Designed for bilateral or multi-site continuous regional anesthesia, the Avanos Medical P270X4D ON-Q* Elastomeric Infusion Pump provides targeted, non-opioid post-operative pain relief directly to surgical sites or peripheral nerve locations. Configured as a dual-line "pump only" set, this 270 mL elastomeric reservoir features dual fluid lines pre-calibrated to deliver a total flow rate of 4 mL/hr (split evenly at 2 mL/hr per site). Operating silently through mechanical elastomeric pressure without batteries or electronic programming, it offers clinicians a flexible, reliable base pump to connect with compatible regional block or wound infiltration catheters, supporting faster post-surgical recovery and reduced systemic opioid consumption.
