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 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; 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 carrier ply further comprises a removable release liner.

3. The carrier system as claimed in claim 2, wherein the release liner comprises a projecting tab.

4. The carrier system as claimed in claim 1, wherein the carrier ply is formed from one or more of a foil material, textile material, and a foam.

5. The carrier system as claimed in claim 1, wherein the carrier ply comprises microperforated thermoplastic foil.

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.

19. The method as claimed in claim 12, further comprising using the carrier system for at least one application from the following group:

sensorially monitoring and/or capturing a body parameter;

administering active ingredients;

providing a body entry port or body exit port;

wearing body jewelry.

20. The method of claim 19, wherein the carrier system is used for administering insulin to or through the skin.

15. A method of producing a carrier system for a medical instrument worn on the body, the method comprising the following steps:

providing a carrier plaster as a die-cut part, the carrier plaster including a carrier ply, an adhesive layer and a release liner, wherein the adhesive layer has a pressure sensitive adhesive application of 80 to 120 g/m²;

applying a structural adhesive as an adhesive bead to a joining region of an assembly platform; and

contacting the joining region with an upper side of the carrier plaster to form a structural adhesive bond, wherein the upper side of the carrier ply faces and attaches flatly to a lower joining area of the assembly platform.

16. The method as claimed in claim 15, further comprising pressing the carrier plaster against the assembly platform during curing of the structural adhesive.

17. The method as claimed in claim 15, wherein the structural adhesive is cured in a forced manner.

18. The method as claimed in claim 17, wherein the structural adhesive is cured by irradiation.
