Operation Precautions

Operation

Precautions

Before each use, check that the unit is ready for operation (see page 26).

Make sure that all hoses and cables are routed correctly and safely without obstruction! Otherwise: Risk of extubation! Danger of disconnection!

Lively patients must be observed with particular care.

When the canopy, front ﬂap, hand ports are opened or when the bed has been pulled out or when the tubing grommets are removed, the patient must be observed constantly to make sure that he or she cannot fall out of the incubator.

Do not lean or apply weight on the bed when it has been pulled out. Maximum load 5 kg

Do not use the X-ray drawer as writing support or bed for the patient.

Allow time for the incubator to warm up before use (page 107).

Additional external heat sources, such as sunlight, heat lamps, spotlamps and electric cushions should be avoided! They cause the temperature inside the Caleo® to rise in an uncontrolled manner.

The baby’s core temperature must be regularly monitored with an independent thermometer.

The castor with direction lock does not have a brake. When parking the unit, apply the brakes of all braked castors.

When treating larger babies, the higher heater output may cause the air temperature in the Caleo this case the double wall should be removed.

The room temperature must be at least 3 oC lower than the air temperature in the Caleo® incubator.

When treating twins, pay attention to the risk of crossinfection!

Fire hazard from supply of O2

— No naked lights or smoking. Textiles, oil and plastics can

very easily catch fire and burn rapidly in an O2 enriched atmosphere!

— All fittings and seals in contact with oxygen must be kept

free of oil and grease! — Open valves on O2 cylinders slowly! — Do not use Caleo® in the presence of flammable

anaesthetic gases or disinfecting agents. Risk of explosion! — Do not use or keep flammable liquids, such as alcohol,

ether or acetone, in Caleo®! — Do not use any electrical equipment in the patient capsule,

unless this equipment is expressly designed for use in

explosion-hazard areas. — Use the original Caleo® air filter (MX 17 015) only!

Note the physiological risks from O2.

incubator to rise. In

The conclusions to be drawn from the measured skin temperature are the responsibility of the attending physicians.

Skin temperature control mode must not be used on babies who are in shock or who have a high temperature!

Skin temperature control mode must not be used on twins, since the Caleo® controls only the temperature for one baby. Risk of hypothermia or overheating! For twins, the air temperature control mode must be used.

Make sure that you do not confuse the positions for the skin temperature sensors. Skin temperature control is regulated by the yellow skin temperature sensor (T1). If this sensor is stuck to the wrong part of the body, the patient may be excessively warmed!

Do not place any cloths over the hot air duct. The temperature control system would be disrupted, causing a risk of burning if the air from the hot air duct is channelled directly to the patient.

During O2 therapy, monitor the O2 concentration with a separate O2 monitor.

The air in the incubator may only be enriched with O2 when prescribed by a doctor.

O2 enrichment must be controlled on the basis of the arterially measured oxygen partial pressure in the patient’s blood. Otherwise, there is a danger of hyperoxaemia (damage to the eyes) or hypoxaemia (brain damage).

Medicaments and similar substances must not be atomised in the patient capsule. Correct functioning of the incubator may be impaired by the precipitation of atomised substances.

Do not cover the sensor unit and do not hang anything from the slits in the sensor unit. Keep the slits of the sensor unit free of impurities.

In the event of a power failure, the C capsule may rise due to an insufﬁcient supply of fresh air. Pay attention to the risk of C

2 poisoning!

2 level in the patient

Operation

Precautions

The central alarm light can be deactivated (see page 124). Always check the alarm LEDs on the control panel and the associated alarm beep signals.

Front ﬂaps

When closing the front ﬂaps, make sure that the patient is not lying in the closing path.

The front ﬂaps are not properly shut until the red latches are no longer visible.

When opening and closing the front ﬂaps, make sure that the hoses and cables are not caught in the moving double wall!

Side ﬂaps

When opening and closing the side ﬂaps, make sure that the hoses and cables are routed safely and clear of any obstructions!

The side ﬂaps are not properly shut until the red latches are no longer visible.

Canopy

The canopy must not be used as a shelf for laying clothing, instruments etc. Before moving the canopy, make sure that nothing has been laid on top of it. When ﬁtting and removing the canopy cover hold it ﬁrmly in your hand. The canopy installation catch must engage correctly. Do not lift the canopy when engaged. Do not tilt the canopy forwards. When closed, make sure that the canopy cover sits ﬁrmly in place!

