Abstract

The present disclosure relates to a contact protection apparatus for covering connection point(s) of a medical fluid-conducting cassette used for a medical treatment. The contact protection apparatus includes at least one covering section for covering the connection point before the use of the cassette, and at least one connection section for detachably connecting the contact protection apparatus or for holding the contact protection apparatus on the cassette. It further relates to a medical fluid-conducting cassette with a contact protection apparatus.

First claim

The invention claimed is:

1. A contact protection apparatus for covering a connection point of a medical fluid-conducting cassette for a medical fluid treatment, the contact protection apparatus comprising:
a first side,
a second side opposite the first side,
at least one covering section for covering the connection point before use of the medical fluid-conducting cassette,
a first connection section configured to detachably connect the contact protection apparatus to or hold the contact protection apparatus on the medical fluid-conducting cassette, the first connection section comprising an insert or plug-in connection or part thereof; and
a second connection section configured to detachably connect the contact protection apparatus to or hold the contact protection apparatus on the medical fluid-conducting cassette, the second connection section comprising a projection configured to be inserted into a centering opening of the medical fluid-conducting cassette.

2. The contact protection apparatus according to claim 1 , wherein the at least one covering section comprises a first structure projecting from the second side of the contact protection apparatus, wherein the first structure has a closed circumference.

3. The contact protection apparatus according to claim 2 , wherein the at least one covering section comprises a second structure projecting from the second side of the contact protection apparatus, wherein the second structure has a closed circumference.

4. The contact protection apparatus according to claim 1 , further comprising a grip section, wherein the grip section comprises a structure projecting from the second side of the contact protection apparatus, wherein the structure has a closed circumference.

5. The contact protection apparatus according to claim 4 , wherein the structure of the grip section comprises at least one recess in an outer edge of the structure.

6. The contact protection apparatus according to claim 1 , wherein the second connection section comprises a structure projecting from the second side of the contact protection apparatus, wherein the structure has a closed circumference.

7. The contact protection apparatus according to claim 6 , wherein the structure of the second connection section comprises a recess in an outer edge of the structure.

8. The contact protection apparatus according to claim 1 , wherein a grip section is arranged between the first connection section and the second connection section.

9. The contact protection apparatus according to claim 1 , wherein the contact protection apparatus comprises a first through-opening in an area of the second connection section.

10. The contact protection apparatus according to claim 1 , wherein the contact protection apparatus comprises a spacer in an area of the first connection section.

11. The contact protection apparatus according to claim 1 further comprising an encoding structure for an arrangement which is encoded on the medical fluid-conducting cassette according to a shape of the contact protection apparatus.

12. The contact protection apparatus according to claim 1 , further comprising a fixing device for detachably receiving or retaining inlet and outlet tubes of the medical fluid-conducting cassette or for detachably receiving or retaining inlet or outlet tubes of the medical fluid-conducting cassette.

13. The contact protection apparatus according to claim 12 , wherein the fixing device is arranged only on one side of the contact protection apparatus.

14. The contact protection apparatus according to claim 13 , wherein the at least one covering section is separate from a grip section.

15. The contact protection apparatus according to claim 1 , wherein the contact protection apparatus is produced unitarily as a one-piece apparatus.

16. A medical fluid-conducting cassette system, comprising:
a medical fluid-conducting cassette; and
a contact protection apparatus comprising:
a first side,
a second side opposite the first side,
at least one covering section for covering a connection point of the medical fluid-conducting cassette before use of the medical fluid-conducting cassette,
a first connection section configured to detachably connect the contact protection apparatus to or hold the contact protection apparatus on the medical fluid-conducting cassette, the first connection section comprising an insert or plug-in connection or part thereof, and
a second connection section configured to detachably connect the contact protection apparatus to or hold the contact protection apparatus on the medical fluid-conducting cassette, the second connection section comprising a projection configured to be inserted into a centering opening of the medical fluid-conducting cassette.

17. The medical fluid-conducting cassette system according to claim 16 , wherein the contact protection apparatus is attached to the medical fluid-conducting cassette without any adhesives.

18. The medical fluid-conducting cassette system according to claim 16 , wherein the contact protection apparatus comprises a section that protrudes from an edge of the medical fluid-conducting cassette.

19. The medical fluid-conducting cassette system according to claim 18 , wherein a grip section of the contact protection apparatus is arranged on the section that protrudes from the edge of the medical fluid-conducting cassette.

20. The medical fluid-conducting cassette system according to claim 16 , wherein the first connection section of the contact protection apparatus mechanically prevents the medical fluid-conducting cassette from being mounted to a blood treatment apparatus.

21. The medical fluid-conducting cassette system according to claim 16 , wherein the first connection section of the contact protection apparatus connects the contact protection apparatus to a retaining opening or the centering opening of the medical fluid-conducting cassette for intake of the medical fluid-conducting cassette at a blood treatment apparatus.

22. The medical fluid-conducting cassette system according to claim 16 , wherein the contact protection apparatus is configured to be sterilized with the medical fluid-conducting cassette.

23. The medical fluid-conducting cassette system according to claim 22 , wherein the at least one covering section of the contact protection apparatus is manually detachable from the medical fluid-conducting cassette.

24. The medical fluid-conducting cassette system according to claim 22 , wherein the at least one covering section of the contact protection apparatus is manually detachable from the connection point.

25. The medical fluid-conducting cassette system according to claim 16 further comprising:
an encoding structure on the medical fluid-conducting cassette that is shaped to correspond to a shape of the contact protection apparatus; and
an edge contour that corresponds to a contour of the encoding structure of the contact protection apparatus.

26. The medical fluid-conducting cassette system according to claim 16 , wherein at least one connection point is a fluid fitting for a substituate line.

27. The medical fluid-conducting cassette system according to claim 16 , wherein the medical fluid-conducting cassette is a blood cassette.

28. The medical fluid-conducting cassette system according to claim 16 , wherein a depth of the centering opening of the medical fluid-conducting
