1. An introducer configured to insert a sensor into a patient, the introducer comprising:
a housing detachably connectable to a sensor hub containing a sensor, wherein the sensor hub contains the sensor prior to connection to the housing, the housing including a needle cover, wherein the needle cover is an internal compartment of the housing; a needle that is moveable with respect to the needle cover and is extendable out of, and retractable into, the housing; a needle holder connected to the needle and contained within the housing; and a spring having a top end in contact with the needle holder and a bottom end in contact with the housing, wherein said needle holder and spring are configured such that, when the housing is connected to the sensor hub, said spring is in a compressed position and the needle extends out of the housing to insert the sensor into the patient, and such that disconnection of the housing from the sensor hub causes said spring to expand, thereby retracting the needle into the housing to be covered by said needle cover inside the housing, and the sensor remaining inserted in the patient; wherein the housing includes a mating component to mate with the sensor hub and hold said spring in said compressed position when the housing is connected to the sensor hub; and wherein the mating component includes a lock that locks the needle holder into the needle extended position when the housing is connected to the sensor hub. |
