Abstract
A low-profile placemat unit 1, for measuring and differentiating cumulative glycaemic and carbohydrate content of each food type at mealtimes to enable visual feedback of the amount of insulin to administer. A strain gauge or load cell is used to weigh food on plate 2. Data may be entered via keypad and displayed by LCD or OLED. A computer stores in memory information relating to carbohydrate content or ratio, blood sugar levels, food type or other relevant information for a diabetic diet.

Technical Field
Embodiments of the invention relate generally to the field of medical devices and, specifically, to methods, apparatuses, and systems associated with analysing and/or displaying carbohydrate quantity of about to be consumed food in order to determine the quantity of insulin to be administered.
background
This invention enables subjects with Diabetes to accurately calculate the amount of insulin to be administered based on carbohydrate consumption during meals.
To maintain long-term health and reduce the onset of other complications such as ketoacidosis, hyperosmolar syndrome, damage to nerves and blood vessels, it is important that those with this condition are able to maintain their blood sugar level between the values of 4 rnrnols (milli-moles) and 8 mmols.
Insulin is injected to match the amount of carbohydrates consumed during a meal. The amount of carbohydrate / sugars consumed during a meal is variable. Basic estimation techniques rarely estimate the correct quantity of carbohydrate and as a consequence, incorrect doses of insulin are administered.
Statement of Invention
A thin table placemat that supports a user's dinner plate, mass of the plate and contents being measured by a load cell or strain gauge.
The load-cell or strain gauge is interfaced to a micro-controller, keypad and screen integral within this device to enable the user to; * Select food types / menus or composite meals (meals where it is not possible to separate ingredients) * Notify the device when specific named food is being added or removed from the plate.
* View the amount of carbohydrate consumed and the amount of insulin that should be administered at the end of the meal.
Advantages The Low profile of this invention enables the user to use this as though it were a regular placemat. The meal and plate for the meal would always be held on top of this device.
The use of this placemat is non-intrusive during mealtirnes & works flexibly as a tool for the user.
The placemat is able to derive the combined glycaemic index of the consumed meal to enable an insulin pump (if used) to be configured with the correct bolus profile.
The placerriat uses a iJSB connector that enables menu and food types to be downloaded into the placemat.
The Placemat has a lit display enabling the user to operate it in restaurants that have low lighting conditions.
The menu system on the placemat enables the user to add new foods onto their plate and new foods into their menu during mealtime. The advantage is that this accommodates greater flexibility at the mealtime.
If food is not consumed at the end of the meal -the placemat allows for the food to be removed & thus reduce the cumulative carbohydrate value.
Brief Description of the drawings
An example of the invention will now be described by referring to the accompanying drawings: * Figure 1 shows the placemat with plate position, screen and keypad indicated.
* Figure 2 shows the connection between the placemat and a regular home computer.
* Figure 3 shows an internal block diagram of this Invention.
* Figure 4 shows the workflow for operating this Invention.
* Figure 5 shows the screen display and navigation buttons and a view of the charging socket and Mini-LJSB socket.
Detailed Description
Referring to Figure 1: The placemat (1) is constructed out of a tough, light & washable material. Consists of three main components: (2) The weighing platform -this is where a dinner plate would sit. A strain gauge or load cell is mechanically attached to the underside of this plate to measure the weight of the food and the weight of the dinner plate.
There is a flexible seal between plate (2) and the placernat (1) . Plate (2) is flush.
(4) The screen. A backlit LCD or OLED graphical or text screen. Enables the user to navigate between menus, select food types and receive feedback on total carbohydrate consumption & the amount of insulin to administer. A flowchart of the menu operation can be found in figure 2.
(3) Navigation buttons. Flush with the top of the placemat are sealed to prevent ingress of fluid or food.
May be pressed to navigate the menus or select items on the menu.
Referring to figure 2, the placemat (6) may be charged via a USB cable (7), or may be interfaced with a home computer (8), enabling menus to be downloaded into the placemat.
Referring to figure 3, the placemat contains the following; 1. A rechargeable battery -charged via the socket on the side of the placemat.
2. Circuit board: Containing microprocessor (5) and analog to digital converter (2) to converting the load cell voltages into data that can be read by the microprocessor. The microprocessor memory contains the food types (.e.g. potatoes, baked beans etc) and the amount of carbohydrate per lOOgrams of food type and the glycaemic index of each food type.
3. Screen: Either backlit LCD or OLED display (3) Connected to the microprocessor via a parallel or serial link to provide visuals such as menus, graphs or instructions to the end-user.
4. Load cell or strain gauge (1) for measuring the increments of food added.
5. Keypad (4) to control menu and actions.
6. tJSB Interface/connector (6) to enable the menus to be updated, or firmware to be updated via a home PC or Laptop.
Figure 4 shows the workflow or process involved when operating the device.
Figure 5 shows a number of views of the original prototype showing screen, buttons & interfaces.
Claims (11)

A graphic or text based screen to provide visual feedback on actions and computed results.
- 2. A device according to claim 1, in which each food item is able to be weighed independently of any other food by calculating the delta between tare weight and food incrementally added to the dinner plate.
- 3. A device according to claim 1, in which carbohydrate values may be electronically stored and associated with each food type to enable the total carbohydrate content of a meal to be calculated and visualised during use.
- 4. A device according to claim 1, in which a food type can be removed from the dinner plate allowing the microprocessor to subtract the proportion of carbohydrate from the running total.
- 5. A device according to claim 1, in which Glycaemic Index values stored within the said device allow the user to be provided a graphical representation of carbohydrate absorbsion rate for all food consumed in a single sitting.
