(Operation) Claims 1 to 5 configured as described above.
The operation of the invention described in 1) will be explained below together with its use. A predetermined number of air cells in the transverse direction on a flat base sheet, adjacent to each other, by means of attachment / detachment such as male and female hooks,
The air chambers of the air cell group are connected to the air supply tubes, which are detachably attached to each series, on different side edges of the base sheet and along the side edges of the base sheet through a T-shaped connector. Next, the two air supply tubes arranged along the both side edges are connected to a common air supply source. Using the mat of the present invention assembled in this manner, when it is desired to turn over a patient such as a bedridden elderly person or a user, for example, from a common air supply source through one air supply tube to the air cell group of each system When air is supplied alternately, the air cells of one system swell first, the air cells of the other system remain flat, and the air chambers of each air cell in the one system that supplied air are located on the same side of the base sheet. Since the ends are formed wide, they become thick, and the other side of the mat swells thinly because the width of the air chamber is narrowed, and the mat as a whole swells on one side and thinly on the other side. Next, the air in one system to which air was previously supplied is exhausted from the air chambers of the air cell group, and the air is supplied to the air chambers of the air cell groups in the other system in the same manner as the previous time. The group bulges into a thickness shape that is the opposite of the last time. By repeating such operations and alternately inflating and deflating the two series of air cell groups, the postures of the patient and the user on the mat are changed and the patient is turned over. When air is supplied to both air systems, all the air chambers of the air cell group in all of the mat swell, and as a whole, both sides of the mat are thick and the center swells slightly from the bedside to the feet. During use, any air cell may be damaged causing air leakage.
Supply of compressed air to the air cell group
Then remove only this damaged air cell from the base sheet.
Replace it with a new one, and reuse. Particularly, in the invention described in claim 2, since the width of the narrow end of each of the air chambers is formed wider than that of the most narrowed portion, the air chamber group of one system is formed. Even when only the air is supplied, the thin tip of each air chamber also bulges slightly thicker. In the invention described in claim 3, since the width of the thicker end of each air chamber is 1.5 to 4 times the width of the thinnest part, air is supplied to only one system. Even when the mat surface is inclined, the inclination angle does not become steep, the sleeping comfort is not deteriorated, and the mat is safe. Particularly, in the invention described in claim 4, since Excel is molded by the composite material, it withstands high air. Particularly, in the invention described in claim 5, since the air cell comprises a rubber tube covered with a cloth bag, liquid such as water or hot water is supplied to and discharged from the air cell by using an underwater pump instead of the air. Then, the air cell is expanded and contracted.
