Description

Technical Field

[0001] This invention relates to a ventilation device for anesthesia, a method for maintaining inhalation and starting the device, and a central station. Background Technology

[0002] With economic development and improved living standards, more and more people are keeping pets, leading to a surge in the number of pet hospitals and increasingly specialized veterinary services. When an animal has lung inflammation or tumors, a chest X-ray is necessary.

[0003] When taking a chest X-ray, it is generally necessary to take a deep breath to increase the amount of air in the lungs, making the lung field clearer and helping to show lung tissue and lesions; at the same time, it is also required to hold your breath at the end of the inhalation, in order to avoid motion blur caused by breathing.

[0004] Human patients follow verbal instructions from doctors to inhale, hold their breath, and exhale during chest imaging. However, animal patients cannot understand or follow these instructions.

[0005] Therefore, taking pictures of animals, such as chest X-rays, is a difficult task. Invention Overview

[0127] Embodiments of the present invention

[0128] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0129] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0130] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0131] In one approach, the animal is anesthetized via intravenous injection. The user (e.g., a veterinarian) then places the anesthetized animal on the table of a radiographic imaging device (e.g., an X-ray machine, DR device, or CT scanner), positions it, observes the animal's breathing, and activates the imaging device to capture an image the instant the animal inhales. This approach requires the user to observe the animal's breathing first, and the animal continues to breathe during the image capture process, meaning the lungs are still moving. This can result in blurry images and unclear lung fields, necessitating continuous imaging and leading to a low success rate.

[0132] In one approach, the user (e.g., a doctor) connects the animal to an anesthesia machine next to the radiographic imaging equipment in a shielded room. The user operates the anesthesia machine to deliver anesthetic gas to the animal and maintain the inhalation. The user then operates a hand or foot brake on the radiographic imaging equipment to initiate exposure and take the image. Afterward, the user operates the anesthesia machine to stop the inhalation and maintain the inhalation. While this approach ensures the quality of the captured images, it exposes the doctor to radiation, which could be detrimental to the doctor's health in the long run.

[0133] In one approach, some manufacturers equip anesthesia machines with remote control devices, allowing doctors to initiate the anesthesia machine's inspiratory hold from outside the shielded room, thus protecting them from radiation exposure from the imaging equipment. Other manufacturers establish communication between the anesthesia machine and the imaging equipment, enabling them to work together to perform inspiratory hold simultaneously with imaging. For example, during the inspiratory hold phase, the anesthesia machine automatically notifies the imaging equipment to initiate exposure for imaging. However, these solutions not only increase design complexity and cost but also have poor compatibility with other brands of equipment, resulting in several drawbacks.

[0134] This application proposes a ventilation device for anesthesia, which is capable of maintaining inhalation in animals. To facilitate image capture by a radiographic imaging device, the ventilation device has a delayed inhalation maintenance function. That is, when the inhalation maintenance function of the ventilation device is activated, the device performs the inhalation maintenance action after a preset delay time, allowing the user (e.g., a physician) to leave the shielded room during this time. Simultaneously, the ventilation device can also provide information about the inhalation maintenance status to remind the user outside the shielded room (e.g., how much delay time remains, or whether the inhalation maintenance function is in progress). The user can then initiate the radiographic imaging device's capture based on the current inhalation maintenance status reminder outside the shielded room, thus achieving a low-cost radiographic imaging solution for animals with excellent brand / model compatibility.

[0135] Please refer to Figure 1 As one application scenario of this application, a radioactive imaging device 10 and a ventilation device 30 are placed in a shielded room. The ventilation device 30 can keep the animal breathing to cooperate with the radioactive imaging device 10 to take pictures of the animal.

[0136] In some embodiments, the radioactive imaging device 10 images the animal using radioactive rays. For example, the radioactive imaging device is an X-ray imaging device or a computed tomography (CT) scanner.

