Abstract

A sterilizable instrument cassette for use in storage and sterilization of medical and dental instruments includes two individual storage trays with base plates carrying silicone instrument-locating rails, and rotatable clamping members provided with silicone compression rails. The two trays may be separated or assembled and latched together, while the rotatable clamping member may be latched in its closed position. Multiple functions are performed by unitary structures simply and economically formed from single sheets of metal by stamping and bending.

Claims

1. A sterilization and storage cassette comprising:

first and second trays connectable with each other, wherein each of said trays has at least one instrument locating rail, wherein each of said at least one rail has first and second ends, and first and second rotatable clamping members wherein each of said members is affixed to a said respective tray at first and second pivot points adjacent to said ends and wherein each of said rotatable clamping members is independently rotatable relative to its respective tray about an axis that extends parallel to said at least one rail from a secured position to an open position.

2. A sterilization and storage cassette in accordance with claim 1 which includes a hinge connection between said trays.

3. A sterilization and storage cassette in accordance with claim 1 wherein each of said trays includes a plurality of said instrument locating rails.

4. A sterilization and storage cassette in accordance with claim 1 wherein said instrument locating rails are detachable from their respective trays.

5. A sterilization and storage cassette in accordance with claim 1 wherein each of said rotatable clamping members includes a compression rail.

6. A sterilization and storage cassette in accordance with claim 1 wherein said rotatable clamping members are detachable from their respective trays.

7. A sterilization and storage cassette in accordance with claim 1 wherein each of said trays has a plurality of fluid passage openings.

8. A sterilization and storage cassette in accordance with claim 1 wherein each of said trays has a plurality of stacking feet and stacking receptors.

9. A sterilizable instrument cassette comprising:

a pair of cassette components including at least one tray;

a hinge to join said tray and said other cassette component together to form said cassette;

a rail defining a plurality of instrument storage positions in said tray said rail having first and second ends;

a clamping member; and

mounting means for rotatably attaching said clamping member to said tray at first and second spaced apart locations adjacent to said ends, wherein said clamping member is rotatable about an axis that extends parallel to said rail into and out of a position for clamping instruments in place in said storage positions.

10. A sterilizable instrument cassette in accordance with claim 9 wherein said other cassette component is a second tray, and further comprising:

a second rail in said second tray defining a plurality of instrument storage positions therein;

a second clamping member; and

mounting means for rotatably attaching said second clamping member to said second tray, wherein said second clamping member is rotatable about an axis that extends parallel to said second rail into and out of a position for clamping instruments in place in said storage positions.

11. A sterilizable instrument cassette comprising:

a pair of cassette components including first and second trays;

a hinge to join said trays together to form said cassette;

elongate means for defining a plurality of spaced apart instrument positions in each of said trays;

clamping means in each of said trays; and

first and second mounting means rotatably attaching said clamping means to each of said trays, wherein said mounting means each includes first and second spaced apart elongated support members coupled to said clamping means and wherein each of said clamping means is rotatable about an axis that extends parallel to said elongated means into and out of an instrument clamping position.

12. A sterilizable instrument cassette in accordance with claim 11 wherein said means to define a plurality of spaced apart instrument positions includes an instrument locating rail.

13. A sterilization and storage cassette comprising:

a tray and a cover connectable to each other, wherein said tray has an elongated instrument locating rail with first and second ends and a rotatable clamping member affixed to said tray at two spaced apart pivot points adjacent to said ends, and wherein said rotatable clamping member is independently rotatable relative to said tray about an longitudinal axis that extends parallel to said rail from a secured position to an open position.

14. A cassette in accordance with claim 13 which includes a hinge connection between said tray and said cover.

15. A cassette as in claim 13 wherein said cover includes a second tray.

16. A cassette in accordance with claim 15 wherein each of said trays includes a plurality of said instrument locating rails.

17. A cassette in accordance with claim 16 wherein said instrument locating rails are detachable from their respective trays.

18. A cassette in accordance with claim 13 wherein each of said rotatable clamping members includes a compressible rail.

19. A cassette in accordance with claim 13 wherein said rotatable clamping member is detachable from said tray.

20. A cassette as in claim 13 wherein said clamping member is U-shaped.
