Description

Technical Field

[0001] The present application relates to the field of medical technology, and in particular to an insulin infusion device, a device control method, and a readable storage medium. Background Art

[0002] Diabetes is a common metabolic endocrine disease, which refers to a chronic metabolic disorder caused by the inability of the human pancreas to produce sufficient amounts of the hormone insulin, resulting in hyperglycemia, that is, the presence of excessive glucose in the plasma. Diabetes cannot be cured and requires permanent insulin treatment to keep the blood sugar level of diabetic patients within the normal range.

[0003] At present, insulin cannot be taken orally, and insulin infusion equipment is needed to infuse insulin into the body to adjust blood sugar levels. Insulin infusion is a very complicated operation. The traditional quantitative insulin injection according to doctor's orders cannot meet the real needs of patients, resulting in increasingly serious complications of diabetes. With the development of intelligent technology, more and more scenarios require the use of more intelligent insulin infusion equipment to meet the real needs of users to adjust insulin infusion.

[0004] However, insulin infusion devices usually need to be used for 24 hours or longer. If the insulin infusion device is used all the time, the power consumption will greatly affect the use time of the insulin infusion device, and frequent replacement of power supply will also directly affect blood sugar control. Therefore, how to extend the use time of insulin infusion devices and provide safer and more reliable insulin infusion devices are problems that need to be solved urgently. Summary of the invention

In this way, the user does not need to use physical buttons to control the insulin infusion device, but can control the insulin infusion device more intuitively and quickly through the touch screen, which simplifies the operation steps and improves the human-computer experience. Furthermore, since the processor is independently coupled to the first touch-sensitive area and the second touch-sensitive area, respectively, and the processor includes a low-power mode and a full working mode, the processor can enter the low-power mode according to predefined conditions, and in response to a first interactive input to the first touch-sensitive area during the operation of the low-power mode, switch the low-power mode to the full working mode, and in response to a second interactive input to the first touch-sensitive area and / or a third interactive input to the second touch-sensitive area during the operation of the full working mode, execute a preset function, and the preset function includes at least one of high-dose infusion, basal rate infusion, stop infusion, pause infusion, reset filling, user settings, and screen unlocking. Therefore, the first touch-sensitive area and the second touch-sensitive area are independently controlled. On the one hand, during the operation of the low-power mode, the processor will switch the low-power mode to the full working mode only when the first touch-sensitive area receives a wake-up input, which fully takes into account the interference of human error operations, avoids other accidental touches from changing the low-power mode, and ensures an effective wake-up operation. Moreover, the first touch-sensitive area and the second touch-sensitive area need to be used together to realize the preset function. In this way, even if the user accidentally touches the first touch-sensitive area or the second touch-sensitive area alone, the insulin infusion device will not perform the corresponding action, which also improves the safety and reliability of the insulin infusion device. On the other hand, the low-power mode is a mode in which at least one processor enters a dormant state. Entering the low-power mode in time under predefined conditions can extend the use time of the insulin infusion device. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0071] FIG1 is a schematic diagram of an insulin infusion device in an embodiment. In an exemplary embodiment, as shown in FIG1 , an insulin infusion device 100 is provided. The insulin infusion device 100 includes a housing 101 , a touch screen 102 , and at least one processor (not shown in FIG1 ).

[0072] The touch screen 102 refers to a display capable of touch interaction, and the touch interaction may include but is not limited to gesture touch, capacitive pen touch, etc. The touch screen 102 is disposed on the housing 101, and the processor is disposed in the housing 101. It should be noted that the material and shape of the housing 101 are not limited in this embodiment.

[0073] The touch screen 102 includes a first touch sensitive area 102a and a second touch sensitive area 102b. Referring to FIG1 , the first touch sensitive area 102a may be a white dotted rectangular area at the bottom of FIG1 , and the second touch sensitive area 102b may be a white dotted rectangular area at the top of FIG1 .

[0074] Furthermore, the processor is independently coupled to the first touch-sensitive area 102a and the second touch-sensitive area 102b, that is, the processor is connected to the first touch-sensitive area 102a and the second touch-sensitive area 102b, respectively, and the first touch-sensitive area 102a and the second touch-sensitive area 102b are independently set, and the processor can control the first touch-sensitive area 102a and the second touch-sensitive area 102b, respectively.

[0075] The first touch-sensitive area 102a and the second touch-sensitive area 102b are used to receive interactive inputs implemented by the user. The interactive inputs may include but are not limited to long press inputs, short press inputs, click inputs, sliding inputs or other gestures and any other input forms, which are not limited in this embodiment.

[0076] Further, the processor includes a low power mode and a full working mode. Among them, the low power mode is a mode in which at least one processor enters a sleep state. It is understandable that the processor entering the sleep state can reduce power consumption. Exemplarily, the processor may include a main control microcontroller unit (MCU). In the low power mode, the main control MCU can turn off or reduce the backlight of the touch screen 102, and can also control the driving mechanism in the insulin infusion device 100 to stop working and not perform infusion work. In this way, the low power mode can reduce the energy consumption loss of the insulin infusion device 100 in a non-full working state and extend the service life of the insulin infusion device 100.

[0077] In some embodiments, in the low power mode, the external drive device of the insulin infusion device 100 can be controlled to stop working, for example, stop supplying power to the external drive device, so as to further reduce power consumption. The external drive device may also include but is not limited to at least one of a buzzer, a rotor motor or a touch screen 102 in the insulin infusion device 100. The buzzer is used to realize the buzzer alarm of the insulin infusion device 100, and the rotor motor is used to realize the vibration alarm of the insulin infusion device 100.

[0078] For example, in the low power mode, the touch screen 102 and the driving mechanism in the insulin infusion device 100 can be in a power-off state. The processor can control the power on and off of the driving mechanism and the touch screen 102 by controlling the power enable of the driving mechanism and the touch screen 102.

[0079] Furthermore, the processor will enter the low power mode according to a predetermined condition. Optionally, the predefined condition may be that the power supply voltage of the power supply in the insulin infusion device 100 is lower than a voltage threshold, or that the user's instruction is received, or that the insulin infusion device 100 does not perform the infusion function within a preset time period and does not receive the user's interactive input. In some embodiments, the low power mode may also be automatically entered during the infusion interval, such as during the infusion interval of a large dose infusion, and the processor automatically enters the low power mode, which is not limited in this embodiment.

[0080] The full working mode refers to the normal working state of the insulin infusion device 100. In the full working mode, the external drive device of the insulin infusion device 100 can work normally. Further optionally, in the full working mode, the processor controls the power supply to supply power to the external drive device. Exemplarily, in the full working mode, the processor controls the power supply to supply power to the touch screen 102 and the drive mechanism, and the touch screen 102 can be in a bright screen state, and the drive mechanism is in a movable state.

[0081] In some embodiments, the insulin infusion device 100 may further include a screen-off mode. In the screen-off mode, the touch screen 102 of the insulin infusion device 100 is in a screen-off state. For example, the insulin infusion device 100 may enter the screen-off mode after not receiving any interactive input from the user to the touch screen 102 within a preset time.

[0082] In this embodiment, the first touch-sensitive area 102a can be used as a touch-sensitive area for receiving a main control input to switch between a low power mode and a full working mode of the insulin infusion device 100. The second touch-sensitive area 102b is used to display a human-computer interaction interface.

[0083] Furthermore, the processor can respond to a first interactive input to the first touch-sensitive area 102a during the low-power mode operation to control the insulin infusion device 100 to switch from the low-power mode to the full-operation mode, that is, to switch the low-power mode to the full-operation mode. The first interactive input is a preset interactive input, such as a press input.

[0084] For example, when the insulin infusion device 100 is in the low power mode, the first touch-sensitive area 102a can be in the screen-off state. Taking the first interactive input as a pressing input as an example, in this case, the user can press the first touch-sensitive area 102a to switch the insulin infusion device 100 from the low power mode to the full working mode. When the insulin infusion device 100 is in the full working mode, the second touch-sensitive area 102b can be in the screen-on state.

[0085] Furthermore, when the insulin infusion device 100 is in the full working mode, the processor is used to respond to the second interactive input to the first touch sensitive area 102a and / or the third interactive input to the second touch sensitive area 102b during the full working mode to execute the preset function of the insulin infusion device 100. The preset function includes but is not limited to at least one of bolus infusion, basal rate infusion, stop infusion, pause infusion, reset filling, user settings, and screen unlocking.

[0086] Among them, the second interaction input and the third interaction input are also preset interaction inputs. For example, the second interaction input may include a long press input, and the third interaction input may include a click input. This embodiment is not limited to this.

[0087] Bolus infusion refers to the infusion of a larger dose within a certain period of time in response to special needs for large-dose insulin infusion such as eating. Bolus infusion can include conventional bolus infusion, square wave infusion or dual wave infusion. Among them, conventional bolus infusion means that the infusion is completed in one go. Square wave bolus infusion means that the infusion is completed within the infusion time. Dual wave bolus infusion includes conventional bolus infusion and square wave infusion. For example, if the user needs to infuse 7U immediately and 5U within 2h, dual wave bolus infusion can be used.

[0088] Basal rate infusion refers to a continuous micro-infusion over a certain period of time, which is used to maintain daily metabolism. Basal rate infusion can include regular basal rate infusion or temporary basal rate infusion. Among them, regular basal rate infusion can be used to meet the metabolic needs of daily periods, while temporary basal rate infusion can be used to maintain the metabolic needs of temporary periods. For example, the user can control the insulin infusion device 100 to perform regular basal rate infusion during normal times, and can control the insulin infusion device 100 to perform temporary basal rate infusion when on a business trip.

[0089] Stopping infusion can be understood as prohibiting infusion. Pausing infusion can be understood as ending or canceling infusion. User settings refer to configuring parameters for the insulin infusion device 100. For example, the user can set the time, date, alarm mode, etc. of the insulin infusion device 100. Screen unlocking refers to unlocking the touch screen 102 to obtain the right to use the insulin infusion device 100.

