[0090] To fully understand this invention, a detailed structure will be presented in the following description to illustrate the technical solution proposed by this invention. Optional embodiments of the invention are described in detail below; however, in addition to these detailed descriptions, the invention may have other embodiments.

[0091] The first aspect of this invention provides a medical ventilation device. See also... Figure 1 The medical ventilation device 100 includes a ventilation device 110, a ventilation tubing 120, at least one physical key 130, a processor 140, and a display screen 150. The ventilation device 110 generates gas at a set pressure or flow rate; the ventilation tubing 120 connects to the patient's respiratory system to deliver gas to the patient; the processor 140 has a sleep state and an operating state; the display screen 150 displays the device interface when the processor 140 is in the operating state; the physical key 130 includes a display module and is associated with a first target operation when the processor 140 is in the operating state; when the processor 140 is in the sleep state, it is awakened to the operating state according to a preset trigger condition, acquires the current device status information of the medical ventilation device 100, and controls the display module to display the device status information; when the processor 140 is in the operating state, it controls the display module to display the identifier of the first target operation; the processor 140 is also used to execute the first target operation associated with the physical key 130 based on a first operation command received from the physical key 130.

[0093] In possible embodiments, the working states under the different conditions described above are explained. The first condition is that the processor is awakened from the sleep state to the working state according to a preset trigger condition. The second condition is that the processor is in the working state.

[0094] The difference between the two is that the first case is not the working state entered by the power button of the medical ventilation equipment, while the second case is the working state entered by the power button of the medical ventilation equipment.

[0095] The difference between the two is as follows: In the first case, after being woken up to the working state, it will automatically enter the sleep state; in the second case, after being in the working state, it will enter the sleep state through the power button.

[0096] In both of the above situations, the medical ventilation equipment may enter a sleep state from the working state or the entire machine may enter a power-off state because it is not charged and the battery is low.

[0097] The aforementioned power on / off buttons can be buttons on the medical ventilation equipment itself, or operation buttons on other remote or remote control devices that can be used to enable power on / off functions.

[0098] The medical ventilation device 100 of this embodiment includes at least one physical key 130 with a display module. The physical key includes the display module. The processor 140 of the medical ventilation device 100 can be woken up from a sleep state and control the display module to display device status information, so that the user can view the device status information without using the display screen. The physical key can also be used to trigger a target operation when the processor is in working state, so as to realize the function reuse of the physical key.

[0099] The medical ventilation device 100 of this invention includes medical devices with ventilation functions such as ventilators and anesthesia machines. The medical ventilation device is used to replace, control, or alter the physiological breathing of the ventilated individual, improving the respiratory function and reducing respiratory exertion by increasing lung ventilation. In some embodiments, the medical ventilation device 100 can be implemented as a transport ventilator, which can be used for transporting ventilated individuals between different departments within a hospital, or for long-distance pre-hospital transport such as by ambulance.

[0100] The ventilation tubing 120 of the medical ventilation device 100 includes at least an inspiratory branch; the ventilation tubing 120 may also include an inspiratory branch and an expiratory branch. The inspiratory branch is used to deliver gas supplied by a gas source to the ventilated individual, and the expiratory branch is used to receive gas exhaled by the ventilated individual. The gas supplied by the gas source may include air, oxygen, or an air-oxygen mixture; in some embodiments, the gas may also include aerosol drugs or anesthetics. The gas supplied by the gas source may be, for example, compressed gas supplied by a central gas supply system, high-pressure gas supplied by a gas cylinder, or gas from the environment. The ventilation device 110 is connected to a processor 140 and generates gas at a set pressure or flow rate under the control of the processor 140. The ventilation device may include pressure generating devices such as turbines or valves.

[0101] Exemplarily, the ventilation line 120 also includes sensors. The sensors and processor 140 can be connected via a wired or wireless communication protocol to enable data exchange between them. Exemplarily, the sensors include at least a flow sensor and a pressure sensor; the flow sensor detects the flow rate of gas supplied to the ventilated individual, and the pressure sensor detects the pressure within the ventilation line 120. In some embodiments, some sensors may be independently located outside the medical ventilation device 100, but detachably connected to it.

