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.

Lancet

The invention relates to a lancet for performing an incision. The lancet has a blade for providing an incision and a trigger housed in a housing. The trigger has a first trigger arm, a second trigger arm and a flexible member connected to the second trigger arm. A resilient member may be disposed within the housing in a pre-cutting state in which it stores energy and arranged to exert a force for moving the second trigger arm and the blade from a first stowed position through a cutting position and to a second stowed position.

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.

Handheld medical diagnostic devices with lancing speed control

A method of controlling lancing speed of a lancing structure of a portable handheld medical diagnostic device includes providing an elongated lancet structure having a skin piercing end and a blood transport portion adjacent the skin piercing end. The skin piercing end when displaced makes an incision at a skin site to produce an amount of bodily fluid from the skin site and in which the blood transport portion transports the amount of bodily fluid away from the skin site for use by a measurement system in making a physiological measurement. A spring-driven motor assembly is operatively connected to the lancet structure. The spring-driven motor assembly displaces the lancet structure toward the skin site to make the incision for producing the amount of bodily fluid and retracts the lancet structure to carry the amount of bodily fluid away from the skin cite. A speed control mechanism is engaged with the spring-driven motor assembly as the spring-driven motor assembly retracts the lancet structure thereby decelerating the lancet structure as the lancet structure is retracted away from the skin site.

Medical device inserters and processes of inserting and using medical devices

An apparatus for insertion of a medical device in the skin of a subject is provided, as well as methods of inserting medical devices. Embodiments include removing a substantially cylindrical cap from an inserter to expose a substantially cylindrical sleeve, removing a cover from a substantially cylindrical container holding sensor components, and fitting the sensor components into the inserter.

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.

Lancing device for obtaining samples of body fluid
