Detailed Description

Embodiments of the present utility model will be described below with reference to the drawings.

< first embodiment >

Embodiments of the present utility model will be described below with reference to the drawings. Fig. 1 shows a top view of a ventilation mattress 1 of a first embodiment. Fig. 2 and 3 show a sectional view A-A and a sectional view B-B of fig. 1, respectively. The ventilation mattress 1 includes a cushion portion 10. The person H to be treated lies on the pad 10. The cushion 10 is provided with a plurality of air bags 40 as treatment members, and the air bags 40 are used to treat the person H lying on the cushion 10. The airbag 40 is a generic term for airbags 41 to 46 described later.

The ventilation mattress 1 is also provided with an air supply device 2. The air supply device 2 can supply at least one of cool air and warm air. For example, the air supply device 2 can supply cool air that is colder than the outside air, warm air that is warmer than the outside air, and the like. The air supply device 2 can supply air having a lower humidity than the outside air. The present example does not exclude a configuration in which the air supply device 2 can supply air having a temperature equivalent to the outside air temperature.

A plurality of hoses 6 are connected to the air supply device 2. A tube bundle 5 consisting of a plurality of hoses 6 extends from the air supply 2. The air supply device 2 supplies air to the air bags 40 via the hoses 6, as will be described in detail later.

The cushion 10 has a plurality of support plates 11, 12, 13 and an air accumulation unit 60. The support plates 11, 12, 13 are covered by a buffer 18. The air accumulation unit 60 is disposed on the support plates 11, 12, 13 and can accumulate air. The air accumulation unit 60 is a generic term for air accumulation units 61 to 66 described later. The outside of the cushion 18 is covered with a cloth cover (not shown). The cover is formed of a cloth material capable of expanding and contracting at least the side peripheral surface, and is capable of expanding and contracting in response to expansion and contraction of the airbag 40.

The plurality of support plates 11, 12, 13 are arranged in parallel in one direction. A coupling portion 18a formed by a damper 18 is provided between the support plates 11, 12, 13. The plurality of support plates 11, 12, 13 are disposed in parallel so as to be bendable at the connecting portion 18a. As will be described later, each of the support plates 11, 12, 13 has a connection portion 19 with the hose 6. Therefore, the cushion 10 can be folded and stored. At this time, unlike the conventional structure in which the hose 6 is disposed in the pad 10, damage to the hose 6 due to repeated bending does not occur. Therefore, the air supply/discharge failure caused by damage to the hose 6 in the pad 10 can be prevented.

The support plates 11, 12, 13 are provided with air bags 40, respectively. For example, the support plate 11 is provided with air bags 41 and 42 for treating the neck and shoulder of the person H to be treated. The support plate 12 is provided with air bags 43 and 44 for treating the waist of the person H to be treated. The support plate 13 is provided with air bags 45 and 46 for treating the legs of the person H to be treated.

The support plates 11, 12, 13 have a lower layer 15 and an upper layer 16, respectively. A groove 20 is formed in the upper surface of the lower layer 15. The upper layer portion 16 is fixedly connected to the upper surface of the lower layer portion 15. Further, an air accumulation portion 60 is formed in the upper layer portion 16. For example, in the present embodiment, the through-hole 30 is formed in the upper layer portion 16. An airbag 40 is disposed directly above the through hole 30. In the present embodiment, the air accumulation unit 60 includes the through hole 30 and the airbag 40. The groove 20 is a generic term for the grooves 21 to 25 described later. The through-holes 30 are a generic term for the through-holes 31 to 36 described later.

The air accumulation portion 60 (i.e., the through hole 30 and the air bag 40) is connected to the air supply device 2 via the groove portion 20 and the hose 6. One end of the groove 20 is connected to the air supply device 2 via the hose 6. The other end of the groove 20 is connected to the air accumulation portion 60, specifically, to the through hole 30.

In this way, for example, by supplying cool air or warm air to the air accumulation portion 60 through the groove portion 20, the body part of the treatment subject H located directly above the air accumulation portion 60 (particularly, the air bag 40) can be locally cooled or warmed. Thus, the ventilation mattress 1 can provide a comfortable sleeping feel to the person H to be treated.

