Permanent magnet lancing device

A lancing device and a method for using the lancing device includes a plunger mechanism having a permanent magnet housed therein. The lancing device includes a movable element having at least one attracting object and at least one repelling object. The attracting object attracts the permanent magnet to move the plunger into a retracted position. The repelling object repels the permanent magnet to move the plunger into a lancing position to pierce the skin of a test subject. The use of the permanent magnet in the plunger mechanism reduces or eliminates multiple punctures due to plunger bounce or oscillation that can occur while a body fluid sample is being drawn.

Skin stimulus

Skin stimulus arrangements are described for creating a stimulus in the skin in the vicinity of a treatment or wound site to alleviate the perception of pain. First and second textured surfaces are provided for making contact with the skin, with the surfaces being moved to create a stimulus which alleviates the perception of pain. The movement may be linear, rotary or a combination of both, and just a single textured surface may be provided.

LATCH MECHANISM FOR PREVENTING LANCET OSCILLATION IN A LANCING DEVICE
20220265182 · 2022-08-25 · ·

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.

Method and apparatus for penetrating tissue

A body fluid sampling system for use on a tissue site includes a single drive force generator. A plurality of penetrating members are operatively coupled to the force generator. The force generator moves each of the members along a path out of a housing with a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. A flexible support member couples the penetrating members to define a linear array. The support member is movable and configured to move each of the penetrating members to a launch position associated with the force generator.

SYSTEMS AND TECHNIQUES FOR MONITORING SUBJECTS

The present invention generally relates to systems and methods for monitoring and/or providing feedback for drugs or other pharmaceuticals taken by a subject. In one aspect, the present invention is directed to devices and methods for determining a species within the skin of a subject; and producing feedback to a subject based on the determination of the species. The feedback may be, for example, visual, audible, tactile, a change in temperature, etc. In some cases, information regarding the determination of the species may be transmitted to another entity, e.g., a health care provider, a computer, a relative, etc., which may then provide feedback to the subject in some fashion. In some cases, the feedback may be directly indicative of the species, e.g., whether the species is present, the concentration of the species, whether a by-product of a reaction involving the species is present, whether a compound affected by the species is present, etc. However, the feedback may also be indirect in some embodiments. For example, the subject may be presented with an external reward, e.g., based on the determination of the species within the skin. For instance, a reward such as cash, coupons, songs, discounts, personal items, etc., may be offered based on the level of compliance of the subject. Still other aspects of the invention are generally directed to kits involving such devices (with or without the drug to be monitored), methods of promoting such systems, or the like.

METHODS AND DEVICES FOR CELL DETECTION

The present disclosure relates to a cartridge, detection module, system, and kit for cell and particle detection and analysis. Devices disclosed herein may include at least an optical source, a fluidic chip, and a detection module, wherein the sample flows within the fluidic chip past a detection window, where the cells or particles are imaged by an image acquisition and analysis module that may include an optical detector. The image acquisition and analysis module may count the cells or particles of interest in real-time, or near real-time, or the module may capture images of the cells in order to analyze the sample from combined images at a later time.

A container at least to some extent composed of a sheet of composite material, where the composite material includes an aluminum foil with a first and a second surface side, a first polymer layer, bonded to at least one of the two surface sides, where the aluminum foil covers, by way of the polymer layer, at least one aperture of a holder, where the composite material and the holder together form the container, where the holder accepts at least one analytical aid in a cutout, where the aluminum foil has been molded.

Vacuum assisted lancing system with elective vacuum release and method for blood extraction with minimal pain
09770201 · 2017-09-26 ·

A vacuum assisted lancing system for blood extraction can include a tubular body having a vacuum chamber, a lancing mechanism configured to removably couple with a lance, a vacuum mechanism including a piston slideably coupled within the body, a release mechanism for selectively holding the vacuum mechanism in an energized state, and an opening for allowing fluid communication between the vacuum chamber and an atmosphere surrounding the vacuum chamber. The system can include structure for selectively commencing dissipation of the vacuum and a fixed or adjustable depth controller. A method of manipulating a surface for blood extraction can include coupling the lancing system to the surface, blocking the opening, creating a vacuum, moving the lance coupler from a first position distal from the surface to a second position proximal to the surface, maintaining the vacuum for a period of time, and commencing dissipation of the vacuum by unblocking the opening.