[0137] In some embodiments, the radioactive imaging device 10 may also include a remote operating terminal. In some embodiments, the remote operating terminal and the main body of the radioactive imaging device 10 are positioned at a certain distance to facilitate remote operation by the user. For example, as described above, the main body of the radioactive imaging device 10 is placed inside a shielded room, while the remote operating terminal is placed outside the shielded room. This allows the user to trigger the radioactive imaging device 10 to operate, such as starting imaging, by sending a command / instruction to the remote operating terminal, for example, with a single click.

[0138] Please refer to Figure 2In some embodiments, the ventilation device 30 is used to perform at least one function required for mechanical ventilation, including an inspiration maintenance function and an anesthesia function. In some embodiments, the ventilation device 30 includes at least one ventilation function module 31, each ventilation function module 31 being used to perform at least one function required for mechanical ventilation; the at least one function includes an inspiration maintenance function and an anesthesia function.

[0139] The ventilation function module 31 will be explained below in conjunction with the specific functions implemented by the ventilation equipment.

[0140] In some embodiments, the ventilation device 30 may be a ventilation device for anesthesia, such as an anesthesia machine, which is primarily used to provide anesthetic gas, deliver the anesthetic gas to the animal's respiratory system (e.g., lungs), and control the amount of anesthetic gas inhaled. Please refer to... Figure 3 and Figure 4 These are some examples of ventilation devices. In some embodiments, the ventilation device 30 may include an air source interface 312, a breathing assist device 320, an anesthetic delivery device 330, and a breathing circuit 340; in some embodiments, the anesthesia machine may also include a breathing interface 311.

[0141] The gas source interface 312 is used to connect to a gas source (not shown in the figure) to provide gas. This gas can typically be oxygen, nitrous oxide (laughing gas), or air. In some embodiments, the gas source can be a compressed gas cylinder or a central gas supply source, supplying gas to the anesthesia machine through the gas source interface 312. The supplied gas types include oxygen, nitrous oxide, and air. In some embodiments, the gas source can be an external gas source; in some embodiments, a gas source can also be installed inside the ventilation equipment. The gas source interface 312 can include conventional components such as a pressure gauge, pressure regulator, flow meter, pressure reducing valve, and N2O-O2 proportional control protection device, used to control the flow rate of various gases (e.g., oxygen, nitrous oxide, and air). The gas input into the gas source interface 312 enters the breathing circuit 340 and mixes with the existing gas in the breathing circuit 340 to form a gas mixture.

[0142] The anesthetic delivery device 330 is used to provide anesthetic drugs, for example, to provide a gas mixed with anesthetic drugs. Typically, the anesthetic drug is mixed in gaseous form with fresh air introduced through the gas source interface 312 and delivered together into the breathing circuit. In one specific embodiment, the anesthetic delivery device 330 is implemented using an anesthetic vaporizer. The anesthetic drug is typically liquid and stored in the vaporizer. Optionally, the vaporizer may include a heating device for heating the anesthetic drug to volatilize it, generating anesthetic vapor. The anesthetic delivery device 330 is connected to the conduit of the gas source interface 312, and the anesthetic vapor mixes with the fresh air introduced through the gas source interface 312 before being delivered together into the breathing circuit.

[0143] The breathing circuit 340 is used to connect the gas source interface 312 to the respiratory system of the target object, such as an animal, so as to input a preset gas to the target object and discharge part of the gas exhaled by the target object to the external environment; wherein, the preset gas is the gas provided by the gas source and the gas mixed with anesthetic output device 330.

[0144] In some embodiments, the breathing circuit 340 may include an inspiratory branch 340b, an expiratory branch 340a, and a soda lime container 340c. The inspiratory branch 340b and the expiratory branch 340a are connected to form a closed loop, and the soda lime container 340c is disposed on the pipeline of the expiratory branch 340a. A mixture of fresh air introduced by the air source interface 312 is input through the inlet of the inspiratory branch 340b and provided to the target through a breathing interface 311 disposed at the outlet of the inspiratory branch 340b. The breathing interface 311 may be a face mask, a nasal cannula, or an endotracheal tube. In a preferred embodiment, a one-way valve is provided on the inspiratory branch 340b, which opens during the inspiratory phase and closes during the expiratory phase. A one-way valve is also provided on the expiratory branch 340a, which closes during the inspiratory phase and opens during the expiratory phase. The inlet of the exhalation branch 340a is connected to the breathing interface 311. When the animal exhales, the exhaled gas enters the soda lime container 340c through the exhalation branch 340a. The carbon dioxide in the exhaled gas is filtered out by the substance in the soda lime container 340c. The gas after the carbon dioxide is filtered out is then recirculated into the inhalation branch 340b.

