  • Publication number: 20230190519
    Abstract: A medical pad for exchanging thermal energy between a targeted temperature management (TTM) fluid and a patient. The medical pad includes a fluid containing layer configured for circulation of a TTM fluid therein. The pad may further include a bistable stiffening structure configured to transition between a first stable shape and a second stable shape. The pad may further include a thermally-conductive compressible foam layer disposed between the fluid containing layer and a patient contact side of the pad. a self-adhering stretchable band configured to secure the pad to the patient. The pad may further include a semi-permeable layer disposed between an underside of the fluid containing layer and a hydrogel layer so that the TTM fluid may migrate from the fluid containing layer to the hydrogel layer.

  • Publication number: 20220347009
    Abstract: Disclosed herein are systems, pads, and methods for targeted temperature management. For example, a pad can include a multilayered pad body, a pad inlet connector, and a pad outlet connector. The pad body can include a conduit layer and a non-adhesive, thermally conductive layer over the conduit layer. The conduit layer can include one or more conduits configured to convey a temperature-controlled fluid as a supply fluid from a hydraulic system of a control module. The one-or-more conduits can also configured to convey the temperature-controlled fluid as a return fluid back to the hydraulic system. The conductive layer can be configured for placement on a portion of a patient's body. The pad inlet connector can include a pad inlet configured for charging the conduit layer with the supply fluid. The pad outlet connector can include a pad outlet configured for discharging the return fluid from the conduit layer.

  • Publication number: 20220233344
    Abstract: Disclosed herein are targeted temperature management (“TTM”) systems, pads, and methods thereof for treating burn wounds. A method of a system for TTM can include a pad-connecting step, a pad-placing step, and a fluid-circulating step. The pad-connecting step can include connecting an inlet and an outlet of a pad to a hydraulic system of a control module. The pad can include a multilayered pad body having a conduit layer configured to convey a temperature-controlled fluid provided by the control module. The pad-placing step can include placing the pad on a wounded portion of a patient's body with a sterile, thermally conductive wound-healing layer of the pad body in contact with a burn wound of the wounded portion of the patient's body. The fluid-circulating step can include circulating the temperature-controlled fluid through the conduit layer to cool the wounded portion of the patient's body, thereby treating the wound to promote healing.

  • Publication number: 20220192865
    Abstract: Disclosed herein are systems, pads, and methods thereof for targeted temperature management. In an example, a pad for targeted temperature management can include a pad body, a conduit system, one or more inlets, and one or more outlets. The pad body can be of a conformable material configured to conform to a body of a patient on the pad. The conduit system can be disposed in the pad body or an overlayer configured for placement over the pad body. The conduit system can include one or more conduits configured to convey a fluid through the pad body or the overlayer. The one-or-more inlets can be configured for charging the conduit system with the fluid, while the one-or-more outlets can be configured for discharging the fluid from the conduit system. Methods of the systems and pads can include methods of use. In another example, a deformable pad can be configured for receiving a neonatal patient.