[0102] The processor 140 of the medical ventilation device 100 can be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The processor can be a microcontroller unit (MCU), or any conventional processor. The medical ventilation device 100 also includes a memory. The memory stores ventilation parameter data for the patient in the medical ventilation device 100, and also stores program code. The processor 140 uses the program code in the memory to execute steps in the control method. The processor 140 has a sleep state and a working state. In the working state, the display 150 is powered on and the medical ventilation device 100 is fully powered on. The sleep state can be a power-off state or a low-power state. The power consumption in the low-power state is lower than that in the working state. For example, the power consumption in the low-power state is 10% to 50% of the power consumption in the working state. When the processor 140 is in the low-power state, at least the display 150 is not powered on.

[0103] In some embodiments, the processor 140 includes at least one processing unit, which includes a processing unit for connection to at least one module.

Exemplarily, the processor 140 includes at least a first processor connected to a power module, a second processor connected to the ventilator 110 and the ventilator 120, a third processor connected to the display screen 150, and a fourth processor connected to the physical button 130. The processing unit can be any one of the first, second, third, and fourth processors, and each of the first, second, third, and fourth processors can include at least one processor. In some embodiments, the first and fourth processors can be the same processor, i.e., the power module and the physical button 130 can share the same processor. In some embodiments, the first, second, and fourth processors are the same processor, i.e., the power module, the ventilator 110, the ventilator 120, and the physical button 130 can share the same processor.

[0104] The display screen 150 is used to provide a visual display output to the user. Specifically, the display screen 150 is used to display the device interface when the processor 140 is in an active state. The processor 140 being in an active state can refer to the processor 140 used to control the display screen 150 being active. Specifically, the display screen 150 can display the device interface when the medical ventilation device 100 is powered on. Exemplarily, the display screen 150 can be implemented as a touch display, or a display screen 150 with an input panel, that is, the display screen 150 can function as an input / output device.

[0105] For example, in order to realize user interface and data exchange, in addition to display screen 150, medical ventilation device 100 may also include other input / output devices connected to processor 140, including but not limited to input devices such as keyboard, mouse, touch screen, remote control, etc., and output devices including but not limited to printer, speaker, etc.

[0106] Furthermore, the medical ventilation device 100 also includes a power module for supplying power to the medical ventilation device 100 in the event of a lack or malfunction of external power. The power module includes a battery, charging circuitry, etc.

[0107] The medical ventilation device 100 of this embodiment of the invention is provided with at least one physical key 130, used to display device status information when the medical ventilation device 100 is turned off, and used as a function key when the medical ventilation device 100 is turned on. For example, when the medical ventilation device 100 has at least two physical keys 130, different physical keys 130 can be used to display different device status information and to trigger different target operations. The physical keys 130 can be positioned in the same location as the display screen 150 for convenient user operation and viewing of device status information. For example, see... Figure 2 The physical key 130 can be located below the display screen 150 along with the power button and other function keys.

[0108] For example, the physical key 130 can be implemented as a button, meaning a user can press the physical key 130 to trigger the processor 140 to perform a first target operation. In this example, the physical key 130 may also include a button housing with a pressing portion. At least the pressing portion of the button housing is made of transparent material, and a display module is disposed below the pressing portion, allowing the displayed content to be shown through the pressing portion for the user to view. The button housing may have a cavity in which the display module is disposed; alternatively, the button housing may be a semi-enclosed structure with the display module disposed below it. In another example, the physical key 130 can be implemented as a knob, meaning a user can rotate the physical key 130 to trigger the processor 140 to perform the first target operation.

[0109] The display module of the physical key 130 can be a bistable display module. Bistable means that each display unit can maintain two stable states without the aid of electricity or other external forces, thus allowing the bistable display module to still display the image when power is off, significantly reducing power consumption. If the display module is a bistable display module, the processor 140 is also used to control the processor 140 to enter a sleep state after the display module displays device status information, while the display module can continue to display device status information. When the processor 140 is woken up, it can control the bistable display module to refresh the device status information. After the processor 140 enters a sleep state, the bistable display module maintains the original information display until the processor 140 is woken up again.

