DEVICE FOR BREATHING Russian patent published in 2007 - IPC A61M16/12 

FIELD: medical equipment.

SUBSTANCE: device for breathing has connecting pipes of breathing mixture components sources are connected with inputs of selector for choosing of components of breathing mixture through reducer. Output of selector is connected with input of pressure regulator for compensating aids and with input excess pressure regulator in breath-out valve of mask. Connecting pipes are also connected with inputs of mixer through breathing mixture components feed speed regulator. Output of oxygen-containing gas source selector is connected with mask through button of alert feed of oxygen-containing gas and with first input of mixer through oxygen-containing gas feed speed regulator. Output of mixer is connected with mask, with output of back valve of additional breath-in and with negative connecting pipe of differential pressure detector. Positive connecting pipe of differential pressure transducer is connected with output of excess pressure value regulator in breath-out valve of mask and with input of mask's breath-out valve. Output of pressure regulator for compensating aids is connected with compensating aids type selector. Control unit is made for automatic selection of breathing mixture components and of type of compensating aids independently on regulation of feed speed of breathing mixture components and of oxygen-containing gas, independently on relation of excess pressure in mask and in compensating aids and alert pressure drop in compensating aids as well.

EFFECT: improved efficiency of operation.
