1. A body fluid component separating device comprising:
a housing comprising a container and a lid that define a space sealed against the outside;
a piston configured to divide the sealed space of the housing into a first space and a second space and to fluidly connect the first space and the second space;
a manipulator configured to adjust a movement of the piston between a first location in which the first space has a first volume and a second location in which the first space has a second volume different from the first volume, and configured to fix the piston at an arbitrary location between the first location and the second location, the manipulator being operably coupled to the piston; and
a filter structure configured to fluidly connect the first space and the second space and to filter a fluid flowing from the first space to the second space,
wherein the body fluid component separating device is configured to maintain the pressure balance between the first space and the second space such that when the piston descends, a pressure of the first space increases, and a pressure of the second space decreases regardless of an external force that causes the piston to move downward,
wherein the manipulator comprises:
a shaft having a longitudinal axis;
a male engagement element formed on the shaft;
a female engagement element engaged with the male engagement element and fixedly installed to the piston;
a handle comprising a first engagement member; and
a second engagement member connected to the shaft and engaged with the first engagement member,
wherein when the manipulator is not operated by the male engagement element, the female engagement element, handle, and the second engagement member, the manipulator fixes a position of the piston with respect to the housing, and wherein the lid comprises a piston guide configured to guide a movement of the piston, and
wherein the filter structure comprises:
a filter housing having an inlet port fluidly connected to the first space, a first outlet port fluidly connected to the second space, and a second outlet port fluidly connected to the second space and disposed opposite the first outlet port;
a first filter installed in the first outlet port; and
a second filter installed in the second outlet port.
