An anesthetic breathing apparatus has a processing unit, a breathing circuit for providing an inspiratory patient gas mixture of re-breathed gas and/or fresh gas to a patient fluidly connected to the breathing circuit, and a fresh gas supply controllable by the processing unit for supplying a flow of the fresh gas to the breathing circuit in a composition including oxygen and at least one anesthetic agent (AA). A user interface includes a first user input element for receiving operator input for an anesthetic target value including an end expiratory concentration of the AA (EtAA) target value and/or an end expiratory minimum alveolar concentration (EtMAC) target value of an end expiratory MAC value of the patient, and a second user input element for receiving operator input for a desired control profile for the fresh gas supply for obtaining at least the anesthetic target value. The inspiratory patient gas mixture is controlled based on at least the anesthetic target value, the oxygen target value, and the desired control profile.

In a breathing apparatus and a method for the operation thereof, a gas monitor monitors at least one gas and includes a pump that controls a sidestream flow from a patient circuit to the gas monitor via a sampling line having a first end connectable to the gas monitor and a second end connectable to the patient circuit. At least one pressure sensor measures a pressure at the sidestream gas monitor and provides a first pressure signal indicative of the measured pressure. A processor determines if a leakage is occurring in the sampling line based on the pressure signal.

A ventilator for respiratory care, intended for connection to a patient, avoids needless alarms, caused by a patient's attempts to speak and needless suffering because of the patient's inability to trigger an alarm, by having a sound detector arranged to detect and identify sounds made by the patient, preferably intentionally. A control unit is operatively connected to the sound detector acts on at least one function in the ventilator on the basis of sounds identified by the sound detector.

An anaesthetic vaporizer for dosing a liquid anaesthetic has a liquid container for the anaesthetic, and outlet tube from the liquid container to a dosing point, a first regulator for regulating a flow of anaesthetic from the liquid container toward the dosing point and a control unit for controlling dosing. To improve dosing and safety, the anaesthetic vaporizer has a return tube connected in parallel across the first regulator by a first connection point, downstream from the first regulator, and a second connection point, upstream from the first regulator, a second regulator is arranged in the return tube and a third regulator is arranged in the outlet tube, downstream from the first connection point. The control unit controls at least one of the regulators in dosing the anaesthetic.

A device for use in an anaesthetic administration apparatus for identifying at least one liquid anaesthetic in the anaesthetic apparatus has a measuring unit for determining at least one parameter related to the refractive index of the liquid anaesthetic, a unit for determining the temperature of the liquid anaesthetic and an analysis unit for identifying the anaesthetic from the determined parameter.

Device for identifying liquid anaesthetics

A dispenser unit for a non-gaseous flowable material has a holder for the flowable material with an aperture therein through which the material can be transferred between into and out of the holder, and a flow meter for measuring flow of the material during transfer. The flow meter has a sensor, for example a differential pressure meter which determines a pressure difference between two locations which are vertically spaced from each other within the holder, one above and one below the surface of the material, at a number of times during the transfer. The meter emits a signal indicative of the flow from a calculation of the rate of change of the determined pressure difference.
