1. A medical device, comprising:
a sensor to observe a characteristic of an anatomy;
a sensor base coupled to the sensor such that the sensor extends outwardly from the sensor base; and
a coupling system to couple the sensor base to the anatomy, the coupling system includes a first adhesive member and a second adhesive member that each define a bore to enable the sensor to pass through the first adhesive member and the second adhesive member, where the first adhesive member couples to the sensor base and the second adhesive member is configured to couple to the anatomy;
where the first adhesive member includes:
a central hub portion that defines the bore for the first adhesive member, and
a plurality of sections that are spaced apart about a perimeter of the first adhesive member to form the perimeter of the first adhesive member,
where the plurality of sections are symmetric to a central axis of the bore of the first adhesive member,
where the first adhesive member further includes a plurality of cut-outs to direct moisture to an ambient environment surrounding the medical device,
where the plurality of cut-outs define a main channel that surrounds the central hub portion and a plurality of intermediate channels between adjacent ones of the plurality of sections,
where the plurality of intermediate channels are proximate a perimeter of the sensor base and the plurality of sections are within the perimeter of the sensor base; and
where the second adhesive member includes:
a backing layer,
a skin adhesive layer, and
a second plurality of cut-outs that are in communication with the main channel,
where the backing layer couples to the first adhesive member and the skin adhesive layer is configured to couple to the anatomy;
where the second plurality of cut-outs extend through both the backing layer and the skin adhesive layer to extend beyond the perimeter of the sensor base, each of the second plurality of cut-outs includes a first portion and a second portion,
where each first portion extends along a first axis and is in alignment with and in communication with a section of the main channel,
where each second portion extends along and is in communication with a respective one of the plurality of intermediate channels,
where each second portion extends along a second axis that is substantially perpendicular to the first axis, and
where each second portion of the second plurality of cut-outs extends beyond an end of the respective one of the plurality of intermediate channels to direct the moisture from the anatomy to the respective one of the plurality of intermediate channels and to the ambient environment.
