Reagent cartridge

摘要

A reagent cartridge which can be exchangeably inserted into an analyzer and having a plurality of reagent bags furnished with connecting lines, each of which may optionally be connected to an input device of the analyzer, and method for operating the analyzer are disclosed. Each reagent bag has an analyzer-controlled multi-way valve with at least two valve positions at the point where the respective connecting line departs, such that the first valve position opens a fluid path between the connecting line and the reagent bag, while the second valve position closes off the reagent bag and opens a fluid path between a ventilation source, e.g. ambient air, and the connecting line. The connecting lines of the reagent bags departing from the multi-way valve open directly into a common rail or a collector valve.

1. A reagent cartridge, which is exchangeably insertable into an analyzer having an input device and a ventilation source, said reagent cartridge comprising a plurality of flexible reagent bags, each of said reagent bags having a peripheral seam and being furnished with an analyzer-controlled multi-way valve, said multi-way valve comprises a valve housing which is connected directly to and extends within the reagent bag, wherein a connecting line departs directly from said valve housing which is connectable to the input device of the analyzer, wherein each analyzer-controlled multi-way valve has at least two valve positions, wherein a first valve position opens a fluid path between the connecting line and the reagent bag, and a second valve position closes off the reagent bag and opens a fluid path between the ventilation source and the connecting line, wherein the multi-way valve is heat-sealed or glued into the peripheral seam of the reagent bag.
