Description
GLUCOMETER AND METHOD FOR USE
FIELD OF THE INVENTION
The disclosure herein relates to the collection and management of medical data of diabetic patients. In particular, the disclosure relates to the transmission of collected blood glucose level information from a glucometer to a remote computing device, such as a mobile phone. It further relates to methods and systems for monitoring a supply of test media and facilitating ordering replacement test media, methods and systems for transmitting information between elements of the system, and methods and systems for administering a dose of insulin to a user.
BACKGROUND OF THE INVENTION
Diabetes is a metabolic disease characterized by high blood sugar, also called glucose, resulting from disruption in production of, or lack of proper response to, insulin, a hormone central to regulating carbohydrate and fat metabolism. It can cause serious health complications including heart disease, blindness, kidney failure, and lower-extremity amputations. These complications may be avoided through effective and efficient balance of sugar levels. The glucometers (also called a glucose meter) is one tool for reaching and maintaining an optimal balance of blood sugar.
Many glucometers use an electrochemical method, based on test media such as test strips. Test strips are a consumable element containing chemicals that react with glucose in a drop of blood used for each measurement. The test media are typically single-use elements which are sold in packages which must be replaced once they are all used. In addition, insulin pumps are a tool used to maintain an optimal balance of blood sugar by regulating the level of insulin in a user.
Typically, a user will measure his blood sugar, for example using a glucometer. Based on the measured blood sugar, he uses an insulin pump to administer an appropriate dose of insulin.
Transmission of medical data to remote care givers may be facilitated by a wired or wireless Internet connection in the home, using a USB cable connection, for example. However, collecting the glucose level data and transmitting is more complicated when a user is outside of his home. For example, the user may be a child at school, or a patient on travel. Unless the user

Alternative methods and materials similar or equivalent to those described herein may be used in the practice or testing of embodiments of the disclosure.
Nevertheless, particular methods and materials are described herein for illustrative purposes only. The materials, methods, and examples are not intended to be necessarily limiting.
Reference is now made to Fig. 1 showing a block diagram schematically representing selected components incorporated into a distributed system 100 for the gathering and remote management of glucose level data using a plurality of devices.
The distributed system 100 comprises a plurality of devices, such as medical measurement device 140, which may be, e.g., a glucometer, and remote computing device 150 (which may be, e.g., a smartphone or any other suitable device such as a communications device, and which may constitute an output device).

For example, the
- 15 -medical measurement device 140 may transmit medical data through the remote computing device 150. The data may thereafter be communicated to a remote caregiver 90, e.g., via a computer or handheld device, such as a smartphone.
It will be appreciated that while the present disclosure is largely directed toward examples wherein the medical measurement device 140 is a glucometer, and the medical data measured thereby is glucose level, any device configured to measure medical data may be provided without departing from the spirit and the scope of the present disclosure, mutatis mutandis. For example, the medical measurement device 140 may be or comprise a thermometer, a scale (measuring any one or more or weight, body fat, bone density, and body mass index), a pulmonary edema monitor, and/or be configured to measure blood oxygen level/saturation, heart rate, blood pressure, physical activity (e.g., a pedometer) and/or calories burnt.
It is noted that a user interface for using the remote computing device 150, such as a touch screen or the like, may serve both as input and output devices thereof.
Use of a touch screen may allow the screen to be larger without compromising the size of a separate input device such as a key pad. Furthermore, a touch screen input device may be easier to use for the untrained user as it may use easy to interpret icons rather than complicated text based instructions.

