1. A needle tip shield comprising:
a needle passageway formed through the needle tip shield for receiving a needle therethrough;
a tip shield interior space that receives a needle block therein, wherein the needle block comprises a V-clip, the tip shield interior space comprising an opening for inserting the needle block into the tip shield interior space; and
a fluid restriction member configured to restrict fluid leakage into and/or out of the needle tip shield, wherein the fluid restriction member comprises an anti-splatter member that inhibits fluid splatter when the needle block moves from an open position to a closed position within the tip shield interior space, wherein the anti-splatter member comprises a damping member and a stiffening member coupled to an inner surface of a V-portion of the V-clip, wherein the damping member is disposed in between the stiffening member and the V-clip.
