Hypodermic implant device

Abstract

A hypodermic implant device, comprising a barrel; an upper piston segment engaged with an inner wall of the barrel; an axially aligned needle extendably distally out of the barrel for insertion into an object when the upper piston segment is moved distally within the body; a lower piston segment push rod in alignment with the needle, so that upon distal movement of the lower piston segment, the push rod moves distally through the needle expelling a releasable implant housed in the needle; and a means for retraction of the needle into a needle receptacle in the barrel.

         12 . A hypodermic implant device, comprising: (a) a barrel comprising an open end and an inner end each in axial alignment with a central axis; (b) a piston, comprising an upper piston segment and a lower piston segment, matingly engaged with an inner wall for sliding movement in the barrel; (c) a central axis aligned needle comprising an inlet end, a nozzel end, and a means for guiding the nozzel out of the barrel upon distal movement of the upper piston segment; and (d) a lower piston segment push rod aligned with the needle bore for distal movement within the bore upon distal movement of the lower piston segment.  
     
     
         13 . The hypodermic implant device of  claim 12 , further comprising: (a) a needle receptacle and (b) a means for engagement of the needle to at least one piston segment, so that upon retraction of the at least one piston segment, the nozzel is fully retracted into the needle receptacle.  
     
     
         14 . The hypodermic implant device of  claim 13 , further comprising a means for tilting the needle upon its retraction into the needle receptacle.