Outbound communications channel 170A (the terms "outbound" and "inbound" when used herein with reference to communication between the medical measurement device 140 and the remote computing device 150 are from the point of view of the medical measurement device) may be provided for communication from the medical measurement device 140 to the remote computing device 150, which may be connected to the network directly.
According to some optional and non-limiting modifications, an inbound communications channel 170B may be provided for communication from the remote computing device 150 to the medical device 140 such that the devices may be operable to synchronize data with one another.
The outbound communications channel 170A may be, e.g., an audio based communication channel. As such, the medical measurement device 140 may comprise a transmitter 142, such as a speaker configured to transmit an audio signal encoding data regarding the measured medical data (such as, in the case of a glucometer, blood glucose level) for storage, display, or other purpose. The remote computing device 150 thus comprises receiver 152, such as a microphone (e.g., an electromagnetic induction microphone, a dynamic microphone, a capacitance change microphone, a piezoelectric generation microphone, a light
- 16 -modulation microphone, a MEMS microphone, or combinations of the above) configured to receive the signal transmitted by the transmitter 142.
Optionally, the remote computing device 150 may be configured for sending measured medical data stored thereupon to a professional care giver 90 or uploading to a central repository 80 via a computer network 50. Optionally, the devices may communicate using protocols such as BLUETOOTH (i.e., one or more wireless technologies for exchanging distances over short distances using short-wavelength radio transmissions in the ISM band from 2400-2480 MHz as per the standards defined by the Bluetooth Special Interest Group), NEAR FIELD
COMMUNICATION (i.e., one or more technologies for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, for example based on standards including, but not limited to, and those defined by the NFC Forum), WI-FI (i.e., one or more wireless local area network products that are based on the Institute of Electrical and Electonic Engineers' 802.11 standards), or any other suitable protocol.
The remote computing device 150 may be pre-loaded with an application 160, which facilitates, inter alia, locally viewing and/or analyzing the data measured by the medical measurement device 140.
The application 160 may be configured to send information regarding the measured medical data to a pre-defined recipient list. Such a list may include medical professionals, care givers, parents, and the like. It may store data with a time stamp, so that the measurement data may be provided within a historical context. For example, it may be configured, based on the time-stamped data to graphically present multiple results showing how measured data vary over time.
It is noted that the particular architecture and functionality as described hereinafter, by way of example, refer to a one-way communication protocol between the medical measurement device 140 and the remote computing device 150 via the outbound communications channel 170A. By employing only the outbound communications channel 170A, the medical measurement device can be provided without a receiver, thereby lowering its cost.
Optionally, it is assumed that while using a one-way communication protocol the transmission from the medical measurement device 140 may be repeated until a predefined event occurs. This event may be, for example, a test medium being removed from the medical measurement device 140, activation of a button or similar switch on the medical measurement device (in such a case, the application 160 may be configured to indicate to a user when it has

Furthermore, the medical measurement device monitor 140 and the remote computing device 150 may be complementary interdependent modules, each of which relies on the other to perform the required operations it does not itself perform. For example, the medical measurement device 140 may not itself have a display unit and may only measure the medical data and transmit it. This may be done via a wireless signal. Additionally or alternatively, the medical measurement device 140 may connect to the remote computing device 150 via a cable with a mini/micro USB plug.

In the present example, the medical measurement device 140 is operable to measure and store information regarding a glucose level of a subject. It is also configured to transmit data regarding the information via outbound communications channel 170A. According to some non-limiting modifications, it may be configured to transmit the information as data using a wireless audio based communication protocol. The glucose level and related collected information may be sent to remote devices (not illustrated) used, e.g., by caregivers, parents, etc., or to be stored remotely in a central repository. The transmission may be configured to occur automatically, for example to a pre-defined set of devices, and/or may be initiated manually.
The medical measurement device 140 includes a central processing unit (CPU) constituting a controller, a media reader 222 (for example a test strip reader), a power source 224, a transmitter 142, and a media slot 232. Optionally various other internal elements may be added, such as memory 228 and a micro USB port 230.
As mentioned, the medical measurement device 140 may have a primary function to measure the blood glucose level of a subject. Accordingly, the user may introduce a test medium 234 into the media slot 232 for reading by the media reader 222. Various test media 234 may be used with the medical measurement device 140 as known in the art. For example, test media may be plastic or paper strips impregnated with glucose sensitive chemicals such as glucose oxidase. The strips themselves may have various shapes as required. As known in the art, a subject typically applies a drop of blood to a test medium 234 before introducing the test medium 234 into the medical measurement device 140. The introduction of the test medium 234 into the medical measurement device 140 initiates a process which includes reading the media, calculating the glucose level, and transmitting the glucose level via outbound communications channel 170A to the remote computing device 150.

