Abstract
A measuring unit includes a quantifying section for quantifying a sample in volume, a main channel communicating with the quantifying section, an analyzing section provided in the main channel for analyzing the quantified sample, and a pressure introduction port communicating with the main channel for introducing a pressure into the main channel to transport the sample from the quantifying section to the analyzing section, wherein the analyzing section comprises at least one of an electrical characteristic measuring section for measuring an electrical characteristic of the sample and an optical characteristic measuring section for measuring an optical characteristic of the sample.
Claims24
A disposable measuring unit used in an analyzer for counting particles in a blood sample, comprising:
- a quantifying section for quantifying a blood sample in volume;
- a diluent agent for diluting the quantified sample;
- a diluent container for containing the diluent agent;
- a measuring section for measuring the diluted sample by the diluent agent;
- a first pressure introduction port for introducing a pressure to mix the quantified sample and the diluent agent so as to prepare the diluted sample, and
- a second pressure introduction port for introducing a pressure to transport the diluted sample to the measuring section,
- wherein the measuring section comprises an electrical characteristic measuring section for counting particles in the diluted sample, the disposable measuring unit being detachably connectable to an analyzer, and the pressure being supplied to the first and second pressure introduction ports by the analyzer.
A measuring unit comprising,
- an electrical resistance measuring section for measuring an electrical resistance of a sample,
- wherein the electrical resistance measuring section is detachably connected to an analyzer having a constant direct current source and a signal processing section.
