Description

The utility model relates to the field of medicine, namely to devices for taking diagnostic samples, and can be used, for example, in gynecology for collecting biological material (epithelial cells, biological fluids, microbial bodies) in the axils of the cervical canal, in the cervical transitional zone and from the mucous membrane of the uterine cavity in order to conduct diagnostic studies to determine the precancerous and cancerous condition, including endometrial cancer, as well as the hormonal composition of the uterine mucosa.

Currently cytobrushes made from polymeric materials are widely used in obstetric and gynecological practice.

According to the existing practice, in order to obtain vaginal discharge, the use of cytobrushes in many cases does not allow collecting the number of tissue cells necessary for analysis. It is necessary to take a detachable cytobrush and gynecological spatula with sequential manipulations, which creates discomfort for the patient, or even makes it difficult for the tissue to be taken. The surface of the fibers of the cytobrush and its shape do not always allow to take tissue cells in the sinuses of the cervical canal, and never in the transitional zone of the cervix, for which an additional gynecological spatula is used.

From the "prior art" is known a device for collecting material from the cervix for cytodiagnostics, containing a handle and a working body. In this case, the handle and the working body are made of high-pressure polyethylene, and the working body consists of 69 parallel bristles attached to the arcuate base of the handle, and the general shape of all bristles is a parallelepiped (see RF Patent No. 87077, publ. September 27, 2009).

In addition, from the "prior art" is known a device for collecting material from the cervix for cytodiagnostics, containing a handle and a working body. In this case, the working body contains fixed bristles, and the general shape of all the bristles is a paraboloid of rotation (see RF patent №96480, publ. 10.08.2010).

The technical problem is that there is difficulty in retaining biological material after removing the device and preparing it for research when separating the working body from the handle and placing it in the transport tube.

The task of this utility model is to eliminate the listed disadvantages.

The technical result consists in holding the tissue of a liquid and thick mucous structure after removing the device and preparing it for research by separating the working organ from the handle and placing it in a transport tube or in a container with a stabilizing solution for liquid cytology.

The technical result is ensured by the fact that the gynecological brush for cytological examination includes a handle and a working body, which contains a base with vertically fixed parallel bristles of various lengths in several rows. In the central part of the base there is a brush with bristles fastened in a spiral, and the handle contains a sleeve adapted to move along the handle in the direction of the working member and interact with the base of the working member to separate the working member from the handle.

In accordance with the particular cases of the execution of the device has the following features.

The rows of bristles are located on the sides of the brush, while the rows of bristles, the base and the handle are made of high-density polyethylene.

The brush is twisted from steel wire with helically arranged nylon filament bristles and is formed on the basis of a truncated straight circular cone, with the diameter of the upper base, the diameter of the lower base and the height of the truncated cone refer to each other as 0.7: 3: 4, and the bristles have an uneven surface along the length; in addition, the brush bristles at an angle come into contact with the adjacent brush of the bristles and the vertical bristles of the base.

The diameter of the upper base of the brush is 3.5 mm, the diameter of the lower base is 15 mm, and the height of the truncated straight circular cone is 20 mm.

The brush is made with a length of 204.5 mm.

The length of the brush exceeds the length of the longest vertically fixed bristle of the base.

The essence of this utility model is illustrated by the illustration, which displays the present device for the collection and retention of mucous material for analysis.

The illustration shows the following design elements:

1 - handle;

2 - working body;

3 - base;

4 - vertically fixed bristles;

5 - brush;

 6- sleeve.

 The gynecological brush for cytological examination includes a handle 1 and a working body 2, which contains a base 3 with parallel bristles 4 vertically fixed on it, of various lengths in several rows. In the central part of the base 3 there is a brush 5 with bristles fixed in a spiral, and the handle 1 comprises a sleeve 6 configured to move along the handle 1 in the direction of the working member 2 and interacting with the base of the working member 2 to separate the working member 2 from the handle 1. Working The organ 2 has in the lower part of the base 3 a protrusion of cylindrical or conical shape, which is inserted into the hole at the end of the handle 1 with the fixation of the working body 2 on the handle 1. The above technical features allow you live tissue fluid and thick mucous structure after removing the device and in its preparation for research by separating the working body 2 from the handle 1 and placed in a transport tube or in a container with a stabilizing solution for liquid cytology. The biological material is effectively held between the vertical bristles 4 and the brush of the brush 5. The working body 2 is practically not subjected to mechanical impact when separated from the handle 1, except for the rear surface of the base 3, which interacts with the sleeve 6.

The rows of vertical bristles 4 (up to 5 rows) are located on the sides of the brush 5, while the rows of bristles 4, the base 3 and the handle 1 are made of high-density polyethylene. Vertical bristles 4 are made of different lengths. Setae 4 with a maximum length located closer to the central part of the base, and vertical setae 4 with a smaller length closer to the end portions of the base 3.

The brush 5 is twisted from steel wire with helically arranged nylon filament bristles and is made with a shaping on the basis of a truncated straight circular cone. The diameter of the upper base, the diameter of the lower base and the height of the truncated cone refer to each other as 0.7: 3: 4, and the bristles have a non-smooth surface along the length. In addition, the brush of the brush 5 at an angle in contact with the adjacent brush of the bristles and the vertical bristles of the base 4.

The diameter of the upper base of the brush 5 is 3.5 mm, the diameter of the lower base is 15 mm, and the height of the truncated straight circular cone is 20 mm.

The brush is made with a length of 204.5 mm. The handle 1 has a cylindrical shape, on the free end of the handle 1, opposite to the end with the working body 2, a stopper can be made to prevent the sleeve 6 from falling off the handle 1.

The length of the brush 5 exceeds the length of the longest vertically fixed bristle of the base.

The device is used as follows.

Before taking scrapings, you must examine the cervix in the mirrors. When visually normal cervix is necessary to estimate the amount of mucus on the surface of the cervix. With a significant amount of mucus, the latter is gently removed with a soft cotton swab by lightly getting wet. At the same time sterile packing of a brush is opened.

The brush is inserted into the vagina under the control of the eye, and carefully guided into the cervical canal. It is very important to correctly insert the brush into the cervical canal, since The quality of scraping depends on the insertion of the device into the cervical canal. After inserting the brush into the cervical canal, it is pressed against the surface of the cervix and circular movements are performed: clockwise and then counterclockwise. After that, the device is removed from the vagina, the sleeve 6 moves along the handle 1 to the base 3 of the working body 2, interacts with the lower surface of the base 3 to separate the working body 2 from the handle 1.

Next, the working body 2 is placed in a transport tube or in a container with a stabilizing solution for liquid cytology.

This device for examination of the cervix is contained in a sealed package, is disposable, immediately usable and does not need additional treatment. Practice has shown that when using the device, the possibilities of collecting the cervical canal in the sinuses, in the transitional zone of the cervix are improved, and the tissue of the fluid and thick mucous structure between the vertical bristles and the brush of the bristles is retained. Thus, there is no need to use an additional gynecological spatula, and the procedure is simplified and becomes less unpleasant for the patient.

The brush is intended for taking smears for cytological examination from the entire surface of the cervix and from the cervical canal at the same time:

- from the outer part of the cervix (ectocervix cell),

- from the transformation zone (T-zone),

- from the cervical canal (endocervix cells).

Especially effective for cytological screening for cervical cancer. The resulting material can not only be applied directly to a glass slide, but also used for liquid cytology.
