[0002] This application claims priority from European application number 19305725.4 filed on June 5, 2019, the entire contents of which are incorporated herein by reference. Technical Field
[0003] The present invention relates to a medical device and method for administering basal and bolus insulin doses. Background Art
[0004] Diabetic patients lack insulin or cannot produce enough insulin to overcome potential insulin resistance or normalize glucose metabolism. Basal insulin or glargine insulin treatment is often used to achieve improved blood sugar control. Although blood sugar levels fluctuate throughout the day, "perfect blood sugar control" will mean that glucose levels are always within the range of 70 to 130 mg / dl or 3.9 to 7.2 mmol / L and cannot be distinguished from people without diabetes. Basal insulin or glargine insulin therapy can be used in combination with bolus insulin doses to achieve improved blood sugar control or as close to "perfect blood sugar control" as possible. In this therapy, basal insulin is provided throughout the day, which is supplemented with bolus insulin doses (e.g., based on the characterization of meals). However, it is more complicated to find the correct bolus dose for meals. The accurate bolus dose depends on the carbohydrate "carb" count, the ratio of insulin to carbohydrates, and the glucose correction factor. Due to these difficulties in determining the accurate bolus insulin dose, patients are unlikely to adopt mealtime bolus doses.
[0005] In addition, the complexity and difficulty of programming the bolus dose in some conventional insulin pumps further reduces the possibility that the patient adopts the mealtime bolus in its treatment. For example, for some conventional insulin pumps, programming the pump to deliver the bolus insulin dose needs to start from zero to the required bolus insulin dose. In some conventional insulin pumps, programming the insulin pump used in the basal insulin therapy to administer the bolus insulin dose requires multi-step programming and / or is relatively time-consuming. In addition, manually programming the pump to administer the bolus insulin dose may cause unexpected dosage errors. For example, the wrong dose may be entered. Summary of the invention
[0006] Some exemplary embodiments of the present disclosure relate to a medical device, which is used to administer daily basal insulin to a user (e.g., a patient) of the medical device based on a determined daily total bolus insulin dose and enables the user to easily and simply select one of a plurality of preset bolus insulin doses. The daily total insulin dose and the determined daily total bolus insulin dose are based on the administration information received for the user (e.g., information received from a health care provider). In some embodiments, the plurality of predetermined bolus insulin doses correspond to the doses required for meals with different amounts of carbohydrates, and correspond to a smaller correction dose. In some embodiments, the user's selection of one of the predetermined bolus insulin doses is performed via a button of the medical device. In some embodiments, the user's selection of one of the preset bolus insulin doses is based on the number of times the user pushes the button. In some embodiments, the medical device is configured to provide information about the selected preset bolus insulin dose (e.g., via the vibration of the medical device or a sound emitted by the medical device). In some embodiments, the medical device is configured to receive input from the user to confirm the selected preset bolus insulin dose. In some embodiments, the input confirmation of the selected preset bolus insulin dose is performed via a second button of the medical device.

[0046] Some exemplary embodiments of the present disclosure relate to a medical device for administering daily basal insulin to a user (e.g., a patient) of the medical device based on a determined total daily bolus insulin dose and enabling the user to easily and simply select one of a plurality of preset bolus insulin doses. Some exemplary embodiments of the present disclosure include methods for determining basal insulin and bolus insulin and delivering them to a user (e.g., a patient) of a medical device. Some methods and devices use a simplified control interface to select a bolus insulin dose from a set of preset bolus insulin doses, which are determined by the device based on received dosing information (e.g., based on dosing information received from the user's HCP). In some embodiments, the set of preset bolus insulin doses includes a set of main doses corresponding to meals with different amounts of carbohydrates and a set of smaller correction doses. In some embodiments, the user's selection of one of the predetermined bolus insulin doses is performed via a button of the medical device. In some embodiments, the user's selection of one of the preset bolus insulin doses is based on the number of times the user pushes the button. In some embodiments, the medical device is configured to provide information about the selected preset bolus insulin dose (e.g., via vibration of the medical device or a sound emitted by the medical device). In some embodiments, the medical device is configured to receive an input from a user confirming a selected preset bolus insulin dose. In some embodiments, the input confirming the selected preset bolus insulin dose is performed via a second button of the medical device. In some embodiments, the medical device does not include a graphical user interface. In some embodiments, the control interface for the user does not include a screen or a graphical display.
