Description
- The present application is a continuation of U.S. patent application Ser. No. 13/858,562 filed Apr. 8, 2013, now U.S. Pat. No. 8,676,601, which is a continuation of U.S. patent application Ser. No. 13/400,026 filed Feb. 17, 2012, now U.S. Pat. No. 8,417,545, which is a continuation of U.S. patent application Ser. No. 12/031,664 filed Feb. 14, 2008, now U.S. Pat. No. 8,121,857, which claims priority under §35 U.S.C. 119(e) to U.S. provisional patent application No. 60/890,154 filed Feb. 15, 2007, entitled “Device And Method For Automatic Data Acquisition And/Or Detection”, the disclosures of each of which are incorporated herein by reference for all purposes.
- In diabetes management, there exist devices which allow diabetic patients to measure the blood glucose levels. One such device is a hand-held electronic meter such as blood glucose meters such as Freestyle® blood glucose monitoring system available from Abbott Diabetes Care Inc., of Alameda, Calif. which receives blood samples via enzyme-based test strips. Typically, the patient lances a finger or alternate body site to obtain a blood sample, applies the drawn blood sample to the test strip, and the strip is inserted into a test strip opening or port in the meter housing. The blood glucose meter converts a current generated by the enzymatic reaction in the test strip to a corresponding blood glucose value which is displayed or otherwise provided to the patient to show the level of glucose at the time of testing.
- Such periodic discrete glucose testing helps diabetic patients to take any necessary corrective actions to better manage diabetic conditions. Presently available glucose meters have limited functionalities (for example, providing the glucose value measured using the test strip and storing the data for subsequent recall or display) and do not provide any additional information or capability to assist patients in managing diabetes.
- In accordance with the various embodiments of the present disclosure, there are provided methods and devices for detecting a predefined parameter associated with an operational condition of an analyte monitoring device, transmitting a request for time information in response to the predefined parameter detection, and receiving time information in response to the transmitted request.
- These and other objects, features and advantages of the present disclosure will become more fully apparent from the following detailed description of the embodiments, the appended claims and the accompanying drawings.

-
FIG. 1 is a block diagram illustrating a therapy management system for practicing one embodiment of the present disclosure. Referring toFIG. 1 , thetherapy management system 100 includes ananalyte monitoring system 110 operatively coupled to afluid delivery device 120, which may be in turn, operatively coupled to aremote terminal 140. As shown in the Figure, theanalyte monitoring system 110 is, in one embodiment, coupled to thepatient 130 so as to monitor or measure the analyte levels of the patient. Moreover, thefluid delivery device 120 is coupled to the patient using, for example, an infusion set and tubing connected to a cannula (not shown) that is placed transcutaneously through the skin of the patient so as to infuse medication such as, for example, insulin, to the patient. - Referring to
FIG. 1 , theanalyte monitoring system 110 in one embodiment may include one or more analyte sensors subcutaneously positioned such that at least a portion of the analyte sensors are maintained in fluid contact with the patient's analytes. The analyte sensors may include, but are not limited to short term subcutaneous analyte sensors or transdermal analyte sensors, for example, which are configured to detect analyte levels of a patient over a predetermined time period, and after which, a replacement of the sensors is necessary. - The one or more analyte sensors of the
analyte monitoring system 110 is coupled to a respective one or more of a data transmitter unit which is configured to receive one or more signals from the respective analyte sensors corresponding to the detected analyte levels of the patient, and to transmit the information corresponding to the detected analyte levels to a receiver device, and/orfluid delivery device 120. That is, over a communication link, the transmitter units may be configured to transmit data associated with the detected analyte levels periodically, and/or intermittently and repeatedly to one or more other devices such as thefluid delivery device 120 and/or theremote terminal 140 for further data processing and analysis. - In one aspect, each of the one or more receiver devices of the
analyte monitoring system 110 and thefluid delivery device 120 includes a user interface unit which may include a display unit, an audio output unit such as, for example, a speaker, or any other suitable user interface mechanism for displaying or informing the user of such devices. - The transmitter units of the
analyte monitoring system 110 may in one embodiment be configured to transmit the analyte related data substantially in real time to thefluid delivery device 120 and/or theremote terminal 140 after receiving it from the corresponding analyte sensors such that the analyte level such as glucose level of thepatient 130 may be monitored in real time. In one aspect, the analyte levels of the patient may be obtained using one or more of discrete blood glucose testing devices such as blood glucose meters that employ glucose test strips, or continuous analyte monitoring systems such as continuous glucose monitoring systems. In a further embodiment, theanalyte monitoring system 110 may include a blood glucose meter such as FreeStyle® and Precision meters available from Abbott Diabetes Care Inc., of Alameda Calif. The blood glucose meter may be used to calibrate the sensors in theanalyte monitoring system 110. Exemplary analyte systems that may be employed are described in, for example, U.S. Pat. Nos. 6,134,461, 6,175,752, 6,121,611, 6,560,471, 6,746,582, and elsewhere, the disclosures of which are herein incorporated by reference. - Analytes that may be monitored, determined or detected in the
