A device, system, kit, and method for managing the passage of fluid through an opening in the body of a patient that includes a fluid-containment receptacle including a collapsible sidewall, the fluid-containment receptacle having a first receptacle opening and a second receptacle opening positioned at opposite ends of the sidewall, the fluid-containment receptacle. The device also including a first flange extending radially outward from the sidewall and positioned at or adjacent to the first receptacle opening and a second flange extending radially outward from the sidewall at or adjacent to the second receptacle opening. The device is configured to be applied to the opening in the body of the patient such that the first opening and the first flange contact the body of the patient and form a fluid barrier around the opening.

Disclosed is a pliable skin barrier ring adapted for placement in a skin fold or crease located around a stoma of a user. The pliable barrier ring includes a first layer of a relatively harder adhesive material having a proximal surface and a distal surface. The pliable barrier ring further includes a second layer of relatively softer adhesive material provided at least on the proximal surface of the first layer of adhesive material. The first adhesive layer includes a relatively thicker bulk portion located in a central portion of the ring, and a relatively thinner flange portion extending radially inwards from an outer peripheral edge of the ring and transitioning into the bulk portion. The relatively thicker bulk portion provides a proximally projecting expanded shape to the central portion of the ring.

Certain embodiments of the present application relate to an adjustable ostomy wafer system including an ostomy wafer and an insert ring 100. The ostomy wafer includes an adjustable layer with an effluent opening through which effluent flows, and the adjustable layer has a body-facing side and a non-body-facing side. The insert ring 100 is capable of providing or increasing convexity of the adjustable layer when the insert ring 100 is pressed against the non-body-facing side of the adjustable layer.

A method and a device are described for an ostomy base plate having a storage configuration as delivered to a user and a use configuration as applied to skin of the user. In the storage configuration, a proximal side of the ostomy base plate is substantially convex, and in the use configuration, the proximal side of the ostomy base plate is substantially concave.

An ostomy base plate has undulations formed in an adhesive composition to provide the adhesive composition with valleys of relatively lower adhesive thickness and ridges of relatively higher adhesive thickness.

An ostomy appliance according to certain embodiments generally includes a pouch, an adhesive collar, and a release liner. The adhesive collar includes an adhesive to secure the pouch around a stoma. The release liner is configured to allow manipulation of the adhesive through the pouch. The adhesive collar is attached to the pouch around a stomal opening for fitting around the stoma, and the adhesive in the adhesive collar is attached to an inside of the pouch.

A convex ostomy barrier assembly for attaching an ostomy appliance to a peristomal skin surrounding a stoma includes a skin barrier, an inlet opening defined in the skin barrier for receiving the stoma, and a convexity adjusting device. The convexity adjusting device is configured to provide a convexity to the skin barrier and to automatically adjust the convexity according to the topography of user's peristomal skin as the convex ostomy barrier assembly is applied to a user. The convexity adjusting device is configured to provide a localized and customized adjustment of at least one characteristic of the convexity.

An ostomy barrier appliance for attaching an ostomy appliance to peristomal skin surrounding a stoma is provided. The ostomy barrier appliance includes a skin barrier, an inlet opening for receiving a stoma, and a convexity adjusting device arranged adjacent the skin barrier. The convexity adjusting device is configured to adjust the convexity of the skin barrier.

Ostomy wafers, ostomy devices incorporating ostomy wafers, and methods of applying ostomy wafers and ostomy devices are disclosed herein. An ostomy wafer may include an external layer and a convex surface coupled to the external layer. An ostomy device may include an ostomy pouch and an ostomy wafer coupled to the ostomy pouch that includes an external layer and a convex surface coupled to the external layer.

A convex ostomy barrier assembly for attaching an ostomy appliance to a peristomal skin surrounding a stoma includes a skin barrier, an inlet opening defined in the skin barrier for receiving the stoma, and a convexity adjusting device. The convexity adjusting device includes a convex insert and an inflatable bladder, wherein the convex insert is configured to provide a convexity to the skin barrier and the inflatable bladder is configured to adjust at least one characteristic of the convexity.
