Innovative Nebulizer System with Expiratory Filter Designed to Mitigate Healthcare Workers’ Exposure to COVID-19

 Circulaire® II High-Efficiency Drug Delivery System from Westmed optimizes medication delivery, while  reducing caregiver exposure to pathogens like the coronavirus.


In today’s unprecedented challenge to protect healthcare workers on the front lines as they battle the coronavirus pandemic, one Arizona company is providing a unique nebulizer system that is designed to optimize aerosol therapy and mitigate caregiver exposure to the contagion.

Westmed, Inc., a leader in pulmonary medication delivery, introduced the original Circulaire Aerosol Drug Delivery System in 1997. In 2008, the company modified the Circulaire II with   new features to create a quasi-closed device that significantly improved drug delivery performance, as well as the safety of the system.

One enhancement included a unique Medication Reservoir, designed to retain the excess aerosol produced during nebulization which would subsequently be inhaled by the patient during inspiration, thus providing maximum output delivery of the nebulizer. As a result, only the Circulaire II System effectively doubles the dosage of medication with every breath.

In addition to functioning as a holding chamber, conserving medication and enhancing aerosol delivery, the Reservoir also prevents room air dilution of medication to achieve the highest Fraction of Inhalable Aerosol in the industry. In fact, multiple studies confirm, the Circulaire System delivers more drug mass in less time than any other conventional nebulizer. Plus, a One-Way Valve virtually eliminates the risk of the patient re-breathing into the nebulizer, to protect the nebulizer and the Reservoir from contamination by exhaled pathogens.

Further, of particular importance today, while not a complete solution, an integral Exhalation Filter in the Circulaire II, with bacterial >99.99% and viral >99.98 efficiencies, mitigates exposure to exhaled patient droplets and medication during aerosol therapy. The Circulaire II is the only aerosol delivery system available that includes an integral Exhalation Filter as a standard feature.
