摘要： In a method and an arrangement for acoustic determination of an instantaneous fluid temperature, acoustic velocity V in a fluid is monitored and an output signal related to the acoustic velocity is generated. A conventional temperature sensor senses a fluid temperature TS and generates an output signal related thereto. A signal processor receives the signals from the sensor and the acoustic velocity monitor determines the instantaneous fluid temperature TA based on a relationship: TA=kV2; where k is a constant dependent on the composition of the fluid that is calculated within the signal processor based on the relationship: k=TS/V2

摘要： In a method for detecting a variation, such as a variation in the concentration of a substance, in a flowing medium, a sample of the medium is made to flow past a sensor for detecting the variation, with the direction of flow of the sample being reversed and the velocity of the sample in relation to the sensor being reduced during passage of the sample through the sensor. A device for detecting such a variation contains a sensor and a pump controlled to reverse the direction of flow and to reduce the velocity of the sample of the medium for making a measurement of the sample.

摘要： In a valve having a mechanically journalled movable element for regulating the valve's degree of opening, and in a method for controlling such a valve, the movable element and journals are made to move in relation to each other in order to reduce friction in the journals of the movable element. The movable element is then in a position governed by the valve's prevailing degree of opening.

摘要： An anesthesia system has a fresh gas source for supplying a defined flow of fresh respiratory gas to a respiratory circuit wherein the flow is regulated by a flow valve which is controlled on the basis of a flow measured by a flow meter. The anesthesia system is permits the flow meter to be calibrated while the system is in operation to permit the supply of a continuous, or substantially continuous, flow of fresh respiratory gas to the respiratory circuit.

摘要： A device for flushing a deadspace during mechanical ventilation of a patient with a ventilator includes a reservoir having a variable volume container, such as a balloon, adapted to receive and hold a portion of the pressurized breathing gas provided by the ventilator during an inspiration phase and to supply, at least during a final part of an expiration phase, the received breathing gas as pressurized flushing gas to a first end of a conduit which is disposed in a patient's airway. The reservoir has an outlet in pressure communication with the first end of the conduit and operable to supply the flushing gas as a result of the pressure at the first end of the conduit falling below that of the gas within the reservoir.

摘要： A ventilator system has an inspiratory line, an inspiratory pressure meter arranged to sense pressure in the inspiratory line, and expiratory line, an expiratory pressure meter arranged to sense pressure in the expiratory line, and a connector device for connecting a patient to the ventilator system. The connector device includes a first gas line connected to the inspiratory line, and a second gas line connected to the expiratory line so that gas will only be able to flow in one direction through the lines. Pressure in the lungs can accordingly be directly measured by the expiratory pressure meter during inspiration and by the inspiratory pressure meter during expiration.
