U.S., March 25 -- ClinicalTrials.gov registry received information related to the study (NCT06891274) titled 'Pulmonary Deposition of Ultrasound Rock Salt Aerosol Inhalation Therapy' on March 12.
Brief 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 foundatio...
