ARBU T U S MEDICAL

Orthopedic drill cover

To improve upon the current drill cover with a user centered approach to de sign. Our outcome will look to create an economical drill cover that is clinically dependable in regions that are developing or in crisis.


PROBLEMS Product Barrier

Constant Seam rip due to the stress caused by rotation of the drill

Defining problems of existing drill cover trhough ethnographic research

Movement Barrier Fabric bulk caused by folded back closure hinders surgeons’ movement

Manufacturing Barrier Complicated pattern leads to higher manufacturing cost.


Understanding the context: End user, Manufacture, Transportation and Culture Analysing what are the constrains and explore possible solution... soft vs. hard? reusable vs. disposable?

• The Arbutus Drill Cover has been used in over 12,000 surgeries from Kenya to Ecuador to Uganda and the Philippines

• Nurses and surgeons are semi-fluent/fluent in English and well trained before operation

• Manufactuing cost : $50CAD to $15CAD: Simplified the pattern in order to lower the cost

Fabric choice: Level 4 fluid and pathogen barrier • Linen lifetime: 80 use cycles

• Sterilize using steam autoclave

•Most less developed countries have no proper recycleing system

• Delivery of drill covers relies on volunteers with their back packs and luggage


Early concepts

Exploration of any and all possible ideas.

The Gussets

Form exploration and quick prototyping goes hand in hand...

Adding a gussets in the front and in the back to eliminate stress on the seam.

The Top

Placing the opening at the bottom and dropping the drill in from the top to eliminate the fabric bulk that hinders surgeon’s workflow.

One Gusset

Deciding on having one gusset at the front in order to minimize the number of pattern pieces and exploring possible gusset shapes.

The “T� End

Simplifying the pattern as much as possible.

The Box End

Finding difficulties seam sealing the straight angle.

The Round End

Smooth out the straight angle to make seam sealing quick and easy.


User Testing

Asked participants to assemble the drill and the drill cover according to the instructions, use drill with and without comfort to gauge accuracy and 44% comfort

An improved way of disposing coverall Protective Coverall improves the doffing process of disposable coveralls by preventing any contamination to workers in various industries and their surrounding environment while removing the garment.


1.

Understanding the user context & Industry culture through interviews, & putting ourselves in the user’s shoes

Wrist, angle, neck are the weak points because pesticide might leak through the seam

Lack of Breathability, Flexibility, Mobility Fabric bulk caused by folded back closure hinders surgeons’ movement

Seats & Floor During the Donffing process, the floor and the seating area can be contaminated

13.

There are risks of possible contamination between the garment and the worker’s skin when removing the coverall. Our goal is to eliminate this from happening.


Explore different way of doffing and different opening + testing concepts with prototypes

Deciding to integrated the hazardous waste disposable bag with the suit to reduce any potential of contamination


Current

Small zipper pulls are difficult to hadle and in finding zipper pull, users could touch their face.

Pattern

Users struggle to reach behind their back to remove the coverall.

Coverall can potentially leave harmful residue on their floor.

While the users are disposing coverall, they risk contamination.

Once the users are ready to remove the coverall, they begin to peel the hood and continue to tear away until their waist.

The users remove their gloves and sleeves in front of them instead of behind them.

An additional pouch contains a disposing bag that is placed on the floor to keep the floor sanitary.

Proposed

Instead of a zipper, adhesive tape is used to fasten the coverall closed.