- 18 -According to some modifications, the medical measurement device 140 also transmits via outbound communications channel 170A information regarding one or more aspects of itself and/or of the test medium. Such information may include, but is not limited to, the battery level of the medical measurement device 140, calibration data, and/or information regarding specifics of the test medium (model, etc.).
The CPU 220 of the medical measurement device 140 is configured to encode the information before it is transmitted. The encoding may employ binary data, e.g., with two different tones (or ranges of tones) each representing different binary digits, or non-binary, e.g., with several tones (or ranges of tones) being used, each representing a non-binary digit. For example, hexadecimal encoding may be used, with 16 different tones (or ranges of tones) being used, each to represent a digit between Ohõ and Fhõ. In addition, data compression may be employed, wherein a tone contains more than one bit or data. Alternatively, the information may be sent as an analog signal, for example by "speaking" the information, i.e., by producing sounds mimicking human speech. According to any of the above, the audio signal may be within the range of human audible frequencies, or outside of it.
The CPU 220 is further configured to direct operation of the various elements of the medical measurement device 140, for example the media reader 222 and the transmitter 142.
It will be appreciated that although the CPU 220 is described herein and with reference to the accompanying figures as a single element, it may comprise several elements working together to perform the functions thereof. In addition, some of the functionality thereof may be performed by other elements listed herein (e.g., encoding may be performed by the same element which functions as the transmitter 142). In such a case, the CPU 220 is considered to comprise the elements which perform the functions of the CPU, despite the fact that they are physically located with other elements, mutatis mutandis.
According to some examples of the presently disclosed subject matter, the transmitter 142 comprises an audio-based communicator, such as a speaker, operable to transmit audio signals. The application 160 running on the remote computing device 150 is operable to detect the transmitted audio signals, for example via the receiver 152 thereof. The software application may further be configured to decode the information carried by the audio signals and display the measured glucose level on a display of the remote computing device.
Optionally, the application 160 may additionally be configured to enable automatic external communication of the measured glucose level to a pre-defined list of recipients, or manually communicate the measured data to a desired communicator.

Optionally, the medical measurement device 140 may include an internal memory for storing recorded data which may be accessed later. The medical measurement device may include a micro USB port 230 that may be connected to another device via mini/micro USB
cable. The micro USB port may provide dual functionality of charging the power source 224, if the power source is a rechargeable battery and connectivity to the processor 220 for downloading measured information.
It is noted that various graphical user interfaces (GUI) for analyzing the measured glucose information may be used as required, through the application 160 of the remote computing device 150.
According to some modifications of the presently disclosed subject matter, a display is provided in the medical measurement device 140. This display may thus serve as a user interface, for example comprising a touch screen using where appropriate, numerals or text that may be input either via a virtual keypad (not shown) or adjusted using adjustment arrows (not shown), operable to receive user input to configure transmission parameters for sending measured glucose level over the communication channel.

Reference is now made to Fig. 2B, showing a representation of an audio communication system 200' in which a medical measurement device 140 is communicating, using the outbound communications channel 170A described above with reference to Fig. 1, with the remote computing device 150, installed with application 160 for analyzing received glucose data. The glucose level and related collected information may be stored into a record, as described below with reference to Fig. 4, and transmitted to the remote computing device 150 for management and viewing thereof, and optionally for further transmission to caregivers, parents, etc., or to be stored remotely in a central repository.
The medical measurement device 140 may be configured to transmit a record automatically, for example upon introduction of a test medium. Alternatively, or additionally, transmission may be initiated manually by a user, for example via an activation button (not shown) on the device. Transmission signals may be repeated at regular time intervals at a pre-

