Introduction
Chapter 1: Introduction
Introduction
Overview
The Transport Incubator is for transport of high risk, premature, low birthweight or critically ill newborns. It provides a means to control air temperature and oxygen concentrations, and adds relative humidity. A double-walled hood provides full visibility and an effective thermal and sound barrier from the environment. Arm ports and door panels provide front and head access, and the mattress tray slides out of the head end for additional access. Tubing access grommets are on both sides of the front access panel and at the left-hand, head end panel. An observation lamp is also included.
The Transport Incubator operates from either a sineor square-wave AC power source. In addition, it can operate from an external 12V DC or 28V DC source or integral 12V batteries. The batteries automatically charge whenever the unit is connected to an AC voltage source and the main Power switch is set to the ON-1 position. A comprehensive visual and audible alarm system is included with a test function to verify proper alarm operation. A Battery indicator is also provided.
Operating Precautions
For additional operating precautions for the Transport Incubator and its accessories, refer to the Transport Incubator (Model TI500) User Manual
(usr038).
Features
Temperature Control
A temperature sensor, located in the recirculation air path, and a proportional control circuit, which determines the heater output to maintain the desired incubator temperature, regulate the incubator temperature. The relative amount of heat provided is indicated by the number of Heater indicators lit on the control panel. The incubator temperature can be maintained at 38.0°C (100.4°F) as selected by the temperature controls on the control panel. The temperature, as sensed by a sensor located within the housing, is compared with the setpoint. Control circuitry uses the information from this sensor to proportion the heater output to maintain the setpoint. The temperature appears on the front panel’s Temperature display.

Chapter 1: Introduction |
The initial setpoint is 36.0°C (96.8°F) ± 0.1°C. The incubator heats to this temperature unless the setting is changed. To change the setpoint to a prescribed temperature, use the Set Temp controls on the control panel. An additional sensor within the housing serves as a backup to limit the incubator’s maximum air temperature to 38.9°C (102.0°F) ± 0.5°C. At this limit, the High Temp alarm activates, and the heater shuts off.
Alarms
Each time the unit turns on, it automatically activates a test sequence to verify that the visual display and the audible alarm function. Each of the following six alarms has an indicator on the display and an audible alarm.
High Temperature Alarm
When the incubator temperature is ≥38.9°C (102.0°F), a sensor located below the deck sounds this alarm. A flashing High Temp indicator and an audible tone indicate a High Temp alarm. Internally, the heater turns off. To silence this alarm for 5 minutes, press the Silence/Reset key.
Sensor Alarm
Circuitry monitors the air temperature sensor and the air display sensor for shortor open-circuits or skin temperature probe shorts. A flashing Sensor indicator and an intermittent audible tone indicate a Sensor alarm. This alarm resets itself.
High Heater Temperature Alarm
A flashing Heater Temp indicator and an intermittent audible tone indicate that the heater temperature exceeds 77.0°C (170.6°F). When this occurs, the heater and Heater indicators turn off. To silence this alarm for 5 minutes, press the Silence/Reset key.
Airflow Alarm
A flashing Air Flow indicator and an intermittent audible alarm indicate that the fan impeller is not rotating or is missing. When this occurs, the heater and Heater indicators turn off. To silence this alarm for 5 minutes, press the
Silence/Reset key.
Low DC Alarm
A flashing Low DC indicator and an intermittent audible alarm indicate that the incubator’s DC power source is below the minimum specification value.