[0047] In some embodiments, compared with some other conventional medical devices, medical devices are configured to reduce the complexity and difficulty of user selection of bolus insulin dose by using preset bolus insulin dose and by using simplified control interface. For example, compared with some conventional devices, having a single button for selecting bolus insulin dose from a limited number of preset insulin doses reduces the complexity and time required for user input or setting bolus dose, which can increase the ease of use of the device and reduce the errors associated with some user control interfaces. Many conventional medical devices tend to increase the complexity of control interfaces to include more and more options and controls. In some embodiments, compared with some conventional medical devices, the reduction of control interface options on medical devices is counterintuitive, but can lead to more adoption of bolus dose therapy and increase the compliance to bolus dose therapy and the effectiveness of bolus dose therapy.
[0048] In some embodiments, medical device comprises can be activated (for example, press or touch) repeatedly to select preset push insulin dosage from multiple preset insulin dosage.In some embodiments, the dosage in described multiple preset push insulin dosage is determined as different fractions of user's daily total push insulin dosage by medical device.In some embodiments, user's daily total push insulin dosage is provided to medical device and / or is programmed into medical device by a party except user by health care provider.Described multiple dosage can not be linear increase.For example, in some embodiments, described multiple preset insulin push dosage can be 1 / 10, 1 / 5, 1 / 3 and 1 / 2 of daily total push insulin dosage, to correspond to the characterization of meal and less correction.
[0049] In addition, in the embodiment with the second button for confirming dosage, the second button can reduce the error related to inputting dosage and confirming dosage using the same input mechanism. Other embodiments can adopt the button for selecting preset push insulin dosage to confirm selected preset push insulin dosage (for example, by pressing and keeping or touching and keeping button). Other embodiments can adopt different mechanisms to receive the second input to confirm selected preset push insulin dosage. Therefore, the second button is optional.
[0050] In some embodiments, the user is not required to provide any input or information regarding calories, carbohydrates, glycemic index, or blood glucose measurement before selecting the current bolus insulin dose using the button.
[0051] In some embodiments, medical device can reduce the complexity of user interaction, because medical device can apply bolus dosage scheme when blood glucose measurement is not needed and user input blood glucose measurement is not needed.In some embodiments, medical device receives user input corresponding to simplified characterization of meal or physical activity, and the simplified characterization corresponds to one of preset bolus insulin dosage.For example, medical device can receive pressing button three times to indicate small meal, pressing button four times to indicate medium calorie meal or pressing button five times to indicate large meal.Preset bolus insulin dosage can also include smaller correction dose.For example, in some embodiments, user presses button once to select minimum correction dose, and user presses button twice to select larger correction dose.Therefore, in some embodiments, medical device allows calculating meal instead of simpler method of carbohydrate counting, and provides easy selection of smaller correction bolus.This simplification of interaction with user has amazing and beneficial effect on the success rate of medical compliance and bolus dosage therapy, while reducing human error when user selects dosage.
[0052] In some embodiments, after the medical device receives information about the characterization of the meal (e.g., by the number of times a button is pressed), the medical device can provide an indication of the selection by vibration, sound, and / or visual indication. For example, in some embodiments, if the button is pressed four times to remind the user that the fourth preset push insulin dose is selected, the medical device can vibrate four times. In some embodiments, this indication of the selection via vibration, sound, and / or visual indication can be important because the simplified control interface of the medical device may not include a screen or a graphical display. In some embodiments, after indicating the selection, the medical device may require the user to press the button for selection again to confirm the selection before applying the selected push dose. In some embodiments, the input mechanism for confirming the dose is different from the button for selecting the dose. For example, in some embodiments, the medical device includes a second button activated by the user (e.g., pressed or touched), thereby confirming the selection of the dose before the dose is applied. This confirmation process can reduce errors in dose selection and administration.
