Abstract
A unitary molded elastomer conduit for use with a medical infusion pump. The molded conduit includes a plurality of elongated tubular sections defining a continuous lumen therethrough. A first interior surface of the molded conduit includes an interior region having surface characteristics for clamping off the lumen to stop the flow of fluid transport, or for clamping the lumen for use with the peristaltic mechanism of the medical infusion pump. Another interior surface is provided in the molded conduit which is associated with another of the plurality of elongated sections of the integral elastomer conduit. The second interior surface defines a second interior region having surface characteristics for coupling ultrasound across the conduit traversed to the lumen in order to detect gas entrainment and the like. The second interior region thus provides a textured surface relative to the first interior region to direct the signal energy from the signal coupled across the conduit traversed to the lumen. Additionally, external features may be provided for positioning the plurality of elongated tubular sections of the conduit relative to the peristaltic pumping mechanism of the medical …
