摘要： A system that provides a flow of gas to an airway of a user that includes a source of gas, a conduit that carries the flow of gas to the airway of a patient, a first valve that controls a pressure, flow, or volume, of the flow of gas, a pressure sensor coupled to the conduit between the valve and the patient that monitors a pressure of the gas in the conduit, and a controller that controls the valve based on an output of the pressure sensor. A restrictor is provided in the conduit between the pressure sensor and the patient that divides the fluid delivery system with a first smaller volume in the conduit between the valve and the restrictor and a second larger volume between the patient and the restrictor. The system controls the pressure, flow, or volume relative to the first volume.

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： The invention pertains to a ventilator that delivers a flow of gas to an airway of a user, and to communicate a flow of gas from the airway of the user in a controlled manner. The ventilator includes a conduit (1, 3) that carries a flow of gas from the airway of a patient, a first valve (7) coupled to the conduit and adapted to control a pressure or rate of the flow of gas exhausted from the conduit, a first sensor (10) coupled to the conduit and adapted to monitor a pressure of the gas in the conduit, and a controller (12) adapted to control the first valve based on an output of the first sensor. A restrictor (8) is provided in the conduit between the pressure sensor and the patient such that a first volume is defined in the conduit between the first valve and the restrictor and a second volume is defined in the conduit between the patient and the restrictor. The controller controls actuation of the first valve based on a pressure of the first volume monitored by the first sensor.
