Described here are meters and methods for sampling, transporting, and/or analyzing a fluid sample. The meters may include a meter housing and a cartridge. In some instances, the meter may include a tower which may engage one or more portions of a cartridge. The meter housing may include an imaging system, which may or may not be included in the tower. The cartridge may include one or more sampling arrangements, which may be configured to collect a fluid sample from a sampling site. A sampling arrangement may include a skin-penetration member, a hub, and a quantification member.

A reusable applicator for applying a microneedle patch to a skin of a subject which comprises a base for positioning onto the skin. The base comprises a skin-side end and a holder for holding the microneedle patch in position relative to the skin-side end. Two or more contact parts at the skin-side end can contact the skin. One or more are movable over the skin and away from the other contact 5 parts to stretch the skin at least during penetration of the skin by a microneedle of the patch. The applicator further comprises an interface for an actuator. The actuator actuates in operation a movement of the microneedle patch relative to the skin-side end to penetrate at least into the stratum corneum of the epidermis of the skin with the microneedle. A microneedle patch comprises a skin-adhesive surface for attaching the patch to the skin of a10 subject. The patch has one or more microneedles projecting from the skin-adhesive surface out of the patch. A stiffening body stiffens the patch in at least a parallel direction parallel to the skin-adhesive surface in a region of the skin-adhesive surface which includes the microneedle.

A blood draw device including an introducer and an actuator. The introducer has a proximal end portion, a distal end portion, and an inner volume, and includes a top surface having a first portion of a first length and a second portion of a second length. The first portion may have a smooth surface along the first length and the second portion has a plurality of ridges along the second length. The actuator includes an exterior portion positioned above the top surface and an interior portion positioned within the inner volume, wherein the exterior portion of the actuator includes an engagement member and a downwardly-extending tab projecting below the engagement member such that the downwardly-extending tab of the actuator may contact at least the plurality of ridges of the second portion of the introducer to provide at least one of tactile and audible feedback to a user.

An arrangement for producing a sample of body fluid from a wound opening created in a skin surface at a sampling site includes: a housing, the housing comprising a first opening; a skin interface member disposed in the first opening, the skin interface member comprising an inner member having a second opening, and an outer member at least partially surrounding the inner member and attached to the first opening; and at least one skin-penetration member configured and arranged to project within the second opening. Arrangements having alternatively constructed skin interface members are also described.

A lancet driver is provided wherein the driver exerts a driving force on a lancet during a lancing cycle and is used on a tissue site. The driver comprises of a drive force generator for advancing the lancet along a path into the tissue site, and a manual switch for a user interface input.

An apparatus includes a catheter, an introducer, and an actuator. A distal end portion of the introducer is configured to be coupled to a peripheral intravenous line. The introducer defines an inner volume having a first portion that defines an axis parallel to and offset from an axis defined by a second portion. A first portion of the actuator is movably disposed in the first portion of the inner volume. A second portion of the actuator is movably disposed in the second portion of the inner volume and coupled to the catheter movably disposed in the second portion of the inner volume. The actuator moves the catheter between a first position, in which the catheter is disposed within the introducer, and a second position, in which at least a portion of the catheter is disposed within the peripheral intravenous line.
