[0023] DETAILED DESCRIPTION

[0024] In order to have a clearer understanding of the technical features, purposes and effects of the present disclosure, specific embodiments of the present disclosure are now described with reference to the accompanying drawings, in which the same reference numerals represent the same parts.

[0025] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0026] In order to simplify the drawings, only the parts related to the present disclosure are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked.

[0027] In this article, "one" not only means "only one", but also means "more than one". In this article, "first", "second", etc. are only used to distinguish each other, rather than to indicate their importance and order, or the premise of each other's existence.

[0028] It should be understood that the "system", "device", "unit" and / or "module" used herein are a method for distinguishing different components, elements, parts, portions or assemblies at different levels. However, if other words can achieve the same purpose, the words can be replaced by other expressions.

[0029] Flowcharts are used in this disclosure to illustrate the operations performed by the system according to the embodiments of the present disclosure. It should be understood that the preceding or following operations are not necessarily performed precisely in order. Instead, the various steps may be processed in reverse order or simultaneously. At the same time, other operations may also be added to these processes, or one or more operations may be removed from these processes.

[0030] In some embodiments, mobile medical devices are being widely used in various medical institutions due to their advantages such as portability, good mobility, and small footprint. For critically ill patients and patients who are inconvenient to move, it is more convenient to use mobile medical devices to collect images of patients.

[0031] Although mobile medical equipment can be used in orthopedics, wards, emergency rooms, operating rooms and other places in a mobile manner, however, in daily practice, when it needs to be transported to other locations, it is necessary to shut down the entire system, unplug the power plug, then transport the device to another location, reinsert the power plug, and finally press the power button to turn on the system. Since it takes about 1 minute to shut down the system and about 2 minutes to restart, it takes a long time (about 3 minutes, in addition to the time required to move the machine from one location to another) to prepare for patient image acquisition during the system transportation process.

[0032] In view of the above problems, some embodiments of the present disclosure provide a power management method for a mobile medical device. If the device needs to be transported to another location, the user can transport the device without shutting down and restarting the system.

[0033] Exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0034] Figure 1 The present invention is a schematic diagram of a power management system 100 for mobile medical devices in which various methods described herein may be implemented according to an exemplary embodiment. The power management system 100 may be applied to various mobile medical devices, such as a mobile C-arm X-ray system, a mobile direct digital X-ray imaging system (mobile DR), etc.

[0035] refer to Figure 1, the power management system 100 includes a microcontroller board 110, a battery management module 120, a display device 130, an X-ray generator 140, and a power supply module 150. The microcontroller board 110 is connected or communicated with the battery management module 120, the display device 130, the X-ray generator 140, and the power supply module 150, respectively. For example, the microcontroller board 110 and the battery management module 120 can be connected via a universal asynchronous receiver / transmitter (UART) communication. For another example, the microcontroller board 110 and the display device 130 can be connected via Ethernet communication. For another example, the microcontroller board 110 and the X-ray generator 140 can be connected via an X-ray enabling cable.

[0036] In some embodiments, the battery management module 120 can monitor the status of the battery. For example, the battery status can include but is not limited to the battery power, the remaining time of the battery, the connection status of the battery, the overload status of the battery, etc. In some embodiments, the microcontroller board 110 can obtain the current status of the battery from the battery management module 120.

[0037] In some embodiments, the display device 130 can display the captured medical image information. In some embodiments, the microcontroller board 110 can display some power management information on the display device 130. For example, the power management information may include but is not limited to the battery power, the remaining battery time, prompt information, warning information, standby mode information, normal mode information, etc.

[0038] In some embodiments, the X-ray generator 140 can turn on and off each X-ray source and variably control a single X-ray source to emit X-rays to irradiate the object being inspected. In some embodiments, the X-ray generator 140 can include an X-ray generator of a mobile C-arm system, a mobile direct digital X-ray radiography system (mobile DR), etc. In some embodiments, the microcontroller board 110 can control the operation and interruption of the X-ray generator 140.

[0039] In some embodiments, the microcontroller board 110 may obtain a power supply signal from the power supply module 150 to find out the connection status of the external power supply, that is, whether the external power plug is plugged in.

[0040] Figure 2 1 is a flow chart illustrating a power management method 200 for a mobile medical device according to an exemplary embodiment.

[0041] Method 200 can be Figure 1 The power management system 100 shown in FIG. 2 is executed, that is, the execution body of each step of the method 200 may be Figure 1The power management system 100 shown in FIG. 2 is shown in FIG. 2 . Hereinafter, the various steps of the method 200 are described in detail by taking the power management system 100 as an example.

[0042] refer to Figure 2 , method 200 includes steps S210 to S240.

[0043] In step S210, a first state of the battery is obtained, wherein the first state indicates whether the battery can be used normally. In some embodiments, the first state of the battery can be obtained from the battery management module 120. As an example, the battery can be used normally may include that the battery wiring is normal, the battery is not overloaded, the battery is not leaking, the battery is not overloaded, the battery is not short-circuited, etc. By checking whether the battery can be used normally, abnormal conditions in subsequent operations (such as using the battery for power supply) can be avoided.

