Problems solved by technology

[0008] (2) if Figure 5 As shown, in the cross-section of the width direction of the air cushion between the welded parts A and B, that is, the Z-Z direction, the first bag-shaped body 1 has a relatively flat surface, so that the frictional force added to the Z direction is also large, and it will cause friction with the Z-Z direction. The same problem as in (1) above

Embodiment Construction

[0029] Figure 6-8 Air cushion 5 is shown in . A total of four flexible rectangular sheets, the first to fourth sheet materials 6, 7, 8, 9 are stacked in sequence and bonded to each other along the periphery to form a sealed structure with three spaces.

[0030] The first and second sheets 6 and 7 are bonded in point form by the first bonding portion 10 . A plurality of such first bonding portions 10 are provided at predetermined intervals along a straight line in the vertical and horizontal directions. The arrangement of this first bonding portion 10 has the relation that forms quadrilateral 12 (shown by dot-dash line) with adjacent 4 first bonding portions 10, promptly has to make the first bonding portion 10 be located in the corner of quadrangle 12 Relationship. The quadrilateral 12 is preferably a square, but may also be a rectangle. A first air chamber 13 is formed between the first and second sheets 6,7.

[0031] The second and third sheet materials 7 and 8 are bon...

Abstract

A three-tier structure consisting of first, second and third air cells 13, 15 and 17 is formed by stacking up first, second, third and fourth sheets 6, 7, 8 and 9 and sticking them to each other via spots. First adhesion parts 10 sticking the first and second sheets together are arranged at predetermined intervals, and adjacent four first adhesion parts are positioned in the corners of a rectangle. On the other hand, each of second adhesion parts 14 sticking the second and third sheets together is positioned in the center of the rectangle formed of the adjacent four first adhesion parts. The third air cell is constructed in the same way as the first air cell. An air pressure of the third air cell is kept at a high pressure, while air pressures of the first and second air cells are set to be low. A bedsore can be prevented by utilizing the low-pressure air mat preventing.

Description

technical field [0001] The present invention relates to an air mattress for treating, preventing or alleviating bedsores. Background technique [0002] The elderly who often lie down and the patients in long-term recuperation are prone to bed sores. Bed sores cause congestion, causing necrosis of tissue, when the pressure in the portion to which the patient's weight is particularly applied exceeds the blood flow obstruction pressure of the peripheral capillaries within the portion. [0003] To prevent such decubitus ulcers, an air cushion that lowers the air pressure in the air chamber below the blood flow obstruction pressure of peripheral capillaries has been proposed (JP-A-7-51325). [0004] This prior art air cushion such as figure 1 As shown, the whole becomes a bed-like rectangle. Then, the second bag-shaped body 2 made of flexible sheet material with a smaller surface area is placed in the first bag-shaped body 1 formed by the flexible sheet material. This second ...
