AI Technical Summary

Problems solved by technology

Narrower manufacturing tolerances with respect to the coupling mechanism consisting of coupling pins and coupling holes will lead to increased wear and tear, thus requiring more frequent replacement of the parts involved, which in turn will lead to increased maintenance costs for automatic analyzers
[0015] Due to the temporary elimination of the contact between the coupling pin and the coupling hole, it can occur that the liquid sample is not mixed as desired and, therefore, erroneous measurement results are produced

Embodiment Construction

[0057] figure 1 is a schematic diagram of the automated analyzer 1 with some of the components contained therein. Here, only the most important components are shown in a greatly simplified manner in order to explain the basic functions of the automatic analyzer 1 without a detailed description of the individual parts of each component.

[0058] The automatic analyzer 1 is embodied to carry out different types of analyzes on blood or other body fluids in a fully automatic manner, which does not require action by the user. Instead, the necessary intervention by the user is limited to maintenance or repair and refilling work, eg if the cuvette needs to be refilled or the liquid container needs to be replaced.

[0059] The patient sample is fed to the automatic analyzer 1 via a feed track 2 on a carriage not described in detail. Information about the analysis to be carried out for each sample can be transmitted, for example, by a barcode attached to the sample container and read...

Abstract

The present invention lies in the field of automated analyzers and relates to a method for mixing liquids in liquid containers. The arrangement for automated mixing comprises a shaking device (13) and a gripper (11) which is connected by way of a flexible connecting element (36) to a transfer arm (10) and which serves for receiving a liquid container (30). The coupling of gripper (11) and shaking device (13) is realized by way of an eccentrically movable coupling pin (33) and a coupling hole (34) provided for this purpose.

Description

technical field [0001] The invention belongs to the field of automatic analyzers and relates to a method for mixing liquids in liquid containers. Background technique [0002] Current analyzers are capable of performing multiple detection reactions and analyzes on multiple samples, as are routinely used in analytics, forensics, microbiology, and clinical diagnostics. In order to be able to carry out multiple checks in an automated manner, various automatically operated devices for the spatial transfer of measuring cells, reaction vessels and reagent liquid containers are required, for example, transfer arms with gripper function, transport belts or possible Rotating transport wheels, and devices for transferring liquids, such as pipetting devices. The machine comprises a central control unit which, with suitable software, is able to plan and carry out the work steps for the desired analysis largely independently. [0003] Many analytical methods used in such analyzers oper...
