  • Patent number: 5715082
    Abstract: A microscope attached slide dotting device includes a clamping ring arranged for selective mounting onto a microscope barrel having an objective lens. The clamping ring includes cooperative first and second semi-cylindrical members arranged for clamping about the microscope barrel. The second semi-cylindrical member employs a mounting boss provided with opposed dovetail projections slidably and complementarily received within a slide plate. The slide plate includes opposed first plate flanges to receive the dovetail projections projecting from a first side of the slide plate, with a second side of the slide plate projecting at a dovetail boss for complementary and slidable reception within a housing recess of an associated marker housing. The marker housing includes a marker assembly extending through the marker housing. A plurality of clamping members permits orthogonal and slidable relationship of the marker housing relative to the clamping ring via slide plate.

  • Patent number: 5422273
    Abstract: An apparatus for use in the efficient collection of cell samples from a cytology brush device. The device is a cylindrical container capable of containing a solution. The open end is sealable with a removable cap. The closed end of the container is formed as a conically shaped end and disposed within the conically shaped closed end is a series of fins. The fins are oriented so as to form a fin passageway, which is capable of receiving the bristled portion of a cytology brush. When the cytology brush is rotated, the bristles are agitated against the fins, thus dislodging cell samples. The cell samples are then dispersed within the solution and later retrieved. Disposed at the open end of the container is an insert. The insert has an alignment opening which acts to keep the trailing end of the cytology brush aligned with the leading bristled end of the brush, as it is being rotated within the fin passageway.