[0090] The reset filling is used to complete the automatic filling of the pipeline after replacing a new reservoir of the insulin infusion device 100. If the insulin in the insulin infusion device 100 is used up, the user will generally load a new reservoir for the insulin infusion device 100, and the insulin in the reservoir may not be fully loaded, and there may be a certain amount of air. Therefore, the process of discharging excess air in the reservoir so that subsequent accurate infusion can be performed can be reset filling.

[0091] In the above-mentioned insulin infusion device 100, the insulin infusion device 100 includes a housing 101, a touch screen 102, and at least one processor. Among them, the touch screen 102 is arranged on the housing 101, and the touch screen 102 includes a first touch-sensitive area 102a and a second touch-sensitive area 102b, and the first touch-sensitive area 102a and the second touch-sensitive area 102b are used to receive interactive input implemented by the user. In this way, the user does not need to use physical buttons to control the insulin infusion device 100, but can control the insulin infusion device 100 more intuitively and quickly through the touch screen 102, which simplifies the operation steps and improves the human-computer experience. Furthermore, since the processor is independently coupled to the first touch-sensitive area 102a and the second touch-sensitive area 102b, respectively, and the processor includes a low-power mode and a full-operation mode, the processor can enter the low-power mode according to predefined conditions, and in response to a first interactive input to the first touch-sensitive area 102a during the operation of the low-power mode, switch the low-power mode to the full-operation mode, and in response to a second interactive input to the first touch-sensitive area 102a and / or a third interactive input to the second touch-sensitive area 102b during the operation of the full-operation mode, execute a preset function, the preset function including at least one of large-dose infusion, basal rate infusion, stop infusion, pause infusion, reset filling, user settings, and screen unlocking. Therefore, the first touch-sensitive area 102a and the second touch-sensitive area 102b are independently controlled. On the one hand, during the operation of the low-power mode, the processor will switch the low-power mode to the full-operation mode only when the first touch-sensitive area 102a receives a wake-up input, which fully takes into account the interference of human error operations, avoids other accidental touches from changing the low-power mode, and ensures an effective wake-up operation. In addition, the first touch-sensitive area 102a and the second touch-sensitive area 102b need to be used together to realize the preset function. In this way, even if the user accidentally touches the first touch-sensitive area 102a or the second touch-sensitive area 102b alone, the insulin infusion device 100 will not perform the corresponding action, which also improves the safety and reliability of the insulin infusion device 100. On the other hand, the low-power mode is a mode in which at least one processor enters a dormant state. Entering the low-power mode in time under predefined conditions can extend the use time of the insulin infusion device 100.

[0092] Furthermore, in some related technologies, in order to improve the safety of the use of insulin infusion devices, the touch screen of the insulin infusion device will be locked under certain specific operations until the specific operation is completed and then unlocked. In this way, during the period of locking the touch screen, the touch screen of the insulin infusion device will no longer respond to any input, so as to improve the safety of use. However, the above method limits other inputs of the user during the period of locking the touch screen, and the flexibility is not high. After entering the low-power mode under predefined conditions, the first touch-sensitive area 102a can be used to switch the low-power mode to the full working mode in a timely manner in this embodiment. After entering the full working mode, the preset functions can still be realized by using the first touch-sensitive area 102a and the second touch-sensitive area 102b in combination, which can not only avoid accidental touches by the user to improve safety, but also improve the flexibility of use.

[0093] Figure 2 FIG. 1 is a schematic diagram of a screen unlocking method in an embodiment, such as Figure 2 As shown, in an exemplary embodiment, optionally, when the insulin infusion device 100 is in the full working mode, that is, during the operation of the full working mode, the processor is used to unlock the screen of the second touch-sensitive area 102b according to the user's interactive input to the lock screen graphic element 201 displayed in the second touch-sensitive area 102b. For example, the user can long press the lock screen graphic element 201 to unlock the screen.

[0094] Further optionally, the processor is used to display the unlock graphic element 202 in the second touch-sensitive area 102b based on the user's interactive input to the lock screen graphic element 201 in the second touch-sensitive area 102b, and to unlock the screen lock of the second touch-sensitive area 102b based on the user's interactive input to the unlock graphic element 202.

[0095] Please refer to Figure 2 As shown in Figure (a), when the insulin infusion device 100 is in full working mode, the second touch-sensitive area 102b can display the lock screen graphic element 201, and the user can initiate interactive input to the lock screen graphic element 201 in the second touch-sensitive area 102b, such as clicking on the lock screen graphic element 201, and then the processor can display the unlock graphic element 202 in the second touch-sensitive area 102b.

[0096] Figure 2 Two forms of unlocking graphic elements 202 are illustrated. In one embodiment, the unlocking graphic element 202 may include a first unlocking graphic element 202a, a second unlocking graphic element 202b, and a third unlocking graphic element 202c. Figure 2In the figure (b), after the user clicks the lock screen graphic element 201, the second touch-sensitive area 102b first displays the first unlock graphic element 202a and the second unlock graphic element 202b to prompt the user to slide to unlock. Then, the user can press and hold the first unlock graphic element 202a and slide upward to the second unlock graphic element 202b, after which the second touch-sensitive area 102b will display the third unlock graphic element 202c and unlock the screen of the second touch-sensitive area 102b.

[0097] In one embodiment, the unlocking graphic element 202 may also include a fourth unlocking graphic element 202d and a fifth unlocking graphic element 202d. Figure 2 In the figure (d), after the user clicks the lock screen graphic element 201, the second touch-sensitive area 102b displays the fourth unlock graphic element 202d and the fifth unlock graphic element 202d to prompt the user to long press to unlock. Then, the user can long press the fourth unlock graphic element 202d, and the fifth unlock graphic element 202d will display the unlocking progress of the long press, and the screen lock of the second touch-sensitive area 102b will be released when the long press time of the fourth unlock graphic element 202d reaches the time threshold.

[0098] In some embodiments, the second touch-sensitive area 102b may also display prompt information for unlocking the screen of the second touch-sensitive area 102b. For example, after unlocking the screen of the second touch-sensitive area 102b, “Unlock successful” is displayed in the second touch-sensitive area 102b.

[0099] Understandably, Figure 2 Only some optional unlocking methods are illustrated, and the present embodiment is not limited thereto.

[0100] In the above embodiment, during the operation of the full working mode, the screen lock of the second touch-sensitive area 102b can be efficiently unlocked according to the user's interactive input to the lock screen graphic element 201 displayed in the second touch-sensitive area 102b. In addition, it is necessary to switch to the full working mode through the first touch-sensitive area 102a before unlocking, which can also prevent accidental touches to a certain extent, further improving the safety of the use of the insulin infusion device 100.

[0101] In an exemplary embodiment, optionally, when the insulin infusion device 100 is in the full working mode, the processor is configured to unlock the screen of the second touch-sensitive area 102b according to the user's interactive input to the password input graphic element in the second touch-sensitive area 102b.

[0102] For example, when the insulin infusion device 100 is in low power mode, the user can press the first touch-sensitive area 102a to switch the insulin infusion device 100 from low power mode to full working mode, and the second touch-sensitive area 102b lights up the screen and displays the password input graphic element, and the user can initiate interactive input to the password input graphic element, such as inputting a corresponding numeric password, gesture password, pattern password or mixed password in the password input graphic element, so that the processor can unlock the screen of the second touch-sensitive area 102b. This embodiment does not limit the form of the password input graphic element.

[0103] In the above embodiment, since the insulin infusion device 100 is in full working mode, the screen lock of the second touch-sensitive area 102b can be released safely and efficiently according to the user's interactive input to the password input graphic element in the second touch-sensitive area 102b.

[0104] In one embodiment, after the screen lock of the second touch-sensitive area 102b is released, the second touch-sensitive area 102b can display a fixed interface, such as the main interface, or can display the interface that was on before the screen was turned off last time.

[0105] Figure 3 FIG. 1 is a schematic diagram of a paging mark in an embodiment, such as Figure 3 As shown, in an exemplary embodiment, optionally, after the screen lock of the second touch-sensitive area 102b is released, the processor is used to display the paging mark 301 in the second touch-sensitive area 102b, for example, the paging mark 301 can be displayed at the bottom of the second touch-sensitive area 102b.

[0106] The paging mark 301 is used to indicate the order of the interface currently displayed in the second touch-sensitive area 102b in the interface set. The interface set includes at least one interface that may be displayed in the second touch-sensitive area 102b. During the full working mode, the second touch-sensitive area 102b is used to display the interface set.

[0107] Please refer to Figure 3 In Figure (a), take the interface set including the negative one screen, the main interface and two function menu interfaces (the function menu interface can also be referred to as menu page), and the order of the above four interfaces is first, second, third and fourth as an example. Assuming that the interface currently displayed in the second touch-sensitive area 102b is the main interface, the paging mark 301a can indicate the order of the main interface in the interface set. It can be seen that the order of the main interface in the interface set is second.

[0108] Further, the processor is further configured to switch each interface in the interface set according to the user's interactive input to the second touch-sensitive area 102b along a preset direction. Assuming that the preset direction is left, it means switching to the left interface in the interface set, and the preset direction is right, it means switching to the left interface in the interface set. Continuing with the above example, please refer to Figure 3 In the figure (b), if the interface currently displayed in the second touch-sensitive area 102b is the main interface, the user can slide rightward in the second touch-sensitive area 102b to switch the interface currently displayed in the second touch-sensitive area 102b from the main interface to the first function menu interface. Similarly, the paging mark 301b can indicate the order of the first function menu interface in the interface set, and it can be seen that the order of the first function menu interface in the interface set is the third.

[0109] In the above embodiment, after the screen lock of the second touch-sensitive area 102b is released, a paging mark can be displayed at the bottom of the second touch-sensitive area 102b. In this way, the user can know the order of the interface currently displayed in the second touch-sensitive area 102b in the interface set through the paging mark, so that the user can initiate interactive input to the second touch-sensitive area 102b along a preset direction, and then quickly switch the interfaces in the interface set, thereby improving the user experience.

