DEVICE FOR TAKING SMEAR FROM UPPER PART OF VAGINA AND PAP SMEAR Russian patent published in 2022 - IPC A61B10/02 

FIELD: medical equipment.

SUBSTANCE: device for taking a smear from the upper part of the vagina and a pap smear, containing a tip, includes an outer cylinder; a head separated into parts in a longitudinal direction in front of the outer cylinder, having an inner side of the head, made flat and thinner for simplification of head output, and an end side curved and thicker for control; the first ring in the end part of the outer cylinder; a spiral end for integration of the outer cylinder, piston lids, and a tip holder. Two, the second and the third, rings connect the spiral end to the piston lid for provision of movement of an inner cylinder. The first inner cylinder is installed with the possibility of free movement inside the outer cylinder. The piston lid engages with the soral end. The fourth ring has a protrusion of 1 mm in the end part for blocking the movement of the first inner cylinder. The first spring is between the second and the fifth ring. The second inner cylinder is closed from the front inside the first inner cylinder, and it has the first hole for head input in a center. The fifth ring rests on the spring. There is a hole in the center for input of the tip holder to the end part of the spiral. The second spring is located in the second inner cylinder. A reverse stroke cylinder serves for pressure transmission to the device for taking a smear from the upper part of the vagina and a pap smear. A square-shaped hole serves for the connection of the reverse stroke cylinder to a spiral on the front side, a circle is for simplification of pushing by a thumb the rear part of the reverse stroke cylinder. A cone prevents reverse retraction of the piston lid. The hole combines the piston lid with the reverse stroke cylinder. A twisted spiral has a square shape inside the reverse stroke cylinder. The sixth ring is located between the spiral and the tip holder. The seventh ring is intended for fixation of the tip holder.

EFFECT: provision of a possibility of self-application of a device.
