PCT No. PCT/SE81/00198 Sec. 371 Date Feb. 18, 1982 Sec. 102(e) Date Feb. 18, 1982 PCT Filed Jun. 30, 1981 PCT Pub. No. WO82/00090 PCT Pub. Date Jan. 21, 1982.Device for taking samples of cells from the cervix for preparation and testing of whether abnormal cells are present in the sample, the device consisting of a conical body (1) with a concave undulated lateral surface (5) and a hemispherical tip (3), the undulated surface extending from the base of the conical body to the hemispherical tip. The base radius of the cone is 5-15 mm. The radius of the hemispherical tip is 2-4 mm. The radius of the circular arc defining the concave lateral surface (5) of the conical body (1) is less than 50 mm. The undulated lateral surface defines in cross section taken through an imaginary conical section normal to the surface, and the apex of which lies on the longitudinal axis of the conical body, a sine curve with decreasing wavelength and amplitude along the circular arc approaching the tip. The amplitude and wavelength are 1.5-5 mm at the base of the conical body. The device is suitably supplemented with a test tube (12) and a screw cap (13 ) fitted thereto, through which the rod (11 ) passes. |
