A lancing device with rear adjustment of penetration depth includes a cap, cap holder, ejection pin and shell, wherein: the lancing device has an external and medium depth adjusting sleeve. The ejection pin is located in the medium sleeve and the external depth adjusting sleeve is sleeved outside the medium sleeve; the external sleeve connects axially and circumferentially to the shell, and a rotary locating mechanism is between the external sleeve and the shell; the medium sleeve is connected circumferentially and axially in a sliding way, and a rotary moving mechanism is between the medium the external sleeve, and the medium includes a passive impact face relative to the active impact face of the ejection pin; the external sleeve includes a manual adjusting ring outside the lancing device at the middle and rear part, and rotates to drive the medium sleeve to move axially, changing the needle tip penetration depth.

Devices and methods for withdrawing bodily fluid from a subject are disclosed herein. In some embodiments, a handheld device can include a housing having an opening, a skin-piercing assembly, and an actuator coupled to the skin-piercing assembly. The skin-piercing assembly can include a casing, a drive member pivotably mounted within the casing and carrying a blade, and a biasing member coupling the drive member to the casing. The actuator can be movable relative to the housing from a first position to a second position. In the first position, the drive member can engage the casing to maintain the biasing member in a biased configuration. Movement of the actuator from the first position to the second position can disengage the drive member from the casing to permit the biasing member to drive the blade at least partially through and/or across the opening in the base.

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.

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 pen format liquid collection device includes an elongate generally tubular housing (12, 112, 212, 312) able to be held by hand and having an opening at one end, and at least one liquid take-up element (30, 130, 230, 330) mounted in the housing so as to be positioned or positionable to project at the opening, the at least one liquid take-up element then further postionable by hand manipulation of the housing to contact a volume of liquid to thereby take-up a sample of the liquid to be analysed. At least one retention element (230a, 330a) is supported in the housing. The at least one liquid take-up element and the at least one retention element are arranged whereby they are relatively movable into contact, and the at least one retention element is adapted on contact to in turn take-up the sample and retain the sample or a component thereof for in situ analysis or later recovery while protected within the housing. The liquid take-up element is preferably a capillary.

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.
