present invention. A third embodiment is shown in which the same components as those in the first embodiment are denoted by the same reference numerals, and their explanations will be omitted.

However, the feature of the second embodiment shown in FIG. 6 is that instead of the air bar insertion hole 2 having a circular cross section in the first embodiment, an air per air jet pipe insertion hole 1) having a non-circular cross section is bored. The air pur 4 and the air jet pipe 8 are inserted into the insertion hole 1) as one body. With this configuration, the air jet tube insertion hole 3 can be made unnecessary.

Further, the feature of the third embodiment shown in FIG.
The air bar section 21B and the air jet pipe section 21C are defined by the partition wall 21A. Note that the air jet pipe portion 21C is provided with a large number of air jet ports (not shown). With this configuration, the air jet pipe 8
Since the air par 21 can also serve as the air blower 21, the air jetting pipe insertion hole 3 and the air jetting pipe 8 can be made unnecessary.

The embodiment of the present invention is as described above, and in the embodiment, the air par 4 (21) and the air jet pipe 8 are arranged in the width direction, but they are arranged in the longitudinal direction of the pinerest main body 1. Good too.

Furthermore, the air to be supplied and discharged to and from the air bars 4 (21) is not limited to one bar interval, and air may be supplied to and discharged from all air bars 4 (21) at the same time, or air may be supplied to and discharged from the air bars 4 (21) sequentially. , these can be determined as appropriate depending on the number of air pipes, the operating order of the switching valves in the air source device 7, etc.

Further, in the embodiment, the air source device 7 for the air bar 4 and the air source device 10 for the air jet pipe 8 are separately provided, but each of these air source devices 7 and 10 is provided as a single air source. It may also be used as a device.
