Guard rings for on-body analyte sensors

On-body analyte sensors may be designed for extended wear to provide ongoing measurement of physiological analyte levels. However, on-body analyte sensors may be susceptible to damage or dislodgment during wear due to routine interactions that occur with one's surroundings. Guard rings may be adapted to protect on-body analyte sensors from such interactions. Guard rings may comprise an annular body comprising an inner perimeter face, an outer perimeter face, a top edge, and a bottom face adapted for contacting a tissue surface. The inner perimeter face is shaped to circumferentially surround a sensor housing of an on-body analyte sensor. At least a portion of the outer perimeter face defines a chamfered surface extending between the top face and the bottom face. Adhesive pads or strips may further be engaged with the guard rings and aid in securing the guard rings to a surface, such as skin.
