METHOD FOR ARTIFICIAL RESPIRATION IN EXTREME SITUATIONS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC A61H31/02 

FIELD: medicine.

SUBSTANCE: special device is used for artificial respiration, containing two coaxially located bellows, hermetically sealed at the ends by flanges containing handles configured to deform the bellows, and a breathing chamber connected via a flexible duct with the face mask of the victim. Through the valves with internal bellows and inter-bellows space, the volume of the inner bellow and the volume of inter-bellow space are connected via valves to the atmosphere, with a possibility of air entering to the inner bellow and exiting from the inter-bellow space to the atmosphere. At that, the volume of the inner bellow is equal to the volume of the inter-bellow space. During artificial inspiration, the volume of bellows is reduced to fill the lungs with the respiratory mixture from the second bellow, and to vent the respiratory mixture from the first bellow. And during artificial exhalation, bellows volume increases to fill the first bellow with the exhalated respiratory mixture and to fill the second bellow with fresh respiratory mixture for subsequent inhalation. The procedure is repeated until the patient's breathing is restored.

EFFECT: method and the device allow to increase the efficiency of artificial ventilation during resuscitation.
