A method of assembling a lancet housing assembly comprising multiple lancets for use in a portable handheld medical diagnostic device for sampling bodily fluids from a skin site of a patient is disclosed. The method includes forming a plurality of lancet structures in a lancet sheet. The lancet sheet has a removable ledge for releasing the lancet structures. The removable ledge of the lancet sheet is flexed for releasing the lancet structures from the removable ledge.

A method for performing an assay to determine the presence or concentration of an analyte contained in a sample of body fluid by using a device comprising at least one analyte quantification member and a sensor associated therewith, the method includes: applying a first sample to the analyte quantification member; and detecting the presence or absence of an adequate sample volume; wherein upon detection of the absence of an adequate sample volume, initiating a finite timed period, and signaling the user to introduce a second sample of body fluid to the analyte quantification member. Associated arrangements and devices are also disclosed.

A lancet device generally includes a housing having opposing lateral sides extending between a forward end and a rearward end, and a shield coaxially and movably associated with the housing. The housing includes a plurality of longitudinal ribs extending along a portion of at least one of the opposing lateral sides. The plurality of longitudinal ribs form a finger grip on at least one of, and typically both of the opposing lateral sides. The shield is generally movable from a first position in which the shield extends outwardly from the forward end of the housing to a second position in which the shield is at least partially moved within the housing, based on axial pressure applied by the user against the finger grip formed by the longitudinal ribs.

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.

A kind of safety lancing device has a front cap and lancet holder with feature: the front cap and lancet holder are connected in insert-plug type, and the front cap is equipped with connecting block at connection end and the lancet holder is equipped with slot at connection end. And the slot includes slideable slot and deadlock slot. The slideable slot is located in front of deadlock slot. The latch is set at the flexible arm end of ejection pin and the latch is equipped with bayonet at the front end and equipped with latch hook at rear end; the width of slideable slot and deadlock slot is larger than that of latch; the slideable slot is equipped with a blocking shoulder at rear end and the deadlock slot is equipped with latching shoulder at front end.

Some embodiments are directed to a portable electronic device for analyzing an analyte. The portable electronic device includes a housing, an adapter detachably coupled to the housing and a processor disposed in the housing. The adapter includes a body defining an opening for receiving a test strip and an interface port disposed within the body. The interface port is configured to read a signal from the test strip. The processor is communicably coupled to the interface port. The processor is configured to determine at least one parameter of the analyte based on the signal received from the interface port.

An arrangement for producing a sample of body fluid from an opening created in a skin surface at a sampling site including a cartridge with a plurality of compartments and a plurality of sampling sites, and a detector assembly. Each sampling site includes a skin-penetration member having a first end configured to pierce the surface of the skin and an inner lumen in communication with the first end, a spring actuator operatively associated with the skin-penetration member, and a needle hub connecting the skin-penetration member and the spring actuator. The needle hub includes a reagent pad and the spring actuator is configured to drive the skin-penetration member to form the wound opening. Each compartment at least partially encloses the skin-penetration member, the spring actuator, and the needle hub of a respective sampling site.
