Abstract:
A lancing device has a carousel of lancets removably received in a housing. In exemplary embodiments, the lancing device includes a sterility cap positioning mechanism that removes sterility caps from the lancets for actuation and afterwards replaces the sterility caps onto the lancets. Preferably, the lancing device includes a lancet advancing mechanism that automatically advances sequential lancets of the lancet carousel for charging and actuating, and a drive mechanism for actuating the lancets. Also provided are replacement lancet carousels, which include a cylindrical carrier with axial openings and a plurality of the lancets axially oriented in the openings.
Abstract:
This invention includes a latch member for a latch assembly, suitable for a removable battery package. The latch member accommodates attachment to a latch coupler of an electronic device. A resilient, springy-metal, deflectable latch member is provided. The latch member includes arms for coupling with a latch coupler, a locking arm for adhering to a plastic housing, and spring arms that cause a torsion element to twist when force is applied to the arms. The torsion element is at least twice as long as it is wide, and provides reliable return force despite a short travel length of the arms. The latch member is suitable for battery packages in which space is a premium.

Abstract:
Lancing devices and methods of use are provided. Also provided are lancets for use with lancing devices. Certain embodiments of the lancing devices include a front end cap with an annular skin-engaging surface surrounding a piercing aperture.
Abstract:
A low-pain lancing device includes a drive mechanism for loosely engaging a lancet and driving the lancet along an axial path. The drive mechanism has a first coupling element and the lancet has a second coupling element, which together form a loose coupling therebetween, wherein interaction between the first and second coupling elements permits a degree of freedom of movement between the lancet and the drive mechanism in a lateral direction, perpendicular to the axial path of travel of the lancet, to prevent non-axial movement of the lancet tip during lancing and thereby reduce pain experienced by the subject.
Abstract:
A lancet, a housing for the lancent, and a combination depth and activation control assembly. The lancet includes a needle, a needle-holding section, and an operating section with an opening. A drive spring is mounted within the opening and between the lancet body and the housing. The control assembly includes a control member with a control interface knob and a control shaft. The control shaft has multiple stop surfaces that are alignable with an engagement surface on the lancet body to control the lancing depth. And the control shaft has a release surface that engages the release member to disengage the engagement member to activate the lancing stroke. Additional features includes a safety interlock for preventing accidental activiation of the lancing device, ridges on the housing for providing discrete locked and depth setting positions, and a keyed sterility cap for preventing accidental removal of the cap.
Abstract:
A lancing device and replaceable multi-lancet cartridge for use in sampling of body fluids. Sequential lancets of the cartridge are translationally retracted along a storage path, pivoted into an angularly offset firing path, and translationally propelled by a drive mechanism to lance the subject's skin.
Abstract:
Lancets and methods of use are provided. Embodiments include lancets including a sleeve mounted to an elongated body having a needle terminating in a sharp tip.