[0053] FIG. 1 is a block diagram of a medical device 100 (hereinafter referred to as “device 100”) according to some embodiments. The medical device 100 includes an insulin pump 102 configured to deliver insulin to a user (e.g., a patient), a control interface 108 including a button 109 (e.g., a push button) configured to select one of a plurality of preset push insulin doses based on input from the user, and a controller 104 configured to execute machine-readable instructions stored in a memory 106. In some embodiments, the control interface 108 includes a second button 120 for confirming the selection of the preset push insulin dose. In other embodiments, confirmation of the selection may also be performed via the button 109.
[0054] In some embodiments, the preset bolus insulin dose is determined by the medical device at least in part based on received dosing information about the user (e.g., information received from a health care provider), which is used to determine the user's total daily insulin dose and the total daily bolus insulin dose. In some embodiments, the dose in the multiple preset bolus insulin doses is determined as a fraction of the total daily bolus insulin dose. In some embodiments, the preset bolus insulin doses in the multiple bolus insulin doses do not increase linearly. In some embodiments, the preset bolus insulin doses correspond to meals with different carbohydrate amounts (e.g., large, medium, and small) and smaller correction doses, so that the user can simply and easily select the preset bolus insulin dose corresponding to the meal or select a smaller correction bolus insulin dose.
[0055] In some embodiments, the medical device 100 includes a glucose measurement sensor 112 configured to measure the blood sugar of the user. In other embodiments, the glucose measurement sensor 112 is not included in the medical device, which is why the glucose measurement sensor 112 is indicated in the figure by a box with a dashed line.
[0056] Examples of insulin pump 102 include, but are not limited to, a patch pump worn by a user and an implantable device that delivers a dose of insulin to the bloodstream. In some embodiments, insulin pump 102 is configured to deliver short-acting insulin. In some embodiments, insulin pump 102 is configured to deliver short-acting and / or long-acting insulin.
[0057] In some embodiments, button 109 and / or second button 120 are mechanical switches or electromechanical switches that generate signals when activated. In other embodiments, button 109 and / or second button 120 are capacitive or inductive touch interfaces. In some embodiments, the number of buttons activated by the user during the selection time period determines which of the multiple preset push insulin doses is selected. For example, pressing button 108 five times will select the fifth preset push insulin dose. In some embodiments, the number of preset push insulin doses is five or less than five. In some embodiments, the number of preset push insulin doses is six or less than six. In some embodiments, the number of activations of button 109 for selecting any preset push insulin dose is less than six. In some embodiments, the number of activations of button 109 for selecting any preset push insulin dose is less than seven. Limiting the number of preset push insulin doses simplifies the selection process for the user.
[0058] In some embodiments, the control interface 108 is also configured to provide information indicating the selected preset bolus insulin dose to the user. In some embodiments, the information is provided via the vibration of the medical device. In some embodiments, the information is provided via the sound generated by the medical device.
[0059] In some embodiments, the controller 104 can receive a second input confirming the selected preset push insulin dose from the control interface 108. For example, in some embodiments, the control interface 108 includes a second button 120, and after the preset push insulin dose is selected using the button 108 (e.g., the push button), the user activates the second button 120 (e.g., by pressing or touching the second button), thereby providing a second input to confirm the selected preset push insulin dose. However, some other embodiments of the medical device do not include a second button for confirmation. For example, in some embodiments, the button 108 for selecting the preset push insulin dose can also be used for a second input to confirm the selected preset push insulin dose (e.g., pressing and holding or touching and holding the button 108 for at least a certain period of time can be used to confirm the selected preset push insulin dose). In some embodiments, after the medical device provides information indicating the selected preset push insulin dose to the user (e.g., via one or more of vibration, sound or visual indicators), a second input confirming the selected preset push insulin dose is received.
[0060] In some embodiments, the control interface 108 for the user to use when selecting and confirming the preset bolus insulin dose does not include a graphical user interface. This can be advantageous for users who do not wish to use a separate device (such as a smart phone, etc.). The control and response of the device are greatly simplified. However, in some embodiments, the device can be configured to communicate with a smart phone, etc. while keeping the control interface 108 active.
