Unitary molded elastomer conduit for use with a medical infusion pump

A method of making a unitary molded elastomer conduit for use with a medical infusion pump, the conduit comprising:

• providing a plurality of elongated tubular sections defining a continuous lumen therethrough;
• molding a first interior surface of the conduit associated with one of the plurality of elongated tubular sections comprising a first interior region for clamping off said lumen;
• molding a second interior surface of the conduit associated with another of the plurality of elongated tubular sections comprising a second interior region for coupling a signal across the conduit transverse to the lumen to characterize the fluid transport, said second interior region having a textured surface relative to said first interior region directing the signal energy from the signal coupled across the conduit transverse to the lumen;
• and
• said first interior region and its associated elongated tubular section being positioned relative to the peristaltic pumping mechanism of the medical infusion pump.

A method of infusing a medicament with a medical infusion pump, the method comprising the steps of:

• molding a unitary elastomer conduit having a plurality of tubular sections defining a continuous lumen therethrough;
• securing the conduit in a cassette for being received by the medical infusion pump;
• providing a first interior surface of the conduit associated with one of the plurality of elongated tubular sections with a first interior region for clamping off the lumen;
• providing a second interior surface of the conduit associated with another of the plurality of elongated tubular sections with a second interior region for coupling a signal across the conduit traversed to the lumen to characterize fluid transport;
• texturing the surface relative to the first interior region to facilitate the transmission of the signal coupled across the conduit traversed to the lumen;
• and
• receiving a liquid medicament at the conduit, the first interior region and the associated tubular section being positioned relative to the peristaltic pumping mechanism of the medical infusion pump for fluid transport through the continuous lumen defined by the plurality of elongated tubular sections of the conduit.

A medical infusion pump comprising:

• a pump chamber cassette conduit comprising
• a plurality of elongated tubular sections defining a continuous lumen therethrough;
• a first interior surface of the conduit associated with one of the plurality of elongated tubular sections comprising a first interior region for clamping off said lumen;
• and
• a second interior surface of the conduit associated with another of the plurality of elongated tubular sections comprising a second interior region for coupling a signal across the conduit transverse to the lumen to characterize the fluid transport, said second interior region having a textured surface relative to said first interior region directing the signal energy from the signal coupled across the conduit transverse to the lumen;
• a tube for receiving a liquid medicament at the conduit, the first interior region and the associated tubular section being positioned relative to the peristaltic pumping mechanism of the medical infusion pump for fluid transport through the continuous lumen defined by the plurality of elongated tubular sections of the conduit;
• and
• a peristaltic pump mechanism for transporting the liquid medicament across the conduit of the pump chamber cassette.