When ﬁtting accessories, please note:

● The accessory equipment must not collide with the unit

when adjusting the tilt angle and height of Caleo®.

● The accessory equipment on the handle side must not

move with the main unit during height adjustment of Caleo® (page 109).

Observe the maximum loads. Danger of overturning the unit!

Kangaroo mode

The patient’s core temperature must be monitored constantly, because it is outside the controlled climate. Particular attention must be paid to critical patients vital parameters.

When using Phototherapy

Absorption of light through the baby’s skin will supply heat, which may increase the baby’s core temperature.

For this reason: — Roughly 15 minutes before starting phototherapy,

decrease the air temperature setting for the incubator air by about 2

C. — Decrease the set value for humidity. — Room temperature must be at least 3 oC lower than the air

temperature in Caleo®. This value applies to Dräger Type 4000 phototherapy units. When using other phototherapy units, especially units without a built-in fan, the temperature in the Caleo® incubator may rise even more sharply.

— Phototherapy may only be used with a stand!

Double wall

To ﬁt and remove the double wall, remove the canopy from Caleo®.

Tilting/height adjustment

Ensure that the cables and hoses are routed correctly and safely without obstruction. Hoses and/or cables risk being trapped when tilting the Caleo® and when opening and closing the front ﬂap.

Control unit

Do not mechanically load the cable by e.g. hanging appliances from it. If the control unit is mounted on the handle side, never remove the cable from the cable guides on the basic pole. Do not place any liquid containers above the control unit.

The core temperature of the baby must be monitored with particular care during phototherapy!

The supply of ﬂuid to the baby must be increased, e.g. by parentral infusion, to compensate for the increased loss of water during phototherapy.

The phototherapy lamp and Caleo® canopy must not be covered with cloths, aluminium foil or other materials in

order to boost the phototherapeutic effect – risk of heat build-up, as the incubator cannot be adequately cooled with ambient air.

Danger of overheating the patient.

In-house transport

An even ﬂoor surface must be ensured when moving the Caleo® incubator. The incubator must not be used outside the hospital building, as the castors may be damaged or dislodged.

The Caleo

may only be moved when empty.

Operation Precautions

High noise levels

Excessive noise levels that can disturb the patient may be caused by:

— using O

2 head boxes and delivering pressurised gases,

— wear on the bearings of the fan motor, — placing objects on the canopy.

● Observe the specified maintenance intervals – see

page 95.

Cleaning mode may only be used when Caleo® is empty. After use, allow Caleo® to cool down before dismantling.

Risk of burning when touching the heater!

Electrical safety

Do not use multiway adapters to connect the power supply of the Caleo®!

The patient leakage current may rise above the permitted limits if the protective earth conductor fails while equipment is connected to the socket strip. In such cases, the risk of electric shock cannot be excluded.

Only use electromedical ancillary equipment conforming to IEC / EN 60601-1.

When using the integrated socket strip: take into account the total leakage current and total current consumption! See "Technical Data" on page 106.

Caleo® does not monitor the power supply to external devices.

Mobile telephones must not be used within 10 metres of the incubator. Mobile telephones can interfere with the functioning of electromedical equipment and therefore endanger the patient!

* Dräger medical equipment conforms to the interference immunity

requirements laid down in product-speciﬁc standards or in EN 60601-1-2 (IEC 60601-1-2). However, depending on the design of mobile phone and the application situation, ﬁeld strengths exceeding the values laid down in the speciﬁed standards may be generated in the immediate vicinity of mobile phones, thereby causing interference and malfunctions.

Operation Using skin temperature control

Using skin temperature control

Immediately before using the yellow skin temperature sensor or the white peripheral sensor, insert it in the yellow or white socket and wait for the measurement signal to appear on screen.

1 Measurement signal from the yellow skin temperature

sensor (T1)

2 Measurement signal from the white peripheral temperature

sensor (T2)

If no measurement signal appears, the sensor must be replaced (page 101).

Using skin temperature measurement in air temperature control mode or skin temperature control mode.

Connect the temperature sensors for measuring the skin temperature and peripheral temperature:

● Plug the yellow skin temperature connector into the yellow

socket on the sensor unit (skin temperature, T1). When using skin temperature control, the control functions refer to this sensor.