[0110] For example, the bistable display module can be an electronic ink bistable display module. An electronic ink bistable display module consists of a large number of microcapsules, each filled with a dielectric fluid and colored particles. By changing the positive and negative charges, the colored particles can be arranged in an orderly manner, thus determining the displayed color. After the image is formed, the colored particles stop moving, and the image will not disappear even after power is turned off, thus exhibiting bistable display characteristics. The electronic ink bistable display module can also be a monochrome electronic ink bistable display module, where the colored particles are white; it can also be a color electronic ink display module, where green, red, yellow, and other colored particles are mixed into the white particles to achieve a color display effect.

[0111] Alternatively, the bistable display module can also be a liquid crystal bistable display module. Specifically, a liquid crystal bistable display module can include a cholesteric liquid crystal bistable display module. Cholesteric liquid crystal is a special liquid crystal mode with a helical arrangement. This special arrangement is achieved by adding an optical rotator to a nematic liquid crystal, and the display effect is achieved by utilizing the two different polarized rotation states of cholesteric liquid crystal molecules—reflection and transmission—under different potentials. Cholesteric liquid crystal display modules also utilize ambient light to display images and possess bistable characteristics.

[0112] Besides the two types of bistable display modules mentioned above, the bistable display module in this embodiment of the invention can be any bistable display technology that has bistable display characteristics. This embodiment of the invention does not limit the specific bistable display technology.

[0113] In some embodiments, the display module can also be a conventional LCD screen. The LCD screen displays device status information when powered by the power module, and stops displaying the device status information after power failure. When a conventional LCD screen is used, the processor 140 can be woken up in response to a third operation command on the physical key 130 and control the LCD screen to display the device status information. Thus, although the display module cannot continue displaying after power failure, the user can still view the device status information by operating the physical key 130 when needed.

[0114] If the display module is an LCD screen, the processor 140 can enter a sleep state after the display module has displayed device status information for a preset duration. In this state, the display module will no longer display device status information, thereby saving power. Alternatively, the processor 140 can enter a sleep state in response to another operation command on the physical key 130. That is, when the user operates the physical key 130 for the first time, the display module displays device status information; when the user operates the physical key 130 again, the display module no longer displays device status information.

[0115] As described above, when the processor 140 is in a sleep state, it is woken up to a working state according to a preset trigger condition, obtains the current device status information of the medical ventilation device, and controls the display module to display the device status information. Here, the processor 140 being woken up to a working state according to the preset trigger condition means that at least the processor 140 used to control the display module is woken up to a working state. At this time, at least one of the processors 140 used to control the display screen 150, the ventilation device 110, and the ventilation tubing 120 is in a power-off state, meaning the display module is used to display device status information when the medical ventilation device 100 is in a power-off state. For example, when the display module displays device status information, at least the processor used to control the display screen 150 is in a power-off state, meaning the display screen 150 is not lit.

[0116] In one embodiment, the processor 140 can wake itself up at a set frequency. For example, it can wake itself up once every half hour or once every hour. The user can adjust the set frequency of the self-wake-up as needed. Alternatively, the processor 140 can wake itself up at a set time, for example, at the same time every day or at a set time on a set date.

[0117] For example, since the medical ventilation device 100 does not require consideration of power consumption during charging and battery power information is updated rapidly, the processor 140 self-wakes up at a first preset frequency when the medical ventilation device 100 is being charged, and at a second preset frequency when the medical ventilation device 100 is not being charged. The first preset frequency is higher than the second preset frequency. For instance, when the medical ventilation device 100 is being charged, the processor 140 self-wakes up once every five minutes, and when the medical ventilation device 100 is not being charged, the processor 140 self-wakes up once every hour. It is understood that the above self-wake-up frequencies are merely examples and not limitations.

