This project was part of the Fall 2013/Winter 2014 NUvention: Medical course.

Negative Pressure Wound Therapy uses a vacuum source over the area of deep, infection prone wounds in order to promote granulation of the tissue and remove unwanted exudating fluid, increasing the healing time as well as reducing the risk of infection. Many of the systems used today are large units that are plugged into the wall which can be restrictive and cumbersome. Some portable solutions are becoming adopted for more mobile patients, however these are still very expensive preventing their use in many cases. ​

Solution Detail of WoundAid prototype

WoundAid provides this highly effective negative pressure wound therapy at a significantly lower cost, while allowing portability and silent operation to be as non-intrusive as possible in a patient’s lifestyle. The device does not use any power source or have any moving parts to maintain simplicity and a low cost.

Development Process

The team began by needs finding through shadowing and secondary research to identify a gap in the market. The wound market gap was initially identified between very low cost wound care, such as a bandaid or dressing, and very high cost, stationary Negative Pressure Wound Vac systems. Through interviewing patient’s families and wound care clinicians, the primary value propositions were established around low cost and portability. The team prototyped and iterated many different concepts, each with different mechanisms for creating a vacuum and indicating pressure level. The initial target market was adjusted throughout the process of interviewing a number of stakeholders to focus in on the most viable business plan.
Iterations continued to align with the market opportunity and patient population and needs, and a final business model and prototype was presented to a panel of industry leaders and potential investors for further feedback and development.
