A lamprey lock device comprising:
- a tubular shaped housing having a proximal end, a distal end and length therebetween, the housing further having an external surface and an internal surface, such that a lumen is formed within the internal surface along the housing length;
- an O-ring having an inner diameter and positioned within the lumen at the distal end;
- a first luer taper adapter having an inner diameter and positioned within the lumen and proximal to the O-ring, wherein the first luer taper adapter has a threaded internal surface;
- and
- an elastomeric ring having an inner diameter and positioned within the lumen and proximal to the first luer taper adapter;
- wherein the inner diameters of the first luer taper adapter and the elastomeric ring are equal to or greater than the inner diameter of the O-ring.