Accordingly, according to some modifications of the presently disclosed subject matter, the medical measurement device could be provided free of elements which facilitate its receiving input from the remote computing device. This simplification may serve to lower the price of the medical measurement device 140 and/or increase its battery life.
The communication system representation 200' includes the medical measurement device 140 comprising a transmitter 142, a remote computing device 150, constituting a remote output device, such as a smartphone installed with a suitable software application 160 for analyzing the glucose level data, and glucose level data records 206.
It may further be noted that the medical measurement device 140 may be pre-configured to send data signals such as medical content signals or power level notifications at regular time intervals, for example, every 4 seconds. Such data may be received by the associated software application 160 running on the remote computing device 150.
Reference is now made to Fig. 3, which schematically represents possible elements for creating a record structure for transmission from a medical measurement device, using the wireless audio based communication protocol. The protocol is presented for illustrative purposes only, it will be appreciated that other protocols may occur to those skilled in the art and may be alternatively or additionally utilized.
The communication transmission elements includes a synchronization sequence 310, a bit of '1' representation 320 and a bit of '0' representation 330. These basic elements enable transmitting, for example, a sample level value of 5 ('101' binary sequence), for example, as presented in the 340 representation.
The communication protocol may be based on sending a sequence of '0' (s) and '1' (s) bits for each measurement of information sent, with 'AB' used as a synchronization signal, `CDE' as an indication for '1' and `FGH' as an indication for '0', and may use the following frequency levels, for example:
= A = 4000 Hz; B = 4200 Hz; (may be used for synchronization) = C = 4400 Hz; D = 4600 Hz; E = 4800 Hz; (may be used for constructing bit '1') = F = 5000 Hz; G = 5200 Hz; H = 5400 Hz; (may be used for constructing bit '0') Every tone, an 'A', for example, may take 20 milliseconds of transmission.
Thus sending a signal of 'AB' may take 40 milliseconds of transmission and a synchronization signal of 'AB' + 'AB' may take 80 milliseconds, followed with the actual coded information.

Reference is now made to Fig. 4A, representing a possible audio communication transmission 400 of glucose level measurement information from the medical measurement
- 21 -device to a remote computing device, such as a mobile device, for example. The transmission starts with a synchronization signal 411 and ends with a cyclic redundancy check (CRC) 414, an error detection code for detecting errors in the transmitted data.
It may be noted that, according to some examples, the transmission is of one-way communication. As no acknowledgement signal may be sent back when one-way communication is used, it may be useful to send the data signal, for example including glucose level related information repeatedly, e.g., every 4 seconds. According to some modifications, the records and audio communication protocol may, use functionality and commands to acknowledge successful reception of the record by the receiver, configure record timeout, request record resend, etc.
The communication transmission 400 includes a synchronization signal 411, followed by blood glucose level data measurement 412, optionally with battery level data 413 and ended with an encoded CRC error detection sequence 414.
The synchronization signal 411 is of 4T (tones), and may include sending the 'AB' signal twice in a sequence using 2 bits. The blood glucose level measurement 412 may be within a range of 1 to 512 mg/di of 27T (tones) using 9 bits. The optional battery level information 413 may take a value of 0 to 15 volts, thus of 12T (tones) using 4 bits. This may be completed with CRC error detection using 9 bits. Thus, the whole transmission may need a total of 24 bits. The transmission may also be repetitive, every 4 seconds, for example, and may continue as long as the test medium is inserted in its slot of the medical measurement device.
Transmission of each tone may take 20 milliseconds.
As illustrated in Fig. 4B, in one example, a synchronization signal may be followed by a glucose level value, a battery level value and an error detection signal. A
sample transmission of an average glucose level of 72 mg/di ('01001000') with battery level of 6 (`110') may take the format:
'AB' + 'AB', `FGH' + `CDE' + `FGH' + `FGH' + `CDE' + `FGH' + `FGH' + `FGH', `CDE' + `CDE' + `FGH', CRC
where the leading string 'AB', 'AB' represents the synchronization signal, and the terminal value CRC represents the error detection.
The value of the cyclic redundancy check (CRC) for encoding the record by adding a fixed-length check value may be used for error detection and data integrity verification. It may be based on the remainder of a polynomial division or may take a simple format of repeating a value, for a single value record, such as the blood glucose level or sending the sum of the two

