APPARATUS FOR ARTIFICIAL VENTILATION OF LUNGS AND INHALATION NARCOSIS

摘要

FIELD: medical equipment.;SUBSTANCE: apparatus for artificial ventilation of lungs and inhalation narcosis can be used for emergency service and has unit for artificial ventilation of lungs, anesthetic unit and unit for alarm switch of anesthetic. Unit for artificial ventilation of lungs has oxygen discharge changing unit, flow meter, pneumatic pulse oscillator, nonreversible pneumatic valve which has access to patient's mask. Anesthetic unit has gas relation changing unit and mixer which has access to patient's mask. Unit for alarm switching anesthetic off is made is made in form of comparison unit which has pneumatic valve mounted in anesthetic feed line, two pneumatic relays and two regulators. Apparatus provides improvement in sensitivity to reduction in oxygen pressure in gas mixture.;EFFECT: widened operational capabilities; simplified exploitation; improved safety.;2 dwg