[0145] The respiratory assist device 320 provides power to supply a preset gas to the target object or to expel a portion of the gas exhaled by the target object into the external environment. In some embodiments, the respiratory assist device 320 provides power for the animal's involuntary breathing, maintaining airway patency. In some embodiments, the respiratory assist device 320 is connected to the gas source interface 312 and the breathing circuit 340, controlling the delivery of gas supplied by the gas source to the target object, such as an animal, through the breathing circuit 340. In some specific embodiments, the respiratory assist device 320 mixes fresh gas input from the gas source interface 312 with gas exhaled by the target object in the breathing circuit 340 and anesthetic drugs output from the anesthetic output device 330, and outputs the mixture through the inspiratory branch 340b to the breathing interface 311 to drive the animal to inhale, and receives gas exhaled by the target object through the expiratory branch 340a. In specific embodiments, the respiratory assist device 320 typically includes a machine-controlled ventilation module, the airflow channel of which is connected to the breathing circuit. During the maintenance of anesthesia or when the animal has not resumed spontaneous breathing, a machine-controlled ventilation module is used to provide the target subject with the power for breathing.

[0146] The above is a description of the ventilation device 30. It should be noted that the above are just some examples of the ventilation device 30, and are not intended to limit the ventilation device 30 to only having this structure. In the example shown in the figure, the ventilation function module 31 in the ventilation device 30 can be the breathing interface 311, air source interface 312, breathing assist device 320, and anesthetic delivery device 330 mentioned above.

[0147] In some embodiments, the ventilation device 30 has an inspiratory hold function. When the inspiratory hold function is activated, the ventilation device 30 can perform inspiratory hold-related actions to initiate and execute inspiratory hold—for example, delivering air to the animal's lungs and maintaining stable intrapulmonary pressure. During or at this stage of inspiratory hold, the pressure in the animal's lungs is stable, and the lungs are not moving, thereby facilitating radiographic imaging, i.e., image capture by the radiographic imaging device 10. In some embodiments, the ventilation device 30 can be used to anesthetize and maintain inspiratory hold on a target subject, such as an animal.

[0148] In this application, two concepts regarding the ventilation device 30 need to be specifically explained: one is the ventilation maintenance function, and the other is the activation / execution of ventilation maintenance. Under normal circumstances, when the ventilation maintenance function is activated, the relevant actions are immediately executed to activate / execute ventilation maintenance. For example, when the user issues a command to activate ventilation maintenance to the ventilation device, in response to the command, the device activates the ventilation maintenance function and immediately activates / executes ventilation maintenance for the target object. In some embodiments, a delay time is introduced. When the inhalation hold function is activated, the ventilation hold function is activated only after a delay time has elapsed. That is, the ventilation hold-related actions are performed only after a delay time to achieve ventilation hold for the target object. It is understood that the delay time here does not refer to the delay caused by the time required for the transmission of instructions, signals, or commands in the circuit (although this time overhead is negligible), nor does it refer to the delay caused by the time required for components or circuits to process or parse instructions, signals, or commands upon receipt (although this time overhead is negligible). The delay time in this application refers to a deliberately set time, such as the time set by the user through the interactive interface, or the time set for the equipment during the manufacturing process, which will be further explained below.

[0149] In some embodiments, please refer to Figure 5The ventilation function module 31 may include a controller 32. The controller 32 is used to acquire the inspiratory hold delay time and, upon receiving an inspiratory hold function start command, initiates inspiratory hold only after the aforementioned delay time has elapsed. The delay time acquired by the controller 32 may be a factory default setting or a user-set setting. In some embodiments, the controller 32 prohibits the inspiratory hold from being initiated during the aforementioned delay time.

