Safety Needle Set For Delivering Fluid To An Access Port

Abstract

A safety needle set for delivering fluid to an access port, the safety needle set having insertion and safety configurations. The safety needle set includes a needle assembly and a base assembly. The needle assembly includes a needle having a distal end with a non-coring tip, the distal end angled with respect to a proximal end of the needle. The needle assembly also includes a pair of foldable wings coupled to the needle, including a first wing and a second wing. The first wing may have a recess, and the second wing may have a protrusion, such that when the first wing contacts the second wing in a wing folded configuration, the recess receives the protrusion. The base assembly includes a housing, a safety needle assembly at least partially disposed in an interior of the housing, and an interface pad coupled to a bottom surface of the housing.

What is claimed is: 
     
         1 . A safety needle set designed for delivering fluid to an access port, comprising:
 a needle assembly, comprising;
 a needle, comprising:
 a gauge; 
 a proximal end; and 
 a distal end including a non-coring tip, the distal end angled with respect to the proximal end; 
 
 a tube having a distal end coupled to the proximal end of the needle, and a proximal end coupled to a connector; 
 a clamp disposed over the tube between the needle and the connector; and 
 a pair of foldable wings coupled to the needle, including a first wing having a recess, and a second wing having a protrusion, the recess receiving the protrusion when the first wing contacts the second wing in a wing folded configuration, wherein at least one of the first wing and the second wing includes an indication of the gauge of the needle; and 
   a base assembly, comprising:
 a housing having a bottom surface including an opening in communication with an interior of the housing, the bottom surface defined by an outer perimeter; 
 a safety needle assembly at least partially disposed in the interior of the housing; and 
 an interface pad coupled to the bottom surface of the housing around the outer perimeter, wherein the interface pad does not cover the opening in the bottom surface, 
   the safety needle set having an insertion configuration and a safety configuration, wherein the distal end of the needle extends through the housing and the opening in the bottom surface in the insertion configuration, and wherein the non-coring tip is prevented from exiting the housing in the safety configuration.   
     
     
         2 . The safety needle set according to  claim 1 , wherein the base assembly includes a first connecting element, and wherein the needle assembly includes a second connecting element, the first connecting element and second connecting element releasably coupling the needle assembly to the base assembly in the insertion configuration. 
     
     
         3 . The safety needle set according to  claim 2 , wherein the interface pad is permanently coupled to the bottom surface of the housing. 
     
     
         4 . The safety needle set according to  claim 1 , wherein the interface pad includes shape that matches a shape of a bottom surface of the needle hub, the interface pad including a hole through which the needle extends in the insertion configuration. 
     
     
         5 . The safety needle set according to  claim 1 , wherein the interface pad includes at least one of a haemostatic agent and an antimicrobial agent. 
     
     
         6 . The safety needle set according to  claim 5 , wherein the antimicrobial agent includes chlorhexidine gluconate. 
     
     
         7 . The safety needle set according to  claim 5 , wherein the haemostatic agent includes a hydrocolloid. 
     
     
         8 . The safety needle set according to  claim 5 , wherein the haemostatic agent includes microdispersed oxidized cellulose. 
     
     
         9 . The safety needle set according to  claim 1 , wherein the interface pad includes a foam material. 
     
     
         10 . The safety needle set according to  claim 9 , wherein the foam material includes an aromatic polyether polyurethane. 
     
     
         15 . The safety needle set according to  claim 1 , wherein the gauge of the needle is 20, and wherein “20G” is indicated on a top surface of at least one of the first wing and the second wing.
