BATTERY STATUS DETECTION AND STORAGE METHOD AND SYSTEM IN MEDICAL MONITORING

摘要

Described herein are systems and methods to determine when a new or fresh battery has been replaced in a medical monitoring device and store a record of such battery replacement so that the battery records of the medical monitoring device can be reliably kept over the life of the monitoring device.

1. A method of monitoring power in a portable physiological measurement device that has at least a battery coupled to a processor and memory, the method comprising the step of:
turning on the device; measuring with the microprocessor power of the battery; determining if the power level of the battery is greater than a first threshold; if the power level is less than or equal to the first threshold then setting a flag for low battery as true otherwise performing start up checking process of the device; after the performing of the startup checking process, evaluating the battery to determine if both the power level of the battery is greater than a second threshold and the low battery flag is set as true; if the evaluating step is affirmative then recording the time and date of the evaluating step to memory and setting the flag for low battery as false and annunciating a status of the battery in the device; if the evaluating step is negative, then conducting an analyte measurement; checking the power level of the battery against the first threshold; if the checking indicates that power level is greater than the first threshold then annunciating a result of the physiological measurement otherwise ending the checking step.
