1. A catheter anchor device for use with a catheter which is inserted into a patient at a catheter insertion site for minimizing movement of the catheter that could result in pressure, discomfort, or tearing at the catheter insertion site, the catheter anchor device configured to automatically deploy one or more sutures to quickly and efficiently secure the catheter, the anchor device comprising:
an adhesive layer configured to be secured to the skin of the patient proximate the catheter insertion site and having a center aperture surrounding the catheter insertion site that allows access to the catheter insertion site and permits a practitioner to view and clean the catheter insertion site without manipulating or removing the adhesive layer;
at least one semi-rigid securement mechanism coupled to the adhesive layer and having one or more recesses formed therein, the at least one semi-rigid securement mechanism providing access to the center aperture;
one or more sutures positioned within the one or more recesses, the one or more sutures being secured to the at least one semi-rigid securement mechanism; and
a movable member being utilized in connection with the one or more sutures, wherein movement of the movable member automatically deploys the one or more sutures from the one or more recesses and secures the catheter relative to the anchor device.
