Abstract: An intravenous infusion system that shows infusion flow rate, volume of medication infused, and alarming during malfunction. User intervention to adjust flow rates deviation is possible, using the data already stored in the system prior to the onset of making the adjustment. The system detects flow rate by measuring temperature dynamics in a section of the fluid path, unlike other systems that measures the electromechanical output of the pumping source if the counting of drops is not possible. This fundamental difference allows the invention to be used in any system that has a pumping source that provides a continuous fluid path as it measures actual flow of fluid in a segment of the fluid path, independent of pumping mechanism design.

Abstract: A pump apparatus that exerts a constant force on a bag of fluid to provide a uniform flow rate compared to elastomeric pumps. The apparatus comprises a first and a second block member positioned over a plate, which are moveable to define an opening to receive a wedge member attached on the plate. The block members are coupled by a resilient means that is extendable when the wedge member is urged into the opening. The extended resilient means is retractable such that the plate exerts a constant force on the bag to expel fluid in a uniform flow rate.

Abstract: A pump apparatus that exerts a constant force on a bag of fluid to provide a uniform flow rate compared to elastomeric pumps. The apparatus comprises a first (101) and a second block member (102) positioned over a plate (125), which are moveable to define an opening to receive a wedge member (161) attached on the plate. The block members are coupled by a resilient means (140) that is extendable when the wedge member is urged into the opening. The extended resilient means is retractable such that the plate exerts a constant force on the bag to expel fluid in a uniform flow rate.

Abstract: A method of combining a drug in a first container and a liquid in a second container includes placing the first container and the second container in fluid communication with a housing, combining the liquid and the drug in the first container, transferring the liquid and the drug from the first container to the housing, and transferring the liquid and the drug from the housing to a third container.

Abstract: An apparatus for selecting a flow rate of a fluid includes a barrel including an output port and a plurality of input ports; and an axle disposed substantially concentrically within the barrel. A plurality of drain channels are formed in an outer surface of the axle, each drain channel having a depth less than a thickness of a wall of the axle. The axle is rotatable within the barrel to provide one of a plurality of flow paths between one of the plurality of input ports and the output port, each flow path at least partially defined by at least one of the drain channels.

Abstract: A pump for the delivery of a fluid includes a core, a restrictor, and an expandable bladder. The core is configured to extend longitudinally along an axis of the pump. The restrictor is configured to limit the longitudinal extension of the core to a predetermined maximum length. The expandable bladder is attached to the support core in at least one position and configured to receive a fluid.

Abstract: An apparatus for selecting a flow rate of a fluid includes an axle including an elongated cylindrical member having flow paths, each flow path being defined by a corresponding set of radial holes, each set of radial holes comprising at least one radial hole that extends substantially between an outer surface of the axle and an interior cavity of the axle, and a barrel including an elongated cylindrical member within which the axle is disposed, the barrel having input ports and an output port, the barrel being configured to enable the axle to rotate about an axis of rotation that extends along a length of the axle, wherein a flow rate of a fluid is selected by rotating the axle to a position so that a set of radial holes is in alignment with one or more ports of the barrel.

Abstract: A medical fluid control device includes an actuator that is selectively operable to cause fluid to be delivered from a fluid source to a patient at a basal rate of flow via a first flow path, or cause a bolus dose of fluid to be delivered from a bolus reservoir to the patient via a second flow path.
