A person with diabetes may be alerted by a blood glucose monitoring device to current or future predicted out-of-normal-glucose-range events which may be imminently dangerous, such as hyperglycemia or hypoglycemia. During these out-of-normal-glucose-range events, the user may have such elevated mental confusion that that the user fails to realize the dangerous state is occurring and/or take action to treat their glucose state. A user's phone or continuous glucose monitor (CGM) controller device may be an external device to a user that may alert the user of the imminently dangerous event, but the user may not be near the phone or CGM controller device. Some systems may also contact an emergency service when the user is initially unresponsive to such alerts.
The user's lack of response, however, may not indicate that the user is in need of emergency assistance. It may be undesirable to contact an emergency service when user is capable of self-treatment. Communicating emergency alerts or contacting emergency services when a user is aware of their diabetic state and capable of self-treatment may waste communication resources (e.g., communicating to emergency contacts, communicating messages over a network unnecessarily, etc.) and processing resources on a device providing alerts.
Some insulin pumps are also now integrated with systems for automatically controlling the insulin levels in response to changes in blood glucose levels. For example, insulin pumps are integrated with CGMs and can shut off insulin delivery when blood glucose levels are dropping too quickly to help prevent hypoglycemia. If the user is aware of the diabetic event and capable of self-treatment, the resources on the insulin pump may also be preserved when the user implements another form of treatment.
A user may be alerted by one or more user devices (e.g., a mobile device, a CGM controller, a BGM, and/or another device) when the blood glucose level of the user is above a predefined threshold or below a predefined threshold that indicate the user has reached, or may imminently reach, an extreme diabetic state. The predefined threshold may be a high-end threshold that indicates that the user has reached, or may imminently reach, a hyperglycemic state. The predefined threshold may be a low-end threshold that indicates that the user has reached, or may imminently reach, a hypoglycemic state. When the predefined threshold for the blood glucose level of the user is reached, the user be in a state of elevated mental confusion and may be unable to realize the extreme state or take immediate action to self-treat the diabetic condition.
The user may be provided with a self-treat test that includes pass/fail criteria to test the ability of the user to perform self-treatment. The self-treat test may be provided by one or more user devices, such as the mobile device, the CGM controller, the BGM, and/or the insulin pump. The self-treat test may be initially performed by a user to set a baseline when the user's blood glucose is at a normal level. The same test that has been previously provided to the user to set the baseline may be provided to determine whether the user is capable of performing self-treatment when the user's blood glucose levels have increased or decreased.
The self-treat test may comprise a cognitive test, such as a concentration test, a math test, or a memory test. In the cognitive test, the pass/fail criteria may include at least one question to the user. The self-treat test may test the dexterity of the user. For example, the pass/fail criteria may comprise a relative change in acceleration or a relative change in orientation of the user's mobile device over a period of time, an ability of the user to trace a predefined shape on a display of a user device, and/or an ability of the user to identify a predefined sequence of shapes displayed on a screen to the user.
A timer may be set to give the user time to perform the self-treat test and/or treat the extreme diabetic state. The timer may be set differently based on different levels of severity for the extreme diabetic state. A longer timer may be triggered after detection of a lower level of severity associated with the extreme diabetic state than for higher levels of severity. The timer may allow a user time to treat the extreme diabetic state and/or provide information indicating that treatment has occurred. As different users may react differently to different blood glucose levels, the timer may be user-defined or defined by a third party (e.g., such as a physician) on the user device and stored in memory.
If the user passes the self-treat test, the user may be assumed to be able to treat the diabetic condition themselves. If the user fails the test, a diabetes-related alert may be provided via a user device. The diabetes-related alert may be an audible alert communicated via a speaker of the mobile device. The diabetes-related alert may be communicated otherwise, for example, to an external speaker device for audible communication to an occupant of a space, via telecommunication or text message, and/or via a home automation system.
The blood glucose monitoring device may be a continuous glucose monitor (CGM) 102. The CGM 102 may include a subcutaneous sensor that is used to sense and monitor the amount of glucose in interstitial fluid of the user 100. The CGM 102 may include a transmitting device that is located directly over the sensor that wirelessly powers the data transfer from the sensor. The CGM 102 may periodically communicate data indicating the blood glucose levels of the user 100 to an external device, such as a mobile device 104, for computing and/or storing the blood glucose levels of the user 100. The mobile device 104 may operate as a CGM controller device. Though the mobile device 104 may be provided as an example of a device with which the CGM 102 may communicate, the CGM 102 may communicate with other dedicated CGM controller devices for providing similar functionality that is described herein for the mobile device 104. The mobile device 104, or another CGM controller device, may provide audible alerts, graphical user interfaces, or non-audible alerts in response to data indications or triggers identified in the monitored blood glucose data. The CGM 102 may include an electric motor for providing on-body vibration alerts and/or a speaker for providing audible alerts in response to data indications or triggers identified in the monitored blood glucose data. The CGM 102 may process the blood glucose data for providing alerts, or the blood glucose data may be processed at the mobile device 104, or other CMG controller device, an alert indicator may be communicated to the CGM 102.
The blood glucose monitoring may be performed by flash glucose monitoring (FGM). The FGM may include a subcutaneous sensor 103 that is used to sense and monitor the amount of glucose in interstitial fluid of the user 100. A separate reader device, such as the mobile device 102 or another reader device, may receive the blood glucose information from the sensor when the device is within the RF range of the sensor 103. The sensor 103 may transmit an instantaneous blood glucose level and/or a graphical trend of the blood glucose level to the reader device for display.