[0061] In some embodiments, the controller 104 includes a processor, a field programmable gate array, an application specific integrated circuit, a microcontroller, a peripheral interface controller (PIC), etc. In some embodiments, the controller 104 is connected to the memory 106 interface via a bus. The memory 106 can be any form of memory for storing instructions or data. Examples of the memory 106 include, but are not limited to, solid-state memory, computer-readable media such as flash memory, etc.
[0062] In some embodiments, the medical device also includes an input interface for receiving information about the user (e.g., from a health care provider). In some embodiments, the input interface 110 can be configured for wired communication and / or short-range wireless communication (e.g., via Bluetooth connection) or long-range wireless communication (e.g., via cellular). In some embodiments, the input interface 110 is used to receive dosage information to customize the device for the user. In some embodiments, the input interface 110 is an input / output interface for realizing two-way communication (e.g., with a health care provider). In some embodiments, the input interface 110 can be a universal serial bus interface, an IEEE 1394 interface, a wireless interface adapted to send and receive information. In an example, the input interface 110 can be configured to receive input from a health care professional to program the medical device 100.
[0063] For example, in some embodiments, medical device receives information (for example, from HCP) to program medical device 100 with the dosage information of the user.Medical device 100 determines the daily total basal insulin dosage and the daily total push insulin dosage of the user according to the dosage information received.In some embodiments, the information received includes information about at least two of the following: the daily total insulin dosage of the user, the daily total basal insulin dosage of the user, the daily total push insulin dosage of the user and the daily total basal insulin dosage ratio of the user and the daily total push insulin dosage.For example, in some embodiments, the information received (for example, from HCP, for programming the device) includes information about the daily total insulin dosage and about the daily total basal insulin dosage of the user and the daily total push insulin dosage ratio of the user.In some embodiments, include at least one of the following in the information received: the daily total insulin dosage of the user, the daily total basal insulin dosage of the user and the daily total push insulin dosage of the user, and the device assumes that the daily total basal insulin dosage equals the daily total push insulin dosage.
[0064] In some embodiments, the HCP initially interacts with the medical device 100 using a computer or mobile device to program the medical device 100. In some examples, the HCP can provide information to customize the total daily insulin dose and the total daily bolus insulin dose for the user based on the user's (e.g., patient's) profile, etc. In some embodiments, the controller 104 uses the information received from the HCP to reprogram the medical device 100 to customize the treatment for the user.
[0065] In some embodiments, the controller executes instructions stored in the memory to determine the user's daily total basal insulin dose and daily total bolus insulin dose based on the information received about at least two of the following items: the user's daily total insulin dose, the user's daily total basal insulin dose, the user's daily total bolus insulin dose and the user's daily total basal insulin dose and the daily total bolus insulin dose ratio. For example, the received information (e.g., from the HCP) can include the user's daily total insulin dose and the daily total basal insulin dose and the daily total bolus insulin ratio, from which the daily total basal insulin dose and the daily total bolus insulin dose are determined. In the example, based on the received user information, the controller 100 can provide 50% of the user's daily insulin demand via basal insulin delivery, and distribute another 50% for delivery via multiple preset bolus insulin doses that the user can select using button 109.
[0066] In some embodiments, controller 104 determines the basal insulin delivery rate based at least in part on the daily total basal insulin dosage. In some embodiments, controller 104 determines the size of micro-bolus insulin dosage and is used to apply micro-bolus insulin dosage to reach the frequency of determined basal insulin delivery rate. Instruction can include the process of determining the number of times that insulin pump 102 must be operated per hour and the amount of micro-bolus insulin dosage during each operation, the unit time between micro-bolus insulin dosage, etc. In some embodiments, insulin pump 102 can operate continuously to deliver continuous basal insulin rate to the user. For different types of insulin (such as short-acting insulin, long-acting insulin, etc.), the process for determining the basal insulin delivery rate can be different. For example, in some embodiments, the process can be based on the following determination of the number of minutes between micro-bolus:
[0067] Minutes between microboluses=60 min / (TDBasal [μL] / 24 h / Vol microbolus [μL]), where TDBasal is the total daily basal insulin dose and microbolus is the volume of insulin delivered each time the insulin pump 102 is activated.
