There are issues such as No. 0159. The integral structure shown in these figures has a shape in which a relatively hard, non-flexible molded body with a curved surface is laminated with a substantially flat flexible film, and the space formed between the two is bonded together. It includes various functional parts, such as a pump part, a body fluid conduction part, a filter part, a pressure measurement part, a valve part, and a blood storage part.
