Abstract
Abstract An apparatus adapted to be self-administered for obtaining surface cells from a human being, particularly from the vaginal and cervical areas of a female, for use in diagnosing cancer, the apparatus having a spatulalike scraper of heartlike configuration with two dissimilarly shaped lobes for taking a cellular smear, the scraper telescoping within a protective cover and being operable to be extended therefrom and to be rotated for cell collecting when the apparatus is disposed within the human body.

An apparatus for obtaining cells for cytologic examination, comprising: an elongated body member having a central axis with a generally flexible scraper portion at one end of the body member and a handle at the opposite end, disposed between and integral with the scraper portion and the handle is an intermediate portion, the scraper end being formed of substantially nondeformable material defining a flat section and two lobe sections, the two lobe sections are of differing shape and each extends outwardly from the elongated body member defining a plane passing through the axis of the elongated body member, the lobes being of greater thickness in a direction extending transversely to the plane than the flat section joining the lobes and integrally connecting the lobes to the intermediate portion, the lobes having a rough grained surface texture for obtaining cells, the intermediate portion having a flexible portion extending from the scraper end to a cylindrical portion extending therefrom to the handle, the handle having a circular croSs section and protruding gripping ribs disposed about the circular periphery, the ribs extending in length in the direction of the axis of the elongated body member, the handle having an index tab protruding from the circular periphery of the handle outwardly beyond the gripping ribs; and a tubular cover slidably engaging the elongated body member at the cylindrical portion, the tubular cover having protruding positive gripping ribs about its periphery, the ribs extending in length in the direction of the axis of the elongated body member, the elongated body member being slidable between a retracted position whereat the scraper portion is disposed substantially interiorally of the tubular cover and an extended position whereat the scraper portion is disposed substantially exteriorally of the tubular cover for rotational manipulation of the handle and the lobes at the scraper portion when the apparatus is disposed for obtaining cells for cytologic examination.
