TEST STRIP WITH SLOT VENT OPENING

摘要

The test strip (10) includes a base substrate (12), a spacing layer (14) and a covering layer (16) comprising body cover (18) and chamber cover (20). The spacing layer (14) includes a void portion (22) to provide a sample-receiving chamber (24) extending between the base substrate (12) and the covering layer (16). The base substrate (12) carries an electrode system (26) including a plurality of electrodes (28) and electrode traces (30) terminating in contact pads (32). The electrodes are defined as those portions of electrodes traces (30) that are positioned within the sample-receiving chamber (24). A suitable reagent system (33) overlies the electrodes within the sample-receiving chamber. The body cover (18) and the chamber cover (20) overlying the spacing layer (14) define a slot (34) therebetween, the slot defining a vent opening communicating with the sample-receiving chamber to allow air to escape the chamber as a sample fluid enters the chamber from the edge opening or fluid receiving opening (35). The test strip therefore includes a dosing end (36) and a meter insertion end (38).