[0150] In some embodiments, please refer to Figure 6 The ventilation function module 31 may include an input module 33; in some embodiments, the input module 33 is used for a user to input an inspiratory hold function activation command. In some embodiments, the input module 33 is used for a user to input a command for setting the inspiratory hold delay time; the controller 32 sets the inspiratory hold delay time based on the command for setting the inspiratory hold delay time. In some embodiments, the input module 33 is used for a user to input a command for setting the duration of the inspiratory hold; the controller 32 sets the duration of the inspiratory hold based on the command for setting the duration of the inspiratory hold.

[0151] The input module 33 can be a keyboard or buttons, or it can be a control on the human-computer interaction interface. The user can input the command to start the inhalation hold function by clicking the control.

[0152] For example, a scenario could be as follows: if the delay time is 10 seconds, after the user issues a command to the ventilation device to perform inspiratory maintenance through input module 33, this command is to the controller 32 to start the inspiratory maintenance function. Therefore, the controller 32 responds to the command and starts timing. After the 10-second delay time, inspiratory maintenance is started again (for example, opening the relevant control valve on the breathing circuit 340 and delivering air to the target to maintain the stability of the target's lung pressure).

[0153] When the ventilation device 10 is preparing to actually start and perform inspiratory maintenance after a delay time, it can also select a better time based on the respiratory cycle of the target subject, and start and perform inspiratory maintenance when the respiratory cycle reaches this time.

[0154] Therefore, in some embodiments, after the aforementioned delay time, the controller 32 also determines in real time whether the respiratory cycle of the target object meets the inspiratory maintenance start condition. If it does, inspiratory maintenance is started again. In some embodiments, when the respiratory cycle of the target object reaches the end of inspiratory phase, the controller 32 determines that the start condition is met. That is, after the aforementioned delay time, when the controller 32 is about to actually start and execute inspiratory maintenance, it first determines the current respiratory state of the target object, and when the target object reaches the end of inspiratory phase, the controller 32 actually starts and executes inspiratory maintenance.

[0155] In some embodiments, the controller 32 also acquires the duration of the inspiratory hold, and stops the inspiratory hold after the duration of the inspiratory hold has elapsed. The duration of the inspiratory hold acquired by the controller 32 may be set by factory default or by user setting.

[0156] The controller 32 can generate relevant prompts during the delay period, and the controller 32 can also generate relevant prompts during the actual execution of the inhalation hold process. Examples are given below.

[0157] In some embodiments, the controller 32 generates a prompt message during the aforementioned delay time. The prompt message may be one or more of the following:

[0158] For example, provide a real-time notification of the elapsed time, such as a timer.

[0159] Prompts regarding the remaining progress of the delay time, such as displaying a countdown in real time to indicate the current remaining time.

[0160] The aforementioned prompts can be text-based, such as displaying the elapsed time, remaining time, or progress via a progress bar on a screen; they can also be sound-based, such as announcing the time or using beeping sounds to remind the user, with a gentler beeping sound in the first half of the delay and a faster beeping sound in the second half, becoming increasingly rapid towards the end; they can also be light-based, for example, using light-emitting components (such as LED indicator lights) on the ventilation device 30 to emit light signals, where different colors of light can represent different meanings, or different flashing frequencies of the LEDs can represent different meanings, such as flashing the LEDs at a slower frequency in the first half of the delay and at a faster frequency in the second half, with the flashing frequency increasing towards the end; the prompts can also be a combination of two or more of the above methods.

[0161] The display screen mentioned in this article can be a display screen installed on the main body of the ventilation equipment 30, which means that the display screen is also located in the shielded room along with the ventilation equipment 30, and the user can view the display screen through the glass window of the shielded room; the display screen can also be the display screen of the host located outside the shielded room.

[0162] In some embodiments, the controller 32 may also generate relevant prompts after inspiratory hold is initiated. For example, after inspiratory hold is initiated, the controller 32 may generate a prompt indicating that inspiratory hold is in progress, and / or a prompt indicating the remaining time of inspiratory hold, and / or a prompt indicating that time of inspiratory hold has elapsed. In some embodiments, the prompts persist for the duration of inspiratory hold.

