    摘要: In a method and apparatus for determining an aspiration flow and an aspiration time during aspiration of a dead space, the aspiration is made more effective by determining the volume of the dead space to be aspired during an expiration, determining an expiration flow with respect to time during at least a latter part of the expiration, and optimizing the aspiration time and the aspiration flow from the determined volume of the dead space and the measured expiration flow with respect to time is such a way that the dead space can be aspirated during an ongoing expiration with a minimum of interference to the flow balance in the expiration flow as observed from a point upstream and/or downstream the dead space.

    摘要: A patient ventilation system has a flow regulating and gas mixing arrangement connected to an inspiratory channel of the system from which a gas mixture containing oxygen and at least a second gas is delivered to the system's proximal tubing. The proximal tubing further is connected to an expiratory channel and is connectable to a patient. The system further has at least two gas inlets connected to the flow regulating and mixing arrangement, and a gas identification unit in which the at least second gas supplied to the system via one of the gas inlets can be identified. By actively measuring a value that is dependent on the characteristics of the delivered gas, and by correcting the calibration of the flow regulating and gas mixing arrangement and/or the flow meter(s) based on this value, both safety and flow regulation in the system are enhanced.

    摘要: A mechanical breathing aid has first and second inlets respectively connectable to a source of air and a source of oxygen. A mixing location is in gaseous communication with the first and second inlets, at which controlled amounts of air and oxygen from the respective inlets are mixed. An acoustic analyzer operates during a measurement procedure to access a moisture content value for air from the source of air, to generate acoustic velocity-related information from acoustic energy interaction with the breathing gas, and to determine therefrom an oxygen content. The analyzer operates during a calibration procedure to generate acoustic velocity-related information from acoustic energy interaction with air from the source of air, and to determine therefrom an oxygen content value for the air from which is determined a moisture content value for air.

    摘要: A device is directly or indirectly connectable to a patient for determining a volume related to the lungs of the patient. The device has an inspiration part through which a breathing gas passes towards the patient, and an expiration part through which the breathing gas passes away from the patient. The inspiration part has a mouthpiece for introducing a change of the gas composition in the breathing gas. The device implements a method for determining the volume with a detector being arranged in the expiration part that measures a measuring parameter which is dependent on the change in the gas composition, and with a calculation unit connected to the detector unit that determines the variation in the measuring parameter, and determines the volume from the determined variation.

    摘要: In a calibration apparatus and method for a resistance thermometer a reference thermometer is located in thermal contact with a gas composition to generate, during a calibration period, a first reference temperature value for the gas composition at a first temperature, and an acoustic meter is located in acoustic contact with the gas composition and, during the calibration period, makes an acoustic velocity-related measurement for use in generating a second reference temperature value for the gas composition at a second temperature. A calibration unit coordinates the first and second reference temperature values with first and second measurement temperature values provided by the resistance thermometer at the first and the second temperatures, respectively, and establishes a calibration relationship therefrom.

    摘要: A valve assembly has a valve opening which can be sealed and un-sealed by movement of a membrane 6, a force generator, such as an electromagnetic force generator having a solenoid and armature arrangement, and a shaft that is operably connected to the membrane and which is movable along a movement axis under the influence of the generated force to move the membrane and thereby regulate the degree of opening of the valve. Bearing assemblies are provided to procure a magnetic suspension of the shaft, permit its movement along the axis, and also to optionally produce a magnetic biasing of the shaft in a direction along the axis, particularly in the absence of a generated force.

    摘要: In an anesthesia vaporizer for vaporizing an anesthetic agent liquid and a method of vaporizing an anesthetic agent liquid in an vaporizer, an evaporation unit evaporates the anesthetic agent, a delivery unit intermittently adds a volume of said liquid to the evaporation unit in order to evaporate at least a portion of the volume of the liquid from the evaporation unit. A heat energy storage unit includes a phase change material (PCM) and is thermally coupled to at least a portion of the evaporation unit. The PCM has a phase shift temperature that is higher than the evaporation temperature of the anesthetic agent. The PCM in the heat energy storage unit is preferably at least partly liquid at an operative temperature of the vaporizer.

    摘要: A nerve stimulation device has a pulse generator for generating stimulation pulses and an output for the stimulation pulses from the pulse generator, which is connectable to an electrode arrangement adapted for interaction with a living being to stimulate the phrenic nerve. The nerve stimulation device is made more safe and effective by the provision of an input connectable to an esophageal electrode for the reception of measurement signals. The esophageal electrode is adapted to be inserted in the esophagus of the living being for obtaining measurement signals. A signal analyzer filters myo-electrical signals from the diaphragm out of the measurement signals and a regulating unit regulates the pulse generator dependent on the myo-electrical signals.
