Multi-sectional patient warming blanket

A sectional warming blanket for patient warming, the sectional warming blanket comprising:

• a structure comprising a first layer of material and a second layer of material,
• the first layer of material forming a bottom layer of the warming blanket, the bottom layer configured to allow a profusion of air to pass through the bottom layer, and
• the second layer of material forming an upper layer of the warming blanket, the upper layer coupled to the bottom layer around a periphery of the bottom layer to form an initial shape of the warming blanket and to form an interior space between the first layer of material and the second layer of material comprising a plurality of interconnected air passageways, wherein the passageways are defined by a plurality of seals formed between the upper layer and the bottom layer within an area defined by the periphery;
• an inlet located on the upper layer or the bottom layer, the inlet comprising an inlet passageway configured to receive a flow of air from a source and to provide the flow of air to the interconnected air passageways;
• and
• an opening located on the upper layer or the bottom layer, the opening comprising a removable seal configured to seal an opening passageway coupled to the interconnected air passageways, the removable seal configured to maintain an air seal when in place over the opening passageway;
• wherein an inlet is configured to be coupled to an opening of an additional sectional warming blanket, and to receive the flow of air from the additional sectional warming blanket as the source of the flow of air.
