Catheter anchoring system
First Claim
1. An anchoring system for securing a catheterization device to the body of a patient, said anchoring system comprising a clamp configured to releasably engage a portion of the catheterization device and a retainer connected to an adhesive layer for secure attachment to the body of the patient, said clamp and retainer including corresponding coupling structure which releasably engage to secure said clamp to said retainer, said coupling structure comprising at least one hole which receives a corresponding post, said post includes a flared end which has a size larger than at least a portion of said holesaid hole having a first opening which is larger than said flared end of said post, and a second opening which is smaller than said flared end of said post.

Abstract
An anchoring system for a central line catheter or other similar catheter or fluid lines provides convenient installation and release with a minimum of procedures and no pain or discomfort to the patient. The anchoring system includes a self-adhesive anchoring pad for secure mounting on the patient and an associated retainer. The retainer includes slotted openings to receive downwardly extending posts formed on the underside of lateral wings of a box clamp. The ends of the posts can be easily inserted into a large diameter central openings of the retainer holes and then slid horizontally to allow frictional or snap fit engagement and retention between the necks of the posts and the lateral slots or holes formed in the retainer. In this position, the ends of the posts are captured with a hollow within the retainer and beneath the lateral slots, and the box clamp and retainer thus are releasably locked together. The opposite sequence is followed for removal of the box clamp and catheter combination. A soft, pliable wing clamp also can be used in connection with the box clamp to retain the catheter and/or associated tubing within the box clamp.

17. A method for attaching a catheterization device to a body of a patient, comprising the steps of:
-
providing a retainer coupled to an adhesive member; providing a clamp configured to engage a portion of the catheterization device; placing said adhesive member on the patient'"'"'s body to secure the retainer thereon; engaging said clamp with a portion of the catheterization device; connecting said clamp to said retainer in a releasable manner; and releasing said clamp from said retainer in a manner which permits the clamp to be later reconnected to the retainer. - View Dependent Claims (18, 19, 20)

- 21. An anchoring system for securing a medical device to the body of a patient, said medical device including a cylindrical portion, said anchoring system comprising a clamp configured to releasably engage the cylindrical portion of the medical device and a retainer connected to an adhesive layer, said clamp and retainer comprising corresponding first and second members which releasably interconnect to couple together said clamp and retainer, said first member being movable relative to said second member and in a direction generally parallel to said adhesive layer from a first position in which said first and second members are disengaged to a second position in which said first and second members are engaged.
- 28. An anchoring system for securing a medical device to the body of a patient, the medical device having an elongated portion which defines an axis, said anchoring system comprising a clamp configured to engage the elongated portion of the medical device, and a retainer coupled to an adhesive layer which adheres to the body of the patient, said clamp and retainer having corresponding coupling structures that engage to secure said clamp to said retainer, said coupling structure comprising an aperture having a major diameter lying generally perpendicular to the axis of the elongated portion engaged by the clamp, and a minor diameter lying generally parallel to the axis, said aperture being positioned to receive a corresponding post of said coupling structure, said post having a flared end of a size larger than at least a portion of said aperture.
