Abstract 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 said 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.
Device for taking samples of cells from the cervix, characterized in that it consists of a rod, a conical body having a concave undulated lateral surface and a hemispherical tip, said rod connected to the base of said conical body and extending coaxially with the longitudinal axis thereof, said undulated surface extending from the base of the conical body to the hemispherical tip, the base radius of the cone being 5-15 mm, the radius of the hemispherical tip being 2-4 mm, the radius of the arc defining the concave lateral surface of the conical body being less than 50 mm and the undulated lateral surface approximately defining in cross-section taken through an imaginary conical section normal to said 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 wavelength and amplitude being between 1.5 and 5 mm at the base of the cone.
