As the number of patients suffering from diabetes and similar medical conditions increases, self-monitoring of blood glucose wherein the patient monitors his or her blood glucose levels has become a common practice. The purpose of monitoring the blood glucose level is to determine the concentration level and then to take corrective action, based upon whether the level is too high or too low, to bring the level back within a normal range. The failure to take corrective action can have serious medical implications. Glucose monitoring is a fact of everyday life for diabetic individuals. Failure to test blood glucose levels properly and on a regular basis can result in serious diabetes-related complications, including cardiovascular disease, kidney disease, nerve damage and blindness.
People with diabetes who intensively manage their blood sugar experience long-lasting benefits. The Diabetes Control and Complications Trial (DCCT) was a clinical study conducted from 1983 to 1993 by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). The DCCT compared intensive to conventional treatments. Patients on intensive treatment kept glucose levels as close to normal as possible with at least three insulin injections a day or an insulin pump, and frequent self-monitoring of blood glucose. Intensive treatment aimed to keep hemoglobin A1c (HbA1c), which reflects average blood glucose over a 2- to 3-month period, as close to normal as possible. Intensive treatment aimed to keep hemoglobin A1c (HbA1c), which reflects average blood glucose over a 2- to 3-month period, as close to normal as possible. Conventional treatment consisted of one or two insulin injections a day with once-a-day urine or blood glucose testing. The results of the DCCT study showed that keeping blood glucose levels as close to normal as possible slows the onset and progression of eye, kidney, and nerve diseases caused by diabetes. In fact, it demonstrated that any sustained lowering of blood glucose helps, even if the person has a history of poor control.
A number of glucose meters are currently available that permit an individual to test the glucose level in a small sample of blood. Many of the meter designs currently available make use of a disposable test element which in combination with the meter measures the amount of glucose in the blood sample electrochemically or optically. In current glucose meters, the information displayed as a consequence of a successful blood glucose measurement is the respective blood glucose value, typically shown in mg/dL or mmol units, and perhaps the time and date the measurement was performed. This information in combination with calculation of planned or known intake of carbohydrates or planned or known activities and knowledge of other situational or individual factors is in most cases sufficient to allow diabetics to adjust or derive their dietary intake and/or an immediate dose of insulin to inject to control blood glucose level on the short-term. Also, in case of low glucose values, diabetics can detect the need for intake of sugar to avoid hypoglycemia. Further, analysis of multiple blood glucose measurements taken over a period of time assists diabetes patients in determining what, if any, long term changes are necessary for their diabetes management routine. Given the ramifications of accurate recording, reporting and analyzing of blood glucose measurements, improvements in the apparatus and/or procedures to meter blood glucose are desired.

Such aspects can include, without limitation, the settings of display 24 or programming of processor 42. In another form, docking device 50 provides calibration data to bG meter 20. In this form, processor 42 is operable to process the calibration data and implement modifications or other appropriate actions which are necessary to properly calibrate bG meter 20 to ensure accurate bG measurements. In one form, the calibration data can include information regarding test strips 34 used by bG meter 20. As indicated above, processor 78 of docking device 50 is also operable to provide programming updates to bG meter 20 which are processed and implemented by processor 42.
Processor 78 of docking device 50 is also operable to create, arrange or modify the events that are scheduled in the calendar stored in memory 40 of bG meter 20 and memory 76 of docking device 50. In one form, a scheduler program is provided on docking device 50 that can be used to create a schedule that is uploaded onto bG meter 20 each time bG meter 20 is positioned in internal receptacle 64. Additionally, the schedule created by the scheduler program may also be stored in memory 76 of docking device 50. As a variation however, it is contemplated that the schedule stored in memory 76 of docking device 50 can be different from the schedule stored in memory 40 of bG meter 20. It should be appreciated that the schedule developed by the scheduler program can wholely replace an earlier schedule stored in memory 40, 76, or processor 42, 78 can be operable to make appropriate changes to the earlier schedule according to the later provided schedule.
In
Other variations in arranging the schedule stored in memory 40 of bG meter 20 are contemplated. For example, in one alternative, when bG meter 20 interfaces with docking device 50, the calendar stored in memory 40 of bG meter 20 can be produced on display 70. In this arrangement, user entry means 68 can be used to navigate through the calendar, store events and specify alarm settings as desired. Once the schedule is completed, it can be saved in memory 40 of bG meter 20. Moreover, it is also contemplated that processor 78 could be operable to carry changes made to the calendar stored in memory 40 of bG meter 20 over to the calendar stored in memory 76 of docking device 50.
