Project Goals
• To design and develop a dry-powder, singledose, disposable inhaler
• To create a prototype that is self contained,
ruggedly constructed, weather and water
proof, lightweight, small, ergonomically
designed, and actively mobile
• To be used by asthmatic individuals who
desire a temporary alternative to traditional
bulkier devices during physical activity and/or
in extreme environment settings
Personal Focus
• Researching current mouthpiece designs
• Determining the velocity and pressure during
inspiration
• Using anthropometric data for the mouth and
hands to help with prototype development
• Help in materials selection and prototype
design
• Working to determine the testing procedure
specifically the ruggedness testing protocols
Achievements To Date
• Set up weekly mentor meetings as well as use
of testing apparatus once prototype is complete
• Have industry contact at 3M to discuss any
questions or concerns
• Decided to use albuterol sulfate as the dry
powder medication
• Determined rapid prototyping options at
Swanson for prototype
• Researched anthropometric data and current
mouthpiece designs
Work To Do
• Design a prototype in Solidworks to collaborate
with group (late Jan.)
• Select materials to be used for the prototype,
possibly an ideal and practical material with
Annemarie (late Jan.)
• Contact Andy at Swanson with our final
prototype design Solidworks file (early Feb.)
• Test fluid dynamics of the drug including flow
rate and particle size with group and mentor
(Mar.)
• Develop testing protocols with group and test
ruggedness of prototype (late Mar.)
Possible Problems
• Preventing premature activation of the inhaler
• Keeping the drug airtight and at a constant
temperature
• Making the prototype portable and
comfortable
• Regulating the flow dynamics of the drug to
ensure the medication reaches the lungs
• Determining a way to dispose of the device
