INFORMATION APPENDIX

Operating Precautions

Operating Precautions[1]

Please follow the operating instructions described in this Service Manual & Parts List for the safe use of the unit. The unit should be operated only by those who have been trained and instructed properly in its operation. The unit should be operated only for its intended use.

1-1. DANGER

Death or serious injur y, damage to equipment or a ﬁre will result if the instr uctions given below are not followed.

Only those who have been properly trained should operate the unit.

Be sure to keep the admittance panels and the access ports closed when the unit is in use.

Using the unit with an admittance panel or an access port left open may cause the infant to fall out of the baby compartment. Be sure to close the admittance panels and the access ports when performing phototherapy on an infant inside the incubator.

Monitor the infant’s skin temperature when operating the unit.

If the incubator air temperature should rise during phototherapy, proceed with the phototherapy

in the radiant warmer mode or after placing the infant in a cot or an open-type incubator (an

infant warmer), as directed by the doctor.

Since a mature infant emits much heat, the incubator air temperature may rise if you place the infant in the incubator and perform phototherapy. The incubator air temperature may also rise if you use multiple phototherapy units at the same time or if the room temperature is high. In such a case, proceed with the phototherapy in the radiant warmer mode or after placing the infant in a cot or an open-type incubator, as directed by the doctor. Take sufﬁcient care when using a cot, as it becomes dif ﬁcult to observe the infant. Alternatively, placing an ice bag inside the incubator has the effect of decreasing the incubator air temperature. However, be sure to close the admittance panels and the access ports in this case also.

Do not leave the unit unattended when an admittance panel or an access port is open.

If an admittance panel or an access por t is left open, the infant may fall out of the baby compartment and get fatally injured. Never leave the unit unattended when an admittance panel or an access por t is open.

Stop using the unit immediately and seek repair if an admittance panel, a snap-open access

port or a press lever should be found loose or faulty in any way.

The infant may fall out of the baby compartment.

Never place a body warmer or any other possible ignition source in or near the unit.

Use of oxygen will increase the risk of explosion or ﬁre. Body warmers or other devices in which ﬁre is used or which will generate a spark may cause an explosion or a ﬁre if used near the unit.

Do not use the unit in the presence of a flammable anesthetic gas.

The unit may cause an explosion or a ﬁre if used in the presence of such a gas.

PLEASE READ WITHOUT FAIL

Operating Precautions

Do not use ether, alcohol or any other ignitable substance.

Even a small amount of ether, alcohol or other ignitable substances may cause a ﬁre when mixed with the oxygen in the incubator.

Do not hang any flammable materials on the radiant warmer.

It may cause a ﬁre.

Ground the unit securely.

Otherwise, a leakage current may cause an electric shock. In order to complete the ground connection, connect the power cord only to a properly grounded 3P power outlet including a ground terminal. Do not operate the unit if you have any doubt about its ground connection.

Do not use a device generating high frequency near the unit.

To prevent malfunction of the unit due to jamming, do not use electric surgical knives, portable and mobile communication equipment and other devices which generate high frequency near the unit during its operation.

Analyze arterial gas levels repeatedly when a high oxygen environment is required.

When the infant requires a high oxygen environment, it is extremely important and essential to periodically analyze ar terial gas levels in order to maintain the desired oxygen concentration in the incubator. Follow the doctor’s instructions in measuring the oxygen concentration because ignoring essential requirements may increase the risk of retinopathy of prematurity and other adverse ef fects.

Do not give a shock to the unit or let it hit anything.

The screws or ﬁxed parts may become loose.

The heaters are consumables. If the heaters are to be used beyond their expected life span,

overall repairs including replacement of parts must be carried out.

1-2. WARNING

Death or serious injury due to a ﬁre or an electric shock will result if the instructions given below are not followed.

Be sure to follow the doctor’s instructions in setting the incubator air temperature or the

infant’s skin temperature.

Be sure to follow the doctor’s instructions in setting the relative humidity in the incubator.

Be sure to follow the doctor’s instructions in supplying oxygen.

Be sure to follow the doctor’s instructions in setting the oxygen concentration in the incuba-

tor.

Use only oxygen for medical use.

Operating Precautions

Be sure to bear in mind the following precautions during oxygen supply.

• Do not place a body warmer, a ashlight, oils and fats, or ammable vaporizable matters in the

incubator.

• Use pure cotton for the infant’s clothing, bed sheets, etc. Do not use any material that is easily

charged with static electricity.

• Use pure cotton or re-proof materials for the clothing of doctors, nurses and ambulance staff who

handle this unit.

Bear in mind the following precautions while using oxygen supply equipment.

• If oil, grease or a grease-like substance should get in contact with pressurized oxygen, a violent

spontaneous ignition may occur. Do not let such substances stick to the oxygen pressure regulator, the oxygen cylinder valve, piping, connections and other parts of oxygen supply equipment.

• On a high-pressure oxygen cylinder, use only a tested pressure reducing valve or pressure regulating valve indicated speciﬁcally for oxygen supply. Do not use such a valve for any gas other than air or oxygen. It is dangerous to use a valve to supply a gas other than air or oxygen and then to supply oxygen again.

If the oxygen sensor should break or get damaged, the electrolyte inside may leak out of

the sensor. If you should come in contact with the electrolyte, wash it away immediately and

thoroughly with copious amounts of water.

Smoking is prohibited in the room where the unit is installed.

Do not place any possible ignition sources in the room.

Avoid damaging the power cord.

A damaged power cord may cause a ﬁre or an electric shock.

• Do not get the power cord caught between the unit and the wall, a shelf or the oor.

• Do not place the power cord near a heating apparatus or heat it.

