摘要： A flow sensor is disclosed that measures a flow of fluid passing through a conduit and a flow resistive element for use in such a flow sensor. The flow sensor includes a housing having a main channel defined therethrough. A flow resistive element is disposed in the housing across the main channel. The flow resistive element includes a rigid body member having a first surface and a second surface. A plurality of unobstructed, wedge-shaped, openings are defined in the body member and extend through the rigid body member. In addition, a plurality of spokes extend from a central portion of the body member to its perimeter so that each spoke separates adjacent wedge-shaped openings from one another.

摘要： A high frequency pressure oscillation device that selective restricts the flow of breathing gas to or from a patient to produce pressure spikes in the patient's airway that facilitate clearing secretions from the patient's airway. The device includes a patient circuit that defines a closed path between a source of breathing gas and the patient's airway. A valve is disposed in the patient circuit such that in an open position the path between the source of breathing gas and the airway of the patient is substantially unobstructed. When the valve is in a closed position, the path between the source of breathing gas and the patient's airway is at least partially obstructed to create the pressure spikes. An actuating system associated with the valve alternatively places the valve in the open position and in the closed position at a predetermined oscillation rate that is independent of patient effort.
摘要翻译： 一种高频压力振荡装置，其选择性地限制呼吸气体到达或来自患者的气体，以在患者的气道中产生压力尖峰，以便于从患者的气道清除分泌物。 该装置包括限定呼吸气体源与患者气道之间的封闭路径的患者回路。 阀门设置在患者回路中，使得在打开位置，呼吸气体源和患者的气道之间的路径基本上不受阻碍。 当阀处于关闭位置时，呼吸气体源与患者气道之间的路径至少部分阻塞以产生压力峰值。 与阀相关联的致动系统可替代地将阀置于打开位置并且处于关闭位置以与患者努力无关的预定振荡速率。

摘要： A fluid mixing apparatus and method in a fluid supply system that mixes a secondary fluid flow with a primary fluid flow in such a manner so as to minimize disruption of the fluid flow profile for the primary fluid flow downstream of the mixing point as the secondary fluid flow is introduced to the primary fluid flow. This is accomplished by providing a second conduit carrying the secondary fluid flow that is coupled to a first side of a first conduit carrying the primary fluid flow such that the secondary fluid flow travels around at least a portion of the first conduit. An inlet port arrangement is defined in the first conduit and is arranged such that a size of the inlet port arrangement that introduces the secondary gas flow from the second conduit into the first conduit increases as a distance around the first conduit from the first side increases.

摘要： A gas delivery system including a pressure generator, a pressure sensor, a control valve, and a processor. The pressure generator pressurizes breathable gas for delivery to a patient. The pressure sensor measures a pressure difference between the pressurized breathable gas and atmospheric pressure. The control valve is disposed downstream from the pressure generator and is constructed and arranged to control a flow rate of the pressurized breathable gas. The processor controls the control valve to bring the flow rate of the pressurized breathable gas to substantially zero while the pressure generator is operating and, when the flow rate is substantially zero, determines at least one of atmospheric pressure, an atmospheric air density, or a density correction factor based at least in part on the pressure difference between the pressurized breathable gas and the atmospheric pressure.

摘要： An RFID reader is configured to be worn on the arm of a user and includes a housing with a bottom surface for facing the arm of a user and a top surface facing away from the arm. A securement structure engages the arm of the user to secure the housing. An antenna is mounted within the housing and is angled with respect to the bottom surface of the housing for providing an RF field at an angle to the arm of a user to direct the RF field toward an item held by the arm. The antenna includes an indexing structure with multiple angular positions for orientation of the antenna. A key structure is positioned in the housing and configured for engaging the indexing structure at an angular position around the antenna to orient the antenna at a desired rotational orientation in the housing to tune the antenna. Grip structures are formed along the top surface of the housing for gripping an item held by a user that contains an RFID tag that is read by the RFID reader.
