Infusion hub assembly and fluid line disconnect system

Abstract

An infusion hub assembly, comprising: a hub received in a hole in a wing, the hub having a bore passing therethrough, with an upper portion of the circular hub having an attachment surface thereon; an infusion cannula extending downwardly away from the wing, the infusion cannula being in fluid communication with the bore passing through the hub; a cover having a bore passing therethrough and having an inner attachment surface adapted to mate with the attachment surface on the upper portion of the hub; and a septum positioned in alignment with the bore passing through the cover. An infusion connector set comprising: a first connector; a septum received in the first connector; a second connector; a septum received in the second connector; and a flanged needle which penetrates both the septums in the first and second connectors when the first and second connectors are connected together.

What is claimed is:  
     
         1 . An infusion hub assembly, comprising: 
 a wing having a hole passing therethrough;    a hub received in the hole in the wing, the hub having a bore passing therethrough, with an upper portion of the circular hub having an attachment surface thereon;    an infusion cannula extending downwardly away from the wing, the infusion cannula being in fluid communication with the bore passing through the hub;    a cover having a bore passing therethrough and having an inner attachment surface adapted to mate with the attachment surface on the upper portion of the hub; and    a septum positioned in alignment with the bore passing through the cover.    
     
     
         2 . The assembly of  claim 1 , wherein the upper portion of the hub is circular.  
     
     
         3 . The assembly of  claim 2 , wherein the attachment surface on the upper portion of the circular hub comprises a lip extending circumferentially therearound.  
     
     
         4 . The assembly of  claim 1 , wherein an underside surface of the wing comprises an adhesive layer.  
     
     
         5 . The assembly of  claim 1 , wherein the hole in the wing is a stepped hole and the hub has a stepped outer dimension which fits into the stepped hole in the wing.  
     
     
         6 . The assembly of  claim 5 , wherein both the stepped hole and the hub are circular and the hub has a stepped outer diameter.  
     
     
         7 . The assembly of  claim 1 , further comprising: 
 a needle guide received in the bore of the hub.    
     
     
         8 . The assembly of  claim 7 , wherein the needle guide is funnel shaped.  
     
     
         9 . The assembly of  claim 7 , wherein the infusion cannula is attached to the needle guide.  
     
     
         10 . The assembly of  claim 1 , wherein the upper portion of the cover is circular.  
     
     
         11 . The assembly of  claim 1 , wherein the inner attachment surface on the cover comprises a recess extending circumferentially around an internal surface of the cover.  
     
     
         12 . The assembly of  claim 1 , wherein the cover further comprises an outer attachment surface.  
     
     
         13 . The assembly of  claim 12 , wherein the outer attachment surface on the cover comprises a lip extending circumferentially therearound.  
     
     
         14 . The assembly of  claim 13 , further comprising: 
 a needle guide received in the bore of the hub, wherein the septum is received into the needle guide when the cover is attached to the hub.    
     
     
         15 . The assembly of  claim 13 , further comprising: 
 a removable insertion needle passing through the bore in the cover, the septum and the infusion cannula, wherein a distal end of the insertion needle extends downwardly out of the distal end of the infusion cannula.    
     
     
         16 . The assembly of  claim 1 , further comprising: 
 a rotatable housing having an attachment surface adapted to mate with the outer attachment surface on the upper portion of the cover.    
     
     
         17 . The assembly of  claim 16 , wherein the attachment surface on the rotatable housing comprises a recess extending circumferentially around an internal surface of the rotatable housing.  
     
     
         18 . The assembly of  claim 16 , wherein the rotatable housing has a radial bore.  
     
     
         19 . The assembly of  claim 18 , further comprising: 
 a curved needle passing at least partially through the radial bore in the rotatable housing, wherein a first end of the curved needle is positioned to extend downwardly into the bores in the cover and hub when the rotatable housing is attached to the cover.    
     
     
         20 . The assembly of  claim 19 , further comprising: 
 a tube received into the radial bore of the rotatable housing in fluid communication with the curved needle.
