Abstract
The present technology relates to a pad for forming a seal forming structure against a user's skin for use with a patient interface, the pad comprising, a base layer, a fibre layer comprising a plurality of fibers for contacting a patient's skin, and a connection layer for connecting the fibers to the base material, wherein the base layer and/or the fibre layer is/are adapted to act as a reservoir for substances. Furthermore, it relates to a set of pads, a kit and a patient interface.
Claims25
A pad for forming a seal forming structure against a user's skin for use with a patient interface, the pad comprising:
- a base layer having a first permeability to at least one substance;
- a fiber layer comprising a plurality of fibers for contacting a patient's skin, each fiber of the fiber layer being spaced apart from the base layer;
- and
- a connection layer for connecting the fibers to the base layer, the connection layer having a second permeability to the at least one substance;
- wherein the base layer and/or the fiber layer is/are adapted to act as a reservoir for the at least one substance;
- wherein the first permeability is an adjusted permeability that is configured to allow controlled speed of substance migration from the base layer to the connection layer;
- wherein the second permeability is an adjusted permeability that is configured to allow controlled speed of substance migration from the connection layer to the fiber layer;
- and wherein the first permeability is greater than the second permeability.