- 22 -values, for a record containing the blood glucose level and the battery level, such that in the example above the value 78, being the sum of 72 and 6, may serve as the error detection value.
Reference is now made to Fig. 5 illustrating selected data integrity actions which are indicated of a method for encoding and decoding a record. The record is constructed on the medical measurement device 140 by its CPU 220, after reading the glucose level information from the test medium and verified by a method on the application installed on the remote computing device 150.
According to the method flow, a cyclic redundancy check (CRC) block may be attached at the end of the glucose information record. The record may be composed using the CPU 220 of the medical measurement device 140, resulting in a record having a length of k bits (step 502). This record may include synchronization signal, followed with the measured blood glucose level by the media reader 222 of the medical measurement device140.
Optionally, the battery level may be added to the record. After assembly of the record for sending, a short block of check data, having possibly 9 bits, may be attached at the end of the constructed record (step 504). The record may repeatedly be sent from the medical measurement device transmitter 226 and speaker 142 of the medical measurement device 140, over a wireless audio based channel to the remote computing device 150, at preconfigured time intervals, for example every 4 seconds.
The record may be received by the communicator 160 receiver component 506, to enable decoding the attached data block by the application 160, for error detection and correction purposes. For example, a cyclic redundancy check may be used for error detection, and error correction codes (for example by including parity data) may be used for error correction. Once received, the information is decoded, using the attached CRC string to validate the record content (step 508), with a possible output of a record having a length of k bits 510, if the record was properly received.
It may be noted, that the form of cyclic redundancy check (CRC) may apply a customized verification of data integrity, such as attaching the actual transmitted value, if only the blood glucose level is sent, or the sum of the measured glucose level and the battery level, if both values are send.
Referring to the flowchart of Fig. 6A selected actions are indicated of a method for transmitting blood glucose level measured data and related information from the medical measurement device 140 to a remote computing device 150, such as a mobile device installed with a pre-installed application 160. The transmission of the glucose measured level data may be communicated over a wireless audio channel-based system as described hereinabove.

The record is constructed on the medical measurement device 140 by its CPU 220, after reading the glucose level information from the test medium and verified by a method on the application installed on the remote computing device 150.
According to the method flow, a cyclic redundancy check (CRC) block may be attached at the end of the glucose information record. The record may be composed using the CPU 220 of the medical measurement device 140, resulting in a record having a length of k bits (step 502). This record may include synchronization signal, followed with the measured blood glucose level by the media reader 222 of the medical measurement device140.
Optionally, the battery level may be added to the record. After assembly of the record for sending, a short block of check data, having possibly 9 bits, may be attached at the end of the constructed record (step 504). The record may repeatedly be sent from the medical measurement device transmitter 226 and speaker 142 of the medical measurement device 140, over a wireless audio based channel to the remote computing device 150, at preconfigured time intervals, for example every 4 seconds.
The record may be received by the communicator 160 receiver component 506, to enable decoding the attached data block by the application 160, for error detection and correction purposes. For example, a cyclic redundancy check may be used for error detection, and error correction codes (for example by including parity data) may be used for error correction. Once received, the information is decoded, using the attached CRC string to validate the record content (step 508), with a possible output of a record having a length of k bits 510, if the record was properly received.
It may be noted, that the form of cyclic redundancy check (CRC) may apply a customized verification of data integrity, such as attaching the actual transmitted value, if only the blood glucose level is sent, or the sum of the measured glucose level and the battery level, if both values are send.
Referring to the flowchart of Fig. 6A selected actions are indicated of a method for transmitting blood glucose level measured data and related information from the medical measurement device 140 to a remote computing device 150, such as a mobile device installed with a pre-installed application 160.

According to other examples, the glucometer 812 may be configured to transmit the information over a two-way communication channel, including, but not limited to, BLUETOOTH (i.e., one or more wireless technologies for exchanging data over short distances using short-wavelength radio transmissions in the ISM band from 2400-2480 MHz as per the standards defined by the Bluetooth Special Interest Group), NEAR FIELD COMMUNICATION (i.e., one or more technologies for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, for example based on standards including, but not limited to, ISO/IES 18092 and those defined by the NFC Forum), WI-FI (i.e., one or more wireless local area network products that are based on the Institute of Electrical and Electonic Engineers' 802.11 standards), ZIGBEE (i.e., one or more of a suite of high level communication protocols used to create personal area networks built from small, low-power digital radios based on the Institute of Electrical and Electonic Engineers' 802.15 standard), and/or other suitable protocols.
According to any of the above examples, the transmitter 822 comprises the necessary hardware to facilitate transmission. For example, in the case wherein the glucometer 812 is configured to transmit information over an audio-based channel, the transmitter 822 comprises a suitable speaker.