[0110] In an exemplary embodiment, optionally, the interface set corresponding to the second touch-sensitive area 102b includes a function menu interface. The function menu interface can refer to Figure 3 Figure (b) in the figure, such as Figure 3 As shown in FIG. 2( b ), the function menu interface includes a stop infusion icon 302 .

[0111] The stop infusion icon 302 is used to trigger the stop infusion mode, that is, to control the insulin infusion device 100 to stop infusion, during which the driving mechanism cannot move. The processor is used to control the second touch-sensitive area 102b to display a stop injection confirmation interface according to the user's gesture input to the stop infusion icon 302, and control the insulin infusion device 100 to end the infusion according to the user's confirmation interaction input to the stop injection confirmation interface.

[0112] Optionally, the processor is used to make the drive mechanism enter a prohibited motion state according to the user's confirmation interaction input on the stop injection confirmation interface. The prohibited motion state refers to a state in which the drive mechanism cannot move.

[0113] Figure 4FIG. 1 is a schematic diagram of a stop and resume infusion confirmation interface in an embodiment. For example, when the user wants to control the insulin infusion device 100 to stop infusion, the user can click the stop infusion icon 302 in the function menu interface. After that, the processor can respond to the user's gesture input to the stop infusion icon 302 and display the following on the second touch-sensitive area 102b: Figure 4 The stop injection confirmation interface shown in FIG. (a) in FIG. 1 is provided for the user to make a second confirmation. If the user still wants to control the insulin infusion device 100 to stop infusion, the user can click the check mark icon in the stop injection confirmation interface to initiate a confirmation interaction input, and then the processor can control the insulin infusion device 100 to stop infusion according to the confirmation interaction input.

[0114] In some embodiments, when the insulin infusion device 100 is in the stop infusion mode, that is, when the insulin infusion device 100 is controlled to stop infusion, the processor is further used to display the resume injection confirmation interface in the second touch-sensitive area 102b according to the user's gesture input to the stop infusion icon 302, and resume the infusion function of the insulin infusion device 100 according to the user's confirmation interaction input to the resume injection confirmation interface. Further optionally, the processor is used to enable the drive mechanism to enter a movable state according to the user's confirmation interaction input to the resume injection confirmation interface. The movable state refers to a state in which the drive mechanism can move.

[0115] The recovery injection confirmation interface can be referenced Figure 4 As shown in FIG. 5( b ), the process of restoring the infusion function of the insulin infusion device 100 is similar to the process of controlling the insulin infusion device 100 to end the infusion, and will not be described in detail here.

[0116] In the above embodiment, since the interface set includes a function menu interface, and the function menu interface includes a stop infusion icon 302, and the processor can display a stop injection confirmation interface in the second touch-sensitive area 102b according to the user's gesture input to the stop infusion icon 302, and according to the user's confirmation interaction input to the stop injection confirmation interface, controlling the insulin infusion device 100 to end the infusion requires a second confirmation, so that the insulin infusion device 100 can be efficiently and safely controlled to stop the infusion.

[0117] In an exemplary embodiment, please continue to refer to Figure 3 In FIG. (b), optionally, the function menu interface includes a large-dose infusion icon 303. The large-dose infusion icon 303 is used to set a large-dose infusion mode, that is, to perform a large-dose infusion setting.

[0118] The processor is used to start the bolus infusion setting according to the user's gesture input to the bolus infusion icon 303, control the second touch-sensitive area 102b to display the integer digit setting interface of the bolus infusion parameter, and determine the integer digit of the bolus infusion parameter according to the user's sliding selection interactive input of the parameter displayed in the integer digit setting interface, and control the second touch-sensitive area 102b to display the decimal digit setting interface of the bolus infusion parameter, and determine the decimal digit of the bolus infusion parameter according to the user's sliding selection interactive input of the parameter displayed in the decimal digit setting interface.

[0119] In this embodiment, the bolus infusion setting is used to determine the bolus infusion parameters of the bolus infusion mode, and the bolus infusion parameters may include the bolus infusion type and infusion amount. The bolus infusion type may be at least one of conventional bolus infusion, square wave bolus infusion, and dual wave bolus infusion. Further optionally, when the infusion type is square wave bolus infusion or dual wave bolus infusion, the bolus infusion parameters may also include the infusion duration.

[0120] Figure 5 FIG. 4 is a schematic diagram of a large dose infusion setting in one embodiment. Figure 5 As shown, when the user wants to infuse a large dose, the user can click the large dose infusion icon 303, so that the processor controls the second touch-sensitive area 102b to display an integer digit setting interface in response to the user's gesture input. The integer digit setting interface is as shown in FIG. Figure 5 As shown in Figure (a) in the figure. The integer digit setting interface can be used to set the integer digit of the infusion amount in the large-dose infusion parameter. The integer digit setting interface includes candidate integer values ​​that can be slid and selected and the currently selected integer value. In this way, the user can initiate a sliding selection interactive input based on the parameters displayed in the integer digit setting interface, such as sliding up and down on the integer digit setting interface, so that the processor can determine the integer digit of the large-dose infusion parameter. Please continue to refer to Figure 5 In Figure (a), the user slides between the candidate integer values ​​29, 30 and 31 and selects 30 as the integer digit, so the integer digit of the infusion amount in the large-dose infusion parameter is set to 30.

[0121] After that, the user can click Figure 5 The right arrow icon below the middle (a) figure is used to initiate a gesture input to the integer setting interface of the large dose infusion parameter, and then the processor controls the second touch-sensitive area 102b to display the decimal setting interface of the large dose infusion parameter. The decimal setting interface is as shown in FIG. Figure 5As shown in Figure (b) in the figure. The decimal place setting interface is used to set the decimal place of the infusion amount in the large-dose infusion parameter. The decimal place setting interface includes candidate decimal values ​​that can be slid and selected and the currently selected decimal value. In this way, the user can initiate a sliding selection interactive input based on the parameters displayed in the decimal place setting interface, such as sliding up and down on the decimal place setting interface, so that the processor can determine the decimal place of the large-dose infusion parameter. Please continue to refer to Figure 5 In Figure (b), the user slides between the candidate integer values ​​975, 000, and 025 and selects 000 as the decimal place. Therefore, the decimal place of the infusion amount in the large-dose infusion parameter is set to 000.

[0122] Finally, the user can click Figure 5 The right arrow icon below the middle (b) figure, the second touch-sensitive area 102b can display the following Figure 5 In the confirmation interface shown in Figure (c), the user clicks Figure 5 Click the check mark icon at the bottom of Figure (c) to initiate a confirmation interaction input, and then the processor can receive the confirmation interaction input initiated by the user to complete the large dose infusion setting. Figure 5 As shown, the user sets the bolus parameter to conventional bolus and the infusion volume to 30.000U.

[0123] In some embodiments, during the process of the insulin infusion device 100 performing the bolus infusion setting function, the second touch-sensitive area 102b may also display the infusion type in the bolus infusion parameters. Figure 5 As shown, during the setting process, the currently set infusion type can be displayed through the infusion type mark 501, and the infusion type mark 501 can be distinguished by different waveform shapes, and different waveform shapes represent different infusion types.

[0124] The above example uses the sliding selection interaction input as sliding up and down. In some embodiments, the sliding selection interaction input may also be in other forms, such as sliding left and right.

[0125] In the above embodiment, since the function menu interface includes the large-dose infusion icon 303, the processor can control the second touch-sensitive area 102b to display the integer digit setting interface of the large-dose infusion parameter according to the user's gesture input to the large-dose infusion icon 303, and determine the integer digit of the large-dose infusion parameter according to the user's sliding selection interactive input of the parameter displayed in the integer digit setting interface, and control the second touch-sensitive area 102b to display the decimal digit setting interface of the large-dose infusion parameter, and determine the decimal digit of the large-dose infusion parameter according to the user's sliding selection interactive input of the parameter displayed in the decimal digit setting interface. In this way, the user can efficiently set the large-dose parameter by himself through input such as single click and sliding.

[0126] In an exemplary embodiment, optionally, the processor is used to cancel the integer or decimal place parameters currently input according to the user's horizontal sliding interactive input on the integer setting interface or the decimal place setting interface.

[0127] In this embodiment, the parameters can be modified in a timely manner during the process of setting the large dose infusion parameters. Figure 5 As shown in (a) of FIG. 1 , when the second touch-sensitive area 102b displays the integer digit setting interface, if the user wants to cancel the integer digit currently input, the user can slide leftward in the second touch-sensitive area 102b to initiate a horizontal sliding interaction input, and then the processor responds to the horizontal sliding interaction input to cancel the integer digit parameter currently input. In some embodiments, the processor can return to the previous interface of the integer digit setting interface, such as returning to the function menu interface, after responding to the horizontal sliding interaction input.

[0128] like Figure 5 As shown in Figure (b), when the decimal place setting interface is displayed in the second touch-sensitive area 102b, if the user wants to cancel the decimal places currently input, the user can also slide to the left in the second touch-sensitive area 102b to initiate a horizontal sliding interaction input. Then, the processor responds to the horizontal sliding interaction input to cancel the decimal place parameters currently input.

[0129] In some embodiments, the processor can return to the previous interface of the decimal place setting interface, such as returning to the integer place setting interface, in response to the horizontal sliding interaction input. In this way, if the user wants to modify the integer place again during the process of setting the decimal place, he can also quickly return to the integer place setting interface to implement the parameter modification function.

[0130] In the above embodiment, since the currently input integer or decimal place parameters can be canceled according to the user's horizontal sliding interactive input on the integer setting interface or the decimal setting interface, the user can flexibly modify the parameters through the second touch-sensitive area 102b to improve the user experience.

[0131] In an exemplary embodiment, the function menu interface optionally includes a quick high-dose setting icon. The processor is configured to control the second touch-sensitive area 102b to display the quick high-dose setting interface according to the user's gesture input to the quick high-dose setting icon, and to turn on or off the quick high-dose function according to the user's confirmation interaction input to the quick high-dose setting interface.

