Abstract
Official abstract text for this publication.
A system and method determine when fluid is not flowing properly from a secondary infusion source during a secondary infusion. The system includes an upstream pressure sensor and a processor programmed to receive signals from the sensor and analyze the signals to determine if secondary fluid flow is proper. The processor samples the output signals from the upstream pressure sensor and analyzes the sampled signals to determine if a pressure rise in the infusion line has occurred when the secondary infusion is initiated. If a pressure rise, indicating that fluid from the secondary container has begun flowing into the infusion line, has not been detected, the processor is programmed to provide a signal indicating that attention should be given to the infusion set up.
First claim
Opening claim text (preview).
We claim: 1. A method for passively detecting a fault condition in an intravenous (IV) set having a primary line coupled to a first fluid source, a secondary line coupled from a second fluid source to a fitting, upstream of a pumping mechanism, on the primary line, a check valve in the portion of the primary line between the first fluid source and the fitting, a valve in the portion of the secondary line between the second fluid source and the fitting, and a portion of the primary…
