  • Patent number: 11234860
    Abstract: Disclosed herein is a sectional warming blanket for patient warming having a structure comprising a first layer of material forming a bottom layer with openings to allow a profusion of air through the bottom layer, a second layer of material forming an upper layer wherein the upper layer is coupled to the bottom layer via a plurality of seals to form a plurality of interconnected air passageways, and an inlet located on the upper or bottom layers. In an embodiment, the sectional warming blanket further comprises an opening configured to receive a coupling device for coupling the sectional warming blanket to an additional sectional warming blanket. In another embodiment, the sectional warming blanket further comprises at least one outline formed from a portion of the structure, such that a section can be removed from the blanket and the blanket is re-sealed by a bonding mechanism along its periphery.

  • Publication number: 20190336328
    Abstract: Described herein is a warming blanket having a structure comprising a first layer of material forming a bottom layer with openings to allow a profusion of air through the bottom layer, a second layer of material forming an upper layer wherein the upper layer is coupled to the bottom layer to form an initial shape of the warming blanket and to form a plurality of interconnected air passageways between the first and second layers of material, wherein at least a portion of the structure is deformable in at least one dimension to reshape the periphery of the warming blanket while maintaining the integrity of the interconnecting air passageways throughout the structure; and wherein the deformable portion of the blanket is deformable by at least a 50% elongation. Examples of materials comprising the deformable portions of the warming blanket include low density polyethylene, metallocene polyethylene, polypropylene, parafilm, and polyurethane.

  • Publication number: 20190060106
    Abstract: Aspects of the present disclose related to a system. The system includes a warming device having at least a first zone and a second zone and a sensor. The system also includes a controller that includes one or more processor circuits configured to receive a first sensor reading from the sensor corresponding to a first zone, wherein the first sensor reading corresponds to a first heat transfer rate. The one or more processor circuits are configured to determine whether the sensor reading is sufficient and increase a first heat transfer rate to a second heat transfer rate in the first zone in response to the sensor reading being insufficient.

  • Publication number: 20190060107
    Abstract: Aspects of the present disclosure relate to a convective blanket that includes an air permeable upper sheet having a periphery. The convective blanket includes a lower sheet bonded to the upper sheet with a peripheral seal proximate to the periphery of the upper sheet to form an interior space therein between the upper and lower sheets. The convective blanket includes a wing portion partially surrounded by a portion of the peripheral seal and a body portion. Additional aspects relate to a system including the convective blanket and a method that uses the convective blanket.
