Abstract:
An LVP that provides peristaltic pumping to removably couplable administration set tubing assemblies supplying medical infusate. The LVP includes a housing, a drive-train assembly, and a controller. The housing includes an assembly receptacle configured to receive an administration set tubing assembly. The drive-train assembly provides mechanical peristaltic movement within the assembly receptacle. The drive-train assembly includes a stepper motor located within the housing and a camshaft assembly, driven by the stepper motor and at least partially extending into the assembly receptacle. The camshaft assembly includes a unitary camshaft and a plurality of tube engaging members that cooperatively move according to rotation of the unitary camshaft. Further, the controller is located within the housing that controls operation of the stepper motor and the camshaft assembly.

Abstract:
Embodiments include a system providing group coordination of operational features of a plurality of medical devices. The system includes a plurality of medical devices each including a control engine having a set of device-specific parameters governing operation of an operational feature. The system also includes a rack providing a mounting structure for coupling the plurality of medical devices by releasable engagement. The system further includes a communication architecture in the rack providing connectivity between the plurality of medical devices when the plurality of medical devices are coupled to the rack. The control engines in the plurality of medical devices are interoperable with respect to the operational feature and automatically modify the set of device-specific parameters in each one of the plurality of medical devices when coupled to the rack for group coordination of the operational feature.
Abstract:
Infusion pump interfaces providing simple and intuitive user experiences. A controller display subsystem for implementing infusion pump interfaces includes a processor, a memory, display logic, keypad I/O, and screen I/O. Display logic can command the processor via the memory to implement desirable displays on screen I/O.
Abstract:
Embodiments include a system of localized cloning of a plurality of child medical devices with common operating parameters of a parent medical device. The system includes a rack including a plurality of mounting structures configured to physically and removably couple a plurality of child medical devices and a parent medical device. The system also includes a digital communication bus provided on the rack that enables communication between the parent medical device and the plurality of child medical devices that are coupled to the rack. Additionally, the parent medical device adjusts one or more operating parameters of the plurality of child medical devices with communications sent via the digital communication bus.
Abstract:
An assembly is configured to position a peristaltic tube with respect to a linear peristaltic pump drive of an infusion pump. The assembly can include a peristaltic tube, first and second tube couplers, a frame, first and second securement plates, a free-flow prevention arm, and a biasing mechanism. The frame can include a snap-fit tab configured to releasably secure the assembly to an assembly receptacle of the infusion pump. The free-flow prevention arm can be selectively movable between a free-flow preventing position and a free-flow allowing position. A latching mechanism can be ergonomically manipulable to latch the free-flow prevention arm in a free-flow allowing position, and to unlatch the free-flow prevention arm such that the biasing mechanism is able to bias the free-flow prevention arm to the free-flow preventing position.

Abstract:
An infusion pump is configured to deliver fluid in an infusion line. The infusion pump can include a first air-in-line detector (AILD) configured to provide signals indicating air present or air not present in the infusion line at a first location, a second AILD configured to provide signals indicating air present or air not present in the infusion line at a second location downstream from the first location, and a controller configured to receive signals from the first AILD and the second AILD. The controller can be programmed and configured to perform lowest-volume calculations of air in the infusion line based upon the signals from both the first AILD and the second AILD, and to annunciate air-in-line alarms based upon the lowest-volume calculations.
