CORPAK Medsystems Polar Enteral Feeding Bags & Set
CORPAK Medsystems · Model Polar Enteral Feeding Bags & Set
Unlike PVC, two-ply EVA/Nylon Polar Bags won’t leach plasticizers into enteral formula. Safe for the environment as well. Inside of cap is recessed to minimize touch contamination. Connector strap keeps cap away from funnel during filling to prevent touch contamination. Pump tubing segment is securely glued to the connector to prevent tubes from blowing off when irrigating or adding meds. Anti-IV stepped connectors. Two-ply EVA/Nylon construction eliminates pin holes, adds strength. EVA/Nylon bags are stronger than PVC, won’t stretch like PVC. Safety-lock cap provides an airtight seal. Widest opening of any bag makes spill-free filling easier. Bag funnel doubles as a handle. Crystal clear EVA plastic allows you to see meniscus and condition of formula. Hanger centers the bag and eliminates sagging. Cap is easy to open and close, even by home 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.
Feed not delivering / rotor-fitting fault
MediumSymptoms: No or inaccurate feed delivery, set not detected, cassette / rotor error.
Root cause: Worn rotor / pump mechanism or a mis-loaded feeding set.
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
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: Error message or code
- Note the exact error message / code.
- Look it up in the pump's technical service manual troubleshooting section.
- Use the biomed diagnostics / utilities to test the affected subsystem.
- Follow the manual's parts-replacement procedure.
- Run the scheduled-maintenance test set (including flow accuracy) after any repair.
Symptom: Occlusion or delivery problem
- Check the line for kinks, clamps and a closed roller clamp; check the patient site.
- Reload the set correctly, clearing all air.
- Confirm an approved set for this pump.
- Run the pressure / air-detector (or rotor) test in diagnostics.
- Replace the set; refer the pump if a sensor / mechanism fault is indicated.
