Introduction; Model 245 Blood/Fluid Warming System; Model 247 Irrigation Warming System; Indications For Use - Ranger 245 Service Manual

Introduction

The Ranger warming system includes a warming unit and a disposable administration set. The Ranger
warming unit is designed to be mounted to an I.V. pole. A handle located on the top of the unit makes
transport easy. When mounted to the I.V. pole, the unit fits easily above the Bair Hugger® 500 or 700 series
warming unit.

Model 245 Blood/Fluid Warming System

The Ranger Blood/Fluid Warming System is designed to warm blood, blood products, and liquids and
deliver these at flow rates from KVO to 500 mL/min. 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 245
are 43°C and 44°C.
Disposable blood/fluid sets are available for stand flow, high flow, and pediatric applications. Disposable
sets are sterile, latex-free, single-use-only items and are designed to be used with the reusable warming unit.
Do not use other disposables with the Model 245, including those designed for the Model 247 Irrigation
warming system.

Model 247 Irrigation Warming System

The Ranger Irrigation Warming System is designed to warm irrigation fluids and deliver these at flow rates
from 0 to 867 mL/min. 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 Ranger Irrigation Fluid warming disposable set is sterile, latex-free, single-use-only and is designed to
be used with the reusable Ranger Irrigation warming unit. Do not use other disposables with the Model
247, including those designed for the Model 245 Blood/Fluid warming system.

Warnings and Precautions

danger
Explosion hazard. Do not use in the presence of flammable anesthetics.
warning
• Electrical shock hazard. Do not open the warming unit case.
• Do not substitute other devices for the Ranger warming unit or Ranger disposable sets. Thermal or
electrical injury or device damage may occur.
• Never infuse fluids if air bubbles are present in the fluid line, as air embolism may result (Model 245 only).
• 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.