The user 100 may use a blood glucose meter (BGM) 106 as a blood glucose monitoring device to monitor blood glucose levels. The BGM 106 may include port 108 that may receive a blood glucose measurement strip 110. The user 100 may deposit a sample of blood on the blood glucose measurement strip 110. The BGM 106 may analyze the sample and measure the blood glucose level in the sample. The blood glucose level measured from the sample may be displayed on a display 112 of the BGM 106 and/or communicated to an external device, such as the mobile device 104.
The blood glucose level measured by the BGM 106 and/or computed using data received from the CGM 102 may be used to treat the diabetic condition of the user 100. For example, the user 100 may use an ambulatory non-durable insulin pump 116 or an ambulatory durable insulin pump 118 to treat the diabetic condition with insulin. The mobile device 104 may determine an amount of insulin to be administered to the user 100 and the insulin pump 116, 118 may receive instructions from the mobile device 104 to deliver a predetermined amount of insulin to the user 100. The insulin pump 116, 118 may receive other information from the mobile device 104, such as mealtime information and/or exercise information of the user 100. The insulin pump 116, 118 may determine the amount of insulin to administer based on the received information from the mobile device 104. The insulin pump 116, 118 may communicate information to the mobile device 104. The information communicated to the mobile device 104 may include an amount of insulin delivered to the user 100, corresponding times of delivery, and/or a pump status (e.g., battery status, insulin status, etc.).
The mobile device 104 may communicate with the insulin pump 116, 118, the CGM 102, and/or the BGM 106 using wired and/or wireless communications. The mobile device 104, the CGM 102, a CGM controller, the BGM 106, and/or the insulin pump 116, 118 may be collectively referred to as user devices. The mobile device 104 may communicate with the other user devices using the same or different wireless protocols. For example, the mobile device 104 may communicate with the other user devices using BLUETOOTH®, near field communication (NFC), THREAD, WIFI®, ZIGBEE®, WI-MAX®, a cellular communication protocol, a proprietary wireless communication protocol, or another radio frequency (RF) communication protocol.
The mobile device 104 may be a mobile phone, a tablet, a laptop, a wearable device, a personal digital assistant (PDA), or another mobile computing device. If the mobile device 104 is a wearable device, the wearable device may be an armband (e.g., a smart watch, such as an APPLE® watch, a FITBIT® armband, or other device capable of being worn on the arm of the user 100), a ring, glasses (e.g., GOOGLE® GLASS™), a headset (e.g., BLUETOOTH® headset), clothing (e.g., shirts, gloves, etc.), or another wearable device capable of being worn by the user 100. Though a mobile device may be described herein, other computing devices may be similarly implemented to perform functions of the mobile device.
The mobile device 104 may receive data and store data for assisting in monitoring and/or treating the diabetic condition. The mobile device 104 may receive input from the user 104 via a user interface being provided on a display. The mobile device 104 may receive input via hard buttons or soft buttons provided on the display.
The mobile device 104 may be configured to determine the device's location. For example, the mobile device 104 may be able to determine the geolocation (e.g., latitude and longitude) of the device using signals from a global positioning system (GPS) or triangulation via cellular communications. The mobile device 104 may determine a relative location using an RF beacon device 126. The RF beacon device 126 may communicate a unique identifier via a short-range wireless communication, such as a BLUETOOTH® low energy (BLE) beacon or an NFC beacon. The mobile device 104 may receive the RF beacon and perform a lookup in a database (e.g., in information from the datastores 124) to determine a relative location associated with the unique identifier. For example, the mobile device 104 may determine that the RF beacon indicates that the device is in a particular room in a home or building, on a certain floor in a building, close to a predefined object, or is within the RF range of a beacon associated with another object or location.
The mobile device 104 may include one or more sensors for detecting a relative position of the device or information about the user 100. The mobile device 104 may detect a movement or a change in orientation. Based on the movement and/or change in orientation (or lack thereof) of the mobile device 104 over a period of time, the mobile device 104 may detect that the user 100 is standing, sitting, or lying down. The mobile device 104 may detect that the user 100 is exercising when the movement and/or the change in orientation is greater than a threshold for a period of time. The mobile device 104 may detect the heartrate of the user 100 using a heartrate sensor. Based on the heartrate and the movement of the user 100 over a period of time, the mobile device 104 may detect whether the user 100 is asleep or awake. The information about the mobile device 104 and/or the user 100 may be used to provide information about and/or treat the diabetic condition.
The mobile device 104 may provide information to the user 100 about the user's diabetic condition. For example, the mobile device 104 may provide blood glucose levels, provide meal-related information, provide exercise-related information, generate graphs and other graphical user interfaces for display, and/or generate alerts that may be provided to the user 100. For example, the mobile device 104 may measure the blood glucose level of the user 100 and provide an alert when the blood glucose level of the user 100 has reached a threshold for an extreme diabetic state (e.g., hypoglycemia or hyperglycemia). The alerts provided by the mobile device 104 may be audible and/or non-audible alerts. The non-audible alerts may be provided as a vibration, a flashing of the screen, or a flashing of an LED on the mobile device 104. The alerts may also, or alternatively, be provided by an external device based on a communication from the mobile device 104.
