Abstract
At least some aspects of the present disclose feature a flow control device to be used between two inflatable sections. The flow control device is a one-way flow control device allowing inflating medium to flow in one direction. In such embodiments, the flow control device is in an open state when a first inflatable section is inflated such that a second inflatable section is also inflated. The flow control device is in close state when the second inflatable section is inflated such that the first inflatable section is not inflated.
Claims15
A convective device, comprising:
- a first inflatable section having a first opening,
- a second inflatable section having a second opening, and
- a flow control device disposed between the first inflatable section and the second inflatable section, the flow control device configured to open when the second inflatable section is inflated with inflating medium and remain closed when the first inflatable section is inflated with inflating medium, wherein an inlet pressure at the first opening or the second opening is less than 100 mmHg when inflated and a volume of the first inflatable section or the second inflatable section increases by greater than 100% when inflated.
A convective device, comprising:
- a first inflatable section having a first opening,
- a second inflatable section having a second opening, and
- a flow control device disposed between the first inflatable section and the second inflatable section, the flow control device configured to open when the second inflatable section is inflated with inflating medium and remain closed when the first inflatable section is inflated with inflating medium, wherein the flow control device comprises a releasable adhesive strip.
