摘要：
FIELD: medicine.SUBSTANCE: claimed is a device for the formation of a required concentration of liquid anaesthetics in anaesthetic apparatuses, containing a mixing-and-evaporating chamber, a reservoir for a liquid anaesthetic, connected by a hydraulic main line with the mixing-and-evaporating chamber by means of a shutoff-and-pass valve and a jet. The shutoff-and-pass valve is electrically connected to a command-and-control electronic unit. The device also contains a microcompressor of the pressure boost of air into the said reservoir and a sensor of pressure control in the reservoir for the liquid anaesthetic. Claimed is a method for the formation of a required concentration of anaesthetics in evaporators of anaesthetic apparatuses in carrying out low-flow anaesthesia, in which the injection of a liquid anaesthetic is realised by a doser of anaesthetics directly into the breathing gas flow. Injection is realised by discrete single doses. The volume of a discrete single dose of injection is set by the ratio: where Vp is the volume of a discrete single dose of the liquid anaesthetic, supplied in each injection Qa is the estimated total flow of the liquid anaesthetic, injected per the time unit, required for the provision of a specified concentration of anaesthetic vapours in the breathing mixture Fmax is the frequency of the discrete doses of injections per the time unit, which is technically maximally achievable by the doser of anaesthetics.EFFECT: inventions provide the accuracy of dosing the vapours of liquid anaesthetics in the wide range of changes of their concentrations and flows of the carrier-gas in carrying out low-flow anaesthesia.2 cl, 1 dwgГруппа изобретений относится к медицине, а именно к анестезиологии и реаниматологии, и может быть использована при проведении низкопоточной анестезии.
