Abstract
Abstract An arterial anchor bandage has a transparent bulbous shield which protrudes above a tri-lobed outer covering layer. The bulbous shield has an opening sized to receive the tube from an arterial catheter and has a generally elliptical cross section. A flange at the bottom of the shield prevents the shield from cutting into the skin of the patient. An absorbent layer between the shield and the skin surface provides a wicking function to remove fluids from the area where the arterial catheter enters the patient. A protective sheet covers an adhesive surface of the outer covering layer so that the arterial anchor bandage can be applied as a unit assembly once the catheter has been inserted. Various features of the structure permit its application very close to joints in a patient's anatomy.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
175 words
An arterial anchor bandage comprising: a bulbous element having a generally planar flange defining an oblong footprint, with a central opening and a peripheral edge fashioned from a transparent material, including a general circular opening at a predetermined elevation above the footprint sized to receive a cannula tube, a slit extending from the opening through the flange, and the flange defining an acute angle with the bulbous element at the slit; a layer of absorbent material under the flange having an opening generally coextensive with the central opening, and extending laterally beyond the flange; an outer covering having an adhesive surface and a cutout larger than the central opening but smaller than the peripheral edge of the flange, the bulbous element being received in the cutout and so that the flange is adhesively bonded to the outer covering, and the absorbent layer being adhesively bonded to the outer covering outside the peripheral edge of the flange; and a protective layer coextensive with the outer covering, releasable from the adhesive surface to expose the adhesive surface.
Claim 2
Dependent Claim
175 words
An arterial anchor bandage comprising: a bulbous element having a generally planar flange defining an oblong footprint, with a central opening and a peripheral edge fashioned from a transparent material, including a general circular opening at a predetermined elevation above the footprint sized to receive a cannula tube, a slit extending from the opening through the flange, and the flange defining an acute angle with the bulbous element at the slit; a layer of absorbent material under the flange having an opening generally coextensive with the central opening, and extending laterally beyond the flange; an outer covering having an adhesive surface and a cutout larger than the central opening but smaller than the peripheral edge of the flange, the bulbous element being received in the cutout and so that the flange is adhesively bonded to the outer covering, and the absorbent layer being adhesively bonded to the outer covering outside the peripheral edge of the flange; and a protective layer coextensive with the outer covering, releasable from the adhesive surface to expose the adhesive surface.
Claim 3
Dependent Claim
30 words
The arterial anchor bandage of claim 1 wherein the bulbous element has an increased thickness adjacent the slit so as to define a locally more rigid area for cannula support.
Claim 4
Dependent Claim
29 words
The arterial anchor bandage of claim 1 wherein the outer covering is recessed adjacent the slit in the bulbous element to permit application near joints of a human body.
Claim 5
Dependent Claim
35 words
The arterial anchor bandage of claim 3 wherein the outer covering includes a pair of lateral wings, each wing extending laterally in the direction transverse to the bulbous element so as to provide secure support.
Claim 6
Dependent Claim
21 words
The arterial anchor bandage of claim 1 wherein the outer covering includes means for permitting air to traverse the outer covering.
Claim 7
Dependent Claim
40 words
The arterial anchor bandage of claim 1 wherein the bulbous element, in vertical cross section, is generally elliptical with the major axis in general alignment with the circular opening to reduce optical distortion of the central opening of the footprint.
Claim 8
Dependent Claim
18 words
The arterial anchor bandage of claim 1 further including means for holding a tube connectable with a catheter.
