I. FIELD OF THE INVENTIONThe present invention in at least one embodiment relates to a system and method for providing an indication of whether a specimen sample has been tampered with or otherwise accessed. The present invention in at least one embodiment relates to a system and method for identifying and tracking specimen samples currently in storage conditions within containers, as well as, prospectively collected specimen samples. More particularly, the present invention in at least one embodiment relates to a tamper evident RFID inventory and accountability system and method for efficiently identifying and tracking biological and chemical specimens while being stored.
II. BACKGROUND OF THE INVENTIONBiological and chemical sample containers are commonly used in the medical, chemical, bioscience and drug research and testing industries. These containers are typically made of plastic, glass, or a similar non-reactive material and cover a range of sizes and types. However, smaller vials such as, 0.5 mL, 1 mL, 1.5 mL, 1.8 mL, and the like, are widely used in the medical, chemical, bioscience and drug research and testing industries. In these industries, unique specimen samples (for example, blood or urine in the drug testing industry) are maintained in individual vials. The individual vials are often stored within a container such as a box that typically holds up to 100 vials per box. Laboratories and research facilities are two examples where the mission requires storage of specimen samples that number into the tens of thousands or hundreds of thousands in incubators, refrigerators, freezers, cryogens, and similar storage devices with increasing numbers of samples projected for collection, use and storage. In aggregate, these samples number into the millions. Therefore, given the number of samples that are stored it is imperative that each specimen sample is reliably identified and tracked in order to maintain the integrity of the research and testing, and to meet applicable reporting requirements.
Some prior specimen identification and tracking systems have including printed (written or handwritten) labels that require visual inspection, or a unique bar code along the side of the container that is typically located and scanned using a hand held optical scanner. The printed label systems require users to remove the trays from storage and remove the specimen vials from the tray in order to identify and track the specimen. The bar code labeling systems utilize a light beam emitted from the scanner to “read” the bar code label. Because the relationship of the single-use test device or biological or chemical sample container is by nature transitory and such items are either discarded following use or cleansed by some process, prior systems did not provide a mechanism for positive tracking of the sample or test object other than by barcode or handwritten labels. Handwritten, adhesive label and bar code technology requires positive line-of-sight and may be adversely affected by the contents of the sample, reagents and/or by physical handling of the test device or specimen container which may degrade the label such that it cannot be read by human eye or an optical reader. Bar code technology also requires sample containers to be removed from storage and handled individually, resulting in lengthy inventory processes that create a significant potential for loss or damage to the container and/or specimens because of their removal from the storage device.
Securely and efficiently protecting samples against tampering and contamination remains a critical concern. The vast majority of the existing samples are stored insecurely in a manner prone to tampering and contamination—often in vials having only a flip top, screw top, etc. that can be easily breached by unauthorized personnel. For example, a critical and urgent need exists to maintain a one-hundred percent inventory and accountability of all Biological and Select Agent and Toxin (BSAT) samples in the Department of Defense (DoD) Inventory. In addition, mechanisms must be put in place to monitor and notify of tampering or unauthorized access to such samples. BSAT samples must be secured in a manner appropriate to guard against misuse, theft, loss or accidental release. These inventory and security measures must be implemented in a coordinated manner that balances security and efficiency with access to scientists for the legitimate use of BSAT. The same need applies to numerous biological science laboratories in hospitals, blood storage facilities, fertility clinics, etc., i.e., anywhere inventory and accountability of valued or sensitive items are required at a moment's notice.
Increasing regulatory requirements by human and animal ethical use policies, as well as, state agency imposed requirements mandate accurate and efficient accountability of all specimens, prospective and retrospective. The increased requirements in addition to the mounting volumes of samples requiring storage demands a significant amount of additional administrative work to efficiently, securely and accurately inventory and account for biological samples. Currently, most laboratory personnel simply write a coded sequence number on the sample container directly or use an adhesive label to identify the contents. Limited by line-of-sight, the primary strategy to account for a sample is to physically remove it from its current storage condition such as in an incubator at approximately 37 C or a freezer, count the vials one-by-one, affirming that the label indicates a material exists in the container. Multiple permutations on line-of-sight strategies to streamline the inventory process are used. However, additional limitations create significant inefficiencies. But these inefficiencies can be overcome by use of the present invention.

V. DETAILED DESCRIPTION OF THE DRAWINGSWhile the present invention is susceptible of embodiments in various forms, there is shown in the drawings and will hereinafter be described some exemplary and non-limiting embodiments, with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated.
The present invention provides different embodiments for devices, methods and systems for creating, maintaining, identifying, tracking, and controlling inventories of biological and chemical samples containers and their contents at the point of containment. In at least some embodiments, the present invention provides a tamper evident system and method that is capable of use in a retrofit implementation, while in further embodiments portions of the system are incorporated into the construction of the sample container. In at least some embodiments, the present invention provides a tamper evident RFID inventory tracking and accountability system and method. In at least some embodiments, the present invention provides a sample lock that includes an embedded storage medium, such as an RFID chip, integrated circuit (IC), or comparable technology, that allows the sample to be quickly and easily identified, tracked and accounted for without the need to remove, visually inspect, and/or handle the sample. In at least some embodiments, the present invention provides a sample container tray or box having one or more integrated RFID transceivers that interrogate and report the RFIDs associated with the individual samples.
