PH sensing for sensor enabled negative pressure wound monitoring and therapy apparatuses

Abstract

Embodiments of apparatuses, systems, methods for monitoring wound pH are disclosed. In some embodiments, a wound dressing includes one or more optical sensors configured to measure a change in color of a pH-sensitive adhesive that changes color in response to changes in wound exudate pH. In some embodiments, the wound dressing may further comprise hydrophilic channels that direct wound exudate toa pH-sensitive material over the optical sensors. Such dressings may also be used in combination with a negative pressure wound therapy system.

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 564,126, entitled "PH SENSING FOR SENSOR ENABLED NEGATIVE PRESSURE WOUND MONITORING AND THERAPY APPARATUSES," filed September 27, 2017; the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] Embodiments described herein relate to devices, systems, and methods for monitoring or treating wounds, eg, using dressings that sense the pH of the wound. Background technique [0004] The treatment of open or chronic wounds that are too large to close spontaneously or otherwise fail to heal by applying negative pressure to the wound site is well known in the art. Negative pressure wound therapy (NPWT) systems currently known in the art typically involve placing a fluid-impermeable or semi-permeable covering over the wound, using various means to seal the covering to the patient's tissue surrounding the wound ...
