    摘要: A cassette for supporting a plurality of cylindrically-shaped containers (e.g., test tubes) of randomly varying diameters in spaced parallel relationship includes a frame supporting a plurality of tube centering assemblies in side-by-side relationship. Each tube-centering assembly comprises a housing defining a through opening for receiving a container, and a pair of cooperating collar members slidably mounted on the housing for movement towards and away from each other. Each of the collar members has an arcuate surface adapted to contact a side wall of a received container during the sliding movement thereof. A spring is provided to bias the collar members towards each other and towards engagement with the side wall of a received container, whereby the collar members cooperate in supporting a received container therebetween.

    摘要: The invention provides a tube adapter for use on a plurality of different types of tubes. The tube adapter includes a sleeve in which to receive smaller diameter tubes. The sleeve preferably includes a bar code reader slot to allow reading of bar codes on the tubes through the sleeve. The sleeve includes a spring portion biased to retain tubes in the tube adapter. The sleeve also preferably includes a key for aligning the tube adapter in a tube cassette. The tube adapter can include a clip to prevent the tube adapter from inadvertently being removed, rotated or dropped from the tube cassette.

    摘要: A self-adjusting tube detector for operating on a plurality of different types of collection containers or tubes including a pivotable adjustment arm which is biased into a first position. The first position is preadjusted for the smallest diameter tube to be utilized. When a larger tube is moved into the aspiration location, the adjustment arm is moved upward against the bias by the tube. The self-adjusting tube detector includes a pivotable reader arm, which is biased into a first position indicating the absence of a tube in the aspiration location. When a tube passes the adjustment arm, the tube will move the reader arm upward to provide a signal indicating that a tube is aligned in the aspiration location for aspiration by the stripper plate assembly.

    摘要: An aspiration apparatus primarily including a biohazard-safe aspirating cartridge assembly for use with material which might be hazardous to humans. The cartridge assembly includes a longitudinally expandable and contractible washing chamber, within which a fluid aspirating needle is longitudinally positioned. Opposite ends of the washing chamber are secured to a pair of telescopically slidable mounting members, which are pluggably mountable to an operably associated support. A locking element surrounds one of the mounting members, for preventing accidental/premature telescoping. Intentional release of the locking element enables the pair of slidable members to be telescoped together by the drive means, causing the washing chamber to contract, permitting the tip of the aspirating needle to be extended out of the chamber, for penetration of an operably associated sealed container of material, for example whole blood.
