Delivery, Transport, and Uptake of Inhaled Medical Gases

2014/15-2018/19 • $145,000 • PI
The global impact of chronic respiratory disease on patient health status and healthcare costs is staggering. It has been estimated by the World Health Organization’s Global Alliance against Chronic Respiratory Diseases that more than 1 billion people worldwide suffer from such diseases, which...

L'iMPacT: Low-cost Hybrid Metal 3D Printing and Machining Technology

2016/17 • $146,261 • PI,CO
Hybrid Manufacturing (HM) is a term used to describe processes which combine additive manufacturing (3D printing - AM) with subtractive (machining) processes, enabling multiple operations on a single machine. HM processes combine the benefits of each of these manufacturing techniques while...

Automated Actuator for Evaluation of Regional Droplet Deposition from Nasal Spray Devices in Nasal Airway Replicas

2016/17 • $59,716 • PI,CO
The requested funds will support a new research program to expand our department's internationally-recognized capabilities in the assessment of pharmaceutical aerosol delivery devices to include testing of devices designed to administer drugs directly to the nasal airways. Nasal drug delivery is...

High-Speed Tomographic and Three-Dimensional (3D) Imaging System

2015/16 • $143,893 • PI,CO
<p>Experimental measurements are traditionally carried out in one or two spatial dimensions although the majority of physical mechanisms are inherently three-dimensional. Measurement techniques may also lack the required acquisition frequency to capture the temporal evolution of the phenomenon....

High-Repetition Laser for Image-Based Diagnostics in Fluid Mechanics

2014/15 • $141,385 • PI,CO
The transport of a dispersed phase within fluid flow is of paramount importance in many engineering systems. In slurry pipelines in the oil sands industry, the transport of sand particles causes erosion wear, which results in downtime, maintenance costs and reliability issues. Furthermore, the...

Lung Mechanics Simulator for Testing Inhalation Drug Delivery Devices

2014/15 • $62,490 • PI,CO
These funds will assist the Principal Investigator and Co-Investigator in developing representative test platforms for evaluation of devices and patient interfaces used to administer medical gases and aerosols. Use of gases in medicine comprises specialized applications in anesthesia, critical...



A filter for mimicking regional lung deposition is provided that includes filter layers of fibrous filter material stacked coaxially and an outer ring portion encircling the fibrous filter material and securing the filter layers together. The fibrous filter material is formed for fibers having a fiber diameter, and the filter has a tunable filter efficiency. A regional lung deposition system capable of measuring constant flow or variable flow is provided that includes a throat simulation...
