Abstract

Usage: in medicine, in particular in obstetrics and gynecology, to reduce the morbidity and increase the effectiveness of cytological and colpositological studies. SUMMARY OF THE INVENTION: the device comprises a hollow body, inside of which there is a mechanism for longitudinal movement of the working element, made in the form of a two-shouldered lever pivotally mounted in the body. One shoulder of the lever is rigidly connected to a corrugated plate and a finger holder. The other shoulder is pivotally connected to a rod on which a working element is fixed, made in the form of a cylinder with a corrugated working end. The body has a window in the side wall for withdrawing a corrugated plate from the body and an opening in the working end for removing the working element from the body when collecting diagnostic material from the walls of the vagina and cervix endocervix. 1 s, s, f-ly, 2 ill.

Description

The invention relates to the field of medicine, in particular to gynecology and obstetrics.

The purpose of the invention is to reduce the morbidity and increase the effectiveness of cytological and colpositological studies.

Figure 1 shows the proposed device; figure 2 is a view of figure 1.

The device comprises a housing 1 with a flange 2 and a window 3 in the side wall of the housing. On the rounded working end of the housing 1 there is a through hole 4. Inside the housing 1 there is a translational movement mechanism of the working element 5, made in the form of a cylinder with a corrugated working end. The mechanism of translational movement of the work item contains

two shoulders lever 6, mounted on the axis 7. rotation on the flange 2 of the housing 1. One shoulder of the lever is equipped with a finger holder 8 on the non-working end, on the working end it is rigidly connected to the corrugated plate 9 and spring loaded relative to the housing by the spring 10. The other, shorter shoulder is hinged to the rod 11 and rigidly connected to the working element 5. The second finger-holder 12 is rigidly attached to the flange 2 of the housing 1,

The device operates as follows.

Examined, taking into the device by hand the finger holders 8 and 12, fingers in the open state, without rendering; pressure on them, inserts a tube into the vagina, while the working element 5 and the plate

9 are inside the tube 1. After insertion, the finger holders are closed. In this case, the corrugated plate 9 and the working element 5 extend beyond the housing 1 through the window 3 and the hole 4, respectively, making contact with the walls of the vagina to collect cellular material.

After that, the finger holders are opened, returning to the initial position the plate 8 and the working element 5, which are protected from contact with the environment and contamination of the sample.
