Collecting bag
First Claim
1. A flange for a medical collecting bag comprising an inner rim delimiting an aperture allowing bodily fluids or exudates to enter the bag, said flange having a central area encircling the aperture which area has a predetermined pattern of weakening lines such that 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, said weakening pattern being in the form of punched or cut dots, slots or interrupted rectilinear or curved lines.

Abstract
A flange for a medical collecting bag having an aperture allowing bodily fluids or exudates to enter the bag. The flange has an inner rim delimiting the aperture therein, and a central area encircling the aperture, which area has a predetermined weakening line pattern. 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 which 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, as well as a complete removal of the bag flange when substituting the bag.

- 6. A medical appliance comprising a body side member having 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 a separately exchangeable collecting bag secured to the body side member for collecting fluids or excretions, said flange having an inner rim defining the aperture therein and a central area encircling the aperture which area has a predetermined pattern of weakening lines such that the force needed for removing the bag flange from skin is smaller than the force needed for breaking the weakening lines, said weakening pattern being in the form of punched or cut dots, slots or interrupted rectilinear or curved lines.
- 7. A medical collecting bag comprising a bag flange having an aperture allowing bodily fluids or exudates to enter the bag, the bag including a coupling element for releasable coupling and sealing to a second corresponding coupling element fixedly connected to a body side member which has 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 bag, said bag flange having an inner rim defining the aperture therein and a central area encircling the aperture and having a predetermined pattern of weakening lines, the force needed for removing the bag flange from the body side member being smaller than the force needed for breaking the weakening lines, and said weakening pattern being in the form of punched or cut dots, slots or interrupted rectilinear or curved lines.
- 9. A medical appliance comprising a body side member having 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 with an aperture allowing bodily fluids or exudates to enter the appliance, said body side member including a first coupling element being fixedly connected to the body side member and the collecting bag including a corresponding second coupling element adapted for releasable coupling and sealing to the body side member, said bag flange having an inner rim defining the aperture therein and a central area with a predetermined pattern of weakening lines, the force needed for removing the bag flange from the body side member being smaller than the force needed for breaking the weakening lines, and the weakening pattern being in the form of punched or cut dots, slots or interrupted rectilinear or curved lines.