[0118] Alternatively, the processor 140 can be woken up in response to the medical ventilation device starting to charge. For example, when the device status information is charging status information, waking up the processor 140 when the medical ventilation device starts charging can control the display module to display the charging status information in a timely manner, prompting the user that the medical ventilation device is currently charging.

[0119] Alternatively, the processor 140 can be woken up in response to a third operation command on the physical key 130, which is also used to associate with a wake-up operation when the processor 140 is in a sleep state. Thus, the user can operate the physical key 130 at any time to wake up the processor 140, causing the processor 140 to control the display module to display device status information. When the display module is a bistable display module, the user can operate the physical key 130 at any time to refresh the device status information displayed on the display module.

[0120] Of course, the above wake-up strategies can be combined. That is, under normal circumstances, the processor 140 wakes up automatically at a set frequency or time. At the same time, the processor 140 will also be woken up when the medical ventilation device 100 starts charging or when the physical button 130 receives a third operation command.

[0121] The device status information displayed on the display module of physical key 130 may include battery power information and / or charging status information related to the battery of the medical ventilation device 100. The battery power information includes a power value and a power level indicator; the power value is the remaining percentage, and the power level indicator is low or not low. The charging status information indicates whether the battery is currently being charged, i.e., whether an external power source is connected. Users can view the battery power information and / or charging status information through the display module of physical key 130 without turning on the device, ensuring that the medical ventilation device has sufficient power for immediate use.

[0122] The device status information displayed by the display module of physical key 130 may also include gas source pressure status information related to the gas source of medical ventilation equipment 100. The gas source pressure status information includes whether the pressure of air and / or oxygen meets the usage conditions. Displaying the gas source status information helps to avoid the problem of gas source unavailability when medical ventilation equipment 100 needs to be used.

[0123] The device status information displayed by the display module of physical key 130 may also include the previous self-test result of the medical ventilation device 100. The self-test result may include whether the flow rate, pressure, and oxygen concentration meet the standards, or whether the self-test passed. For example, after the medical ventilation device 100 is powered on and performs a self-test, it stores the self-test result in the memory. The processor 140 retrieves the self-test result stored in the memory and controls the display module to display the self-test result. The self-test result displayed by the display module may be the result within a preset time period. If there is no self-test result within the preset time period, the display module can display that there is no valid self-test result to ensure that the self-test result displayed by the display module is valid.

[0124] The device status information displayed by the display module of physical key 130 may also include the electrical signal status of the medical ventilation device 100, which may be the real-time current and voltage values ​​of the medical ventilation device. The device status information may also include the turbine speed information of the medical ventilation device 100, i.e., whether the turbine can reach the speed indicated by the operating command. The device status information may also include fault information of the medical ventilation device 100, used to prompt the user to troubleshoot promptly.

[0125] When displaying device status information, the display module can use numbers, text, graphics, etc. For example, battery information can be displayed as "Battery 80%" or "80%", or a graphic representing the remaining battery level. Furthermore, the display module can directly display device status information for a more intuitive presentation; it can also display device status information via QR code, allowing users to scan the code with their mobile phones or other client devices to view the device status information. When displaying device status information via QR code, a smaller display module can provide users with richer information.

[0126] In some embodiments, the device status information displayed by the display module of the physical key 130 can be defined by the user, and the user can select the device status information to be displayed by the display module from the above device status information.

[0127] In this embodiment of the invention, the physical key 130 is also used as a function key when the processor 140 is in an operating state. The processor 140 is also used to execute a first target operation associated with the physical key 130 based on a first operation instruction received by the physical key 130. For example, the processor 140 being in an operating state can mean that the processor 140 used to control the power module, the physical key 130, the display screen 150, the ventilation device 110, and the ventilation tubing 120 are all in an operating state, that is, the medical ventilation device 100 is in a powered-on state.