The groove 20 through which the air supplied from the air supply device 2 flows is disposed in the lower layer 15 of the support plates 11, 12, 13, and is connected to the air accumulation portion 60 disposed in the upper layer 16. This can omit the arrangement of members such as the air supply hose in the cushion portion 10. Therefore, the ventilation passage (i.e., the groove portion 20) is less likely to be blocked by the weight of the person H to be treated who lies on the cushion portion 10, and thus, a defective supply of air to the air accumulation portion 60 can be prevented. Thus, warm air or cool air can be supplied to the inside of the ventilated mattress 1 while maintaining a comfortable sleeping feel.

Further, since the arrangement of the members such as the air supply hose can be omitted, the thickness of the pad 10 can be prevented, and the shape of the pad 10 can be designed more freely. For example, the pad 10 can be miniaturized. Thus, the ventilation mattress 1 can be miniaturized. Further, the pad 10 can be prevented from being locally hardened by the arrangement of the members such as the air supply hose, and thus the sleeping feel of the person H to be treated can be improved. In addition, the manufacturing cost of the ventilation mattress 1 can be reduced, and thus the productivity can be improved.

In the first embodiment, as described above, the air accumulation portion 60 has the through hole 30 and the airbag 40. The through hole 30 is disposed in the groove 20. The airbag 40 is connected to the through hole 30. With this configuration, for example, the balloon 40 itself can be raised and lowered by the supply of cool air or warm air, so that the treatment site of the person H to be treated can be cooled or heated and simultaneously the treatment can be performed by the balloon 40. Thus, the ventilation mattress 1 can perform treatment on the person H to be treated comfortably.

Preferably, the ventilation mattress 1 further includes a sensor 80 for detecting the temperature of the air accumulation unit 60 or the air supplied to the air accumulation unit 60. For example, the sensor 80 is disposed in the through hole 30. The detection result is output to the control unit 2e (see fig. 4A to 4C described later). The sensor 80 is a generic term for the sensors 81 to 86 described later. The present utility model is not limited to this example, and the sensor 80 may be disposed in the groove 20 or the airbag 40. Alternatively, it may be attached to the outer surface of the airbag 40.

Next, at least the upper layer 16 of the support plates 11, 12, 13 is a porous body having open cells. With this configuration, the cool air or warm air in the groove portion 20 and the air accumulation portion 60 is diffused into at least the upper layer portion 16 of the support plates 11, 12, 13 by the continuous air bubbles. Therefore, at least the entire upper layer 16 can be gradually warmed or cooled. Therefore, the side of the pad 10 on the therapy subject H can be cooled or heated appropriately. By diffusing the air supplied from the air supply device 2, it is also possible to dehumidify at least the inside of the upper layer 16 of the cushion 10 and the inside of the cushion 18 covering the cushion 10. Thus, the ventilation mattress 1 can provide a more comfortable sleeping feel to the person H to be treated.

For example, in the present embodiment, the upper layer portion 16 is formed of foamed polyurethane. The lower layer 15 is made of hard resin such as ABS or polypropylene, and is fixed to the upper layer 16 by a fixing member such as an adhesive or a screw. By forming the lower layer portion 15 with a hard resin, the groove portion 20 can be prevented from being deformed and blocked by the person H to be treated. However, the present utility model is not limited to this example, and the lower layer portion 15 may be formed of a porous body having open cells, such as foamed polyurethane, in the same manner as the upper layer portion 16.

In the present embodiment, the lower layer portion 15 and the upper layer portion 16 are separate members. However, the present utility model is not limited to this example, and the lower layer portion 15 and the upper layer portion 16 may be one member in at least one of the support plates 11, 12, and 13. In other words, the lower layer 15 and the upper layer 16 may be formed integrally and may be formed as a single member. In this case, the groove portion 20 of the lower layer portion 15 is formed as a passage portion provided in the support plates 11, 12, 13. The air accumulation unit 60 is disposed on the ventilation path and connected to the ventilation path. With this configuration, the number of components of the support plates 11, 12, 13 can be reduced, and therefore, the cost of the ventilation mattress 1 can be reduced, and the productivity can be improved.

