Definitions
- Diabetes mellitus is a disease characterized by elevated levels of plasma glucose.
- Uncontrolled hyperglycemia is associated with increased risk of vascular disease including, nephropathy, neuropathy, retinopathy, hypertension, and death.
- diabetes There are two major forms of diabetes. Type 1 diabetes (or insulin-dependent diabetes) and Type 2 diabetes (or noninsulin- dependent diabetes).
- Type 1 diabetes or insulin-dependent diabetes
- Type 2 diabetes or noninsulin- dependent diabetes
- the American Diabetes Association has estimated that approximately 6% of the world population has diabetes.
- the goal of diabetic therapy is to maintain a normal level of glucose in the blood.
- the American Diabetic Association has recommended that diabetics monitor their blood glucose level at least three times a day in order to adjust their insulin dosages and/or their eating habits and exercise regimen. While, glucose tests can only measure a point in time result and do not provide an overall assessment of glycemic control over a period of time, it is an important tool in diabetes care management.
- Integrated cell phones with glucose testing capabilities have been developed.
- a significant drawback to these integrated devices is that they do not provide the opportunity to upgrade glucose hardware or meter functionality without replacing the entire phone.
- the entire device must be replaced to regain full functionality.
- the iPhone® and iPod® Touch offer superior graphics and data display capability potential, along with the flexibility of unlimited applications to manage data and communications.
- Glugophones are currently offered in at least three forms: as a dongle for the iPhone, an add-on pack for LG model UX5000, VX5200, and LX350 cell phones, as well as an add-on pack for the Motorola Razr® cell phone. This further limits providers to AT&T for the iPhone and Verizon for the others. Similar systems have been tested for a longer time in Finland.
- Module adaptable to communicate with a suitable handheld devices or PDAs.
- Suitable devices include, but are not limited to, the Apple iPhone® or iPod®, Research in Motion Blackberry® smart phones, Motorola Droid smart phones, and Palm Pre smart phones.
- the module can be used without adding to the cost of the handheld device. This allows direct reimbursement for the replaceable meter module portion if payers choose to limit coverage for the full system, as well as the possibility of reimbursement for the entire system including the handheld device.
- Other solutions build the cost into the phone, which must be replaced to upgrade or replace the glucose function.
- information from the glucose meter reading can be communicated from the PDA to a remote station for reporting the results. With an iPod- like approach, this could be accomplished without the need for a cellular signal or carrier, as long as a WiFi internet connection is available anywhere in the world.
- the glucose device described here is an attachment module using the standard connector interface of the handheld device.
- a single module could be used on multiple handheld devices, saving cost.
- This flexibility also means that the module could be used with a handheld device, such as an iPod, in the gym, or with a handheld device, such as an iPhone, in the office, etc. Since it is detachable, it does not require extra space or size in the handheld devices itself— it is only attached when a reading is required. It also does not add cost to the handheld device hardware, unlike the integrated units.
- the functionality of the module could range from a simple electronic interface to the strip (using the handheld device to do all calculations, data processing, display, and communications with health care providers or data services) to an interface plus glucose calculation engine (where the module delivers an answer, and the handheld device provides further data processing, display, and communications with health care providers or data services) to a fully contained meter with a small display, using the handheld device for much richer data processing, display, and communications.
- An aspect of the disclosure is directed to an apparatus for use to determine blood glucose levels.
- the apparatus comprises: an aperture adapted and configured to receive a glucose test strip; a detector adapted and configured to detect at least one of a presence or amount of a substance indicative of glucose level; a connector adapted and configured to engage the first device; a power source; and one or more input buttons or touch screen controls wherein the apparatus further comprises a logic apparatus adapted and configured to read instructions from a computer readable storage media associated with at least one of a first device having connectable to the Internet and the apparatus, wherein the computer readable storage media is configured to tangibly store thereon computer readable instructions.
