Curlin Medical 4000 CMS
Curlin Medical · Model 4000 CMS
The Curlin 4000 CMS, is a multi-therapy ambulatory electronic infusion device capable of delivering continuous PCA, PCEA, subcutaneous, TPN, intermittent and variable modes. This unique, technologically advanced and innovative system continuously monitors and displays line pressure to help you detect potential catheter patency problems, such as occlusions, obstructions and pinched off catheters. The Curlin 4000 CMS™ is communication-capable (connects with PCs or PDAs); sophisticated (high resolution, user audit trail, accuracy, detailed information recording); and feature-rich (shift-totals, on-screen hourly totals, highly visible large fonts, quick-repeat and continuous back-light-on with AC power). In addition, it incorporates the unique line pressure display and productivity features of the CMS™ Software program. The 4000 CMS™ has been specifically designed to resolve the ongoing conflict between quality vs. high costs, enhancing patient safety while lowering infusion expenses. Its simplicity of operation, highlighted by menu-driven protocols with context sensitive help screens, makes the Curlin 4000 CMS™ extremely simple to use. The 4000 CMS™ has received the "CE" mark as well as many other certificates marking it for sale in the European community. The 4000 CMS™ has the ability to deliver at low rates, a flow resolution that is up to 25 times better than any other ambulatory pump on the market. The 4000 CMS™ works synergistically with a PC and/or Palm™ PDA improving the outcome, and reducing the risk of programming errors. All these features, along with its extensive information database makes the 4000 CMS™ an essential medical equipment element, capable of offering significantly improved operating performance and safety, at a substantially reduced cost. Curlin pumps give you a choice of different non-DEHP set configurations, including needleless injection sites, 0.22 and 1.2 micron filtered sets, yellow-striped epidural sets, sets with 150 ml integral fluid containers, and syringe delivery sets. All Curlin sets incorporate an active, integral-flow-stop.
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.
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.
Door / carriage sensor fault
LowSymptoms: Set not recognized, door-open error.
Root cause: Dirty or failed door microswitch.

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.