Grooves 21 and 22 are formed in the lower layer 15 of the support plate 11. The upper layer 16 of the support plate 11 is formed with a through hole 31 provided in the groove 21 and a through hole 32 provided in the groove 22. The through-holes 31 and 32 communicating with the groove portions 21 and 22 are connected to the airbags 41 and 42 via joints (not shown). A sensor 81 for detecting the temperature of the air supplied to the air-facing portion 61 is disposed in the through hole 31. A sensor 82 for detecting the temperature of the air supplied to the air-facing portion 62 is disposed in the through hole 32. The detection results of the sensors 81 and 82 are output to the control unit 2e.

Grooves 23, 24 are formed in the lower layer 15 of the support plate 12. The upper layer 16 of the support plate 12 is formed with a through hole 33 provided in the groove 23 and a through hole 34 provided in the groove 24. The through-holes 33 and 34 communicating with the groove portions 23 and 24 are connected to the airbags 43 and 44 via joints (not shown), respectively. A sensor 83 for detecting the temperature of the air supplied to the air-facing portion 63 is disposed in the through hole 33. A sensor 84 for detecting the temperature of the air supplied to the air-facing portion 64 is disposed in the through hole 34. The detection results of the sensors 83 and 84 are output to the control unit 2e.

A groove 25 is formed in the lower layer 15 of the support plate 13. The upper layer portion 16 of the support plate 13 is formed with a through hole 35 and a through hole 36 disposed in the groove portion 25. The through hole 35 and the through hole 36 communicating with the groove 25 are connected to the air bags 45 and 46 via joints (not shown). The through holes 35 and 36 communicate with the common groove 25, but separate grooves may be provided for the through holes 35 and 36. A sensor 85 for detecting the temperature of the air supplied to the air-facing portion 65 is disposed in the through hole 35. A sensor 86 for detecting the temperature of the air supplied to the air-facing portion 66 is disposed in the through hole 36. The detection results of the sensors 85 and 86 are output to the control unit 2e.

The groove 20 is formed in a rectangular cross section, but may be formed in a shape having a curved inner wall surface (a semicircular cross section, etc.). The depth of the groove 20 is desirably about 5 to 10 mm. This prevents the strength of the support plates 11, 12, 13 from decreasing without blocking the air flow. In this case, the thickness of the lower layer 15 is desirably 10 to 20mm, and the thickness of the support plates 11, 12, 13 is desirably 15 to 40 mm.

Each support plate 11, 12, 13 has a connection portion 19. The connection portion 19 communicates with the groove portion 20 and is connected to the air supply device 2. Specifically, a plurality of connection portions 19 protruding from the pad portion 10 are attached to one side surface of the support plates 11, 12, 13. The connection portions 19 are connected to the corresponding groove portions 20, respectively, and connect the hoses 6 branched from the hose bundle 5. That is, the connection portion 19 connects the hoses 6 and the groove portion 20 to each other so as to be capable of flowing.

That is, the support plate 11 is provided with two connection portions 19 connected to the groove portions 21 and 22, respectively. The support plate 12 is provided with two connection portions 19 connected to the groove portions 23, 24, respectively. The support plate 13 is provided with a connection portion 19 connected to the groove portion 25. Thereby, the groove 20 connected to the air supply device 2 via the hoses 6 and the through holes 30 connected to the air bags 40 in the groove 20 form air passages, and air is supplied from the air supply device 2 to the air bags 40 via the groove 20 and the through holes 30. Therefore, the air flow path is not blocked by the person H to be treated who lies on the cushion portion 10, and the poor supply of air to the air bag 40 can be prevented, thereby improving the therapeutic effect. In addition, the airbag 40 and the cushion 10 can be miniaturized, and the ventilated mattress 1 can be miniaturized.

When the solenoid valves corresponding to the respective airbags 40 are opened to supply air from the air supply device 2, the airbags 40 are inflated as indicated by a one-dot chain line E (see fig. 2 and 3). The airbag 40 is contracted by venting when the corresponding solenoid valve is closed. The neck and shoulder of the person H lying on the cushion 10 are treated by the inflation and deflation of the air bags 41 and 42. The lumbar region of the person H lying on the cushion 10 is treated by the inflation and deflation of the air bags 43 and 44. The leg of the person H lying on the cushion 10 is treated by the inflation and deflation of the air bags 45 and 46.

At this time, the air flow path is formed by the groove portion 20 provided in the lower portion 15 and the through hole 30 provided in the upper portion 16 of the support plates 11, 12, 13, and thus the air flow path can be prevented from being crushed and blocked by the person H to be treated. Further, since the groove 20 can be disposed at the position of the cushion 10 where the person H to be treated is carried, the airbag 40 and the cushion 10 can be miniaturized.