[0128] In one embodiment, the first target operation may include switching the device interface displayed on the display screen 150 between daytime and nighttime modes. For example, when the user presses physical key 130, the device interface switches from daytime mode to nighttime mode; when the user presses physical key 130 again, the device interface switches from nighttime mode back to daytime mode. Alternatively, the first target operation may include switching the device interface between outdoor and indoor modes. For example, when the user presses physical key 130, the device interface switches from outdoor mode to indoor mode; when the user presses physical key 130 again, the device interface switches from indoor mode back to outdoor mode. Alternatively, the first target operation may include toggling between displaying and not displaying a menu bar on the device interface; toggling between displaying and not displaying alarm limits on the device interface; and toggling between displaying and not displaying a fogging interface on the device interface. For example, when the user presses physical key 130, a menu bar is displayed on the device interface; when the user presses physical key 130 again, the menu bar is no longer displayed on the device interface. In addition, the first target operation associated with physical key 130 may include other operations that switch between at least two different states.

[0129] To indicate the function of physical key 130 to the user, processor 140 is also used to control the display module to display an identifier of the first target operation during operation. For example, the identifier of the first target operation can be customized by the user to meet their individual needs.

[0130] In one embodiment, when the processor 140 is operational, it is further configured to adjust the operation associated with the physical key 130 from a first target operation to a second target operation based on an adjustment instruction input by the user, and control the display module to display an identifier of the second target operation. The processor 140 is also configured to execute the second target operation associated with the physical key based on a second operation instruction received by the physical key. In other words, the user can adjust the target operation associated with the physical key 130 as needed. Since one physical key 130 can be used to implement different functions, the number of function keys required for the medical ventilation device 100 can be reduced, which helps simplify design and reduce costs.

[0131] In some embodiments, the physical key 130 further includes an illumination module for illuminating the display module. The illumination module can be located inside or outside the physical key 130. The illumination module allows users to clearly see the device status information or the identifier of the first target operation displayed on the display module even in dark environments. This is especially important for bistable display modules, which reflect light rather than directly; the presence of the illumination module makes it easier for users to see the content displayed on the bistable display module. Exemplarily, the illumination module can employ front illumination or refracted illumination.

[0132] In one embodiment, the physical key 130 is also used to associate with a lighting operation to start the lighting module when the processor 140 is in a sleep state; the processor 140 is also used to control the lighting module to illuminate the display module based on a fourth operation instruction received by the physical key 130. That is, when the processor 140 is in a sleep state, the lighting unit starts and illuminates the display module when the user operates the physical key 130, making operation convenient.

[0133] In one embodiment, the processor 140 is further configured to control the lighting module to illuminate the display module when the acquired device status information is preset device status information. That is, when the display module is lit up, it indicates that the current device status information is the preset device status information, so as to prompt the user to check the display module and pay attention to the preset device status information in a timely manner. The preset device status information may be, for example, low battery or other device status information that the user needs to pay attention to.

[0134] It should be understood that, Figure 1 This is merely an example of the components included in the medical ventilation device 100 and does not constitute a limitation on the medical ventilation device 100. Furthermore, the medical ventilation device 100 may include components that are more numerous than those described above. Figure 1 This can be a combination of more components, or different components.

[0135] In summary, the medical ventilation device 100 of this embodiment of the invention has at least one physical key, which includes a display module. The processor of the medical ventilation device can be woken up from the sleep state and control the display module to display device status information, so that the user can view the device status information without using the display screen. The physical key can also be used as a function key when the processor is in the working state, thereby realizing the function reuse of the physical key.

