Abstract

An apparatus for applying information to a medical slide or histology cassette has an ink jet printer for printing a printing medium directly onto the slide or cassette. The printing medium or the ink is placed onto the slide or cassette so that the resulting printed data is impervious against removal or damage during subsequent handling or treatment of the slide or cassette.

Claims

1. A method for applying information to a medical slide or histology cassette, comprising:

transporting a slide or histology cassette onto which data is to be printed from a storage means to a printing station;

printing directly onto a surface portion of a said slide or histology cassette to define an organised array of printed data using a printing medium, wherein the printed data is sealed onto said surface portion of the slide or histology cassette so that said organised array of printed data is proof against removal or damage during subsequent handling or treatment of the slide or histology cassette; and

transporting the slide or histology cassette onto which data has been printed from the printing station to a separate discharge location.

2. A method according to claim 1, wherein the printing medium comprises at least a solvent and a vinyl resin.

3. A method according to claim 1, wherein the printing medium is directly sealed to said surface portion of the slide or histology cassette.

4. A method according to claim 3, wherein the printing medium comprises at least a solvent and a vinyl resin.

5. A method according to claim 1, wherein the printing medium is sealed to said surface portion of the slide or cassette by applying a coating agent to said surface portion of the slide or histology cassette so as to cover said organised array of printed data.

6. A method according to claim 1, wherein the printing medium is an aqueous-based ink which is then coated with an immiscible coating agent.

7. A method according to claim 1, wherein the printing medium comprises a solvent.

8. A method for applying information to a medical slide or histology cassette according to claim 1, wherein said information is applied prior to use, comprising:

transporting a slide or histology cassette onto which data is to be printed from a storage means to a printing station, wherein said slide or histology cassette does not contain a specimen;

printing directly onto a surface portion of said slide or histology cassette to define an organised array of printed data using a printing medium, wherein the printed data is sealed onto said surface portion of the slide or histology cassette so that said organised array of printed data is proof against removal or damage during subsequent handling or treatment of the slide; and

transporting the slide or histology cassette onto which data has been printed from the printing station to a discharge location.

9. A method according to claim 8, wherein the printing medium is directly sealed to said surface portion of the slide or histology cassette.

10. A method according to claim 8, wherein the printing medium is sealed to said surface portion of the slide or cassette by applying a coating agent to said surface portion of the slide or histology cassette so as to cover said organised array of printed data.

11. A method according to claim 8, wherein the printing medium is an aqueous-based ink which is then coated with an immiscible coating agent.

12. A method for applying information to both medical slides and histology cassettes, comprising:

transporting a slide onto which data is to be printed from a storage means to a printing station;

printing directly onto a surface portion of said slide to define an organised array of printed data using a printing medium, wherein the printed data is sealed onto said surface portion of the slide so that said organised array of printed data is proof against removal or damage during subsequent handling or treatment of the slide;

transporting the slide onto which data has been printed from the printing station to a discharge location;

transporting a histology cassette onto which data is to be printed from a storage means to a printing station;

printing directly onto a surface portion of said cassette to define an organised array of printed data using a printing medium, wherein the printed data is sealed onto said surface portion of the cassette so that said organised array of printed data is proof against removal or damage during subsequent handling or treatment of the cassette;

transporting the histology cassette onto which data has been printed from the printing station to a discharge location.

13. A method according to claim 12, wherein the printing medium is directly sealed to said surface portion of the slide or histology cassette.

14. A method according to claim 12, wherein the printing medium is sealed to said surface portion of the slide or cassette by applying a coating agent to said surface portion of the slide or histology cassette so as to cover said organised array of printed data.

15. A method according to claim 12, wherein the printing medium is an aqueous-based ink which is then coated with an immiscible coating agent.

16. A method for applying information to both medical slides and histology cassettes prior to use, comprising:

transporting a slide onto which data is to be printed from a storage means to a printing station, wherein said slide does not contain a specimen;

printing directly onto a surface portion of said slide to define an organised array of printed data using a printing medium, wherein the printed data is sealed onto said surface portion of the slide so that said organised array of printed data is proof against removal or damage during subsequent handling or treatment of the slide;

transporting the slide onto which data has been printed from the printing station to a discharge location;

transporting a histology cassette onto which data is to be printed from a storage means to a printing station, wherein said histology cassette does not contain a specimen;

printing directly onto a surface portion of said cassette to define an organised array of printed data using a printing medium, wherein the printed data is sealed onto said surface portion of the cassette so that said organised array of printed data is proof against removal or damage during subsequent handling or treatment of the cassette;

transporting the histology cassette onto which data has been printed from the printing station to a discharge location.

17. A method according to claim 16, wherein the printing medium is directly sealed to said surface portion of the slide or histology cassette.

18. A method according to claim 16, wherein the printing medium is sealed to said surface portion of the slide or cassette by applying a coating agent to said surface portion of the slide or histology cassette so as to cover said organised array of printed data.

19. A method according to claim 16, wherein the printing medium is an aqueous-based ink which is then coated with an immiscible coating agent.