< gas supply device 2>

Next, first to third configuration examples of the air supply device 2 will be described with reference to fig. 4A to 4C. Fig. 4A is a schematic diagram showing a first configuration example of the air supply device 2. Fig. 4B is a schematic diagram showing a second configuration example of the air supply device 2. Fig. 4C is a schematic diagram showing a third configuration example of the air supply device 2. In fig. 4A to 4C, only the connection portion 19 of any one of the support plates 11, 12, 13 is described for simplicity, and the description of the connection portion 19 of the other two of the support plates 11, 12, 13 is omitted.

< first structural example >

In fig. 4A, the air supply device 2 includes a cool air supply unit 2a for supplying cool air, a warm air supply unit 2b for supplying warm air, and a solenoid valve 2c. The solenoid valve 2c is disposed on each of the support plates 11, 12, 13, and connects one of the cool air supply unit 2a and the warm air supply unit 2b to one end of the groove 20. In detail, the tube bundle 5 includes a tube 6a through which cool air flows and a tube 6b through which warm air flows. One end of the hose 6a is connected to the cool air supply part 2a. One end of the hose 6b is connected to the warm air supply unit 2b. The other ends of the hoses 6a and 6b are branched for the respective connection portions 19 arranged on the support plates 11, 12, and 13, and are connected to the groove portions 20 via the solenoid valve 2c and the connection portions 19. The solenoid valve 2c is, for example, a three-way valve, and connects one of the hoses 6a and 6b to the groove 20. By switching the connection of the electromagnetic valve 2c, either cold air or warm air is supplied to the groove portion 20.

By independently operating the solenoid valves 2c, the support plates 11, 12, 13 can be cooled or heated independently. Therefore, the temperature of the different body parts of the person H to be treated lying directly above the different support plates 11, 12, 13 can be raised and lowered independently of each other. For example, the support plate 11 directly under the neck side of the person H to be treated can be cooled by the supply of cool air, and the support plate 13 directly under the leg side can be warmed by the supply of warm air. Thus, the ventilation mattress 1 can provide a more comfortable sleeping feel to the person H to be treated.

The air supply device 2 of the ventilation mattress 1 further includes an input unit 2d and a control unit 2e. The input unit 2d receives an operation input from the person H to be treated and transmits the operation input to the control unit 2e. For example, switching of on and off of the air supply device 2, a set temperature of air supplied to the air accumulation unit 60, and the like are input to the input unit 2 d. The control unit 2e controls the respective components of the air supply device 2 based on programs and data stored in a non-transitory storage medium (not shown), the detection result of the sensor 80, the operation input of the input unit 2d, and the like.

For example, the control unit 2e controls each solenoid valve 2c independently. Specifically, the control unit 2e switches the solenoid valves 2c based on the detection result of the sensor 80. For example, when the temperature detected by the sensor 81 is equal to or higher than the first threshold value, the hose 6a is connected to the tank 20 and cold air is supplied. On the other hand, if the detected temperature of the sensor 81 is equal to or lower than the second threshold value (which is smaller than the first threshold value), the hose 6b is connected to the groove portion 20, and warm air is supplied. The first threshold value and the second threshold value may be set based on an operation input of the input unit 2d, or may be preset data.

The control unit 2e adjusts the temperature of the air supplied from the cool air supply unit 2a and the warm air supply unit 2b based on the detection result of the sensor 80. For example, the temperature of the air supplied from the cool air supply unit 2a is adjusted according to an increase or decrease in the temperature difference between the first threshold value and the detected temperature of the sensor 81. The temperature of the air supplied from the warm air supply unit 2b is adjusted according to an increase or decrease in the temperature difference between the second threshold value and the detected temperature of the sensor 81. By adjusting the temperatures of the cool air and the warm air, the temperature of the air accumulation unit 60 can be automatically and appropriately adjusted.

Alternatively, the temperature control may be performed based on an operation input from the input unit 2 d. Alternatively, the temperature control may be performed in accordance with a predetermined program instead of the feedback control.

