Analyte sensor antimicrobial configurations and adhesives

A continuous glucose monitoring system, comprising:

• an on-body analyte sensor comprising:
• a subcutaneous glucose sensor configured to be located under a skin surface of a user, the subcutaneous glucose sensor comprising a proximal portion and a distal portion, wherein the proximal portion is configured to be connected to an electrical connection and wherein the distal portion is in contact with an interstitial fluid for sensing signals representative of glucose levels;
• a sensor housing comprising the subcutaneous glucose sensor, wherein the sensor housing comprises a plurality of grooves on a bottom face of the sensor housing, and wherein the sensor housing is configured with an adhesive binder comprising a non-woven support material;
• and
• the electrical connection configured to be located above the skin surface and further configured to wirelessly transmit the signals representative of glucose levels via a Bluetooth protocol;
• an overbandage configured to circumferentially surround the sensor housing and adhere to the skin surface of the user,
• wherein the overbandage comprises a vapor-permeable backing, wherein the vapor-permeable backing comprises an aperture and a contact adhesive layer comprising an anchoring adhesive strip comprising a first strip portion and a second strip portion, a first adhesive layer laterally arranged to a first side of the anchoring adhesive strip, and a second adhesive layer laterally arranged to a second side of the anchoring adhesive strip,
• wherein the vapor-permeable backing comprises a first portion along the anchoring adhesive strip and a second portion for a remainder of the vapor-permeable backing, and wherein a thickness of the first portion is greater than a thickness of the second portion,
• wherein the non-woven support material has a first areal mass of less than 20 g/m2,
• wherein the overbandage has a moisture vapor transfer rate (MVTR) between 200 g/m2/day to 2,000 g/m2/day, and
• wherein the anchoring adhesive strip is in contact with the aperture such that the first strip portion and the second strip portion are disposed on opposing sides of the aperture, and wherein the overbandage further comprises first and second peelable release liners disposed upon first and second adhesive layers, respectively, and a third peelable release liner disposed upon the anchoring adhesive strip, wherein the overbandage is configured to be foldable along the anchoring adhesive strip when the third peelable release liner is removed, and wherein the overbandage, when folded along the anchoring adhesive strip, is configured to be seated against the sensor housing through a lateral engagement process with the anchoring adhesive strip, the first adhesive layer, and the second adhesive layer.
