A wound therapy system includes a first sensor assembly, a second sensor assembly, and a processing circuit. The first sensor assembly is configured to be located at a wound treatment site on a patients body and to record physical characteristics representative of periwound tissue at the wound treatment site. The second sensor assembly is configured to be located at a healthy tissue site on the patients body contralateral to the wound treatment site and to record one or more physical characteristics representative of healthy tissue at the healthy tissue site. The physical characteristics representative of the healthy tissue are recorded concurrently with the physical characteristics representative of the periwound tissue. The processing circuit is configured to receive the one or more physical characteristics representative of the periwound tissue from the first sensor assembly at the wound treatment site, receive the one or more physical characteristics representative of the healthy tissue from the second sensor assembly at the healthy tissue site, and determine a healing progression of the wound based on a difference between the one or more physical characteristics representative of the periwound tissue and the one or more physical characteristics representative of the healthy tissue.

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.

Self-regulating device for modulating inflammation

A bioreactor is provided which contains cells capable of producing cytokine inhibitors in response to cytokines, in a manner regulated by the local or systemic milieu of an individual patient and predicted by mechanistic computational simulations. The bioreactor transfers the cytokine inhibitors to a patient in need of control of the inflammation process as part of a disease or condition in the patient, such as sepsis, trauma, traumatic brain injury, or wound healing. Related methods also are provided.
