The RAS provides caregivers with a low cost easy to use objective tool to assess the health status of the skin. It quantitatively measures the blanch response and erythema, the primary diagnostic cues of an early stage PU. It can detect these cues whether or not they are visible due to the patient’s skin color and independent of the skill of the caregiver. It also quantitatively measures complimentary properties of the skin such as temperature and skin firmness. The RAS is used with a high volume consumable, a disposable skirt, that maintains sterility between patients. The RAS also includes a mobile app for patient data tracking that allows clinicians to monitor the health of the skin to personalize care. The RAS will also integrate with electronic health records systems.
