Tracheostoma plaster
View Patent ↗To solve the problem of providing a tracheostoma plaster that has a good sealing effect in the area of skin directly bordering a tracheostoma, a tracheostoma plaster ( 10 ) is proposed, having a proximal and a distal side ( 12, 14 ), having an adhesive strip ( 16 ) arranged on the distal side, having a receptacle ( 36 ) for a tracheostoma aid and having an annular bead ( 20 ), which is arranged on the proximal side of the plaster on a portion of the same, wherein the receptacle is surrounded by the annular bead.
1. A tracheostoma plaster comprising:
a body having a proximal side and a distal side, an adhesive strip arranged on the distal side of the body, said body having a receptacle for a tracheostoma aid, the receptacle having a mounting adapter for the tracheostama aid and a distal end with a chamfered edge for guiding the tracheostoma aid into the receptacle, said body having an annular bead arranged on a portion of the proximal side, the annular bead having an inner wall and a proximal surface, wherein the receptacle is fully surrounded by the inner wall of the annular bead.
2. A tracheostoma plaster according to claim 1 , wherein the bead further comprises a proximal surface having an inflection point when viewed from a cross-section that runs parallel to a centerline of the plaster.
3. A tracheostoma plaster according to claim 1 , wherein the bead has an outer marginal area running approximately parallel to the adhesive strip.
4. A tracheostoma plaster according to claim 1 , wherein the bead consists of a soft, pressure-sensitive material.
5. A tracheostoma plaster according to claim 1 , wherein the distal side of the bead has a basically planar design.
6. A tracheostoma plaster according to claim 1 , wherein an inner marginal area of the bead attached to the receptacle is generally parallel to the adhesive strip.
7. A tracheostoma plaster according to claim 1 , wherein the receptacle has a proximal edge, which is connected with the bead.
8. A tracheostoma plaster according to claim 7 , wherein the proximal edge merges without any projection into the bead.
9. A tracheostoma plaster according to claim 1 , wherein the receptacle consists of a flexible material.
10. A tracheostoma plaster according to claim 1 , wherein a distal end of the mounting adapter forms a flush seal with a distal surface of the bead.
11. A tracheostoma plaster according to claim 1 , wherein the mounting adapter has a proximal end merging with the bead.
12. A tracheostoma plaster according to claim 1 , wherein at least portions of the proximal surface of the plaster, which are not connected with the bead, are adhesive.
