An elongated aspirator tube (20) has a proximate end portion (29) adapted for quick connection to a suction-generating device (33 or 35) for collection of cell-containing mucus from the uterine endocervical canal (9), an a flattened distal end portion (22) forming a spatulate scraper for collecting cells exfoliated from the tranformation zone (5) of the uterine cervix. The scraper includes a frontal lobe (23) through which the bore (21) of the aspirator tube (20) opens, an adjacent lateral lobe (24) abuttable against the ring (11) of the cervix projecting into the vagina for positioning the blunt apertured distal end of the frontal lobe (23) at approximately the external os (6) and a concave transition portion (25) forming a scraping edge joining and faired into the adjacent edges of the two lobes (23 and 24). Mucus from the endocervical canal (9) is aspirated into the tube (20) and the entire transformation zone (5) scraped by rotation of the tube (20) for conection of freshly exfoliated cells to be deposited on a slide (36). |
