Abstract

A flange for a medical collecting bag having an aperture allowing bodily fluids or exudates to enter the bag, wherein the flange has an inner rim delimiting the aperture therein, and wherein the flange has a central area encircling the aperture which area has a predetermined weakening line pattern wherein the force needed for removing the bag flange from the skin or a body side member is smaller than the force needed for breaking the weakening lines enables a simple gradual enlargement of the aperture of an ostomy device for adaptation of the aperture to the size of the stoma or for adaptation of the aperture to the size of a wound and a complete removal of the bag flange when substituting the bag.

Claims

1. A flange for a medical collecting bag having an aperture allowing bodily fluids or exudates to enter the bag, wherein the flange has an inner rim delimiting the aperture therein, wherein the flange has a central area encircling the aperture which area has a predetermined weakening line pattern wherein the force needed for removing the bag flange from the skin or a body side member is smaller than the force needed for breaking the weakening lines, and wherein the weakening pattern is in the form of punched or cut dots, slots or interrupted rectilinear or curved lines.

2. A flange as claimed in claim 1, wherein the weakening pattern is in the form of an interrupted helical line starting from the inner rim of the flange.

3. A flange as claimed in claim 1, wherein the weakening pattern is in the form of a number of interrupted essentially concentric lines surrounding the aperture of the second flange.

4. A flange as claimed in claim 1 wherein the weakening pattern is in the form of a combination of helical or concentric lines and radial lines.

5. A flange as claimed in claim 1 wherein the weakening pattern is in the form of concentric lines and wherein the weakening pattern has at least one interruption in a radial zone from the aperture for receiving the stoma.

6. A medical appliance comprising a body side member comprising a flange in the form of an adhesive wafer for securing the appliance to a patient'"'"'s skin, said wafer having an aperture allowing bodily fluids or exudates to enter the appliance, and an optionally separately exchangeable collecting bag secured to the body side member for collecting fluids or excretions, wherein the flange has an inner rim defining the aperture therein and a central area encircling the aperture which area has a predetermined weakening pattern wherein the force needed for removing the bag flange from skin is smaller than the force needed for breaking the weakening lines, and wherein the weakening pattern is in the form of punched or cut dots, slots or interrupted rectilinear or curved lines.

8. An collecting bag as claimed in claim 6 or 7 wherein the central area having a predetermined weakening line pattern does not show adhesive properties.

10. An appliance or bag according to any of claims 6-9 in the form of an ostomy appliance or bag or a wound care appliance or bag.

11. An appliance or bag as claimed in claim 10 in the form of an ostomy appliance or bag.

7. An medical collecting bag having a bag flange having an aperture allowing bodily fluids or exudates to enter the appliance, the bag comprising coupling means for releasable coupling and sealing to corresponding coupling means fixedly connected to a body side member comprising an adhesive wafer for securing the body side member to a patient'"'"'s skin, said wafer having an aperture allowing bodily fluids or exudates to enter the appliance, wherein the bag flange has an inner rim defining the aperture therein, wherein the flange has a central area encircling the aperture and having a predetermined weakening line pattern wherein the force needed for removing the bag flange from the body side member is smaller than the force needed for breaking the weakening lines, and wherein the weakening pattern is in the form of punched or cut dots, slots or interrupted rectilinear or curved lines.

9. A medical appliance comprising a body side member comprising an adhesive wafer for securing the appliance to a patient'"'"'s skin, said wafer having an aperture allowing bodily fluids or exudates to enter the appliance, and a separately exchangeable collecting bag having a bag flange having an aperture allowing bodily fluids or exudates to enter the appliance, wherein the body side member comprises first coupling means being fixedly connected to the body side member and the collecting bag comprises corresponding second coupling means adapted for releasable coupling and sealing to the body side member, wherein the bag flange has an inner rim defining the aperture therein and a central area which area has a predetermined weakening line pattern wherein the force needed for removing the bag flange from the body side member is smaller than the force needed for breaking the weakening lines, and wherein the weakening pattern is in the form of punched or cut dots, slots or interrupted rectilinear or curved lines.
