Ranger Irrigation Fluid Warming System
English
Introduction
The Ranger Irrigation Fluid Warming System is designed to warm irrigation fluids and deliver these at
flow rates under gravity up to 867 mL/min when the bag is hung 100 cm above the scope. At these flow
rates, the device maintains fluid output temperatures ranging from 33°C to 41°C (Note: This is for room
temperature fluids only). It takes less than 2 minutes to warm up to the 41°C set point temperature. The
alarm points on the Model 247 are 48°C and 50°C.
The fluid warming disposable set is sterile, latex-free, single-use-only and is designed to be used with the
reusable Model 247 warming unit.
Indications for Use
The Ranger Irrigation Fluid Warming System is intended to warm irrigation fluids.
Warnings and Cautions
warning
Electrical shock hazard. Do not open the warming unit case.
Do not substitute other devices (i.e. Model 245) for the Ranger Irrigation warming unit or Ranger
Irrigation disposable sets. Thermal or electrical injury or device damage may occur.
Do not continue use of the unit if the over-temperature alarm continues to sound and the temperature
does not return to the set point temperature. Immediately stop fluid flow and discard the disposable
set. Have the warming unit tested by a biomedical technician or call Arizant Healthcare Inc. Technical
Service.
Equipment not suitable for use in the presence of a flammable anaesthetic mixture with air or with
oxygen or nitrous oxide.
caution
Not for I.V. use.
Do not immerse the warming unit. Wipe with a clean, slightly damp cloth.
To prevent tipping, clamp the Ranger Irrigation warming unit to an I.V. pole with a minimum 14"
(35.6 cm) radius wheelbase and at a height no higher than 44" (112 cm). Failure to do so may result in
damage to the product.
