Abstract
Abstract The present invention relates to a device for simultaneously taking samples from both the endocervix and the exocervix, which device is made in one piece and includes a rod, one end of which carries a scraper. According to the invention said scraper is made with its middle part being elongated and narrow so that it may penetrate into the cervical canal for taking samples from the endocervix, whereas the remaining part is sufficiently wide to abut against the cervical wall for taking samples from the exocervix. The elongated and narrow part of the scraper is loop-shaped, whereas the remaining part is wing-shaped and located at both sides of the rod. Furthermore the invention comprises a method for examining the cervix by means of the above mentioned device.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
176 words
A device for simultaneously taking samples from both the endocervix and the exocervix, the device being made in one piece and comprised of a rod having a scraper at one end, the scraper having a middle part which is elongated and narrow and constructed of a material of sufficient rigidity to permit penetration into the cervical canal for taking samples from the endocervix, the middle part having a loop therethrough for capturing a sample, the loop being sufficiently narrow so that a liquid disposed therein has a high surface tension so that the sample is retained within the loop, the scraper also having wing shaped components for taking samples from the exocervix and which flank the middle part, the wing shaped components being constructed of a material which is flexible so as not to damage human tissue but which is of sufficient rigidity to permit the taking of a sample, the wing shaped components being cerrated upon the edge upon which the sample is to be taken in order to facilitate the taking of the sample.
Claim 2
Independent Claim
176 words
A device for simultaneously taking samples from both the endocervix and the exocervix, the device being made in one piece and comprised of a rod having a scraper at one end, the scraper having a middle part which is elongated and narrow and constructed of a material of sufficient rigidity to permit penetration into the cervical canal for taking samples from the endocervix, the middle part having a loop therethrough for capturing a sample, the loop being sufficiently narrow so that a liquid disposed therein has a high surface tension so that the sample is retained within the loop, the scraper also having wing shaped components for taking samples from the exocervix and which flank the middle part, the wing shaped components being constructed of a material which is flexible so as not to damage human tissue but which is of sufficient rigidity to permit the taking of a sample, the wing shaped components being cerrated upon the edge upon which the sample is to be taken in order to facilitate the taking of the sample.
Claim 3
Dependent Claim
27 words
The device as set forth in claim 1 wherein the middle part is disposed substantially at a right angle to the plane constituted by the wing-shaped components.
Claim 4
Dependent Claim
21 words
The device as set forth in claim 2, wherein the wing-shaped components of the scraper are knurled on their upper side.
Claim 5
Dependent Claim
122 words
Method for examining the cervix, wherein the device of claims 1, 2 and 3 is introduced into the vagina so that the narrow middle part of the scraper is inserted into the cervical canal, whereas the wing-shaped components of the scraper abut against the cervical wall, and rotation of the rod of the device by the sample taker causes samples of cells and tissue of the endocervix and the exocervix to be collected by the scraper at the middle part and upon the wing shaped components after which the device is removed from the vagina for preparing a smear of the endocervix on a slide and the same of the exocervix on another slide, after which both smears are subjected to examination.