[0136] Below, we will refer to Figure 3A medical ventilation device according to another embodiment of the present invention is described. The medical ventilation device includes a ventilation device 310, a ventilation line 320, at least one physical key 330, multiple processors 340, a display screen 350, and a power module 360, wherein: the ventilation device 310 is used to generate gas at a set pressure or a set flow rate; the ventilation line 320 is used to connect to a patient's respiratory system to deliver gas to the patient; the multiple processors 340 include at least a first processor 340A connected to the power module 360, a second processor 340B connected to the ventilation device 310 and the ventilation line 320, a third processor 340C connected to the display screen 350, and a fourth processor 340D connected to the physical key; at least one target processor among the first processor 340A, second processor 340B, third processor 340C, and fourth processor 340D has a sleep state and an operating state, and the processing other than at least one target processor... The device has a power-off state and an operating state; the display screen 350 is used to display the device interface when the third processor 340C is in the operating state; the physical key 330 includes a display module, and the physical key 330 is used to associate with a first target operation when the fourth processor 340D is in the operating state; when the target processor is in a sleep state, the target processor is woken up to the operating state according to a preset trigger condition, the first processor 340A and / or the second processor 340B obtain the current device status information of the medical ventilation device, and the fourth processor 340D controls the display module to display the device status information; when the target processor is in the operating state, the fourth processor 340D controls the display module to display the identifier of the first target operation; the third processor 340C is also used to execute the first target operation associated with the physical key 330 based on the first operation instruction received by the physical key 330.

[0137] The device status information includes at least one of the following: battery power information and / or charging status information related to the power module 360 ​​of the medical ventilation device acquired by the first processor 340A; air source pressure status information related to the air source of the medical ventilation device acquired by the second processor 340B; the previous device self-test result of the medical ventilation device acquired by the second processor 340B; the electrical signal status of the medical ventilation device acquired by at least one of the multiple processors; turbine speed information of the medical ventilation device acquired by the second processor 340B; and fault information of the medical ventilation device acquired by the second processor 340B.

[0138] In some embodiments, the first processor 340A and the fourth processor 340D are the same processor. This processor is used to simultaneously control the power module 360 ​​and the physical button 330. In some embodiments, the first processor 340A, the second processor 340B, and the fourth processor 340D are the same processor, which is used to simultaneously control the power module 360, the physical button 330, the venting device 310, and the venting line 320. Of course, the first processor 340A, the second processor 340B, the third processor 340C, and the fourth processor 340D can also be different processors.

[0139] For example, when the target processor is in a sleep state, it is woken up to a working state according to a preset trigger condition, while other processors remain in a power-off state. The woken-up target processor may be the first processor 340A and the fourth processor 340D; in some embodiments, if device status information needs to be obtained from the second processor 340B, the woken-up target processor may also include the second processor 340B. When the target processor is woken up, the third processor 340C remains in a power-off state, meaning that the display screen 350 will not be turned on at this time.

[0140] For example, the target processor is woken up according to preset triggering conditions, including: the target processor waking up automatically at a set frequency; or, the target processor waking up automatically at a set time; or, the target processor being woken up in response to the medical ventilation device starting to charge; or, the target processor being woken up in response to a third operation command on physical key 330, which is also used to associate with the wake-up operation when the target processor is active. For example, the first processor 340A is woken up first, powering on the second processor 340B and the fourth processor 340D, thereby waking up the second processor 340B and the fourth processor 340D.

[0141] For example, the display module of the physical key 330 can be a bistable display module with a power-off display function. The target processor is further configured to enter a sleep state after the display module displays device status information, while the display module can continue to display device status information. The bistable display module can be a liquid crystal bistable display module or an e-ink bistable display module. Alternatively, the display module can also be an LCD screen without a power-off display function, and the target processor is further configured to enter a sleep state after the display module displays device status information for a preset duration, thereby saving power consumption.

[0142] The medical ventilation device 300 of this embodiment has at least one physical key, which includes a display module. The processor of the medical ventilation device can be woken from a sleep state and control the display module to display device status information, allowing the user to view the device status information without using a display screen. The physical key can also be used as a function key when the processor is in working state, enabling the same physical key to perform multiple functions. More details of the medical ventilation device 300 can be found in the relevant description of the medical ventilation device 100, and will not be repeated here.

