Abstract:
1. A safety device for occluding a flow through a vascular access system, the safety device comprising: a casing having an inlet port and an outlet port; a fluid pathway in communication with the inlet port and the outlet port; an occlusion valve interposed between the inlet port and the outlet port, the occlusion valve having an inactivated position and an activated position, the occlusion valve further comprising a piston having a first end slidably positioned in a compression chamber, a clip forming a terminal end portion of the piston, and a clip catch forming a terminal end portion of an inner wall surface of the compression chamber, the compression chamber directly abutting the fluid pathway, and the piston having a second end slidably positioned in a housing chamber, a seal being formed between the second end and the housing chamber in the inactivated position, wherein upon activation of the occlusion valve, the piston translates within the compression chamber from the inactivated position to the activated position, the clip and the clip catch interlocking and irreversibly retaining the piston in the activated position, whereby the second end of the piston occludes the fluid pathway.