• Do not put anything heavy on the power cord.

• Always grasp the power plug with your hand to remove the power cord from the power outlet. A

damaged power cord should be replaced immediately with a new one.

Use only the power cord supplied with the unit.

Otherwise, a ﬁre or an electric shock may result.

Before cleaning and disinfecting the unit, be sure to turn the power switch off, remove the

power plug, and allow the incubator air temperature and the heater temperature to drop suf-

ficiently.

Do not touch the power plug with a wet hand.

Touching the power plug with a wet hand may cause an electric shock.

Do not touch the heaters during use or shortly after use.

The heaters are so hot during use and shortly after use that you may get burned. Allow the heaters to cool down sufﬁciently before touching them.

Do not disassemble or modify the unit.

Disassembling or modifying the unit may cause a ﬁre, an electric shock or injury.

PLEASE READ WITHOUT FAIL

Operating Precautions

Do not install the unit where it will be exposed to excessive humidity, dust or steam.

Installing the unit in such a place may cause a ﬁre or an electric shock.

The power outlet should be located near the unit to prevent accidental contact with a trailing

power cord. Use a separate power outlet for each unit.

Do not put many loads on one power outlet.

In order to complete the ground connection, connect the power cord only to a properly

grounded 3P power outlet including a ground terminal.

Do not operate the unit if you have any doubt about its ground connection.

Ground peripheral electric equipment securely.

Never connect the unit to a power outlet other than that specified.

The unit should be serviced only by qualified personnel.

Be sure to inspect the unit at the start of each day.

Operating the unit without inspecting it at the start of each day may let a defect pass unnoticed and cause a potentially unfavorable outcome.

Check for conformity to the applicable standard if the unit is going to be connected to another

medical device for use as a system.

Accessory equipment connected to the analogue and digital interfaces must comply with the relevant IEC standards (e.g. IEC 60950 for data processing equipment). Furthermore all conﬁgurations should comply with IEC 60601-1-1. But the items that are not speciﬁed as part of the system should not be connected. Anybody who connects additional equipment to the signal input or signal output conﬁgures a medical system, and therefore should make the medical system comply with the requirements of 60601-1-1 on his or her own responsibility. If in doubt, consult your local Atom representative.

1-3. CAUTION

Injury or damage to surrounding objects may result if the instructions given below are not followed.

Be sure to clean and disinfect the unit before using it for the first time after purchase.

The unit is shipped without being disinfected.

During standby in the incubator mode, be sure to always preheat the unit in order to keep

the incubator air temperature stable.

During standby in the radiant warmer mode, be sure to always preheat the unit in order to

keep the mattress surface temperature stable.

Place the infant in the incubator only after the incubator air temperature has stabilized.

Operating Precautions

When feeding the cords and tubes into the unit, be very careful not to let them wind or tighten

around the patient.

Do not hang any cables or infusion tubes on the canopy or the canopy arm. Do not pass

them above the canopy.

Do not twist or pull the cords by force.

If any defect should be found, ask an expert for repair without attempting to repair it yourself.

Remove the power plug from the power outlet before moving the unit to another place or

when the unit is not going to be used for a long time.

Moving the unit to another place with the power plug connected to the power outlet will damage the power cord and may cause a ﬁre or an electric shock.

Remove the power plug from the power outlet before cleaning and disinfecting the unit.

Cleaning and disinfecting the unit with the power plug connected to the power outlet may cause an electric shock.

Install the unit on a stable surface.

Installing the unit on an unstable platform or a tilted surface will cause it to fall or drop and may injure someone. Therefore, before installing the unit, make sure that the place where the unit is to be installed is stable and strong enough to support the weight of the unit.

Install the unit out of reach of small children.

Do not operate the radiant warmer covered with a cloth, etc.

Operating the unit covered with a cloth or pressed tightly against a wall may cause a ﬁre or an electric shock due to overheating.

When performing phototherapy on the infant in the incubator, pay special attention to the

infant’s skin temperature and the incubator air temperature during the treatment.

The infant’s skin temperature and the incubator air temperature may rise due to the radiant heat generated by the phototherapy unit.

Do not install the unit in direct sunlight or near a heating apparatus.

the SatSeconds limit appropriately by taking into consideration the patient’s condition. For example, select a higher setting for monitoring an active patient whose %SpO2 values tend to ﬂuctuate greatly.

Maintenance Inspection

WARNING

CAUTION

Replacing the Oxygen Sensor3-4-2.

As part of daily inspection, check the oxygen sensor for any sign of deterioration or liquid leakage.

If any cracks should be found on the external surface, replace it immediately with a new one.

The oxygen sensor is a sealed device containing a potassium hydroxide electrolyte. The electrolyte

may leak out if the sensor should be damaged when dropped, etc. If the electrolyte should touch

your skin or clothes, wash it away with copious amounts of water. If it should get in your eye, wash

your eye immediately with copious amounts of water and consult the doctor.

Dispose of a used oxygen sensor in accordance with the appropriate disposal procedure.

Replace the two oxygen sensors at the same time.

If an oxygen sensor alarm remains on, the oxygen sensors may be defective. Replace the old oxy-

gen sensors with new ones.

Leave the oxygen sensor in the atmosphere for more than one hour after taking it out of its pack-

age. The sensor output is not stable immediately after the sensor is taken out of its package and

an oxygen sensor alarm may occur.

Avoid direct sunlight and high temperature when storing the oxygen sensor.

The life span of the oxygen sensor varies depending on the ambient conditions under which it is

used. It is recommended to replace an oxygen sensor when more than one year has passed since

it was taken out of its package.

Avoid mechanical shocks to the oxygen sensors when replacing them.
