Abstract

The present invention provides an applicator for inserting at least a portion of an in vivo analyte sensor for sensing analyte levels in a subject's bodily fluids, thereby reducing tissue damage at the sensor insertion site and increasing the likelihood of successful sensor insertion. [Solution] The applicator includes a drive spring, a pull-out spring, a sensor electronic component carrier, a sharp component carrier with a sharp portion, and an analyte sensor. The drive spring, by applying a first force to the applicator, displaces the sensor electronic component carrier and the sharp component carrier from a first position within the applicator, spaced apart from the skin surface, to a second position adjacent to the skin surface. At the second position, the sharp portion and a portion of the analyte sensor are positioned below the skin surface, in contact with the subject's bodily fluids. The pull-out spring displaces the sharp component carrier from the second position to a third position within the applicator, and by applying a second force to the applicator, the sharp portion is pulled away from the skin surface.

Claims

[Claim 1] An applicator for inserting an analyte sensor into a subject, Drive spring, Pulling spring, Sensor electronic component carrier, A sharp parts carrier equipped with sharp edges. Launch pin, Sheath, and Includes an analyte sensor, The launch pin is configured such that, upon application of a first force, one or more sheath stubs of the sheath are disengaged from one or more sensor electronic component carrier latches of the sensor electronic component carrier, thereby extending the drive spring. The drive spring is configured to displace the sensor electronic component carrier and the sharp component carrier from a first position within the applicator, which is spaced apart from the skin surface, to a second position adjacent to the skin surface, where the sharp portion and a portion of the analyte sensor are positioned below the skin surface at the second position, in contact with the subject's bodily fluids, and An applicator configured such that the extraction spring displaces the sharp part carrier from the second position to the third position within the applicator, thereby extracting the sharp portion from the skin surface.
