摘要： A ventilator or fluid delivery system that provides a flow of gas to an airway of a user. The ventilator includes a source of gas (30, 32), a conduit (63, 65, 42) that carries the flow of gas to the airway of a patient, a first valve (38, 40) that controls a pressure, flow, or volume, of the flow of gas, a pressure sensor (46) operatively coupled to the conduit between the valve and the patient and adapted to monitor a pressure of the gas in the conduit, and a controller (50) adapted to control the valve based on an output of the pressure sensor. The ventilator further includes a restrictor (62) provided in the conduit between the pressure sensor and the patient. The restrictor, in essence, divides the fluid delivery system such that a first volume is defined in the conduit between the valve and the restrictor and a second volume is defined in the conduit between the patient and the restrictor, wherein the first volume is less than the second volume. The control system controls the pressure, flow, or volume relative to the first volume so that an accurate, fast, and stable control of the pressure, flow, or volume is achieved.

摘要： A ventilator includes a sensor to monitor a characteristic associated with the delivery of gas to the patient, such as pressure. A sensor power supply (100, 130) is feeding a sensor in the form of a Wheatstone bridge. A first end (104) of the bridge is coupled to a first positive voltage source (112, 142) and a second end (116) is coupled to a second positive voltage source (118, 156, 180). A capacitor (120) is coupled to the second end of the bridge. A controller (50) controls the first and the second positive voltage sources so as to (a) disable the sensor by causing the first positive voltage source to provide substantially zero voltage to the first end of the Wheatstone bridge and by causing the second positive voltage source to provide a positive voltage to the second end of the capacitor, and to (b) enable the sensor by causing the first positive voltage source to provide a positive voltage to the first end of the Wheatstone bridge and by causing the second positive voltage source to provide a decreasing voltage to the second end of the capacitor.

摘要： A method is described for measuring a flow of gas passing a flow meter device. The device causes a pressure drop when a gas flows through it. The pressure drop across the device is a measure of the gas flow. The device is designed as a gas permeable tube (81) which has a flow channel on the upstream side along the tube designed so as to decrease the cross-section of the channel downstream of the gas permeable tube. This provides for a minimum volume in the channel upstream of the device's pressure-drop- generating component. By combining a gas permeable element with a flow meter element having a variable restriction, an advantageous flow meter with fast response times, and a high dynamic flow range is provided.
