  • Publication number: 20250177196
    Abstract: Disclosed herein are compact systems for performing targeted temperature management including one or more thermal pad assemblies, each or which includes a thermoelectric device. The thermoelectric device heats or cools a thermal exchange fluid circulating within the thermal contact pad to warm or cool a patient. The thermoelectric device may be included in a temperature control module directly attached to the pad. A modularized temperature control module may selectively include one or more thermoelectric devices coupled with a heat exchanger. Logic stored in memory may, via execution of one or more processors, control the temperature of the thermal exchange fluid by defining a polarity and magnitude of an electrical power supplied to the thermoelectric device. The temperature control module may be selectively attached to and detached from the pad. A pre-use unassembled state of the thermal pad assembly include the pad having the thermal exchanged fluid sealed therein.

  • Publication number: 20250161107
    Abstract: Disclosed herein are medical systems, pads, and methods for exchanging thermal energy between a circulating fluid and a patient. Some pads are configured multiple uses on the same patient or across multiple different patients. Some pads include multiple layers of hydrogel disposed on one or both sides a fluid compartment. Removable hydrogel layers expose other hydrogel layers for subsequent uses of the pad. Removable storage liners encapsulate one or multiple hydrogel layers. Separation liners between adjacent hydrogel layers isolate the adjacent hydrogels from each other and removal of the separation liner extends the operational life a hydrogel layer. Adhesive patches secure the pads to the patient including adhesive patches extending through openings of a pad. Some pads are configured for disinfection, sterilization and/or laundering. In an embodiment, the fluid is air and a vacuum within a compartment of the pad secures the pad to the patient.