[0068] Controller 104 determines multiple preset push insulin doses based on total push insulin dose per day at least in part. For example, in some embodiments, instruction includes a process for determining the multiple preset push insulin doses based on total push insulin dose per day. The following includes the non-limiting example of such process. In an embodiment, the process is divided into multiple preset push insulin doses by total push insulin dose per day. In some embodiments, the multiple preset push insulin doses can be five preset push insulin doses, such as 5% of total push insulin dose per day (TDBolus) for slight correction, 12.5% of TDBolus for major correction, 20% of TDBolus for small meals (a small amount of carbohydrates (CHO)), 35% of TDBolus for medium meals (a medium amount of CHO) and 50% of TDBolus for large meals (a large amount of CHO). The preset push insulin doses of other quantities and other divisions of total push insulin dose per day also fall within the scope of the present disclosure. Table 1 below includes non-limiting example segmentation of total push insulin dose per day and the estimated impact on blood glucose level calculated.
[0069] For Table 1, it is assumed that the total daily basal insulin dose is approximately equal to the total daily bolus insulin dose, and the total daily carbohydrate intake is 240 grams. It is assumed that the average expected effect of insulin dose on blood glucose follows the 1600 rule below: dBG = 1600 / DIR,
[0070] Where dBG is the drop in blood glucose in mg / ml and DIR is the daily insulin requirement. Some people have higher insulin or lower insulin sensitivity, which may not be accurately characterized by the "1600 rule" equation above.
[0071] In this example, because the total daily basal insulin dose and the total daily bolus insulin dose are approximately equal, the respective preset sizes also reflect similarly proportioned basal rates.
[0072] In an example, the controller 104 can receive a signal from the push button 108. For example, the user can characterize a meal after a meal, characterize a correction based on exercise before or after a meal, characterize exercise between this meal and the previous meal, etc. by activating the push button 108. The controller 104 can use the number of times the push button 108 is activated within a predetermined time period to characterize a meal, exercise, or both. In an example, the predetermined time period can be a few seconds after the push button 108 is activated for the first time. The controller 104 can determine the number of times the push button 108 is pressed to select a push insulin dose from a set of push insulin presets to be administered. For example, the controller 104 can determine that the push insulin dose to be administered after four activations of the push button is a push insulin dose for the fourth preset push insulin dose, which is a Chinese meal for the example in Table 1. In some embodiments, the controller 104 can receive a signal from the second button 121 to confirm the preset push insulin dose selected using the push button 108. The controller 104 may activate the insulin pump 102 to deliver the selected bolus insulin dose to the user, which in some embodiments is a selected and confirmed preset bolus insulin dose.
[0073] In an example, button 108 may be activated to characterize a meal.
[0074] The use of bolus button 108 allows controller 104 to receive information about a user's meal for selection of a preset bolus insulin dose without requiring the user to categorize the meal using complex methods such as carbohydrate counting, personal dose dials or settings, etc.
[0075] In some embodiments, the activation frequency of the push button 108 is based on the characterization of the meal. For example, as described above, for the embodiments of the preset push insulin dose shown in Table 1, the user can activate the push button 108 four times to indicate a moderate meal. Similarly, the activation frequency of the push button 108 can be based on the characterization of the user's physical activity (e.g., the user's physical activity before a meal, between a previous meal and a current meal, etc.). Similarly, the activation frequency of the push button 108 can be based on the characterization of the user's physical activity and the previous meal.
[0076] In some embodiments, glucose measurement sensor 112 may be interfaced with controller 104 to determine a user's blood glucose level prior to administering a bolus insulin dose to the user.
[0077] In some embodiments, the medical device 100 is configured to receive at least one reservoir containing insulin. In some embodiments, the medical device 100 is configured to receive more than one reservoir, each reservoir containing a different type of insulin.