Alternatively,
- 31 -the glucometer 812 and remote computing device 814 may each be loaded with complementary software which together perform this task.
As illustrated in Fig. 11, the system 810, e.g., by running appropriate software (either installed on one of its constituent devices, or as complementary software on both), is configured to execute a method, which is generally indicated at 900. The method 900 may be executed in conjunction with the glucometer analyzing a test medium.
In step 910, a user utilizes the glucometer 812 to perform a blood analysis using a test medium, and the system 810 determines whether or not the medium being used for the analysis is the first one to be used from the package. According to some examples, the system 810 makes this determination based on user input, i.e., by prompting the user via the user-output interface 834 of the remote computing device 814, and/or by receiving an indication, which may be solicited (e.g., in response to a prompt) or unsolicited, as such by the user via the user-input interface 832.
According to other examples, the system 810 makes this determination automatically.
For example, it may determine this based on the previous analysis being performed on the last test medium in its package. Alternatively, it may determine this based on information encoded on the test medium (e.g., the batch number) differing from that of the medium used in the previous analysis. According to any of the above examples, the system 810 may require that an automatic determination made thereby be confirmed by a user.
It will be appreciated that the system 810 may be configured to make the determination in one of several ways. For example, it may be configured to use one or more automatic methods to make the determination, but also be configured to receive an unsolicited indication from a user.
If the system 810 determines in step 910 that the test medium used in the analysis is the first one used from its package, then it proceeds to step 920 of the method, wherein it initializes a counter, which tracks the number of test media remaining in the package, as follows: C = N-1, where C is the value of the counter, and N is the number of test media initially in the package. According to some examples, the value of N may be determined by prompting a user, via the user-output interface 834, for the number of test media in the package. According to other examples, the system 810, e.g., via the remote computing device 814, may be configured to scan a barcode, such as a one-dimensional or two-dimensional (sometimes referred to as "matrix") barcode, printed on the package, and associate information encoded therein with the quantity of test media within the package.

- 32 -Following step 920, the method terminates until the next analysis of a test medium is performed.
If the system 810 determines in step 910 that the test medium used in the analysis is not the first one used from its package, it proceeds to step 930 of the method 900, wherein it decrements the counter by one, i.e., C = C ¨ 1. In the event that more than one test medium was used in the analysis, or if several analyses were performed before the system decremented the counter, the counter is decremented accordingly. For example, if n test media were used in an analysis, the counter would decrement as follows: C = C ¨ n.
After decrementing the counter in step 930, the system 810 determines in step whether or not a predetermined threshold value T has been passed, i.e., if the counter is lower than the threshold (C < 7). The threshold value indicates at which quantity of remaining test media it is estimated that a new package should be ordered. The value may be based on the expected daily usage of test media, which may be provided by the user or determined by the system 810, for example based on usage history. In addition, the system 810 may take shipping times into account when determining the threshold value, and may further include a safety factor, for example determining the threshold value based on when an order should be placed to ensure that the user receive an ordered package several days before the current one is finished.
Alternatively, the system 810 may allow a user to set a threshold value manually.
If the system 810 determines in step 940 that the threshold value has been passed, it proceeds to step 950 of the method, wherein it initiates an ordering procedure. The ordering procedure may be any procedure which is designed to facilitate or otherwise directly contribute toward a package of media being ordered.
According to some examples, the ordering procedure comprises the remote computing device 814 ordering one or more new packages of media via the Internet from an Internet-based merchant. This may be performed by the remote computing device 814 automatically.
Accordingly, the remote computing device 814 and/or Internet-based merchant stores relevant information, e.g., shipping address, product to be ordered, etc. According to some modifications, the remote computing device 814 and/or Internet-based merchant may further store billing data, such as credit card information, billing address, etc. The remote computing device 814 may be configured to survey several ordering options for the best value. For example, it may check several Internet-based merchants for the best price for a particular product, it may check for the best unit price (i.e., cost per test medium) among several equivalent products, either at a single or at several Internet-based merchants, etc., and order from the one which provides the best value. In addition, in may be configured to take a preselected action if it identifies an unusually

