Vortex Holding Chamber receives patent

MIDLOTHIAN, Va. The U.S. Patent and Trademark Office has granted a patent to a device described by its manufacturer as being designed to optimize delivery of inhaled medications.

PARI Respiratory Equipment announced last week that received the patent for its Vortex Holding Chamber, a non-electrostatic holding chamber with one piece and two valves designed to work with a metered dose inhaler.

“We are very pleased that the Vortex Holding Chamber has been granted this U.S. patient because the Vortex Holding Chamber ensures patients do not have to worry about coordinating their breaths when using a MDI to get an effective treatment,” PARI president Geoff Hunziker said in a statement. “This enhances drug delivery, minimizes drug delivered to the throat and allows low resistance inhalation and exhalation with the device.”
