Abstract
A flow path device of a biological component bag system is equipped with a device main body. The device main body includes a first sheet and a second sheet, and flow paths are formed between the first sheet and the second sheet. The flow paths include a first flow path, a second flow path, a filter accommodating chamber, and a third flow path. In the device main body, flow path sealed portions that join the first sheet and the second sheet to each other in a liquid-tight manner are disposed along the flow paths.
Claims18
A flow path device in which there are formed flow paths configured to allow at least one liquid of a biological fluid and a medicinal solution to flow therethrough, the flow path device comprising:
- a device main body comprising:
- a first sheet formed by a soft material;
- and
- a second sheet formed by a soft material and that is superimposed on the first sheet, wherein the device main body comprises a first portion including:
- a plurality of first flow paths;
- a plurality of first ports at a first edge of the first portion and in communication with the plurality of first flow paths;
- a single second flow path configured to communicate with the plurality of first flow paths;
- and
- a second port in communication with the single second flow path and at a second edge of the first portion opposite the first edge;
- a filter accommodating chamber provided in the single second flow path and in which there is accommodated a filter member configured to remove a predetermined biological component in the biological fluid;
- and
- a third flow path through which the liquid having passed through the filter accommodating chamber flows;
- wherein flow path sealed portions, which are configured to join the first sheet and the second sheet to each other in a liquid-tight manner, are provided in the device main body.
A flow path device in which there are formed flow paths configured to allow at least one liquid of a biological fluid and a medicinal solution to flow therethrough, the flow path device comprising:
- a device main body in which there are provided sealed portions configured to mutually join a plurality of sheets formed by a soft material in a liquid-tight manner to thereby form the flow paths in an interior of the sheets;
- wherein the device main body comprises a first main body portion, a second main body portion, and a connecting part configured to connect the first main body portion and the second main body portion;
- the first main body portion comprising:
- a plurality of first flow paths;
- a plurality of first ports at a first edge of the first main body portion and in communication with the plurality of first flow paths;
- a second flow path in communication with the plurality of first flow paths;
- and
- a second port in communication with the second flow path and at a second edge of the first main body portion opposite the first edge;
- the second main body portion comprising:
- a filter accommodating chamber provided in the second flow path and in which there is accommodated a filter member configured to remove a predetermined biological component in the biological fluid;
- and
- a third flow path through which the liquid having passed through the filter accommodating chamber flows;
- wherein the connecting part forms at least a portion of the second flow path between the second port and the second main body portion.
A biological component bag system configured to collect a desired biological component from a biological fluid, the biological component bag system comprising:
- a plurality of first bags in which the biological fluid is accommodated;
- a flow path device to which the plurality of first bags are connected;
- and
- a second bag configured to accommodate the biological component which is guided from the plurality of first bags via the flow path device;
- wherein the flow path device comprises a device main body configured to allow at least one liquid of the biological fluid and a medicinal solution to flow therethrough;
- the device main body comprising:
- a first sheet formed by a soft material;
- and
- a second sheet formed by a soft material and that is superimposed on the first sheet;
- wherein the device main body comprises a first portion including:
- a plurality of first flow paths;
- a plurality of first ports at a first edge of the first portion and in communication with the plurality of first flow paths;
- a second flow path configured to communicate with the plurality of first flow paths;
- and
- a second port in communication with the second flow path and at a second edge of the first portion opposite the first edge;
- a filter accommodating chamber provided in the second flow path and in which there is accommodated a filter member configured to remove a predetermined biological component in the biological fluid;
- and
- a third flow path through which the liquid having passed through the filter accommodating chamber flows;
- wherein flow path sealed portions, which are configured to join the first sheet and the second sheet to each other in a liquid-tight manner, are provided in the device main body.