[0132] In this embodiment, the quick high-dose setting icon may also be referred to as a quick switch setting icon. After the user clicks the quick high-dose setting icon (not shown in the figure), the second touch-sensitive area 102b may display a quick high-dose setting interface (also referred to as a quick switch setting interface). The quick high-dose setting interface includes a quick high-dose switching icon (also referred to as a quick switch switching icon). When the quick high-dose switching icon is in the off state, if the user initiates a confirmation interaction operation, such as clicking the quick high-dose switching icon, the processor will switch the quick high-dose switching icon from the off state to the on state to turn on the quick high-dose function. When the quick high-dose switching icon is in the on state, if the user initiates a confirmation interaction operation, such as clicking the quick high-dose switching icon, the processor will switch the quick high-dose switching icon from the on state to the off state to turn off the quick high-dose function.

[0133] The quick bolus function is a shortcut that the user can preset to quickly enter the bolus infusion setting function of the insulin infusion device 100. For example, the user can enter the integer digit setting interface of the bolus infusion parameter by long pressing the screen, without having to switch to the function menu interface first, and then enter the integer digit setting interface through the bolus infusion icon 303 in the function menu interface.

[0134] In the above embodiment, since the function menu interface includes a quick high-dose setting icon, and the processor can display the quick high-dose setting interface in the second touch-sensitive area 102b according to the user's gesture input to the quick high-dose setting icon, the quick high-dose function can be efficiently turned on or off according to the user's confirmation interaction input to the quick high-dose setting interface.

[0135] In an exemplary embodiment, optionally, when the quick bolus function is turned on in the insulin infusion device 100 and the bolus infusion is not started, the processor is used to control the second touch-sensitive area 102b to display an integer digit setting interface for the bolus infusion parameter according to the user's pressing input operation on the first touch-sensitive area 102a, and determine the integer digit of the bolus infusion parameter according to the user's sliding selection interactive input of the parameter displayed in the integer digit setting interface, and control the second touch-sensitive area 102b to display a decimal digit setting interface for the bolus infusion parameter, and determine the decimal digit of the bolus infusion parameter according to the user's sliding selection interactive input of the parameter displayed in the decimal digit setting interface.

[0136] In this embodiment, when the insulin infusion device 100 turns on the quick large dose function and does not start the large dose infusion, it means that the user has turned on the quick large dose function, and the insulin infusion device 100 does not perform other large dose infusions. In this case, the user can press and hold the first touch-sensitive area 102a for a preset time to initiate a press input operation on the first touch-sensitive area 102a, and then the processor receives the press input operation and directly jumps to the integer digit setting interface to complete the large dose infusion setting function. The process of completing the large dose infusion setting function can refer to the above embodiments and Figure 5 , I will not go into details here.

[0137] In the above, the pressing input operation is taken as a long press for a preset duration as an example. In some embodiments, the pressing input operation may also be a pressing force reaching a preset force threshold, and the present embodiment is not limited thereto.

[0138] It should be noted that when the insulin infusion device 100 turns on the quick large dose function and does not start large dose infusion, even if the insulin infusion device 100 enters screen lock or screen off, the user can quickly enter the integer digit setting interface by pressing the first touch-sensitive area 102a.

[0139] When the insulin infusion device 100 turns on the quick bolus function but has already started bolus infusion, the user cannot jump to the integer digit setting interface even if they press the first touch-sensitive area 102a. Similarly, when the insulin infusion device 100 turns off the quick bolus function, the user cannot jump to the integer digit setting interface even if they press the first touch-sensitive area 102a.

[0140] In the above embodiment, when the quick bolus function is turned on and the bolus infusion is not started in the insulin infusion device 100, the second touch-sensitive area 102b can be controlled to display the integer digit setting interface of the bolus infusion parameter according to the user's pressing input operation on the first touch-sensitive area 102a, and the integer digit of the bolus infusion parameter is determined according to the user's sliding selection interactive input of the parameter displayed in the integer digit setting interface, and the second touch-sensitive area 102b is controlled to display the decimal digit setting interface of the bolus infusion parameter, and the decimal digit of the bolus infusion parameter is determined according to the user's sliding selection interactive input of the parameter displayed in the decimal digit setting interface. In this way, the user does not need to go through the steps of unlocking, entering the function menu page, finding the bolus infusion icon 303, and then clicking the bolus infusion icon 303. The user only needs to initiate a pressing input operation on the first touch-sensitive area 102a to quickly set the bolus parameter.

[0141] In an exemplary embodiment, please continue to refer to Figure 3In (b) of FIG. 1 , optionally, the function menu interface includes a basal rate infusion icon 304. The basal rate infusion icon 304 is used to set the basal rate infusion mode, that is, to perform basal rate infusion settings. The basal rate infusion settings are used to determine the basal rate infusion parameters of the basal rate infusion mode. The basal rate infusion parameters include the basal rate infusion type and infusion volume. The basal rate infusion type may include a standard basal rate infusion and / or a temporary basal rate infusion.

[0142] Figure 6 FIG. 4 is a schematic diagram of editing the basic rate in one embodiment. Figure 6 As shown, the processor is used to start the basal rate infusion setting according to the user's interactive input to the basal rate infusion icon 304, and control the second touch-sensitive area 102b to display the basal rate scheme setting interface and the editing graphic element. The editing graphic element is used to receive the user's interactive input to set the basal rate infusion scheme.

[0143] In one embodiment, optionally, the processor is used to control the second touch-sensitive area 102b to display the standard basal rate infusion icon 601 based on the user's interactive input to the basal rate infusion icon 304, and to control the second touch-sensitive area 102b to display the basal rate scheme setting interface and editing graphic elements based on the user's interactive input to the standard basal rate infusion icon 601.

[0144] For example, Figure 6 As shown in FIG. 10( a), after the user clicks the basal rate infusion icon 304, the processor may display the standard basal rate infusion icon 601 in the second touch-sensitive area 102b, and after the user clicks the standard basal rate infusion icon 601, the processor may display the standard basal rate infusion icon 601 in the second touch-sensitive area 102b. Figure 6 In some embodiments, after the user clicks the basal rate infusion icon 304, the processor may also directly display the following information in the second touch-sensitive area 102b: Figure 6 Figure (b) shows the basic rate scheme setting interface and editing graphic components.

[0145] The standard basal rate infusion icon 601 is used to set the infusion parameters of the standard basal rate, and the temporary basal rate infusion icon 602 is used to set the infusion parameters of the temporary basal rate. The standard basal rate (also called the conventional basal rate) can be used to meet the metabolic needs of the daily period, while the temporary basal rate can be used to maintain the metabolic needs of the temporary period.

[0146] Exemplarily, the basal rate scheme setting interface includes a current basal rate scheme 603, which may be a standard basal rate scheme currently displayed in the second touch-sensitive area 102b. Figure 6As shown in FIG. 5( b ), the second touch-sensitive area 102 b displays a basal rate plan B1 , which indicates that a standard basal rate is 24 U / day, that is, 24 U of insulin needs to be infused every day.

[0147] It is understandable that a plurality of standard basal rate schemes may be preset in the processor, and of course, the user may also add or modify the standard basal rate scheme. Therefore, the user may slide up and down based on the second touch-sensitive area 102b to initiate a sliding input, and then the processor may switch the current basal rate scheme 603 displayed in the second touch-sensitive area 102b according to the sliding input. For example, the user may switch between basal rate scheme B1, basal rate scheme B2, basal rate scheme B3, and basal rate scheme B4 by sliding up and down.

[0148] The editing graphic element may include an editing graphic element 604. After the user selects the current basic rate plan 603, the user may initiate an interactive input to the editing graphic element 604, such as clicking the editing graphic element 604 to enter the basic rate plan setting interface of the current basic rate plan 603. Figure 6 For example, by clicking the edit graphic element 604, the processor will enter the basic rate plan setting interface of the basic rate plan B1.

[0149] The basic rate plan setting interface can be used to set the current basic rate 603, for example, to edit the basic rate size, basic rate period and other parameters of the current basic rate plan 603 selected by the user.

[0150] In one embodiment, the second touch-sensitive area 102b may further display a start-up graphic element 605, so that the processor may start the current basal rate scheme 603 according to the current basal rate scheme 603 selected by the user and according to the user's interactive input to the start-up graphic element 605. Figure 6 For example, after the user selects the basal rate plan B1, he clicks the start graphic element 605, and the insulin infusion device 100 will start the basal rate plan B1, that is, the basal rate plan B1 will be infused.

[0151] In the above embodiment, the function menu interface includes a basal rate infusion icon 304. The processor can start the basal rate infusion setting according to the user's interactive input to the basal rate infusion icon 304, and control the second touch-sensitive area 102b to display the basal rate scheme setting interface and the editing graphic element. Since the editing graphic element is used to receive the user's interactive input to set the basal rate infusion scheme, the user can also make the basal rate infusion setting based on the second touch-sensitive area 102b.

[0152] Figure 7FIG. 1 is a schematic diagram of editing a basic rate in an embodiment. In an exemplary embodiment, optionally, the basic rate scheme setting interface includes a basic rate period editing interface. The basic rate period editing interface can be as follows: Figure 7 As shown in Figure (a).

[0153] The processor is used to control the second touch-sensitive area 102b to display the time period setting interface corresponding to the time period to be modified 701 according to the user's selection input of the time period to be modified 701 in the basic rate time period editing interface, and to modify the start time and / or end time of the time period to be modified 701 according to the user's sliding selection interactive input on the time period setting interface.

[0154] Please combine Figure 6 and Figure 7 After the user clicks the edit graphic element 604, the second touch-sensitive area 102b displays the following Figure 7 The basic rate period editing interface shown in (a) is used to edit the period of the current basic rate plan 603, for example, to edit the period of the basic rate plan B1.

