The Onset Mixing Pen is a high-precision dispensing device used to mix two solutions together. Once assembled, the Mixing Pen enables the precise transfer of fluid from a standard 3 mL size cartridge into a second container, such as a 1.8 mL cartridge, allowing the two solutions to be mixed.
The Onset Cartridge Connector has a sterile transfer tube that creates a fluid path between the two containers and is designed to allow the solution from the first container to be delivered via the transfer tube into the second container, where it mixes with the fluid in the second container. Simultaneously, fluid is displaced from the second container into the fluid Reservoir.
This allows a practitioner, for instance, to conveniently buffer a local anesthetic cartridge by replacing a small amount of anesthetic solution in the local anesthetic cartridge with sodium bicarbonate solution, using the 1.8mL anesthetic cartridge itself as the mixing vessel.
Onset Sodium Bicarbonate Inj., 8.4%, USP Neutralizing Additive Solution is a sterile, nonpyrogenic, solution of sodium bicarbonate (NaHCO3) in water for injection. It can be mixed with Articaine, Lidocaine, Mepivicaine or Priolocaine as a neutralizing agent immediately prior to injection.