< second structural example >

Next, not limited to the above example, the cold air and the warm air may be simultaneously supplied to the same groove 20, and the temperature control may be performed according to the ratio of the flow rates of both. In fig. 4B, the air supply device 2 includes a cool air supply unit 2a for supplying cool air and a warm air supply unit 2B for supplying warm air. In addition, the air supply device 2 has an adjusting portion 2f instead of the solenoid valve 2c of fig. 4A. The adjusting portion 2f adjusts the amount of cold air and warm air supplied to the same groove portion 20. Specifically, the adjusting portion 2f is disposed for each of the connecting portions 19 of the support plates 11, 12, 13, and is independently controlled by the control portion 2e.

The adjusting portion 2f includes a first adjusting portion 2fa and a second adjusting portion 2fb. The first adjusting portion 2fa is disposed in the hose 6a, and adjusts the flow rate of the cool air in a range of 0 to 100% relative to the maximum flow rate. The second adjusting portion 2fb is disposed in the hose 6b, and adjusts the flow rate of warm air with respect to the maximum flow rate in a range of 0 to 100%.

For example, the other end of the hose 6a is connected to the same connection portion 19 of each support plate 11, 12, 13 via the first adjustment portion 2fa, and the other end of the hose 6b is connected via the second adjustment portion 2fb. Therefore, cool air and warm air can be supplied to the same groove portion 20. By adjusting the air volumes of both independently, the mixing ratio of both in the groove portion 20 changes. Therefore, the temperature of the air supplied to the groove portion 20 can be adjusted without changing the temperature of the cool air supplied from the cool air supply portion 2a and the temperature of the warm air supplied from the warm air supply portion 2b. Thus, the temperature of the air accumulation portion 60 can be adjusted, and thus the ventilation mattress 1 can provide a more comfortable sleeping feel to the person H to be treated.

The air supply device 2 of the ventilation mattress 1 further includes an input unit 2d and a control unit 2e. The control unit 2e controls the first adjusting unit 2fa and the second adjusting unit 2fb independently, for example. Specifically, the control unit 2e adjusts the ratio of cool air to warm air based on the detection result of the sensor 80. By adjusting the mixing ratio of the cool air and the warm air in this way, the temperature of the air accumulation unit 60 can be accurately adjusted. For example, if the detected temperature of the sensor 81 is equal to or higher than the first threshold value, at least one of an increase in the flow rate of cool air by the first adjusting unit 2fa and a decrease in the flow rate of warm air by the second adjusting unit 2fb is performed. Thereby, the temperature of the air accumulation unit 60 or the inside thereof is reduced. If the detected temperature of the sensor 81 is equal to or lower than the second threshold value (which is smaller than the first threshold value), at least one of the decrease in the flow rate of the cool air by the first adjusting portion 2fa and the increase in the flow rate of the warm air by the second adjusting portion 2fb is performed. Thereby, the temperature of the air accumulation unit 60 or the inside thereof is increased.

At this time, the control unit 2e may or may not adjust the temperature of the air supplied from the cool air supply unit 2a and the warm air supply unit 2b based on the detection result of the sensor 80. The temperature control described above may be performed based on an operation input from the input unit 2 d. Alternatively, the temperature control may be performed in accordance with a predetermined program instead of the feedback control. In the above-described configuration in which the temperature control is performed without using the sensor 80, the sensor 80 may be omitted.

< third structural example >

In the air supply device 2 of the first and second configuration examples, the temperature of each of the support plates 11, 12, 13 is independently controlled. However, the present utility model is not limited to this example, and the same temperature control may be performed on each of the support plates 11, 12, 13.

In fig. 4C, the air supply device 2 includes a cool air supply unit 2a for supplying cool air, a warm air supply unit 2b for supplying warm air, a solenoid valve 2C, an input unit 2d, and a control unit 2e. The solenoid valve 2c is disposed between the cool air supply unit 2a and the warm air supply unit 2b and the tube bundle 5, and connects either the cool air supply unit 2a or the warm air supply unit 2b to the tube bundle 5. That is, by switching the solenoid valve 2c, either cool air or warm air flows into the tube bundle 5 and is supplied to the groove portions 20 of the support plates 11, 12, 13. In this way, the ventilation mattress 1 capable of cooling or heating the air accumulation unit 60 and the support plates 11, 12, 13 can be realized with a simple structure.

