FIELD: medicine.

SUBSTANCE: invention concerns medical equipment and can be used at carrying out of an inhalation narcosis on the closed rebreathing system. The system includes a line of giving of a oxygen-narcotic admixture, the apparatus of artificial ventilation of the lungs, a line of the fulfilled oxygen-narcotic admixture, the adsorber of the carbon dioxide established in a line of the fulfilled oxygen-narcotic admixture, a rubber bag and a regulator of oxygen supply. The regulator of oxygen feeding is executed in the form of the locking membranous valve; its cavity under the membrane is bound by an input to a source of fresh oxygen through the locking element, and an exit - with a line of supply of an oxygen-narcotic admixture of the closed rebreathing system.

EFFECT: invention allows carrying out automatic compensatory input of oxygen in a line of oxygen-narcotic admixture supply of the closed rebreathing system.