Additional interaction between the calendars of docking device 50 and bG meter 20 is also contemplated. For example, in one form, the calendar of docking device 50 can be updated to reflect the user's performance, or lack thereof, of each of the events scheduled. In this form, in response to an alarm, a user can provide an indication with user entry means 26 to bG meter 20 that the event corresponding to the respective alarm was performed. Processor 42 is operable to store the indication in memory 40 and transfer the indication to docking device 50 when bG meter 20 interfaces therewith. Processor 78 of docking device 50 is operable to process the indication and associate it with a corresponding event entered in the calendar stored in memory 76. Processor 78 is further operable to provide on display 70 a modified representation of the calendar stored in memory 76 which indicates which events have been performed. As an example, the representation on display 70 could represent a diabetic's compliance with a bG testing schedule.
As indicated above, docking device 50 is also operable with bG meter 20 to analyze bG measurement data which is stored in memory 40 of bG meter 20. When bG meter 20 is positioned in internal receptacle 64 and interfaced with docking device 50, processor 78 is operable to process and record the bG measurement data stored in memory 40 of bG meter 20. The bG measurement data may be representative of each bG measurement taken by bG meter 20 over the period of time since the bG meter 20 was last interfaced with docking device 50. It is contemplated that the period of time could reflect hourly, daily, weekly, monthly or even longer intervals, just to provide a few examples. Processor 78 is operable to store the bG measurement data in memory 76 of docking device 50. Additionally, processor 78 is operable to provide a representation of the bG measurement data from memory 40 on display 70. In one variation, processor 78 is operable to aggregate bG measurement data from memory 40 along with other bG measurement data stored in memory 78 and provide a representation of the aggregation on display 70. The aggregation of bG measurement data can include all bG measurements taken within a period of time, such as a day, week or month. Additionally, display 70 could provide a representation of the aggregation of bG measurement data over each of these periods and user entry means 68 can be utilized to navigate and view each representation.
Graphical and textual representations of the bG measurement data on display 70 are contemplated. As used herein, a graphical representation may include one or more textual representations in combination with one or more graphical representations of or related to the data. The textual presentation may be included with the graphical presentation, or in one or more alternating displays of the graphical representation. In one embodiment, a graphical representation of bG measurement data is produced by processor 78 on display 70 so that the user is provided with a visual representation of the bG measurement data. If display of the bG measurements is desired, then the display thereof on display 70 may be produced immediately upon a single user interaction with entry means 68 indicating that the display is desired, or automatically after a pre-determined delay following the interface of bG meter 20 with docking device 50. Alternatively, the bG measurement data processed by processor 78 of docking device 50 can be accessed by a user through one or more menus provided on display 70 and navigated by user entry means 68.
It is contemplated that the graphical and textual representations of the bG measurement data produced on display 70 by processor 78 include any one or combination of xy-graphs, bar graphs, data plots, pie charts, or other suitable graphical representation to represent the bG measurements. In addition, the graphical or textual representations can be color coded to facilitate user interpretation of the results. For example, if one or more of the measured bG values is outside a recommended pre-defined range of blood glucose limits, the display can be presented with a warning indicator or in a warning color, such as red. If the one or more of the measured bG values is near or slightly above or below the pre-defined range of blood glucose limits, display 70 can be presented with a cautionary indicator or in a cautionary color, such as yellow. If all the associated bG measurements are within the recommended range, then display 70 can be presented with a satisfactory indicator or color, such as green. Further details regarding display and representations of bG measurement data are described in U.S. patent application Ser. No. 12/481,965, filed 10 Jun. 2008, the disclosure of which is incorporated herein by reference in its entirety.
In one embodiment, processor 78 is operable to perform additional functions in response to processing the bG measurement data stored on bG meter 20 or the bG measurement data stored on bG meter 20 in aggregate with other bG measurement data stored in memory 76 of docking device 50. For example, in one form docking device 50 includes an insulin bolus calculator and processor 78 is operable to determine a suitable insulin dosage with the insulin bolus calculator based on the bG measurement data. Dietary information which the user can enter and store in memory 76, further details of which are provided below, may also be considered when determining the insulin dosage. In this arrangement, docking device 50 may also provide bolusing instructions which correspond to the insulin dosage determined by the bolus calculator to one or more secondary devices, such as insulin delivery devices. Examples of insulin delivery devices include, without limitation, insulin pumps, pens and syringes. In one embodiment, docking device 50 can automatically provide the bolusing instructions to the secondary device(s) in response to determining the insulin dosage.
