Integrated glucose monitoring system

A device, comprising:

• a handheld housing;
• an open cavity formed within the handheld housing;
• a mobile device positioned at least partially within the open cavity and removably connected to the handheld housing, wherein the mobile device is seated and retained at least partially within the open cavity with a retaining feature formed at the open cavity;
• a substantially closed cavity formed in the handheld housing proximate the open cavity;
• a glucometer positioned within the substantially closed cavity, the glucometer including:
• a device connecter at least partially extending into the open cavity and being removably connected to the mobile device to physically and electronically connect the glucometer to the mobile device seated in the open cavity;
• a test strip port configured to receive a test strip that includes a sample of blood;
• and
• measurement electronics electronically coupled to the test strip port such that a test strip inserted into the test strip port is electronically accessible to the measurement electronics;
• a test strip aperture disposed at a first end of the handheld housing and aligned with the test strip port for receiving the test strip to the test strip port through the test strip aperture;
• a cooling vent formed in the handheld housing and connected to the substantially closed cavity to vent air across the measurement electronics;
• an internal temperature sensor positioned within the handheld housing and electronically coupled to the measurement electronics;
• an external temperature sensor exposed to an exterior of the handheld housing and electronically coupled to the measurement electronics, wherein the measurement electronics include a processor programmed to adjust a blood glucose reading based on one or more of an ambient temperature reading taken by the external temperature sensor or an internal temperature of the substantially closed cavity taken by the internal temperature sensor approximately concurrently with the blood glucose reading;
• and
• a heat sink positioned approximate to the cooling vent such that the heat sink radiates, through the cooling vent, heat drawn away from the measurement electronics.
