Abstract
An assembly is described that combines blood chemical analysis with lancing in a single multiple-test disposable cartridge. The penetrating members can be assembled and sterilized without damaging the analytical chemistry, and the functioning of the present radical disc cartridge mechanism is not substantially modified.
Claims12
A device for use in a body fluid sampling system for measuring analyte levels in the body fluid, said device comprising:
- a cartridge;
- a plurality of penetrating member in said cartridge;
- and
- a plurality of analyte detecting members mounted on the cartridge, said detecting members mounted on an upper, outer surface of said cartridge and positioned to receive fluid flowing from a wound created by said penetrating member in the tissue, each of said detecting members comprises a plurality reference electrodes, counter electrodes, working electrodes, wherein all of said reference electrodes are electrically coupled together, and only one set of counter and working electrodes can be active at any one time.
1 more element
An actuation device comprising:
- a combined lancing and blood sample analysis device in a single disposable cartridge;
- said cartridge manufacture by allowing penetrating members to be pre-sterilized before assembling the analytical analyte detecting members on the cartridge, wherein the analyte detecting members are mounted on an exterior surface of a sealed cartridge containing a plurality of penetrating members in a sterile condition, each of said detecting members comprises a plurality reference electrodes, counter electrodes, working electrodes, wherein all of said reference electrodes are electrically coupled together, and only one set of counter and working electrodes can be active at any one time.
