Tracking biological and other samples using RFID tags
First Claim
1. An assembly comprising:
- a vial having (i) an upper enclosure configured to store a sample and (ii) recess-defining material defining a lower recess located below a bottom surface of the upper enclosure; and
a retainer configured to be inserted within the lower recess and engage an inner surface of the lower recess defined by the recess-defining material to retain a unique RFID tag located within the lower recess to form an RFID tag/vial assembly, wherein;
the unique RFID tag unambiguously distinguishes the RFID tag/vial assembly from every other RFID tag/vial assembly having its own unique RFID tag; and
the retainer has one or more rigid tabs configured to gouge into the inner surface of the lower recess defined by the recess-defining material resulting in permanent deformation of the recess-defining material when attempting to remove the retainer from within the lower recess in order to prevent removal of the retainer from within the lower recess to retain the RFID tag within the lower recess between the retainer and the bottom surface of the vial'"'"'s upper enclosure.

Abstract
RFID tags are affixed to vials used to store samples, such as biological samples stored in liquid nitrogen dewars or mechanical freezers. In one set of embodiments, an RFID tag is inserted into a recess at the bottom of a vial and held in place by an insert that engages with vial structure. In another set of embodiments, the RFID tag is retained in the recess by directly engaging with the vial structure and without using a separate insert. Mechanisms for keeping the insert and/or tag in place include tabs that gouge into the vial material, clips that allow the insert/tag to be inserted, but not removed, and holes in the side wall of the vial recess that receive tabs extending from the insert/tag. Tag-insertion techniques enable tags to be affixed to vials either before or after insertion of the sample, thereby enabling retrofitting of existing sample-storing vials with tags.

8. An RFID tag/vial assembly comprising:
-
a vial having (i) an upper enclosure configured to store a sample and (ii) recess-defining material defining a lower recess located below a bottom surface of the upper enclosure; an RFID tag located within the lower recess; and a circular, metal spring surrounding the RFID tag, the circular, metal spring having one or more metal tabs that gouge into an inner surface of the lower recess defined by the recess-defining material resulting in permanent deformation of the recess-defining material when attempting to remove the RFID tag and the circular, metal spring from within the lower recess in order to retain the RFID tag within the lower recess. - View Dependent Claims (9)