analyte monitoring system 110 include, for example, acetyl choline, amylase, amyln, bilirubin, cholesterol, chorionic gonadotropin, creatine kinase (e.g., CK-MB), creatine, DNA, fructosamine, glucose, glutamine, growth hormones, hormones, ketones, lactate, measures for oxidative stress (such as 8-iso PGF2gamma), peroxide, prostate-specific antigen, prothrombin, RNA, thyroid stimulating hormone, and troponin. The concentration of drugs, such as, for example, antibiotics (e.g., gentamicin, vancomycin, and the like), biguanides, digitoxin, digoxin, drugs of abuse, GLP-1, insulin, PPAR agonists, sulfonylureas, theophylline, thiazolidinediones, and warfarin, may also be determined. - Moreover, within the scope of the present disclosure, the transmitter units of the
analyte monitoring system 110 may be configured to directly communicate with one or more of theremote terminal 140 or thefluid delivery device 120. Furthermore, within the scope of the present disclosure, additional devices may be provided for communication in theanalyte monitoring system 110 including additional receiver/data processing units, remote terminals (such as a physician's terminal and/or a bedside terminal in a hospital environment, for example). - In addition, within the scope of the present disclosure, one or more of the
analyte monitoring system 110, thefluid delivery device 120 and theremote terminal 140 may be configured to communicate over a wireless data communication link such as, but not limited to radio frequency (RF) communication link, Bluetooth® communication link, infrared communication link, or any other type of suitable wireless communication connection between two or more electronic devices, which may further be uni-directional or bi-directional communication between the two or more devices. Alternatively, the data communication link may include wired cable connections such as, for example, but not limited to RS232 connection, USB connection, or serial cable connection. - The
fluid delivery device 120 may include in one embodiment, but not limited to, an external infusion device such as an external insulin infusion pump, an implantable pump, a pen-type insulin injector device, a patch pump, an inhalable infusion device for nasal insulin delivery, or any other type of suitable delivery system. In addition, theremote terminal 140 in one embodiment may include for example, a desktop computer terminal, a data communication enabled kiosk, a laptop computer, a handheld computing device such as a personal digital assistant (PDAs), or a data communication enabled mobile telephone. - Referring back to
FIG. 1 , in one embodiment, theanalyte monitoring system 110 includes a strip port configured to receive a test strip for capillary blood glucose testing. In one aspect, the glucose level measured using the test strip may in addition, be configured to provide periodic calibration of the analyte sensors of theanalyte monitoring system 110 to assure and improve the accuracy of the analyte levels detected by the analyte sensors. - Referring yet again to
FIG. 1 , in one embodiment of the present disclosure, thefluid delivery device 120 may be configured to include a voice signal activation/generation unit for voice communication with theremote terminal 140 configured as a voice device such as a mobile telephone, a voice enabled personal digital assistant, a Blackberry device, or the like. For example, in one embodiment, the communication between thefluid delivery device 120 and theremote terminal 140 may be voice based such that the information or data output to the user from thefluid delivery device 120 is configured to be transmitted to the user's telephone. In turn, thefluid delivery device 120 may additionally be configured to receive voice commands from theremote terminal 140 configured as a telephone or any other voice signal communication device (such as personal computers or PDAs with voice signal capabilities). - In this manner, in one embodiment, the user interface of the
fluid delivery device 120 may be configured with the voice signal activation/generation unit such that, output information for the user is converted into a voice signal and transmitted to the voice signal enabledremote terminal 140. For example, when thefluid delivery device 120 detects an alarm condition, thefluid delivery device 120 is configured to initiate a telephone call to the user's telephone (remote terminal 140), and when the user picks up the telephone line, the user is provided with a voice signal representing the alarm condition. - In a further embodiment, for certain predetermined patient conditions, the
fluid delivery device 120 may be configured to initiate a telephone call directly to a preprogrammed telephone number of a health care physician, a local hospital, or emergency medical care facilities, in addition to or instead of initiating a telephone call to the user of thefluid delivery device 120. - In addition, within the scope of the present disclosure, interaction and programming of the
fluid delivery device 120 may be exclusively or partially exclusively performed over the user's telephone in voice communication with thefluid delivery device 120. That is, when the user wishes to calculate a carbohydrate bolus in thefluid delivery device 120, the user may dial a predetermined number using the user's telephone (remote terminal 140) to connect with thefluid delivery device 120, and the user may provide voice commands to thefluid delivery device 120 via the telephone connection between the user's telephone (remote terminal 140) and thefluid delivery device 120. -