[0143] Below, we will refer to Figure 4 A control method for a medical ventilation device according to an embodiment of the present invention is described. Figure 4 This is a schematic flowchart of a control method 400 for a medical ventilation device according to an embodiment of the present invention. The medical ventilation device for implementing this method has a sleep state and an operating state. The sleep state may be that at least one processor of the medical ventilation device is in a sleep state, and the operating state may be that at least one component of the medical ventilation device is in an operating state. The medical ventilation device includes at least one physical key, which includes a display module. The physical key is used to associate with a first target operation when the medical ventilation device is in the operating state. The medical ventilation device for implementing this method may be a reference... Figure 1 or Figure 3 For the sake of brevity, the following description only describes the main steps of the control method 400 for the medical ventilation device according to an embodiment of the present invention. More specific details can be found above.

[0144] like Figure 4 As shown, the control method 400 for a medical ventilation device according to an embodiment of the present invention includes the following steps:

[0145] In step S410, when the medical ventilation device is in the dormant state, it is awakened to the working state according to a preset trigger condition, the current device status information of the medical ventilation device is obtained, and the device status information is displayed through the display module;

[0146] The device status information includes at least one of the following: battery power information and / or charging status information related to the battery of the medical ventilation device, air source pressure status information related to the air source of the medical ventilation device, the last self-test result of the medical ventilation device, the electrical signal status of the medical ventilation device, the turbine speed information of the medical ventilation device, and the fault information of the medical ventilation device.

[0147] In step S420, when the medical ventilation device is in the working state, the display module displays the identifier of the first target operation, receives the first operation instruction for the physical key, and executes the first target operation based on the first operation instruction.

[0148] The display module for the physical keys can be a bistable display module or an LCD screen. The bistable display module can be a liquid crystal bistable display module or an e-ink bistable display module. If the display module is an LCD screen, the medical ventilation device can enter a sleep state after displaying device status information for a preset time; alternatively, if the display module is a bistable display module, the medical ventilation device can enter a sleep state after displaying device status information, while the display module can continue to display device status information.

[0149] For example, the device status information displayed by the display module includes battery power information and / or charging status information related to the battery of the medical ventilation device. The device status information may also include the previous device self-test results of the medical ventilation device and / or fault information of the medical ventilation device.

[0150] For example, the first target operation associated with the physical key includes any one of the following: switching the device interface of the medical ventilation device between daytime mode and nighttime mode; switching the device interface between outdoor mode and indoor mode; switching between displaying and not displaying the menu bar in the device interface; switching between displaying and not displaying alarm limits in the device interface; and switching between displaying and not displaying the nebulization interface in the device interface. The method may further include: when the medical ventilation device is in operation, adjusting the operation associated with the physical key from the first target operation to a second target operation based on an adjustment command input by the user; controlling the display module to display an identifier of the second target operation; and executing the second target operation associated with the physical key based on the second operation command received by the physical key.

[0151] For example, being woken up to the working state according to a preset trigger condition includes: self-wake-up at a set frequency; or self-wake-up at a set time; or being woken up in response to the medical ventilation device starting to charge; or being woken up in response to a third operation command on the physical key, wherein the physical key is also used to associate with the wake-up operation when the medical ventilation device is in a dormant state. Further, if self-wake-up is performed at a set frequency, then when the medical ventilation device is being charged, it self-wakes up at a first set frequency, and when the medical ventilation device is not being charged, it self-wakes up at a second set frequency, wherein the first set frequency is higher than the second set frequency.

[0152] Furthermore, the physical key also includes an illumination module for illuminating the display module. The physical key is also associated with activating the illumination module when the medical ventilation device is in a dormant state; specifically, the illumination module can be controlled to illuminate the display module based on a fourth operation command received by the physical key, or it can be controlled to illuminate the display module when the device status information is a preset device status information. The preset device status information includes, but is not limited to, low battery information.

[0153] The control method 400 for a medical ventilation device in this embodiment of the invention wakes the medical ventilation device from a dormant state to a working state and displays the device status information through a display module, so that the user can view the device status information without having to use a display screen; when the medical ventilation device is in a working state, a first target operation is executed based on a first operation instruction for a physical key, thereby enabling the physical key to perform function reuse.