In addition, in may be configured to take a preselected action if it identifies an unusually
- 33 -good value, for example as preset by the user. The preselected action may be one or more of, but is not limited to, ordering an increased quantity of packages and alerting the user that it identified the value. The user may preset what he considers to be a good value, for example more than a certain percentage lower per test medium than past purchases. The past purchases may be, e.g., an average or absolute best value of a predetermined number of last purchases, or an average or absolute best value of purchases made over a preselected amount of time.
According to other examples, the ordering may be a manual process, wherein the ordering procedure comprises alerting the user that the system 810 has determined that an order should be placed for a replacement package of test media. The remote computing device 814 may optionally present information and/or direction to facilitate the ordering by the user. For example, it may present on its user-output interface 834 one or more links, each redirecting a user to an Internet-based merchant which sells one or more packages of suitable test media.
According to further examples, some parts of the ordering may be automatic, as described above, with one or more manual steps. According to some modifications, the ordering procedure may comprise the remote computing device 814 automatically retrieving a website via which the user can purchase a package of test media. According to other modifications, the ordering procedure may comprise the remote computing device 814 retrieving all information necessary to place an order, e.g., product, price, merchant, estimate of shipping time, shipping address, billing address, billing information, etc., and presenting to the user for his approval, upon which the remote computing devices places the order accordingly.
The system 810 may utilize information regarding the ordering procedure in step 910, it may assume that the next package to be used is the one ordered, and initiate the counter C
accordingly. Optionally, the system 810 may prompt the user to confirm the number of test media in the package the next time the counter C is initiallized.
Following step 950, the method terminates until the next analysis of a test medium is performed.
If the system 810 does not determine in step 940 that the threshold value has been passed, the method 900 terminates until the next analysis of a test medium is performed.
It will be appreciated that the above represents a basic method 900 which the system 810 is configured to follow to facilitate ordering of replacement test media by the system 810 based on usage of test media by the glucometer. The method 900 may be modified without departing from the spirit and scope of the presently disclosed subject matter, mutatis mutandis.
For example, the method as presented above may be modified, mutatis mutandis, to account for a user who orders more than one package of test media at a time, in which case it
According to other examples, the ordering may be a manual process, wherein the ordering procedure comprises alerting the user that the system 810 has determined that an order should be placed for a replacement package of test media.

accordingly. Optionally, the system 810 may prompt the user to confirm the number of test media in the package the next time the counter C is initiallized.
Following step 950, the method terminates until the next analysis of a test medium is performed.
If the system 810 does not determine in step 940 that the threshold value has been passed, the method 900 terminates until the next analysis of a test medium is performed.
It will be appreciated that the above represents a basic method 900 which the system 810 is configured to follow to facilitate ordering of replacement test media by the system 810 based on usage of test media by the glucometer. The method 900 may be modified without departing from the spirit and scope of the presently disclosed subject matter, mutatis mutandis.
For example, the method as presented above may be modified, mutatis mutandis, to account for a user who orders more than one package of test media at a time, in which case it
- 34 -would be relevant to monitor the user's supply of test media, not just the media in one package.
It will be appreciated that in the case wherein the user maintains a supply of one package, the quantity of test media in a single package is equal to the user's supply.
Accordingly, the method 900 may be modified to add a second counter which monitors the number of complete packages of test media which have been used besides the number of test media remaining in the current package. For example, the counter C may be initialized to be the total number of test media the user purchases (for example, if the user orders 3 packages, each containing 850 test media, the value in step 910 of N would be 150). Alternatively, the method 900 may include an additional counter which monitors the number of packages of test media. Alternatively, the counter C may initially be set to the total supply of test media, for example by prompting the user for relevant information regarding his supply.
In addition or alternatively, the counter C may start at 0 or 1, and increment, with the threshold being passed in step 940 if the counter is higher than the threshold, i.e., C < T.
Furthermore, the numerical operations presented herein may be shifted (e.g., in step 940, the system may determine that the threshold has been reached, i.e., that C = T; in step 920, the counter may be initialized as C = N; etc.).
According to a further example, as illustrated schematically in Fig. 12, there is provided a system, which is generally indicated at 1010, for measuring the glucose level of a user. The system 1010 comprises a glucometer 1012 and a remote computing device 1014.
As illustrated schematically in Fig. 13, the glucometer 1012 comprises a processor 1016, one or more memory modules 1018 (which may comprise volatile and/or non-volatile memory), a media reader 1020, a visual display 1022, and a power source 1024. In addition, it may optionally comprise other elements (not illustrated), such as an external memory reader, a transmitter, one or more ports configured for connection to a data cable, etc.
The media reader 1020 is configured to facilitate analyzing a blood sample disposed on a test media (not illustrated), such as a test strip, disc, drum, cartridge, or any other suitable medium. It may be designed so as to facilitate detecting the glucose level in the blood sample using any suitable method. For example, in an electrochemical method, the blood sample reacts with one or more chemicals impregnated on the test medium. The amount of products of the reaction is proportional to the glucose level in the blood, and can be measured electrically by the media reader 1020. Alternatively, the media reader 1020 may operate using a coulometric or amperometric method, as is known in the art.
In addition, the media reader 1020 may be configured to read information encoded on the test medium, including, but not limited to, calibration information, information regarding the
It will be appreciated that in the case wherein the user maintains a supply of one package, the quantity of test media in a single package is equal to the user's supply.
Accordingly, the method 900 may be modified to add a second counter which monitors the number of complete packages of test media which have been used besides the number of test media remaining in the current package. For example, the counter C may be initialized to be the total number of test media the user purchases (for example, if the user orders 3 packages, each containing 850 test media, the value in step 910 of N would be 150). Alternatively, the method 900 may include an additional counter which monitors the number of packages of test media.