● Plug the connector of the white peripheral temperature

sensor into the white socket on the sensor unit (peripheral temperature, or skin temperature of the twin in the case of air temperature control mode, T2).

● Route the sensor cable through one of the flexible tubing

grommets.

● Remove the protective foil from the adhesive pad and place

the skin temperature sensor on the pad.

● Using the adhesive pad, attach the sensor tip to the

appropriate part of the baby’s skin.

235 37 570

125 37 570

Positioning the skin temperature sensor (yellow): If the baby is lying on his/her back:

● Attach the yellow sensor to the abdomen, near the liver.

If the baby is lying on his/her belly:

● Attach the yellow sensor to the back, preferably near the

kidneys.

Positioning the peripheral temperature sensor (white):

● Attach the white sensor to the extremities, preferably the

foot or arm.

Do not use the skin temperature sensor (yellow) or peripheral temperature sensor (white) to measure rectal temperature!

Regularly check that the skin temperature sensor is correctly attached to the patient’s skin. If the skin temperature sensor has fallen off, it will measure the air temperature, resulting in possible overheating of the patient

(although the air temperature would not rise above 39 oC).

When a skin temperature sensor is attached but "air temperature control" is activated, the measured skin temperature is displayed. However, in this case, the temperature is not controlled as a function of skin temperature!

Changing over between air/skin temperature control

Do not use skin temperature control mode on babies in shock, as their skin temperature is much lower than normal. Skin temperature control would increase the air temperature by too much and would endanger the patient. Use air temperature control – see page 38.

Do not use skin temperature control mode on babies with a high temperature, as their skin temperature is much higher than normal. The control function would overcool the incubator, resulting in the risk of hypothermia.

Do not use skin temperature control mode on twins, because Caleo® only controls the temperature for one baby. Danger of hypothermia or overheating!

Operation Weighing scale

Weighing scale

The weighing scale is located directly underneath the bed. In the weighing process, the entire bed and the items placed on top of it are weighed with the baby. However, these extras are deducted again as soon as the baby is lifted off the bed (tare weight), so that precise weighing of the baby is possible. Before weighing, check that the bed is fully pushed in and is in the horizontal position. The scales must be regularly checked by a test weight. The accuracy speciﬁed in the technical data of the scales is only obtained if the scales have been calibrated at the installation site.

The spirit levels show whether the bed is aligned horizontally.

1 Spirit levels for the horizontal alignment of Caleo

in the

transverse axis.

2 Spirit level for the horizontal alignment of Caleo® in the

longitudinal axis.

To align the bed horizontally see page 23.

During the weighing process, Caleo

must not be exposed

to any vibrations.

During the weighing process, no objects may be placed on the bed surface.

During the weighing process, no objects may be placed been the bed and the housing.

The weighing accuracy may be adversely affected when using the ventilation hose holder.

Risk of burns on contact with the heater

When the incubator is closed, the heater is still hot enough to cause serious burns for a long time after switching off (still approx. 70

Clean and disinfect the incubator thoroughly: — after each change of patient — at least once a week.

Clean and disinfect the accessories, such as the suction equipment and the ﬂowmeter in accordance with their separate Instructions for Use.

C after 1 hour).

Disinfecting/cleaning/sterilising

Use surface disinfectants for disinfecting. For reasons of material compatibility, use disinfectants based on — aldehydes — quaternary ammonium compounds.

Due to the chemical composition and direct effects on material compatibility, the following products are only suitable to a limited extent: — Halogen-releasing compounds — Strong organic acids —O2 releasing compounds.

Use only cleaning agent in autoclaves and other cleaning and disinfecting machines. Do not use any alkaline or chlorine releasing disinfectants, due to the risk of corrosion. As a general rule, the manufacturer's recommendations must be taken into account when choosing a cleaning agent. Liability for the speciﬁed use and for any material damage that may be caused by the product rests with the manufacturer.

Do not use any disinfectants or cleaning agents containing alcohol.

We recommend the use of disinfectants based on the current DGHM list (DGHM: German Society for Hygiene and Microbiology). The DGHM list (published by mhp Verlag GmbH, Wiesbaden) also gives the composition of each disinfectant. For countries where the DGHM list is not familiar, we recommend the types of disinfectant speciﬁed above.

The following surface disinfectants are recommended:
