Project Goals

• To design and develop a dry-powder, single-dose,
  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

4
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

5
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.)

6
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