The mobile device 104 may communicate with other devices directly via a wired communication or a short-range wireless communication (e.g., WI-FI®, BLUETOOTH®, BLE, NFC, etc.). The mobile device 104 may communicate indirectly with remote computing devices 122 and/or datastores 124 via a network 120 (e.g., using a WI-FI® network, a cellular network, a WI-MAX® network, etc.). The network 120 may be a wired and/or wireless network. The network 120 may be used to communicate over the Internet to other devices.
The mobile device 104 may communicate with the remote computing devices 122 to generate user interfaces for display on the mobile device 104, perform remote computation, and/or otherwise control a remote computing device. For example, the mobile device 104 may provide a user interface via an application or web browser that is generated at a remote computing device 122. The mobile device 104 may generate instructions for providing alerts via remote computing devices 122 based on information received from the user 100, the CGM 102, the BGM 106, and/or the insulin pump 116, 118. Example remote computing devices 122 to which the mobile device 104 may send communications for performing alerts may include a remote computer (e.g., a server, a laptop, or other computer), an external speaker, an external display device (e.g., television, monitor, etc.), a home automation system, remote telecommunications devices (e.g., for sending text or voice communications to an emergency contact over a telecommunications network), or another remote computing device.
The mobile device 104 may communicate with the datastores 124 to store information and/or retrieve information. The information may include information related to the user 100, the CGM 102, the BGM 106, and/or the insulin pump 116, 118. For example, the mobile device 104 may receive treatment information associated with the user 100 as input or receive blood glucose information from the CGM 102 or the BGM 106 and send the information to the datastores 124 via the network 120. Stored information may be retrieved from the datastore 124 for treatment of the diabetic condition of the user. For example, the mobile device 104 may retrieve an amount of insulin delivered to the user 100 and/or corresponding times of delivery. The datastores 124 may include one or more remote storage locations, which may be collectively referred to as cloud storage.
As described herein, the user 100 may be alerted by one or more devices (e.g., the mobile device 104, the CGM 102, a CGM controller, the BGM 106, and/or another device) when the blood glucose level of the user 100 is above a predefined threshold or below a predefined threshold that indicate the user has reached, or may imminently reach, an extreme diabetic state. The predefined threshold may be a high-end threshold that indicates that the user 100 has reached, or may imminently reach, a hyperglycemic state. The predefined threshold may be a low-end threshold that indicates that the user 100 has reached, or may imminently reach, a hypoglycemic state. When the predefined threshold for the blood glucose level of the user 100 is reached, the user 100 may be in a state of elevated mental confusion and may be unable to realize the extreme state or take immediate action to self-treat the diabetic condition.
The user 100 may be provided with a self-treat test that includes pass/fail criteria to test the ability of the user 100 to treat themselves. The self-treat test may be provided by one or more user devices, such as the mobile device 104, the CGM 102, a CGM controller device, the BGM 106, and/or the insulin pump 116, 118. The self-treat test may be generated at a remote computing device 122 and/or information in the test may be retrieved from a datastore 124, and the test may be provided via one or more of the user devices. The self-treat test may be the same test that has been previously provided to the user 100 when the user 100 is determined to be in a state in which the user 100 is capable of self-treatment. For example, the self-treat test may be initially administered to the user 100 when the user 100 is determined to be in a normoglycemic state from the blood glucose level of the user 100 to generate a baseline from which a subsequent self-treat test may be compared.
The self-treat test may be implemented to users that may be symptomatic or asymptomatic. The self-treat test may assist symptomatic and/or asymptomatic users in detecting an extreme diabetic state earlier than may be otherwise detected. For example, an asymptomatic user may fail to detect the extreme diabetic state due to the user's failure to be alerted by symptoms that may be detectable by a symptomatic user. In a symptomatic user, the symptoms may be delayed or may fail to be detected by the user early enough to allow for proper treatment and/or assistance to be solicited.
As shown in
A baseline test may be provided to the user at 206 to test the baseline ability of the user to perform self-treatment of a diabetic condition when the user is in the normoglycemic state. The baseline test may be provided by the processor of the user device, such as the user's mobile device. For example, the baseline test may be provided during setup of an application on the user's mobile device. The baseline test may include predefined pass/fail criteria for testing the user's ability to treat the diabetic condition themselves.
The baseline test may be a cognitive test that may test the mental state of the user by testing the user's ability cognitive ability to infer the user's ability to perform self-treatment. For example, the test may be a memory test that tests the ability to retain and recall information. The pass/fail criteria for the memory test may include an ability to answer generally well-known trivia questions to test the recall of the user. The trivia test may ask the user “Who is the current president of the United States?”. The pass/fail criteria for the memory test may include an ability to recall an object that is flashed on the screen of the user device, such as a number, letter, or shape.
The test may be a concentration test that may test the mental state of the user by testing the user's ability to concentrate. The pass/fail criteria for the concentration test may include an ability to identify a predefined image of an object from a number of images of objects in a same category, such as an image of a hammer from a group of images of tools. The user device may access user-specific information and the predefined pass/fail criteria may be based on user-specific information from a user device. For example, the pass/fail criteria for a concentration test may include an ability to identify of an image of a known person from a group of images of people on the user's mobile device (e.g., in a photo album or contact list).
