Overview • Problem statement • Background information • Design objectives & criteria • Product design specifications • Product design • Design alternative • Conclusion & future plans
Problem Statement Currently there is no device that allows field researchers to extract blood samples from free-ranging large cetaceans. Developing a tool where blood can safely be taken from whales in the wild would mark a breakthrough in current technology and allow for subsequent studies to focus on critical physiological indices necessary for maintaining the general health of cetacean populations.
Background Information • Obtaining blood: Humpback whale anatomy
Similar Field Work • Biopsy darting
Objectives & Criteria • Capable of extracting 1 cc of blood • Capable of penetrating 4 inches of skin • Capable to be shot from crossbow • Extracted blood should not mix with sea water
Objectives & Criteria • Cheap to produce • Should not harm whale • Easy to retract • Light weight
Key PDS • Shape: cylindrical • Size: at most 12 inches • Safety: releases after extracting blood • Accuracy: hits vein (or artery) in tail fluke
Product Design • 8 inch needle • Stopper • Outer Cylinder • Fins for stability 5. Penetrable material 6. Vacuum cylinder 7. Site for retracting
Design Alternative • Penetrable material • 10 inch needle 3. Cylinder 4. Vacuum
Design Alternative (Cont.) • Pressure sensitive chemicals • Expandable balloon
Conclusion The proposed design takes the key product design specifications into consideration, and fulfills needs of our client.
Future Plans • Build an operational prototype • Design dart for use with smaller crossbow • Test prototype
