Flow-path constituting body

Abstract

A flow-path constituting body includes at least two port parts where a fluid flows in or flows out, a flow path that is in communication with the port parts, and a flexible film for forming the flow path. The flow path is constructed by using a non-bonded area defined by a bonded area of the flexible film. Alternatively, a flow-path constituting body includes at least two port parts where a fluid flows in or flows out and a flow path that is in communication with the port parts. At least a part of the flow path is constructed by a non-bonded area defined by a bonded area of a flexible film or a flexible film and another member.

1 . A flow-path constituting body comprising: 
 at least two port parts where a fluid flows in or flows out;    a flow path which is in communication with the port parts; and    a flexible film for forming the flow path    wherein the flow path is constructed by using a non-bonded area defined by a bonded area of the flexible film.    
   
   
       2 . The flow-path constituting body according to  claim 1 , wherein the flow path is constructed so as to be integrally provided with a plurality of flow paths or a branched flow path by using the flexible film.  
   
   
       3 . The flow-path constituting body according to  claim 1 , wherein the flexible film is a laminated film constructed of a metal layer and a resin layer.  
   
   
       4 . The flow-path constituting body according to  claim 1 , further comprising a stagnation part comprised of a closed non-bonded area provided on a side of the flow path and in communication with the flow path.  
   
   
       5 . The flow-path constituting body according to  claim 4 , further comprising a deformation member accommodated in the closed non-bonded area, whose volume is reduced by compressive deformation.  
   
   
       6 . The flow-path constituting body according to  claim 4 , wherein the closed non-bonded area is disposed on an upper side of the flow path.  
   
   
       7 . The flow-path constituting body according to  claim 1 , further comprising a cross-section holding means for maintaining a flowing cross-section of the flow path.  
   
   
       8 . The flow-path constituting body according to  claim 7 , wherein the cross-section holding means is either of an inner support member which is disposed within the non-bonded area of the flexible film or an outside support member which holds one side of the flexible film in the non-bonded area so as to separate from the other side of the flexible film in the non-bonded area.  
   
   
       9 . A flow-path constituting body comprising: 
 at least two port parts where a fluid flows in or flows out; and    a flow path which is in communication with the port parts;    wherein at least a part of the flow path is constructed by a non-bonded area defined by a bonded area of a flexible film or a flexible film and another member.    
   
   
       10 . The flow-path constituting body according to  claim 9 , wherein the flow path is constructed so as to be integrally provided with a plurality of flow paths or a branched flow path by using the flexible film.  
   
   
       11 . The flow-path constituting body according to  claim 9 , wherein the flexible film is a laminated film constructed of a metal layer and a resin layer.  
   
   
       12 . The flow-path constituting body according to  claim 9 , further comprising a stagnation part which comprises of a closed non-bonded area provided on a side of the flow path and is in communication with the flow path.  
   
   
       13 . The flow-path constituting body according to  claim 12 , further comprising a deformation member accommodated in the closed non-bonded area, whose volume is reduced by compressive deformation.  
   
   
       14 . The flow-path constituting body according to  claim 12 , wherein the closed non-bonded area is disposed on an upper side of the flow path.  
   
   
       15 . The flow-path constituting body according to  claim 9 , further comprising a cross-section holding means for maintaining a flowing cross-section of the flow path.  
   
   
       16 . The flow-path constituting body according to  claim 9 , wherein the another member is a plate member or a block member made of synthetic resin or metal and has a higher rigidity than the flexible film.
