PURPOSE:To prevent the generation of a decubitus by connecting the space parts of respective mats constituted by bonding the peripheral edges of soft sheets and forming the parts enclosed with the peripheral edges on the inner and outer sides of endless curvilinear lines by line adhesion to a liquid forcing pump via a rotary valve. CONSTITUTION:The mat bodies A to E are formed into hemming parts 2 by previously bonding the peripheral edges of two sheets of upper and lower soft sheets and are connected to each other by line adhesion of the inside surfaces of the upper and lower sheets enclosed with the hemming parts 2 in the form of the endless curvilinear lines to form the spaces (a) enclosed by the endless curvilinear lines and the spaces (b) sandwiched by the outer side of the endless curvilinear lines and the inner side of the hemming parts 2; thereafter, fluid inlet/outlet pipes 3a, 3b communicating with the spaces (a), (b) are installed to the mat bodies. These mats A to E are constituted by integrally connecting all of the respective fluid inlet/outlet pipes 3a, 3b to a rotary valve 5 so that the spaces (a), (b) are alternately bulged at specified periods by the fluid, such as compressed air or warm water, sent from the pump P. |
