Abstract

At least some aspects of the present disclosure feature a convective device, comprising: a pneumatic structure formed by one or more layers, a partially detachable access duct, and a separation device disposed on a side of the partially detachable access duct. The partially detachable access duct in fluid connection with the pneumatic structure.

First claim

What is claimed is:

1. A convective device, comprising:
a pneumatic structure formed by one or more layers,
a tubular structure configured to be partially detached, extending from a first end to an opposing second end, wherein the tubular structure is detachable from the pneumatic structure and configured to receive a hose in connection with an inflation medium source at the first end, and wherein the second end of the tubular structure is in fluid connection with the pneumatic structure, and
a separation element comprising at least one of a line of weakness, perforation, and slit disposed on a side of the tubular structure between the tubular structure and the pneumatic structure, the separation element extending from the first end to the second end,
wherein the tubular structure comprises an air-guide device disposed in the tubular structure, wherein the air-guide device is configured to direct flow of inflation medium when the tubular structure is bent,
wherein the air-guide device is disposed proximate to and no more than one inch (2.54 cm) from a longitudinal edge of the tubular structure forming one or more creases proximate to the air-guide device when the tubular structure is inflated.

2. The convective device of claim 1 , wherein the separation element comprises a seal surrounding the separation element.

3. The convective device of claim 1 , wherein the air-guide device comprises a plurality of staked seals extending from a periphery seal.

4. The convective device of claim 3 , wherein at least part of the staked seals are disposed proximate to the longitudinal edge of the tubular structure.

5. The convective device of claim 4 , wherein at least part of the staked seals are disposed generally equal spacing along the longitudinal edge.

6. A convective system, comprising:
a hose configured to connect to an inflation medium source;
a convective device, comprising:
a pneumatic structure formed by one or more layers,
a tubular structure configured to be partially detached, extending from a first end to an opposing second end, wherein the first end of the tubular structure is detachable from the pneumatic structure and configured to receive the hose at the first end, and wherein the second end of the tubular structure is in fluid connection with the pneumatic structure, and
a separation element comprising at least one of a line of weakness, perforation, and slit disposed on a side of the tubular structure between the tubular structure and the pneumatic structure, the separation element extending from the first end to the second end,
wherein the tubular structure comprises an air-guide device disposed in the tubular structure, wherein the air-guide device is configured to direct flow of inflation medium when the tubular structure is bent,
wherein the air-guide device is proximate to and disposed no more than one inch (2.54 cm) from a longitudinal edge of the tubular structure forming one or more creases proximate to the air-guide device when the tubular structure is inflated;

a hose clamp, comprising:
an encircling element having an inner surface and an opposing outer surface,
a grabbing component extending from the outer surface of the encircling element, and
an engaging component disposed on the inner surface of the encircling element,

wherein the hose clamp is configured to be used at the connection of the tubular structure and the hose.

7. The convective system of claim 6 , wherein the separation element comprises a seal surrounding the separation element.

8. The convective system of claim 6 , wherein the air-guide device comprises a plurality of staked seals extending from a periphery seal.

9. The convective system of claim 8 , wherein at least part of the staked seals are disposed proximate to the longitudinal edge of the tubular structure.

10. The convective system of claim 9 , wherein at least part of the staked seals are disposed generally equal spacing along the longitudinal edge.

11. The convective system of claim 6 , wherein the encircling element has a first end and a second end, and wherein the engaging component comprises a first set of engaging elements disposed proximate to the first end.

12. The convective system of claim 11 , wherein the engaging component further comprises a second set of engaging elements disposed proximate to the second end.