[0044] In step S220, in response to the first state being able to be used normally, the second state of the battery is obtained, and the second state indicates the remaining power supply capacity of the battery. In some embodiments, the second state of the battery can also be obtained from the battery management module 120. As an example, the second state of the battery may include state parameters such as the battery power, the remaining time of the battery, or the voltage of the battery that can characterize the remaining power supply capacity of the battery. In some embodiments, if it is found that the first state cannot be used normally, a prompt message can be output through the display device 130 to inform the user that the standby mode is not available. Thereafter, if the external power plug is unplugged, the system will shut down immediately.

[0045] In step S230, a first signal is obtained, wherein the first signal indicates the connection status of the external power supply. In some embodiments, the first signal may be obtained from the power supply module 150. In some embodiments, the first signal may include a level signal. In some embodiments, the connection status of the external power supply may include the plugging in of the external power plug or the unplugging of the external power plug. The unplugging of the external power plug may be intentional, or the power plug may be loosened and dropped by itself or accidentally knocked off during operation.

[0046] In step S240, the operating mode of the mobile medical device is determined based on the second state and the first signal. For example, if the second state indicates that the remaining power supply capacity of the battery is particularly sufficient at this time, and the first signal indicates that the external power plug continues to be plugged in, it is determined that the mobile medical device continues to operate in the normal operating mode, and the second state of the battery can continue to be obtained from the battery management module 120. For another example, if the second state indicates that the remaining power supply capacity of the battery is particularly sufficient at this time, and the first signal indicates that the external power plug has been unplugged, it is determined that the mobile medical device enters the standby mode, and the mobile medical device can be transported to another location, such as another operating room, without shutting down the entire system.

[0047] The method 200 determines the operation mode of the mobile medical device based on the second state and the first signal, so that the user can transport the mobile medical device without shutting down the entire system, thereby saving a lot of time and improving the user experience.

[0048] Figure 3 To illustrate a method according to an exemplary embodiment Figure 2 A flowchart of a portion of an exemplary process in method 200. Figure 3 As shown, according to some embodiments, the second state includes the power of the battery, the operating mode includes the standby mode, and step S240, based on the second state and the first signal, determining the operating mode of the mobile medical device may include:

[0049] Step S310, in response to the power level being greater than or equal to a first threshold, determining a first level state of a first signal; and

[0050] Step S320: Based on the first level state, determine whether the mobile medical device enters the standby mode.

[0051] According to some embodiments, step S310, in response to the power being greater than or equal to the first threshold, determining the first level state of the first signal may include: in response to the power being less than the second threshold, outputting a warning message through a display device, wherein the second threshold is greater than the first threshold. According to some embodiments, the first threshold may be 10% of the full power of the battery (when fully charged). According to some embodiments, the second threshold may be 50% of the full power of the battery (when fully charged). For example, if the power is 30% (between 10% and 50%) of the full power of the battery at this time, a warning message is output through the display device 130 to warn the user that it is not recommended to enter the standby mode, but the system will still enter the standby mode without receiving any feedback from the user, but in this case, since the battery power is not particularly sufficient, the standby mode is limited, and the system will shut down faster than when the power is sufficient. For another example, if the power is 70% (greater than 50%) of the full power of the battery at this time, a prompt message is output through the display device 130 to inform the user that the standby mode can be used normally.

[0052] According to some embodiments, the first level state of the first signal may include a high level value "1" and a low level value "0". As an example, the high level value "1" may indicate that the external power plug is plugged in, and correspondingly, the low level value "0" may indicate that the external power plug is unplugged. Of course, it is also understandable that the high level value "1" may also indicate that the external power plug is unplugged, and the low level value "0" may indicate that the external power plug is plugged in.

[0053] Exemplarily, a high level value "1" indicates that the external power plug is plugged in, and a low level value "0" indicates that the external power plug is unplugged. For example, if the power level is 80% of the full power of the battery at this time, and the first level state of the first signal is a low level value "0", it is determined that the mobile medical device enters the standby mode. For another example, if the power level is 30% of the full power of the battery at this time, and the first level state of the first signal is a high level value "1", it is determined that the mobile medical device does not enter the standby mode. For another example, if the power level is 5% of the full power of the battery at this time, there is no need to determine the first level state of the first signal, but a prompt message can be directly output through the display device 130 to inform the user that the standby mode is not available. Thereafter, if the external power plug is unplugged, the system will shut down quickly.

[0054] Figure 4 To illustrate a method according to an exemplary embodiment Figure 3 A flowchart of some example processes in the method. Figure 4 As shown, according to some embodiments, the mobile medical device includes an X-ray generator, and step S320, determining that the mobile medical device enters the standby mode may include:

[0055] Step S410, determining whether the X-ray generator is working; and

[0056] Step S420: In response to determining that the X-ray generator is operating, interrupting the operation of the X-ray generator.

[0057] Since the battery cannot support such a large power consumption of the X-ray generator, it is necessary to check whether the X-ray generator is working after entering the standby mode. If the X-ray generator is working, it is necessary to interrupt the operation of the X-ray generator in a very short time (for example, within a few milliseconds) to avoid overloading the battery.