[0155] The user can select the time period to be modified in the basic rate time period editing interface, for example, select the time period 701 to be modified "00:00-24:00", and then click Figure 7 (a) The edit icon in the lower middle part is clicked to initiate the selection input of the time period to be modified 701, and the time period setting interface corresponding to the time period to be modified 701 is displayed in the second touch-sensitive area 102b. Figure 7 Figure (b) in the Figure 7 As shown in Figure (e).

[0156] The time period setting interface may include a single candidate time point, and the user may select the required start time and / or end time by sliding in the time period setting interface corresponding to the time period to be modified 701. Figure 7 For example, the user slides in the second touch-sensitive area 102b to initiate a sliding selection interactive input on the time period setting interface, thereby causing the processor to modify the end time of the time period to be modified 701 to "01:30". After that, two time periods to be modified 701, "00:00-01:30" and "01:30-24:00", can be generated. Figure 7 As shown in Figure (e) in the figure. Through the above operation, the user can achieve the purpose of segmenting the standard basic rate, that is, different basic rates can be set for different time periods.

[0157] In one embodiment, the time period setting interface corresponding to the time period to be modified 701 can also set the basic rate corresponding to the time period to be modified 701. Optionally, according to the user's sliding selection interactive input on the time period setting interface, after modifying the end time of the time period to be modified 701, the processor can display the integer digit setting interface of the basic rate in the second touch-sensitive area 102b. The integer digit setting interface of the basic rate is as shown in FIG. Figure 7 As shown in FIG. 10c, according to the user's sliding selection interactive input of the parameter displayed in the integer digit setting interface, the integer digit of the basic rate corresponding to the time period to be modified 701 is determined, and according to the user's gesture input on the integer digit setting interface, the decimal digit setting interface of the basic rate is displayed in the second touch-sensitive area 102b. The decimal digit setting interface of the basic rate is as shown in FIG. Figure 7 As shown in Figure (d) in the figure, the decimal places of the basal rate corresponding to the time period to be modified 701 are determined according to the user's sliding selection interactive input of the parameters displayed in the decimal place setting interface, and the basal rate segmented setting function of the insulin infusion device 100 is completed according to the user's confirmation interactive input. Figure 7 The integer and decimal places settings interface in Figure 5 The principle is similar and will not be repeated here.

[0158] In the above embodiment, since the basic rate plan setting interface includes a basic rate time period editing interface, the processor can display the time period setting interface corresponding to the time period to be modified 701 in the second touch-sensitive area 102b according to the user's selection input of the time period to be modified 701 in the basic rate time period editing interface, and modify the end time of the time period to be modified 701 according to the user's sliding selection interactive input on the time period setting interface. In this way, the function of segmenting the basic rate can be realized, thereby setting different basic rates for different time periods.

[0159] In an exemplary embodiment, optionally, please continue to refer to Figure 3 The reset filling icon 305 is used to trigger the execution of the reset filling mode, that is, to control the insulin infusion device 100 to perform reset filling.

[0160] In an exemplary embodiment, please continue to refer to Fig. 1, optionally, the shell edge of the shell 101 is arc-shaped. The distance d between the edge of the second touch-sensitive area 102b and the shell edge of the shell 101 is greater than or equal to 1.5 mm.

[0161] In this embodiment, the product form included in the insulin infusion device 100 can have a larger second touch-sensitive area 102b, so as to receive the user's touch input to the second touch-sensitive area 102b. For example, the distance between the edge of the second touch-sensitive area 102b and the shell edge of the shell 101 is set to be greater than or equal to 1.5 mm, where 1.5 mm can be the width of the black border surrounding the second touch-sensitive area 102b, so that a display area with a narrow border can be formed. In addition, there is a certain distance between the edge of the shell and the edge of the second touch-sensitive area 102b, so that the user will not easily touch the second touch-sensitive area 102b by mistake when holding the shell 101.

[0162] Figure 8 is a schematic diagram of yet another insulin infusion device in one embodiment, Fig. 9 FIG. 1 is a block diagram of an insulin infusion device in one embodiment. In an exemplary embodiment, Figure 8 and Fig. 9 As shown, optionally, the shell 101 includes a first cavity 801 and a second cavity 802 inside the shell 101 .

[0163] The first cavity 801 is used to place a liquid reservoir 901 and a driving mechanism 902. The liquid reservoir 901 (also referred to as a drug reservoir) may be a container for storing insulin. The driving mechanism 902 is coupled to the processor 904, and the driving mechanism 902 is used to push the liquid in the liquid reservoir 901 to achieve the infusion function of the insulin infusion device 100. The second cavity 802 is used to place a power source 903. The power source 903 may include, but is not limited to, a lithium battery.

[0164] During the full working mode operation, the processor 904 turns on the power supply 903 so that the power supply 903 provides power to the driving mechanism 902 and the touch screen 102. During the low power mode operation, the processor 904 interrupts the power supply 903 to stop providing power to the touch screen 102.

[0165] In the above embodiment, since the housing 101 includes a first cavity 801 and a second cavity 802, and the first cavity 801 is used to place the liquid reservoir 901 and the driving mechanism 902, the driving mechanism 902 is coupled to the processor 904, and the second cavity 802 is used to place the power supply 903, the structure of the insulin infusion device 100 is relatively compact, and the volume of the insulin infusion device 100 is not large, which is convenient for users to carry or hold. In addition, since the power supply 903 can be turned on to provide power to the driving mechanism 902 and the touch screen 102 during the full working mode, and the power supply 903 can be interrupted to stop providing power to the touch screen 102 during the low power mode, the use time of the insulin infusion device 100 can also be extended.

[0166] In an exemplary embodiment, optionally, the area ratio of the first touch-sensitive area 102a to the second touch-sensitive area 102b is 1:1-1:10.

[0167] Among them, when the area ratio of the first touch-sensitive area 102a to the second touch-sensitive area 102b is 1:1, the second touch-sensitive area 102b displays a function icon to provide the user with a larger touch operation space, which is more suitable for use by the elderly. The insulin infusion device 100 can be remotely controlled using a mobile terminal installed with an infusion control mobile application (Application, app). The user can operate on the infusion control mobile application of the mobile terminal. The insulin infusion device 100 and the mobile terminal receive the infusion control signal sent by the mobile terminal APP through wireless communication and perform corresponding infusion. This embodiment is not limited here.

[0168] It is understandable that, when the area ratio of the second touch-sensitive area 102b is higher, the second touch-sensitive area 102b can display more content, which is also conducive to the user controlling the insulin infusion device 100 based on the content displayed in the second touch-sensitive area 102b.

[0169] In an exemplary embodiment, optionally, the width-to-length ratio of the second touch-sensitive area 102b is 1:1-1:8 along the center line of the housing 101. In this way, the second touch-sensitive area 102b is conducive to layout and display of function icons, and is convenient for single finger operation, and the user experience is more friendly, for example, Figure 3 shown.

[0170] Further optionally, the second touch-sensitive area 102b may display a plurality of function icons side by side, for example, display two or more function icons side by side, which not only enriches the display but also facilitates user selection and input.

[0171] The width-to-length ratio refers to the ratio between the width and length of the second touch sensitive area 102b. Referring to FIG1 , the length of the second touch sensitive area 102b along the center line of the housing 101 is greater than or equal to the length perpendicular to the center line.

[0172] In the above embodiment, if the area ratio of the first touch-sensitive area 102a to the second touch-sensitive area 102b is 1:1-1:10, the area of ​​the first touch-sensitive area 102a is small and will not be easily touched by mistake, while the area of ​​the second touch-sensitive area 102b is large, which is convenient for displaying information based on the second touch-sensitive area 102b. If the width-to-length ratio of the second touch-sensitive area 102b along the center line of the housing 101 is 1:1-1:8, it means that the second touch-sensitive area 102b is a relatively narrow and long area, which is convenient for display and user interaction, thereby improving the user experience.

[0173] In an exemplary embodiment, please continue to refer to FIG1 , optionally, the first touch sensitive area 102a and the second touch sensitive area 102b are sequentially arranged side by side along the center line direction of the housing 101. The center line direction of the housing 101 can refer to the dotted line in FIG1 .

[0174] In an exemplary embodiment, optionally, the first touch-sensitive area 102a includes an input mark. The input mark is used to guide the user to implement the first interactive input or the second interactive input. Exemplarily, the input mark can be a white circle in the first touch-sensitive area 102a in FIG. 1. Further optionally, the input mark can be an integrated structure with the touch screen 102, and the input mark can be printed on the touch screen 102.

[0175] The overall appearance of the insulin infusion device 100 provided in the above embodiment is a long strip, which is convenient for the user to hold in the palm of his hand. Along the midline direction of the shell 101, the first touch-sensitive area 102a and the second touch-sensitive area 102b are arranged side by side in sequence, and the center of the first touch-sensitive area 102a includes an input mark. Therefore, the user can quickly get started with the insulin infusion device 100, which is convenient for the user to interact.

[0176] In an exemplary embodiment, optionally, the first interactive input includes a user continuously pressing an input identifier; the processor 904 is further configured to monitor the duration of pressing the input identifier and switch the low power mode to the full working mode according to the duration.

[0177] In this embodiment, the user can continuously press the input mark in the first touch-sensitive area 102a to initiate the first interactive input. Furthermore, the processor 904 can monitor the duration of pressing the input mark, and when the duration of pressing the input mark is greater than the preset pressing duration, determine that the first interactive input is valid, and switch the low power mode to the full working mode in response to the first interactive input.

[0178] Exemplarily, when the insulin infusion device 100 is in low power mode, the user can press the input mark in the first touch-sensitive area 102a. When the user presses the input mark for a time longer than a preset pressing time, the processor 904 switches the insulin infusion device 100 from low power mode to full working mode.

[0179] The above mainly introduces the structure and interaction process of the insulin infusion device 100, and the following will introduce the control process of the insulin infusion device 100.

