Objective:

Design an efficient, low-cost, FDA approved, inhalation therapy drug delivery device for volume production that:

• Outperforms competitive devices.
• Reduces drug plate-out due to static charge.
• Improves drug dispersion in the air steam.
• Is usable by a broad range of patients.

Engineering Tools and Prototype Fabrication

• Acquire and evaluate rigid and elastomeric parts using stereolithography.
• Develop Materials Selection Criteria.
• Anodized aluminum alloy to meet FDA toxicity requirements.
• Chemical resistant, steam resistant, transparent thermoplastic, thermoset elastometer, adhesive for metal/plastic bonded joint and adhesive-backed label materials.

Design Features:

• Employs an ATI designed, one piece two-way valve.
• Product design uses a snap-together assembly for easy cleaning.
• Mates with metered dose inhalers and accessories.
• Impact resistant.
• Can be sterilized in a steam autoclave.

Manufacturing Support:

• Identify metal part supplier.
• Identify molding supplier for thermoplastic and thermoset parts.
• Exported digital 3-D files for tool path and tool build.
• Evaluated steam resistance for thermoplastic materials, adhesives, and labels.
• Design and support fabrication of test fixtures.
