Chapter 1: Functional Description

1.1 Introduction

The GE Healthcare Panda and Giraffe Warmers are devices with a radiant heating source intended to
maintain the thermal balance of an infant patient by direct radiation of energy in the infrared region of the
electromagnetic spectrum.

Radiant heat from an infrared heat source is focused onto the bed to warm the patient. The operator may
select either the heater power (manual mode) or skin temperature (baby mode) control method. Depending
on the control method selected, the heater is either regulated at the operator selected power level or the
heater output is modulated to maintain the patient’s temperature at the value selected by the operator.

The Panda and Giraffe Warmers are each offered in a bedded model: the Panda iRes Warmer and the
Giraffe Warmer. The Panda Warmer also offers two non-bedded models: Freestanding and Wall Mount. The
model type is indicated on the label and on the device’s splash screen.

Splash Screen

The information in this manual refers to all models, unless otherwise specified. The term “bedded” refers to
both the Giraffe Warmer and the Panda iRes Warmer.

The Giraffe model is intended for use in a neonatal intensive care unit. It features a mattress which can be
rotated as needed by the operator to gain better access to the patient. Also included are general
observation lights and a procedure light.

The procedure light is mounted on a ball joint so that it can be directed where needed on the bed surface.

The Panda models are intended for use in a labor and delivery unit. They also include the same general
observation lights as the Giraffe Warmer, but the procedure light is optional.

All Giraffe and Panda units feature the same heater head to house the radiant heater. Due to the small size
of the heater reflector and its compound elliptical shape, designed specifically for this product, the heater
head is very compact compared with other warmers currently on the market. This compact size limits the
area the heater head occupies over the bed surface. By leaving the area over the bed clear, the caregiver
can observe and treat the patient unobstructed. Additionally, this open area allows the head of an X-ray
machine to be placed over the patient without moving the heater head or patient.

All Giraffe and Panda units also feature optional integrated SpO

and Resuscitation Modules. The SpO2

2

option allows the caregiver to monitor the patient’s blood oxygen level, while the optional Resuscitation
Module allows the caregiver to administer forced breathing if required. The Resuscitation Module may
feature either a traditional bag and mask technology or a T-piece technology.

1-2 Service Manual

Chapter 1: Functional Description

Introduction

An additional feature, unique among warmers is the Hands Free Alarm Silence. This is a standard feature on
all Giraffe and Panda Warmers. Alarms may be silenced just as they would with the alarm silence button,
but without touching the unit. The proximity sensor for the Hands Free Alarm Silence is located in the alarm
light panel. The alarm can be silenced by gently waving one’s hand approximately two to six inches in front
of the sensor. Both units also have a conventional alarm silence button as an alternate way of silencing
alarms.

1.2.1 Heater Head Assembly

The heater head assembly contains general observation lighting, optional procedure lighting, radiant
heater, reflector, alarm light, alarm speaker, power inlet, accessory power outlets, communication port , user
input controls, graphics display, and electronic Control Boards. The heater head assembly contains the
main interfaces for the operator. The control touch panel controls the warmer, and statuses are monitored
on a color display. Radiant heat emanates from the reflector located in the heater head. All lighting and
their controls are located in the heater head.

1.2.2 Rails

The rails support the heater head, resuscitation (except for Wall Mount), and probe panel assembly.

1.2.3 Optional Resuscitation Assembly (Bedded and Freestanding Only)

The optional resuscitation assembly is located between the two rails and operates independently from the
rest of the product. The warmer may be configured with either a bag and mask resuscitation system or a
T-piece resuscitation system.

1.2.4 Probe Panel Assembly

The probe panel assembly is located between the two rails. It contains the standard connection for the
patient probe, which provides an input of the patient’s temperature to the warmer. It also contains a scale
connection so that a patient’s weight can be displayed and recorded by the warmer (when equipped with a
scale). In addition, there is an optional SpO

connection, for a SpO2 probe.

1.2.5 Base Assembly (Bedded and Freestanding Only)

Bedded model: The base assembly supports the rails and bed assembly. It contains supports for 4 locking
casters, so that the warmer can be moved to any location within a hospital. The mounting location for the
rails and bed assembly are separated from the caster supports by a column which adjusts in height. Two
column types are available. One column type can be adjusted manually, and the other can be adjusted
electrically by foot pedal controls on the caster supports.

Freestanding model: The base assembly supports the rails. It contains supports for 3 casters.

1-8 Service Manual

1.2.6 Bed Assembly (Bedded Only)

The bed assembly is mounted to the base assembly via a pivot and actuator. This assembly point allows the
bed to pivot relative to the base. The pivot is normally locked, but a release handle allows the operator to
unlock the pivot and adjust the angle of the bed. Once the desired angle is achieved, the handle is released,
and the pivot locks again. There are two versions of the bed assembly. The Giraffe Warmer uses a
65 × 48 × 4 cm mattress with rounded ends, which can be translated side-to-side, and rotated. The
Panda iRes Warmer uses a fixed rectangular mattress measuring 66 × 48 × 2 cm.