[0180] In an exemplary embodiment, the drive mechanism 902 optionally includes a motor 902a. The processor 904 is further configured to determine a target number of rotation coils of the motor 902a according to the parameters of the bolus infusion setting and / or the parameters of the basal rate setting, and control the motor 902a to perform forward motion according to the target number of rotation coils to perform insulin infusion.

[0181] In this embodiment, the parameter of the bolus infusion setting is also the above-mentioned bolus infusion parameter. The parameter of the basal rate setting is also the above-mentioned basal rate infusion parameter. The processor 904 can store a preset correspondence between different infusion parameters and the number of movement coils of the motor 902a. In this way, when infusion is required, the processor 904 can determine the target number of movement coils of the motor 902a based on the correspondence and the parameter of the bolus infusion setting and / or the parameter of the basal rate setting.

[0182] The forward motion of the motor 902a is a motion that enables the insulin infusion device 100 to perform an infusion operation. During the forward motion of the motor 902a, the motor 902a drives the push mechanism of the reservoir 901 in the insulin infusion device 100 to move forward. Further, during the forward motion of the push mechanism, the push mechanism pushes out the insulin in the reservoir 901 to control the insulin infusion device 100 to perform an infusion, that is, perform insulin infusion. The push mechanism includes but is not limited to a push rod.

[0183] Further optionally, the preset correspondence may include a first correspondence between different infusion parameters U and the advance distance S of the push mechanism, and a second correspondence between different advance distances S and the number of moving coils X of the motor 902a that rotates forward. Taking the push mechanism including the push rod as an example, in order to accurately infuse a certain amount of insulin in a single insulin infusion device 100, the infusion parameter U can be converted into the linear advance distance S of the push rod according to the size of the reservoir 901, and the advance distance S can be converted into the number of moving coils X of the motor 902a that rotates forward by calculating the lead of the motor 902a screw. In this way, as long as the number of moving coils X of the motor 902a can be accurately controlled during a single infusion, the single infusion amount can be accurately controlled.

[0184] Further optionally, the processor 904 may send the parameters of the bolus infusion setting and / or the parameters of the basal rate setting to the control integrated circuit (IC) of the motor 902a through the serial port, and the driver IC of the motor 902a parses the parameters of the bolus infusion setting and / or the parameters of the basal rate setting to determine the target number of motion coils, and then the driver IC of the motor 902a drives the motor 902a to perform forward motion according to the target number of motion coils.

[0185] In the above embodiment, since the driving mechanism 902 includes a motor 902a, and the target number of rotation coils of the motor 902a is determined according to the parameters of the bolus infusion setting and / or the parameters of the basal rate setting, and the motor 902a is controlled to perform forward motion according to the target number of rotation coils, insulin infusion can be performed efficiently and accurately.

[0186] In an exemplary embodiment, optionally, the driving mechanism 902 further includes an encoder 902b, which is connected to the rotating shaft of the motor 902a, and the encoder 902b is also coupled to the processor 904. The processor 904 is further used to obtain the actual number of moving coils of the motor 902a through the encoder 902b, and determine whether the actual number of moving coils is less than the target number of moving coils. If the actual number of moving coils is less than the target number of moving coils, the motor 902a is controlled according to the target number of moving coils based on the PID control strategy until the actual number of moving coils is equal to the target number of moving coils, and then the insulin infusion is terminated.

[0187] In this embodiment, the encoder 902b is used to detect the actual number of moving coils of the motor 902a. The processor 904 can obtain the actual number of moving coils of the motor 902a through the encoder 902b and compare the actual number of moving coils with the target number of moving coils. If the actual number of moving coils is not less than the target number of moving coils, the processor 904 can control the motor 902a to stop rotating to end the insulin infusion.

[0188] If the actual number of moving coils is less than the target number of moving coils, it means that the motor 902a has not yet rotated to the specified target number of moving coils. In this case, the processor 904 will control the motor 902a according to the target number of moving coils based on the PID control strategy until the actual number of moving coils is equal to the target number of moving coils, thereby ending the insulin infusion.

[0189] In one embodiment, the predefined condition includes that the actual number of moving coils is equal to the target number of moving coils. That is, if the actual number of moving coils is equal to the target number of moving coils, it also means that the insulin infusion device 100 has completed the infusion, and the processor 904 can control the insulin infusion device 100 to enter the low power mode.

[0190] In an exemplary embodiment, optionally, if the actual number of moving coils is less than the target number of moving coils, the processor 904 can determine a control parameter within a preset range and control the motor 902a to perform forward motion according to the control parameter until the actual number of moving coils is not less than the target number of moving coils.

[0191] Among them, the control parameter can be a parameter used to adjust the PID control strategy. Exemplarily, the control parameter can be at least one of the current error e(k), the error accumulation Σe(k), the difference between the current error and the previous error (k)-e(k-1), the proportional weight coefficient Kp, the integral weight coefficient Ki and the differential weight coefficient Kd. The preset range can be set according to demand. It should be noted that the preset ranges of different control parameters can be different. For example, the proportional weight coefficient Kp can correspond to the preset range 1, and the integral weight coefficient Ki can correspond to the preset range 2.

[0192] Exemplarily, the processor 904 may obtain an initial value of the control parameter from storage, and continuously iterate the initial value of the control parameter to obtain a control parameter within a preset range.

[0193] After determining that the control parameters are within the preset range, the processor 904 can control the motor 902a to rotate forward according to the control parameters until the actual number of moving coils is not less than the target number of moving coils. For example, the processor 904 can determine the target pulse width modulation (PWM) according to the control parameters, and control the motor 902a to rotate forward according to the target pulse width modulation.

[0194] In an exemplary embodiment, optionally, the processor 904 is further configured to determine a target control value according to the control parameter, determine a target pulse width modulation according to the target control value, and control the motor 902a to perform forward motion according to the target pulse width modulation.

[0195] The processor 904 may calculate the control parameter to obtain the target control value value. The calculation method may include but is not limited to addition, subtraction, multiplication, division, weighting, etc.

[0196] Afterwards, the processor 904 can determine the target pulse width modulation according to the target control value, and control the motor 902a to rotate forward according to the target pulse width modulation. Optionally, the processor 904 can store the correspondence between different control values ​​and different PWMs, so that after determining the target control value, the target pulse width modulation can be determined using the correspondence, and the motor 902a can be controlled to rotate forward according to the target pulse width modulation. In this way, by adjusting the waveform of PWM, the movement of the motor 902a can be adjusted, so that the motor 902a finally rotates to the target number of movement coils.

[0197] In an exemplary embodiment, optionally, the processor 904 is also used to obtain the rotation speed of the motor 902a. If the rotation speed is not greater than a preset speed threshold, the motor 902a is controlled to rotate forward according to the target pulse width modulation. If the rotation speed is greater than the preset speed threshold, the preset pulse width modulation is used as the target pulse width modulation, and the motor 902a is controlled to rotate forward according to the target pulse width modulation.

[0198] The processor 904 may obtain the rotation speed of the motor 902a. Optionally, the processor 904 may determine the rotation speed of the motor 902a through a speed sensor disposed on the motor 902a. The rotation speed of the motor 902a may be the current speed of the motor 902a or the average speed of the motor 902a in a cycle, and the present embodiment is not limited thereto.

[0199] Furthermore, the processor 904 compares the rotation speed with a preset speed threshold to determine whether the rotation of the motor 902a is stable. The preset speed threshold is set according to demand, and it can be the speed when the motor 902a rotates smoothly.

[0200] If the rotation speed is not greater than the preset speed threshold, it means that the motor 902a rotates smoothly, so the processor 904 controls the motor 902a to rotate forward according to the determined target pulse width modulation. If the rotation speed is greater than the preset speed threshold, it means that the motor 902a has exceeded the speed and has the risk of losing control, so the processor 904 will use the preset pulse width modulation as the target pulse width modulation and control the motor 902a to rotate forward according to the target pulse width modulation, that is, the processor 904 will control the motor 902a to rotate forward according to the preset pulse width modulation. The preset pulse width modulation can be a value stored in the processor 904 in advance, which is used to reduce the rotation speed of the motor 902a.

[0201] In the above embodiment, since the rotation speed of the motor 902a can be obtained, and when the rotation speed is not greater than the preset speed threshold, the motor 902a is controlled to rotate forward according to the target pulse width modulation, and when the rotation speed is greater than the preset speed threshold, the preset pulse width modulation is used as the target pulse width modulation, and the motor 902a is controlled to rotate forward according to the target pulse width modulation. In this way, the rotation of the motor 902a can be controlled more smoothly, and the safety of insulin infusion is further improved.

[0202] Fig.10 FIG. 1 is a schematic diagram of an infusion process in an embodiment, Fig.10As shown, the processor 904 first determines the target number of moving coils, and obtains the actual number of moving coils of the motor 902a through the encoder 902b. If the actual number of moving coils is not less than the target number of moving coils, the processor 904 controls the motor 902a to stop rotating, so as to control the insulin infusion device 100 to end the infusion, thereby ending the entire infusion process.

[0203] If the actual number of moving coils is less than the target number of moving coils, the processor 904 determines the control parameter within the preset range, and determines the target control value according to the control parameter, so as to determine the target pulse width modulation according to the target control value. Afterwards, the processor 904 will also obtain the rotation speed of the motor 902a. If the rotation speed is not greater than the preset speed threshold, the motor 902a is controlled to rotate forward according to the target pulse width modulation. If the rotation speed is greater than the preset speed threshold, the preset pulse width modulation is used as the target pulse width modulation, and the motor 902a is controlled to rotate forward according to the target pulse width modulation. It can be understood that after controlling the motor 902a to rotate forward, the motor 902a rotates and periodically returns to the process of obtaining the actual number of moving coils.

[0204] In some embodiments, obtaining the rotation speed of the motor 902a may also occur before calculating the control parameters. If the rotation speed is greater than a preset speed threshold, there is no need to calculate the control parameters, and the motor 902a can be directly controlled to rotate forward according to the preset pulse width modulation.

