An apparatus for supplying respiratory gas to a patient in which respiratory gas components are metered with great accuracy and sources of error are detected early. The apparatus has metering devices for respiratory gas components which are connected, on the leading side of a mixing chamber volume, to a ring line; a first respiratory gas analyzer on the trailing side of the mixing chamber volume; a second respiratory gas analyzer at a patient connection; a regulating device for the respiratory gas components which controls the delivery of respiratory gas components, as a function of the concentration measured with the second respiratory gas analyzer, in such a way that the difference between a predetermined concentration and a measured concentration at the patient connection is minimized; and means for performing a plausibility comparison between the measured values of the first respiratory gas analyzer and the second respiratory gas analyzer.

A pressure-resistant tank for liquids includes a plurality of differently shaped diecast parts () made of a first aluminum alloy (cast alloy). The diecast parts () are connected by means of a closed weld seam welded with an electron beam with the use of a second aluminum alloy (wrought alloy). The second aluminum alloy has especially a hydrogen content of less than 0.2 mL per 100 g of wrought alloy. The tank for liquids is especially an anesthetic tank and the anesthetic is desflurane.

An apparatus for medical fluid delivery is to be improved for the sake of simple monitoring of the quantity of medical fluid delivered. For attaining this object, a safety device () with a patient model () is provided, which from past values and current values of the dosage rate of the medical fluid extrapolates a future medical fluid concentration () and switches off the dosage unit () for the medical fluid if the extrapolated medical fluid concentration () exceeds a predetermined limit value ().

Apparatus for controlling the delivery of medical fluids

An alarm is associated with a device for dispensing volatile anesthetics. The alarm and device is designed such that an alarm is triggered whenever the operating voltage is interrupted and an assembly unit that determines the dispensing of at least one anesthetic is not in a prescribed state of operation.

The interaction between a filling valve () on the filling device and an adapter valve on a bottle adapter has improved anesthetics filling features including radially inwardly directed bars (), which engage (pass into) corresponding slots on the outlet pipe of the bottle adapter. The bars engaged in the slots actuate the adapter valve. The bars are provided on the inner wall of a filler neck ().

Filling system for an anesthetic evaporator

A filling system for an anesthetic evaporator is improved such that an anesthetic-specifically coded adapter neck () of a bottle adapter () can be introduced into the filler neck of a filling device. An outer polygon () is provided on the bottle adapter and an inner polygon designed correspondingly thereto is provided on the filler neck as anesthetic-specific codings.

A device for metering anesthetic is provided such that a new anesthetic is immediately available for the metering when the anesthetic is changed. The metering device has an assembly unit that can be removed from the medical apparatus as a module with a reservoir () for a liquid anesthetic, an intermediate container () arranged downstream of the reservoir (), a metering gas source () connected to the intermediate container () and a metering element () for anesthetic on the discharge side of the intermediate container (). An evaporator chamber () may be provided for evaporating the metered anesthetic. A connecting device lets through at least anesthetic vapor as an interface between the assembly unit () and the medical apparatus ().

Metering device for anesthetics

An improved respirator with a breathing circuit ( ) and a corresponding process for operating the respirator are provided. Defined breathing gas volumes can be delivered to the patient and the current operating state can be reliably monitored despite a strong breathing gas volume flow being delivered in the breathing circuit ( ). A gas delivery element ( ) designed as a rotary compressor is connected on the inlet side to a reversible breathing gas reservoir ( ) and on the outlet side to a patient connection piece ( ) for inspiration via a first gas volume flow sensor ( ) with a first nonreturn valve ( ). A second gas volume flow sensor ( ) is located in the connection line between the patient connection piece ( ) and the patient being inspirated. The patient connection piece ( ) is connected for expiration to a second nonreturn valve ( ) via a third gas volume flow sensor ( ) and to the reversible breathing gas reservoir ( ) via a controllable shut-off valve ( ). At least one measuring and control device ( ) is connected to the gas volume flow sensors ( ), it receives their measured signals and sends control signals to the gas delivery element ( ) and to the controllable shut-off valve ( ).
