| 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 that allows access
to the catheter insertion site and permits a practitioner to view and clean the catheter insertion site;
a stationary base secured to the adhesive layer;
a rotatable ring circumscribing the stationary base such that the rotatable outer ring can be rotated by the user relative
to the stationary base; and
one or more sutures having a stowage position, wherein when the sutures are in the stowage position the sutures are positioned
between the stationary base and the rotatable ring, wherein the one or more sutures are operably coupled to the rotatable
ring such that actuation of the rotatable ring automatically deploys the one or more sutures from the stowage position to
secure the catheter relative to the rotatable ring; and
an O-ring that secures the sutures between the stationary base and the rotatable ring before deployment of the sutures while
allowing deployment of the sutures upon actuation of the rotatable ring.
