ABSTRACT:
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.
