  • Patent number: 4620548
    Abstract: An elongated plastic aspirator tube has a proximate end portion adapted for quick connection to a suction-generating device, such as a rubber squeeze bulb or a syringe, for collection of cell-containing mucus from the uterine endocervical canal, and a flattened distal end portion forming a spatulate scraper for collecting cells exfoliated from the transformation zone of the uterine cervix. The spatulate scraper includes a frontal lobe through which the bore of the aspirator tube opens, an adjacent lateral lobe abuttable against the ring of the cervix projecting into the vagina for positively positioning the apertured distal end of the frontal lobe at approximately the external os and a concave transition portion forming a scraping edge joining and faired into the adjacent edges of the two lobes.
