Engineered for dual-site continuous regional anesthesia and targeted post-operative pain management, the Avanos Medical CB6007 ON-Q* Pain Relief System with C-Bloc* Dual Select-A-Flow* Variable Rate Controllers delivers controlled, non-opioid regional analgesia simultaneously to two surgical sites or peripheral nerve locations. Featuring a high-capacity 600 mL elastomeric reservoir, this battery-free infusion pump utilizes elastomeric membrane pressure to deliver local anesthetics silently and continuously. The dual Select-A-Flow* controllers allow clinicians to independently titrate flow rates on each infusion lead between 1 mL/hr and 7 mL/hr (up to 14 mL/hr combined), tailoring pain relief to complex bilateral or multi-site surgical recoveries.
