Hospira Gemstar single
Hospira · Model Gemstar single
The GemStar line of products offers three models for I.V., arterial or epidural infusion for I.V. fluid, medications nutritional fluids and blood/blood products. These versatile infusers are compact and portable and can be used in the hospital, home care environments or ambulatory applications. The GemStar infusion pumps provide single channel administration of up to seven different therapies. These rugged units are built on lightweight aluminum frames protected with color-coded bumpers making them durable and easily recognized.
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
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Occlusion / downstream blockage
HighSymptoms: Occlusion alarm, no flow, upstream pressure high.
Root cause: Kinked set, clamped line, patient vein issue.
Air-in-line detection
MediumSymptoms: Air-in-line alarm, infusion paused.
Root cause: Air in set, improperly primed tubing.
Free-flow (failure of anti-free-flow)
HighSymptoms: Uncontrolled flow when door open.
Root cause: Worn roller or failed free-flow valve.
Motor / drive failure
MediumSymptoms: Stalled infusion, inaccurate rate.
Root cause: Peristaltic motor or encoder wear.

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
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Occlusion / downstream blockage
- Confirm the presentation - typically occlusion alarm, no flow, upstream pressure high - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: kinked set, clamped line, patient vein issue.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the iV administration set per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: Air-in-line detection
- Confirm the presentation - typically air-in-line alarm, infusion paused - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: air in set, improperly primed tubing.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the peristaltic roller / pump mechanism per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
During infusions of 2.0 mL/hr the motor assembly may rotate backwards capturing additional medication resulting in over-infusion.
- RECALL
Battery level lower then 2.4 volts results in corrupt history log and loss of data for preview therapy's parameters and causes an 11/004 error resulting in the pump not being able to be used.
- RECALL
Pump shutting off during use without warning.
- RECALL
The proximal and distal pressure sensor calibration can drift resulting in the pump failing the Proximal or Distal Occlusion Operational Test, as described in the GemStar Technical Service Manual, or reporting one of the following errors during device setup or infusion: 1) Cassette Check - D; 2) Cassette Check - P; 3) Proximal Occlusion; 4) Distal Occlusion; 5) Pressure Calibration Error; 6) Bad Pressure Sensor Event; 7) Bad Pressure State; 8) Distal Pressure is Out of Range; 9) Proximal Sensor is Out of Range. A pump with this issue may, instead of reporting an error, not detected occlusions or issue false occlusion alarms, which will stop the infusion and invoke visual and audible warnings to the user.
- RECALL
Reports of difficulty in adjusting the flow rate, which could result in flow rate variances.
