Abstract
A blood component collection cassette has a flow path in the interior thereof through which blood flows, and a cassette main body composed of a resin that possesses flexibility. The cassette main body includes a first constituent part in which a plurality of concavities and convexities are formed. Furthermore, a resin sheet includes a second constituent part, which is provided on one portion of an outer surface of the flow path wall portion that constitutes the flow path, and in which the plurality of concavities and convexities do not exist.
Claims19
A biological component collection cassette having a flow path in an interior of the cassette through which a liquid containing at least one biological component flows, comprising:
- a cassette main body composed of a resin that possesses flexibility;
- wherein the cassette main body includes a first constituent part constituted from an outer surface having a plurality of concavities and convexities, and a second constituent part constituted from an outer surface on which the plurality of concavities and convexities do not exist;
- and
- the second constituent part is provided on at least a part of a flow path wall portion that constitutes the flow path.

A biological component collection system comprising:
- a biological component collection kit including a tube, and a biological component collection cassette communicating with the tube, and having a flow path in an interior of the cassette through which a liquid containing at least one biological component flows;
- a biological component separation device to which the biological component collection kit is attached, and through which the biological component contained within the liquid is allowed to flow;
- wherein the biological component collection cassette comprises a cassette main body composed of a resin that possesses flexibility;
- the cassette main body includes a first constituent part constituted from an outer surface having a plurality of concavities and convexities, and a second constituent part constituted from an outer surface on which the plurality of concavities and convexities do not exist;
- and
- the second constituent part is provided on at least a part of a flow path wall portion that constitutes the flow path;
- the biological component separation device includes a cassette mounting unit in which the biological component collection cassette is mounted;
- and
- the cassette mounting unit includes a detection unit adapted to detect a state of the liquid at a position facing toward the second constituent part.
A method of manufacturing a biological component collection cassette having a flow path in an interior of the cassette through which a liquid containing at least one biological component flows, comprising:
- a sheet supplying step of supplying a resin sheet having a first constituent part constituted from an outer surface having a plurality of concavities and convexities;
- a non-irregular part forming step of forming a second constituent part on which the plurality of concavities and convexities are eliminated from a predetermined position of the resin sheet, by applying heat to the predetermined position of the resin sheet which is supplied by the sheet supplying step;
- and
- a cassette forming step of forming the biological component collection cassette, by after the non-irregular part forming step, sealing the resin sheet while securing the flow path in the cassette.
