| 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, displacement, 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 removal of the adhesive layer;
a rotatable ring secured to the adhesive layer while allowing access to the center aperture, the rotatable ring being actuatable
by the user to secure the catheter relative to the catheter anchor device;
one or more sutures coupled to the rotatable ring such that actuation of the rotatable ring actuates the one or more sutures
to secure the catheter relative to the rotatable ring; and
a ratchet mechanism utilized in connection with the rotatable ring, the ratchet mechanism allowing movement of the rotatable
ring in a first direction while securing the rotational position of the rotatable ring against movement in a second direction.
