Delfi · Model PTS
Integrated Tourniquet Cuff Testing-for testing the integrity of the tourniquet cuff with tubing and connectors before or after surgery, as recommended in current AORN standards and recommended practices. Rapid Cuff Inflation & Deflation-Inflates a typical 34″ thigh cuff in less than 5 seconds Extended Pressure Interlock- A safety interlock limits normal maximum pressure to 475mmHg, and allows staff to select an extended pressure of up to 600 mmHg if required for patients with special needs Long Battery Life-Up to 15 hours of operation with tested cuffs Connectivity Allows easy integration with OR information networks Advanced Leak Detection During Surgery-Monitors the tourniquet cuff, tubing and connectors for air leaks during surgery, and safely alerts staff to hazards or follow-up actions required Color Display & Intuitive User Interface-For clearly visible key tourniquet parameters and simplified operator training Printer{Optional} Provides a record of events including tourniquet time and pressure levels, for easy inclusion in patient records.
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.
Will not reach or hold set cuff pressure
HighSymptoms: Pressure droops during a case, will not inflate to setpoint, leak alarm.
Root cause: Internal pump / compressor wear, a solenoid-valve fault, or a leak in the tubing / cuff / connectors.
Pressure inaccuracy / calibration drift
HighSymptoms: Displayed pressure differs from an independent gauge - patient-safety critical.
Root cause: Pressure-transducer drift or a calibration fault.
Dual-channel / bilateral fault
MediumSymptoms: One channel will not regulate independently, cross-talk between channels.
Root cause: Channel solenoid / transducer or a manifold fault.
Alarm / timer fault
MediumSymptoms: Inflation-time alarm not sounding, timer wrong.
Root cause: Alarm / timer board fault - a safety function.
Tubing / connector / cuff fault
MediumSymptoms: Leak at the connector, cuff will not hold.
Root cause: Worn tubing, connectors, or a damaged cuff.

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: Will not hold set pressure
- Fit known-good tubing and a known-good cuff.
- Occlude the outlet and confirm the pump holds pressure.
- Check the solenoid / regulator valve.
- Verify displayed pressure against a calibrated reference gauge across the range.
- Rebuild / replace the pump, valve or transducer as isolated.
Symptom: Pressure reads inaccurately
- Tee in a calibrated gauge and compare at several set pressures.
- Run the calibration procedure per the service manual.
- Confirm both channels on a dual unit.
- Confirm the inflation-time alarm sounds.
- Do not use the tourniquet clinically until pressure accuracy is confirmed.
