PROBE FOR PASSING CHANNELS (OPTIONS) Russian patent published in 2021 - IPC A61M25/00 

FIELD: medical technology.

SUBSTANCE: group of inventions relates to medical technology, it is intended for the study of hollow spaces in horizontal, vertical and inclined directions, straight or having a complex curved shape, a variable amount of lumen, as well as for filling the cavities between the piston and the cylinder, valves, rods and other cylindrical mechanisms with reciprocating motion for the purpose of their protection, lubrication, sealing and heat dissipation. The probe for the passage of channels contains an elastic elongated shell. The shell is toroidal and has two axially arranged walls. The shell is made of a flat plate wrapped on itself and glued at the end. A cavity is formed between the outer and inner walls, in which elastic rings are installed at an equal distance, perpendicular to the axis of the shell. In the second embodiment, the probe for the passage of channels contains an elastic elongated shell. The shell is toroidal and has two axially arranged walls. The shell is made of a flat plate wrapped on itself and glued at the end. A cavity is formed between the outer and inner walls, in which an elastic pipe is installed. In the third embodiment, the probe for the passage of channels contains an elastic elongated shell. The shell is toroidal and has two axially arranged walls. The shell is made of a flat plate wrapped on itself and glued at the end. A sealed cavity is formed between the outer and inner walls, which is subjected to the pressure of an elastic medium or is under vacuum.

EFFECT: use of the inventions makes it possible to increase the length of the probe passage through channels with different shapes and sizes.
