Compressible needleless valve assembly

Abstract

A valve for a needleless valve system. The valve includes a body configured to be disposed in the needleless valve system and controlling fluid flow through the needleless valve system and wherein the body is tail-less. The body includes a continuous top surface, and a compression feature configured to control how the body is compressed to allow fluid flow through the needleless valve system.

What is claimed is: 
     
         1 . A needleless valve assembly comprising:
 a compressible valve body having a retaining flange and a head, the retaining flange having a proximal end and a distal end, and the head having a proximal end and a distal end, wherein the proximal end of the retaining flange and the proximal end of the head define a proximal most end of the valve body, and the head comprises a continuous top surface and an asymmetrical cavity that extends from the proximal most end of the valve body toward the distal end of the head; and   a housing, wherein the valve body is positioned within the housing for controlling a fluid flow through the needleless valve assembly.   
     
     
         2 . The needleless valve assembly of  claim 1 , wherein the continuous top surface is non-planar during the fluid flow through the needleless valve assembly. 
     
     
         3 . The needleless valve assembly of  claim 1 , wherein the continuous top surface is tilted relative to a top surface of the housing during the fluid flow through the needleless valve assembly. 
     
     
         4 . The needleless valve assembly of  claim 1 , wherein the continuous top surface is deformed in a V-shape during the fluid flow through the needleless valve assembly. 
     
     
         5 . The needleless valve assembly of  claim 1 , wherein the continuous top surface does not require a slit. 
     
     
         6 . The needleless valve assembly of  claim 1 , wherein the proximal end of the retaining flange and the proximal end of the head are coplanar. 
     
     
         7 . The needleless valve assembly of  claim 1 , wherein a cross-sectional profile of the asymmetrical cavity, along a central longitudinal axis of the valve body, comprises an amorphous shape. 
     
     
         8 . A compressible valve body for controlling a fluid flow through a compressible needleless valve assembly, the valve body comprising a retaining flange and a head, the retaining flange having a proximal end and a distal end, and the head having a proximal end and a distal end, wherein the proximal end of the retaining flange and the proximal end of the head define a proximal most end of the valve body, and the head comprises a continuous top surface and an asymmetrical cavity that extends from the proximal most end of the valve body toward the distal end of the head. 
     
     
         9 . The compressible valve body of  claim 8 , wherein the continuous top surface is non-planar when the valve body is uncompressed. 
     
     
         10 . The compressible valve body of  claim 8 , wherein the continuous top surface is tilted relative to a plane defined by the proximal most end of the valve body when the distal end of the head is compressed toward the proximal most end of the valve body. 
     
     
         11 . The compressible valve body of  claim 8 , wherein the continuous top surface is deformed in a V-shape when the distal end of the head is compressed toward the proximal most end of the valve body. 
     
     
         12 . The compressible valve body of  claim 8 , wherein the continuous top surface does not require a slit. 
     
     
         13 . The compressible valve body of  claim 8 , wherein the proximal end of the retaining flange and the proximal end of the head are coplanar. 
     
     
         14 . The compressible valve body of  claim 8 , wherein a cross-sectional profile of the asymmetrical cavity, along a central longitudinal axis of the valve body, comprises an amorphous shape. 
     
     
         15 . The compressible valve body of  claim 8 , wherein the valve body comprises a port therethrough, such that a fluid can move entirely through the valve body.
