INHIBITING FLUID LEAKAGE AND SPLATTER IN CATHETER DEVICES AND SYSTEMS

Abstract:

A needle tip shield may include a needle passageway that may receive a needle, a tip shield interior space that may receive a needle block, and a fluid restriction member. The fluid restriction member may be configured to restrict fluid leakage into and/or out of the needle tip shield. The fluid restriction member may be selected from the group consisting of: (1) a fluid impedance member located adjacent the needle passageway that may impede fluid from entering into the needle tip shield through the needle passageway; (2) a fluid retention member that may retain fluid within the tip shield interior space; and (3) an anti-splatter member that may inhibit fluid splatter when the needle block moves from an open position to a closed position within the tip shield interior space.
