Abstract:
1. A positive pressure chamber for extremities comprising: a bag-shaped member having a bag-shaped main part which is formed to inflate a space part defined by an exterior sheet member and an interior sheet member with fluid, said bag-shaped member being formed in such shape and size that, under a condition in which it is filled with fluid, it can cover the outer periphery of at least one of the extremities; wherein said bag-shaped member is formed such that, when the space part is filled with the fluid, said extremity which is entirely covered with said interior sheet member is held under a positive pressure condition, and the distal end of said extremity can be moved in said space part, independently of other parts of the extremity; and wherein said interior sheet member has an inlet, on the extremity's distal end side, for introducing the fluid that has been filled in the bag-shaped member and/or other fluid onto the outer periphery of the extremity and allows the fluid that is introduced therefrom to flow along a clearance between the outer periphery of the extremity and said interior sheet member in a direction away from the extremity's distal end; and said positive pressure chamber, further comprising: a clearance securing member for securing said clearance for the fluid to flow between the outer periphery of said extremity and said interior sheet member.