< second embodiment >

Next, in the ventilated mattress 1, at least one airbag 40 may also be omitted. Fig. 5 is a plan view showing a ventilation mattress 1 according to a second embodiment of the present utility model. Fig. 6 shows a C-C cross-sectional view of fig. 5. In fig. 5, as an example, the entire airbag 40 is omitted. For convenience of explanation, the same reference numerals are given to the same parts as those of the first embodiment shown in fig. 1 to 3.

In the second embodiment, the air accumulation portion 60 is a space formed inside the upper layer portion 16. The air accumulation portion 60 is disposed directly above the groove portion 20 and connected to the groove portion 20. In this way, cold air or warm air can be stored in advance in the air accumulation unit 60, and therefore the body part of the person to be treated directly above the air accumulation unit 60 can be cooled or heated particularly intensively.

Preferably, the air accumulation portion 60 is a hollow container 70 disposed in the upper layer portion 16. The hollow vessel 70 is harder than the upper layer 16. An opening 70a is formed in the bottom surface of the hollow container 70. The hollow container 70 is connected to the groove portion 20 through the opening 70a. The hollow container 70 is a generic term for hollow containers 71 to 76 described later. The opening 70a is a generic term for the openings 71a to 76a described later. The air accumulation portion 60 is formed of a hard resin such as polypropylene, for example. In this way, deformation of the air accumulation portion 60 due to the body weight of the person H to be treated can be suppressed or prevented. Accordingly, sinking of the body part directly above the air accumulation portion 60 can be suppressed or prevented. The illustration does not exclude the structure in which the air-accumulating portion 60 does not have the hollow container 70, and the hollow container 70 is softer than the upper layer portion 16. For example, the air accumulation portion 60 may be formed of a resin having flexibility, such as silicone.

Further, the hollow container 70 may be formed with a single hole or a plurality of holes 70b other than the opening 70a. The hole 70b penetrates the wall of the hollow container 70 and communicates the inside with the outside. It is further preferable that the hole 70b is formed at the upper plate of the hollow container 70. The hole 70b is a generic term for a hole (not shown) formed in the hollow vessel 70 of the support plate 11, a hole (not shown) formed in the hollow vessel 70 of the support plate 12, and holes 75b, 76b (see fig. 6) formed in the hollow vessel 70 of the support plate 13. Thus, since air leaks from the hollow container 70 through the hole 70b into the upper layer portion 16, the vicinity of the air accumulation portion 60 (for example, immediately above the air accumulation portion) can be cooled or heated particularly intensively. However, this example does not exclude a structure in which the hole 70b is formed in the hollow container 70 other than the upper plate (for example, a side plate, etc.), or a structure in which the hole 70b is not formed in the hollow container 70 other than the opening 70a.

For example, the gas accumulating portions 61 and 62 are disposed on the support plate 11. The air accumulation portion 61 is constituted by a hollow container 71 disposed in the support plate 11 on the groove portion 21, and communicates with the groove portion 21 through an opening 71a in the bottom of the hollow container 71. The air accumulation portion 62 is constituted by a hollow container 72 disposed in the support plate 11 on the groove portion 22, and communicates with the groove portion 22 through an opening 72a in the bottom of the hollow container 72. Preferably, at least the upper plate of the hollow containers 71, 72 is provided with a hole 70b. By supplying cool air or warm air to the air accumulation portions 61 and 62, for example, the neck of the person to be treated H can be intensively cooled or heated.

Further, the support plate 12 is provided with air accumulating portions 63 and 64. The air accumulation portion 63 is constituted by a hollow container 73 disposed in the support plate 12 on the groove portion 23, and communicates with the groove portion 23 through an opening 73a in the bottom of the hollow container 73. The air accumulation portion 64 is constituted by a hollow container 74 disposed in the support plate 12 on the groove portion 24, and communicates with the groove portion 24 through an opening 74a in the bottom of the hollow container 74. Preferably, at least the upper plate of the hollow containers 73, 74 is provided with the hole 70b. By supplying cool air or warm air to the air accumulation portions 63 and 64, for example, the trunk portion of the person to be treated H can be intensively cooled or heated.

