PF-72 (Pain Free 72 hours) is a medical device
composed of Temperature Responsive Hydrogel.
It's designed to be mixed with a local anesthetic
and directly administered to the surgical site,
delivering continuous pain relief for up to 72 hours.
Continuous Pain Control for Surgical Sites using Temperature-Responsive Hydrogels mixed with Local Anesthetics
A sustained-release drug delivery medical device designed to release medication for 72 hours when mixed with Ropivacaine 0.75% (Ropivacaine Hydrochloride) and applied to the painful area after surgical procedures for prolonged postoperative pain relief.
Target Patients

How to Use PF-72 (Continued) Administration Instructions
①Using a vial adapter, draw the PF-72 mixture into a 5ml or 10ml syringe.
②Attach an 18-gauge needle to the 5ml or 10ml syringe and place it on the operating room stand.
③The PF-72 mixture in the syringe should be applied in one of two ways after the surgery is complete, but before the surgical site is closed:
-Evenly apply and inject into the surgical incision area.
-Inject and sufficiently fill the space between the sutured incision surfaces.
