System and methods for lab automation data sharing
View Patent ↗A method for sharing system information data in a network of two or more diagnostic instruments for performing assays is provided. The system information data includes operating information for the diagnostic instruments in the network. The method includes: sending a system information metadata packet to at least a first diagnostic instrument in the network, wherein the system information metadata packet, is associated with system information data on a second diagnostic instrument in the network and comprises one or more attributes of a system information data packet containing the associated system information data; receiving a request from the first diagnostic instrument to send the system information data packet, and in response to the request from the first diagnostic instrument to send the system information data packet, sending the system information data packet containing the associated system information data to the first diagnostic instrument.
1 . A method for sharing system information data in a network of two or more diagnostic instruments for performing assays, wherein the system information data comprises operating information for the diagnostic instruments in the network, the method comprising:
receiving a system information metadata packet by a first diagnostic instrument in the network, wherein the system information metadata packet is associated with system information data on a second diagnostic instrument in the network and comprises one or more attributes of a system information data packet containing the associated system information data;
determining from the system information metadata packet that the first diagnostic instrument needs the associated system information data contained in the system information data packet by comparing the one or more attributes of the system information metadata packet with local data;
in response to determining from the system information metadata packet that the first diagnostic instrument needs the associated system information data contained in the system information data packet, sending a request to the second diagnostic instrument to send the system information data packet;
receiving the system information data packet containing the associated system information data from the second diagnostic instrument;
in response to receiving the system information data packet containing the associated system information data from the second diagnostic instrument, updating the local data based on the associated system information data from the second diagnostic instrument; and
operating the first diagnostic instrument to perform an assay using the updated local data.
2 . The method of claim 1 , wherein the system information data further comprises information about at least one of the following: users, master lots for assay reagents, controls, calibrators, assay reagent kits, assay cartridges, and external quality control (EQC) definitions.
3 . The method of claim 1 , wherein comparing the one or more attributes of the system information metadata packet with local data comprises comparing a first time with a second time, wherein the first time represents when the system information data was last changed and the second time represents when the local data was last changed.
4 . The method of claim 3 , wherein comparing a first time with a second time comprises normalizing the first time by adding an offset corresponding to the second diagnostic instrument, wherein the offset is calculated based on a difference in clock time for the second diagnostic instrument and an estimated travel time from the second diagnostic instrument to the first diagnostic instrument.
5 . The method of claim 4 , wherein multiple values for the difference in clock time and the estimated travel time are determined from repeating the calculation and the offset is calculated based on an average of the multiple values for the difference in clock time and the estimated travel time.
6 . A network of analyzers for performing assays, each analyzer in the network of analyzers comprising a processor and instructions stored on a non-transient computer readable medium which, when executed, cause the processor to:
receive a system information metadata packet by a first analyzer in the network of analyzers, wherein the system information metadata packet is associated with system information data on a second analyzer in the network of analyzers and comprises one or more attributes of a system information data packet containing the associated system information data;
determine from the system information metadata packet that the first analyzer needs the associated system information data contained in the system information data packet by comparing the one or more attributes of the system information metadata packet with local data;
in response to determining from the system information metadata packet that the first analyzer needs the associated system information data contained in the system information data packet, send a request to the second analyzer to send the system information data packet;
receive the system information data packet containing the associated system information data from the second analyzer;
in response to receiving the system information data packet containing the associated system information data from the second analyzer, update the local data based on the associated system information data from the second analyzer; and
operate the first analyzer to perform an assay using the updated local data.
7 . The network of claim 6 , wherein the system information data comprises information about at least one of the following: users, master lots for assay reagents, controls, calibrators, assay reagent kits, assay cartridges, and external quality control (EQC) definitions.
