Cuffs & Accessories
Why is proper cuff sizing important?
Are Delfi cuffs compatible with other systems?
What cuffs are available?
All are available in single-port and dual-port configurations.
Do you offer disposable and reusable cuffs?
Yes. Delfi offers both reusable and sterile single-use cuffs, as well as a hybrid option:
- Reusable cuffs: Easi-Fit, Petite-Fit, Vari-Fit.
- Sterile single-use cuffs: Easi-Fit, Pedi-Fit, Vari-Fit.
- Hybrid cuff (Adaptive): Supplied sterile for initial use and may be reused up to five times following appropriate cleaning between uses.
Why would I use a Matching Limb Protection Sleeve (MLPS)?
Why use an MLPS instead of generic padding?
How should cuffs be cleaned between uses?
Products labeled as single-use must be disposed of after use.
Instructions are included with each product and are available at: delfimedical.com/ifu
Why does cuff shape matter in surgical tourniquet use?
Why are Delfi Easi-fit and Vari-fit cuffs contour shaped?
How are Delfi Pediatric Cuffs different from shorter adult cuffs?
Delfi Pediatric Cuffs are specifically designed with appropriate width and application ranges for pediatric limbs. This helps maintain proper cuff-width-to-limb-size relationships, which are associated with achieving occlusion at lower pressures.
Why is cuff width important?
Wider cuffs generally require lower pressure to achieve arterial occlusion compared to narrower cuffs. Clinical guidance recommends selecting cuff width and length based on limb size and circumference to support safe and effective use.
Why is rapid cuff inflation important?
PTSii Tourniquet System
Where can I find the Instructions for Use (IFU) for the PTSii?
What is the pressure range of the PTSii?
For specific applications, an extended pressure range of up to 600 mmHg may be enabled following user confirmation of a warning.
How accurate is the pressure measurement?
Is the PTSii available in a dual-channel configuration?
Yes. The PTSii can be configured as a twin system, where each unit operates independently. This supports use during simultaneous bilateral limb procedures and IVRA (Bier Block).
The twin configuration also allows the units to be separated and used independently in different operating rooms when needed.
How quickly does the cuff inflate?
The PTSii inflates a 34-inch cuff on a 30-inch thigh to 350 mmHg in less than 5 seconds.
How is the PTSii powered?
How long does the battery take to charge?
What safety features are included?
The PTSii incorporates multiple safety mechanisms, including:
- Automatic system self-checks
- Continuous pressure regulation
- Integrated cuff leak detection
- Continuous self-monitoring
- Positive Locking Connector (PLC)
How do I calibrate the PTSii?
The PTSii performs automatic self-calibration. Annual calibration is recommended as part of routine maintenance or following any unscheduled service.
Delfi offers a dedicated calibration service. Contact: service@delfimedical.com
How easy is the PTSii to use in the operating room?
Can I send my Delfi PTSii instrument to you for service or calibration?
Yes, you can. Send a message with your information as a Service Request here.