The test may be a math test that includes basic mathematical equations (e.g., basic addition, subtraction, multiplication, or division) to test the mental state of the user through testing the mathematical processing of the user. The pass/fail criteria for the math test may include an ability to correctly answer basic mathematical questions, such as “What is 27+36?”.
The test may be a test of manual dexterity. The dexterity test may test the mental and/or physical state of the user. The dexterity test may test the physical state of the user by measuring the physical dexterity that may be needed to properly physically handle and interact with diabetes tools and/or objects for treatment. The dexterity test may be tested by a relative change in acceleration or a relative change in orientation of the user device over a period of time while the user holds the device. For example, the user may be asked to perform an action with the mobile device (e.g., move up and down, or keep stationary in hand). The pass/fail criteria for the test of manual dexterity may include an ability of the user to trace a displayed shape on the screen of the device and stay within a predefined distance or an ability of the user to touch the location of a sequence of shapes displayed on the screen. The pass/fail criteria for the test of manual dexterity may include a relative change in acceleration or a relative change in orientation of the mobile device over a period of time.
The responses to the baseline test may be received at 208. The responses may be received via the processor of the user device on which the baseline test is provided. The responses may be stored, at 210, on memory of the user device or on remote storage. At 212, the baseline may be established based on the baseline responses. The user response to the baseline test may be stored to establish the baseline for which subsequent tests may be compared. The baseline may be established by comparing the baseline responses to predefined successful responses to the pass/fail criteria. The baseline may be established based on the accuracy of the user. For example, baseline responses may be compared to the predefined responses and the baseline may be set to the accuracy percentage of the user when taking the baseline test. In another example, the baseline may be established based on the successful responses themselves. For example, the baseline responses may be stored, and the baseline may be established as the correct and incorrect responses by the user.
As shown in
After the triggering event is detected, at 304, an alert may be provided on the user device to inform the user that the user's blood glucose level is above or below the predefined threshold. The alert may be an audible or non-audible alert. The alert may be provided as a notification on a display of the user device that is generated by the processor of the user device. The notification may overlay a lock screen, home screen, or screen of another application executing on the user device. The notification may inform the user that the user is in an extreme diabetic state, or is predicted to be imminently in an extreme diabetic state. The audible alert may be a sound generated by the processor of the user device and transmitted via a local or remote speaker.
After the triggering event is detected, a timer may be started by the processor of the user device. The processor of the user device may await a predefined period of time for input regarding a self-treatment action being taken. This input may be provided from the user confirming that the appropriate self-treatment action has been taken, or the input may be provided in a series of steps, or confirmations, from the user as self-treatment occurs. If positive input fails to be provided within the period of time, a self-treat test may be generated and displayed by the processor to test if the user is mentally fit to perform self-treatment. The predefined period of time for setting the timer for providing the self-treat test may depend on the severity of the glucose level of the user (e.g., a low glucose level of 50 mg/dL may cause the timer to be set to a relatively shorter period of time than a higher glucose level of 79 mg/dL). The timer may be set as a function of the blood-glucose level of the user, after the blood-glucose level of the user reaches a pre-defined high or pre-defined low for the initial triggering event.
At 306, a determination may be made by the processor of the user device as to whether baseline test results are available. The baseline test results may be the results of a baseline test previously performed by the user and stored locally on the user device or at a remote device. In another example, the baseline test results may be predetermined results that establish a baseline against which a user's responses may be compared. If the baseline test results are determined to be available, a self-treat test may be provided by a user device to the user at 312. The self-treat test may include the same, or a subset of, the pass/fail criteria that were included in the baseline test. The self-treat test may be provided to the user via one or more of the user devices.
If it is determined that the user performed the self-treat test at 314 by attempting to complete the one or more pass/fail criteria, a determination may be made by the processor of the user device, at 316, as to whether the user passed the test. The determination may be made by comparing results of the baseline test with the results of the self-treat test. The user may be determined to pass the test if the results of the self-treat test are within a predefined deviation of the baseline test. The predefined deviation may be a percentage or number of correct responses. The predefined deviation may be set to zero, such that the user passes the self-treat test when the successful responses on the self-treat test are the same as the successful responses on the baseline test. The predefined deviation may be a deviation in the user's answers to questions; a deviation in the user's ability to trace a displayed shape on the screen of the user device and stay within a predefined distance; a deviation in the response time for the user selecting the location of a sequence of shapes displayed on the screen; a deviation in the relative change in acceleration or a relative change in orientation of the mobile device while the user is holding the device over a period of time; and/or a deviation in another input received from the user on the user device.
If the user passes the self-treat test, additional tests may be performed to confirm the results of the prior test. For example, the user may perform a dexterity test by being asked via instructions on the user device to hold the user's mobile phone steady for a period of time. The user device's change in orientation or movement may be used to measure the shakiness of the user and infer the severity of the extreme diabetic state and/or the presumed positively-correlated level of mental clarity. Any other test may be performed to confirm the results of the prior test to ensure the user is capable of self-treatment. Though additional tests may be performed, a single test may be performed to expedite the user's ability to treat themselves or request assistance.
If the user fails the test at 316, or the user fails to perform the test at 314, the user may be informed of the extreme diabetic state and/or test failure at 318. For example, the user device may inform the user via a user interface on a display of the user device, audibly by a local speaker on the user device, or via a device external to the user device. The inability to pass the test, or perform the test, may be correlated to a lack of mental ability to self-treat from the extreme diabetic event. Assistance may be solicited for the user by communicating a diabetes-related alert at 320.
