Patent ID: 8401873

Claim:
A device for managing health data, comprising: a housing portion including a health data management system and a data communications element that provides data communications between the health data management system and an external processing device, the health data management system including a meter for measuring a reaction between a reagent and an analyte in a user sample to determine an analyte concentration in the user sample; and a cap that is removably coupled to the housing portion, the cap including a temperature sensor that provides a measurement of ambient temperature to the health data measurement system, and wherein a level of the reaction between the reagent and the analyte is affected by a temperature of the reagent, the health data management system estimates the temperature of the reagent from the measurement of ambient temperature provided by the temperature sensor, and the health management system determines the analyte concentration of the user, and wherein a weak thermal coupling between the housing portion and the cap minimizes heat transfer therebetween so that the cap maintains a cap temperature that is closer to the ambient temperature than the housing portion.