[0163] Similarly, the prompts can be text-based, such as displaying a message on the screen indicating that an inspiratory hold is in progress, or indicating the duration and / or remaining time of the inspiratory hold; or they can be sound-based, such as announcing the start of an inspiratory hold, announcing the duration and / or remaining time of the inspiratory hold, issuing a beep when entering an inspiratory hold, or using beeps to indicate progress during the inspiratory hold, with a gentle beep in the early stages and a more rapid beep in the later stages, and a beep closer to the end. The more urgent the prompt tone, the more urgent the prompt message; the prompt message can also be based on light signals, such as by emitting light signals through components on the ventilation device 30 that can emit light signals (such as LED indicator lights), different colors of light can represent different meanings, and different flashing frequencies of LEDs can represent different meanings. For example, when entering the inhalation hold phase, the LED light changes from an off state to an on state. In the early stage of the inhalation hold phase, the LED light flashes at a slower frequency, and in the later stage of the inhalation hold phase, it flashes at a faster frequency, and the flashing frequency is faster as it approaches the end; the prompt message can also be a combination of two or more of the above methods.

[0164] In some embodiments, please refer to Figure 7 The ventilation device 30 may have a display interface and display the information on a screen. The display interface may be generated by the controller 32 or other components. The display interface has a parameter display area 21, which displays the parameters monitored by the ventilation device, such as time-varying pressure parameter waveforms, time-varying gas flow parameter waveforms, respiratory rate, tidal volume, positive end-inspiratory pressure, etc. The display interface may also have an operation area 22, which may include controls for setting delay time, controls for setting the duration of inspiratory hold, and controls for activating the inspiratory hold function. The display interface may also have a prompt area 23, which displays one or more of the above-mentioned prompt information. Figure 8 As an example, clicking a specific control on operation area 22 will trigger a pop-up window, through which the user can set the delay time and duration. How to complete operations and settings through the human-computer interaction interface will be explained further below.

[0165] In some embodiments, referring to FIG9(a), the ventilation function module 31 may include an inspiratory hold activation module 42; in some embodiments, the inspiratory hold activation module 42 is used to activate inspiratory hold after a delay time when the inspiratory hold function is activated. In some embodiments, the inspiratory hold activation module 42 prohibits the activation of inspiratory hold during the aforementioned delay time.

[0166] In some embodiments, the delay time is preset. For example, the delay time is set by the manufacturer at the time of shipment.

[0167] In some embodiments, the delay time can also be set and modified by the user.

[0168] In some embodiments, referring to FIG9(b), the ventilation function module 31 may include a first time setting module 41 and an inspiratory hold activation module 42. In some embodiments, the first time setting module 41 is used to set a delay time for delaying the activation of inspiratory hold; the inspiratory hold activation module 42 is used to acquire the aforementioned delay time and, when the inspiratory hold function is activated, activate inspiratory hold only after the aforementioned delay time has elapsed. In some embodiments, the inspiratory hold activation module 42 prohibits the activation of inspiratory hold during the aforementioned delay time.

[0169] As can be seen, in some embodiments, the delay time can be set by the manufacturer when the ventilation equipment leaves the factory, or it can be set and modified by the user according to the actual situation.

[0170] The explanation continues below.

[0171] When the ventilation device 10 is preparing to actually start and perform inspiratory maintenance after a delay time, it can also select a better time based on the respiratory cycle of the target subject, and start and perform inspiratory maintenance when the respiratory cycle reaches this time.

[0172] Therefore, in some embodiments, after the aforementioned delay time, the inspiratory hold activation module 42 also determines in real time whether the respiratory cycle of the target object meets the activation conditions for inspiratory hold. If it does, inspiratory hold is activated again. In some embodiments, when the respiratory cycle of the target object reaches the end of inspiratory phase, the inspiratory hold activation module 42 determines that the activation conditions are met. That is, after the aforementioned delay time, when the inspiratory hold activation module 42 is ready to actually activate and execute inspiratory hold, it first determines the current respiratory state of the target object, and when the target object reaches the end of inspiratory phase, the inspiratory hold activation module 42 actually activates and executes inspiratory hold.

