DETAILED DESCRIPTION OF THE INVENTION

[0032] The invention focuses on a modular design concept for a Track device, able to supply multiple work-cell bound analyzers as well as multiple cores of a single analyzer with patient samples, reagents, consumables and/or other kinds of supplies materials. The concept shall be operable with various future OEM analyzer developments.

[0033] Loading and unloading of a Track device based solution is realized via centralized Loading/Unloading Modules that provide interfaces to the users and towards the Track devices. If necessary, these Loading/Unloading Modules can also comprise identification means like a code reader to e.g. check for a patient sample ID, a reagent type or expiration date, a consumable type or ID or others. With their interface to the user they allow for manual loading and unloading of all relevant supplies, their interfaces towards the tracks allow for distributing or receiving carriers to and from the track lanes.

[0034] A solution is described providing patient samples exemplary via four position sample racks to a cluster of analyzers or cores. This is exemplarily for the overall concept. The concept is not limited to using four position sample racks.

[0035] The way multiple analyzers or cores can be oriented in a system setup may also vary. FIG. 1 shows a back to back arrangement with the track devices being located in the middle between analyzers/cores. A centralized unit for loading, unloading and if necessary identification of the supplies is attached to one end, however position for loading/unloading can be chosen freely and there might be more than one unit for it.

[0036] In this scenario there are four track lanes running along each Track device. The ones in the middle are fast forward and fast reverse lanes to pass-by analyzers or cores. The outer ones are directly accessible by analyzers/cores to access samples, reagents or supplies. The number of these lanes can of course vary, depending on specific needs and throughput. Where and how analyzers or cores interact with track lanes is highly depending on the design and installation and is not described in detail. It can e.g. be a pick and place handling accessing consumables or a pipettor reaching out of a analyzer core to aspirate a sample or a reagent out of a tube or bottle. A track device installation can also provide multiple different supplies.

[0037] At the end of each Track device there is one lane change drive able to allow a carrier to switch lanes (comp. FIG. 1). Position and number of these drives may vary, depending on a specific solution. The concept of a lane change drive is describe in more detail later.

[0038] As an alternative, the FIG. 2 shows a linear positioning of analyzers/cores. Track devices are located at one side of analyzers/cores. A centralized unit for loading, unloading and if necessary identification of the supplies is attached to one end.

[0039] In FIG. 2, there are three track lanes running along each module. The upper ones would be fast forward and fast reverse lines to pass-by analyzers or cores. The lower one would directly be accessible by analyzers/cores to load/unload samples, reagent or supplies. Where and how analyzers or cores interact with track lanes is again highly depending on the design and installation and is not described in detail.

[0040] A lane change drive is one possible solution to allow a carrier to change the lanes on a track device. In schematics of FIG. 3 it is described exemplarily with a 4-position carrier. Once a rack or carrier has to move over to a neighboring track without changing the lane, the lane change drive would be moved to the relevant lane and the rack will be transported through the lane change drive section.

[0041] In case a lane change is needed the rack would be transported into the lane change drive section, stay there while the drive moves to a different lane and from there be transported further. As alternatives or add-ons track switches can be inserted to a Track device for redirecting a carrier or rack.

[0042] Several Track devices connected to each other allow for a big variety of routing options and for a wide variety of error recovery modes in case of e.g. one lane drive errors out. The lanes in such an installation would allow for being used as a temporary storage or buffer for racks or carriers to equalize throughput or processing variances.

[0043] Sensors at each end of one specific drive section allow for presence sensing and counting of carriers in the relevant sections (FIG. 4). When e.g. a rack is moved into the lane change drive, its front surface would trigger the entry sensor. Once fully moved into the drive section, the entry sensor signal would drop and a little later the exit sensor would be triggered. Between the last two sensor signal switches the carrier would be perfectly positioned in the lane change drive section.

[0044] Sensor type, numbers and logic might vary depending on the preferred and approached solution.

[0045] The advantages related to the subject matter of the invention can be summarized as follows: [0046] The invention offers a generic approach to supply work-cell bound analyzers as well as a multi-core single analyzer with patient samples, reagents, consumables and/or other kinds of supplies materials. [0047] It offers easy adaptability to a variety of similar analyzers of functional cores of analyzer with toolbox-like elements. [0048] It allows for easy service, low spare parts cost and low effort for field service and training due to similar or identical components in various installations. [0049] It allows for good reliability of components and installations due to reuse and a high level of experience and understanding of these components over time. [0050] Software engineering to control different installations can benefit from reusing available libraries. [0051] Hardware and software effort and cost can be lowered once the toolbox components and libraries are developed. [0052] The invention offers time to market can be reduced for a new design.

[0053] It is obvious for a skilled person that the follwing embodiements are within the scope of the present disclosure [0054] An alternative design could incorporate a different number of lane drives or lane change drives per Track device. [0055] An alternative design could be realized with different dimensions of lane drives or lane change drives per Track device. [0056] Loading, unloading, buffering, storage and indentification of carriers or supplies can be established differently. [0057] The design can support different from the shown carriers for different from the shown numbers of samples, reagents or other supplies [0058] The design could incorporate all types of drive and sensing technologies for carriers, bottles, tubes, consumables, etc. [0059] The design can be installed into analyzers, in combination with analyzers to the analyzers directly, to the lab (e.g. floor) or to a common platform with the analyzers.