The self-treat test may be provided to as a measurement to test the mental and/or physical state of the user. Though pass/fail criteria are described, the test results may indicate a relative level of the user's mental or physical state across a spectrum. The relatively higher the state of confusion (e.g., by answering more questions incorrectly), or lower the physical ability of the user (e.g., by being unable to perform physical tests), the less likely or able is the user is to execute a self-treatment event or to execute it effectively (e.g., hypo state unawareness, inability to recall strategies, inability to calculate carbs or insulin amounts needed, inability to recall previous actions already executed, inability to recall or execute steps in the right order, etc.). For example, the user may pass four out of five questions to give an indication of the relative mental and/or physical state of the user. The threshold for identifying whether a user passes or fails the self-treat test may be modified (e.g., by the user, a doctor, etc.).
If the user fails the self-treat test, additional tests may be performed to confirm the results of the prior test. An additional test may be performed to prevent assistance from being solicited on behalf of the user, when the user is capable of self-treatment. Though additional tests may be performed, a single test may be performed to expedite the user's ability to receive assistance.
The diabetes-related alert may solicit assistance in the treatment of the extreme diabetic state. The diabetes-related alert may be an audible alert generated by the processor of the user device and communicated via a speaker of one or more user devices. The diabetes-related alert may be communicated via one or more remote computing devices external to the user devices. For example, the diabetes-related alert may be communicated via an external speaker device for audible communication to an occupant of a space. The processor of the user device or devices may send a message to the external speaker device via a communication circuit to cause the external speaker device to communicate a predefined message for the diabetes-related alert to occupants of a space. The processor of the user device or devices may send a predefined message via a communication circuit for the diabetes-related alert via a messaging system (e.g., instant messenger), email, telecommunication, social media, or text message to a remote device. The processor of the user device or devices may send a message via a communication circuit that is configured to control a home automation system to alert an occupant of a space. For example, the message may be configured to control the lights, blinds, or switching mechanisms for electrical outlets or light switches in the home automation system to alert the user (e.g., using an ambient display). One or more lights (e.g., a red lamp) in a space may be dedicated for alerting occupants of a space regarding the user's extreme diabetic state.
If the user passes the test at 316, a determination may be made at the processor of the user device that the user is capable of self-treating the extreme diabetic state. For example, if the user passes the test it may be assumed that the user has the cognitive ability to self-treat by properly treating the extreme diabetic state to bring the user's blood glucose level back to a normal level. The user may still be asked by the user device whether to solicit assistance. A determination may be made by the processor of the user device, at 308, as to whether the user assistance is requested. For example, a request may be displayed on a user interface of a user device. A determination may be made, based on the user input, to solicit assistance for the user at 320. If the user indicates the user does not want to solicit assistance at 308, or assistance has been solicited at 320, blood glucose information may continue to be monitored at 322 for subsequently providing self-treat tests and/or providing diabetes-related alerts.
If, at 306, the baseline test results are unavailable (e.g., the user has not previously performed the baseline test or the predefined baseline test results are unavailable), a determination may be made by the processor of the user device as to whether the user assistance is to be requested at 308. A determination may be made, based on the user input and/or the baseline test results being unavailable, to solicit assistance for the user at 320.
As shown in
Different thresholds may be defined that correspond to different levels of severity associated with the extreme diabetic state in memory. For example, a first level of severity for a hypoglycemic state may be defined as a measurable glucose concentration of less than 70 mg/dL (3.9 mmol/L). The first level of severity may be defined as a range from an upper limit of 70 mg/dL (3.9 mmol/L) to a lower limit of 54 mg/dL (3.0 mmol/L). A second level of severity for a hypoglycemic state may be defined as a measurable glucose concentration of less than 54 mg/dL (3.0 mmol/L). The second level of severity may be the threshold at which neuroglycopenic symptoms may begin to occur. As such, more immediate action may be taken to resolve the extreme diabetic state. The second level of severity may be a range from an upper limit of 54 mg/dL (3.0 mmol/L) to a lower limit of 42 mg/dL (2.33 mmol/L). In another example, the second level of severity may be a smaller range from an upper limit of 54 mg/dL (3.0 mmol/L) to a lower limit of 53 mg/dL (2.94 mmol/L). The lower limit for the second level of severity may also range anywhere between 53 mg/dL (2.94 mmol/L) and 42 mg/dL (2.33 mmol/L), as an example. In an example in which one of the first or second levels of severity is omitted, a single level of severity may cover a range of the first and second levels of severity described herein. For example, a single level of severity may range from an upper limit of 70 mg/dL (3.9 mmol/L) to a lower limit of 53 mg/dL (2.94 mmol/L), or from an upper limit of 70 mg/dL (3.9 mmol/L) to a lower limit of 42 mg/dL (2.33 mmol/L). Another level of severity, or a third level of severity, for a hypoglycemic state may be defined as a measurable glucose concentration of less than the prior level(s) of severity. The third level of severity may be the threshold at which an extreme diabetic state may alter the mental and/or physical condition of the user. For example, the third level of severity may be defined as less than 53 mg/dL (2.94 mmol/L), less than 42 mg/dL (2.33 mmol/L), or anywhere in between. The third severity level may have a bottom limit, such that it includes a range. For example, the third level of severity may be defined as being between 53 mg/dL (2.94 mmol/L) and 30 mg/dL (1.67 mmol/L), or 42 mg/dL (2.3 mmol/L) and 30 mg/dL (1.67 mmol/L). For the third level of severity, an alert for immediate assistance may be sent. Though example thresholds are provided for different levels of severity for the hypoglycemic state, other thresholds and/or number of levels of severity may be defined.
