BODY FLUID LANCING, ACQUIRING, AND TESTING CARTRIDGE DESIGN

摘要

A lancet wheel (22) having a rim (23) with a plurality of lancets (24) extending radially inward from the rim is dropped in a circular frame (30) having a plurality of spokes forming a plurality of chambers (32) for facilitating drop -in assembly of the modular lancet wheel with the frame. A test ring (26) having a plurality of test sections (28) is assembled on the frame such that one test section is located adjacent each lancet to form an integrated cartridge (20). Each lancet includes a lancet tip (46) defining a capillary groove sized to collect a body fluid sample from the incision via capillary action. The lancet tip exits the chamber to form the incision in skin, the capillary groove collects the body fluid sample, the lancet tip retracts into the chamber, and a portion of the lancet contacts the test section to transfer the sample from the capillary groove to the test section to analyze the sample.
