Abstract

A glucose monitor having only a test strip reader and wireless transmission to a remote hand held calculation processor. All glucose data processing occurs in a remote hand held calculator processor with the glucose monitor providing only sensing and wireless transfer of data. In an embodiment, the glucose monitor includes a button for use in wirelessly pairing the monitor to a smart phone for data communication with a non-proprietary communication protocol, and a light source to communicate the progress of the pairing. In a further embodiment, the glucose monitor includes a switch coupled to the strip reader such that power is applied to the monitor when a test strip is inserted and power is removed with the withdrawal of the test strip. In another embodiment, inserting the test strip and activating the switch also places the glucose monitor into the pairing search mode to communication with a host remote processor.