Different thresholds may similarly be defined for the hyperglycemic state. For example, a first level of severity for a hyperglycemic state may be defined as a measurable glucose concentration of greater than 200 mg/dL (11.1 mmol/L). A second level of severity for a hyperglycemic state may be defined as a measurable glucose concentration of greater than 350 mg/dL (19.4 mmol/L). The second level of severity may be the threshold at which neuroglycopenic symptoms may begin to occur. As such, more immediate action may be taken to resolve the extreme diabetic state. A third level of severity for a hyperglycemic state may be defined as a measurable glucose concentration of greater than 700 mg/dL (38.8 mmol/L). The third level of severity may be the threshold at which an extreme diabetic state may alter the mental and/or physical condition of the user. For the third level of severity, an alert for immediate assistance may be sent. Though example thresholds are provided for different levels of severity for the hyperglycemic state, other thresholds and/or number of levels of severity may be defined.
Though certain thresholds may be used as examples herein, these thresholds may be modified. Different thresholds may be prestored, user-defined, and/or defined by a third party (e.g., a physician) on the user device and stored in memory. For example, the prestored thresholds may be a factory preset stored in the memory of one or more user devices. The prestored thresholds may be modified. The processor of the user device may limit the low-end threshold from being moved below a predefined low-end limit for detecting a hypoglycemic state. The processor of the user device may limit the high-end threshold from being moved above a predefined high-end limit for detecting a hyperglycemic state. The thresholds may be set to the low-end limit and/or the high-end limit as the factory preset stored in memory.
The thresholds may be user-defined to be specific to different users or types of users. Different thresholds may be stored for different users or types of users based on a duration of diabetes, an age/life expectancy, comorbid conditions, known cardiovascular disease or advanced microvascular complications, hypoglycemia unawareness, and/or other individual user considerations. The thresholds may also be determined by a function, which may be different based on different users or types of users.
After a level 1 severity is detected by the processor of the user device, at 356, a determination may be made by the processor at 362 as to whether baseline test results are available in memory. Similarly, after a level 2 severity is detected, at 358, a determination may be made at 362 as to whether the baseline test results are available. The baseline test results for the level 1 severity and may be the same as or different than the baseline test results for the level 2 severity of the extreme diabetic state.
If the baseline test results are determined to be unavailable at 362 (e.g., the user has failed to previously perform the baseline test or the predefined baseline test results are unavailable), a determination may be made at 372 as to whether the user assistance is to be requested. A determination may be made based on the user input and/or the baseline test results being unavailable. For example, the processor of the user device may display a request to the user to ask if the user would like to request assistance. If the user assistance is to be requested, the user assistance may be solicited for the user at 376. The user assistance may be requested by the user device sending a request via a communication circuit to another device.
If the baseline test results are determined to be available in memory, a timer may be started by the processor of the user device at 364. The timer may correspond to the severity level detected for the extreme diabetic state. The timer may be the same or different for the severity level detected for the extreme diabetic state. A longer timer may be triggered after detection of a level 1 severity associated with the extreme diabetic state than for the level 2 severity. For example, a three-minute timer may be triggered after the level 1 severity is detected, while a one-minute timer may be triggered after the level 2 severity is detected. The timer may allow a user time to treat the extreme diabetic state and/or provide information indicating that the treatment has occurred. As different users may react differently to different blood glucose levels, the timer may be user-defined or defined by a third party (e.g., such as a physician) on the user device and stored in memory for different levels of severity. The timer may also, or alternatively, be set as a function of the severity level or blood glucose level of the user. For example, a longer timer may be set (e.g., established from an upper limit) for lower severity levels, while a shorter timer may be set (e.g., established from an upper limit) for higher severity levels.
At 366, a determination may be made by the processor of the user device as to whether an indication has been received that indicates the extreme diabetic state has been treated appropriately. For example, the user may provide information at the user's mobile device, or another computing device, by selecting a button and/or entering text indicating that an appropriate amount of carbohydrates have been consumed or an appropriate amount of glucagon has been administered to treat a hypoglycemic state. The user may also, or alternatively, press a button and/or provide text on the user's mobile device, or another computing device, indicating that an appropriate amount of insulin has been administered to treat a hyperglycemic event. The mobile device or other computing device may receive a message from another user device, such as an insulin pump, CGM, or a BGM, that an appropriate amount of insulin has been a administered or a user's blood-glucose levels have been treated.
Glucose (e.g., 15-20 g) may be a treatment for a conscious individual with a level 1 hypoglycemia. Level 1 hypoglycemia may be detected when the blood glucose level of the user is less than 70 mg/dL (3.9 mmol/L). Any form of carbohydrate that includes glucose may be used for treatment. After a period of time has elapsed (e.g., fifteen minutes) after treatment, if updated blood glucose information shows continued hypoglycemia, the treatment may be repeated. Once the updated blood glucose information indicates that the blood glucose level of the user returns to normal, the user may consume additional glucose to prevent recurrence of hypoglycemia. Glucagon may be prescribed to users at increased risk of level 2 hypoglycemia. Level 2 hypoglycemia may occur when the blood glucose level of the user is less than 54 mg/dL (3.0 mmol/L).