[0078] Fig. 2A and Fig. 2B schematically depict an exemplary medical device 100 according to some embodiments. The exemplary medical device 100 may include a control unit 202 and a pump unit 204. In some embodiments, the control unit 202 includes a controller 104, a memory 106, and a control interface 108, the control interface including a button 109 (e.g., a push button) for selecting a preset push insulin dose from a plurality of preset push insulin doses. As described above, in some embodiments, the control interface 108 also provides information indicating the selected preset push insulin dose to the user (e.g., via one or more of a vibration, sound, or visual indicator). In some embodiments, the control interface 108 also includes a second button 120 for receiving a second input to confirm the selected preset push insulin dose. For example, in some embodiments, the user activates (e.g., presses or touches) button 108 one or more times to select the current bolus insulin dose, the medical device provides an indication of the selected preset bolus insulin dose (e.g., via one or more of a vibration, sound, or visual indicator), and then the user activates (e.g., presses or touches) second button 120 to confirm the selected preset bolus insulin dose. In some embodiments, the selected dose is confirmed using button 108 or some other element of control interface 108, for example, pressing and holding button 108 can be used to confirm the selected dose. In some embodiments, second button 120 is used as a start / stop button for delivering insulin.
[0079] In embodiments requiring confirmation, the selected preset bolus insulin dose will only be delivered to the user if a second input of confirmation is received. In some embodiments, the second input for confirmation must be received within a preset confirmation time after selecting the preset bolus insulin dose.
[0080] In some embodiments, the control unit 202 includes the glucose measurement sensor 112. However, in other embodiments, no glucose measurement sensor is included, which is why the glucose measurement sensor 112 is indicated by a dashed line in Figures 2A and 2B.
[0081] The pump unit 204 includes at least one insulin pump 102, which may be a patch pump, an implantable pump, or any other pump for delivering insulin to a user. In some embodiments where more than one different type of insulin may be delivered to a user, the pump unit 204 may include more than one pump, each pump dispensing a different type of insulin.
[0082] In some embodiments, the control unit 202 further includes at least one power source 208 (e.g., a battery) and at least one drive unit 206 (see FIG. 2B ) for mechanically actuating at least one insulin pump 102. In other embodiments, at least one drive unit 206 may not be included in the control unit.
[0083] In some embodiments, the control unit 202 is coupled or coupleable by a user to the pump unit 204. In some embodiments, the control unit 202 and / or the pump unit 204 include a coupling for coupling the units together. In other embodiments, the control unit 202 and the pump unit 204 are not intended to be detachable or not detachable by a user without damaging or rendering the medical device inoperable.
[0084] As described above, the controller 104 may determine the basal insulin delivery rate based at least in part on the total daily basal insulin dose. The controller 104 may provide a signal or instruction to the drive unit 206 that causes the drive unit to mechanically actuate the insulin pump 102 of the pump unit 204 to deliver insulin to the user at the basal insulin delivery rate via the insulin pump 102. After selecting the preset basal insulin dose, the controller 104 may provide a signal or instruction to the drive unit 206 that causes the drive unit to mechanically actuate the insulin pump 102 of the pump unit 204 to deliver the selected bolus insulin dose to the user via the insulin pump 102.
[0085] Fig. 3 shows a flowchart 300 of an exemplary method for determining a user's basal insulin delivery rate and a bolus insulin dose. The total daily basal insulin dose and the total daily basal insulin dose are determined by the controller 104 based on the administration information of the user received via the input interface 109 of the control unit 202 (step 302). In some embodiments, the administration information includes at least two of the following: (i) the user's total daily insulin dose; (ii) the user's total daily basal insulin dose; (iii) the daily total bolus insulin dose per user; and (iv) the user's total daily basal insulin dose to the daily total bolus insulin dose ratio. For example, in some embodiments, the administration information includes the user's total daily insulin dose and the user's total daily basal insulin dose to the daily total bolus insulin dose ratio. In some embodiments, the medical device is configured based on the assumption that the total daily basal insulin dose is the same as the daily total bolus insulin dose, in which case the received information may include only one or more of the following: (i) the user's total daily insulin dose; (ii) the user's total daily basal insulin dose; and (iii) the user's total daily bolus insulin dose.
[0086] The controller 104 of the control unit 202 determines a plurality of preset bolus insulin doses based at least in part on the user's determined total daily bolus insulin dose for selection using the button 109 of the control interface 108 of the control unit 202 (step 304).
[0087] The controller 104 of the control unit 202 determines a basal insulin delivery rate based at least in part on the determined total daily basal insulin dose (step 306 ).
