Summer 2022
We are continuing to work on a series of projects delivering aerosols to challenging patient populations including developing a powder lung surfactant product for administration as aerosol. The image shows a surfactant powder aerosol being delivered through a model of the rabbit upper tracheobronchial airways. This aerosol was dispersed with only 15 ml of air at a flow rate of 6L/min using our novel air-jet dry powder inhaler technology.
Our intellectual property portfolio continues to expand with a patent granted for our nebulizer mixer heater technology that improves the efficiency of conventional nebulizers by reducing the aerosol droplet size. Congratulations to our co-inventors: Worth Longest, Michael Hindle, Ben Spence, Sneha Dhapare, Xiangyin Wei.
Patent title: Combination devices, systems, and methods for humidification of the airways and high efficiency delivery of pharmaceutical aerosols
The RDD 2022 meeting in Spring was a great success, with our group contributing to 8 poster and 2 podium presentations and the first time we had all gathered as a group since the beginning of the pandemic.
