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 device for obtaining a biological sample, such as a capillary blood collection device, that has the ability to lance and squeeze the finger, collect the sample, stabilize the sample, and subsequently dispense the sample in a controlled manner is disclosed. The device also simplifies and streamlines the capillary blood collection by eliminating workflow variabilities which are typically associated with low sample quality including hemolysis and micro-clots.

A needle including a cannula having a multi-beveled point is disclosed. The multi-beveled point includes a primary bevel, two middle bevels, and two tip bevels. Each of the middle bevels extends between the primary bevel and one of the tip bevels. The primary bevel is provided on the cannula at a first angle of inclination and a first angle of rotation, the two middle bevels are provided on the cannula at a second angle of inclination and a second angle of rotation, and the two tip bevels are provided on the cannula at a third angle of inclination and a third angle of rotation. The third angle of inclination is greater than the second angle of inclination, the second angle of inclination is greater than the first angle of inclination, and the second angle of rotation is equal to the third angle of rotation.

A collection device which directs a flow of blood into a container and provides a controlled blood flow path that ensures blood flow from a collection site to a collection container is disclosed.

A pressing type disposable safety lancet with spring pilot structure consists of a shell, a lancet core, a spring and a trigger. The spring with a pilot structure at the outside makes the elastic force of the spring act along the ejection direction of the lancet core; the locking mechanism is formed by the cooperation of the elastic clamp at the tail of the trigger and the lancet core; the unlocking mechanism is formed by the front of pilot structure and the end of the elastic clamp through the unlocking bevel; when it's pressed during the use, the trigger moves backwards in the shell, the front of the pilot structure forces the end of the elastic clamp to open under the action of the unlocking bevel, and the lancet core is fired for puncturing under the action of the spring after the hook unhooks from the locking critical point.

An electrical venous stimulation apparatus comprising a powered signal generator, the signal generator configured to generate a specified electrical output signal. The apparatus also includes a plurality of electrodes in electrical communication with the signal generator and configured, to be placed in electrical communication with a subject, The electrical output signal sent to the subject, includes an output voltage, electrical current, and waveform that changes with time in a preprogrammed repeating cycle. The output voltage, electrical current, and waveform are configured to elicit a physiological response that stimulates a plurality of peripheral nerves in the subject, activates a venous muscle pump mechanism in one or more limbs of the subject, and non-invasively alter the physiology of target vein(s), wherein the target vein(s) is caused to distend under the surface of the subject's skirt.

Microelectromechanical system are disclosed that include at least one electrode, microelectrode or combination thereof, wherein the at least one electrode comprises a carbon material, a glassy carbon material or a combination thereof. Contemplated systems are suitable for μ-ECoG arrays. Additional microelectromechanical systems are disclosed that include at least one electrode, microelectrode or combination thereof, wherein the at least one electrode comprises a carbon material, a glassy carbon material or a combination thereof; at least one substrate, surface, layer or a combination thereof, wherein the at least one electrode, microelectrode or combination thereof is disposed on, coupled with or otherwise layered on the at least one substrate, surface, layer or a combination thereof; and at least one bump pad, wherein the at least one electrode, microelectrode or combination thereof is coupled with the at least one bump pad via at least one conductive metal. A method of making a microelectromechanical system includes patterning a polymer precursor, a carbon-containing material or a combination thereof onto a surface, a substrate, at least one layer or a combination thereof; and heating or pyrolysing the polymer precursor, a carbon-containing material or a combination thereof in order to form a glassy carbon material. Uses of microelectromechanical systems are also contemplated to measure at least one electrical property in a mammal or for electrocorticography.

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.
