How it Works 

ON-Q C-bloc is a continuous peripheral nerve block system that slowly infuses local anesthetic near a nerve for effective pain relief. A simple and reliable system, ON-Q C-bloc is an optimal alternative to electronic pumps.

• Quicker return to normal, including ambulation, body functions, and full range of motion
• Decreased complications associated with narcotics
• Significantly better pain relief than narcotics alone
• Significantly less need for narcotics following surgery
• Reduced or eliminated narcotic-related side effects and complications
• More comfortable recovery
• Constant pain relief, so pain doesn’t “break through” as it sometimes does with narcotics

ON-Q C-bloc with ONDEMAND™
ONDEMAND has an added feature that allows patients the option for 5 ml of additional medication for effective post-operative pain relief. It is available with a 30 or 60 minute refill time, to effectively manage breakthrough pain.

• Allows patients to have both continuous and on demand pain relief
• A unique and ergonomic patient-controlled button
• Requires less clinical intervention

ON-Q C-bloc with Select-A-Flow
Select-A-Flow allows you to adjust the flow rate according to your patients’ individual pain relief requirements. The Select-A-Flow variable rate controller is available in two versions. Select-A-Flow variable rate controller offers titration for dosing flexibility

• Rate-changing key clicks into place and may be removed for tamper resistance
• Cover can be secured for tamper evidence
• Easy viewing of rate setting
• Available in a convenient high volume size
• (600 ml vol, max 750 ml vol)
