ABSTRACT:
A device or apparatus to insulate intravenous administration tubing is disclosed. The insulation device consists 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 actual tubing in which warm fluid flows. Three key functions are achieved with this device. One key function of the insulation device is to maintain the inner channel centered within the outer channel; this provides for maximum insulation efficiency/properties with the minimum of separating space. Another equally key function is to provide for transparency; the more transparent the insulation device the better the ability of the user to see the quality of the warm fluid flowing within, i.e. detect air bubbles. Another key function is to provide for ease of set-up and reusability. All components are to be made of clear, flexible, light-weight materials to permit insulation and visualization of I.V. fluids and air bubbles. The insulation device has particular use, but not limited to, in preventing convective heat loss of warmed I.V. fluid as it flows through the inserted patient I.V. tubing, that would otherwise be exposed to ambient room temperature.
