Embodiment Construction

[0093] Figure 10 An example of a system 900 for processing sample tubes is shown schematically. System 900 includes a plurality of work units 901-909. In particular, system 900 includes a pre-analytical workcell 901, a post-analytical workcell 909, multiple analytical workcells 902-906 adapted to preferably process sample tubes on a single Two analytical workcells 907, 908 for processing sample tubes in a consistent manner. The system 900 further includes a transport unit 920 adapted to transport sample tubes on a single carrier and rack, from one work cell to any other work cell as needed. System 900 further includes decapping / recapping systems 911-918, corresponding to work units 901-908, respectively, for when samples need to be removed and / or liquids need to be dispensed and / or sample parameters need to be determined from The sample tube is decapped and used to reclose the sample tube before it is transferred to another work cell 901-909. The sample tubes are thus tra...

Abstract

The present invention refers to a system (900) for processing sample tubes (12) comprising biological samples, the system (900) comprising two or more work cells (901-909) for processing samples, wherein in correspondence to at least two of the work cells (901-909), the system comprises one of the following units: a pipetting unit (921-928) for withdrawing a volume of sample from a sample tube to be processed by the work cell and / or dispensing a volume of liquid into the sample tube, an analytical unit (931, 937) for determining at least one sample parameter of a sample contained in a sample tube. The system (900) further comprises a decapping / recapping device (911-918) for each of the at least two work cells (901-908) for removing a closure (11) from a sample tube (12) and for reclosing the sample tube (12) before it is transported to another work cell (901-909).

Description

technical field [0001] The invention relates to the field of in vitro diagnostics and to a system for processing sample tubes comprising a plurality of working cells for processing samples. The invention also relates to a method of processing a sample tube comprising withdrawing a volume of sample from a tube processed by a work unit and / or dispensing a volume of liquid into the sample tube. Background technique [0002] From various healthcare facilities, biological samples, such as blood samples, commonly appear in laboratories in different kinds of tubes with various caps. So called because they are used to collect samples, eg by venipuncture, these are typically primary sample tubes. [0003] Some instruments can handle primary sample tubes without removing the cap, ie, access the sample contained in the primary tube by piercing the cap with, for example, a pipette needle. However, not all caps are suitable for this procedure, and not all types of instruments and / or as...
