Section 2 Introduction, Features, and Specifications
The transport incubator provides transport of high-risk, premature, low birth-weight, or critically ill newborns. It provides a means to control air temperature, oxygen concentrations, and relative humidity. A doublewalled hood permits full visibility and provides 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 to the newborn. Tubing access grommets are on both sides of the front access panel and at the head end (left) panel. An observation lamp is also included. The incubator is designed to operate from either a sine or square wave AC power source. In addition, the incubator can operate from an external 12V DC or 28V DC source or integral 12V DC batteries. Whenever the unit is connected to an AC voltage source and the main Power switch is set to the ON-1 position, the batteries automatically charge. A comprehensive visual and audible fault alarm system, with a test function to verify proper alarm operation, is included along with a Battery Status indicator.
System Overview A forced air circulating system controls temperature, humidity, and oxygen concentration. A motor-driven impeller draws a controlled amount of room air through the air/oxygen intake filter. Supplemental oxygen, introduced through the oxygen inlet connector on the left side of the unit (when viewed from the front of the unit), displaces a portion of room air to maintain the total gas intake (including oxygen) at the same level. Since the impeller/filter controls the amount of room air and the flow meter setting controls the amount of oxygen, a predictable oxygen concentration within the incubator can be attained. In addition to drawing fresh, filtered air into the incubator, the impeller recirculates at a much greater flow than that of the fresh gas inflow. The air is directed over the humidity sponge for humidification, when used. When the access panel of the hood is closed, the air enters the infant Transport Incubator (Model TI500) User Manual (67 990 70)

Introduction
compartment up through the slots at the right end of the housing. After circulating within the infant compartment, the air is then circulated down the left end of the housing, past the temperature sensing probe, and back to the impeller. The transport incubator is designed to operate from one of three power sources. The three sources are used in the following order: If external AC is not available, the incubator switches to external DC. If that is not available, it switches to its internal batteries. The batteries can be charged only when the unit is operating from an AC source.
Temperature Control A temperature sensor, located in the recirculation air path, and a proportional control circuit, which determines the heater output required to maintain the desired incubator temperature, regulate the incubator temperature. The number of Heater indicators lit on the control panel indicate the relative amount of heat provided. The incubator temperature can be maintained from 21.5°C (70.7°F) to 38°C (100.4°F), as selected with the temperature controls on the control panel. The temperature, as sensed by a sensor located within the housing, is compared to the setpoint. Control circuitry, which proportions the heater output to maintain the setpoint, supplies the information from this sensor. The temperature is displayed on the front panel. The setpoint is preset to 36°C (96.8°F) ± 0.15°C, and, unless the setting is changed, the incubator heats to this temperature. The Set Temp controls on the control panel can change the setpoint to a prescribed temperature (see “Operation During Use” on page 5-16). An additional sensor within the housing serves as a backup to limit the incubator maximum air temperature to 39°C (102.2°F) ± 0.5°C. At this limit, the High Temperature 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 audible alarms are functional. • High Temperature-A sensor located below the deck sounds this alarm when the incubator temperature is equal to or greater than 39°C (102.2°F) ± 0.5°C. A flashing High Temp indicator and a tone

indicate a High Temperature alarm. Internally, the heater turns off. To silence this alarm for 5 min, press the Silence/Reset key.
• High Heater Temperature-The Heater Temperature indicator flashes along with an intermittent alarm to indicate that the heater temperature has exceeded 77°C (170.6°F). When this condition occurs, the heater and heater indicators turn off. To silence this alarm for 5 min, press the Silence/Reset key. • Airflow-The Airflow indicator flashes along with an intermittent alarm to indicate that the fan impeller has stopped rotating or is missing. When this condition occurs, the heater and heater indicators turn off. To silence this alarm for 5 min, press the Silence/Reset key. • Low DC-The Low DC indicator flashes, and an intermittent alarm sounds, to indicate that the incubator DC power source has fallen below a predetermined value. • Power failure-An internal battery that is separate from the battery powers the Power Failure alarm circuit. The alarm lights and a continuous tone sounds if AC power is lost and no external DC or internal battery is present. To silence this alarm for 5 min, press the Silence/Reset key. If the power source switches from AC to battery or external DC to battery, the Power Failure alarm lights, and an intermittent tone sounds. To reset the alarm, press the Silence/Reset key.
