摘要
An improved anaesthetical circuit with reverse inhalation is equipped with an injector of escaped anaesthetics connected by an inlet pipe to a valve in which a feeding pipe, leading from a source of constant flow, discharges a signal from a differential pressure indicator, being led into the valve through a conduit. The differential pressure indicator is fed from an energy source, on one hand, together with a conduit pipe leading from a drive pipe into the pressurized chamber of the differential pressure indicator, and a pipe leading from a connection pipe into the vacuum chamber of the differential pressure indicator, on the other hand. A connection pipe connecting an outlet pipe of the injector through a check valve with a rubber bag, which is arranged in a cylinder attached to the anaesthetical circuit. A drive pipe leading into the cylinder, containing the rubber bag and a pipe, leading from the drive pipe, leads into a control chamber of an expiration valve, the outlet pipe of which leads into a distribution valve. The distribution valve has two branches, one branch of it forming an exhaust system provided by a check valve leading out from the anaesthetical circuit, and the second branch of the distributor valve forming a runback pipe which is equipped with a pressurized valve which is connected through a carbon dioxide absorber and through a check valve to the connection pipe leading into the vacuum chamber.
