  • Publication number: 20250073061
    Abstract: A thermal control unit includes a supply circuit, a return circuit, a fluid channel, a drain coupled to the fluid channel, and at least one hose circuit connecting the supply circuit and the return circuit. A supply valve may be coupled to the supply circuit and a return valve may be coupled to the return circuit. When the drain is opened, the return valve can open to allow ambient air to enter the return column and to create a siphon to drain the fluid in the thermal control unit. The supply valve can open after the return valve and allow ambient air to enter the supply circuit. The supply valve may allow less air to enter the thermal control unit than the return valve to preserve the siphon through the draining process.

  • Patent number: 12226340
    Abstract: A thermal control unit for controlling a patient's temperature includes a fluid outlet for delivering temperature-controlled fluid to a patient, a pump, a heat exchanger, and a controller that automatically pauses thermal treatment of the patient prior the patient reaching a target temperature. During the pause, the controller assesses a reaction of the patient and changes a temperature of the fluid only inside the thermal control unit if the patient is likely to reach the target temperature without further thermal treatment. However, if the patient is unlikely to reach the target temperature without further thermal treatment, the controller restarts the thermal treatment. The controller may pause thermal treatment again prior to reaching the target temperature and assess the patient's reaction. In some embodiments, the controller may selectively include and exclude a fluid reservoir in a circulation channel within the thermal control unit.