1.2.7 Optional In-Bed Scale (Bedded Only)

There is a scale option, located in the bed, which can weigh the patient. The scale uses the graphics display
on the warmer to display its measured weight.

1.2.8 Optional SpO2 Module

The SpO2 probe connects to the SpO2 module. The SpO2 module uses an OEM pulse oximetry board. The
warmer includes a small circuit to isolate the power and communicate with the OEM pulse oximetry board,

so as to pass its parameters to the display without modifying the parameters or alarms. The
communication is performed using a serial data bus. The modules are procured from Masimo or Nellcor.

Chapter 1: Functional Description

Mechanical Modules

1.2.9 Giraffe Shuttle Accessory (Bedded Only)

The Giraffe Warmer and Panda iRes Warmer can be used with the Giraffe Shuttle, a mobile power source
that allows for transport of the patient between care areas within the hospital building and provides power
to the warmer. These areas include, but are not limited to, Labor and Delivery, NICU, Radiology, and
Operating Room. The warmer with the Shuttle is not intended for use outside of the hospital building.

1.3.2 Hands Free Alarm Silence

FIGURE 1-5. Hands Free Alarm Silence

This processor-controlled circuitry resides on the Alarm Light Board. (Refer to Figure 1-5.) The user input is
accomplished with an infrared emitter/receiver pair. The emitter/receiver pair is monitored by the alarm
light microprocessor, which sends the alarm silence signal to the main application processor. The main
application processor uses this signal as one of two inputs to determine whether the alarm should be
silenced. The Hands Free Alarm Silence may be enabled/disabled/disengaged through Service Mode.

Chapter 1: Functional Description

System Functions

1.3.3 Watchdog

The system incorporates smart monitoring mechanisms that allow three of the processors to monitor each
other in order to detect abnormal operation. (Refer to Figure 1-6.) The audio processor functions as the
master watchdog processor and ensures the main application processor is responding normally. If the
audio processor detects abnormal functioning of the main processor it opens the heater safety relay and
activates a high priority alarm.

The main application processor ensures the heat control processor is responding normally. If the main
application processor detects abnormal functioning of the heat control processor it opens the heater safety
relay, activates the high priority alarm and displays a system fail message. A power cycle is required to
return the system to use.

An independent hardware circuit monitors the audio processor to ensure it is functioning normally. In the
event the audio processor does not respond normally the hardware circuit will reset the audio processor
causing a system fail condition. A power cycle is required to return the system to use.

Note: A system failure on the screen indicates the main application processor has detected abnormal

function in the system. A blank screen with a high-priority alarm indicates a problem with the main
application processor. Refer to “4.4 Troubleshooting Tables” for more information.

1.3.4 Battery Management

A lithium ion rechargeable battery is located on the Control Board. The audio processor provides charge
control and monitoring of the battery. (Refer to Figure 1-7.) The battery management integrated circuit
provides proper charging profile to prevent damage to the battery. The battery management circuitry
prevents over-discharge of the battery and system damage in the event of reverse polarity installation. In
the event of battery failure or low charge, a “super” capacitor provides one cycle (ten minutes) of power fail
indication.

1.3.5 Power Fail

The next paragraph assumes loss of AC power and resulting loss of DC power.

A power fail is detected when the audio processor (refer to Figure 1-8) senses the 3.3 Volt power supply
below normal operating level with the stand-by switch on. This will result in a shut down of the main
application processor and initiate a power fail alarm for a minimum of 10 minutes. The lithium ion battery or
the “super” capacitor provides power for the alarm. The audio signal for a power fail alarm is a repeating
sequence of 3 beeps from a piezoelectric buzzer on the Alarm Light Board. The visual signal is one LED on
the Alarm Light Board.

The heat control processor on the Power Board has an independent circuit to detect a drop in 12 Volt power
below normal operating levels. In the event of low 12 Volt power the heat control processor will initiate a
controlled shutdown of the heater circuit. In the event of an internal malfunction resulting in loss of one
level of DC power, one or more of the processors will shut down causing the smart monitoring function to
initiate a system failure.

1.3.17 Equipment Grounding

1.3.17.1 Grounding and Insulation Design for Safety

The grounding and insulation design of the Giraffe and Panda Warmers ensures all mains circuitry is
separated from the operator and patient by one of two methods:

• Basic insulation with a grounded metal barrier

• Double/reinforced insulation

The radiant heater reflecting dish, heater duct, electrical enclosure, and elevating base all rely upon basic
insulation of the wires and a grounded metal barrier.

The heater head housing and main bracket (on elevating base models) rely on double/reinforced insulation.
For the heater head housing, the two parts of the housing along with the wire insulation form a double
insulation system. For the main bracket, a sheet of insulating material is fitted between the bracket and the
elevating column. This insulation, along with the insulation on the wires of the elevating base form a double
insulation system.
