Clinical Problem

Clinical Problem

Sharp edges from aluminum peel

Sharp edges from ampoule fracture

3/8/2016

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

9

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
