Meet Tetra®

The now and future of infusion therapy

A Game Changer in
Pump Technology

Simple user interface with On/Off button, Select button, Status indicator light, and audible speaker. A 3-step infusion process, Connect PFS, Insert OPTFlow, Infuse. Get patients up and running with simple training.
No fixed or variable rate control sets, or expensive cassettes required. Reduced ancillary spend and SKU management. Lower residual volume vs mechanical infusers, means less wasted drug for patients and payors.
Five pre-programmed flow rates for specific clinical protocols. Users can select settings to achieve flow rates in IFU tables, providing infusion flexibility and supporting patient adherence.
Validated through extensive duty cycle testing for real-world use per prescribed dosing protocols, delivering reliable performance across the device's lifetime and driving long-term ROI through thousands in avoided ancillary spend. Saves 5–25 minutes of preparation time per session vs traditional mechanical pumps.
