Some embodiments are illustrative of an apparatus or system for delivering negative-pressure and/or therapeutic solution of fluids to a tissue site, which can be used in conjunction with sensing properties of fluids extracted from a tissue site and/or instilled at a tissue site. For example, an apparatus includes a dressing interface or connector that includes a pH sensor, a humidity sensor, a temperature sensor and/or a pressure sensor embodied on a single pad within the connector and proximate the tissue site to provide data indicative of acidity, humidity, temperature and pressure. Such apparatus includes algorithms for processing such data for detecting leakage and blockage as well as providing information relating to the progression of healing of wounds at the tissue site.

Abstract: A wound debridement system includes a wound dressing having an active layer and a wound interface layer. The active layer is formed from one or more transmission layers that are arranged about a central post. Activation of the transmission layers is configured to cause the movement of the wound interface layer relative to a tissue site to which the wound dressing is applied. A drive unit is operably attached to the central post. The drive unit is configured to generate and transfer a vibrational energy and/or a rotational movement to the transmission layer(s) via the central post. The resultant vibration and/or rotation of the transmission layer(s) is imparted onto the wound interface layer, thereby effectuating the desired movement of the wound interface layer relative to the tissue site, which allows for the debridement of debris that may be located at the tissue site.
