ObjectiveObjective
“Develop a better, less expensive method than the current KCI wound bag system to assist in wound healing. The method may involve suction techniques or other methods to assist in the partial surface closure of wounds.”

Goals of Topical Wound Treatment
Goals of Topical Wound Treatment
Provide adequate circulation/oxygenation Remove necrotic (dead) tissue Eliminate large amounts of exudate Eradicate clinical infection Obliterate dead spaces or voids Maintain a clean, moist wound surface

Current Healing TechniqueCurrent Healing Technique Vacuum Assisted Closure (V.A.C.) Therapy
Promote granulation tissue formation through the promotion of wound healing.
Uniformly draw wounds closed by applying controlled, localized negativepressure.
Remove interstitial fluid allowing tissue decompression.
Remove infectious materials. Provide a closed, moist wound healing environment. Treats Chronic open wounds, Diabetic ulcers,
Pressure ulcers, Acute and traumatic wounds, Flaps and grafts, Dehisced Wounds, and Partial Thickness Burn

Standard V.A.C. Operating Procedure
Standard V.A.C. Operating Procedure
Foam is placed over or in wound A large piece of transparent tape/ dressing is placed over
the wound and surrounding healthy tissue Catheter tubing connects vacuum source and dressing Negative pressure of vacuum draws excess fluid that may
hinder wound healing into a canister Dressing changed every 48 hours

Disadvantages of Current Devices
Disadvantages of Current Devices
Adhesive Polyvinyl Dressing/Seal damages fragile skin when removed
Foam/ Dressing has caused irritation Costs:
Daily costs of V.A.C. exceeds that of the traditional, twice-a-day dressing changes with a topical antimicrobial with regard to dressing and nursing costs ($282/day versus $75/day).
However, V.A.C. decreases costs when considering the added costs of increased operative time for complex reconstructions as well as for the treatment of associated complications.
Why not decrease both?

Ethics Ethics
Meets safety requirements and health standards
Easy to operate =>minimal training required
Reduce healing time => hospital stay duration minimized
Easy to fix => minimize difficulty in repair and customer service

Market AnalysisMarket Analysis
We intend to investigate material/ production costs of current products
Our design should minimize production costs while producing a quality product
Introduce competition into the market
