2. Analysis: Problem Statement
We need a more efficient and effective way to treat nosebleeds, especially under a time constrain.
1. Wrestling meets—can expect at least one nosebleed every hour—up to 25 in one tournament
2. Current treatments—doesn’t fit right, hard to put in and remove, either very cheap or very expensive
Current most popular material is dental roll—but it was made for the mouth, not the nose. Price ranges of products which ARE designed for the nose start at $3
Need a product which is designed specifically for the nose—yet affordable

3. Analysis: Performance Criteria
Design Criteria:
Reasonable price
Absorbent material
Stops bleeding quickly
Easy removal and insertion
Fits well
Want something cheaper than $3 (preferrably >$1)
must absorb well—probably cotton material, woven well so no strays or breaks
must FIT well (variety of sizes, vs current one-size-fits-all)
tab or loop so easy to remove (clip will not work as it can be knocked out)

4. Analysis: Primary Objective
Project Goal: Develop inexpensive, effective nosebleed plug to be used in athletics, specifically high school wrestling

5. Hypothesis: Solution Description

6. Hypothesis: Goals Quick and Easy Simple instructions Tapered
Stripes of Vasoconstrictor

7. Hypothesis: Factors Benefits: Cost Effective Variety of sizes
Anatomical fit
Easy insertion and removal

8. Hypothesis: Factors (cont.)
What will affect costs:
Manufacturers (US or overseas)
Packaging
Brand name or generic
FDA testing

9. Hypothesis: Performance Metrics
Average Nostril Size
Width: 1.3 cm
Depth: 1.5 cm

11. Validation: completed
Analyze preliminary performance based on parts
Tampon material does absorb well
Size is better fit than cotton rolls
Cheaper than QR or rhinorocket

12. Future Validation We haven’t completed synthesis phase
Need manufacturer
Will show ATCs, ENTs, and athletes our prototypes and sketches
