Ova detector assembly

Abstract

A device for use in examing fecal matter for presence of ova. The device essentially comprises a cup shaped vial open at one end and an elongated strainer adapted to nest and seat in the vial and a closure cap which may be pivotally connected to the vial. The vial has a mixing blade in its vase and the strainer has a sampler cavity at one axial end with inwardly directed fins which engage over the blade in the fully assembled position so that when a solution is added and a specimen has been accumulated in the sampler cavity of the strainer it may be oscillated relative to the container to effect good mixing and release of ova from the feces. The vial and strainer have interengaging lug and rib means to limit rotation of the strainer in the vial. The vial also is formed with a configuration of openings in a radial wall which have faces which converge downwardly to a sharp edge to ensure smooth and unobstructed flow of ova to the head section of the strainer. The strainer nests loosely in the vial initially for ease of removal of the strainer to accumulate a specimen and thereafter can be seated firmly in place to provide a liquid seal.
