(54) DEVICE FOR COLLECTING DIAGNOSTIC MATERIAL OF THE Cervix

The invention relates to medical equipment and can be used to extract cellular tissue structures during gynecological examinations.

A device for collecting diagnostic material of the cervix, containing a handle passing into the shaft, and the working part of the conical shape [1].

However, the known device does not provide simultaneous collection of surface epithelium from all areas of the cervix.

The purpose of the invention is the simultaneous collection of surface epithelium from all areas of the cervix.

This goal is achieved by the fact that the device for collecting diagnostic material of the cervix contains a handle that goes into the shaft, and a conical-shaped working part, the cone of which is made with a cup-shaped side having a radius bend, and the cone and cup-shaped side are perforated.

The drawing is schematically depicted. device for collecting diagnostic material of the cervix.

The device comprises a handle 1, which passes into the rod 2 and the conical shape of the working part, the cone 3 of which is made with a cup-shaped bead 4 having a radius bend 5, and the cone and the cup-shaped bead made with holes 6 with a diameter of 0.5-1 mm.

The device operates as follows.

When sampling the cellular material, the device is held by the handle 1, which passes into the rod 2, and is introduced into the moisture. moreover, until the working part comes in contact with the cup-shaped bead 4 with the entire surface of the cervix, as a result of which soft tissues of the cervix fill the holes 6.

After the introduction of the device, it is rotated around its own axis on

83949 (3 angle 90-360, depending on the density of the holes on the cup-shaped side 4. The edges of the holes 6 exfoliate the cells from the surface of the cervix and the cells move from the holes 6 to the inner surface of the cup-shaped side 4.

The next operation is to remove the device from the vaginal cavity · and transfer the cellular material either to a glass or into a suspension.

To do this, cone 3 is immersed in a vessel with a fixing liquid, intensively rotate the device around its axis, thereby rinsing and separating the cells from each other. Then the device is removed from the suspension and, if the cone 3 is made of metal, the device is sterilized by boiling, if the cone 3 is made of plastic, only rod 2 is removed and sterilized, and I put on a new cone 3.

The proposed device allows one-time obtaining surface epithelium from all areas of the cervix.

This ensures efficient cell collection and significantly increases the accuracy of the cytological diagnosis by eliminating the omission in the study of the cytological section of the cervix, and also allows the collection of cellular material for the diagnosis of cervical cancer and other diseases.

Claims (1)

(54) DEVICE FOR COLLECTION OF DIAGNOSTIC MATERIAL OF THE CERVIX The slugging operation is to remove the device from the vaginal cavity and transfer the cellular material either to a glass slide or into a suspension. For this, the cone 3 is immersed in a wasp with a fixing fluid, the device is intensively rotated around the axis, thereby rinsing and separating the cell from each other. Then the device is removed from the suspension and, if the cone 3 is made metatactic, then the device is sterilized by boiling, if the cone 3 is made of plastic, then only rod 2 is sterilized and the cone 3 is dressed new. The proposed device allows one-time treatment of superficial epithelial lilius from all areas of the cervix. This provides an efficient collection of cells and significantly increases the cytolygic diagnosis by eliminating the omission in the study of the cervical cytoloptic site, and also allows for the collection of cellular material for the diagnosis of cervical cancer and other diseases. Formula of an Invention Retentive Device For collecting diagnostic material of the cervix, containing a handle that passes into the stem and the working part of a conical shape, which is due to the fact that, in order to simultaneously collect the surface epithelium from all areas of the cervix, a bowl-shaped side having a radial limb, and the cone and bowl-shaped bead are made perforated.
