Body fluid sampling arrangements

摘要

An arrangement for producing a sample of body fluid from an opening created in a skin surface at a sampling site including a cartridge with a plurality of compartments and a plurality of sampling sites, and a detector assembly. Each sampling site includes a skin-penetration member having a first end configured to pierce the surface of the skin and an inner lumen in communication with the first end, a spring actuator operatively associated with the skin-penetration member, and a needle hub connecting the skin-penetration member and the spring actuator. The needle hub includes a reagent pad and the spring actuator is configured to drive the skin-penetration member to form the wound opening. Each compartment at least partially encloses the skin-penetration member, the spring actuator, and the needle hub of a respective sampling site.
