Case
Studies/Medical - Metered Dose Inhaler,
Spacer/Diffuser
|
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.
