Physiological characteristic sensor system

A physiological characteristic sensor system, comprising:

• a physiological characteristic sensor that includes a housing having a first housing portion coupled to a second housing portion and a sensor, the second housing portion having a bottom region and a sidewall extending upwardly from the bottom region, wherein the first housing portion and the second housing portion cooperate to enclose a portion of the sensor, and the portion of the sensor is coupled to a first surface of the second housing portion;
• and
• a sensor inserter configured to be coupled to the physiological characteristic sensor, the sensor inserter including a frame, a sensor carrier and a sensor retainer, the sensor carrier including a retaining flange, the sensor retainer coupled to the sensor carrier so as to be received within the retaining flange, and the sensor carrier coupled to the frame, the frame having a plurality of ribs spaced apart about an inner perimeter of the frame, the sensor retainer including a central bore configured to receive the housing of the physiological characteristic sensor and a plurality of retainer arms spaced apart about a perimeter of the central bore to surround the housing of the physiological characteristic sensor, the plurality of retainer arms configured to couple to the sidewall extending upwardly from the bottom region of the second housing portion in a second state while the second housing portion is at least partially inside the sensor inserter and configured to be uncoupled from the second housing portion in a first state while the second housing portion is at least partially inside the sensor inserter, each retainer arm of the plurality of retainer arms is movable between the first state and the second state, in the first state, a terminal end of each retainer arm of the plurality of retainer arms is spaced apart from a surface of the sensor retainer to define a gap, in the second state, the terminal end of each retainer arm of the plurality of retainer arms contacts the surface of the sensor retainer, and each rib of the plurality of ribs biases a respective retainer arm of the plurality of retainer arms to eliminate the gap in the second state.