In at least one embodiment, the present invention provides a tamper evident sample locking device, as illustrated in
The embedded data storage mechanism 135 can be programmed to store and transmit a variety of information related to the sample to an associated data reader (not shown), e.g., an RFID reader or transceiver. The embedded data storage mechanism 135 may also be designed to provide an electronic indication of tampering upon the opening of the locking device 100. The locking strip 110 includes locking mechanisms 140, e.g., raised notches having projections, which securely engage with apertures 150 to lock the sample locking device 100 around the cap 175 of a specimen sample container 170. Based on this disclosure, it should be appreciated that locking mechanisms can take a variety of structures. The locking strip 110 may also include optional depression or fault lines 160 that improve the deployment of the sample locking device 100 by making it easier to bend and lock the locking strip 110 around the sample container. Damage or removal of the sample locking device 100 will result in a traceable and/or noticeable alteration of the device 100. Once locked, the sample locking device 100 ensures that the sample container remains closed and cannot be opened without presenting a clear physical and/or electronic indication of tampering.
As illustrated in
The sample locking device 400 and locking collar 440 are preferably formed of a resilient but pliable material, e.g., polypropylene, resin, or a similar pliable rigid polymer. The material should be resilient enough in the data storage alternative embodiments to protect the optional embedded data storage mechanism, but pliable enough to allow the locking members to bend such that they can be drawn to fit snugly around the sample container 470 having a cap 275, as illustrated in
As illustrated in
In further alternative embodiments, the locking collar as discussed above with respect to
While the preferred embodiments of the above-described invention include an embedded data storage mechanism, the invention is capable of being deployed without the use of such a mechanism. In embodiments that do not include a data storage mechanism, the sample locking device when placed over the cap would still prevent access to the sample container and provide a clear physical indication of tampering. Those embodiments would therefore still function as an effective tamper evident sample locking device. However, those embodiments would not provide an electronic indication of tampering.
The cryogenic box 500 in at least one embodiment is formed of a suitable resilient and temperature resistant material that is appropriate for the intended use of the cryogenic box 500. The materials should be appropriate to withstand very low temperatures (for example, temperatures associated with use in liquid nitrogen) and/or very high temperatures (for example, temperatures associated with use in incubators) and the like without presenting a risk of deterioration to the samples contained within the cryogenic box 500 or the cryogenic box 500 itself. The cryogenic box 500 is therefore suitable for use within a variety of storage and testing environments including storage freezers, refrigerators, incubators, etc.
In some embodiments, the smart sample box or cryogenic box may not include a smart lid. While the embedded transceiver 525 is illustrated as being contained with the smart lid 520, other arrangements of the embedded transceiver 525 may also be utilized without departing from the invention, including placing the embedded transceiver within the bottom tray 510, beneath the bottom tray 510, above the top 520, or within very close proximity to the samples such that the communication can be established. In other embodiments, the embedded transceiver 525 may be attached to or embedded in a mat suitable for use within the storage environment such as within a refrigerator or cryogenic freezer. The mat can then be placed within the storage device, e.g., on the shelf of a refrigerator, such that the embedded transceiver 525 can sense signals from within storage trays placed on the shelf.
The method of present invention provides a reliable and accurate specimen sample maintenance, tracking and identifying method that ensures the integrity of the specimen samples during storage, testing and/or transport. The method utilizes an embedded data storage mechanism that is capable of receiving and storing data, as well as transmitting data when queried. The RFID provides a means of continual and instant querying and verification of the specimen sample. In addition to specimen vials other suitable container may also be used including, for example, Petri dishes, flasks, bottles, test-tubes, re-sealable plastic bags, pharmaceutical type storage containers, bins, clam-shell cases, bottle stoppers or corks and plastic cassettes.
An alternative embodiment includes using the above-described embodiments to secure sample containers. An existing sample container is removed from storage, for example, as part of an inventory. Over the container is slid the collar of one of the above-described locking devices. The collar engages and/or tightens around the container to resist removal. The locking components are attached or folded over the cap of the sample container securing the cap to the sample container such that if the sample container is accessed, the locking device will need to be physically manipulated and/or damaged resulting in a physical indication that access of the sample container has occurred. One particularly useful application of this method is in situations where a chain of custody is desired.
In a further alternative embodiment, the embodiment depicted in
The present invention in at least one embodiment can be added, i.e., retrofitted, to existing sample containers to provide an efficient and effective means for the identification, inventory, tracking and reporting of the samples. The ability to retrofit previously existing inventories with tamper-evident RFID locking devices provides significant savings of time and resources related to the maintenance, inventory and reporting processes.
The present invention in a further embodiment utilizes an RFID transceiver and system which can actively or passively query on-demand or as programmed to report all or part of the data associated with the RFID embedded containers. The RFID chip is imprinted with identification that can allow or disallow access to the stored data contingent on the user-query and validation response. The system in at least one embodiment reads from outside a storage container the presence of the RFID embedded sample containers. The system in a further embodiment is programmed to report an alert signal upon the detection of tampering of a sample container.
The embedded data storage device of the present invention may also be used to provide electronic data generated entries that auto-fill an associated electronic laboratory notebook, inventory record, inspection report or similar documentation. The embedded data storage device of the present invention may also communicate with and report the detection of other devices including, for example, stir bars, incubators, etc., to report start/stop time of incubation, stirring, experiment condition or designated experimental endpoint.
