Method of manufacturing a fluid sampling device with improved analyte detecting member configuration
View Patent ↗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.
1. A method of manufacturing an actuation device, said method comprising:
providing a cartridge containing a plurality of penetrating members;
sterilizing the cartridge and the penetrating members before assembling the analytical analyte detecting members on the cartridge,
sealing the cartridge to form a sealed cartridge;
mounting the analyte detecting members on an exterior surface of a sealed cartridge containing the plurality of penetrating members in a sterile condition; and
adding a second protective layer to protect the analyte detecting members mounted on an outer surface of the sealed cartridge.
2. The method of claim 1 wherein the cartridge comprises a radial disc with a plurality of cavities, each of said cavities holding one of said penetrating members.
3. The method of claim 1 wherein the cartridge is sealed with a metallic foil.
4. The method of claim 1 wherein analyte detecting members are coupled to at least one reference electrode and at least one working electrode.
5. The method of claim 1 further comprising attaching a wicking member to each of the analyte detecting members to bring body fluid from a wound created on a patient to the analyte detecting member.
6. The method of claim 1 further comprising attaching a wicking member to each of the analyte detecting members to bring body fluid from a wound created on a patient to the analyte detecting member, said wicking member placed on an exterior surface of a sealed cartridge and positioned on the side of the cartridge with sealed cavity openings.
7. The method of claim 1 wherein a second foil layer covers the analyte detecting member and the second protective layer.
