Draeger 7510
Dräger · Model 7510
Designed for premature and sick newborn babies The Intensive-care Incubator 7510 is designed for babies of up to 6 months old whose lives are at risk and following surgery. Its most important features, compared with models 7010 and 7310, are: larger Plexiglass hood, hinged flaps (spring flaps) removable and swivelable reclining surface, and X-ray cassette drawer. Minor surgical procedures on children, radiology, intubation and ventilation are all quite simple in the Intensive- care incubator 7510.
Key tips
- ·Never skip temperature-accuracy verification to save time - it's the one check that directly prevents burns.
- ·Hose/blanket connector wear is the most common real fault and the easiest to miss on a quick visual check.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Air- or radiant-heater control fault
HighSymptoms: Chamber / patient will not reach or hold the set temperature, temperature alarm, self-test / "Check" fault.
Root cause: Heater element / infrared rod, the air- or skin-temperature sensor, the fan (incubator), or a control-board fault.
Skin-temperature (servo) control fault
HighSymptoms: Servo mode does not regulate to the skin probe, deviation alarm, probe-fault alarm.
Root cause: Damaged skin temperature probe or its connector, or the servo-control circuit.
Alarm / audible / power-fail-alarm fault
MediumSymptoms: No or quiet audible alarm, alarm lamp does not light on the self-test.
Root cause: Buzzer / speaker or the alarm board - a safety-critical failure.
Humidity / airflow fault (incubator)
MediumSymptoms: Set humidity not reached, uneven chamber temperature, airflow alarm.
Root cause: Humidifier reservoir / heater, or a worn circulation fan / blocked air filter.
Mattress / weigh-scale / tilt / access-port fault
LowSymptoms: In-bed scale inaccurate, tilt mechanism stiff, port latches or iris sleeves worn.
Root cause: Load cell, tilt actuator, or worn access-port hardware.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Hose / blanket connector inspection
- ·Temperature-accuracy verification
- ·Annual electrical safety test
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Chamber or patient temperature will not reach / hold the setpoint
- Run the readiness / self-test and confirm the alarm lamp and buzzer.
- Set a target and confirm the unit reaches it; compare to an independent calibrated reference.
- Check the circulation fan runs and the air filter is clean (incubator).
- Verify the heater element / infrared rod draws current.
- Replace the air / skin temperature sensor, the heater element or the infrared rod as isolated.
Symptom: Skin (servo) control does not regulate / probe-fault alarm
- Fit a known-good skin temperature probe with good skin contact.
- Check the probe connector and cable.
- Verify the servo regulates to the probe with a warm reference.
- Replace the probe.
- Refer the servo-control circuit if it still will not regulate.
Symptom: No or quiet audible alarm / alarm lamp fails the self-test
- Run the self-test / check function and watch the alarm lamp and listen for the buzzer.
- Check the buzzer / speaker and its connector.
- Check the alarm board.
- Replace the buzzer or alarm board - a failed alarm is a safety fault.
- Confirm all alarm conditions annunciate before returning to service.
Symptom: Humidity not reached / uneven chamber temperature (incubator)
- Check the humidifier reservoir level and the humidifier heater.
- Confirm the circulation fan runs and the air filter is clean.
- Check for a chamber / access-port seal leak.
- Verify humidity with an independent reference.
- Replace the humidifier heater or the circulation fan as isolated.
