    摘要: A system for detecting and analyzing patient sample quality and/or analytes, while the sample is in the metering tip used to aspirate the sample liquid from an original patient sample container, and also to dispense the liquid onto a slide test element. Spectrophotometric analysis may be done on the sample liquid while it is still in the tip which has been converted into a cuvette. One technique for such analysis is by scanning the cuvette for transmittance in a light-tight enclosure. Near-infrared and adjacent visible radiation may be used, and the absorption spectra of the liquid detected and analyzed. A possible aspect of the present invention relates to enhancing throughput of an analyzer by conducting a sample quality measurement in a process that is parallel to the main analyzer timing cycle. Another possible aspect of the present invention relates to improving performance of the analyzer by sealing the end of the metering tip to spontaneously form a cuvette for holding the sample during the sample quality measurement. Some advantages of the present system and method include improved throughput, the capability to use smaller sample liquid volumes, eliminating any need for a separate supply of cuvettes independent of the metering tips, and providing for detection through a cone of the metering tip rather than through any label, compared to doing the scanning of the sample liquid in a primary patient collection container.

    摘要: A method and apparatus for detecting improper liquid content of a metering tip of an analyzer. The method detects the content or status using radiation between 630 and 2000 nm, and comprises the steps of: a) aspirating the liquid into one of the tips to fill the tip to a nominal level; b) scanning the liquid in the tip by a scanner (16) comprising a light source (18) and a light detector (26), the source and detector being aligned along a direction that is generally normal to the tip axis; c) providing relative motion between the tip and the scanner while the step b) is conducted, so that the scanner scans from a first position below the tip where a pendant drop of the aqueous liquid would be located if present, to a predetermined second position above the first position that represents the nominal level; d) while conducting steps b) and c), separately detecting at each of several portions of the tip between and including the first and second positions, the amount of light transmitted to the detector, so that all liquid-containing levels within the tip are detected; e) comparing the detected light of step d) with light known to be transmitted if liquid is present only at all of the levels, free of air bubbles; and f) flagging the results as being in error if water is detected at the first position; or if it is not detected because of air bubbles at any one of the levels within the tip up to and including the second position; or if it is detected above the second position.

    摘要: Apparatus and a method for mixing a liquid within a disposable aspirating probe tip so that most of the liquid is forced to move past a transition zone between two different inside diameters to cause rotational mixing. The apparatus and method can be used to provide agglutination of blood, which in turn can be used for blood typing. The probe tip can comprise a single integral piece, or two separate portions. The transition zone can comprise a sharp demarcation between inside diameters, or a smooth one.
