OBI/OBDS

High-dose monoclonal antibodies and complex protein drugs are often too viscous for pen injectors. A wearable device capable of delivering large volumes (≥2 mL) and high-viscosity formulations (≥20 cP; 1 cP = 1 mPa·s) is known as a Large-Volume, High-Viscosity On-Body Injector — HVV OBI, designed to support controlled delivery while the device remains worn on the body.
