Integrated multisectional heat exchanger

Abstract

A multi-sectional therapy wrap can include a first wrap section joined to a second wrap section through a specialized junction that allows the wrap sections to overlap. The junction can also be divided into two portions to facilitate fluid flow between one wrap section and the other wrap section.

         2 . The therapy wrap of  claim 1 , wherein the first wrap section comprises two sheets of material that are welded together to form the first fluid bladder, and the second wrap section comprises a third sheet welded to one of the two sheets that form the first fluid bladder. 
     
     
         3 . The therapy wrap of  claim 1 , further comprising a manifold in fluid communication with the first wrap section, the manifold comprising a fluid inlet and a fluid outlet in fluid communication with the first fluid bladder. 
     
     
         4 . The therapy wrap of  claim 3 , wherein the first interior fence extends from the manifold to divide a portion of the first fluid bladder adjacent the manifold into a fluid outflow tract and a fluid inflow tract. 
     
     
         5 . The therapy wrap of  claim 1 , wherein the first fluid bladder comprises a first set of attachments points that are configured to limit expansion of the first fluid bladder and facilitate fluid flow through the first fluid bladder. 
     
     
         6 . The therapy wrap of  claim 5 , wherein the second fluid bladder comprises a second set of attachment points that are configured to limit the expansion of the second fluid bladder and facilitate fluid flow through the second fluid bladder. 
     
     
         7 . The therapy wrap of  claim 6 , wherein the attachment points of the second set have a larger diameter than the attachment points of the first set. 
     
     
         8 . The therapy wrap of  claim 6 , wherein the attachment points of the second set are spaced farther apart than the attachment points of the first set. 
     
     
         9 . The therapy wrap of  claim 1 , wherein the second wrap section comprises a curved biasing element adapted to bias the second wrap section against a patient's neck. 
     
     
         10 . The therapy wrap of  claim 9 , wherein the second wrap section comprises a pocket for removably receiving the curved biasing element. 
     
     
         11 . The therapy wrap of  claim 1 , wherein the first wrap section comprises one or more stiffening elements adapted to maintain the shape of the first wrap section against compression. 
     
     
         12 . The therapy wrap of  claim 1 , further comprising a spacer disposed between the first wrap section and the second wrap section and adjacent the junction. 
     
     
         13 . The therapy wrap of  claim 1 , further comprising one or more shunts disposed within the junction, wherein the one or more shunts are configured to prevent or reduce the likelihood of kinking in the junction. 
     
     
         14 . A clasp for securing a therapy wrap to a patient's neck, the clasp comprising:
 a first curved arm;   a second curved arm; and   a hinge that rotatably connects the first curved arm with the second curved arm such that that the first curved arm and the second curved arm have an open configuration adapted to receive the patient's neck and a closed configuration adapted to partially surround the patient's neck such that there is a gap between the first curved arm and the second curved arm.   
     
     
         15 . The clasp of  claim 14 , wherein the hinge comprises a torsion spring that biases the first curved arm and the second curved arm into the closed configuration. 
     
     
         16 . The clasp of  claim 14 , further comprising a first support extending from a backside of the first curved arm and a second support extending from a backside of the second curved arm, wherein the first support and the second support are adapted to support the patient's neck in a prone position. 
     
     
         17 . The clasp of  claim 16 , wherein the first support and the second support are wedge shaped. 
     
     
         18 . A multi-sectional therapy wrap, the therapy wrap comprising:
 a first wrap section comprising a first fluid bladder and a gas bladder, the first fluid bladder having a first interior fence that defines a first fluid flow path through 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, 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.   
     
     
         19 . The therapy wrap of  claim 18 , wherein the first wrap section comprises three sheets of material that are welded together to form the first fluid bladder and the second fluid bladder, and the second wrap section comprises a fourth sheet welded to one of the three sheets that form the first fluid bladder. 
     
     
         20 . The therapy wrap of  claim 18 , further comprising a manifold in fluid communication with the first wrap section, the manifold comprising a fluid inlet and a fluid outlet in fluid communication with the first fluid bladder, and a gas line in communication with the gas bladder. 
     
     
         21 . 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   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 third port and a fourth port, wherein the second interior fence divides the receptacle and separates the third port and the fourth port;   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.   
     
     
         22 . The therapy wrap of  claim 21 , wherein the fluid connector is reversibly coupled to the receptacle.