In addition or alternatively, the counter C may start at 0 or 1, and increment, with the threshold being passed in step 940 if the counter is higher than the threshold, i.e., C < T.
Furthermore, the numerical operations presented herein may be shifted (e.g., in step 940, the system may determine that the threshold has been reached, i.e., that C = T; in step 920, the counter may be initialized as C = N; etc.).
According to a further example, as illustrated schematically in Fig. 12, there is provided a system, which is generally indicated at 1010, for measuring the glucose level of a user. The system 1010 comprises a glucometer 1012 and a remote computing device 1014.
As illustrated schematically in Fig. 13, the glucometer 1012 comprises a processor 1016, one or more memory modules 1018 (which may comprise volatile and/or non-volatile memory), a media reader 1020, a visual display 1022, and a power source 1024.

In addition, the media reader 1020 may be configured to read information encoded on the test medium, including, but not limited to, calibration information, information regarding the
- 35 -make and/or model of the test medium, and information regarding the manufacturing of the test medium (such as batch number, manufacture date, expiration date, etc.).
The processor 1016 is configured to direct operation of the elements of the glucometer 1012. As such, it may be configured to facilitate analysis of the blood sample, encode information measured by the media reader 1020 for display by, and direct operation of, the visual display 1022, etc. In performing these tasks, it may utilize the one or more memory modules 1018 for short-term storage of information.
The visual display 1022 comprises one or more elements configured to visually present encoded data. It may comprise, e.g., one or more LEDs (for example multi-color LEDs, i.e., being configured to selectively produce light of different colors), a screen, such as LCD, LED, OLED, plasma display, ELD, electronic paper, or electronic ink, or any other suitable display elements. In addition, it may comprise a combination of two or more different display technologies.
As mentioned, the processor 1016 is configured to facilitate displaying of encoded information regarding the results of the analysis by the visual display 1022.
The encoding may be accomplished by any suitable method. The method of displaying of the encoded results is dependent on the type of visual display 1022.
The results may be encoded as a sequence of visual elements. For example, according to a modification wherein the visual display 1022 comprises one or more LEDs, the information may be encoded and displayed as a time sequence of on/off states of the LEDs.
In addition, different colors may be used to encode values of data. (For example, a multi-color LED may encode two bits of binary data in a single flash thereof, wherein each of four different colors indicates one of 00, 01, 10, and 11.) In addition, different durations of a flash may indicate different values. Combinations of the above may be employed, wherein the value transmitted by an LED depends both on the color and duration of its flash. According to some modifications, the visual display 1022 comprises several LEDs, wherein the processor 1016 is configured to transmit data separately via each LED simultaneously, jointly using all LEDS
as a single data channel, or in combinations thereof.
The results may be encoded as a pattern. For example, according to a modification wherein the visual display 1022 comprises a screen, the processor 1016 is configured to encode the information and direct the visual display 1022 to present it as alphanumeric characters, for example as illustrated in Fig. 14A. According to other modifications, the processor 1016 is configured to encode the information and direct the visual display 1022 to present it as a barcode, e.g., as a one-dimensional barcode (an example of which is illustrated in Fig. 14B) or a