[0173] In some embodiments, please refer to Figure 10The ventilation function module 31 may also include a second time setting module 43, which is used to set the duration of the inspiratory hold; the inspiratory hold start module 42 is used to stop the inspiratory hold after the duration of the inspiratory hold is reached.

[0174] The aforementioned delay time can be set by the factory default or by the user; similarly, the aforementioned duration can be set by the factory default or by the user; for example, in some embodiments, the first time setting module 41 and the second time setting module 43 can be, for example... Figure 7 The controls in the central operation area 22.

[0175] In some embodiments, please refer to Figure 11 The ventilation function module 31 may also include a prompting module 44. The prompting module 44 can generate relevant prompting information during the delay time, and it can also generate relevant prompting information during the actual execution of the inspiratory maintenance process, as illustrated below.

[0176] In some embodiments, the prompting module 44 generates a prompt message during the aforementioned delay time. The prompt message may be one or more of the following:

[0177] For example, provide a real-time notification of the elapsed time, such as a timer.

[0178] Prompts regarding the remaining progress of the delay time, such as displaying a countdown in real time to indicate the current remaining time.

[0179] The aforementioned prompts can be text-based, such as displaying the elapsed time, remaining time, or progress via a progress bar on a screen; they can also be sound-based, such as announcing the time or using beeping sounds to remind the user, with a gentler beeping sound in the first half of the delay and a faster beeping sound in the second half, becoming increasingly rapid towards the end; they can also be light-based, for example, using light-emitting components (such as LED indicator lights) on the ventilation device 30 to emit light signals, where different colors of light can represent different meanings, or different flashing frequencies of the LEDs can represent different meanings, such as flashing the LEDs at a slower frequency in the first half of the delay and at a faster frequency in the second half, with the flashing frequency increasing towards the end; the prompts can also be a combination of two or more of the above methods.

[0180] In some embodiments, the prompting module 44 may also generate relevant prompting information after inhalation hold is initiated. For example, after inhalation hold is initiated, the prompting module 44 may generate a prompting message indicating that inhalation hold is in progress, and / or a prompting message indicating the remaining time of inhalation hold, and / or a prompting message indicating that time of inhalation hold has elapsed. In some embodiments, the prompting information persists for the duration of inhalation hold.

[0181] Similarly, the prompts can be text-based, such as displaying a message on the screen indicating that an inspiratory hold is in progress, or indicating the duration and / or remaining time of the inspiratory hold; or they can be sound-based, such as announcing the start of an inspiratory hold, announcing the duration and / or remaining time of the inspiratory hold, issuing a beep when entering an inspiratory hold, or using beeps to indicate progress during the inspiratory hold, with a gentle beep in the early stages and a more rapid beep in the later stages, and a beep closer to the end. The more urgent the prompt tone, the more urgent the prompt message; the prompt message can also be based on light signals, such as by emitting light signals through components on the ventilation device 30 that can emit light signals (such as LED indicator lights), different colors of light can represent different meanings, and different flashing frequencies of LEDs can represent different meanings. For example, when entering the inhalation hold phase, the LED light changes from an off state to an on state. In the early stage of the inhalation hold phase, the LED light flashes at a slower frequency, and in the later stage of the inhalation hold phase, it flashes at a faster frequency, and the flashing frequency is faster as it approaches the end; the prompt message can also be a combination of two or more of the above methods.

[0182] In some embodiments, please refer to Figure 12 The ventilation function module 31 may include a human-computer interaction module 50, which will be described in detail below.

[0183] As described above, in some embodiments, the ventilation device 30 activates the inspiratory hold function after a delay period when the inspiratory hold function is activated.

[0184] In some embodiments, the delay time is preset. For example, the delay time is set by the manufacturer at the time of shipment.

[0185] In some embodiments, the delay time can also be set and modified by the user.

