Breathing bag including integrally formed connector and distensible portions

Abstract

A breathing bag including a distensible bag portion and an integrally formed neck portion thicker than the distensible bag portion and sufficiently thick to be connected directly to a male fitting; the distensible bag portion may be fluted.

1 . A breathing bag for being connected directly to a male fitting, comprising: 
 a fluted distensible bag portion and an integrally formed connector portion sufficiently rigid to connect directly to the male fitting, said fluted distensible bag portion and said connector portion being one piece and said connector portion being thicker at all points therealong than said distensible bag portion.    
   
   
       2 . A breathing bag for being connected directly to a male fitting, comprising: 
 a fluted distensible bag portion having a first thickness and a connector portion formed integrally with said distensible bag portion and having a second thickness greater at all points therealong than said first thickness, said distensible bag portion and said connector portion being one piece, and said connector portion being sufficiently thick to connect directly to the male fitting.    
   
   
       3 . The breathing bag according to  claim 2 , wherein said second thickness is about seven times thicker than said first thickness.  
   
   
       4 . The breathing bag according to  claim 2 , wherein said second thickness is from about 6 to about 8 times thicker than said first thickness.  
   
   
       5 . The breathing bag according to  claim 2 , wherein said distensible bag portion and said connector portion provide an internal airway therebetween and wherein said breathing bag further includes means formed integrally therewith for preventing occlusion of said airway.  
   
   
       6 . The breathing bag according to  claim 5 , wherein said means comprise at least two internal ridges molded into the integral connection between said distensible portion and said connector portion.  
   
   
       7 . The breathing bag according to  claim 2 , wherein said connector portion is generally cylindrical and includes an outer portion provided with an integrally formed, radially outwardly extending and generally annular ridge.  
   
   
       8 . The breathing bag according to  claim 7 , wherein said ridge is generally rectangular in transverse cross-section.  
   
   
       9 . The breathing bag according to  claim 2 , wherein said connector portion is generally cylindrical and includes a lower portion adjacent the integral connection between the connector portion and the distensible bag portion and which lower portion is provided with an integrally formed, radially outwardly extending and generally annular ridge.  
   
   
       10 . The breathing bag according  claim 9 , where in said ridge is generally semi-circular in transverse cross-section.  
   
   
       11 . The breathing bag according to  claim 2 , wherein said connector portion includes an outer end portion provided with an internal, outwardly flared, and generally annular beveled surface.  
   
   
       12 . The breathing bag according to  claim 7 , wherein said generally annular ridge is a first generally annular ridge and wherein said connector portion further includes a lower portion adjacent the integral connection between the connector portion and the distensible bag portion, and wherein said lower portion is provided with an integrally formed and radially outwardly extending second generally annular ridge.  
   
   
       13 . The breathing bag according to  claim 12 , wherein said first generally annular ridge and said generally annular ridge are parallel and spaced apart.  
   
   
       14 . The breathing bag according to  claim 12 , wherein said connector portion further includes an outer end portion provided with an internal, outwardly flared and generally annular beveled surface.  
   
   
       15 . The breathing bag according to  claim 7 , wherein said connector portion further includes an outer end portion provided with an internal, outwardly flared and generally annular surface.  
   
   
       16 . The breathing bag according to  claim 2 , wherein said distensible bag portion has a single opening.  
   
   
       17 . A breathing bag for being connected directly to a male fitting, comprising: 
 a distensible bag portion and an integrally formed connector portion sufficiently rigid to connect directly to the male fitting, said distensible bag portion and said connector portion being one piece, said distensible bag portion having a first thickness and said connector portion having a second thickness greater than said first thickness at all points along said connector portion.
