Abstract

A touch-contamination protected spike connector is provided for coupling a plastic fluid conduit to a port extending from a medical solution container. The spike defines a longitudinal bore and has an angled tip, and carries a flange which extends outwardly from the spike. A tube surrounds and is concentric with a major portion of the spike, with the tube having a dimension suited for coupling to the port with a snug pressure fit. A spacer is interposed between the spike and the tube. The flange and surrounding tube cooperate to enable the spike to be connected to the port with the chance of bacterial contamination caused by accidental touching of the spike being minimized.

Claims

1. A touch-contamination protected spike connector for coupling a plastic fluid conduit to a port extending from a medical solution container, the port having a transverse diaphragm adapted for breakage by the spike to provide communication from the plastic fluid conduit to the medical solution container, the improvement comprising:

a rigid spike defining a longitudinal bore and having an angled tip;

a flange extending radially outwardly from said rigid spike;

a tube surrounding a major portion of said spike and extending in a generally parallel direction to said spike with the internal wall of said tube being spaced from the external wall of said spike;

a spacer immovably interposed between the spike and the tube, said spacer being formed of resilient material and being connected to said flange and filling a portion of the volume between said spike and said tube;

said angled tip having a distal end which extends a greater distance than said tube in the longitudinal direction.

2. A spike connector as described in claim 1, said flange extending radially from said spike a greater radial distance than the tube'"'"'s radial distance from the spike.

3. A spike connector as described in claim 1, said spike having a generally circular cross-sectional configuration and said tube being generally concentric therewith.

4. A spike connector as described in claim 1, said spacer being formed of a vinyl material and said tube being formed of an ethylene vinyl acetate copolymer.

5. A spike connector as described in claim 1, said tubing being formed of a material from the group consisting of Teflon®

polytetrafluoroethylene, a polyolefin, and an ethylene vinyl acetate copolymer.