FIG. 2 is a block diagram of a fluid delivery device ofFIG. 1 in one embodiment of the present disclosure. Referring toFIG. 2 , thefluid delivery device 120 in one embodiment includes aprocessor 210 operatively coupled to amemory unit 240, aninput unit 220, adisplay unit 230, anoutput unit 260, and a fluid delivery unit 250. In one embodiment, theprocessor 210 includes a microprocessor that is configured to and capable of controlling the functions of thefluid delivery device 120 by controlling and/or accessing each of the various components of thefluid delivery device 120. In one embodiment, multiple processors may be provided as safety measure and to provide redundancy in case of a single processor failure. Moreover, processing capabilities may be shared between multiple processor units within thefluid delivery device 120 such that pump functions and/or control may be performed faster and more accurately. - Referring back to
FIG. 2 , theinput unit 220 operatively coupled to theprocessor 210 may include a jog dial key pad buttons, a touch pad screen, or any other suitable input mechanism for providing input commands to thefluid delivery device 120. More specifically, in case of a jog dial input device, or a touch pad screen, for example, the patient or user of thefluid delivery device 120 will manipulate the respective jog dial or touch pad in conjunction with thedisplay unit 230 which performs as both a data input and output unit. Thedisplay unit 230 may include a touch sensitive screen, an LCD screen, or any other types of suitable display unit for thefluid delivery device 120 that is configured to display alphanumeric data as well as pictorial information such as icons associated with one or more predefined states of thefluid delivery device 120, or graphical representation of data such as trend charts and graphs associated with the insulin infusion rates, trend data of monitored glucose levels over a period of time, or textual notification to the patients. - In one embodiment, the alphanumeric representation displayed on the
display unit 230 may be configured to be modified by the user of the fluid delivery device such that the size of the displayed number or character may be adjusted to suit the user's visual needs. For example, in one embodiment, the user may apply font size adjustment request via theinput unit 220 to instruct theprocessor 210 to modify the size of the displayed number or character on thedisplay unit 230. In one aspect, the font size may be increased or decreased for each character, value or word displayed on thedisplay unit 230. Alternatively, the font size adjustment may be applied globally to all output settings, for example, under the control of theprocessor 210 such that the user setting of the size adjustment may be configured to apply to substantially all displayed values or characters on thedisplay unit 230 of the fluid delivery device 120 (FIG. 1 ). - Moreover, referring back to
FIG. 2 , in a further aspect of the present disclosure, the relative size adjustment of the displayed character or value may be determined by theprocessor 210 so that the relative size adjustment may be implemented to the output display on thedisplay unit 230. In this manner, depending upon the type or configuration of the display unit 230 (whether bit map or icon type display), in one embodiment, the display size adjustment may be implemented within the predetermined size restrictions for the respective value or character. For example, a 10% relative increase in the font size for display area designated for insulin dosage level may correspond to a 5% relative increase in the size of the display area designated for the insulin delivery time display. In one embodiment, theprocessor 210 may be configured to determine the relative size modification for each area of thedisplay unit 230 based on the user inputted size adjustment values to appropriately apply the relative size differential adjustment. - In a further aspect, the
processor 210 may be configured to temporarily increase the font size displayed on thedisplay unit 230 based on the user input commands such that the user requested size modification on thedisplay unit 230 may be implemented only for the displayed screen at the time the user input commands for size adjustment is received by theprocessor 210. In this manner, the processor may be configured to revert to the previously programmed display size settings for thedisplay unit 230 when the user is no longer viewing the particular displayed screen from which the user has requested font size adjustment. - In addition, the user interface of the receiver unit of the analyte monitoring system 110 (
FIG. 1 ) may be configured with similar size adjustment capabilities so as to allow the user to instruct the controller or processor of theanalyte monitoring system 110 to appropriately adjust the size of the displayed character or value on the display unit of theanalyte monitoring system 110. - In a further embodiment, the
display unit 230 may be configured to display an indication or marker for the type of insulin or other medication being used by thefluid delivery device 120 such as, for example, Symlin and Byetta. Such a marker may, in one embodiment, be associated with a predefined icon or character for display on thedisplay unit 230. In addition, within the scope of the present disclosure, the information associated with the displayed marker or indication may be stored in thememory unit 240 so that the user may retrieve this information as desired. In addition, an indication or a marker for shift work may be programmed in the fluid delivery device 120 (FIG. 1 ) such that shift workers using thefluid delivery device 120 may align days and nights upon command based on the markers. - For example, if a user worked nightshifts on Mondays and Tuesdays and dayshifts on Thursdays and Fridays, this daily work pattern information may be stored, identified or marked in the
fluid delivery device 120 to provide additional data management functionalities and a more robust therapy analysis. For example, meal times such as breakfasts, for example, at 8 pm on Monday and 9 pm on Tuesday (during the nightshifts) may be aligned with the breakfasts at 7 am on Thursday and 8 am on Friday. In this manner, the user may conveniently access meal (e.g., breakfast) related data and associated therapy information in conjunction with the operation of thefluid delivery device 120. This may assist the user in improving upon the user's diet such as the daily food intake. - Referring to
