The carrier 204 drives the sensor 42 and, optionally, the intro ducer 120 into the skin of the patient using, for example, a cocked or wound Spring, a burst of compressed gas, an electromagnet repelled by a Second magnet, or the like, within the insertion gun 200.
In one embodiment, two or more components of the housing 45, for example, the base 74 and the cover 76, fit together tightly to form a hermetic, waterproof, or water resistant Seal So that fluids can not flow into the interior of the on-skin sensor control unit 44.
This may be useful to avoid corrosion currents and/or degradation of items within the on-skin Sensor control unit 44, Such as the conductive contacts, the battery, or the electronic components, particularly when the patient engages in Such activities as showering, bathing, or Swimming.
When in the normal outward position, shoulders 402 on the outer Sur faces of tabs 322 engage the rim 404 of opening 376 to prevent the actuator button 324 from being depressed, thereby avoiding accidental firing of inserter 310.
