Abstract

A medical slide holder for use in medical procedures including automated microscopy. The slide holder comprises a rectangular frame adapted for receiving slides of differing thicknesses. Compensation for differing thicknesses is achieved through the disposition of two fastening caps, one for each end of the slides, the caps having resilient extending fingers which contact upper surfaces of the slides near their ends. Precision positioning of the slides within the holder is facilitated through provision of slide-supporting ledges having partitions to define positions of the slides; and precision positioning of the holder frame is facilitated through the provision of angled corners and notches each having a right angle and an obtuse angle. The slide holder has a recessed indentation in both the upper and lower locking caps to facilitate their removal once engaged to the frame, thus allowing slide specimens to be removed from the slide carrier for archiving purposes. Upon their removal, tangs internal to the frame'"'"'s locking receptables are intentionally damaged thus preventing the frame from being re-used and preventing contamination of future slide specimens due to slide carrier re-use.

Claims

1. A medical slide holder comprising:

(a) a rectangular frame defining a rectangular opening therewithin;

said rectangular frame including

(i) a pair of opposite sides each having a proximal and a distal end;

(ii) a front member bridging between distal ends of said opposite sides and rigidly interconnected therewith; and

(iii) a rear member bridging between proximal ends of said opposite sides and rigidly interconnected therewith;

said front member having a front ledge extending inwardly therefrom at a lower extremity of said front member; and

said rear member having a rear ledge extending inwardly therefrom at a lower extremity of said rear member, said front and said rear ledges having slide-engaging surfaces for supporting specimen slides,

(b) a first locking cap having an upper surface and a lower surface with a first plurality of resilient fingers protruding outwardly from said lower surface;

means for fastening said first locking cap to said front member to project said first plurality of resilient fingers toward said front ledge thereby to resiliently engage upper surfaces of slides when said slides are positioned in said slide holder; and

(c) a second locking cap having an upper surface and a lower surface with a second plurality of resilient fingers protruding outwardly from said lower surface;

said second locking cap including means for fastening said second locking cap to said rear member to project said second plurality of resilient fingers toward said rear ledge thereby to resiliently engage upper surfaces of slides when said slides are positioned in said slide holder.

2. The medical slide holder according to claim 1 wherein, when said first locking cap and said second locking cap are locked respectively to said front and said rear members, said resilient fingers project downwardly toward said front and rear ledges.

3. The medical slide holder according to claim 1 wherein said front and said rear ledges include at their slide-engaging surfaces a plurality of spaced protrusions defining positions for said slides.

4. The medical slide holder according to claim 3 in which said spaced protrusions are partition barriers.

5. The medical slide holder according to claim 1 wherein said first locking cap when fastened to said front member extends over said front ledge.

6. The medical slide holder according to claim 1 wherein said second locking cap when fastened to said rear member extends over said rear ledge.

7. The medical slide holder according to claim 1 wherein said first locking cap when fastened to said front member extends over said front ledge and wherein said second locking cap when fastened to said rear member extends over said rear ledge.

8. The medical slide holder according to claim 1 in which said first locking cap is an elongated strip.

9. The medical slide holder according to claim 1 in which said second locking cap is an elongated strip.

10. The medical slide holder according to claim 1 in which said first locking cap is a first elongated strip and in which said second locking cap is a second elongated strip.

11. The medical slide holder according to claim 1 wherein said sides are of non uniform-thickness.

12. The medical slide holder according to claim 11 wherein said non-uniform thickness is manifested in that regions of said sides at said proximal and distal ends are thicker than regions intermediate said proximal and distal ends.

13. The medical slide holder according to claim 1 wherein said front member includes two ends with a first corner at one of said ends and a second corner at the second of said ends, one of said corners having a position defining taper to ensure correct orientation of said slide holder when said slide holder is positioned for processing.

14. The medical slide holder according to claim 1 wherein said front member includes at its outer periphery a plurality of notches for precisely positioning said slide holder into a predetermined position.

15. The medical slide holder according to claim 14 wherein said notches are spaced longitudinally along said outer periphery of said front member.

16. The medical slide holder according to claim 15 wherein said notches are tapered.

17. The medical slide holder according to claim 1 wherein said first and said second locking caps each include recessed indentation means for separating said upper and said lower locking caps from said frame when said first and said second locking caps are locked to said frame.
