Smiths Medical CADD-Legacy Plus 6500
Smiths Medical · Model CADD-Legacy Plus 6500
• Easy to Read Display - Easy to read and understand display screen provides information for programming adjustments and troubleshooting • Cassette Detection - Cassette detection sensor is designed to detect cassette attachment • Occlusion Detection - Upstream and downstream occlusion sensors are designed to alert the patient and clinician if interruption of fluid delivery occurs • Air-in-Line Detection - Air-in-line detector with Off, High- and Low-sensitivity settings is designed to alert the patient and clinician if air is present in the administration set tubing • ON/OFF Key - ON/OFF key allows pump to be placed in low-power state and is designed to save battery life • Event Memory - The last 1,000 events in the pump's history can be downloaded either directly or remotely (using a modem) to a PC using the CADD-DIPLOMAT® PC Communications System • Reliability - CADD® pump reliability and durability can mean less down time and fewer interruptions to therapy
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.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Smiths Medical has identified that the securement flange of specific lots of the Bivona Neonatal/Pediatric and Adult Tracheostomy products may tear because of a manufacturing defect.
- RECALL
Reported pressure shifts and incorrect pressure readings in LogiCal Closed Blood Sampling System sets.
- RECALL
Certain lots of the Model 306701 ProtectIV Plus Safety IV Catheter may exhibit damage on the safety mechanism guard.
- RECALL
Certain CADD Legacy 1, Ambulatory Infusion Pumps, may contain non-matching serial numbers. The label attached to the back of the pump may list a serial number that does not match the correct serial number programmed into the software of the pump.
- RECALL
Difficulty disconnecting accessories from the Bivona Uncuffed Neonatal, Pediatric and Flextend Tracheostomy Tubes TR3 connector, which may result in a delay in initiating therapy or patient discomfort. If excessive force is used to detach the accessory, this may result in decannulation of the tube which could result in serious injury or death; especially if no replacement tracheostomy tube is imm
- RECALL
The CADD-Legacy 1 Model 6400 Ambulatory Infusion Pump (Serial Number 370969) was shipped without documentation that the required accuracy testing had been performed during the manufacturing process. If the subject infusion pump did not go through the accuracy testing, and if it does not meet accuracy specifications, there is a potential for over or under-delivery.
- RECALL
Smiths Medical became aware that product returned to them under recall # Z-0800-06/ Z-0807-06 was inadvertently distributed to consignees after the recall was initiated 03/29/2006. The product was originally recalled because Locator Wand covers, which are supplied on the outside of PORT-A-CATH and P.A.S. PORT sterile trays, may have an insufficient seal and product sterility could be compromised.
- RECALL
One lot of Locator-Wand Cover sterile pouches may have an insufficient seal and product sterility could be compromised. The Locator-Wand Cover is supplied with the PORT-A-CATH II AND P.A.S. PORT systems. The packaged Wand-Cover is placed on the outside of the PORT-A-CATH II AND P.A.S. PORT tray.