[0088] In some embodiments where the method is also a method for delivering basal insulin and delivering bolus insulin, the method further includes: the controller 104 actuates the insulin pump 102 of the pump unit 204 via the drive unit 206 to deliver insulin to the user via the insulin pump 102 at the basal insulin delivery rate (step 308).
[0089] The controller 104 of the control unit 202 receives a first input from a user via a button 109 of a control interface 109 of the control unit, the first input selecting one of the plurality of preset bolus insulin doses (step 310).
[0090] In some embodiments, the controller provides an indication (eg, a vibration, audio, and / or visual indication) of the selected preset bolus insulin dose to the user via the control interface 202 (step 311).
[0091] In some embodiments, the controller 104 receives a second input from the user confirming the selected preset bolus insulin dose via the control interface 108 within the confirmation time period after selecting the preset bolus insulin dose (step 312). For example, the second input can come from the user pressing or touching the second button 120 to confirm the selected preset bolus insulin dose after the medical device provides an indication to the user of the selected preset bolus insulin dose.
[0092] In some embodiments where the method is also a method of delivering basal insulin and delivering bolus insulin, the method further comprises: actuating the insulin pump 102 via the drive unit 206 to deliver the selected bolus insulin dose to the user (step 314). In FIG. 3 , steps that may not be performed in some embodiments are indicated with dashed lines.

[0100] The terms "drug" or "medicament" are used synonymously herein and describe a pharmaceutical preparation comprising one or more active pharmaceutical ingredients or a pharmaceutically acceptable salt or solvate thereof and optionally a pharmaceutically acceptable carrier. In the broadest sense, an active pharmaceutical ingredient ("API") is a chemical structure that has a biological effect on humans or animals. In pharmacology, a drug or medicament is used to treat, cure, prevent, or diagnose disease or to otherwise enhance physical or mental health. A drug or medicament may be used for a limited duration, or periodically for a chronic disorder.
[0101] As described below, a drug or medicament may include at least one API or a combination thereof in various types of formulations for treating one or more diseases. Examples of APIs may include small molecules (having a molecular weight of 500 Da or less); polypeptides, peptides, and proteins (e.g., hormones, growth factors, antibodies, antibody fragments, and enzymes); carbohydrates and polysaccharides; and nucleic acids, double-stranded or single-stranded DNA (including naked and cDNA), RNA, antisense nucleic acids (such as antisense DNA and RNA), small interfering RNA (siRNA), ribozymes, genes, and oligonucleotides. Nucleic acids may be incorporated into molecular delivery systems (such as vectors, plasmids, or liposomes). Mixtures of one or more drugs are also contemplated.
[0102] The drug or medicament can be included in a primary package or "drug container" adapted for use with a drug delivery device. The drug container can be, for example, a cartridge, a syringe, a reservoir or other solid or flexible vessel, which is configured to provide a suitable chamber for storing (for example, short-term or long-term storage) one or more drugs. For example, in some cases, the chamber can be designed to store the drug for at least one day (for example, 1 day to at least 30 days). In some cases, the chamber can be designed to store the drug for about 1 month to about 2 years. Storage can be carried out at room temperature (for example, about 20 ° C) or refrigerated temperature (for example, from about -4 ° C to about 4 ° C). In some cases, the drug container can be or can include a dual-chamber cartridge, which is configured to store two or more components (for example, API and diluent, or two different drugs) of a pharmaceutical preparation to be administered separately, one of which is stored in each chamber. In such cases, the two chambers of the dual-chamber cartridge can be configured to allow mixing between two or more components before and / or during distribution to the human or animal body. For example, the two chambers can be configured so that they are in fluid communication with each other (e.g., through a conduit between the two chambers) and allow the user to mix the two components if desired before dispensing. Alternatively or additionally, the two chambers can be configured to allow mixing when dispensing the components into the human or animal body.
[0103] The medicine or medicament contained in the drug delivery device as described herein can be used to treat and / or prevent many different types of medical disorders. The example of obstacle includes, for example, diabetes or complications associated with diabetes (such as diabetic retinopathy), thromboembolic disorders (such as deep vein or pulmonary thromboembolism). Another example of obstacle is acute coronary syndrome (ACS), angina pectoris, myocardial infarction, cancer, macular degeneration, inflammation, hay fever, atherosclerosis and / or rheumatoid arthritis. The example of API and medicine is those as described in the following manual: such as Rote Liste 2014 (for example, but not limited to, main group (main group) 12 (antidiabetic drugs) or 86 (tumor drugs)) and Merck Index, the 15th edition.

