Section 2 Introduction, Features, and Specifications Introduction The Introduction subsection provides a system overview and functional description of the Isolette® Infant Incubator, Models C2000 and C2000e.

System Overview The Isolette® Infant Incubator, Models C2000 and C2000e is a modular controller-based incubator, which enables simultaneous control of temperature, oxygen and humidity parameters affecting the infant. The incubator hood and shell assemblies are mounted on a variable height adjustable (VHA) stand or fixed height (FH) stand. Humidity System (Optional) When installed, the built-in humidifier provides humidification of the incubator from 30% to 95% relative humidity (RH) in 1% increments. When the humidity system senses an absence of water an audible and visual Low Humidity alarm occurs. The humidifier is a three-part system consisting of a humidity reservoir, manifold assembly and evaporator assembly. Humidity Reservoir

The humidity reservoir has a 1 liter capacity. The reservoir permits visual inspection of the water level. It is located in a drawer in the front of the incubator shell. When the drawer is closed and the latching handle is engaged, the reservoir is connected to a manifold. Manifold Assembly

The manifold assembly allows the water to flow into the metering valve and the evaporator assembly. Evaporator Assembly

The metering valve regulates the flow of water to the evaporator chamber to maintain a constant level of water, ensuring optimum responsiveness of the evaporator heater. The evaporator assembly raises the temperature of the water to the boiling point, causing vaporization. Any waterborne bacteria are killed, preventing transfer into the patient compartment. The rate of vaporization is determined by the level of power transmitted to the evaporator heater. The sensor module located within the hood environment houses the humidity sensor, which sends information to the controller module. The controller module regulates the output of the evaporator. Oxygen Control System (Optional) When installed, the oxygen (servo) control system adjusts the flow of oxygen within the incubator hood with a valve and an oxygen sensor module. The sensor module houses two independent oxygen fuel cells. When the sensor module is outside of the hood during Oxygen Control mode, audible and visual alarms are enabled, and the flow of oxygen is interrupted.

Weighing System (Accessory) NOTE: The description in this section does not apply to the EU (Type NAWI) weighing system. Refer to the Isolette® Infant Incubator, Type - NAWI, Weighing System Quick Reference Guide. When installed, the weighing system is located in a platform under the mattress. The scale contains two load beams, which perform the actual weighing function. The controller processes the load beam information and displays the weight in kilograms or pounds in the Trend/Alarm window. The Weight softkey allows for repeated re-weighing of the infant after the weighing routine has been initiated. System prompts are displayed in the Trend/Alarm window, during the weighing procedure. Uninterruptible Power Supply (UPS) (Optional) When installed, the UPS system provides an on-line uninterruptible back-up power supply to the incubator, which can also be used for intra-facility transport. With batteries fully charged, the power available from battery backup is sufficient to maintain a C2000e incubator in operation for 30 min in a 20°C ambient at a set point of 39°C in the Air mode, without oxygen or humidity control, or additional loads drawn from the accessory outlets. Battery back-up usage occurs during power failure or while transporting an unplugged incubator within the facility. The UPS system consists of two main components: the electronics control module and battery pack module. The battery pack module consists of 3 sealed gel cell batteries that are charged by the electronics module. The electronics module is responsible for monitoring, distributing and controlling the power delivered to the incubator. The UPS system operates in three modes: line, back-up and bypass. Refer to the table below: Modes Line Back-up Bypass

Functional Description The temperature, humidity, and oxygen concentration is controlled by the forced air circulation system. A controlled amount of room air, approximately 7 lpm, is drawn through the air intake filter by the motor-driven impeller located in the shell. The impeller internally recirculates air at a much greater flow than that of the fresh gas inflow. The total inflow of fresh and re-circulated air is directed around the heater. The air enters the infant compartment up through the slots at the front and rear of the main deck. It then passes between the front and rear inner walls. The air circulates past the sensor module containing the temperature sensing probe, which encapsulates the air temperature control thermistor and a high air temperature alarm thermistor. After circulating within the infant compartment, the air is then recirculated down through a slot in the right end of the main deck, and back to the impeller. When the front and/or rear access panel(s) of the hood is/are open, the air continues to flow upward past the opening, creating a warm air curtain. This curtain minimizes the drop in air temperature in the incubator. Temperature is regulated by using either incubator air or skin temperature. The front panel keys enable the user to select the desired Air or Skin mode. In either mode of operation, the heater output is proportional to the amount of heat required to maintain the desired temperature. The Air and Skin modes are described below. Air Mode

In the Air mode, the air temperature can be maintained from 20.0°C (68.0°F) to 37.0°C (98.6°F) as selected by the Up and Down Arrow keys on the front panel. In Temperature Override mode, the temperature can be maintained from 37.0°C (98.6.0°F) to 39.0°C (102.2°F). The incubator air temperature is monitored by a probe located in the sensor module and compared with the air set temperature parameter. The information from this probe is supplied to the heater control circuitry, which regulates the heater output to maintain the air temperature setting. The actual air temperature is shown in the Temperature window. A second sensor within the air temperature probe serves as a backup to limit the maximum incubator temperature. If the high temperature limit is reached, the heater shuts off. The infant temperature is a function of: 1) the air temperature and 2) the ability of the infant to establish and maintain his/her own temperature. A small infant, or one with underdeveloped homeostatic control, may not be able to maintain a stable temperature at the desired level.

2-3

Skin Mode

In the Skin mode, the Up and Down Arrow keys on the controller front panel are used to select the infant temperature from 34.0°C (93.2°F) to 37.0°C (98.6°F). In Temperature Override mode, the temperature can be selected from 37.0°C (98.6°F) to 38.0°C (100.4°F). A temperature sensing probe is attached directly to the skin of the infant. The information from the probe is supplied to the heater control circuitry, which proportions the heater output to maintain the skin set temperature. The air temperature is still shown in Skin mode, but for information purposes only. If the Air mode is selected while the skin probe remains connected, the skin temperature parameter continues to display the actual skin temperature. However, it does not control the incubator temperature. The sensor module is equipped to accept two skin probes. To control the incubator temperature in the skin mode, insert a skin probe into the skin probe 1 connector (see “Controls, Indicators and Connectors” on page 5-1). When a second skin probe is connected to the sensor module while operating in the skin mode, an alarm sounds and the message Remove Skin 2 Probe is displayed. To connect a second skin probe, select the Air mode first. The controller then displays the respective Skin 1 and Skin 2 temperatures monitored by the skin probes. If Probe 1 is disconnected from its receptacle while in the Skin mode, the skin temperature parameter goes blank on the display, an alarm sounds, and the heater turns off.
