Abstract

The invention relates to a carrier system for an object worn on the body, comprising a flexible carrier plaster, which has a flat carrier layer and an adhesive layer, applied to the lower face of said carrier layer, which adhesive layer adheres to the skin of a body part when pressed thereon, the adhesive layer consisting of a pressure-sensitive adhesive, and further comprising, on the upper face of the carrier layer facing away from the skin, a rigid mounting platform. According to this disclosure, a joining region of the mounting platform is permanently joined to the upper face of the carrier layer via a structural adhesive connection that consists of a structural adhesive.

Claims

1. A carrier system for a medical instrument worn on the body, comprising:

a flexible carrier ply comprising a microperforated thermoplastic foil, the microperforations being formed on the lower side of the carrier ply which faces the skin and at least some of the microperforations being conically shaped and arranged with the wider end of the perforations facing the skin;

the carrier ply having on a lower side thereof an adhesive layer comprising a pressure sensitive adhesive that adheres to the skin of a body part by contact pressure, the adhesive layer having a pressure sensitive adhesive application of 80 to 120 g/m², wherein the microperforations are located on an adhesive covered area of the lower side of the carrier ply; and

an assembly platform arranged on an upper side of the carrier ply, wherein the upper side of the carrier ply faces and is attached flatly to a lower joining surface of the assembly platform in a joining region, wherein the joining region is firmly connected to the upper side of the carrier ply via a structural adhesive.

2. The carrier system as claimed in claim 1, wherein the assembly platform has at least one aperture configured for access to the skin.

3. The carrier system of claim 2, wherein the at least one aperture extends through the flexible carrier ply.

4. The carrier system as claimed in claim 1, wherein the carrier ply further comprises a removable release liner.

5. The carrier system as claimed in claim 4, wherein the release liner comprises a projecting tab.

6. The carrier system as claimed in claim 1, wherein the carrier ply has a maximum elastic modulus of less than 10 N/mm².

7. The carrier system as claimed in claim 6, wherein the carrier ply has a maximum elastic modulus of less than 5 N/mm².

8. The carrier system as claimed in claim 1, wherein the adhesive layer has a pressure sensitive adhesive application of 100 to 110 g/m².

9. The carrier system as claimed in claim 1, wherein the adhesive layer is formed by a pressure sensitive adhesive based on acrylate, silicone, rubber, thermoplastic elastomer, hydrogel, polyurethane, polysiloxane, vinyl acetate or mixtures thereof.

10. The carrier system as claimed in claim 1, wherein the carrier ply and/or the adhesive layer has an MVTR value of more than 400 g/m² of water vapor permeability in 24 h.

11. The carrier system as claimed in claim 1, wherein the structural adhesive includes cyanoacrylate, epoxy or polyurethane.

12. The carrier system as claimed in claim 1, wherein the pressure sensitive adhesive and the structural adhesive have a biocompatible composition.

13. The carrier system as claimed in claim 1, wherein the assembly platform is formed by a plastic molding.

14. The carrier system as claimed in claim 13, wherein the assembly platform is formed of polycarbonate.

15. The carrier system of claim 1, wherein the microperforations are wider on the lower side of the carrier ply.

16. The carrier system of claim 1, wherein the microperforations have selectively different perforation geometries.

17. The carrier system as claimed in claim 1, wherein the adhesive covered area of the lower side of the carrier ply is flat.

18. The carrier system of claim 1, wherein the assembly platform is rigid.

19. The carrier system of claim 1, wherein the assembly platform comprises a plate-type plastic molding.
