Cartridge for stirring and dispensing a fluid, automatic analyzer and method of analyzing a biological sample

摘要

The invention relates to a cartridge 100 for dispensing a fluid, wherein the cartridge comprises:
- a reservoir chamber 102 operable for receiving the fluid 104, the reservoir chamber having a fluid outlet 106, wherein the reservoir chamber further comprises a cover 108 with a first bearing 110;
- a stirring assembly comprising a stirrer 114 located inside the reservoir chamber, the stirring assembly further comprising a shaft 112, the shaft being connected to the stirrer, the shaft further being located at least partially inside the reservoir chamber;
the stirring assembly being adapted to be moved between a first position and a second position, wherein in the first position the stirring assembly is operable to seal the fluid outlet 106, the stirring assembly in the first position further being operable to form a second bearing 111 with the reservoir chamber 102 or the fluid outlet 106 such that the stirrer 114 can be rotated about an axis 120 defined by the first 110 and second bearing 111 and wherein if the stirring assembly is in the second position the fluid 104 can pass through the fluid outlet 106, the shaft being adapted to transmit rotational power to the stirrer.
