Clinical Problem
Clinical Problem
Sharp edges from aluminum peel
Sharp edges from ampoule fracture

Clinical Problem• CDC estimates that over 385,000 sharps-related injuries are
reported each year, many more go unreported
• Following the Needlestick Safety and Prevention Act of 2000,
sharps-related injuries in surgical settings increased by 6.5%
(2001-2006)
Design NeedsA solution that is:
1) Safe for both patient and medical personnel
a. No sharp edges created or exposed
b. No glass particles entering drug solution
2) Effective for delivery of drug solution
a. Efficient in opening drug container
b. Dual-functionality
3) Demonstrate adaption to the clinical setting
a. Minimal training required to use
b. Automated

Two Directions
Anesthesia Container Redesign Device for Opening Container
• Dr. Gow’s original idea
• Clinical Dogma
• Lack of specific
knowledge involving
manufacturing and
implementation
• Complementary to
containers used today
• Versatile
• Capable of improving safety
and efficacy

Our SolutionVials
● Characterized by a thick foil, tamper-evident seal that can
lacerate any personnel handling the device
Ampoules
● Characterized by a serrated glass edge and broken glass shards
Solution: Complementary device
● A lightweight, small, portable, and versatile device which can
address the issues found in both containers.
● Capable of removing the foil from a vial and scoring and
removing the glass head from an ampoule
Our Prototype

Our Prototype
● Place on top of vial –
ensure blade punctures foil
● Spin to remove foil via
cutting mechanism
● Removes danger of
laceration
Our Prototype
● Blade is currently ~0.1cm too short
● Tops of vials are generally universal

10
Our Prototype● Place neck of ampoule
inside of device – secure by
pressing down with thumb
● Score around the neck with
adjustable pressure
● Safely removes the head of
the ampoule

Prototype SummaryVial Opener
● Simple, easy-to-use
● Universal application
Ampoule Opener
● Manual application of scoring pressure
● Ambidextrous
● Universal through use of adjustable trigger
Materials
● Cutting mechanism still under investigation (e.g. diamond cutter)
● Material used for device also being investigated
Moving Forward• Print our first 3D model
• Learn how to integrate materials into our model (blades, springs,
etc.)
• Test our device on newly ordered vials and ampoules
• Great feedback from Dr. Neils and Molly Blank• Assign group members to improve distinct pieces of our
device.• Don’t get too close minded. Leave room for improvement in
future iterations.

Questions We Are Facing
• Single-use versus multi-use?
• What materials could we use for different
components of the device?
• How could we remove human error in our
device?
• Should we incorporate electronics meant to
automate our design? What will this mean for
reusability?
Summary of Milestones
• Given our problem and a blank slate
• Brainstormed many ideas. Some realistic, some not.
• Settled on a preferred design
• Have gone through several iterations already
