The lancet device includes a housing and a lancet having a puncturing element. The lancet is disposed within the housing and is adapted for axial movement between an initial or pre-actuated position wherein the puncturing element is retained within the housing, and a puncturing position wherein the puncturing element extends through a forward opening in the housing. The lancet device includes a drive spring disposed within the housing for biasing the lancet toward the puncturing position, and a retraction or return spring for returning the lancet to a position within the housing where the puncturing element is disposed within the housing. The retraction spring thereafter maintains engagement with the lancet to assist in preventing the puncturing element from again projecting outward from the forward opening in the housing.

Apparatuses and methods for dried blood spot (DBS) sample collection are disclosed. A dried blood spot sampling device is configured to deliver blood through a passage to an absorbent disk in the device and control an amount of blood saturating the absorbent disk. The sampling device may include a manually actuatable component adjustable between a first position, in which an outlet of the passage is not in physical contact with the absorbent disk, and a second position, in which the outlet of the passage is in physical contact with the absorbent disk.

An activation/retraction mechanism for a lancing device comprising a pusher (10; 20; 30; 40; 50) comprising a first biasing member arranged to displace the pusher in a distal direction; and a lancet holder comprising a lancet for penetrating the skin of a subject, and a second biasing member arranged to displace the lancet holder in a proximal direction; wherein the lancet holder and the pusher are arranged in a housing of the lancing device in such a way that a distal end of the pusher engages a proximal end of the lancet holder to push the lancet holder in a distal direction when the first biasing member displaces the pusher distally. The distal end of the pusher and the proximal end of the lancet holder are arranged to disengage from each other when the pusher has been displaced dis-tally a predetermined length from its initial position, whereby the lancet holder may re-turn to its initial position under influence of the second biasing member.

The invention is related to a hand-operated actuator mechanism for driving a piercing element with increased safety. The actuator mechanism comprises a mounting element connected to a trigger element by a first breakable connection element. It also comprises a piercing element carrier connected to the trigger element by a second breakable connection element. The trigger element further comprises a pushing member that can be pushed with a human finger. The first breakable connection element is configured to be broken by means of a predetermined pushing finger force pushing said pushing member. The piercing element carrier being movable between an initial position wherein the first and the second breakable connection elements are unbroken, and a stop position wherein an abutment stops a movement of the piercing element carrier.

The disclosed apparatus, systems and methods relate to devices, systems and methods for the collection of bodily fluids involving a single-use actuation and retraction mechanism disposed within a collector.

A blood sequestration device configured to isolate an initial, potentially contaminated portion of blood from the flow of blood of a patient, prior to directing the flow of blood to an outlet port where the blood can be accessed. The blood sequestration device including a body member having an interior wall defining a fluid conduit having a distal portion, a first proximal portion, and a second proximal portion, wherein the first proximal portion defines a sequestration chamber configured to isolate an initial portion of blood of a flow of blood, a vent path configured to enable the escape of gas initially trapped within the sequestration chamber.

A blood collection tube holder having a retractable single needle and a body comprising substantially parallel and laterally spaced apart barrel and needle retraction cavities separated by a partial wall that facilitates lateral movement of the single needle from the barrel cavity into alignment with the needle retraction cavity to initiate needle retraction. The barrel and a frontal attachment to the barrel are cooperatively configured to facilitate relative sliding movement between in a direction that is transverse to the longitudinal axis through the retractable single needle to initiate needle retraction.