In another embodiment, processor 78 is operable to create a prompt on display 70 for the user to confirm that the bolusing instructions should be sent. The user can provide an input with user entry means 68 which confirms or cancels the bolusing instructions. In an alternative embodiment, the insulin dosage is not automatically determined by docking device 50. Instead, the user can use user entry means 68 to open and control the insulin dosage calculator and independently determine the appropriate insulin dosage. In a manner similar to that described above, the user can instruct docking device 50 to provide bolusing instructions to the secondary device that correspond to the appropriate insulin dosage determined by the bolus calculator. While not previously mentioned, it should be appreciated that docking device 50 can provide the bolusing instructions to the secondary device(s) through a wired or wireless connection.
Docking device 50 can interface with the secondary devices to determine and/or configure various operating aspects of these devices as well. For example, in one form, processor 78 is operable to regulate the rate at which the secondary device, such as an insulin pump, delivers the insulin dosage to a user of the pump. Processor 78 can also determine the date of expiration of the pump or the amount of insulin remaining in the pump and/or calculate the estimated amount of time left before the pump distributes the remaining insulin. It is also contemplated that processor 78 can provide an audible or visual indication of these aspects of the pump or some other secondary device to the user. Still, it is contemplated that processor 78 can perform other management and configuration functions relative to the secondary devices beyond those specifically set forth herein.
It is also contemplated that docking device 50 can store insulin delivery data, such as doses or dosage amounts. In one form, processor 78 is operable to store the insulin delivery data in memory 76 of docking device 50 according to the time and date when the insulin was delivered. When docking device 50 provides bolusing instructions to the secondary device(s) as described above, it is contemplated that the insulin delivery data is automatically stored in memory 76 when the bolusing instructions are provided to the secondary device(s). Alternatively, a user can independently provide input through user entry means 68 which is indicative of the insulin delivery data, regardless of whether docking device 50 provides bolusing instructions to the secondary device(s). Processor 78 may be further operable to provide textual and graphical representations of the insulin delivery data, which may include any one or combination of xy-graphs, bar graphs, data plots, pie charts, or other suitable graphical representation to represent the insulin delivery data. In one form, the textual and graphical representations could display insulin doses delivered over a daily, weekly or monthly interval, just to name a few possibilities. In yet a further embodiment, processor 78 is operable to compare the insulin delivery data with other information stored in memory 76, such as the bG measurement data, in a single graphical or textual representation.
In addition to the foregoing, it is contemplated that processor 78 could provide user advice in response to processing the bG measurement data. The advice could be in the form of an audible, visual or audio-visual presentation, just to name a few possibilities. The advice can indicate whether the processed bG measurements are outside a recommended range, within a recommended range, or moderately outside or approaching limits of a recommended range. The advice can also present a recommended action or course of actions to the user based on the bG measurement data. For example, if one or more of the bG measurements is severely outside the recommended range, the advice can recommend dietary changes and changes to insulin dosage per a doctor's advice. If one or more of the bG measurements is moderately outside the recommended range, then the advice can recommend dietary changes to assist the user in obtaining future bG measurements within the recommended range. The advice can also provide positive feedback to the user if the bG measurements are within the recommended range and no dietary or insulin dosage changes are needed.
Docking device 50 can also be operable to record, store, manage and organize information regarding the user's dietary and daily routines and other aspects of the user's health. As illustrated in
In a further embodiment, processor 78 is operable to access the information that is stored in memory 76 regarding the user's dietary and daily routines and other aspects of the user's health and generate an interactive diary log of such information. Processor 78 is also operable to display the diary log on display 70. It is also contemplated that insulin dosage information and bG measurement data can be incorporated into the diary log generated by processor 78. One example of a diary log displayed on display 70 is illustrated in
Processor 78 may be further operable to provide textual and graphical representations of the nutritional information stored in memory 76. For example, the representations could depict the amount of carbohydrates or calories that the user consumes within a period of time, such as a day, week or month, just to provide a few examples. The representations may include any one or combination of xy-graphs, bar graphs, data plots, pie charts, or other suitable graphical representation to represent the nutritional information. It is further contemplated that the representation could display the nutritional information in combination with one or both of the bG measurement data and the insulin dosage data recorded in memory 76.
It is also contemplated that docking device 50 could be provided with educational or training programs designed to assist the user in developing and following a diabetes management program. Among other things, the programs can provide basic educational information on diabetes, bG measuring and analysis, and the interplay between dietary habits and intake and proper diabetes management. In one form, the training programs can be provided in the form of a video. For example, as illustrated in
It is further contemplated that docking device 50 could be provided with audible assistance with data management, such as is described in one or more of the following U.S. Patent Application Publications, the disclosures of which are incorporated herein by reference in their entireties: US 2006/0277048; US 2008/0172235; and US 2008/0243758.
