Abstract

A slide holder is disclosed which is suitable for use in an automated differential blood cell classifier. The molded plastic holder provides a readily identifiable, stackable, and nestable device for protectively handling, positioning, and transporting a specimen such as a film of blood to be analyzed.

Claims

1. A slide holder for accommodating a planar specimen slide which comprises:

(a) a molded frame to accommodate said slide;

(b) integral cooperating slide holding means for retaining said slide defined by said frame;

(c) nesting means defined by opposing sides of said frame to cooperate with corresponding nesting means of vertically stacked adjacent slide holders to permit movement of one slide holder in one direction while preventing movement in a direction substantially transverse thereto; and

,

(d) transport means operatively associated with said frame to permit mechanical transfer of said slide holder.

2. A slide holder according to claim 1 wherein said frame includes an encoding area.

3. A slide holder according to claim 2 wherein said encoding area is machine readable.

4. A slide holder according to claim 2 wherein said encoding area is human readable.

5. A slide holder according to claim 1 wherein said frame can accommodate a glass planar specimen slide.

6. A slide holder according to claim 1 wherein said frame can accommodate a plastic planar specimen slide.

7. A slide holder according to claim 1 wherein said integral cooperating slide holding means includes a resilient biasing means.

8. A specimen holder which comprises:

(a) a planar specimen slide;

(b) a molded frame to accommodate said slide;

(c) integral cooperating slide holding means for retaining said slide in said frame;

(d) nesting means defined by opposing sides of said frame to cooperate with corresponding nesting means of vertically stacked adjacent specimen holders constructed in a range to permit movement of one slide holder in one direction while preventing movement in a direction substantially transverse thereto; and

,

(e) transport means operatively associated with said frame to permit mechanical transfer of said specimen holder.

9. A specimen holder which comprises:

(a) an integral planar specimen slide;

(b) a frame encompassing said slide;

(c) nesting means defined by opposing sides of said frame to cooperate with corresponding nesting means of vertically stacked adjacent specimen holders to permit movement of one slide holder in one direction while preventing movement in a direction substantially transverse thereto; and

,

(d) transport means operatively associated with said frame to permit mechanical transfer of said specimen holder.
