Abstract
A body fluid sampling device is provided. A mesh may be used to guide blood or fluid to travel directly from the wound to an analyte detecting port on the cartridge. Thus the volume of blood or body fluid produced at the wound site irregardless of its droplet geometry can be reliable and substantially completely transported to the analyte detecting member for measurement.
Claims14
A body fluid sampling device comprising:
- a single cartridge;
- a plurality of penetrating members coupled to said single cartridge and operatively couplable to the penetrating member driver, said penetrating members movable to extend radially outward from the cartridge to penetrate tissue;
- a plurality of analyte detecting members coupled to said single cartridge, wherein at least one of said analyte detecting members positioned on the cartridge to receive body fluid from a wound in the tissue created by a penetrating member when the cartridge is in an operative position;
- and a mesh structure pushed and pierced by the penetrating member against the tissue in order to draw fluid generated by said tissue towards one of the analyte detecting members and
- wherein the mesh is a gradient mesh.
