Description
STORAGE AND FEEDING OF DISPOSABLE PIPETTE TIPS
DESCRIPTION
Field of the invention
[0001] The present invention relates to a storage and feeding system for pipette tips for automated analyser systems.
Brief description of the related art
[0002] Automated analyzer systems for use in clinical diagnostics and life sciences are produced by a number of companies. For example, the STRATEC' Biomedical AG, Birkenfeld, Germany, produces a number of devices for specimen handling and detection for use in automated analyzer systems and other laboratory instrumentation.
[0003] Pipetting devices in automatic analyzers are routinely used in clinical diagnostics and life sciences for tasks such as specimen handling, specimen preparation, detection and analysis. Thereby, pipetting devices use pipetting tips to transport liquids like patient samples and assay components and bring them together in a reaction vessel for instance. Thus, pipette tips have constantly to be provided for specimen handling.
[0004] Known disposable tip storage solutions in diagnostic analyzers are usually based on disposable tip tray loading. Those trays have typically a capacity of 96 tips. The pipette tips are loaded into a loading area directly onto a deck of an analyzer. Usually, such a loading area is a drawer-based module. However, space and time necessary for feeding tips will increase with the number of tips to be loaded. Anapyser for high through-put analyis will thus require a lot of space for stroring and feading pipette tips. Bulk loading of tips, with loading funnels and tip sorters are also very common.
[0005] Published International Patent Application No. WO 2010/118374 Al describes methods and devices for storing, handling, loading or dispensing of pipette tips. Some embodiments of this document allow repetitive loading of an array of multiple pipette tips that are stored in a nested configuration. Pipette tips may generally be engaged with a distal nozzle of a pipettor or similar device in order to draw and drop liquid slugs in precise amounts. Such tips may be used for the transfer and handling of liquids for applications such as titration and dispensing of liquids, DNA sequencing, cycle sequencing, PCR and other DNA analysis as well as other liquid handling applications. For many of these applications, large numbers of samples must be processed in a precise manner and, as such, a large number of pipette tips are used for such methods. In order to avoid cross contamination of samples, pipette tips are typically used only once for each sample being processed. Because of the large number of samples being processed and the single use nature of the pipette tips, a large number of pipette tips need to engaged with pipettor type devices and then removed from those devices and disposed of [0006] Published International Patent Application No. WO 2008/021722 Al discloses a method of loading a plurality of pipette tips on a plurality of mandrels of a pipettor is provided. A plurality of pipette tips are inserted in a plurality of receptacles of a tip loading assembly. The plurality of pipette tips are oriented with respect to each other by a plate. The tip loading assembly includes, but is not limited to, an insertion surface. The insertion surface includes the plurality of receptacles configured to accept the plurality of pipette tips. A receptacle from among the plurality of receptacles includes a receptacle wall and a beveled surface that extends from at least a portion of the insertion surface. A retention force is applied to the plate. The plurality of pipette tips are attached to a plurality of mandrels of a pipettor and are separated from the plate, [0007] In published International Patent Application No. WO 2005/119269 Al a system for selectively loading pipettes onto a multichannel pipettor using a pipette holder which projects the engagement ends of selected pipettes further away from a support surface compared with a remainder of pipettes retained in the holder is disclosed.
[0008] Pipette feeding known in the prior art rektes to tray based tip loading methods. These commonly known solutions require a large place on a deck independend from whether they are used for load manual or automated loading. Additionally, in analyzers with continuous loading concepts, where user and system are able to access the same area at the same time, additional measures to ensure user safety have to be implemented.
Object of the invention [0009] The object of the invention is to reduce the overall footprint of a diagnostic analyzer by reducing the required space for storing and feeding disposable tips on a main deck of an automated analyzer.

Detailed description of the invention
[0027] The present invention reduces efficiently the required space for disposable tips on a deck of an automated analyzer dramatically. The disposable tips will be loaded below a main deck, e.g. into a cabinet of a floor standing analyzer. This will reduce the size of such an analyzer system as it leads to reduced space requirements on said main deck. This results also in a reduced overall footprint of the analyzer. Additionally, the invention will improve the usability and the continuous loading capability in the analyser system. Instead of a large storage area, just a small slot is required to feed separated disposable tips for the pipettor to pick up.
[0028] The feeding system of the disposable tips is based on belted tips, which will be loaded and stored below the deck in e.g. cabinet of a system. Therefore, the required space on the deck is reduced.
[0029] The belted tips will be provided on the analyzer's deck by a motor driven "belt feeding" device. Additionally, the tips will be separated automatically be a tip separation device. The separated single tips are then available for the pipettor of an automated analyser in the pipetting area. The pipettor is now able to pick the tips to dispense or aspirate different kinds of liquids like patient samples or reagents.
[0030] Belting of the single disposable tips can be made / manufactured with: - in-mold injection process with the same or a different injection raw material, - a self-adhesive tape, - a premanufactured belt, where the tips are just clicked in.
[0031] The disposable tip belt can be packaged as a coil or meander in a special box and loaded automatically or manually to the analyzer. The disposable tip belt can be packaged as a spiral in a special box with or without automation interfaces.
[0032] FIG. I shows tips that are connected by a connecting member or element which may be designated as belt or bars in parallel to the longitudinal tip axis or volume of te tip. Pipette tips which are connected as shown in FIG. 1 can be rolled as shown in FIG. 3 or FIG. 4 like a belt. The tip's openings are arranged in a plane on one side.
[0033] FIG. 2 shows exemplary tips which are connected by a connecting member or an element that is arranged perpendicular to the longitudinal axis of the tip or its volume. Such an element can be rolled as shown in FIG. 5 with the openings of the tips being aranged on the outer circumference of a spiral cylinder. The arrangement of the tips depends on the needs of the respective automated analyser system for reaching the openings of the tips.
[0034] Independent from the manner in which the tips are connected, the present invention is independent from any further delivery bodies like trays for taking up pipette tips. The advantages of the present invention can be summarized as - Reduced overall size of the analyser due to reduced space requirements of a system's deck or device - User friendly interface - Scalable solution - High grade of automation - Improved continous loading capacity - Reduction of solid plastivc waste due to absence of additional tip trays - Cheaper solution [0035] The foregoing description of the preferred embodiment of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed, and modifications and variations are possible in light of the above teachings or may be acquired from practice of the invention. The embodiment was chosen and described in order to explain the principles of the invention and its practical application to enable one skilled in the art to utilize the invention in various embodiments as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims appended hereto, and their equivalents. The entirety of each of the aforementioned documents is incorporated by reference herein.
