ATOM MEDICAL CORPORATION

It is highly recommednded that you read this Manual carefully
and familiarize yourself with this Incubator thoroughly by
applying power to the empty unit and operating its various
features including temperature control, humidity control,
oxygen supply, etc. before placing the unit in actual service,
so that you may use it with confidence.

2-2-2 Power unit
This system detects minute variations in skin temperature with a
precision temperature probe attached to the infant's abdomen
and supplies an incubator temperature needed to keep skin tem-
perature at a preset level. It also maintains an optimum
environmental temperature by calculating an accurate balance
between the infant's skin temperature and the incubator tem-
perature so that low incubator temperature due to an attack of
fever and other causes may be prevented.

2-3 Air circulation system of
V-850 incubator
The air circulation system of V-850 ATOM Incubator is designed
to provide an optimum atmospheric environment for the infant
by precise temperature control,
supply.
humidification and oxygen
Room air and oxygen enter the unit through the filter and then
are mixed.

The air filtered into tne unit is sent to the heater where
it is heated appropriately as directed by the control and
then circulated in the incubator by the air circulating fan.
Part of the circulating air is humidified as it passes over
the humidity reservoir. Both humidified air and dry air,
whose flow rates are controlled by adjusting the hunidifica-
tion control sliding plate, enter the circulating-air rectifier
to be mixed. The direction of air is rectified in this cir-
culating-air rectifier. The air is then blown into the
incubator hood to provide even temperature and humidity dis-
tribution over the mattress.
This air circulation system maintains a slizht positive pre-
ssure inside the hood, and this assures effective isolation
4 when the ports are opened momentarily for access to the infant.

2-4 Double-wall effect and air circulation system of V-850W
incubator
M Double-wall effect
It has been widely reported in a number of articles that a
newborn infant placed in an incubator loses heat due to radi-
ation, convection, evaporation and conduction; of the four
factors, loss of heat due to radiation is the greatest,
accounting for almost 40% of total heat loss.
The mechanism of the double-wall incubator to prevent radiant
heat loss is to minimize such heat loss by making the tempe-
rature of the inner wall facing the infant within the incubator
as close to that of the incubator air as possible.
This air circulation system allows warm air to circulate effec-
tively between the inner and outer walls, thus adding to the
double-wall effect.
E Air-curtain effect
The air circulation system has warm air outlets all along the
front door to contribute to the uniform temperature distribu-
tion in the entire incubator compartment as well as to add to
the double-wall effect.
The warm air outlets operate continuously, emitting a curtain
of warm air even when the front door is open. Thus, the
incubator temperature will not drop by more than 2°C (with
the ambient temperature at 25°C), and during treatment or
operation the infant's temperature will remain constant.