After a user has been treated, hypoglycemia unawareness or one or more episodes of level 3 hypoglycemia may trigger reevaluation of the treatment regimen. Insulin-treated users with hypoglycemia unawareness or an episode of level 2 hypoglycemia may be advised via the display of the user device to raise their glycemic targets to strictly avoid hypoglycemia for at least several weeks in order to partially reverse hypoglycemia unawareness and reduce risk of future episodes.
If an indication is received at 366 indicating that the extreme diabetic state has been treated, a determination may be made by the processor of the user device at 372 as to whether the user assistance is to be requested. A determination may be made based on the user input in response to a request displayed on the user device and/or the indication of the extreme diabetic state being indicated as being treated at 366. If the user assistance is to be requested, the user assistance may be solicited for the user at 376.
The processor of the user device may continue to monitor the expiration of the timer at 368 and if the indication of the extreme diabetic state being treated fails to be received after the expiration of the timer, the processor of the user device may provide a self-treat test to the user at 370. The self-treat test may be displayed on a display of the user device, such as the display of the user's mobile device for example. The self-treat test for a level 1 severity may be the same or different than the self-treat test for a level 2 severity associated with the extreme diabetic state.
At 371, a determination may be made by the processor of the user device as to whether the user passed the self-treat test. At 371, the determination may include determining whether the user attempted one or more pass/fail criteria of the self-treat test. The determination as to whether the user passed the test may be made by comparing results of the baseline test with the results of the self-treat test. The user may be determined to pass the test if the results of the self-treat test are within a predefined deviation of the baseline test. The predefined deviation may be a percentage or number of correct responses. The predefined deviation may be set to zero, such that the user passes the self-treat test when the successful responses on the self-treat test are the same as the successful responses on the baseline test. The predefined deviation may be a deviation in the user's answers to questions; a deviation in the user's ability to trace a displayed shape on the screen of the user device and stay within a predefined distance; a deviation in the response time for the user selecting the location of a sequence of shapes displayed on the screen; a deviation in the relative change in acceleration or a relative change in orientation of the mobile device while the user is holding the device over a period of time; and/or a deviation in another input received from the user on the user device.
If the user passed the self-treat test, additional tests may be performed to confirm the results of the prior test. Though additional tests may be performed, a single test may be performed to expedite the user's ability to treat themselves or request assistance.
The determination at 371 may include determining whether the user passed the self-treat test within a period of time. A test timer may be started by the processor of the user device when the self-treat test is provided to the user. The test timer may be different for different levels of severity and/or blood glucose levels of the user. The test timer may be shorter than the timer at 364, which may be referred to as a self-treat timer. Though the timer at 364 may be set for the amount of time for self-treatment by the user and/or passing of the self-treat test. The test timer may be set to a time limit that is less than the self-treat timer, as the severity of the user's condition may have increased. The test timer may be set as a function of the self-treat timer and/or the severity level. For example, the self-treat timer may be a multiple or an order of magnitude greater that the test timer. The multiple or magnitude may be increased as the severity level of the extreme diabetic state (e.g., detected at 356, 358) is decreased. When the extreme diabetic state of the user is detected as being a level 1 severity, the self-treat timer may be set to three minutes and the test timer may be set to twenty seconds, for example. In another example, when the extreme diabetic state of the user is detected as being a level 2 severity, the self-treat timer may be set to one minute and the test timer may be set to ten seconds.
If the user fails the test or fails to perform the test at 371 (e.g., within a period of time), the user may be informed of the extreme diabetic state and/or test failure at 374. For example, the processor of the user device may inform the user via a user interface on a display of the user device, audibly by a speaker, or via a device external to the user device. The inability to pass the test, or perform the test, may be correlated to a lack of mental ability to self-treat from the extreme diabetic event. Assistance may be solicited for the user by communicating a diabetes-related alert at 376.
The diabetes-related alert may solicit assistance in the treatment of the extreme diabetic state. The diabetes-related alert may be an audible alert generated by the processor of the user device and communicated via a speaker of one or more user devices. The diabetes-related alert may be communicated via one or more remote computing devices external to the user devices. For example, the diabetes-related alert may be communicated via an external speaker device for audible communication to an occupant of a space. The processor of the user device or devices may send a message to the external speaker device via a communication circuit to cause the external speaker device to communicate a predefined message for the diabetes-related alert to occupants of a space. The processor of the user device or devices may send a predefined message via a communication circuit for the diabetes-related alert via a messaging system (e.g., instant messenger), email, telecommunication, social media, or text message to a remote device. The processor of the user device or devices may send a message via a communication circuit that is configured to control a home automation system to alert an occupant of a space. For example, the message may be configured to control the lights, blinds, or switching mechanisms for electrical outlets or light switches in the home automation system to alert the user (e.g., using an ambient display). One or more lights (e.g., a red lamp) in a space may be dedicated for alerting occupants of a space regarding the user's extreme diabetic state.
