  • Patent number: 8470268
    Abstract: An apparatus for collecting oral fluid, comprising a vial formed with an inner specimen receptacle for receiving the oral fluid. The open top of the vial is cylindrical and formed with threads on a portion of its outer surface adjacent its open top. The specimen receptacle is disposed within the vial, spaced along its length from the inner surface of the vial and has a closed bottom end and an open top end. The entire periphery of the receptacle top end is sealingly secured to the inner surface of the vial proximal to but spaced from the vial's open threaded end. The bottom end of the vial can be open and flat and extend beyond the closed end of the specimen receptacle to enable the vial to be set on a horizontal surface. A funnel is removably placed in the open top end of the vial and narrows to an inner neck fits within the open top end of the vial.

  • Publication number: 20070299363
    Abstract: An apparatus and method for concentrating parasitic eggs and/or larvae from a fecal sample using a single tube by extruding the fecal sample through a strainer using a cap plunger device into a centrifuge tube containing 10% buffered formalin or equivalent fixative. After mixing and fixation, the strainer device is removed, and ethyl acetate and a surfactant are added. After mixing, the extruded sample is centrifuged to concentrate parasite eggs and/or larvae at the bottom of the centrifuge tube.

  • Patent number: 6931821
    Abstract: A tamper evident cap assembly, more particularly a combination of vial and cap assembly, assures the integrity of a specimen and of the specimen collection process. The screw cap is locked to the screw threads of a vial, when the vial is empty, with one of two latches that are integral to the cap assembly and can lock the cap to the vial. The lock is broken in the presence of the specimen donor or in the presence of a witness who can testify as to chain of custody, a specimen is placed in the vial, following which the cap is locked to the vial with the other of the two latches, which is broken when received by a testing laboratory. A loop formed to encircle the vial is connected by a tether to the cap and slipped onto the vial. At least one restraining rib on the vial is spaced below the screw thread top and is sized to permit the loop to be forced upwardly thereover to be restrained from downward movement.

  • Patent number: 5922289
    Abstract: A microtitration tray for carrying a plurality of frangibly-collected multi-well linear strips in circular apertures therefore, in which the effective diameter of the aperture is reduced by a plurality of symmetrically projecting protuberances, such as ribs, so as frictionally retain the wells in the apertures while enabling ready release of the wells therefrom.

  • Patent number: 5540331
    Abstract: A solvent-leak-proof container for rectangular microscope slides includes a thermoplastic vial formed with a threaded cylindrical end and a removable threaded mating cap. The cap includes a centrally disposed cylindrical sealing member for leak proof sealing against the threaded end of the vial. The vial interior includes opposing pairs of longitudinal ribs for supporting and positioning rectangular microscope slides within the vial. The body of the vial is circular at least at the threaded end mating with the cap, but is generally rectangular thereafter to form opposing pairs of flat gripping surfaces which are also suitable for marking the vial for identification.

  • Patent number: 5131158
    Abstract: A gauge for validating the inner diameter and thickness of a calibrated loop. The gauge preferably has a long handle, a cylindrical member at each end of the handle and a slot at each end of the handle. The cylindrical members have slightly different outside diameters for attempted insertion into the loop to be validated and the slots have slightly different widths for attempted insertion of the loop therein. Identifying indicia are imprinted on the handle to indicate which end is which.

  • Patent number: 5063026
    Abstract: A collecting apparatus for the collection of pinworm eggs incorporates a shaft surrounded by an adhesive strip. A tab is disposed at the free end of the adhesive strip. The shaft is attached to a gripping member by a connecting member.The gripping member is preferably a threaded screw cap suitable for use with a storage tube. The shaft and connecting member are placed within the tube and the tube is sealed with the gripping member for transportation and storage of collected eggs. Once a specimen is collected, the tab of the adhesive strip is used as an anchor. Using the gripping member as a tool in a rotating fashion, the entire adhesive strip is rolled onto a microscope slide without disturbing any specimens on the strip.

  • Patent number: 4892831
    Abstract: An inoculating device having an inoculating loop, an improved streaking portion and a picker. The device is constructed of high impact polystyrene material which is injection molded to form a long thin member. One end of the device comprises a loop. The other end of the device forms a head having a plurality of distinct streaking surfaces. In the preferred embodiment, these distinct streaking surfaces have a convexity and come together to form a common point or apex, for example as in a curved pyramidal shape.

  • Patent number: 4782977
    Abstract: A container defined by a base and cover, with the cover being formed to fit upon the base. The base and lid are formed so that when fitted together at least one wall of each overlaps a wall of the other. The overlapping walls are formed with an aperture which become aligned when the cover and base are fitted together. The container further includes a fastening hasp attached to either the cover or the base. One end of the hasp end is formed to pass through the aligned apertures in only one direction. Once the hasp end is positioned through the aligned aperture any attempt to remove the hasp therefrom brings a portion of the hasp into contact with the wall defining the aperture. This prevents the removal of the hasp from the aligned apertures. The hasp is further formed with a tab which can be grasped and pulled causing the hasp to tear along a pre-scored line.
