DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, wherein like numerals indicate like elements, there is shown in FIG. 1 a specimen transport apparatus 10 in accordance with the present invention. The specimen transport apparatus includes a rectangular block of foam material 12. The foam material comprising block 12 may be any suitable foam material, but preferably is comprised of a high density foam material and particularly high density polyether foam. High density foam material provides enhanced protection for the vials being shipped within the transport apparatus. Other high density foam materials may be utilized.
The rectangular block of foam material 12 is provided with a plurality of elongated receptacles such as those indicated at 14, 16 and 18. The elongated nature of the receptacles is best illustrated in FIG. 2, and particularly see elongated receptacle 16 shown therein. The receptacles are arranged in a grid formation in two orthogonal directions as illustrated in FIG. 1. Each of the elongated receptacles is provided with a foam extension extending into the receptacle from a receptacle wall. As illustrated in FIG. 1, the foam extension is preferably triangular in cross section. For example, elongated receptacle 14 is provided with foam extension 24 with a cross sectional shape of a triangle, elongated receptacle 16 is provided with foam extension 26 in the cross sectional shape of a triangle and elongated receptacle 18 is provided with foam extension 28 in the form of a triangle in cross section. Each elongated receptacle is adapted to receive a vial for a specimen, which in many cases will be a biological specimen being shipped for testing or the like. As illustrated in FIG. 1, vial 20 is about to be inserted into receptacle 16.
In FIG. 2, vial 20 is shown as being inserted within receptacle 16 and is firmly held in place by partially compressed foam extension 26.
Referring back to FIG. 1, rectangular foam block 12 is contained within a box 30. Box 30 is provided with different indicia thereon in two orthogonal directions for identifying each receptacle whereby a vial in any receptacle may be identified. More particularly, as illustrated in FIG. 1, in a first orthogonal direction there is illustrated the letters A through F, indicated by the numeral 32. The letters A through F are alphabetical indicia identifying each of six columns of receptacles. Along a second orthogonal direction, box 30 is marked with numerical indicia 1 through 6 identified by the numeral 34. Each numeral identifies a particular row. In this manner, any particular receptacle, and more particular any particular vial in a particular receptacle, may be identified by an alpha numeric designation. For example, a vial placed in the first row of the first column would be identified as A1. Vial 20 would be identified by the alpha numeric designation of D6. In this manner, a list may be transported with the specimen transport apparatus or may be otherwise communicated from the sender to the receiver, such as by fax or e-mail, identifying each vial contained within the transport apparatus by an alpha numeric designator. For example, if vial 20 is the blood of John Doe, this may be identified as vial D6 containing the blood of John Doe. The recipient in this manner can easily, quickly and efficiently select any particular vial by its positive identification.
As illustrated in FIG. 2, specimen transport apparatus of the present invention would typically be shipped with an absorbing layer of material 36 surrounding it and an outer sealed plastic bag or container 38. Absorbing material 36 and outer plastic bag or container 38 are shown in dotted outline form in FIG. 2.
Referring now to FIG. 3, there is shown a broken away portion of box 30 with receptacles 40 and 42 containing vials 44 and 46, respectively. Vials 44 and 46 are shown in dotted outline form. Compressing the triangular shaped foam extensions 48 and 50, respectively. Foam extensions 48 and 50 firmly hold the vials in place. It is understand that the foam extensions need not be triangular shaped, although a triangular shaped foam extension is a presently preferred embodiment. Other various shapes of material may be utilized to extend into the normally square space of the receptacle.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of the invention.
