Abstract: A synthetic insulation material that rivals and surpasses down in performance without suffering degradation in insulating power over time. The material is an aggregate of particulate units that have a fractal-like geometric configuration. The geometric configuration includes non-integer dimensionality that promotes physical entanglements of the particulate units. The physical entanglements impart a high frictional resistance to slippage of the particulate units to maintain loft over time by inhibiting the settling of particulate units upon compression. The geometric configuration further includes aspects of self-similarity. The particulate units are formed from a material that efficiently scatters thermal radiation.

Abstract: A system for eliminating or reducing static electricity in infusion pumping systems which may cause artifacts in electrocardiograms is disclosed. Infusion pumping systems deliver prescribed infusates to a patient. Frequently, such infusion systems are used in conjunction with electrocardiogram monitors. Static electricity generated at or by the infusion pumping system may cause artifacts in the electrocardiogram monitor. The present invention reduces or eliminates this static electricity by forming parts in relative motion of a similar material to reduce generation of static electric charges. The pumping piston and diaphragm wall of a pumping chamber may be formed from a similar material. The valve pistons and valve diaphragms may be formed of a similar material. The removable pumping cassette and cassette receiver may be formed from a similar material. The present invention also reduces the formation of static electric charges by coating the cassette with an antistatic material.