As used herein, the terms "analogs" and "derivatives" refer to polypeptides having a molecular structure that can be formally derived from the structure of a naturally occurring peptide (e.g., the structure of human insulin) by deleting and / or exchanging at least one amino acid residue present in a naturally occurring peptide and / or by adding at least one amino acid residue. The added and / or exchanged amino acid residues can be codable amino acid residues or other naturally occurring residues or purely synthetic amino acid residues. Insulin analogs are also referred to as "insulin receptor ligands." In particular, the term "derivative" refers to a polypeptide having a molecular structure that is formally derived from the structure of a naturally occurring peptide (e.g., the structure of human insulin) in which one or more organic substituents (e.g., fatty acids) are bound to one or more amino acids. Alternatively, one or more amino acids present in the naturally occurring peptide may have been deleted and / or replaced by other amino acids (including non-encodable amino acids), or amino acids (including non-encodable amino acids) have been added to the naturally occurring peptide.

[0112] As used herein, the term "antibody" refers to an immunoglobulin molecule or an antigen binding portion thereof. Examples of antigen binding portions of immunoglobulin molecules include F (ab) and F (ab') 2 fragments, which retain the ability to bind antigens. The antibody can be a polyclonal antibody, a monoclonal antibody, a recombinant antibody, a chimeric antibody, a deimmunized antibody or a humanized antibody, a fully human antibody, a non-human (e.g., mouse) antibody or a single-chain antibody. In some embodiments, the antibody has effector functions and can fix complement. In some embodiments, the antibody has reduced or no ability to bind Fc receptors. For example, the antibody can be an isotype or subtype, an antibody fragment or a mutant, which does not support binding to Fc receptors, for example, it has a mutagenic or missing Fc receptor binding region. The term antibody also includes antigen binding molecules based on tetravalent bispecific tandem immunoglobulins (TBTI) and / or dual variable region antibody-like binding proteins with cross-binding region orientation (CODV).
[0113] The term "fragment" or "antibody fragment" refers to a polypeptide (e.g., antibody heavy chain and / or light chain polypeptide) derived from an antibody polypeptide molecule, which does not include a full-length antibody polypeptide, but still includes at least a portion of a full-length antibody polypeptide capable of binding an antigen. Antibody fragments may include cleavage portions of full-length antibody polypeptides, although the term is not limited to such cleavage fragments. Antibody fragments that can be used in the present invention include, for example, Fab fragments, F(ab')2 fragments, scFv (single-chain Fv) fragments, linear antibodies, monospecific or multispecific antibody fragments (e.g., bispecific, trispecific, tetraspecific and multispecific antibodies (e.g., diabodies, triabodies, tetrabodies)), monovalent or multivalent antibody fragments (e.g., bivalent, trivalent, tetravalent and multivalent antibodies), mini antibodies, chelated recombinant antibodies, triabodies or bibodies, intracellular antibodies, nanobodies, small modular immunopharmaceuticals (SMIPs), binding domain immunoglobulin fusion proteins, camelized antibodies and antibodies containing VHH. Other examples of antigen-binding antibody fragments are known in the art.
[0114] The term "complementarity determining region" or "CDR" refers to short polypeptide sequences within the variable region of both heavy and light chain polypeptides that are primarily responsible for mediating specific antigen recognition. The term "framework region" refers to amino acid sequences within the variable region of both heavy and light chain polypeptides that are not CDR sequences and are primarily responsible for maintaining the correct positioning of the CDR sequences to allow antigen binding. Although the framework region itself is generally not directly involved in antigen binding, as is known in the art, certain residues within the framework region of certain antibodies may be directly involved in antigen binding or may affect the ability of one or more amino acids in the CDR to interact with the antigen.
[0115] Examples of antibodies are anti-PCSK-9 mAb (eg, Alirocumab), anti-IL-6 mAb (eg, Sarilumab), and anti-IL-4 mAb (eg, Dupilumab).
