    摘要： A system for controlled delivery of medicinal fluid includes a fluid pathway assembly defining a fluid pathway and including means for calculating a first calculated fluid flow rate using gas laws. The fluid pathway assembly has an inline flow sensor element received within the fluid pathway movable in response to fluid flowing in the fluid pathway. A flow control device is removably attached to the fluid pathway assembly and has a sensor for sensing a position of the inline flow sensor element in the fluid pathway, the position of the inline flow sensor element being representative of a second calculated fluid flow rate. The fluid pathway assembly includes a variable flow resistor adjustable to regulate a rate of fluid flow in the fluid pathway assembly. A drive mechanism attached to the flow control device is operably coupled to the variable flow resistor when the flow control device is attached to the fluid pathway assembly. The variable flow resistor is adjustable by the drive mechanism to achieve a target flow rate when the first calculated flow rate and/or the second calculated flow rate differs from the target flow rate.

    摘要： A portable infusion apparatus and method are provided for controlling the delivery of medicinal fluid to a patient. A fluid delivery system receives control input to control a setting of a variable fluid flow resistor. The variable fluid flow resistor resists passage of fluid through a fluid pathway between a fluid source and a recipient. The fluid delivery system; produces a control signal indicative of the setting of the variable fluid flow resistor; derives a fluid flow rate value from the control signal; and applies pressure to the fluid source to deliver the fluid from the fluid source to the recipient through the variable fluid flow resistor at a rate as specified by the derived fluid flow rate value.

    摘要： In one aspect, an extended range fluid flow resistor includes a housing having an inlet and an outlet and defining a fluid passageway therebetween A plunger is slidably received within the fluid passageway and an actuator is rotatably coupled to the housing and the plunger, such that rotation of the actuator causes sliding movement of the plunger within the fluid passageway The plunger has a sealing region and a variable flow region axially adjacent the sealing region Fluid flow through the fluid passageway is prevented when the sealing region is aligned with the inlet and fluid flow through the fluid passageway is permitted when the variable flow region is aligned with the inlet The variable flow region includes a helical groove extending from a first end of the variable flow region adjacent the sealing region and away from the sealing region to a second end of the vanable flow region.

    摘要： Methods and apparatus for air content and pressure measurement of sample fluid, especially sample fluid in association with an infusion pump. Volume change in a chamber as the chamber transitions between negative and positive pressure relates to the air content in the chamber. In particular, in an infusion pump, the volume change of infusion fluid as it transitions between being under negative pressure and positive pressure within a cassette central chamber, e.g., pumping chamber, relates to the air content in the infusion fluid. The outlet pressure of the cassette central chamber, e.g., blood pressure, can be monitored based on the cassette central chamber pressure.

    摘要： A fluid flow control system using flow rates to extract additional information from an in-line flow sensor. The system provides the ability to determine a position of a movable flow sensor element of a flow sensor by illuminating a photosensitive pixel array with a light source to create a first set of pixel intensity values introducing an abrupt change to the fluid driving pressure, illuminating the photosensitive pixel array with a light source to create a second set of pixel intensity values, and calculating the difference between the first and second sets of pixel intensity values as a function of pixel position.
