Filling needle

Abstract

Disclosed is a filling needle of a fluid-dispensing system, the filling needle including a needle portion that is a metallic material, a hub affixed to an end of the needle portion, wherein the hub is non-metallic and configured to securely associate with the fluid-dispensing system, and allow the fluid-dispensing system to be in fluid communication with the needle portion.

1 . A filling needle of a fluid-dispensing system, the filling needle comprising;
 a needle portion that is a metallic material; and   a hub affixed to an end of said needle portion, wherein said hub is non-metallic and configured to securely associate with the fluid-dispensing system, and allow the fluid-dispensing system to be in fluid communication with said needle portion.   
   
   
       2 . The filling needle of  claim 1 , wherein said hub is configured to securely associate with a tubing of the fluid-dispensing system via a frictional fit. 
   
   
       3 . The filling needle of  claim 1 , wherein said hub is a plastic material. 
   
   
       4 . The filling needle of  claim 3 , wherein said plastic material of said hub is a medical grade polymer, and said metal material of said needle portion is stainless steel. 
   
   
       5 . The filling needle of  claim 1 , wherein said hub is a rubber material. 
   
   
       6 . A fluid dispensing system comprising:
 a reservoir configured to hold bulk fluid;   tubing that is fluidly communicable with said reservoir; and   at least one filling needle, each of said at least one filling needles including a needle portion that is a metallic material and a hub affixed to an end of said needle portion, wherein said hub is non-metallic and configured to securely associate with said tubing, and allow said tubing to be in fluid communication with said needle portion.   
   
   
       7 . The system of  claim 6 , further including at least one pump disposed with at least one of said reservoir, said tubing, and said at least one filling needle, wherein said at least one pump is configured to pump a desirable amount of fluid into and from said filling needle. 
   
   
       8 . The system of  claim 6 , wherein said hub is permanently affixed to said tubing, said tubing being configured for detachability from said reservoir. 
   
   
       9 . The system of  claim 8 , wherein said tubing is of unitary construction with said hub, and wherein said tubing is the same non-metallic material as said hub. 
   
   
       10 . The filling needle of  claim 6 , wherein said hub is a plastic material. 
   
   
       11 . The filling needle of  claim 10 , wherein said plastic material of said hub is a medical grade polymer, and said metal material of said needle portion is stainless steel. 
   
   
       12 . The filling needle of  claim 6 , wherein said hub is a rubber material. 
   
   
       13 . The filling needle of  claim 8 , wherein said tubing is permanently affixed to said hub via at least one of polymer welding, electron processes, and gamma ray processes.
