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 system includes an applicator and a dermal patch coupled to the applicator. The applicator includes a needle configured to puncture a subject's skin to draw a physiological sample, a first actuating lever configured to move form an undeployed position to a deployed position, and a second actuating lever configured to move form an undeployed position to a deployed position. The dermal patch includes a fluid reservoir configured to store a processing fluid, a sample collection chamber configured to receive the processing fluid and the physiological sample, wherein the applicator is configured to cause the needle to puncture the subject's skin to draw the physiological sample when the first actuating lever is moved from the undeployed lever position to the deployed lever position and cause the processing fluid to release from the fluid reservoir when the second actuating lever is moved from the undeployed position to the deployed position.

A system for collecting a physiological sample includes a dermal patch configured for attaching to a subject's skin and an applicator for coupling to the dermal patch. The dermal patch includes a reservoir configured to store a processing fluid, a sample collection chamber for receiving the processing fluid and a physiological sample extracted from a subject. The applicator includes at least one actuating lever for activating the dermal patch to receive the physiological sample from the subject and directing the physiological sample into the sample collection chamber.

Provided is a blood collection apparatus with which blood can be stably collected from a finger tip of any subject while ensuring safety and ease. This blood collection apparatus is provided with: a puncture site holding mechanism for holding a puncture site; a compression mechanism for performing an operation of compressing and releasing the puncture site when blood is collected from the puncture site; a container holding mechanism for holding a container for collecting blood flowing from a puncture wound at the puncture site; and a driving mechanism for varying the relative distance between the puncture site and the container by vertically moving the puncture site holding mechanism, the container holding mechanism, or the container held by the container holding mechanism when blood flowing from the puncture wound is collected.

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.