As indicated above, it is contemplated that bG meter 20 can be coupled with a PC. Additionally, docking device 50, either alone or with bG meter 20 positioned in internal receptacle 64, can also be coupled with a PC through a wired or wireless connection. The PC includes software which interacts with bG meter 20 and docking device 50 and is operable to perform one or more of the diabetes management functions that docking device 50 performs. For example, the software can process and record bG measurement data from bG meter 20, perform an analysis of the bG measurement data and provide an output, such as a graphical representation, of the bG measurement data. It is also contemplated that the PC software is operable to organize and modify the events scheduled in the calendar stored in memory 40 of bG meter 20 or memory 76 of docking device 50. Still, in further forms it is contemplated that the PC software is operable to configure one or more of the operating parameters of bG meter 20 or docking device 50. As an example, the PC software can provide updates to one or both of bG meter 20 and docking device 50 which are first downloaded onto the PC from the internet or some other electronic media, such as a CD or DVD. In addition to the foregoing, it is contemplated that the PC software can be operable to download information from docking device 50 and transfer it to appropriate health management related databases. For example, in one form it is contemplated that certain information stored on docking device 50 can be transferred to a relevant insurance database. In another form, it is contemplated that relevant information stored on docking device 50 can be downloaded into an electronic health record of the patient.
In a further embodiment of the present application illustrated in
In one form, each of the docking devices 110, 120 and 130 is configured to correspond to the specific needs of a user likely to use the respective docking device 110, 120 and 130. For example, in one form, one of the docking devices 110, 120 and 130 is configured to be used by an insulin dependent diabetic, a second of the docking devices 110, 120 and 130 is configured to be used by a physician, and a third of the docking devices 110, 120 and 130 is configured to be used by a dietician. Several exemplary differences between the functionality of the docking devices in this arrangement can be present. For example, the first one of the one of the docking devices 110, 120 and 130 can include a calendar, which provides reminders for checking bG levels or taking insulin, which is not included by the second and third docking devices. As another example, the second one of devices 110, 120 and 130 can be configured to provide sophisticated graphical analysis of bG measurement data useful to the physician, but not otherwise useful to the insulin-dependent diabetic or the dietician. To that end, the other two docking devices are not configured to provide this type of bG measurement data analysis. Still, further examples of differences between the docking devices 110, 120 and 130 are contemplated by the subject application. Additionally, it should be appreciated that devices 110, 120 and 130 can be configured for users beyond those described above.
While not specifically described above, it should be appreciated that bG meter 20 can be used to measure blood glucose values as a stand-alone device and/or when it is positioned in receptacle 64 of docking device 50. For example, when used alone, a user can control bG meter 20 with entry means 26, if necessary, and the information related to the functions performed by bG meter 20, including the results of blood glucose measurements, are provided on display 24. In the arrangement where bG meter 20 is positioned in receptacle 64 of docking device 50 however, a user can control bG meter 20 with entry means 68, if necessary, and the information related to the functions performed by bG meter 20, including the results of blood glucose measurements, are provided on display 70 of docking device 50. In one form of this arrangement, it is contemplated that the information on display 70 of docking device 50 is the same as or substantially similar to the information provided on display 24 of bG meter 20 when bG meter 20 is used alone. Moreover, the information may be provided on display 70 in a format that is the same as or substantially similar to the format in which the information is provided on display 24 of bG meter 20. Additionally, the manner for operating and controlling bG meter 20 with docking device 50 may be the same as or substantially similar to the manner in which bG meter 20 is operated and controlled when bG meter 20 is used alone. As an additional or alternative feature of the arrangement where bG meter is positioned in receptacle 64 of docking device 50, it is contemplated that the ability for a user to control bG meter 20 with entry means 68 of docking device 50 may generally occur automatically, or seamlessly, as a result of the communication interface between bG meter 20 and docking device 50. Similarly, the information related to the functions performed by bG meter 20, including the results of blood glucose measurements, may generally be provided automatically, or seamlessly, on display 70 of docking device 50 as a result of the communication interface between bG meter 20 and docking device 50. Further details regarding various configurations for displaying blood glucose measurements on one or both of bG meter 20 and docking device 50 are described in U.S. patent application Ser. No. ______, titled “Blood Glucose Management and Interface Systems and Methods” (Attorney Docket No. ROCD-12/WP24855US) and filed on the same date as the subject application, the disclosure of which is incorporated herein by reference in its entirety. However, it also contemplated that entry means 68 and display 70 of docking device 50 will not control bG meter 20 or provide information related to its functions unless first prompted by a user with, for example, entry means 68 of docking device 50.
