Abstract
A pressure bag (1) includes: a pressing chamber (2) adapted to be inflated by air-feeding; and a rectangular outer layer (3) having such length as to surround the pressing chamber (2). Fasteners (35, 36) are formed on one end side of a front surface and the other end side of a back surface of shorter sides of the outer layer (3). The pressing chamber (2) is fixed to the outer layer (3) in the axial direction. In use, infusion bags (40, 41) are surrounded by the outer layer (3) in a manner contacting with the pressing chamber (2) and fastened by the fasteners (35, 36).
