Sensor inserter having introducer
First Claim
1. A sensor insertion assembly, comprising:
- an inserter housing;
an introducer, the introducer including;
a body portion having a proximal end and a distal end; and
a shaft portion comprising a distal end and a sidewall forming a channel with a first longitudinal opening, the shaft portion extending downwardly from an edge of the body portion, the shaft portion including a second longitudinal opening through the sidewall, the second longitudinal opening located adjacent the first longitudinal opening;
a sensor comprising a sensor body and a flange, the flange configured to pass through the second longitudinal opening of the sidewall in a first direction, and the flange extending from the sensor body in a second direction transverse to the first direction such that, when the flange is passed through the second longitudinal opening, the sensor is substantially releasably retained to the introducer;
an on-body electronics unit configured to couple with the sensor; and
a spring included in the inserter housing and operatively coupled to the introducer,wherein the spring is configured to move the introducer and retained sensor into a body of a subject; and
wherein the second longitudinal opening includes a first section that is wider than a width of the flange and a second section that is narrower than the width of the flange, wherein the sensor is releasable from the introducer when the flange is positioned along the first section and wherein the sensor is retained to the introducer when the flange is positioned along the second section.
