Abstract

A filling aid. The filling aid includes a needle housing portion including at least one tab having a starting position and a filling position, and a filling needle cradle including a filling needle, the filling needle cradle slidable connected to the needle housing portion and having a starting position and a filling position, wherein when the at least one tab on the needle housing moves from a starting position to a filling position, the filling needle cradle slides from a starting position to a filling position, and wherein when the at least one tab on the needle housing moves from a filling position to a starting position, the filling needle cradle slides from a filling position to a starting position.

What is claimed is: 
     
         1 . A filling aid comprising:
 a needle housing portion comprising at least one tab having a starting position and a filling position; and   a filling needle cradle comprising a filling needle, the filling needle cradle slidable connected to the needle housing portion and having a starting position and a filling position,   wherein when the at least one tab on the needle housing moves from a starting position to a filling position, the filling needle cradle slides from a starting position to a filling position, and   wherein when the at least one tab on the needle housing moves from a filling position to a starting position, the filling needle cradle slides from a filling position to a starting position.   
     
     
         2 . The filling aid of  claim 1  wherein the needle housing portion further comprising at least one groove feature. 
     
     
         3 . The filling aid  claim 1  wherein the filling needle cradle comprising at least one orientation bar that fits into the groove feature of the needle housing whereby allowing the filling needle cradle to slide with respect to the needle housing. 
     
     
         4 . The filling aid of  claim 1  wherein the filling needle cradle comprising a connector for a filling syringe. 
     
     
         5 . The filling aid of  claim 1  wherein the connector for a filling syringe comprising a luer connector. 
     
     
         6 . The filling aid of  claim 1  wherein the filling needle cradle comprising a filling needle. 
     
     
         7 - 13 . (canceled) 
     
     
         14 . A system for filling a reservoir comprising:
 a disposable housing assembly comprising a reservoir;   a fill adapter for releasably engaging the disposable housing assembly, the fill adapter comprising a pump chamber plunger; and   a filling aid configured to releasably engage the fill adapter,   wherein the pump chamber plunger actuates a pump chamber in the disposable housing assembly when the disposable housing assembly and the fill adapter are engaged.   
     
     
         15 . The system of  claim 14  wherein the filling aid comprising:
 a needle housing portion comprising at least one tab having a starting position and a filling position; and 
 a filling needle cradle comprising a filling needle, the filling needle cradle slidable connected to the needle housing portion and having a starting position and a filling position, 
 wherein when the at least one tab on the needle housing moves from a starting position to a filling position, the filling needle cradle slides from a starting position to a filling position. 
 
     
     
         16 . The system of  claim 14  wherein the fill adapter comprising:
 a housing having a cavity portion configured to attach to the disposable housing assembly; 
 a filling aid base connected to the housing configured to receive the filling aid; and 
 a button assembly actuator springingly attached to the housing, the button assembly actuator comprising one or more button assemblies. 
 
     
     
         17 . The system of  claim 14  further comprising a filling syringe, the filling syringe configured to connect to the filling aid. 
     
     
         18 . The system of  claim 14  wherein the filling needle cradle further comprising a connector for a filling syringe.
