A convex ostomy barrier for attaching an ostomy appliance to a peristomal skin surrounding a stoma includes a skin barrier formed from a skin friendly adhesive, an inlet opening for receiving a stoma, and a convex insert system arranged adjacent the skin barrier to provide a convex body-side contour of the convex ostomy barrier. The convex insert system includes a convex insert and a ring, which are configured to be assembled together to form the convex insert system.

An adaptable ostomy base plate having a substantially convex shape for initial engagement with a peristomal skin surface and can be inverted to a substantially concave shape to fittingly engage to a topography of the peristomal skin surface for permanent engagement thereto. The base plate comprises a reinforcement ring arranged on a distal surface of the top film and the inner section of the base plate, being inside the reinforcement ring is provided with undulations defined by a series of concentric ridges and valleys, said series progresses outwardly from the stoma-receiving through-going hole towards the reinforcement ring and at least partly under the reinforcement ring.

Provided herein are controlled evacuation devices, ostomy devices, methods for the manufacture of such devices and the use of such devices.

A mounting assembly for an ostomy appliance is disclosed. The mounting assembly comprises a body flange comprising a flexible plastic member comprising a flange ring, a rim, and first and second loops, and an adhesive skin barrier member. The mounting assembly also comprises an ostomy pouch comprising a proximal sheet having an aperture, a distal sheet, and a pouch ring attached to the proximal sheet, surrounding the aperture, the pouch ring comprising an adhesive coating thereon and third and fourth loops extending radially therefrom. The body flange and ostomy pouch are configured for the third and fourth loops to engage within the pocket of the first and second loops, respectively, the pouch ring to fit around the flange ring, and the rim of the flexible plastic member to contact the adhesive coating on the pouch ring. The adhesive skin barrier member has a multi-petaled outer perimeter.

A multi-petaled mounting member for an ostomy pouch is disclosed. The mounting member comprises a flexible plastic member comprising a central body portion, a surrounding rim, and an outer perimeter, a first double-sided adhesive substrate member comprising a first face, an opposite second face, and an outer perimeter, a second double-sided adhesive substrate member comprising a first face, an opposite second face, and a multi-petaled outer perimeter, and an adhesive skin barrier member comprising a first face, an opposite second face, and a multi-petaled outer perimeter. The perimeters of the first member and the adhesive skin barrier member substantially correspond in size and shape to the perimeters of the flexible plastic member and the second member, respectively. The perimeter of the second member has a size greater than the perimeter of the flexible plastic member and a shape corresponding to 2 to 8 petals extending radially from the second member.

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.

A base plate of an ostomy appliance includes a film, an adhesive disposed on a proximal surface of the film, an annular ring connected to the distal surface of the film, and a release liner removably attached to the adhesive. A stoma-receiving through-going hole is formed through the film and the adhesive and the release liner. A first section of the base plate extends radially from the stoma-receiving through-going hole to a second section of the base plate, and the second section extends radially from the first section to an outermost perimeter edge of the base plate. The base plate is formed to have a heat-set curvature such that a proximal side of the second section is convex and a distal side of the second section is concave relative to the annular ring.

Certain embodiments of the present application relate to an adjustable ostomy wafer system including an ostomy wafer and an insert ring. 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 is capable of providing or increasing convexity of the adjustable layer when the insert ring is pressed against the non-body-facing side of the adjustable layer.

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.

Described herein are support devices, which may include medical support devices. In particular, three-dimensional medical (and non-medical) devices from a single layer of material, typically by stamping or pressing (including cold pressing) a sheet of the material to form rigid and complex 3D shapes capable of use for a variety of medical and non-medical purposes. These support devices typically also include an adhesive material allowing the device to be attached to a subject's skin and/or mounted on a surface (e.g., wall, etc.). In particular, described herein are methods of manufacturing, assembling, and using adhesive support devices.