[0205] In an exemplary embodiment, optionally, the processor 904 is further configured to control the clock of the insulin infusion device 100 to trigger an interruption mechanism according to a preset period, and control the driving mechanism 902 to perform infusion when the interruption mechanism is triggered.

[0206] Among them, the preset cycle is set according to demand, for example, it can be 3 minutes. Taking the insulin infusion device 100 starting an infusion with a basal rate of 1U / h (1 unit per hour) as an example, the processor 904 can be connected to the clock (Real_Time Clock, RTC), and the RTC acts as a timer to generate an interrupt every 3 minutes, that is, trigger the interrupt mechanism to wake up the processor 904. Furthermore, every 3 minutes, the processor 904 will control the drive mechanism 902 to perform an infusion. It can be understood that the above-mentioned timed triggering process is usually used for basal rate infusion, that is, the processor 904 is in the basal rate infusion mode.

[0207] In one embodiment, optionally, the processor 904 may also determine the target number of moving coils of the driving mechanism 902 according to the parameters of the basal rate setting when determining the clock-triggered interruption mechanism. Taking the basal rate setting parameter as 1U / h as an example, the processor 904 may control the clock-triggered interruption mechanism of the insulin infusion device 100 every 3 minutes according to the 1U / h.

[0208] The following takes triggering an interrupt mechanism every 3 minutes as an example, and this embodiment does not limit the interval time of the interrupt mechanism. Exemplarily, the RTC acts as a timer, generates an interrupt every 3 minutes, wakes up the processor 904, and after the processor 904 is awakened, the infusion parameters for every 3 minutes are converted according to 1U / h, and the target number of motion coils corresponding to each interrupt mechanism is determined according to the infusion parameters for every 3 minutes. That is, when it is determined that the RTC triggers the interrupt mechanism, the processor 904 can determine the target number of motion coils corresponding to each interrupt mechanism according to the infusion parameters for every 3 minutes. Further optionally, the processor 904 can send the infusion parameters for every 3 minutes to the control IC of the motor 902a through the serial port, and the driver IC of the drive motor 902a controls the motor 902a to move forward according to the target number of motion coils.

[0209] In the above embodiment, since the clock of the insulin infusion device 100 is controlled to trigger the interruption mechanism according to a preset period, and the driving mechanism 902 is automatically controlled to perform infusion when the interruption mechanism is triggered, the infusion efficiency of the insulin infusion device 100 is improved.

[0210] In an exemplary embodiment, optionally, the processor 904 is also used to obtain the infusion test result of the insulin infusion device 100 during the insulin infusion process, and if the infusion test result is an abnormal result, the insulin infusion is terminated. The infusion test result is used to indicate whether the infusion process is normal. The infusion test result may include a normal result or an abnormal result.

[0211] In an exemplary embodiment, the infusion detection result may be a magnetic field detection result and / or a tube blockage detection result. Optionally, the processor 904 is further configured to determine that the infusion detection result is an abnormal result if at least one of the following conditions exists: (1) the magnetic field strength of the insulin infusion device 100 is greater than a preset magnetic field threshold; (2) the insulin infusion device 100 is about to be or has been blocked.

[0212] The insulin infusion device 100 may include a magnetic field sensor, which is used to monitor the magnetic field strength of the environment where the insulin infusion device 100 is located. The magnetic field sensor may be independently arranged outside the insulin infusion device 100, or may be arranged inside the insulin infusion device 100.

[0213] The processor 904 can be connected to the magnetic field sensor for communication. Then, the processor 904 can determine the magnetic field strength monitored by the magnetic field sensor and determine whether the magnetic field strength is greater than a preset magnetic field threshold.

[0214] The preset magnetic field threshold can be stored in the processor 904 in advance and can be set as required. If the magnetic field strength in which the insulin infusion device 100 is located is greater than the preset magnetic field threshold, it means that the magnetic field strength exceeds the standard and the insulin infusion device 100 will have safety risks in this environment. In this case, the processor 904 will end the insulin infusion, that is, control the motor 902a to stop rotating.

[0215] In this embodiment, the insulin infusion device 100 can also perform tube blockage detection. The tube blockage detection is used to determine whether the insulin infusion device 100 is about to or has been blocked. The tube blockage detection can be implemented in at least one of the following two ways.

[0216] In a first implementation, the insulin infusion device 100 may include a pressure sensor 1203 disposed between the driving mechanism 902 and the bottom of the first cavity 801 , and used to detect the infusion pressure of the push mechanism. The pressure sensor 1203 can communicate with the processor 904 .

[0217] During the infusion process, there is a certain resistance to the advancement of the push mechanism. If there is no tube blockage, the infusion pressure is small, and if there is tube blockage, the infusion pressure is large. Therefore, if the infusion pressure is greater than the preset pressure threshold, it means that the insulin infusion device 100 may have tube blockage, and continuing the infusion is dangerous. Therefore, the processor 904 will end the insulin infusion when the infusion pressure is greater than the preset pressure threshold.

[0218] In a second implementation, the insulin infusion device 100 may include a current detection amplifier 1305 and a measuring resistor 1306, which are connected in series. Optionally, the measuring resistor 1306 is disposed between the driving mechanism 902 and a driver corresponding to the driving mechanism 902. Further optionally, the measuring resistor 1306 may be a precision resistor.

[0219] Among them, the current detection amplifier 1305 is used to detect the current flowing through the measuring resistor 1306. During the infusion process, there is a certain current between the driving mechanism 902 and the driver corresponding to the driving mechanism 902. If there is no tube blockage, the current flowing through the measuring resistor 1306 is small, and if there is a tube blockage, the current flowing through the measuring resistor 1306 is large. Therefore, if the current flowing through the measuring resistor 1306 is greater than the preset current threshold, it means that the insulin infusion device 100 may have a tube blockage. Therefore, the processor 904 determines whether the current flowing through the measuring resistor 1306 is greater than the preset current threshold, and ends the insulin infusion when the current flowing through the measuring resistor 1306 is greater than the preset current threshold.

[0220] In this way, the processor 904 can determine at least one abnormal situation in the above-mentioned infusion process, and then promptly control the insulin infusion device 100 to end the infusion, thereby improving the safety of the user during use.

[0221] In one embodiment, if the infusion test result is an abnormal result, the processor 904 will issue a second alarm message. The form of the second alarm message can refer to the first alarm message, and this embodiment is not limited thereto.

[0222] Fig.11 FIG. 4 is a schematic diagram of another infusion process in one embodiment, as shown in FIG. Fig.11 As shown, in the process of controlling the insulin infusion device 100 to perform insulin infusion, that is, after the infusion starts, the processor 904 obtains the infusion detection result of the infusion device. If the infusion detection result is a normal result, the insulin infusion device 100 is controlled to perform insulin infusion normally. If the infusion detection result is an abnormal result, the processor 904 will control the insulin infusion device 100 to end the insulin infusion and issue a second alarm message. Afterwards, the processor 904 will determine whether the infusion is completed. If the output is not completed, it will return to the step of obtaining the infusion detection result of the infusion device. If the output is completed, the entire process will be terminated. Among them, the processor 904 can determine whether the infusion is completed by whether the driving mechanism 902 is rotated, or it can determine whether the infusion is completed by whether the actual number of moving coils is greater than the target number of moving coils. This embodiment is not limited to this.

[0223] Fig.12 is a schematic diagram of a gasket in one embodiment, Fig.12 A schematic side view of a push injection component in an insulin infusion device 100 is shown. Fig.12 As shown, the insulin infusion device 100 includes a first cavity 801, a driving mechanism 902, a driving mechanism sleeve 1201, a piston 1202, a reservoir 901 and a pressure sensor 1203. The driving mechanism sleeve 1201 includes but is not limited to a motor sleeve.

[0224] In an exemplary embodiment, optionally, the insulin infusion device 100 further includes a gasket 1204. The gasket 1204 is used to transmit the pressure applied to the pressure sensor 1203.

[0225] Please continue to refer to Fig.12 The gasket 1204 may include a gasket 1204a and / or a gasket 1204b. The gasket 1204a is disposed between the pressure sensor 1203 and the inner wall of the first cavity 801. The gasket 1204b is disposed between the pressure sensor 1203 and the driving mechanism 902.

[0226] In the above embodiment, since the insulin infusion device 100 also includes a gasket 1204, and the gasket 1204 is used to transmit the pressure applied to the pressure sensor 1203, thus, by providing the gasket 1204, it is more conducive for the pressure sensor 1203 to obtain the infusion pressure, thereby improving the accuracy of tube blockage detection.

[0227] Fig.13 FIG. 1 is a schematic diagram of yet another insulin infusion device in one embodiment, Fig.13 As shown, in one embodiment, optionally, the insulin infusion device 100 may include a processor 904, a power supply 903, and a control module 1301. The control module 1301 includes a drive controller 1302, a driver 1303, a drive mechanism 902, and a level converter 1304. The drive mechanism 902 includes a motor 902a and an encoder 902b. Among them, the drive controller 1302 is, for example, a control IC of the motor 902a, and the driver 1303 is, for example, a drive IC of the motor 902a.

[0228] The power supply 903 can supply power to the control module 1301 under the control of the processor 904. The control module 1301 is used to control the insulin infusion device 100 to perform infusion, and the power supply of all active components in the control module 1301 can be provided by the power supply 903.

[0229] The drive controller 1302 receives the instructions of the processor 904, and controls the driver 1303 according to the instructions of the processor 904, and then the driver 1303 controls the motor 902a of the drive mechanism 902 to provide the infusion force to rotate forward. The encoder 902b is used to obtain the operating state of the drive mechanism 902, such as obtaining the actual number of moving coils of the drive mechanism 902. The level converter 1304 is used to receive the information obtained by the encoder 902b, and further feed it back to the output to the drive controller 1302 for subsequent control.

[0230] Further optionally, the insulin infusion device 100 may include a current detection amplifier 1305 and a measuring resistor 1306 disposed between the driver 1303 and the motor 902a. The current detection amplifier 1305 is used to detect the current of the measuring resistor 1306 to determine whether the tube is blocked.

