Patent ID: 7985376

Claim:
A disposable measuring unit used in an analyzer for counting particles in a plurality of blood samples, comprising: a first plate being composed of a transparent resin; a second plate being combined with the first plate and composed of a transparent resin; 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 first pressure introduction port for introducing a pressure to mix the quantified sample and the diluent agent so as to prepare the diluted sample; a measuring section comprising an electrical characteristic measuring section for counting particles in the diluted sample, the electrical characteristic measuring section comprising a channel for passage of the diluted sample and two electrodes exposed to the channel, and a second pressure introduction port for introducing a pressure to transport the diluted sample to the measuring section, wherein the diluent container, the channel, the first pressure introduction port and the second pressure introduction port are formed by the first and second plates, wherein the disposable measuring unit is detachably connectable to an analyzer, and the pressure being supplied to the first and second pressure introduction ports by the analyzer, wherein the pressure is supplied to the first and second pressure introduction ports by the analyzer, wherein the disposable measuring unit is removed from the analyzer and is discarded with respect to each blood sample.
