Idaho Patent of the Month – June 2022

Percussionaire Corp. has dedicated their practice to advancing the world of respiratory care in an effort to save lives. This mission has driven their past 30 years of innovation as they first designed then enhanced their Flow Ventilation devices. This innovation is reflected in their recently awarded patent which encapsulates the percussive ventilation breathing head attachment. 

A nebulizer is a type of breathing machine that lets a user inhale medicated vapors. Often prescribed for coughs and respiratory illnesses, these machines are especially helpful for those who may have some difficulty reliably using handheld inhalers – infants, toddlers, or people with various conditions or disabilities.

This device can attach to a nebulizer, assisting in the delivery of a flow of pulsatile gas to the patient. The attachment point has a unique seal which uses an audible or tactile response to indicate a proper attachment. For instance, a turn-and-click, one-way attachment is a nearly foolproof sealing mechanism. The click lets the user know when the seal is formed.

The attachment is designed with a mouthpiece, an interior passageway, and an injector shuttle. The shuttle is moved as the pulsatile gas moves through. A jet nozzle pulls the nebulized gas from the nebulizer. This design helps the user achieve intermittent percussive ventilation. During inhalation, the patient pulls the nebulized gas into his lungs through the attached head. The pulsatile gas flow ensures additional gas is delivered to the patient when inhaled. During exhalation, a pressure sensitive system in the breathing head allows exhalation through an outlet tube.

This pulsatile flow bathes the alveoli (where the lungs and the blood exchange oxygen and carbon dioxide during breathing) with fresh oxygenated air while washing out CO2 secretions. Over time, the Pulsatile Flow gently persuades distal airways and collapsed alveoli to open which keeps lung supported and respiring while atelectasis, infection, inflammation, and injury can heal.
