Anchoring system for a catheter
First Claim
1. An anchoring system for securing a urinary drainage catheter or other medical article to a body of a patient, comprising:
- a catheter comprising a relatively soft tube defining a lumen and a relatively rigid connector fitting, the connector fitting being disposed within the lumen of the tube;
an anchor pad having an upper surface and a lower surface, at least a portion of the lower surface having adhesive for contacting a patient'"'"'s skin;
a unitary retainer permanently and rotatably attached to the upper surface of the anchor pad and comprising a base and a strap, the strap being integrally formed with the base, the strap being wrapped around the catheter distal to a Y-site of the catheter, the retainer including a through-hole;
a mounting post formed in unity to include a mounting base, a pedestal and a cap, the mounting base attaching to the anchor pad, and the pedestal and the cap connecting the mounting base and the retainer by coupling with the retainer via the through-hole, the retainer being rotatable relative to the anchor pad, wherein the pedestal and the cap include a slot extending through the cap and at least partially through the pedestal;
the retainer having an interengaging structure which secures the strap such that the catheter is secured to the base, the interengaging structure including a latch disposed on the base and being separated from the strap; and
the retainer and catheter contacting each other over a contact area to provide frictional interaction therebetween, said frictional interaction sufficient to inhibit longitudinal movement of the catheter relative to the retainer.

Abstract
An anchoring system secures a catheter to the body of a patient and arrests axial movement of the catheter without meaningfully impairing fluid flow through the catheter. The anchoring system includes an anchor pad that adheres to the patient'"'"'s skin and supports a retainer. The retainer includes interengaging structure that moves the retainer between an open and a closed position. When in the open position, the retainer can receive a portion of the catheter and be subsequently moved to the closed position. Advantageously, the interengaging structure allows the retainer to receive catheters of various sizes. The retainer may further include one or more retention mechanisms to further inhibit axial movement of the catheter relative to the retainer when the catheter is secured therein. The anchoring system may include a mount that allows the retainer to rotate relative to the anchor pad.

14. A retainer for securing a urinary drainage catheter or other medical article to a body of a patient, comprising:
-
a catheter comprising a relatively soft tube defining a lumen and a relatively rigid connector fitting, the connector fitting being disposed within the lumen of the tube; an anchor pad having an upper surface and a lower surface, at least a portion of the lower surface having adhesive for contacting a patient'"'"'s skin; a base permanently and rotatably attached to the upper surface of the anchor pad, the base including a through-hole; a strap integrally formed together with the base as a unitary retainer and being wrapped around the catheter distal to a Y-site of the catheter; a mounting post formed in unity to include a mounting base, a pedestal and a cap, the mounting base attaching to the anchor pad, and the pedestal and the cap connecting the mounting base and the base by coupling with the base via the through-hole, the base being rotatable relative to the anchor pad, wherein the pedestal and the cap include a slot extending through the cap and at least partially through the pedestal; and an interengaging structure which secures the strap such that the catheter is secured to the base, the interengaging structure including a latch disposed on the base and being separated from the strap, wherein a contact area provides frictional interaction with the catheter, the frictional interaction sufficient to inhibit longitudinal movement of the catheter relative to the retainer at least when the strap is secured to the interengaging structure. - View Dependent Claims (15, 16, 17, 18)

19. An anchoring system for securing a catheter to a body of a patient, comprising:
-
a catheter comprising a relatively soft tube defining a lumen and a relatively rigid connector fitting, the connector fitting being disposed within the lumen of the tube; an anchor pad having an upper surface and a lower surface, at least a portion of the lower surface having adhesive to attach the anchor pad to the body of the patient; a retainer permanently mounted to the upper surface of the anchor pad and being capable of receiving a portion of the catheter, the retainer comprising a base and a strap and including a through-hole, the strap and base being integrally formed, the base having a contact area, at least a portion of the strap being movable relative to the base so as to move between an open position and a closed position and being wrapped around the catheter distal to a Y-site of the catheter; a mounting post formed in unity to include a mounting base, a pedestal and a cap, the mounting base attaching to the anchor pad, and the pedestal and the cap connecting the mounting base and the retainer by coupling with the retainer via the through-hole, the retainer being rotatable relative to the anchor pad, wherein the pedestal is flared at a bottom portion; and an interengaging structure configured to secure the strap when in the closed position such that the catheter is secured to the retainer, the interengaging structure including a latch disposed on the base and being separate from the strap, the retainer and catheter contact each other over at least a portion of the contact area to provide frictional interaction therebetween, the frictional interaction being sufficient to inhibit longitudinal movement of the catheter relative to the retainer at least when the strap is secured by the interengaging structure. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)
