Technology improves patient compliance and care
Wound Solutions invited PDD to help design and prototype the VS-01; a body-worn device used to reduce the healing time for lower leg venous ulcers. This product delivers micro-currents from two electrodes placed on either side of the hard-to-treat wound to promote oxygenation and capillary density.
The device, worn under compression bandages, would also alert patients discreetly when exercising the leg will promote healing and would record such patient activity so that medical practitioners can analyse it and adjust patient activity targets as required.
With deep understanding of patient needs, PDD designers and human factors specialists overcame the significant challenge to develop a one-size-fits-all solution that can accommodate differing leg sizes comfortably and respond to varied sensitivities found between patients. Good wearability was assured by developing a compact solution which encases a vibrating motor for alerting patients, a pressure sensor and electronic modules.
The medical practitioner needs were addressed by ensuring the electronic interface design and device application method was simple and intuitive.
Following successful demonstration of efficacy through clinical trials, PDD helped Wound Solutions gain a platform to deliver an expanding range of innovative products to the wound treatment market.
