Catheter affixing and anchoring pad and method of use
First Claim
1. An apparatus for affixing and anchoring a catheter to the body of a patient, the apparatus comprising:
- a pad having a first surface, a second surface and a peripheral edge;
a passageway extending from said peripheral edge of the pad, through a portion of the pad between said first and second surfaces and terminating in an opening located within the pad and away from the peripheral edge thereof, the size and configuration of the passageway being such that the passageway can snugly receive a portion of said catheter therein;
an open channel formed in the first surface of the pad and communicating with the passageway through said opening, said open channel extending from said opening to the peripheral edge of the pad, the size and configuration of the channel being such that the channel can receive therein a portion of the catheter extending from the opening formed by the passageway; and
wherein the passageway and the open channel are configured and positioned so as to permit substantially unrestricted fluid flow through said catheter when portions of said catheter are received therein.

Abstract
A catheter affixing and anchoring device including a unitary thermoplastic elastomer pad through which a catheter clasping tunnel is bored to lead a catheter to and through a directional channel. The channel affixes the catheter in a preferred configuration preparatory to anchoring of the device and the catheter assembly to the body of a medical patient by means of a simple procedure and in a manner which allows for easy and repeated cleaning of the insertion site with limited disturbance to the catheter assembly or underlying body tissues. This invention is particularly well suited to use in connection with parenteral infusion, drainage of bodily fluid accumulations and administration of medicaments in liquid form directly to various parts of the body. This invention may also advantageously be used in other applications requiring the infusion of fluids, such as, for example, hyperalimentation.

4. An apparatus for affixing and anchoring a catheter to the body of a patient, the apparatus comprising:
-
a pad having a substantially planar first surface, a substantially planar second surface and a peripheral edge, said first and second surfaces of the pad being substantially the same size and shape and lying substantially parallel to one another; a passageway extending from said peripheral edge of the pad, through a portion of the pad between said first and second surfaces and terminating in an opening located within the pad and away from the peripheral edge thereof, the size and the configuration of the passageway being such that the passageway can snugly receive a portion of said catheter therein; at least one open channel formed in the first surface of the pad and communicating with the passageway through said opening, said open channel extending from said opening to the peripheral edge of the pad, the size and configuration of the channel being such that the channel can receive therein a portion of the catheter extending from the opening formed by the passageway, the depth of the open channel being such that said portion of the catheter received in the channel lies substantially entirely within the pad between said first and second surfaces thereof; and wherein the passageway and the open channel are configured and positioned so as to permit substantially unrestricted fluid flow through said catheter when portions of said catheter are received therein. - View Dependent Claims (5, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

6. An apparatus for affixing and anchoring a catheter to the body of a patient as defined in claim wherein peripheral edge of the pad has a substantially rounded shape.
-
19. A method for affixing and anchoring a catheter to the body of a patient, the method comprising the steps of:
-
inserting a portion of the catheter through a passageway which extends from a peripheral edge of a pad through a portion of the pad and terminates in an opening located within the pad and away from the peripheral edge thereof, the size and configuration of the passageway being such that the passageway snugly receives said portion of the catheter therein; placing a portion of the catheter extending from the opening formed by said passageway in an open channel formed in a first surface of the pad and communicating with the passageway through said opening, said open channel extending from said opening to the peripheral edge of the pad, wherein the passageway and the open channel are configured and positioned so as to permit substantially unrestricted fluid flow through said catheter when portions of said catheter are received therein, and the depth of the open channel being such that said portion of the catheter received in the channel lies substantially entirely within the pad; and affixing the pad to the body of said patient by means other than securing straps.
