1. An insertion device:, comprising:
a housing;
a flexible catheter movable from a first catheter position disposed substantially entirely within said base to a second catheter position in which a free end of said catheter is disposed externally of said base;
an introducer needle fixed to an introducer bub and located within said catheter and movable between a first introducer needle position disposed substantially entirely within said housing and a second introducer needle position in which a free end of said introducer needle is disposed externally of said housing;
a torsion spring for moving said catheter from said first to said second catheter position and said introducer needle from said first to said second introducer needle position to facilitate insertion of said catheter, said introducer needle thereafter being moved by said torsion spring back toward said first introducer needle position to store said introducer needle within said housing with said free end of said catheter remaining disposed externally of said base; and
a mechanical linkage for coupling said torsion spring to said introducer needle hub, said mechanical linkage comprising a first member coupled to said torsion spring for being rotated thereby and a second member coupled between said first member and said needle hub to convert rotational movement of the first member to linear movement of the introducer needle hub.
