Abstract: A device for sampling and/or analyzing blood or other body fluid of a subject. A housing contains a plurality of lancets and optionally includes test elements to take up a sample of blood, an evaluation system and a display. A complete system that can be handled as a single device, for example in the form of a wristwatch, includes a multiplicity of test elements and lancets, which can be brought successively to a working position to perform multiple measurements. A cassette or carrier includes multiple lancets and/or test elements, for insertion into the device.

Abstract: A disposal device for a medical test item such as a blood glucose test strip or a lancet, the device including an outer shell bounding an interior chamber, an opening through the shell in communication with the chamber, and a clip for securing the device to an external structure. Curved or angled panels, or flexible sections of the shell can be provided at or adjacent the opening to resist removal or discharge of contents.

Abstract: A lancet having a coupling profile that is compatible with lancet holding features of standard lancing devices, but is keyed for mounting in a non-standard lancing device having a cooperating keyed coupling profile; a lancing device having a keyed lancet coupling for receiving a correspondingly keyed lancet but preventing use of unauthorized lancets; and a method of preventing use of unauthorized lancets with a lancing device.
