Abstract
An ostomy device including a collecting bag and a base plate with an adhesive plate for being fastened on the user, the base plate having a stomal opening and a first flange for repeated and removable adhesive connection to a coupling element on the collecting bag which has a second flange. The adhesive connection is provided by at least one layer of an adhesive. Furthermore, the device includes a further flexible layer placed between the adhesive layer and the one of the first and second flanges having the lower tensile strength, the flexible layer having a yield strength exceeding the adhesive strength of the adhesive layer.
Claims20
An ostomy device comprising:
- a body side member with an adhesive plate for being fastened on the user, said body side member having an opening for receiving an ostomy and a first flange manufactured from a material with a first tensile strength;
- a collecting bag including a coupling element having a second flange manufactured from a material with a second tensile strength, said first flange being configured for repeated and removable adhesive connection to said coupling element;
- and
- a flexible layer bonded to an outer surface of said second flange and an adhesive layer affixed to said flexible layer so that said flexible layer is sandwiched between the adhesive layer and the second flange, said bond between the outer surface of the second flange and the flexible layer being stronger than a connection between the first flange and the adhesive layer of said collecting bag coupling element,
- said flexible layer having a yield strength exceeding an adhesive strength of the adhesive layer.
An ostomy collecting bag for use with a separate base plate adhered to the skin of a user, the ostomy collecting bag comprising:
- a coupling element having a flange for removable and adhesive connection to another flange on the base plate, a flexible layer bonded to an outer surface of said coupling element flange, and an adhesive layer affixed to said flexible layer so that said flexible layer is sandwiched between the adhesive layer and the coupling element flange, said flexible layer having a yield strength exceeding an adhesive strength of the adhesive layer, and a strength of the bond between said flexible layer and said coupling element flange also exceeding the adhesive strength of said adhesive layer.
An ostomy device comprising:
- a base plate with an adhesive plate for being fastened on the user, said base plate having an opening for receiving an ostomy and a first flange manufactured from a material with a first tensile strength;
- a collecting bag including a coupling element having a second flange manufactured from a material with a second tensile strength lower than said first tensile strength, said first flange being configured for repeated and removable adhesive connection to said coupling element;
- a flexible layer bonded to an outer surface of said second flange;
- and
- a layer of adhesive affixed to an outer surface of said flexible layer and having an adhesive strength to provide said adhesive connection between said first flange and said coupling element, said flexible layer having a yield strength exceeding the adhesive strength of the adhesive layer.