Further, the support plate 13 is provided with air accumulating portions 65 and 66. The air accumulation portion 65 is constituted by a hollow container 75 disposed in the support plate 13 on the groove portion 25, and communicates with the groove portion 25 through an opening 75a in the bottom of the hollow container 75. The air accumulation portion 66 is constituted by a hollow container 76 disposed in the support plate 13 on the groove portion 25, and communicates with the groove portion 25 through an opening 76a in the bottom of the hollow container 76. Preferably, at least the upper plate of the hollow containers 75, 76 is provided with the hole 70b. By supplying cool air or warm air to the air accumulation portions 65 and 66, for example, the lower leg portion of the person to be treated H can be intensively cooled or warmed.

< third embodiment >

Next, a third embodiment will be described with reference to fig. 7 and 8. Fig. 7 shows a top view of the ventilation mattress 1 of the third embodiment. Fig. 8 shows a D-D cross-sectional view of fig. 7. For convenience of explanation, the same reference numerals are given to the same parts as those of the first and second embodiments shown in fig. 1 to 6.

In the present embodiment, the connection portion 19 is omitted from the support plates 11 and 13 and is provided only in the support plate 12, compared with the first embodiment. The grooves 21, 22, 25 are provided separately. That is, the air supply device 2 is connected to the groove portion 20 of one support plate 12. The other portions are the same as the first embodiment.

The hose bundle 5 led out from the air supply device 2 is connected to a connection portion 19 provided to the support plate 12. Each groove 20 is connected to the connecting portion 19.

The groove 21 communicating with the air bag 41 is divided into a groove 21b formed in the support plate 11 and a groove 21a formed in the support plate 12. The groove 22 communicating with the air bag 42 is divided into a groove 22b formed in the support plate 11 and a groove 22a formed in the support plate 12. The groove 25 communicating with the air cells 45 and 46 is divided into a groove 25a formed in the support plate 12 and a groove 25b formed in the support plate 13. Grooves 23, 24 communicating with the air cells 43, 44 are formed in the support plate 12, respectively.

The groove portions 21b and 21a of the support plates 11 and 12 disposed adjacently are connected by a flexible pipe 17. A cavity 18b in which the damper 18 is not provided is provided in the connecting portion 18a between the support plates 11, 12. The length of the piping 17 is longer than the distance between the grooves 21b and 21a provided in the support plates 11 and 12 provided adjacently. Therefore, the pipe 17 is disposed in a bent state in the cavity 18b.

Similarly, the groove portions 22b and 22a of the support plates 11 and 12 disposed adjacently are connected by the flexible pipe 17. The length of the piping 17 is longer than the distance between the grooves 22b and 22a provided in the support plates 11 and 12 provided adjacently. Therefore, the pipe 17 is disposed in a bent state in the cavity 18b between the support plates 11, 12.

Similarly, the groove portions 25a and 25b of the support plates 12 and 13 disposed adjacently are connected by the flexible pipe 17. A cavity 18b in which the damper 18 is not provided is provided in the connecting portion 18a between the support plates 12, 13. The length of the piping 17 is longer than the distance between the grooves 25a and 25b provided in the support plates 12 and 13 provided adjacently. Therefore, the pipe 17 is disposed in a bent state in the cavity 18b between the support plates 12, 13. The plurality of pipes 17 may be disposed in one cavity 18b, or the cavities 18b may be provided for the respective pipes 17.

Thus, the pipe 17 is not bent at a steep angle when the pad 10 is folded over the connecting portion 18a, and damage to the pipe 17 can be prevented even if the pad is repeatedly folded.

According to the present embodiment, as in the first embodiment, the air flow path is not blocked by the person H to be treated who lies on the cushion portion 10, and the poor supply of air to the air bag 40 can be prevented, thereby improving the treatment effect. In addition, the airbag 40 and the cushion 10 can be miniaturized, and the ventilated mattress 1 can be miniaturized.

The plurality of support plates 11, 12, 13 are disposed in parallel so as to be bendable by the connection portion 18a, and a cavity 18b in which the pipe 17 connecting the groove portions 21b, 21a of the support plates 11, 12 disposed adjacently is disposed between the support plates 11, 12 disposed adjacently is disposed in a state of being deflected. This prevents damage to the pipe 17 when the mat 10 is repeatedly folded, and prevents a defect in air supply and exhaust caused by damage to the pipe 17.

< fourth embodiment >

Next, a fourth embodiment will be described with reference to fig. 9 and 10. Fig. 9 shows a top view of a fourth embodiment of a ventilated mattress. Fig. 10 shows a sectional view of E-E of fig. 9.
