1. A one piece, integral syringe comprising,
a syringe barrel having an open proximal end configured for receiving a plunger, and distal outlet end;
a post extending axially from said distal end of said syringe barrel, said post having an axial passage communication with a cavity of said syringe barrel and a distal end face;
a cannula received in said axial passage of said post and extending from said distal end of said syringe barrel, said cannula having a beveled distal end for injection into a subject's skin;
an outer annular collar surrounding said post and extending axially from said distal end of said syringe barrel and defining an annular recess between said post and said collar, said collar having a distal end face positioned relative to said distal end face of said post a distance to define a radius of curvature of about 6.0 to 10.0 mm, whereby said distal end face of said collar and said distal end face of said post contact the skin and provide a controlled deformation of the skin for inserting the cannula to a selected depth and inhibit tenting of the skin around said cannula;
wherein said syringe barrel further includes at least one flange extending radially outward from a proximal end of said syringe barrel for gripping by a user, said flange having a proximal surface with at least one tactile member, and a distal surface with at least one tactile member;
wherein said tactile member on said proximal surface of said flange is a dimple projecting outward from said proximal surface and where said tactile member on said distal surface is a recess; and
wherein said at least one recess in said distal surface includes a projecting detent.
