Sterilization Reconsideration
•First idea was to use pipes
•Decided to use plastic bags to make
cleaning easier
•Operator can just change bags and wipe
down the machine

Continued Research
•How many sponges typically used
during surgery (large counts make
device necessary)
•Number of operations per year
•Average number of sponges per
operation
Future Work
• Contact Manufacturers about
sensor counters
• Determine total cost resulting
from gossypiboma
