Cassette and system component insertable into a centrifuge in cooperation with the cassette

摘要

The invention pertains to a cassette (2) comprising a product conveying path (1, 1a, 1b) and a shut-off device (19a, 19b) integrated into the cassette for interrupting a product flow. The shut-off device is arranged at a rim of the cassette such that the shut-off device (19a, 19b) can be directly operated manually and/or mechanically. The product-conveying path (1, 1a, 1b) leads through the shut-off device (19a, 19b). The cassette consists of a lower part (5) and an upper part (7) which are connectable to each other by connecting means (9, 11, 13, 15).

主权项

1. A system component for being arranged in a centrifuge having a rotor rotatable around a hub for separating blood components, wherein the system component comprises:
an operating means formed by an arrangement of at least two levers adapted to operate a shut-off device of a cassette, wherein the operating means has a first centrally arranged lever having an end that can be directly moved by a first piston or indirectly moved by a second lever, wherein said end has a longer stroke if moved by said first piston than if moved by said second lever.
