Principle of Operation
®
HOTLINE Warmer delivers blood and intravenous fluid at
normothermic temperatures under routine, gravity flow rates. All other
fluid warming systems suffer from cool-down between the warmer and the
patient connection. HOTLINE
providing active warming of the patient line all the way to the patient
connection.
Active warming is achieved by surrounding the sterile intravenous line
with a layer of precisely controlled warm recirculating solution ( a ), thereby
protecting the patient line against exposure to cold and eliminating patient
line cool-down.
The unique design of the HOTLINE
intravenous fluid to be delivered to the patient at normothermic
temperature at gravity flow rates to 50-5,000 ml/hr.

Infusate Delivery Temperatures

The following table shows the typical infusate delivery temperatures
at the patient end of an L-70 HOTLINE
Note: The setpoint temperature of the recirculating solution is
41.9°C.
