Abstract

The invention relates inter alia to an automated stainer for staining, in particular for hemalum-eosin (HE) staining, of a histological sample, the automated stainer exposing the sample to the action of at least one stain using at least one staining parameter. The automated stainer is notable for the fact that the automated stainer comprises an input means with which a staining parameter is definable, in particular is inputtable or is selectable from a plurality of possible staining parameters; and that a control apparatus is present which, upon application of the defined staining parameter, ascertains the prospectively expectable outcome of an action and displays it to the user with a display apparatus, before the automated stainer actually stains the sample.

First claim

What is claimed is:

1. An automated stainer for staining, in particular for hemalum-eosin (HE) staining, of a histological sample, the automated stainer exposing the sample to the action of at least one stain using at least one staining parameter, wherein the automated stainer comprises:
an input apparatus with which a staining parameter is defined by a user or selected from a plurality of possible staining parameters; and
a control apparatus which, upon definition or selection of the staining parameter, is configured to ascertain a prospective expected outcome of an action of the staining parameter and display the prospective expected outcome to the user with a display apparatus before the automated stainer stains the sample.

2. The automated stainer according to claim 1 , wherein the display apparatus comprises a touch-sensitive screen.

3. The automated stainer according to claim 1 , wherein the input apparatus comprises a touch-sensitive screen.

4. The automated stainer according to claim 1 , wherein the control apparatus retrieves the prospective expected outcome from a memory storing at least one of:
(i) a plurality of expected outcomes;
(ii) a plurality of expected outcomes, the staining parameter or a combination of the staining parameters being stored in association with each of the plurality of expected outcomes; and
(iii) a plurality of expected outcomes, at least one sample property being stored in association with each of the plurality of expected outcomes.

5. The automated stainer according to claim 1 , further comprising an image acquisition apparatus which generates a synoptic image of the sample by at least one of optical scanning of the sample, dark-field illumination of the sample, and use of a phase contrast method, wherein the control apparatus displays the prospective expected outcome on the basis of the generated synoptic image.

6. The automated stainer according to claim 1 , wherein the control apparatus displays the prospective expected outcome in the form of an exemplary view of an exemplary sample different from the sample.

7. The automated stainer according to claim 1 , wherein the staining parameter relates to at least one of an age of the stain; a chemical composition of the stain; a duration of action of the stain; and a quantitative ratio of several stains.

8. A staining kit, in particular a hemalum-eosin (HE) staining kit, wherein the staining kit comprises:
a medium configured to store a plurality of staining parameters;
an input apparatus with which one of the plurality of staining parameters is selected; and
a control apparatus which, upon selection of the staining parameter, is configured to ascertain a prospective expected outcome of an action of the staining parameter and display it to a user with a display apparatus before actually staining a sample.
