COMBINED APPARATUS FOR LIQUID SUPPLY TO ENDOSCOPE FOR ENDOSCOPIC IRRIGATION AND LENS RINSING Russian patent published in 2014 - IPC A61B1/15 A61B1/12 

FIELD: medicine.

SUBSTANCE: invention refers to medicine. A method for liquid supply to an endoscope is enabled by means of an apparatus for liquid supply to the endoscope. The apparatus comprises a nozzle for detachable connection to a liquid source. The first tube of the apparatus connects a gas source and a chamber of the liquid source via a liquid medium so as a cavity of the first tube is connected via the liquid medium to the chamber when the nozzle is attached to the liquid source. The second and third tube of the apparatus supply the liquid from the chamber to the endoscope and can pass through the first and second holes in the nozzle respectively, thereby the tube ends are immersed in the liquid when the nozzle is attached to the liquid source. A liquid flow rate through a cavity of the third tube exceeds that through a cavity of the second tube. The apparatus comprises a valve unit to stop the liquid flow from the cavity of the second tube to the chamber. The gas is supplied from its source into the chamber in an amount sufficient to increase pressure in the chamber. The first and second liquid volumes are supplied from the chamber of its source into the endoscope when the pressure increases in the chamber for the endoscope lens rinsing through the cavity of the second tube and for endoscopic irrigation through the cavity of the third tube respectively.

EFFECT: using the invention enables supplying liquid for the endoscope lens irrigation and the liquid for endoscopic irrigation from one liquid source.