[0231] In some embodiments, the insulin infusion device 100 may further include at least one of a clock module, a peripheral module, and other functional modules. The clock module is used to provide the clock required for the insulin infusion device 100 to work, so as to synchronize the operation of each component in the insulin infusion device 100. The peripheral module is used for the user to perform human-computer interaction with the insulin infusion device 100. Other functional modules can be set according to demand, such as a storage interface or a communication interface for the peripheral module. Similarly, other functional modules can also be powered on only when they need to work.

[0232] The processor 904 can communicate with the clock module, the peripheral module or other functional modules. Each module may be controlled by one processor 904, or the processor 904 may include multiple control chips, and the control chips may control different modules respectively.

[0233] In some embodiments, when power-consuming modules such as the control module 1301, touch screen 102 or other functional modules have a low-power working mode and the working power in the low-power mode is low enough, the processor 904 may control these power-consuming modules not by controlling their power on and off, but by controlling them to enter and exit the low-power mode, so as to achieve the purpose of reducing power consumption.

[0234] In an exemplary embodiment, in order to save electric energy, optionally, the processor 904 is also used to turn on the power supply corresponding to the driving mechanism 902 in the insulin infusion device 100 when controlling the insulin infusion device 100 to perform insulin infusion, and turn off the power supply when the insulin infusion is ended.

[0235] The power supply corresponding to the driving mechanism 902 in the insulin infusion device 100 may be the above-mentioned Fig.13 The power supply 903 in the control module 1301 can be turned off to stop the control module 1301 from working.

[0236] Optionally, the processor 904 may control the insulin infusion device 100 to perform insulin infusion and turn on the power supply corresponding to the driving mechanism 902 in the insulin infusion device 100 upon receiving an infusion confirmation initiated by the user or triggering an interruption mechanism according to a preset period.

[0237] Optionally, the processor 904 can determine whether the infusion is completed by whether the driving mechanism 902 is rotating, or by whether the actual number of moving coils is greater than the target number of moving coils, and then end the insulin infusion and turn off the power supply corresponding to the driving mechanism 902 in the insulin infusion device 100.

[0238] In the above embodiment, when the insulin infusion device 100 is controlled to perform insulin infusion, the power supply corresponding to the driving mechanism 902 in the insulin infusion device 100 is turned on, and when the insulin infusion is finished, the power supply is turned off. In this way, the driving mechanism 902 consumes energy only during the infusion period, and no energy is consumed at other times, thereby saving system power consumption and improving the battery life of the insulin infusion device 100.

[0239] In an exemplary embodiment, optionally, the processor 904 is also used to obtain the number of return movement coils of the insulin infusion device 100 after the power supply is turned off, and display an infusion prompt in the second touch-sensitive area 102b according to the number of return movement coils and the target number of movement coils of the insulin infusion device 100.

[0240] In this embodiment, after the processor 904 turns off the power supply corresponding to the driving mechanism 902 in the insulin infusion device 100, the number of return movement coils of the insulin infusion device 100 can be obtained through the encoder 902b. The number of return movement coils of the insulin infusion device 100 represents the total number of rotating coils of the driving mechanism 902 during the process of controlling the insulin infusion device 100 to perform insulin infusion.

[0241] Afterwards, the processor 904 can display an infusion prompt in the second touch-sensitive area 102b according to the number of return movement coils and the target number of movement coils of the insulin infusion device 100. For example, the processor 904 can display "Infusion successful" in the second touch-sensitive area 102b when the number of return movement coils is equal to the target number of movement coils, and display "Infusion failed" in the second touch-sensitive area 102b when the number of return movement coils is not equal to the target number of movement coils. For another example, the processor 904 can display "Infusion successful" in the second touch-sensitive area 102b when the absolute value of the difference between the number of return movement coils and the target number of movement coils is less than a preset difference threshold value △, and vice versa, display "Infusion failed" in the second touch-sensitive area 102b.

[0242] Fig.14 FIG. 4 is a schematic diagram of another infusion process in one embodiment, as shown in FIG. Fig.14As shown, the processor 904 controls the insulin infusion device 100 to perform insulin infusion, that is, when the infusion starts, the power supply corresponding to the driving mechanism 902 in the insulin infusion device 100 is turned on, for example, the power supply 903 normally supplies power to the control module 1301. After that, the processor 904 determines the target number of moving coils, and controls the driving mechanism 902 of the insulin infusion device 100 to perform forward motion according to the target number of moving coils, so as to control the insulin infusion device 100 to perform infusion. If the infusion is not completed, the step of controlling the driving mechanism 902 of the insulin infusion device 100 to perform forward motion according to the target number of moving coils is returned to execute. If the infusion is completed, the power supply corresponding to the driving mechanism 902 in the insulin infusion device 100 is turned off, for example, the control module 1301 is powered off.

[0243] Furthermore, after turning off the power supply corresponding to the driving mechanism 902 in the insulin infusion device 100, the processor 904 will also obtain the number of return movement coils of the insulin infusion device 100, and determine whether the absolute value of the difference between the number of return movement coils and the target number of lines is within the allowable error Δ; if it is within the allowable error Δ, the infusion is terminated normally; if it is not within the allowable error Δ, an infusion prompt is issued, such as the prompt "infusion failed", to remind the user to check whether the device has a fault, so as to avoid physical damage to the user due to inaccurate infusion.

[0244] In the above embodiment, after the power supply is turned off, the number of return movement coils of the insulin infusion device 100 is obtained, and the infusion prompt is displayed in the second touch-sensitive area 102b according to the number of return movement coils and the target number of movement coils of the insulin infusion device 100. Therefore, the user can be reminded of the infusion status in time, thereby improving the user experience.

[0245] In an exemplary embodiment, optionally, the first interaction input includes touch input and / or force input, and the second interaction input includes touch input.

[0246] In this embodiment, the touch input is implemented by touching the first touch-sensitive area 102a or the second touch-sensitive area 102b. The touch input may include but is not limited to single-point touch, multi-point touch, pressure-sensitive touch, capacitive pen input, etc. The force input is implemented by applying a force based on the second touch-sensitive area 102b, and the force input may include but is not limited to pressing input.

[0247] When the user operates the first touch-sensitive area 102a, a touch input and / or a force input may be performed, for example, the first touch-sensitive area 102a may be lightly tapped or the first touch-sensitive area 102a may be long pressed. When the user operates the second touch-sensitive area 102b, a touch input may be performed, for example, the second touch-sensitive area 102b may be lightly tapped.

[0248] In the above embodiment, since the first interactive input includes touch input and / or force input, and the second interactive input includes touch input, the user can flexibly and conveniently initiate the first interactive input or the second interactive input to efficiently operate the insulin infusion device 100.

[0249] Fig.15 FIG. 1 is a flow chart of a device control method in an embodiment. In an exemplary embodiment, as shown in FIG. Fig.15 As shown, a device control method is provided, which is described by taking the method applied to the processor 904 in the above-mentioned insulin infusion device 100 as an example, including the following S1501 to S1503.

[0250] S1501, entering a low power mode according to a predefined condition.

[0251] S1502: In response to a first interactive input to a first touch-sensitive area during operation in the low-power mode, switch the low-power mode to a full-operation mode.

[0252] S1503: Execute a preset function in response to a second interactive input to the first touch-sensitive area and / or a third interactive input to the second touch-sensitive area during operation in the full working mode.

[0253] The preset functions include at least one of bolus infusion, basal rate infusion, stop infusion, pause infusion, reset filling, user settings, and screen unlock. The low power mode is a mode in which at least one processor 904 in the insulin infusion device 100 enters a dormant state.

[0254] The above device control method is applied to an insulin infusion device 100, which includes a housing 101, a touch screen 102, and at least one processor 904. The touch screen 102 is arranged on the housing 101, and the touch screen 102 includes a first touch-sensitive area 102a and a second touch-sensitive area 102b, and the first touch-sensitive area 102a and the second touch-sensitive area 102b are used to receive interactive input implemented by the user. In this way, the user does not need to use physical buttons to control the insulin infusion device 100, but can control the insulin infusion device 100 more intuitively and quickly through the touch screen 102, which simplifies the operation steps and improves the human-computer experience. Furthermore, since the processor 904 is independently coupled to the first touch-sensitive area 102a and the second touch-sensitive area 102b, respectively, and the processor 904 includes a low-power mode and a full-operation mode, the processor 904 can enter the low-power mode according to a predefined condition, and in response to a first interactive input to the first touch-sensitive area 102a during the operation of the low-power mode, switch the low-power mode to the full-operation mode, and in response to a second interactive input to the first touch-sensitive area 102a and / or a third interactive input to the second touch-sensitive area 102b during the operation of the full-operation mode, switch the low-power mode to the full-operation mode. Interactive input, execute preset functions, the preset functions include at least one of large dose infusion, basal rate infusion, stop infusion, pause infusion, reset filling, user settings, and screen unlocking. Therefore, the first touch-sensitive area 102a and the second touch-sensitive area 102b are independently controlled. On the one hand, during the operation of the low-power mode, the processor 904 will switch the low-power mode to the full working mode only when the first touch-sensitive area 102a receives the wake-up input, which fully considers the interference of human misoperation, avoids other mis-touch changes in the low-power mode, and ensures effective wake-up operation. In addition, the first touch-sensitive area 102a and the second touch-sensitive area 102b need to be used together to realize the preset function. In this way, even if the user mistakenly touches the first touch-sensitive area 102a or the second touch-sensitive area 102b alone, the insulin infusion device 100 will not perform the corresponding action, which also improves the safety and reliability of the insulin infusion device 100. On the other hand, the low-power mode is a mode in which at least one processor 904 enters a dormant state. Entering the low-power mode in time under predefined conditions can extend the use time of the insulin infusion device 100.

[0255] The above-mentioned device control method can refer to the embodiment of the above-mentioned insulin infusion device 100, which will not be described in detail here.
