Pulmonary Deposition of Ultrasound Rock Salt Aerosol Inhalation Therapy

Sponsor: Jingen Xia

Summary

In the in vitro modeling phase, the investigators plan to use a realistic human upper respiratory tract model and an asymmetric ideal bronchial tree model. By combining 3D printing experiments with CFD simulations, the investigators will investigate the respiratory tract deposition rate and distribution of micro - moist particles in ultrasound rock salt aerosol inhalation therapy. This will be compared with a small - volume nebulizer to verify the effectiveness of ultrasound rock salt aerosol inhalation therapy and lay the foundation for further research on the application of this inhalation technique to other drug formulations. In the clinical phase, the investigators plan to have subjects inhale radioactive aerosols and use PET/CT imaging technology to assess the deposition rate of aerosol particles in the lungs. By quantitatively analyzing the images, the investigators will study their distribution characteristics in real human bodies to verify the accuracy of the in vitro models and the potential for clinical application.