FIG. 2 , theoutput unit 260 operatively coupled to theprocessor 210 may include an audible alarm or alarms including one or more tones and/or preprogrammed or programmable tunes or audio clips, or vibratory alert features having one or more preprogrammed or programmable vibratory alert levels. - In addition, in one embodiment of the present disclosure, each alert event or alarm event may be programmed with combined notification features such that, depending upon the level of importance associated with each alert or alarm, a combination of vibratory, audible, or displayed indications may be provided to the user using the
display unit 230 in combination with theoutput unit 260. - For example, the
processor 210 may be configured to provide combined vibratory and increasingly audible alerts on theoutput unit 260 in addition to intermittently flashing background light on thedisplay unit 230 for one or more predetermined alarms that require immediate user attention. An example may include unexpected pressure increase in the infusion tubing which may indicate an occlusion or other undesirable condition that the user should be immediately notified. Theprocessor 210 may be configured such that the alarm or alert may be automatically reasserted within a predetermined time period in the event the associated alarm or alert condition has not been cleared by the user. In addition, each alert/alarm feature may be individually programmed to include a wide selection of tones, audible levels, vibratory strength, and intensity of visual display. - In a further aspect, the
fluid delivery device 120 may be configured to provide an alarm or alert indication associated with a change in temperature. That is, when thefluid delivery device 120 which contains the insulin (for example, in a reservoir) experiences a rise or drop in temperature, such change in the temperature may have an adverse effect on the insulin contained within thedevice 120. Accordingly, a temperature sensor may be coupled to theprocessor 210 of thefluid delivery device 120 to detect the operating condition of thefluid delivery device 120 and to notify the user of changes in the temperature, when, for example, the temperature change reaches a predetermined threshold level that may potentially have an adverse impact upon the efficacy of the insulin being delivered. - Also shown in
FIG. 2 is the fluid delivery unit 250 which is operatively coupled to theprocessor 210 and configured to deliver the insulin doses or amounts to the patient from the insulin reservoir or any other types of suitable containment for insulin to be delivered (not shown) in thefluid delivery device 120 via an infusion set coupled to a subcutaneously positioned cannula under the skin of the patient. - Referring yet again to
FIG. 2 , thememory unit 240 may include one or more of a random access memory (RAM), read only memory (ROM), or any other type of data storage unit that is configured to store data as well as program instructions for access by theprocessor 210 and execution to control thefluid delivery device 120 and/or to perform data processing based on data received from theanalyte monitoring system 110, theremote terminal 140, thepatient 130 or any other data input source. -
FIG. 3 is a flowchart illustrating the time zone detection procedure in the therapy management system in one embodiment of the present disclosure. Referring toFIG. 3 , the fluid delivery device 120 (FIG. 1 ) may be configured to transmit a location position request (310) to for example, a global positioning system (GPS). Thereafter, the location information is received (320) by theprocessor 210 of thefluid delivery device 120. Theprocessor 210 is further configured to determine whether the location information has changed (330). That is, theprocessor 210 in one embodiment is configured to compare the receive location information which may include a current time zone information associated with the location of thefluid delivery device 120, with the previously stored and operating time zone information in thefluid delivery device 120 in operation. - Referring back, if it is determined that the location information has not changed, then the routine terminates. On the other hand, if it is determined that the fluid delivery device location information has changed, then, the location change information is output (340) to the user on the
display unit 230, for example. Thereafter, theprocessor 210 may be configured to generate a user prompt or notification to modify the time zone information (350) of thefluid delivery device 120 such that it is updated to the new location where thefluid delivery device 120 is operating. - For example, when the
fluid delivery device 120 is programmed with predetermined basal profiles and/or bolus functions that are time based and associated with an internal clock of thefluid delivery device 120, it may be desired to modify some or all of the time based insulin delivery profiles programmed in thefluid delivery device 120 so as to correspond to the location of thefluid delivery device 120. More specifically, if a user is traveling from a first location to a second location in which one or more time zones are traversed, e.g., by way of example from San Francisco to Paris, given the time difference, the meal times, and sleep times, for example, will change. In this case, it may be desirable to modify the preprogrammed time based insulin delivery profiles so that they are synchronized with the user events such as meals and sleep times. - Referring back to
FIG. 3 , in one embodiment, the user responds to the time based programming change prompt provided by theprocessor 210, then theprocessor 210 may be configured in one embodiment, to propagate the time change associated with the preprogrammed insulin delivery profile and notify the user to confirm the changes, prior to implementing the modification to the delivery profiles and any associated alerts or notifications.
