Integrated multisectional heat exchanger

A multi-sectional therapy wrap, the therapy wrap comprising:

• a first wrap section comprising a first fluid bladder, the first fluid bladder having a first interior fence that defines a first fluid flow path through the first fluid bladder, the first fluid bladder having a fluid connector comprising a first port and a second port, wherein the first interior fence divides the fluid connector and separates the first port from the second port, and the first wrap section being defined by a first perimeter fence;
• an air bladder covering only the first fluid bladder;
• a second wrap section comprising a second fluid bladder, the second fluid bladder having a second interior fence that defines a second fluid flow path through the second fluid bladder, the second fluid bladder having a receptacle comprising a first receiving port and a second receiving port, wherein the second interior fence divides the receptacle and separates the first receiving port and the second receiving port, and the second wrap being defined by a second perimeter fence;
• wherein the fluid connector is fluidically coupled to the receptacle to allow fluid to flow between the first wrap section and the second wrap section,
• wherein the first fluid bladder is formed from first, second, and third sheets of material, the first and second sheets of material being welded together to form a first portion of the first perimeter fence, and the first and third sheets of material being welded together to form a second portion of the first perimeter fence,
• wherein portions of the second and third sheets of material extend beyond the fluid connector and are welded together to form the second perimeter fence,
• wherein each of the first and second perimeter fences have a gap formed therein for the fluid connector, and
• wherein the air bladder comprises a fourth sheet of material that is welded to the first and second sheets of material along the first portion of the first perimeter fence and to the first and third sheets of material along the second portion of the first perimeter fence, such that the first sheet of material is internal to the first wrap section.

A multi-sectional therapy wrap, the therapy wrap comprising:

• a first wrap section comprising a first fluid bladder and a gas bladder operable only on a first fluid bladder, the first fluid bladder having a first interior fence that defines a first fluid flow path through the first fluid bladder, and the first wrap section being defined by a first perimeter fence;
• a second wrap section comprising a second fluid bladder, the second fluid bladder having a second interior fence that defines a second fluid flow path through the second fluid bladder, the second wrap section being defined by a second perimeter fence, wherein the second wrap section overlaps at least a portion of the first wrap section;
• and
• a junction connecting the first fluid bladder of the first wrap section with the second fluid bladder of the second wrap sections, the junction partitioned into a first portion and a second portion with a third interior fence, wherein the third interior fence is aligned with both the first interior fence and the second interior fence to integrate the first fluid flow path with the second fluid flow path,
• wherein the first fluid bladder is formed from first, second, and third sheets of material, the first and second sheets of material being welded together to form a first portion of the first perimeter fence, and the first and third sheets of material being welded together to form a second portion of the first perimeter fence,
• wherein portions of the second and third sheets of material extend beyond the junction and are welded together to form the second perimeter fence,
• wherein each of the first and second perimeter fences have a gap therein for the junction.
