SELECTIVELY MOVABLE VALVES FOR ASPIRATION AND IRRIGATION CIRCUITS Russian patent published in 2020 - IPC A61M1/00 A61F9/07 A61M3/02 

FIELD: medical equipment.

SUBSTANCE: invention relates to aspiration contour of jetting system for selective control of aspiration. Circuit comprises an aspiration manifold operatively connected to the surgical instrument. Circuit includes a displacement pump to create an aspiration flow in the aspiration line. Circuit has an aspiration discharge line operatively connected to said displacement pump. Circuit comprises a Venturi reservoir. Circuit comprises a selectively controlled valve functionally connected to an aspiration main line, a Venturi reservoir and an aspiration discharge line. Selectively adjustable valve is made with possibility of selective installation into position: a) at least a partial fluid connection of the aspiration main line with a Venturi reservoir or with an aspiration discharge line; or b) not passing a flow through said selectively controlled valve.

EFFECT: technical result is reduced wave curve sharpening curve, reduced dependence on elastomer material, reduced response time, reduced acoustic noise, reduced cost and simplified surgical system.
