Iterative design and testing of a hand-held, non-contact wound measurement device
Abstract A variety of wound measurement techniques are available to clinicians. Options range from relatively simple and inexpensive to complex, expensive devices. An iterative design approach was used to evaluate and improve performance and clinical utility of a new wound measurement device (WMD)....

An iterative design approach was used to evaluate and improve performance and clinical utility of a new wound measurement device (WMD). The design was based upon a commercially available Smartphone. Accuracy was assessed using bench testing and reliability of area measurements was determined using multiple evaluators. Clinical utility was investigated by deploying the WMD during wound rounds in a rehabilitation hospital. Accuracy testing revealed an average error |
