The method comprises receiving user-specific data comprising at least temperature indications measureable, by a number of sensor devices, at skin surface of the user upon delivery of cooling fluid 201 into the cabin via the cooling unit followed by intake and recirculation of said cooling fluid by fluid circulation units, which further return recirculated cooling fluid 301 inside said cabin, and based on said user-specific data, selectively adjusting distribution of said cooling fluid 201, 301 inside the cabin, in terms of at least speed and/or direction of a fluidic flow, to a predetermined level during an operation cycle.

A thermal device includes an inflatable non-perforated blanket, a conduit structure, and a recirculating assembly. The inflatable non-perforated blanket is configured to transport warm air internally. The conduit structure is configured to provide conduit to transport the warm air externally to the inflatable non-perforated blanket. The recirculating assembly is configured to inflate the inflatable non-perforated blanket with the warm air and: (1) to cause the warm air to flow from the first port to the second port in a first direction, and (2) to recirculate the warm air through the conduit structure to flow from the second port to the first port in the first direction. The inflatable non-perforated blanket includes first and second sheets. The first sheet faces ambient air and has a first thermal conductivity. The second sheet faces the subject body and has a second thermal conductivity higher than the first thermal conductivity.

A cold and/or hot compress system, comprising a water bag (101), an air bag (102), a water circulation assembly (2) in fluid communication with the water bag (101) and a pneumatic assembly (3) in fluid communication with the air bag (102). In the cold and/or hot compress system, the water circulation assembly (2) is independent from the pneumatic assembly (3). Therefore, during the delivery of a cooling or heating therapy, the independent pneumatic assembly (3) can be driven by an air pressure waveform defined by parameters pre-stored in a control panel (402) to cause the water bag (102) to apply cold/hot compress to a region of interest of a patient's body. Independent water and air circulation paths in the system avoid interference between water and air flows therein, allowing the system to applied more stable compress with minimized pressure errors. Moreover, a more constant water flow rate and a more uniform temperature distribution across the surface of the water bag are achievable.

A cold and hot compress pack includes a first sheet (110), a second sheet (120), a third sheet (130), a first weld seam (210), a second weld seam (220), a gas port (310) and at least two liquid ports (320). The first sheet (110), the second sheet (120) and the third sheet (130) are sequentially stacked one above another. The first weld seam (210) joins the first sheet (110), the second sheet (120) and the third sheet (130) at a same planimetric position. The second weld seam (220) surrounds the first sheet (110), the second sheet (120) and the third sheet (130) and joins them together at a same planimetric position. The second weld seam (220) is joined to one end of the first weld seam (210), thereby forming a first cavity (141) between the first sheet (110) and the second sheet (120) and a second cavity (142) between the second sheet (120) and the third sheet (130). The gas port (310) is arranged between any two of the liquid ports (320) so as to be spaced apart from both. The at least two liquid ports (320) are in communication with the second cavity (142), and the gas port (310) is in communication with the first cavity (141). An end of the first weld seam (210) joined to the second weld seam (220) extends between the gas port (310) and any one of the liquid ports (320) while being spaced apart from both.
