Body fluid sampling arrangements
First Claim
1. An arrangement for producing a sample of body fluid from a wound opening created in a skin surface at a sampling site, the arrangement comprising:
- a cartridge comprising a plurality of compartments and a plurality of sampling sites, wherein each of the sampling sites comprisesa 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, wherein the needle hub comprises a reagent pad and wherein the spring actuator is configured to drive the skin-penetration member to form the wound opening; and
a detector assembly,wherein each of the compartments at least partially encloses the skin-penetration member, spring actuator, and needle hub of a respective sampling site of the plurality of sampling sites.
