When 5) is full, tension is generated in the lateral direction (both sides),
Even the portion of the mattress without the air bag is configured to levitate the human body 200 and generate a force to disperse the weight.

As shown in FIG. 1, the supply / exhaust pipes 37 of the two main buoyancy bags 24 and 25 are connected to a control device 53 via pipes 51 and 52, respectively, and two auxiliary bladders are also provided. Three
The air supply / exhaust pipes 42 of 9 and 40 are connected to a control device 53 via pipes 54 and 55, and the control device 53 is connected to an air pump 57 driven by a motor 56. , The air pump 57 is a housing 58
It is stored inside.

The operation of the above embodiment will now be described, the use of which is shown schematically in FIG.
The spread body 10 is spread and placed in the substantially central portion of the mattress 59, and the straps 49 and 50 and the surface fasteners 47 and 48 on both sides are placed.
The mattress 59 is wound around and fixed to the mattress 59, and the mattress 60 is laid and set on the mat body 10. Next, the air pump 57 and the control device 5 via the drive of the motor 56.
By the operation of 3, air is sent to the two sub-bags 39, 40,
The auxiliary air bags 39 and 40 are inflated. This side air bag 39, 40
The patient 200 is laid on its side in an inflated state. In this state, the internal pressure of the sub air bags 39, 40 is automatically 25 m / m in the mercury column due to the action of the minute air holes 46. Then, the main buoyancy bags 24, 25 are driven by the operation of the air pump 57 and the control device 53 via the drive of the motor 56.
If the patient is inflated to either one of the
00 is pushed up and tilted as shown in FIG. At this time, if the internal pressure of the main buoyancy bladders 24 (or 25) is 10 m / m or less in the mercury column, it does not expand sufficiently and hits the patient 200 softly, but a sufficient turnover angle θ cannot be obtained. About 20 to 25 m / m is suitable for the mercury column, but when the center line of the patient 200 (the suture line 13 shown in FIG. 1) is a straight line, only a part of the epidermis of the patient 200 is passed through the litter 60. In particular, between the shoulder blades of both sides, the boneless abdomen between the ribs and hipbone (the hip bone), the inside of the thigh, etc., there is tenderness because it pushes up parts that are not heavy with normal bedding, so that good sleeping comfort is achieved. Although not obtained, the two main buoyancy bladders 24, 25 have a welding line 30 between both scapulae and a welding line 31 of the abdominal part in an arc shape as shown in FIGS. 1 and 4. Moreover, since the welding lines 33 on the thighs are formed in a curved shape, the pressing force on these portions is reduced, and good sleeping comfort is obtained.

In order to obtain a strong turn-over angle, it is sufficient to increase the internal pressure of the main buoyancy bags 24 and 25, but on the other hand, the sleeping comfort becomes worse. Therefore, by utilizing the property that the smaller the diameter when inflated even with the same internal pressure, the easier it is to be crushed by the external pressure, as shown in FIG. An auxiliary air bag 61 is provided on the upper surface, and the force that pushes up the patient 200 is the main air bag 24 (or 25).
The soft feeling of the patient's 200 skin is obtained by the auxiliary air bag 61. To further explain, the auxiliary air bag 61 includes an auxiliary air bag body 62 and an outer bag 63, as shown in FIGS.

Further, within each division, along the vertical welding lines 71 and 72. The continuous inflation / deflation air bag portions 73, 74 are formed by welding and the air bag chambers 69, 7 are formed.
On the upper surface of the innermost inflation / deflation bag portions 73 and 74 at 0,
Minute squirt holes 75, 76 are formed at appropriate intervals at each symmetrical position, and air supply / exhaust pipes 77, 78 are provided at the lower ends of the air bag chambers 69, 70, respectively. The auxiliary air bag body 62 is a cloth outer bag having sheet fasteners 79 and 80 that engage with sheet fasteners 81 on the upper surface of the floor covering body 10 in the vertical direction on both sides of the surface facing the upper surface of the floor cloth body 10. It is stored and locked in 63. Therefore, in the auxiliary air bag 61 configured in this way, both sides of the auxiliary air bag 61 are engaged and locked by the sheet fasteners 81 and 80 by the sheet fasteners 79 and 80, respectively. The supply / exhaust pipes 77, 78 are superposed on the upper surfaces of the storage units 20, 21, and the main levitation air is supplied via the pipes 82, 83 and solenoid valves 84, 85, as schematically shown in FIG. Air supply / exhaust pipe 3 for bags 24 and 25
7 pipes 51 and 52 are connected. In this manner, the patient 200 is laid sideways upward with the auxiliary air bags 39 and 40 inflated at all times, and in this state, either one of the main levitation bags 24 (or 25) and the auxiliary air bags The inflation / deflation bag 73 (or 74) of one of the bag chambers 69 (or 70) of the bag 61 is inflated at the same time, and the patient 20
The main levitating bag 24 (or 25) is used to lift 0
If the expansion and contraction air bag portions 73 (or 74) of the auxiliary air bag 61 are used to compensate for the soft feeling on the patient's skin, the fumes from the minute air holes 75 (or 76) of the auxiliary air bag 61 will be generated. The internal pressure of the auxiliary air bag chamber 69 (or 70) is automatically adjusted, and even if there is a half down time, it is possible to sufficiently dry the skin of the patient and the mattress which the rabbit is easily wet. According to the experiment, the turning angle (θ) of 30 degrees or more could be obtained without impairing the sleeping comfort.

The portions of the main buoyancy bags 24 and 25 corresponding to the legs of the human body 200 (the welding lines 14 and 15) are formed to be narrow in order to prevent pressure on the thighs. In addition, the auxiliary air bags 39 and 40 have an effect of preventing lateral displacement of the patient 200 and receiving and dispersing the weight of the patient 200 as shown by a solid arrow in FIG. The mattress 59 is secured to both sides of the mattress 59 only when the main and sub air bags are inflated and the position is higher than the upper surface of the mattress 59.
This is to prevent the generation of wrinkles which may be a cause of bed sores when the tension acts on 0, discharges air, shrinks and returns to the original flat state.

There are various symptoms of the patient, and there are cases where the patient cannot turn over in one direction, and there is a case where he / she needs to be laid sideways for a long time in a certain posture without turning over immediately after the operation. In some cases, it may be better to start the procedure so that the device can be turned over only in one direction, that is, left (right) tilt → upward position → left (right) tilt or upward direction. In addition to being incorporated in the control position 53 so that it can be placed only in the position, in order to move and change the part that supports the weight when the player is in the upward position, instead of the auxiliary air bag 61 or by placing it on top of it, A bag 86 is attached.
