Device and Method for Automatic Calibration Verification of an Analyzer
First Claim
1. A method for carrying out a verification of the calibration (calibration verification, CV) of a measurement system of an analyzer for determining different measurement parameters in body fluids, comprising the steps of:
- inserting into or docking onto the analyzer a cartridge containing a plurality of identical sets of at least five different measurement fluids with known different measurement parameter values, which are distributed over the total measurement range of the measurement parameters which can be measured by the measurement system, in particular including measurement parameter values at the upper and lower limits of the measurement ranges,reading in the measurement parameter values stored in a storage unit assigned to the cartridge, and other data and information relevant for the CV process of the analyzer to be verified,selecting measurement fluids to be measured according to the data stored in the storage unit,feeding the measurement fluids into the measurement system by the analyzer and measuring them by the analyzer,automatic evaluation of the measurement results by an evaluation unit assigned to the analyzer, taking into account the stored data, andoutput of an evaluation protocol on an output device.

Abstract
A method and a device for carrying out calibration verification (CV process) of an analyzer for determining different measurement parameters in body fluids is provided. The device according to the invention comprises the following components: a cartridge with a plurality of containers, which can be connected to an intake system of an analyzer, each of which contains a measurement fluid with known measurement parameter values; a storage unit assigned to the cartridge for storing the measurement parameter values of the measurement fluids and data relevant for the CV process of the analyzer to be verified; a docking or intake area at or in the analyzer for receiving the cartridge with a data path for reading the storage unit; an evaluation unit typically housed in the analyzer for evaluating the values measured by the analyzer; and an output unit for printing an evaluation protocol.
