A power source for a heated garment. The power source includes a housing, one or more battery cells located within the housing, a user interface positioned on the housing, an electrical interface positioned on the housing for connecting to the heated garment, and a controller located within the housing and including an electronic processor and a memory, the controller coupled to the battery cells, the user interface, and the electrical interface. The controller is configured to communicate with the heated garment and a device. Communicating with a device includes at least one of transmitting the status of the battery cells, receiving heated garment preset temperature information, and receiving desired temperature information. Communicating with the heated garment includes at least one of enabling heated garment components, receiving temperature information, receiving garment type information, and controlling heated zones within the heated garment.

A temperature regulated apparatus can include a layered member comprising a first layer of material and a second layer of material connected to the first layer. The layered member can have a first opening formed therein and an interior area defined by the first layer and the second layer. The interior area can be in communication with the first opening. A temperature regulating element adapted to alter the temperature of the layered member can be positioned within the interior area of the layered member, and can be removed from the layered member without disassembling the layered member.

Provided is a warming device which can efficiently warm a blood product and inhibit a liquid in a warming flow path from exceeding an upper limit temperature thereof when liquid delivery of the blood product is stopped. The warming device includes the warming flow path in which the blood product flows and a heat plate which is in contact with the warming flow path to supply heat to the warming flow path. On the heat plate, a heater in a predetermined pattern corresponding to the warming flow path is disposed. The heater is disposed such that an amount of heat generation toward the warming flow path decreases in stages from an upstream side toward a downstream side in the warming flow path and that a decrease rate of the amount of heat generation at each of the stages decreases from the upstream side toward the downstream side.
