DETAILED DESCRIPTION OF PRESENTLY PREFERRED EMBODIMENTS
Referring to FIG. 1, the presently preferred embodiment of the slide holder comprises a substantially rectangular body member 20 disposed with its longitudinal axis substantially vertical. In an alternative embodiment, the body member 20 may be disposed with its longitudinal axis substantially horizontal. The body member 20 comprises a front wall 10, first side wall 40 connected to the front wall 10, a back wall 30 connected to the first side wall 40, a second side wall 50 connected to the back wall 30 and a bottom wall 60 connected to the back wall 30, the first side wall 40 and the second side wall 50. The front wall 10 and back wall 30 each have at least one hole 80 and the bottom wall has at least one hole 70. In an alternative embodiment, the front wall 10 may be open. In yet another alternative embodiment, the back wall 30 may be open. The front wall 10, the first side wall 40, the second side wall 50 and the bottom wall 60 are fabricated with guide means 90, such as ribs, slots, guides or the like. An optional handle 100 is affixed to the body member 20 and the optional handle 100 is preferably affixed to the back wall 30.
FIG. 2 shows a side view of the slide holder including optional handle 100, particularly illustrating the guide means 90, such as ribs, slots, guides or the like. In the presently preferred embodiment, the optional handle 100 is preferably affixed to the back wall 30 by a tack weld.
FIG. 3 shows a back view of the slide holder including optional handle 100, illustrating the guide means 90 and the back wall 30 having at least one hole 80.
FIG. 4 shows a top view of the slide holder including optional handle 100, particularly illustrating the bottom wall 60 having at least one hole 70, together with guide means 90.
FIG. 5 shows details of the guide means 90 in the presently preferred embodiment in which the guide means 90 are preferably ribs.
In the presently preferred embodiment, the body member 20 is fabricated from a plastic material and the optional handle 100 is fabricated from a metal material. In alternative embodiments, the body member 20 and optional handle 100 may each be fabricated from a plastic material, a metal material, or any suitable material within the skill in the art. In the presently preferred embodiment, the plastic material is at least one of polypropylene, nylon, polyethylene, fiber glass reinforced plastic and poly vinyl chloride (PVC), or the like and, the metal material is at least one of stainless steel, chrome alloy steel, aluminum T6T4, or the like. In the presently preferred embodiment, the optional handle 100 is affixed to the body member 20 by a tack weld, or the like.
In the presently preferred embodiment, to accommodate currently available microscope slides, the body member 20 is of height about 2.375 inch and the back wall 30 has three holes 80. Two of the holes 80 are substantially circular of diameter about 0.625 inch, with centers substantially disposed on the vertical midline of the back wall 30 at depth 0.9 and 1.8 inch, respectively. The third hole 80 is of substantially horizontal oval shape, of height about 0.125 inch and center substantially disposed on the vertical midline of the back wall 30 at depth about 0.3 inch.
In the presently preferred embodiment, the optional handle 100 is fabricated to a height of about 2.24 inch with a linear portion disposed substantially vertically and an arcuate portion with radius of curvature about 0.5 inch. The optional handle 100 is affixed to the back wall 30 by a tack weld or the like, extending about 0.375 inch above the body member 20.
In the presently preferred embodiment, the bottom wall 60 has two holes 70. Each hole is substantially circular, of diameter about 0.063 inch and the centers are substantially equidistant and substantially disposed on the horizontal midline of the bottom wall 60.
In the presently preferred embodiment, the guide means 90, such as ribs, slots, guides or the like, are corrugated of width about 0.07 inch to accommodate currently available microscope slides and the guide means 90 are spaced by about 0.05 inch to substantially prevent contact between the faces of successively inserted slides and likewise substantially permit contact between the inserted slides and side walls 40 and 50.
In operation, microscope slides containing specimens disposed in specimen zones are inserted into the guide means 90 such that the specimen zones are substantially completely disposed within the body member 20 when the slides are fully inserted. In an exemplary embodiment, the specimens comprise biological specimens. The slide holder, optionally held by the optional handle 100 is then submerged in a staining liquid to a depth sufficient to substantially completely cover the specimen zones and then withdrawn from the staining liquid when the staining process is substantially complete. The slide holder is designed to provide advantages including that microscope slides inserted into the guide means will substantially remain inside the slide holder when the slide holder is submerged in a staining liquid, the staining liquid will maintain substantial contact with microscope slides inserted into the slide holder and, substantially all the staining liquid will drain from the slide holder when the slide holder is withdrawn from the staining liquid.
Whereas particular embodiments of the present invention have been described above for purposes of illustration, it will be evident to those skilled in the art that numerous variations of the details may be made with departing from the invention as defined by the appended claims.
