Smear staining apparatus, smear preparing apparatus, smear processing system, and method for determining staining condition

摘要

A smear staining apparatus comprising: a staining section which stains a smear sample with a quantity of stain fluid; and a controller, wherein the controller: receives information regarding a stain state on a smear sample which is stained according to a first staining condition by the staining section; and determines a second staining condition on the basis of the information and a target value which defines a targeted stain state, is disclosed. A smear preparing apparatus, a smear processing system and method for determining staining condition are also disclosed.

1. A smear staining apparatus comprising:
a staining section comprising a stain fluid preparing unit for preparing a stain fluid by mixing a concentrated stain fluid and a diluting fluid and a supplying unit for supplying a smear sample with the prepared stain fluid to stain the smear sample; and a controller, wherein the controller:
receives information indicating a density of stain of a smear sample which is stained according to a first staining condition by the staining section, the information being calculated from a plurality of color densities of a nucleus of a plurality of white blood cells in the smear sample stained according to the first condition;determines a second staining condition on the basis of the information and a target value which defines a predetermined targeted density of the stain, andcontrols the staining section such that the stain fluid is prepared under the second staining condition, and wherein the determining of the second staining condition comprises:
adjusting a mixing ratio of the first staining condition to increase the proportion of the concentrated stain fluid when the density of stain of the smear sample indicated by the information is lighter than the predetermined targeted density, andadjusting the mixing ratio of the first staining condition to decrease the proportion of the concentrated stain fluid when the density of stain of the smear sample indicated by the information is darker than the predetermined targeted density.
