Abstract
Abstract In a device for obtaining a smear sample from a body cavity, in particular the uterus mouth or cervix, a plurality of substantially parallel flexible bristles (3) is connected to a carrier (2) provided at one end of a stem (1). In order to ensure that cells from all the portions of the body cavity are sampled the bristles (3) extend substantially parallel to the stem (1) and the bristles (3) each have at least one longitudinal sharp edge (6). The said sharp edge (6) is adapted to scrape cells from the body cavity when the device is rotated about the stem axis.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
78 words
Device for obtaining a smear sample from a body cavity, in particular the uterus mouth or cervix, comprising a plurality of substantially parallel flexible bristles connected to a carrier provided at one end of a stem, characterized in that the bristles extend substantially parallel to the stem and the bristles each have at least one longitudinal sharp edge, with which it is enabled to scrape cells from the body cavity when rotating the device about the stem axis.
Claim 2
Dependent Claim
78 words
Device for obtaining a smear sample from a body cavity, in particular the uterus mouth or cervix, comprising a plurality of substantially parallel flexible bristles connected to a carrier provided at one end of a stem, characterized in that the bristles extend substantially parallel to the stem and the bristles each have at least one longitudinal sharp edge, with which it is enabled to scrape cells from the body cavity when rotating the device about the stem axis.
Claim 3
Dependent Claim
32 words
Device according to claim 1, characterized in that the free ends of the bristles in the transverse centre of the device protrude beyond those of the bristles disposed outwardly of the centre.
Claim 4
Dependent Claim
26 words
Device according to claim 1 or 2, characterized in that the bristles disposed in the transverse centre of the device are thicker than the remaining bristles.
Claim 5
Dependent Claim
36 words
Device according to one of the claims 1-3, characterized in that the carrier at the side facing the bristles has a curved configuration which is adapted to the shape of the mouth of the body cavity.
Claim 6
Dependent Claim
20 words
Device according to claim 4, characterized in that the bristles disposed outwardly of the centre have substantially the same length.
Claim 7
Dependent Claim
17 words
Device according to one of the preceding claims, characterized in that the carrier has an elastic construction.
Claim 8
Dependent Claim
22 words
Device according to one of the preceding claims, characterized in that the carrier has a narrow configuration when viewed in longitudinal direction.
Claim 9
Dependent Claim
39 words
Device according to one of the preceding claims, characterized in that the sharp edge of the bristles are directed such that the bristles are adapted to exert a scraping action in only one direction of rotation of the device.
Claim 10
Dependent Claim
44 words
Device according to claim 7 or 8, characterized in that the bristles at one side of a longitudinal plane extending through the stem axis are rotated 180° about their longitudinal axis with respect to the bristles at the other side of the longitudinal plane.
Claim 11
Dependent Claim
20 words
Device according to one of the preceding claims, characterized in that the bristles are substantially half round in transverse section.
Claim 12
Dependent Claim
16 words
Device according to claim 10, characterized in that one longitudinal side of each bristle is flat.
Claim 13
Dependent Claim
30 words
Device according to one of the claims 1-11, characterized in that the carrier with the bristles is substantially symmetrical with respect to a longitudinal plane extending through the stem axis.
Claim 14
Dependent Claim
32 words
Device according to one of the claims 1-11, characterized in that the carrier at one side of a longitudinal plane extending through the stem axis terminates shorter than at the other side.
