LARYNGEAL AIR DUCT WITH ESOPHAGEAL OBTURATOR (VARIANTS) Russian patent published in 2006 - IPC A61M16/04 

FIELD: medicine, clinical anesthesiology, resuscitation of urgent states.

SUBSTANCE: the suggested laryngeal air duct with esophageal obturator contains a double-lumen tube with canal for artificial pulmonary ventilation with sealed distal end, and in front of rima glottides there are respiratory openings, and with canal for introducing gastric probe and leveling the pressure in case of random barbotage with oblique open cutting at its distal end. Tube's active end is embraced with a blowing gasket supplied with air duct; free end of canal for artificial pulmonary ventilation is supplied with standard connector. Air duct contains special device with a fixing clip for fixing the tube including seals for sealing nasal meatuses; the tube is designed to be thermoplastic; air dust is designed to be supplied with a control gasket. Binasal laryngeal air duct with esophageal obturator has got two soft adapter-connected nasopharyngeal tubes designed out of thermoplastic material of different length. Long tube with sealed distal end, blowing gasket is being an esophageal obturator. Short tube with oblique open cutting at its distal end, blowing gasket supplied with air duct with a control gasket is being a respiratory canal. Adapter is supplied with a standard connector. The present innovation provides reliable hermeticity of the contour: air duct - patient's respiratory tract; rapid and atraumatic fixation of the tube and increased safety of a patient.
