HOTLINE
®
Blood and Fluid Warmer | Operator’s Manual
SECTION 2
Description
The HOTLINE
Warmer delivers blood and intravenous fluid at
normothermic temperatures by surrounding the sterile intravenous line
with a layer of warmed recirculating solution. An onboard recirculating
solution supply is heated to 39.5°C ± 0.5 and circulated through the outer
lumen of the HOTLINE
Fluid Warming Set, which surrounds the
intravenous line.
The HOTLINE
Warmer employs a safe, recirculating solution heating
system, inherently free of “hot spots,” to actively warm the patient line.
Electronic circuitry continuously monitors the recirculating solution
temperature. The primary temperature control circuit limits the
recirculating solution to 40°C maximum. In the unlikely event of a
malfunction of this circuit, a second “watchdog” circuit will visually and
audibly alarm and stop the recirculating solution pump if the temperature
reaches 41.2°C. Fluid in the HOTLINE
Fluid Warming Set is never
exposed to any damaging or dangerous temperatures while the
HOTLINE
Warmer is operating.
The recirculating solution temperature and visual alarms are indicated on
the Display Panel on the front of the HOTLINE
Warmer. A green
Operating light illuminates on this panel when the HOTLINE
Warmer is
set up and operating correctly.
