A portable insulin injection pen and blood glucose monitoring device is integrated into a single unit for testing and treating diabetes symptoms. The device has a housing of a size suitable for transport in a users clothing pocket or handbag. Within the housing is a blood glucose monitoring system for receiving a sample of the users blood and detecting its glucose level, an insulin injection mechanism for administering an insulin injection, and a microprocessor that calculates an insulin dosage appropriate to the detected blood glucose level and sets the insulin injection mechanism to administer the calculated insulin dosage. A communication device automatically informs a remote emergency service provider, such as 911 or an emergency service to which the user has subscribed, if the microprocessor determines that the detected blood glucose level presents a potential danger to the user. The microprocessor also calculates treatment regimens specific to a particular user based on the detected blood glucose level and displays the treatment regimens on an LCD display. In a particularly advantageous embodiment, a GPS receiver within the housing detects the location of the device, and the communication device, which can be a cellular telephone separate from the housing connected wirelessly to the unit via a Bluetooth connection or cellular telephone circuitry within the housing itself, transmits information regarding the location to the remote emergency service.La présente invention concerne un stylo dinjection dinsuline portable et un dispositif de surveillance de glycémie qui est intégré dans une unité unique pour soumettre à essai et traiter des symptômes du diabète.
