USPTO Grants Patents To PARI’s Vortex Holding Chamber

PARI Respiratory Equipment announced that it was granted a US Patent for its Vortex Holding Chamber. It is a non-electrostatic, holding chamber with a one piece, dual-valve system which optimizes patient exhalation and inhalation for more efficient medication delivery with a metered dose inhaler (MDI).

While metered dose inhalers offer a quick burst of medication, there are a number of problems delivering an effective dose to patients. These include medication waste due to high-speed delivery to the back of the throat and loss of medication due to improper use. The Vortex Holding Chamber does a wonderful job of addressing these issues, in particular for young patients and for any person who has difficulty using an inhaler, by allowing patients to breathe normally while using the one piece, dual-valve system to direct medication flow and a patient’s exhalation breaths, said Dr. Welch, co-director of the Allergy and Asthma Medical Group and Research Center in San Diego, and clinical professor at the University of California, San Diego School of Medicine.

Innovations like the Vortex Holding Chamber truly enhance respiratory care by making therapies easier for patients. We are very pleased that the Vortex Holding Chamber has been granted this US patent, 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. This enhances drug delivery, minimizes drug delivered to the throat, and allows low resistance inhalation and exhalation with the device, added Geoff A. Hunziker, president of PARI Respiratory Equipment.

Vortex Holding Chamber is a innovative chamber that directs airflow during inhalation through a medication holding chamber and into the patient and during exhalation, airflow is directed out of the device while reducing medication loss. As the Vortex Holding Chamber is made of metal, it’s non-electrostatic walls do not attract medication as plastic devices do hence reduce medication loss in the holding chamber. It also features a cyclonic, inspiratory flow pattern which further enhances aerosol delivery. The Vortex Holding Chamber’s one piece, dual-valve system enhances medication delivery and reduces drug waste allowing the patient to breathe normally.
