Operating Precautions

[1] Operating Precautions

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 injury, damage to equipment or a fire will result if the instructions given below are not followed.

Only those who have been trained properly 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 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 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 difficult 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 port 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 port 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.

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.


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 arterial 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 effects.

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

The screws or fixed parts may become loose.

1-2.

WARNING

Death or serious injur y 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 incubator.

Use only oxygen for medical use.

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

앫 Do not place a body warmer, a flashlight, oils and fats, or flammable vaporizable matters in the incubator.

앫 Use pure cotton for the infant’s clothing, bed sheets, etc. Do not use any material that is easily charged with static electricity.

앫 Use pure cotton or fire-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.

앫 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.

앫 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.

9

10


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.

앫 Do not get the power cord caught between the unit and the wall, a shelf or the floor.

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

앫 Do not put anything heavy on the power cord.

앫 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 sufficiently.

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.

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.

The doctor is responsible for making a decision on transporting a premature infant. Watch the infant continuously during transport.

Transporting a premature infant is associated with a risk of intracerebral hemorrhage due to jolting during transport.

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, be sure to always preheat the unit in order to keep the incubator air temperature stable.

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

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

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.

70~100% hypoxia was induced in healthy male and female adult volunteers with light skin and dark skin. Accuracy was checked in no motion conditions against a laboratory CO-oximeter and an ECG monitor.

Variability distribution at this accuracy was 1SD. 1SD covers 68% of all data.

70~100% hypoxia was induced in healthy male and female adult volunteers with light skin and dark skin. Accuracy was checked by 1~2cm tapping 2~4 times per second and by 2~3cm irregular tapping 1~5 times per second against a laboratory CO-oximeter and an ECG monitor. Variability distribution at this accuracy was 1SD. 1SD covers 68% of all data.

❋ 4 In a laboratory test, in the range of 70~100% SpO

2

, accuracy in low perfusion conditions was checked against the Biotec Index2 Simulator and the Masimo Simulator, both of whose signal strength is 0.02% or more and permeability 5% or more. Variability distribution at this accuracy was 1SD. 1SD covers 68% of all data.

❋ 5 The materials accessible to the patient and the user comply with ISO 10993-1.

❋ 6 All the sensors and patient cables that can be used with this device have been tested and verified by using the

Masimo/MX-1 module pulse oximeter technology.

❋ 7 Since the measurements taken by the pulse oximetry equipment are statistically distributed, only about twothirds of them fall in the accuracy (Arms) range of values obtained with a CO-oximeter.

❋ 8 Even if the power supply is interrupted due to power failure, disconnection of the power plug, or some other cause, the preselected settings will be retained in the memory. When the power supply is resumed, the unit will start operation with the last selected settings.

❋ 9 The above specifications apply when the sensor and the patient cable specified by Atom are used. For information on the sensor and the patient cable specified by Atom, contact your local Atom representative.

❋ 1 This device is calibrated to display functional oxygen saturation.

❋ 2 Subjects used to validate SpO 2 measurement accuracies were healthy and recruited from the local population. Comprised of both men and women, subjects spanned a range of skin pigmentations and ranged in age from 18-50 years old. Accuracy specifications are based on controlled hypoxia studies with healthy nonsmoking adult volunteers over the specified SpO 2 range(s). Pulse oximeter SpO 2 readings were compared with SaO 2 values of drawn blood samples measured by hemoximetry. All accuracies are expressed as 1SD.

Pulse oximeter equipment measurements are statistically distributed; about two-thirds of pulse oximeter measurements are expected to fall in this accuracy (Arms) range. Because scatter and bias of \pulse oximter

SpO 2 and blood SaO 2 comparison commonly increase as the saturation decreases, and accuracy specifications are calculated from data spanning the stated range, different accuracy values may result when describing partially overlapping ranges.

❋ 3 Reading accuracy in low perfusion conditions (detected IR pulse modulation amplitude 0.03~1.5%) was verified by using signals supplied by a patient simulator. SpO 2 and pulse rate values were varied across the monitoring range over a range of weak signal conditions and compared with the known true SpO 2 and pulse rate values of the input signals.

❋ 4 The materials accessible to the patient and the user comply with ISO 10993-1.

❋ 5 All the sensors and patient cables that can be used with this device have been tested and verified by using the

Nellcor/NELL-1 module pulse oximeter technology.

❋ 6 Even if the power supply is interrupted due to power failure, disconnection of the power plug or some other cause, the preselected settings will be retained in the memory. When the power supply is resumed, the unit will start operation with the last selected settings.

❋ 7 The above specifications apply when the sensor and the patient cable specified by ATOM are used. For information on the sensor and the patient cable specified by ATOM, contact your local Atom representative.

*b The ISM compliance level in the ISM frequency band between 150kHz and 80MHz and in the frequency range 80MHz to 2.5GHz are intended to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas. For this reason an additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in these frequency ranges.

*c Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radio, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Inuc i is used exceeds the applicable RF compliance level above, the Inuc i should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Inuc i .

*d Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
