Claim 0:
1. A biological component collection device configured to be attachable to a separation device equipped with a first load detector, the biological component collection device comprising:
a cassette body comprising:
a flow path through which liquid flows, the flow path including a first branch and a second branch that is spaced apart from the first branch in a first direction on a surface of the cassette body;
a first port at a first end of the cassette body, wherein the liquid enters or exits the cassette body through the first port;
a first coupling member adjacent to the first port at the first end of the cassette body and that connects the first port, the first branch, and the second branch;
a second port at a second end of the cassette body opposite the first end, wherein the liquid enters or exits the cassette body through the second port;
a second coupling member adjacent to the second port at the second end of the cassette body and that connects the second port, the first branch, and the second branch, wherein the first branch and the second branch are spaced apart from one another along a length of the surface of the cassette body that corresponds to a distance between the first coupling member and the second coupling member;
a first soft portion in the first branch of the flow path, and which is pressable by the first load detector of the separation device; and
a second soft portion in the second branch of the flow path, wherein the second soft portion is more easily deformable than the first soft portion, and is pressable by a second load detector.
