Described here are devices, systems, and methods for analyte measurement. The analyte measurement devices and systems may be configured to produce a prompt that may convey information, instructions and/or encouragement to a user. In some variations, analyte measurement devices may be configured to change a prompt based on the replacement or addition of components of/to the device. In some instances, a prompt may be an auditory prompt and/or a visual prompt. In some variations, a system may comprise an analyte measurement device comprising a housing, a speaker, and a control unit. The housing may comprise a releasable housing portion comprising an identifier that is associated with a prompt. In some variations, a system may comprise an analyte measurement device and a skin that may releasably attach to the analyte measurement device and may comprise an identifier that is associated with a prompt.

A glucose meter includes a housing, and a first chamber and a second chamber defined in the housing. A first barrel is installed in the first chamber and adapted to accommodate multiple lancets therein. A second barrel is installed in the second chamber and adapted to accommodate multiple test strips therein. Additionally, each of the first and second chamber includes a hinged lid which is lifted to expose the first and second barrel from the top end of the first and second chamber. The hinged lids are actuated by buttons on the housing. The lancets are adapted to prick a user's finger in order to reveal blood. A user then positions the blood on the test strip to be absorbed and tested by the glucose meter.

The invention relates to analyte monitoring/drug (pharmaceutical agent) delivery device. The invention is suited for monitoring various blood constituents such as glucose. The device has a housing that at least partially encloses a plurality of microneedles disposed on a carrier and an electronics portion. Each microneedle is in fluid communication with a corresponding microchannel. Each microneedle is individually addressable. That is, each microneedle can be extended and retracted individually via an actuator. The electronics portion includes a processor and associated circuitry (e.g., memory, supporting electronics and the like), a motor or the like, a sensor, a power supply (e.g., battery) and optionally an interface. In general, the processor controls the operation of the device and is data communication with the actuator, motor, sensor and interface. The invention provides for autonomous operation, that is, without intervention of the user. The invention can optionally provide for calibration without intervention of the user. The invention can also provide for semi-continuous monitoring for day and night time. The invention can provide for up to four, or more, weeks of operation. The invention can provide for a device that is relative small in size, and therefore unobtrusive. The invention can also provide for device with remote control and interactive electronics. The invention may be also used for the delivery of various pharmaceutical agents including high potency drugs to minimize patient intervention and minimize discomfort.

Arrangements are provided including a base having a bore disposed therein extending from a first surface of the base through a second surface of the base, a fluid transport tube having a first end, a second end opposite the first end, and a lumen having an inner diameter, at least the second end of the tube being received within the bore of the base, and at least one fluid transport enhancing groove having at least a first section disposed in the second surface of the base and in fluid communication with the bore.

The present invention includes a system for withdrawing body fluids. The system includes a drive unit having a plunger which is moved from a resting position into a lancing position in order to carry out a lancing process and a lancing unit containing a lancet with a needle. The plunger and lancet are coupled together by a form fit in order to carry out a lancing process. The invention additionally concerns a method for temporarily extending a needle from a device for withdrawing body fluid as well as a lancing unit that can be attached to the drive unit.

A lancet magazine for use in a lancing aid is described comprising a plurality of lancets each having a lancet body at the proximal end of the lancet and a lancet tip at the distal end of the lancet, where the proximal end of the lancet points in the direction of the proximal end of the housing of the lancet magazine and the distal end of the lancet is aligned in the direction of the distal end of the housing and the lancets in the unused state are completely surrounded by the housing. Furthermore, an extension unit is movably connected to the housing in such a manner that the housing can be extended by movement of the extension unit in the direction of the distal end of the housing such that the lancet is prevented from emerging from the lancet magazine.

Devices systems and methods for fluid extraction and delivery to human or animal hosts are described. In embodiments, microneedles are employed to provide low infection risk and painless access to and administration of fluids. The disclosed embodiments address, among others, issues of cost, portability, ease of use in remote settings including use by untrained personnel, and others.

Arrangements are provided including a base having a bore disposed therein extending from a first surface of the base through a second surface of the base, a fluid transport tube having a first end, a second end opposite the first end, and a lumen having an inner diameter, at least the second end of the tube being received within the bore of the base, and at least one fluid transport enhancing groove having at least a first section disposed in the second surface of the base and in fluid communication with the bore.

Within examples, an apparatus for eliciting a blood sample includes a testing member rotatably mounted on a shaft; and an aperture for positioning a body part of the user relative to the edge of the testing member, wherein an edge of the testing member is shaped such as repeatedly to exert pressure on the skin of a user when the testing member is rotated.
