Abstract: An apparatus and method is disclosed for supporting a fluid sampling device in an opening below a manhole cover. The apparatus contains a triangular shaped assembly of three tubular members joined together at a common juncture. At least one of the tubular members has an extending member to adapt the triangular shaped assembly to be connected beneath a manhole cover of varying sizes for different sized openings in a street.
Abstract: Lid 12 has affixed thereto an annular resilient flap 26 which cooperates with a flange 21 on a lid support 13 to resist dislodgement of the lid. The flap 26 i worked into position beneath the flange 21 by rotation of the lid about its axis. A container portion 34 of the lid may contain a granular material to add weight to the lid.
Abstract: A biopsy needle assembly that is an improvement over the Jamshidi biopsy needle assembly is provided. The improved biopsy needle assembly includes a cannula with a uniform diameter internal surface defining an inner biopsy tissue sample receiving and retaining bore having projections thereon, and a stylet having rounded edges with at least one V-shaped groove at a distal cutting tip removably received within the bore of the cannula. The projections may be barbs, annular or spiral ribs that line the inner biopsy tissue sample receiving and retaining bore. The stylet may include a quick release knob for engaging with an improved coupling at the proximal end of the cannula. The improved coupling is substantially cylindrical with a cross handle substantially in the middle thereof. The coupling may also include internal threads engaging a syringe. The improved biopsy needle assembly permits more consistent acquisition of an adequate tissue sample for biopsy and is less painful to the patient.
