Title: Innovations of Jeffrey Chen in Dry Powder Inhaler Technology
Introduction
Jeffrey Chen is a notable inventor based in San Diego, CA, with a remarkable portfolio of seven patents. His work primarily focuses on advancements in inhalation technology, particularly in the development of dry powder inhalers.
Latest Patents
One of Jeffrey Chen's latest patents is a dry powder inhaler that features a dispersion chamber containing beads. This innovative design allows a dose of dry powder to be released into the chamber or into an inlet that tangentially joins the chamber. As the patient inhales through a nosepiece or mouthpiece, air circulates within the dispersion chamber, driving the beads. The beads roll, bounce, and collide with drug particles on the chamber surfaces or on the beads themselves. This process effectively separates smaller active drug particles from larger carrier particles, creating a powder aerosol that the patient can inhale. The lightweight nature of the beads enables rapid acceleration and movement, even with minimal inspiration. Additionally, the design reduces flow resistance, allowing for greater airflow and powder dispersion without requiring increased effort from the patient.
