Safety syringe

A syringe apparatus, comprising:

• a barrel;
• a plunger movable within said barrel;
• a needle assembly fixed to said barrel;
• a deformable base positioned between said barrel and said needle assembly;
• sacrificial support means in said needle assembly for positioning said deformable base;
• a hollow needle containment tube formed in said needle assembly defining a passageway extending between said deformable base and an opposite side of said needle assembly;
• energy storage means within said passageway;
• a hollow needle passing through said passageway;
• an enlarged head on said needle within said needle assembly engaged between said deformable base said energy storage means;
• and
• a rupturable boot on said plunger for moving a fluid within said barrel through the hollow of said needle when said plunger is moved through said barrel toward said needle assembly;
• whereby when said plunger moves through said barrel toward said needle assembly a fluid is moved from said barrel through the hollow of said needle and when said boot contacts said deformable base continued movement thereof moves said deformable base downwardly severing said sacrificial support means with continued movement until said enlarged head of said needle ruptures said rupturable boot, said deformable base then releasing said needle with said enlarged head to project said needle with said enlarged head into the interior of said plunger.

A syringe comprising:

• a barrel having a first end and an opposite second end;
• a plunger having a forward end and movable within the barrel from the second end of the barrel towards the first end, the plunger having a hollow interior communicating with the forward end;
• a hollow needle having a pointed front extending through the first end of the barrel and a rear end received within the barrel;
• energy storage means positioned in the barrel between the first end and the opposite second end in engagement with the needle;
• and
• an absorbent material within said syringe;
• whereby a fluid is moved from within the barrel through the needle as the plunger moves through the barrel to then allow the energy storage means to eject the needle into the interior of the plunger where any excess liquid material is absorbed by said absorbent material.
