摘要： A gas regulating device for use in calibration of a gas analyzer has an inlet and an outlet, a valve arrangement comprising at least one valve, and valve regulator for regulating the at least one valve. The gas regulating device is intended to be connected between a calibration gas supply and a gas analyzer that is to be calibrated and the valve regulator is configured to regulate the at least one valve such that gas is allowed to flow through a gas flow path between the inlet and outlet only when a gas pressure in the gas flow path, between the at least one valve and the outlet, falls below a predetermined threshold value. The gas regulating device is used when calibrating side-stream gas analyzers in which case it reduces calibration gas consumption, prevents discharge of calibration gas into the ambient environment and prevents leakages jeopardizing correct calibration.

摘要： An anaesthetic machine for connection to a patient's airways has a fan with an inlet and an outlet, a first system of flow paths connected between the fan's outlet and inlet, and a second system of flow paths connected between the fan's outlet and inlet. A fast system with wide variability with respect to operating modes is achieved by arranging a shunt valve at the fan's outlet in order to regulate the amount of gas flowing into the first system of flow paths and the second system of flow paths respectively, and a control unit is provided to control the shunt valve.

摘要： An anesthetic apparatus has a control unit and a breathing circuit with a connector for fresh gas, a bellows system and an outlet valve. The anesthetic apparatus operates at least as an open system, the connector then constituting an inspiratory part of the breathing circuit and the bellows system and outlet valve constituting an expiratory part of the breathing circuit. In order to reduce the adverse impact of compressible volume in the expiratory section on the functioning of the anesthetic apparatus, the control unit regulates the bellows system during inspiration so that a counter pressure, largely corresponding to the pressure of fresh gas at the connector, is maintained in the expiratory section of the breathing circuit.

摘要： The present invention relates to a gas regulating device (2A-E) for use in calibration of a gas analyzer (4). The gas regulating device comprises an inlet (8A) and an outlet (8B), a valve arrangement comprising at least one valve (11; 11A, 11B), and valve regulating means for regulating the at least one valve. The gas regulating device is intended to be connected between a calibration gas supply (3) and a gas analyzer (4) that is to be calibrated and the valve regulating means is configured to regulate the at least one valve such that gas is allowed to flow through a gas flow path (5B) between the inlet and outlet only when a gas pressure (P1) in the gas flow path, between the at least one valve and the outlet, falls below a predetermined threshold value. The gas regulating device is advantageously used when calibrating side-stream gas analyzers in which case it reduces calibration gas consumption, prevents discharge of calibration gas into the ambient environment and prevents leakages jeopardizing correct calibration.

摘要： A breathing apparatus has a first delivery device for adding a volume of a substance to a gas flow, the delivery device having a gas inlet and a gas outlet. A unit monitors a presence of the substance in a gas downstream the delivery device using a first sensor unit at the gas outlet that provides a first measurement value based on an acoustic property of a gas in a first conduit. A second sensor unit at the gas inlet provides a second measurement value based on an acoustic property of a gas present in the second conduit. A control unit determines the presence of the substance based on the first measurement value or based on a comparison of the first measurement value and the second measurement value.

摘要： A device for the dosing of a dry additive gas into a breathing gas in a ventilator system, the ventilator system including a tubing system connectable by at a distal end to a patient, and has a dosing tube connectable to the tubing system for dosing to the distal end of the tubing system. The dosing tube is composed of a tube section having a moisture permeable contact surface, adapted to interact with moisture from exhaled breathing gas, so the dry additive gas is humidified before dosing to the distal end of the tubing system.
