Power management system for a handheld medical device

摘要

A system for managing power consumption of a handheld diabetes management device and limiting effects of temperature on operations performed by the handheld diabetes management device comprises a blood glucose measuring module, a temperature sensing module, and a power management module. The blood glucose measuring module selectively measures blood glucose in a blood sample and generates a status signal indicating a status of operation of the blood glucose measuring module. The temperature sensing module senses an internal temperature of the handheld diabetes management device and estimates an ambient temperature external to the handheld diabetes management device. The power management module deactivates one or more components of the handheld diabetes management device based on the status of operation of the blood glucose measuring module when the internal temperature of the handheld diabetes management device exceeds a threshold temperature. The power management module deactivates the blood glucose measuring module when the ambient temperature is greater than a first predetermined threshold or less than a second predetermined threshold.

主权项

1. A system for managing power consumption of a handheld diabetes management device and limiting effects of temperature on operations performed by the handheld diabetes management device, the system comprising:
a temperature sensor that senses an internal temperature of the handheld diabetes management device; a port that externally receives a removable measurement strip having a reaction site for receiving a blood sample; a thermal modeling module that uses a thermal model to estimate an ambient temperature proximate to the reaction site based on the internal temperature; and a power management module that deactivates one or more components of the handheld diabetes management device when the ambient temperature proximate to the reaction site exceeds a threshold temperature, wherein the one or more components include; a first communication module that communicates with a first device external to the handheld diabetes management device using a first communication protocol, wherein the first device performs a first function associated with a patient, and wherein the first function has a first priority, and a second communication module that communicates via a wireless communication link with a second device external to the handheld diabetes management device using a second communication protocol, wherein the second device performs a second function associated with the patient, and wherein the second function has a second priority that is lower than the first priority, wherein the power management module deactivates the second communication module before deactivating the first communication module, and wherein the first communication module and the second communication module are located within the handheld diabetes management device.