[0058] According to some embodiments, determining whether the X-ray generator is working can be achieved by obtaining the second level state of the enable signal of the X-ray generator located in the X-ray enable cable. As an example, the second level state of the enable signal may include a high level value "1" and a low level value "0". As an example, a high level value "1" may indicate that the X-ray generator is working, and correspondingly, a low level value "0" may indicate that the X-ray generator is suspended. Of course, it is also understandable that a high level value "1" may also indicate that the X-ray generator is suspended, and a low level value "0" may indicate that the X-ray generator is working. In addition, in addition to interrupting the operation of the X-ray generator, the mobile medical device entering the standby mode may also include: locking the movement of a movable part (e.g., a lifting column), or locking any human-machine interface operation on the display device 130.

[0059] According to some embodiments, step S420, interrupting the operation of the X-ray generator may include: changing the second level state of the enable signal of the X-ray generator. Exemplarily, a high level value "1" indicates that the X-ray generator is working, and a low level value "0" indicates that the X-ray generator is stopped. For example, if it is determined that the second level state of the enable signal of the X-ray generator is a high level value "1" at this time, the second level state of the enable signal may be adjusted to a low level value "0" to interrupt the operation of the X-ray generator.

[0060] Reference again Figure 2 Alternatively or additionally, method 200 may further include steps S250 to S270.

[0061] In step S250, the third state of the battery is obtained, and the third state indicates the remaining power supply capacity of the battery. In some embodiments, the third state can be obtained from the battery management module 120. As an example, the third state of the battery may include a state parameter that can characterize the remaining power supply capacity of the battery, such as the battery power, the remaining time of the battery, or the battery voltage. In some embodiments, after entering the standby mode, the system will continue to monitor the state of the battery and can output the state to the display device 130.

[0062] In step S260, a second signal is obtained, wherein the second signal indicates a connection status of an external power source. In some embodiments, the second signal may be obtained from the power supply module 150. In some embodiments, the second signal may include a level signal. In some embodiments, the connection status of the external power source may include whether an external power plug is plugged in or not plugged in.

[0063] In step S270, based on the third state and the second signal, the operating mode of the mobile medical device is re-determined. For example, if the third state indicates that the remaining power supply capacity of the battery is insufficient at this time, and the second signal indicates that the external power plug is not plugged in, it is determined that the mobile medical device enters the shutdown procedure, and the system shuts down after a certain time interval. For another example, if the third state indicates that the remaining power supply capacity of the battery is insufficient at this time, and the second signal indicates that the external power plug has been re-plugged, it is determined that the mobile medical device can enter the normal mode (also called "wake-up") again, and the mobile medical device can be used normally at this time.

[0064] By redetermining the operating mode of the mobile medical device based on the third state and the second signal, the user can quickly (for example, within 5 seconds) wake up the entire system after transporting the mobile medical device, thereby saving a lot of time and improving the user experience.

[0065] Figure 5 To illustrate a method according to an exemplary embodiment Figure 2A flowchart of a portion of an exemplary process in method 200. Figure 5 As shown, according to some embodiments, the third state includes the remaining time of the battery, and the operating mode also includes a normal mode. Step S270, based on the third state and the second signal, re-determining the operating mode of the mobile medical device may include:

[0066] Step S510, in response to the remaining time being greater than zero, determining a second level state of the second signal; and

[0067] Step S520: based on the second level state, re-determine whether the mobile medical device enters the normal mode.

[0068] The remaining battery time is calculated by the battery management module 120 based on the remaining battery power and the power consumption of the device in the standby mode, for example.

[0069] According to some embodiments, the second level state of the second signal may include a high level value "1" and a low level value "0". As an example, the high level value "1" may indicate that the external power plug is plugged in, and correspondingly, the low level value "0" may indicate that the external power plug is not plugged in. Of course, it is also understandable that the high level value "1" may also indicate that the external power plug is not plugged in, and the low level value "0" may indicate that the external power plug is plugged in.

[0070] Exemplarily, a high level value "1" indicates that the external power plug is plugged in, and a low level value "0" indicates that the external power plug is not plugged in. For example, if the remaining time is 2 seconds at this time, and the second level state of the second signal is a low level value "0", it is determined that the mobile medical device will shut down the entire system after 2 seconds. For another example, if the remaining time is 5 seconds at this time, and the second level state of the second signal is a high level value "1", it is determined that the mobile medical device re-enters the normal mode.

[0071] According to some embodiments, the remaining time of the battery can be displayed on the display device 130. According to some embodiments, after determining that the mobile medical device has re-entered the normal mode, a prompt message can be output through the display device 130 to inform the user to re-enter the normal mode. According to some embodiments, after entering the normal mode, the battery power and other information can be re-displayed on the display device 130.

[0072] It should be noted that if the remaining battery time is equal to zero, it does not necessarily mean that the battery power is completely exhausted. When designing a power management system, a certain margin is often left for the battery power to better maintain the battery life.
