DETAILED DESCRIPTION

[0026] The matters exemplified in this description are provided to assist in a comprehensive understanding of various exemplary embodiments disclosed with reference to the accompanying figures. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the exemplary embodiments described herein can be made without departing from the spirit and scope of the claimed invention. Descriptions of well-known functions and constructions are omitted for clarity and conciseness. Moreover, as used herein, the singular may be interpreted in the plural, and alternately, any term in the plural may be interpreted to be in the singular.

[0027] The present invention sets forth an ostomy appliance and/or system that may include one or more of several features, including but not limited to the following: having a straight edge or substantially straight edge of a flange that may be aligned with a patient's or user's skin crease, roll, or fold.

[0028] In accordance with some embodiments (and as discussed in greater detail below), the design may comprise a straight edge or substantially straight edge as part of an ostomy faceplate or appliance. The straight or substantially straight end of the faceplate or appliance may include a tapered end, may comprise different adhesive than the overall appliance or faceplate, and/or may be made from or comprised of a different material.

[0029] The present document uses the term “flange,” which is intended to refer to a physical component that assists in the connection between a faceplate or appliance and a bag or pouch. Note that while the present invention generally illustrates faceplates and appliances as being separate from the bag or pouch, one-piece appliance-and-pouch devices are also contemplated. In such combined devices, there is still a flange that provides connection between the bag and the faceplate or appliance—though in combined devices the bag or pouch may not be removable.

[0030] With reference to FIG. 1, a substantially “D” shaped ostomy appliance is illustrated. The appliance in FIG. 1 comprises a material 110 that is generally attached to, or adhered to, a patient, and may comprise a flexible and comfortable material, such as flexible wound dressing (for example, DUODERM®—manufactured for ConvaTec). Flange 120 may comprise a more rigid (though still flexible and bendable) ring that may encircle an orifice 130. During use, the orifice 130 may be aligned with a user's or patient's stoma. A bag or pouch may be attach to the flange 120 to receive effluent from the stoma.

[0031] Note that the present invention provides a means to locate an ostomy faceplate or appliance close to user's skin creases, rolls, or folds. The general shape of the outside portion of the appliance can be of any variety, as at least one goal of the invention is to get as close to the crease, roll, or fold by positioning the straight or substantially straight edge of the flange proximate to the crease, roll, or fold.

[0032] Accordingly, and with reference to FIG. 2, the outer material 210 may be in any shape. Indeed, it is known that nurses, patients, and users often cut or trim this outer material to a desirable shape or size. However, round flanges on ostomies in the prior art prevent location of the appliance directly proximate to a crease, roll, or fold.

[0033] FIG. 2 shows an appliance or faceplate with a substantially D-shaped flange 220 mounted on a square or rectangular material 210. Again, an orifice 230 is positioned inside the flange 220 to receive a stoma.

[0034] The present invention is intended to address a need in the art of different shaped ostomy appliances or faceplates to accommodate different body types and needs. For example, a user may have a centerline incision due to certain medical procedures (such as, but not limited to, emergency trauma surgery). The user may also have creases, rolls, or folds. To accommodate the centerline wound (and any negative pressure wound device that may be used to assist in closing and healing of the centerline incision) and a user's body type that may include creases, rolls, or folds, there may be more than one substantially straight edge to the flange on the ostomy appliance or faceplate. With reference to FIGS. 3 and 4, a pie-piece shaped flange 320, 420 may be mounted on a softer material 310, 410 which may be of different shapes. The flange 320, 420, may again encircle an orifice 330, 430 for receiving a stoma.

[0035] Similar to FIGS. 3 and 4, FIGS. 5 and 6 present an ostomy appliance with a substantially square or rectangular shaped flange 520, 620, mounted on a softer material 510, 610. Note that it is contemplated by the present invention that the orifice for the stoma may not be centrally located, but may be positioned asymmetrically within the flange. With reference to FIG. 6, the orifice 630 is shown to be positioned in a corner of the flange 620. A user may cut the orifice in the faceplate or appliance to position the orifice in a position necessary to receive a stoma, while aligning the straight or substantially straight edges of the flange with a user's creases, rolls, folds, incisions, wounds, etc.

[0036] The overall shape of the flange can vary, provided that there is at least one straight or substantially straight edge. For example, FIG. 7 illustrates an ostomy appliance with a first material 710, a flange 720, and an orifice 730, in which the flange 720 has several straight and a curved edge. FIG. 8 shows a triangular shaped appliance, comprising a triangular shaped material 810 and a triangular shaped flange 820, including an orifice 830.

[0037] Note that while the present invention continually discusses straight or substantially straight edges to the flange, it is understood that some creases, rolls, or folds, may be in the shape of an arc. For example, a fold due to an enlarged abdomen may appear linear, but three-dimensionally may have a curve to it. FIG. 9 shows an oval-shaped ostomy appliance 910 with an oval-shaped flange 920. Again, an orifice 930 is positioned within the flange 920.

[0038] FIG. 10 shows a rectangular shaped ostomy appliance 1010 and flange 1020, with substantially parallel, substantially straight edges connected by rounded corners. Again, orifice 1030 is positioned within the flange 1020.

[0039] FIGS. 11 and 12 illustrate an ostomy appliance and flange that may have a more complex shape. FIGS. 11 and 12 illustrates an ostomy appliance 1110, 1210 with a flange 1120, 1220 within which is an orifice 1130, 1230. The overall shape of the flange 1120, 1220 is substantially “T” shaped (though illustrated as an inverted “T”).

[0040] FIGS. 13-16 illustrate the point that a “substantially straight edge” may include angle (such as in FIGS. 13-15) or curves (such as in FIG. 16). Each appliance includes a first material 1310, 1410, 1510, 1610, a flange 1320, 1420, 1520, 1620, and an orifice 1330, 1430, 1530, 1630. In FIG. 13, the substantially straight edge of the flange 1320 may comprise multiple angled lines. In FIG. 14, the substantially straight edge of the flange 1420 may comprise an angle extending away from the inside of the flange 1420, while in FIG. 15 the substantially straight edge may comprise an angle extending toward the inside of the flange 1520. FIG. 16 illustrates an appliance 1610 with a flange 1630 with a substantially straight edge comprising a series of curves or arcs.

[0041] In other words, each embodiment of the ostomy appliance may comprise a flange that has an edge configured to be placed or disposed along an incision, roll, crease, or fold, thereby providing significant advantages over an ostomy appliance with a traditionally round flange.

[0042] It will be understood that the specific embodiments of the present invention shown and described herein are exemplary only. Numerous variations, changes, substitutions and equivalents will now occur to those skilled in the art without departing from the scope of the invention. Accordingly, it is intended that all subject matter described herein and shown in the accompanying drawings be regarded as illustrative only, and not in a limiting sense.
