Faculty Advisor:

• Dr. Nathalie Neve

Sponsor:

Children’s Cancer Therapy Development Institute

Objective

• Primary goal:

○ Develop device safely removes embryo of a quail egg for cancer research ■ Extraction rate > one egg/ minute ■ High success rate ~90% (current: ~50%)

• Adjustable for varying egg sizes
• Should be cleaned weekly and maintained annually
• Easily operated

Results

Customer Feedbacks

• Main concern: sanitary!

○ Components withstand high temp. ~ 120 C ○ Must conform to biosafety level 2 requirements

Hirayama sterilizers hve 50

Other Issues

• Vacuum suction

○ Albumen into valves ○ Piston not providing proper suction

• Leaks in vacuum seals

○ Porous 3D printed parts

Next step

• Vacuum

○ Additional valves--change suction to compression ○ Filter or trap in case of egg breakage (e.g. syringe filters)

• Puncturing device

○ Design/ materials: carbon steel ○ Incorporate with handheld device

• Material selection

○ Suction cups: silicone (withstand high temp.) ○ Components: acrylic
