Abstract
At least some aspects of the present disclosure feature a configurable convective device, including two layers forming a pneumatic structure and an air-guide device. The pneumatic structure includes two portions and an inflatable channel connecting the two portions. In some cases, the air-guide device is disposed within or proximate to the inflatable channel and configured to direct flow of inflation medium when at least one of the two portions are bent.
Claims20
A configurable convective device, comprising:
- a flexible first layer having air permeable surface;
- a flexible second layer joining the first layer by a periphery seal around a common periphery to form a pneumatic structure, the pneumatic structure having a first edge and an opposing second edge, wherein the pneumatic structure comprises a first portion, a second portion, and an inflatable channel connecting the first portion and the second portion;
- at least one opening into the pneumatic structure;
- and
- an air-guide device disposed proximate to a periphery of the inflatable channel connecting the first portion and the second portion, the air-guide device configured to direct flow of inflation medium when at least one of the first and second portions is bent,
- wherein the air-guide device comprises a plurality of staked seals disposed proximate to the periphery seal.

A configurable convective device, comprising:
- a flexible first layer having air permeable surface;
- a flexible second layer joining the first layer by a periphery seal around a common periphery to form a pneumatic structure, the pneumatic structure having a first edge and an opposing second edge;
- at least one opening into the pneumatic structure;
- a separation device disposed proximate to the first edge and adapted to separate a part of the pneumatic structure to a first portion and a second portion, comprising:
- an enclosure seal extending from the first edge toward the second edge;
- and
- a separation element within the enclosure seal;
- and
- an air-guide device disposed proximate to the second edge and between the first portion and the second portion, the air-guide device configured to direct flow of inflation medium at a bending area when at least one of the first and second portions is bent.

An inflatable upper body blanket, comprising:
- a flexible first layer having air permeable surface;
- a flexible second layer joining the first layer by a periphery seal around a common periphery to form a pneumatic structure, the pneumatic structure having a first edge and an opposing second edge, wherein the pneumatic structure comprises a first portion, a second portion, and an inflatable channel connecting to the first portion and the second portion;
- at least one opening into the pneumatic structure;
- and
- an air-guide device disposed between the first portion and the second portion, the air-guide device configured to direct flow of inflation medium at a bending area when at least one of the first and second portions is bent,
- wherein the air-guide device comprises a first set of air-guide seals disposed proximate to the periphery seal close to the first edge.