[0154] Another aspect of the present invention provides a medical ventilation device, referring to... Figure 5 The medical ventilation device 500 includes a ventilation device 510, a ventilation line 520, at least one physical key 530, a processor 540, and a display screen 550, wherein: the ventilation device 510 is used to generate gas at a set pressure or a set flow rate; the ventilation line 520 is used to connect to the patient's respiratory system to deliver gas to the patient; the processor 540 has a sleep state, a first operating state, and a second operating state; the display screen 550 is used to display the device interface when the processor 540 is in the second operating state; the physical key 530 includes a display module, and the physical key 550 is used to associate with a first target operation when the processor 540 is in the second operating state.

[0155] For example, the second operating state can be a normal operating state, in which the display 550 is powered on and the medical ventilation device 500 is fully powered on. The sleep state is a power-off state or a low-power state, where the power consumption of the low-power state is lower than that of the second operating state. For example, the power consumption of the low-power state is 10% to 50% of that of the second operating state, and when the processor 140 is in a low-power state, at least the display 150 is not powered on.

[0156] The power consumption in the first operating state is lower than that in the second operating state, but higher than that in the sleep state; and in the second operating state, at least the display screen 550 is not powered on. When the processor 540 is in the sleep state, the processor 540 is woken up to the first operating state according to a preset trigger condition, obtains the current device status information of the medical ventilation device, and controls the display module to display the device status information. At this time, the processor 540 is used to control the power supply to the modules related to the device status information and at least one physical key 530, so as to obtain the device status information and cause the physical key 530 to display the device status information.

[0157] When the processor 540 is in the second operating state, it controls the power supply to the ventilation device 510, at least one physical key 530, and the display screen 550, causing the display screen 550 to display the device interface and the entire device to start operating. In the second operating state, the processor 540 also controls the display module of the physical key 530 to display the identifier of the first target operation; the processor 540 also executes the first target operation associated with the physical key 530 based on the first operation instruction received by the physical key 530.

[0158] The device status information displayed by the display module includes at least one of the following: battery power information and / or charging status information related to the battery of the medical ventilation device; air source pressure status information related to the air source of the medical ventilation device; the previous self-test result of the medical ventilation device; the electrical signal status of the medical ventilation device; and fault information of the medical ventilation device. In some embodiments, the device status information also includes turbine speed information of the medical ventilation device 500.

[0159] For example, the target operation associated with physical key 530 can be configured by the user. Specifically, when processor 540 is in the second operating state, processor 540 is further configured to adjust the operation associated with physical key 530 from a first target operation to a second target operation based on the adjustment instruction input by the user, control the display module to display the identifier of the second target operation, and processor 540 is further configured to execute the second target operation associated with physical key 530 based on the second operation instruction received by physical key 530.

[0160] In possible embodiments, the first and second operating states are further described as follows:

[0161] The difference between the two can be: the first working state is not entered by pressing the power button on the medical ventilation device, while the second working state is entered by pressing the power button on the medical ventilation device.

[0162] The difference between the two is that after the first working state, it will automatically enter the sleep state; after the second working state, it will enter the sleep state by pressing the power button.

[0163] In both of the above working states, the medical ventilation equipment may enter a sleep state or the entire machine may enter a power-off state because it is not charged and the battery is low.

[0164] The aforementioned power on / off buttons can be buttons on the medical ventilation equipment itself, or operation buttons on other remote or remote control devices that can be used to enable power on / off functions.

[0165] The medical ventilation device 500 of this embodiment is similar to the medical ventilation device 100 described above, both including physical keys with a display module. The physical keys are used to display device status information when the display screen is not powered on, allowing the user to view the device status information without needing to access the display screen. The physical keys are also used to receive a first operation command when the display screen is powered on, thus enabling the physical keys to perform multiple functions. Further details regarding the medical ventilation device 500 can be found in the description of the medical ventilation device 100, and will not be repeated here.

[0166] This invention also provides a control method for a medical ventilation device, wherein the medical ventilation device can be as follows: Figure 5 The illustrated medical ventilation device includes at least one physical key, which includes a display module. The device has a sleep state, a first operating state, and a second operating state. When the device is in the first operating state, modules related to device status information and at least one physical key are powered on.
