The cost and complexity of the feature is often incurred in the module itself. Additionally, users can select which features they want by purchasing and utilizing the module(s) of their choice.
The modules described herein include both passive modules and active modules that are hot swappable by the end user. Generally, passive modules are modules that are primarily mechanical in nature and do not contain electronics. Passive modules include, but are not limited to, a container for test strip storage or lancet storage and a lancing device with a space for lancet storage and/or disposal. Other passive modules include, for example, modules that contain hand sanitizer, paper logbook and/or pen, a medicine bottle, a glucose tablet bottle, rain/water cover (pull out and zip, similar to a hidden hood on a jacket), and any other modules having mechanical features that may be contained within the module and inserted into a slot in a meter.
In general, active modules are modules that include internal electronics with or without their own power supply. Active modules include, for example, a flashlight. A flashlight may be used for illuminating the patient's testing equipment in low light conditions. Other active modules include modules for wireless or wired connectivity including, but not limited to, Bluetooth/Bluetooth Low Energy, WiFi, Zigbee, USB, Ethernet, serial/RS-232, memory card/storage (mass storage device), GSM modem (or similar cellular phone connection), and other modules that can be used to establish a wireless or wired connection. For example, an active module can obtain a key (e.g., a private key) for use in communication with a computing device. The module can obtain the key by, for example, generating the private key (e.g., via a random or pseudorandom key generator), receiving the private key as input from a user, and/or reading the private key (e.g., via a scanning mechanism). In one embodiment, the active module can then pair with the computing device via a wireless communication medium, such as radio frequency (RF), such as WiFi, Bluetooth®, Bluetooth Smart®, ANT/ANT+®, ZigBee®, cellular, Near Field Communication (NFC), optical (e.g., barcode, IRDA, OCR, or similar devices), sound (e.g., ultrasonic, subsonic/vibratory, or similar sounds), magnetic, thermal, electrical (e.g., resistance, impedance, voltage, current) or similar channels. The active module can then finalize the pairing with the computing device.
Active modules may also include talking or audio modules to announce the blood glucose value to the user, as well as instruct a user through the testing process. Other active modules include, but are not limited to, modules with their own display, such as a carbohydrate counting module with buttons and a small LCD to show the total carbohydrates, scanners such as bar code scanners (to read strip lot codes or patient identification and import carbohydrate or other nutritional information from food packages), activity monitors (pedometers or other accelerometer type activity monitors), a calorie counter, an insulin pump controller, an insulin/carbohydrate calculator, a pulse oximeter (to check pulse and oxygenation), an emergency beacon/alert, a GPS, a Peak Flow meter, an additional analyte test adapter (cholesterol, ketone, HbA1c, Liver Enzyme, hematocrit, anemia, cardiac marker), and any other desired features using electronics.
In an embodiment, the active module may use its own battery rather than relying on the meter battery. In an embodiment, the active module has its own battery and can function when not inserted in the module.
Also, the active modules may include a LED light or other indicator to show use of one or more features of the active module. Active modules may also include a button to activate a function of the active module. If an active module includes more than one feature or function, then the active module may include one or more buttons for controlling those features or functions.
