  • Patent number: 6830794
    Abstract: Insulated intravenous administration tubing is disclosed. One embodiment of the present invention includes a single medical solution or I.V. tubing manufactured of a polymeric material having good flexibility and comprising an insulation polymer or having an insulation medium applied to the inner or outer surface of the tube or blended into the tube during or after forming, with Mylar being an advantageous insulation material. The present invention may also consist of a long tubular-like structure which consists of two concentric channels, an inner channel and an outer channel. The inner channel accepts and encloses the tubing in which warm fluid flows. Three key functions are, achieved: the inner channel is centered within the outer channel; this provides for maximum insulation efficiency/properties with the minimum of separating space, transparency may be provided; i.e. the more transparent the insulation the better the ability of the user to see the quality of the warm fluid flowing within, i.e.

  • Publication number: 20040059295
    Abstract: A rapid infusion system for the intravenous delivery of fluids at standard and rapid flow rates. The system includes a pump assembly, a drive assembly to power the pump, and a fluid containment system that keeps the infused fluid out of direct contact with the pump assembly and that is preferably disposable and removable. In one embodiment the drive assembly includes a differential drive that interacts with more than one motor. In one embodiment, the pump assembly includes a roller pump and the pump chamber is a collapsible, preformed tube that is preferably attached to a pump cartridge frame. Optionally, the system includes a self-leveling drip chamber and the fluid containment system is disposable and includes a pump cartridge containing the drip chamber and the pump chamber, I.V. tubing, outlet infusion tubing, and a heater cartridge.
