Abstract:
A system for automation of laboratory analyzers that utilizes radio frequency identification (RFID) tags and radio frequency identification (RFID) readers to identify containers and vessels, and the contents thereof, that are employed in the system. Radio frequency identification tags, conforming to the guidelines of ISO 14443 or ISO 15693 or ISO 18000, are positioned on the items of interest, such as, for example, reagent containers, sample containers, and microplates. These tags can be read by and written to by either a moving antenna of a RFID reader or a stationary antenna of a RFID reader. Reading of RFID tags and writing to RFID tags are controlled by software.
Abstract:
A system for managing the inventory of reagents for a laboratory automation system is disclosed. The system for managing the inventory of reagents comprises a controller, software for the controller, and a refrigerator capable of refrigerating reagents, detecting the presence or absence of reagents in the refrigerator, and detecting the location of reagents in the refrigerator. The system for managing the inventory of reagents is connected to a laboratory automation system. The laboratory automation system comprises at least one clinical analyzer. A typical system for managing inventories of reagents includes an operator interface for the loading of boxes of reagents and other supplies, radio frequency identification system for identification of inventory and tracking, robotic mechanisms for loading containers onto the track system and removing containers from the track system, de-capping equipment, refrigeration equipment, and information technology connections to laboratory analyzers and vendors.
Abstract:
A system and method for the tracking of medical instrument, components, assemblies, and sub-assemblies thereof, and maintenance information relating to the foregoing. According to the system, radio frequency identification tags are attached to or affixed on the medical instrument itself for the purpose of locating, identifying, monitoring, tracking the medical instrument and updating the maintenance and replacement activities relating to the medical instrument. In addition, radio frequency identification tags are attached to or affixed on the components, the assemblies, and the sub-assemblies, of the medical instrument in order to locate, identify, monitor, track the components, the assemblies, and the sub-assemblies and update the maintenance and replacement activities relating to these components, assemblies, and sub-assemblies. The medical instrument itself can have a radio frequency identification tag; each major component of the automated diagnostic instrument can have a radio frequency identification tag; each minor component of the automated diagnostic instrument can have a radio frequency identification tag on the container in which it is packaged. A master radio frequency identification tag (108) correlated with a database is needed in order to collect information relating to all of the radio frequency identification tags associated with the medical instrument.
Abstract:
A centrifuge to which sample tubes can be introduced while the centrifuge is in motion. The centrifuge comprises a carousel having an upper portion and a lower portion. The upper portion of the carousel has a plurality of positions for sample tubes for a centrifugation operation, a plurality of drive mechanisms attached to the upper portion of the carousel, a movable element mounted upon each drive mechanism, the movable element capable of traversing the length of the drive mechanism when the drive mechanism is actuated, a sample tube-holding assembly comprising a sample tube holder and a bearing attached to each movable element, and at least one balancing element capable of contributing to a force vector that cancels an imbalance vector generated by rotation of the centrifuge.
Abstract:
A system for managing bulk liquids for an automated clinical analyzer. The system comprises (a) at least one local reservoir for storing a bulk liquid for impending use, (b) at least one container for holding a bulk liquid before the liquid is transferred to a local reservoir, and (c) a controller for monitoring the level of a bulk liquid in a local reservoir. The local reservoir for storing a bulk liquid for impending use can be a trough. The use of troughs for storing a reagent, a diluent, or some other treating agent for impending use enables an aspirating/dispensing device having a plurality of pipettes to aspirate and dispense the reagent, diluent, or other treating agent at a high rate of throughput. The controller can monitor the level of a liquid in (a) a local reservoir for storing a bulk liquid for imminent use and the level of liquid in a (b) container for holding a bulk liquid before the liquid is transferred to a local reservoir. In the laboratory automation system described herein, the container for holding a bulk liquid before the liquid is transferred to a local reservoir can be a bottle. Other desirable features in the system include, but are not limited to, pump(s), valves, liquid level sensors.
Abstract:
A device and method for extending the useful life of a bulk liquid used in an automated clinical analyzer. Air from the atmosphere surrounding the automated clinical analyzer that displaces the bulk liquid consumed from a container is routed through a gas scrubber in order to remove or at least reduce the quantity of at least one contaminant present in that air. The gas scrubber is positioned between the bulk liquid in the container and the atmosphere surrounding the container. The gas scrubber contains a reagent that is capable of reacting with a contaminant in the atmosphere, whereby a required characteristics(s) of the bulk liquid does (do) not change excessively prior to the date that the bulk liquid is consumed. For example if the contaminant is carbon dioxide, and the required characteristic of the bulk liquid is the level of pH of the bulk liquid, the reagent in the gas scrubber prevents the level of pH of the bulk liquid from changing excessively prior to the date that the bulk liquid is consumed.
Abstract:
In one aspect, a computer readable memory medium comprising program instructions for graphically developing a connectivity driver is provided. The computer readable memory medium is a non-transitory medium. The program instructions are executable by a processor to generate a purchase order for a laboratory item, transmit the purchase order to a remote computer in order to communicate the purchase order to a vendor, receive an advance shipping notice generated in response to the purchase order, receive item information stored in an RFID tag of a tagged item received at the delivery location, and check the item information against the advance shipping notice in order to verify that the tagged item is the same as the ordered laboratory item. The purchase order specifies a delivery location.
