1. An anchor system for securing to a skin opening, comprising:
an anchor device configured to releasably secure to an external portion of a catheter while another portion of the catheter occupies a skin opening, the anchor device including:
a retainer base comprising a flexible hinge region that defines a central fold axis and has an upwardly facing channel to frictionally engage with the external portion of a catheter, and first and second subcutaneous anchors fixedly mounted on opposite sides of the central fold axis and extending distally from a distal end of the retainer base to anchor in the skin opening, each of the first and second subcutaneous anchors comprising: a longitudinal shaft portion that extends in a distal direction to a position that is distal of the distal end of the retainer base, and a flexible tine configured to deploy in a subcutaneous region to secure the retainer base relative to the skin opening;
a cap releasably mountable to the retainer base over the upwardly facing channel of the flexible hinge region so as to define a grip channel between the cap and the upwardly facing channel of the retainer base for frictional engagement with the external portion of the catheter
wherein each of the first and second subcutaneous anchors is pivotable about the central fold axis of the flexible hinge region so as to adjust both the flexible tine of the first subcutaneous anchor and the flexible tine of the second subcutaneous anchor from a deployed configuration to a removal configuration.
