Medical connector contamination prevention device

An apparatus configured to receive a female Luer connector, the apparatus comprising:

• a male Luer connector comprising a conical connector and a circumferential collar oriented about a longitudinal axis, the conical connector comprising a proximal portion and a distal portion, the circumferential collar comprising a distal end and an inner surface, wherein:
• the inner surface of the circumferential collar surrounds the proximal portion of the conical connector and does not surround the distal portion of the conical connector, and
• the inner surface of the circumferential collar is threaded and defined by a plurality of peaks and valleys;
• and
• a shield comprising a distal terminating periphery substantially surrounding the longitudinal axis at a distal end of the shield, the shield oriented about the longitudinal axis and surrounding the distal portion of the conical connector, wherein:
• the shield extends beyond the distal portion of the conical connector;
• the shield comprises an inner bore extending from the distal portion of the conical connector to the distal end of the shield, the inner bore of the shield having a diameter larger than a diameter of an inner bore of the circumferential collar;
• the shield is positionally fixed relative to the circumferential collar;
• the shield comprises a continuous inner surface;
• and
• the shield is an adhered film.
