This project aims to untangle the fundamental principles that govern the fluid mechanics and particulate interactions in a novel concept chip-based micro-zero-net-mass-flux (micro-ZNMF) jet-assisted dry powder inhaler (DPI). Respiratory diseases affect 6.2 million Australians. The treatment of these diseases is hampered by the poor efficiency of current delivery systems, with conventional DPI devices exhibiting sub-optimum performance, delivering typically less than 20% of the loaded dose to the target site, the lungs. The new fundamental knowledge resulting from this research will enable the engineering of a high-efficiency groundbreaking DPI, with the potential to be fully adaptive user-specific benefiting millions of Australians.

该项目旨在阐明基于新型概念芯片的微零净质量通量 (micro-ZNMF) 喷射辅助干粉吸入器 (DPI) 中控制流体力学和颗粒相互作用的基本原理。呼吸系统疾病影响着 620 万澳大利亚人。这些疾病的治疗受到当前输送系统效率低下的阻碍，传统的 DPI 设备表现出次优性能，通常只能将不到 20% 的负载剂量输送到目标部位（肺部）。这项研究产生的新基础知识将使高效突破性 DPI 的设计成为可能，并有可能完全适应特定于用户的需求，使数百万澳大利亚人受益。
