Hospira Gemstar Yellow
Hospira · Model Gemstar Yellow
The GemStar Pump is a small and lightweight, single-channel infusion device designed for use in the home, in the hospital, or anywhere electronic infusion is required. The GemStar Pump can be powered by AC mains adaptor, rechargeable battery pack, docking station, or two disposable AA alkaline or lithium batteries. When powered by batteries, the GemStar Pump is ideal for ambulatory patients.
Key tips
- ·Free-flow protection must be verified on every PM - a failed anti-free-flow clamp is a direct overdose risk.
- ·Test occlusion alarms in both directions - failing to alarm when it should is more dangerous than a false alarm.
- ·Battery run-time complaints are the most common real-world nuisance call - a full charge/discharge cycle test catches most of them.
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.
Failure / error message stops delivery
HighSymptoms: The pump alarms and displays an error message / code and stops.
Root cause: A subsystem fault indexed in the service manual - motor / drive, a sensor, set-detection, or a board.
Occlusion alarm / pressure fault
MediumSymptoms: Repeated occlusion alarms, delivery stops, or an occlusion is missed.
Root cause: Kinked or clamped line, a closed roller clamp, a positional patient tube, pressure-sensor drift, or an improperly loaded set.
Air-in-line alarm
MediumSymptoms: Frequent air-in-line alarms, delivery stops.
Root cause: Air in the set, an improperly loaded set, or an ultrasonic air-detector fault.
Flow-rate accuracy drift
MediumSymptoms: Delivered volume outside tolerance on the annual test, especially at low rates.
Root cause: Worn pumping mechanism / plunger drive.
Battery will not hold charge
MediumSymptoms: Short run time, low-battery early after a full charge.
Root cause: Aged battery pack.
Door / plunger / sensor mechanical wear
LowSymptoms: Set will not load, door will not latch, plunger grip poor.
Root cause: Worn door latch, plunger jaws, or anti-free-flow mechanism.

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.
- ·Occlusion pressure and flow-rate accuracy verification
- ·Battery conditioning cycle
- ·Door latch and air-in-line sensor inspection
- ·Post-drop functional check before return to service
- ·Annual PM per manufacturer schedule
Error Codes
Extracted directly from this unit's own service manual.
AIR IN LINEThe specified volume of air has been detected in the line distal to the cassette while infusing.
1 Press [SILENCE] to quiet the alarm for 1 minute. 2 Press [STOP] to clear the alarm. 3 Disconnect the patient from the pump set. 4 Press and hold [PURGE]. Note: Purge rate is 250 mL/hr. The pump purges for up to 2 minutes each time you press and hold [PURGE]. Purge volume may be limited in a Pain Management program. 5 Reconnect the pump set to the patient-access device. 6 Press [START] to begin infusion.
CHANGE BATTERIESThe pump has entered the STOP mode due to battery voltage below acceptable levels.
1 Replace both disposable batteries with fresh AA batteries and press to restart the pump; OR connect the pump to the AC mains adaptor and the pump will automatically restart. Replace both batteries as soon as possible. 2 After power-on, resume the current program. Refer to Accessing the Programming Menu in Chapter 2 Basic Operation for more information.
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: Alarm with an error message / code, delivery stopped
- Note the exact error message or code from the display.
- Look it up in the pump's technical service manual troubleshooting section.
- Run the biomed diagnostics / service utilities to exercise the named subsystem (motor / drive, a sensor, set-detection, a board).
- Follow the manual's parts-replacement procedure for that fault.
- Run the full scheduled-maintenance test set, including a flow-accuracy check, after any repair.
Symptom: Occlusion alarm / pressure fault (or a missed occlusion)
- Check the line for kinks, closed clamps and a closed roller clamp; check the patient site and cannula.
- Reload the administration set correctly, clearing all air.
- Confirm the set is an approved type for this pump.
- Run the pressure-sensor / force-sensor test in the service menu.
- Replace the set; refer the pump if the pressure sensor or pumping mechanism is indicated.
Symptom: Air-in-line alarm / free-flow or feed not delivering
- Prime the set fully and reload it; tap out micro-bubbles at the drip chamber.
- Confirm the set seats correctly against the air-in-line detector / rotor.
- Clean the ultrasonic air-detector window.
- Run the air-detector (or rotor / cassette) test in diagnostics.
- Replace a worn pumping mechanism / anti-free-flow assembly if flow accuracy or detection is out.
Symptom: Battery will not hold charge / short run time
- Fully charge, then run a battery run-down / capacity test in the service menu.
- Check the charging circuit and contacts.
- Replace the battery pack when capacity is below the service limit.
- Recalibrate the battery gauge if the pump supports it.
- Confirm run time meets spec after replacement.

Documents & Manuals
Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Hospira has received customer reports of bolus delivery failures when using the GemStar bolus cord. Possible failures may be a result of cracked or damaged bolus cords which may result in an open or short circuit of the Bolus Cord.
- RECALL
Hospira has received reports of sparking, smoking, charring and electrical shock when using the GemStar Docking Station due to fluid ingress into the docking station.
- RECALL
There is a potential for the air filter at the distal end of the set to become detached. This could result in the contamination of the sterile fluid path inside the tubing.
- RECALL
Underdelivery of infusion during clinical use at low rate settings (less than 10 mL/hour). Patient may not receive the intended amount of medication.
