Machine Proximate Nebulizer Respiratory Therapy System
Summary
The USPTO has published patent application US20260097172A1 for a machine proximate nebulizer respiratory therapy system. The application, filed on June 11, 2025, covers a nebulizer system with a cylindrical mixing chamber, impacting cap, and recirculation tube for delivering aerosolized medicaments in respiratory therapy. The invention aims to improve aerosol delivery efficiency by entraining aerosol into breathing gas and recirculating rain-out droplets.
What changed
The USPTO published a patent application for a machine proximate nebulizer respiratory therapy system. The system includes a nebulizer for aerosolizing medicaments, a cylindrical mixing chamber with inlet, outlet, aerosol, and drainage ports, an impacting cap to coalesce aerosol droplets, and a recirculation tube to return rain-out to the nebulizer. The mixing chamber entrains aerosol into breathing gas for delivery to patients.
Affected parties including medical device manufacturers and healthcare technology developers should monitor this application for potential impact on respiratory therapy device development. The published claims, once granted, could affect freedom to operate in the nebulizer and respiratory therapy device space.
What to do next
- Monitor for patent grant or office action updates
- Review claims for potential infringement risks if developing similar respiratory devices

Abstract
Systems and methods for providing respiratory therapy are disclosed. The system includes a nebulizer operable to aerosolize a medicament, a cylindrical mixing chamber, an impacting cap and a recirculation tube. The mixing chamber has an inlet port, an outlet port, an aerosol port in fluid communication with the nebulizer, and a drainage port. The inlet port receives a flow of breathing gas. The mixing chamber receives the aerosol via the aerosol port, entrains aerosol into the flow of breathing gas, and delivers the breathing gas entrained with aerosol to the outlet port. The impacting cap receives and coalesces a portion of the aerosol into droplets within the space defined by the mixing chamber and the impacting cap. The mixing chamber is also configured to direct rain-out resulting from the droplets to the drainage port. The system also includes a recirculation tube to return the rain-out to the nebulizer.