If the user passes the test at 371, a determination may be made on the processor of the user device that the user is capable of self-treating the extreme diabetic state. For example, if the user passes the test it may be assumed by the user device that the user has the cognitive ability to self-treat by properly treating the extreme diabetic state to bring the user's blood glucose level back to a normal level. The user may still be asked by text on the display or speaker of the user device whether to solicit assistance. A determination may be made by the processor of the user device, at 372, as to whether the user assistance is requested. For example, a request may be displayed by the processor on a user interface of the user device. A determination may be made, based on the user input, to solicit assistance for the user at 372. If the user indicates the user does not want to solicit assistance at 372, or assistance has been solicited at 376, blood glucose information may continue to be monitored at 378, 380 for subsequently providing self-treat tests and/or providing diabetes-related alerts.
Referring back to 354 of the method 300, the detected triggering event associated with the extreme diabetic state may have a higher level of severity. For example, the processor of the user device may detect a level 3 severity at 360. The third level of severity may be the threshold at which an extreme diabetic state may alter the mental and/or physical condition of the user. For the third level of severity, an alert for immediate assistance may be sent. For example, when level 3 severity, or another severity level defined as being similarly extreme, is detected, the processor of the user device may skip any processing or time allocating for enabling self-treatment and/or performance of the self-treat test by the user. The processor of the user device may proceed to solicit assistance of the user at 376. This assistance may be solicited immediately, as the user may be automatically detected as being incapable of self-treatment and/or passing the self-treat test.
The GUI 402 may include an alert 404. The alert 404 may indicate the user's blood glucose level, an indication of a current or predicted extreme diabetic state, and/or an indication to consume carbs or insulin to help self-treat the extreme diabetic state. The alert 404 may request the user to perform a test to indicate the user's ability to perform self-treatment.
The GUI 402 may include a self-treat test 406. The self-treat test may be provided with the alert 404, or after selection (e.g., of a button) by a user to indicate the user would like to take the test. The self-treat test 406 may include one or more pass/fail criteria. The number of pass/fail criteria (e.g., questions, etc.) that are displayed to the user on the user device may depend on the type of user device. For example, a tablet or mobile device may have a larger display than a CGM or CGM controller to allow more questions to be displayed to the user. The number of criteria may be automatically determined based on the display size of the user device.
The GUI 402 may include an exit button 408 that may allow the user to exit the test. If the user exits, or does not perform the test over a predefined period of time, a diabetes-related alert may be communicated from the user device 400 to solicit assistance for the user. It may be assumed that the user is incapable of passing the self-treat test 406. The exit button 408 may be inoperable until after the user attempts the self-treat test 406.
As shown in
The GUI 402 may include an additional test 412 to confirm that the user has the ability to perform self-treatment. For example, the GUI 402 may ask the user to perform a dexterity test by asking the user to hold the user device steady for a period of time. The user device 400 may monitor relative changes in orientation or movement in a direction and determine that the user has passed or failed the test based on whether the orientation or movement is within a predefined threshold for a period of time. The user device's change in orientation or movement may be used to measure the shakiness of the user and infer the severity of the extreme diabetic state and/or the presumed positively-correlated level of mental clarity. Any other test may be performed to confirm the results of the prior test to ensure the user is capable of self-treatment. Though additional tests may be performed, a single test may be performed to expedite the user's ability to self-treat or request assistance.
As shown in
The GUI 402 may include an additional test (not shown) prior to communicating the diabetes related alert to solicit assistance on behalf of the user. An additional test may be performed to prevent assistance from being solicited on behalf of the user, when the user is capable of self-treatment. Though additional tests may be performed, a single test may be performed to expedite the user's ability to receive assistance.
As shown in
The GUI 402 may allow the user to enable/disable the self-treat test based on an actuation of the setting 424. The user device may prevent the user from disabling the self-treat test. An identifier and/or password 426 may be entered to disable the self-treat test. The identifier and/or password may be associated with another user, such as a healthcare provider, for example. This may prevent a user that is in an extreme diabetic state from unknowingly disabling the self-treat test and/or emergency alerts associated therewith.

The processor 802 may be in electrical communication with a memory 816. The processor may store information in and/or retrieve information from the memory 816. The memory 816 may include a non-removable memory and/or a removable memory for storing computer-readable media. The non-removable memory may include random-access memory (RAM), read-only memory (ROM), a hard disk, and/or any other type of non-removable memory storage. The removable memory may include a subscriber identity module (SIM) card, a memory stick, a memory card (e.g., a digital camera memory card), and/or any other type of removable memory. The processor 802 may access the memory 816 for executable instructions and/or other information that may be used by the insulin pump 800.
The insulin pump 800 may include a communication circuit 818. The processor 802 may be in electrical communication with the communication circuit 818 for sending and/or receiving information. The communication circuit 818 may be capable of performing wired and/or wireless communications. For example, the wireless communications circuit 818 may include a radio frequency (RF) transceiver for transmitting and receiving RF signals (e.g., BLUETOOTH®, near field communication (NFC), WIFI®, WI-MAX®, cellular, etc.) via an antenna, or other communications module capable of performing wireless communications. The communication circuit 818 may be capable of performing infrared (IR) communications.
The processor 802 may be in electrical communication with a keypad 824 for providing input to the processor 802. The keypad 824 may include one or more keys for receiving input from a user. The keypad 824 may include hard or soft keys for which the function of the keys may change as a user performs selections.
Other input into the processor 802 be provided by sensors 826. The sensor 826 may include a pressure sensor that is sensitive to the pressure within a reservoir of insulin; a cartridge sensor that is sensitive to the presence of an insulin cartridge and/or a motion sensor that detects the motion of a gear (not shown) in the drive unit 812.
