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.

Abstract: A wound therapy system includes an instillation fluid canister configured to contain an instillation fluid, a pump fluidly coupled to the instillation fluid canister and operable to deliver the instillation fluid from the instillation fluid canister to a wound, a user interface configured to receive user input indicating one or more geometric attributes of the wound, and a controller electronically coupled to the pump and the user interface. The controller is configured to determine a volume of the wound based on the user input, determine a volume of the instillation fluid to deliver to the wound based on the volume of the wound, and operate the pump to deliver the determined volume of the instillation fluid to the wound.

Abstract: A wound therapy system includes a negative pressure circuit configured to apply negative pressure to a wound, a pump fluidly coupled to the negative pressure circuit and operable to control the negative pressure within the negative pressure circuit, a pressure sensor configured to measure the negative pressure within the negative pressure circuit or at the wound and a controller communicably coupled to the pump and the pressure sensor. The controller is configured to execute a pressure testing procedure including applying a pressure stimulus to the negative pressure circuit, observe a dynamic pressure response of the negative pressure circuit to the pressure stimulus using pressure measurements recorded by the pressure sensor, and estimate a wound volume of the wound based on the dynamic pressure response.

Abstract: A wound therapy system includes a therapy unit, a wound dressing and an optional controller. The therapy unit is configured to deliver instillation fluid to a wound site. The wound dressing is formed from a plurality of discrete, individual blocks that are selectively separable from one another along a plurality of separation-lines, allowing the wound dressing to be customized to the shape and size of the wound site. By calculating the remaining blocks that define the wound dressing following customization, the volume of the wound dressing may be determined. The controller may be configured to deliver fluid to the wound site based on this calculated volume. The controller may also optionally be used to gauge the healing of the wound site over time by monitoring the changes in volume of customized wound dressings as wound dressings are replaced during the course of treatment of the wound site.
