OPERATOR’S MANUAL FOR INFANT INCUBATOR
EDITION/REVISION B/0
TABLE OF DEFINITIONS AND SYMBOLS
TECHNICAL DEFINITIONS
SKIN TEMPERATURE SENSOR: A sensing device including the link with the equipment intended
to measure the infant’s skin temperature.
INCUBATOR TEMPERATURE: Air temperature at a point 10cm above and centered over the
mattress surface.
CONTROL TEMPERATURE: The temperature set at the temperature control.
AVERAGE INCUBATOR TEMPERATURE: The average of the maximum and minimum Incubator
temperatures achieved during Temperature Condition.
STEADY TEMPERATURE CONDITION: A condition which is reached when the temperature does
not vary by more than 1℃ over a period of 1 hour.
TEMPERATURE ALARM CHECKOUT STATE: The difference between real temperature and
control temperature is within ±0.5℃ and such state lasts for over 10 minutes. The equipment must
stay in such state when check up the alarm about temperature.
TEMPERATURE UNIFORMITY: The amount by which the average temperature at each of four
points 10cm above the mattress surface differs from the Average incubator Temperature at steady
Temperature Condition. The four points are the centers of four quadrants formed by lines that
divide the width and length of the mattress surface.
TEMPERATURE VARIABILITY: The variability of the Incubator Temperature that will be observed
over a one hour period after Incubator Temperature Equilibrium has been reached.
TEMPERATURE RISING TIME: The time required for the Incubator Temperature to rise 11℃,
when the Air Control Temperature is at least 12℃ above ambient.
STEADY HUMIDITY CONDITION: A condition that the disparity between the indicated humidity
value and control value is less than ±5%RH, and maintains over 2 min.
NOTE, IMPORTANT, CAUTION AND WARNING
NOTE: A note is inserted in text to point out procedures or conditions, which may otherwise be
misinterpreted or overlooked. A note may also be used to clarify apparently contradictory or
confusing situations.
IMPORTANT: Similar to a Note but be used where greater emphasis is required.
CAUTION: A caution is inserted in text to call attention of a procedure which, It not followed
exactly, can lead to damage or destruction of the equipment.
WARNING: A warning is inserted in text to call attention to dangerous or hazardous conditions
inherent to the operation, cleaning, and maintenance of the equipment which may result in
personal Injury or death of the operator or patient.
