PROBLEM TO BE SOLVED: To flatten a structure, and to prevent stress to the body by forming the specific number of compressible chambers connected via a check valve and respectively provided with connecting bodies in the shape of being deviated in an opening state. SOLUTION: At least two circular chambers 10, 11 are juxtaposed in an almost 8 shape, and an artificial bladder is formed of an elastic plastic material, particularly, a silicon material excellently allowable by the body. Bow-shaped upper walls 12, 13 are arranged in a projecting surface shape in both chambers 10, 11. A wall thickness of the chamber 11 is formed thicker than a wall thickness of the chamber 10 to obtain a strong sucking effect. The bottom of both chambers 10, 11 is formed of annexed thin plate walls 14, 15, both chambers 10, 11 are sealed, and are formed in the shape of being deviated in an opening state as a whole. Both chambers 10, 11 are connected by a check valve 23, and connecting bodies 16, 20 for connecting external hoses 18, 22 having check valves 17, 21 are arranged on the upper walls 12, 13. Then, an artificial bladder can be embedded without applying stress, and applicability to a body tissue can be improved. |
