An apparatus for insertion of a medical device in the skin of a subject is provided, as well as methods of inserting medical devices. Embodiments include removing a substantially cylindrical cap from an inserter to expose a substantially cylindrical sleeve, removing a cover from a substantially cylindrical container holding sensor components, and fitting the sensor components into the inserter.

A lancing device including a latch that pivots between a non-blocking position allowing a lancet carrier and a lancet to advance and retract through a first forward and reverse lancing stroke and a blocking position preventing further/excess/secondary oscillation of the lancet carrier and lancet. The pivotal latch can pivot about an axis perpendicular (e.g., for an L-shaped latch) or parallel/coaxial (e.g., for a sleeve latch) to the advancement and retraction motion of the lancet carrier and lancet.

Devices are provided to automatically inject drugs or other payloads into or beneath skin. These devices include an injector configured to drive a hollow needle into the skin and subsequently to deliver the payload through the hollow needle. Applied suction acts to draw blood from the puncture formed in the skin through the hollow needle, into the device, and to a sensor, blood storage element, or other payload. In some examples, the blood is drawn through the hollow needle when the hollow needle is penetrating the skin. In some examples, these devices are additionally configured to retract the hollow needle from the skin and/or to perform some other functions. These devices can be wearable and configured to automatically access blood or deliver a payload into skin, for example, to operate at one or more points in time while a wearer of a device is sleeping.
