Receptacle rack having an electronic memory element
View Patent ↗A system and method for tracking items, such as receptacles, during a process employs a rack configured to hold one or more receptacles. Each receptacle includes a machine-readable label providing information regarding the receptacle, such as contents thereof and process(es) to be performed thereon, and each receptacle-receiving position of the rack has associated therewith a machine-readable label identifying the receptacle receiving location. The rack also includes a memory element to which electronic data may be written. A label reading device reads the machine-readable label on each receptacle and the position-indicating, machine-readable labels on the rack. Information obtained from the machine-readable labels is written to the memory element, so that for subsequent processing of the receptacles carried on the rack, information relating to each of the receptacles can be obtained by reading the information written to the memory element. A tamper prevention element provides an indication of whether the rack may have been tampered with after data is written to the memory element.
1. A receptacle rack comprising:
a sample receptacle holding structure defining a plurality of sample receptacle-receiving pockets, each configured to receive and hold a sample receptacle;
machine-readable position data associated with each sample receptacle-receiving pocket and comprising information relating to a position of each sample receptacle-receiving pocket; and
an electronic memory element configured to store information relating to sample receptacles held within receptacle-receiving pockets of the sample receptacle rack and the information relating to a position of each sample receptacle-receiving pocket.
2. The receptacle rack of claim 1 , further comprising at least one sample receptacle held within a sample receptacle-receiving pocket, the receptacle including machine-readable sample receptacle data comprising information relating to the contents of the sample receptacle.
3. The receptacle rack of claim 2 , wherein the machine-readable receptacle data comprises a bar code disposed on the sample receptacle.
4. The receptacle rack of claim 1 , wherein the machine-readable position data comprises a bar code disposed adjacent to each sample receptacle-receiving pocket.
5. The receptacle rack of claim 1 , wherein the memory element comprises a radio frequency identification (RFID) tag.
6. The receptacle rack of claim 1 , wherein the memory element comprises a touch memory element.
7. The receptacle rack of claim 1 , further comprising a cover configured to be removably secured to the receptacle-holding structure so as to cover any receptacle(s) held within receptacle-receiving pockets defined by the receptacle-holding structure.
8. The receptacle rack of claim 2 , wherein the machine-readable sample receptacle data comprises information identifying a sample material contained in the sample receptacle.
9. The receptacle rack of claim 2 , wherein the machine-readable receptacle data comprises information identifying a reagent contained in the sample receptacle.
10. A receptacle rack comprising:
a sample receptacle holding structure defining a plurality of sample receptacle-receiving pockets, each configured to receive and hold a sample receptacle;
an electronic memory element configured to store information relating to sample receptacles held within receptacle-receiving pockets of the sample receptacle rack and the information relating to a position of each sample receptacle-receiving pocket; and
a tamper prevention element configured to indicate if the cover, once it is secured to the receptacle-holding structure, has been removed from the receptacle-holding structure after the information is stored on the electronic memory element.
11. The receptacle rack of claim 10 , wherein the tamper-prevention element comprises an indicator element that is alterable between a first configuration when the cover is secured to the receptacle-holding structure while information is being stored, or has been stored, on the electronic memory element, and a second configuration when the cover is removed from the receptacle-holding structure after the information is stored on the electronic memory element.
12. The receptacle rack of claim 10 , wherein the indicator element comprises a movable flag mounted on the cover or the receptacle holding structure to be movable between a locked position and an unlocked position.
13. The receptacle rack of claim 12 , further comprising:
a flag biasing element configured to bias the flag into its unlocked position; and
flag holding structure configured to hold the flag in its locked position while the cover is secured to the receptacle-holding structure, wherein the flag holding structure is configured such that it will no longer hold the flag in its locked position if the cover is removed from the receptacle-holding structure so that the flag biasing element will cause the flag to return to its unlocked position.