[0186] For example, the human-computer interaction module 50 has an interactive interface for human-computer interaction. The human-computer interaction module 50 may be composed of a display screen and physical operation buttons, or it may be a touch screen.

[0187] In some embodiments, the human-computer interaction module includes a setting key 51 for inspiratory hold, which can be a physical key or a virtual key on the interactive interface. The setting key 51 is used by the user to set a delay time for delaying the activation of inspiratory hold; when the inspiratory hold function is activated, the ventilation device 30 prohibits the activation of inspiratory hold during the aforementioned delay time, and activates inspiratory hold again after the aforementioned delay time has elapsed.

[0188] In some embodiments, the human-computer interaction module 50 generates and displays a first interface, which displays a setting button 51; in some embodiments, in response to a click on the setting button 51, the human-computer interaction module 50 generates and displays a second interface—the second interface may be, for example, a pop-up window; in some embodiments, the second interface includes a delay time setting control 52 and / or an inhalation hold duration setting control 53—for example… Figure 13 This is just one example. The user can set the delay time using setting control 52. The user can set the duration of the inspiratory hold using setting control 53. In some embodiments, the human-computer interaction module 50 is used to stop the inspiratory hold after the duration of the inspiratory hold has elapsed.

[0189] As can be seen, in some embodiments, the delay time can be set by the manufacturer when the ventilation equipment leaves the factory, or it can be set and modified by the user according to the actual situation.

[0190] The explanation continues below.

[0191] In some embodiments, the human-computer interaction module 50 has an inhalation hold state display mode. In some embodiments, in the inhalation hold state display mode, the human-computer interaction module 50 can display at least one of the following:

[0192] A message indicating the remaining or elapsed time of the delay;

[0193] A prompt message indicating whether to enter the inspiratory hold phase;

[0194] A message indicating that an inspiratory hold is in progress;

[0195] A message indicating the remaining time for inhalation;

[0196] A message indicating when to hold your breath for an extended period of time;

[0197] The message indicating the end of the inhalation hold.

[0198] In some embodiments, information such as prompts indicating that an inspiratory hold is in progress, prompts indicating the remaining time of the inspiratory hold, and prompts indicating that the inspiratory hold time has elapsed can persist for the duration of the inspiratory hold.

[0199] In some embodiments, the information displayed by the human-computer interaction module 50 may be graphic or text-based prompts, etc.

[0200] In one embodiment, please refer to Figure 14 The human-computer interaction module 50 displays a start button 54 on the display interface. When the user clicks the start button 54, it issues a command to start the inspiratory hold function. When the inspiratory hold function is started, the ventilation device 30 prevents the inspiratory hold function from starting for a delay period, and then starts the inspiratory hold function again after the aforementioned delay period has elapsed. During this process, the start button 54 can also be used to display prompt information, such as displaying the remaining or elapsed time of the delay period on the start button 54. After the inspiratory hold function is started, the start button 54 displays a prompt that inspiratory hold is in progress.

[0201] In some embodiments, the human-machine interface module 50 can enter the inspiratory hold status display mode in response to an inspiratory hold function activation command, wherein the inspiratory hold function activation command is used to activate the inspiratory hold function. Therefore, when the ventilation device 30 receives the inspiratory hold function activation command, on the one hand, the human-machine interface module 50 enters the inspiratory hold status display mode, and on the other hand, the ventilation device 30 starts timing and activates inspiratory hold after a delay time.

[0202] In some embodiments, after confirming that the user has set the delay time and / or duration, the human-computer interaction module 50 enters the inhalation hold state display mode. For example, when the user clicks... Figure 13 If the checkmark in the upper right corner of the pop-up window indicates that the user has completed setting the delay time and / or duration.

[0203] In the scheme of this application, after the user activates the inspiratory hold function, the ventilation device 30 will activate the inspiratory hold function again after a certain delay. During this delay, the user has time to leave the shielded room. After the ventilation device activates the inspiratory hold function outside the shielded room, the user can then activate the radiometric imaging device 10 to photograph the target object. To make the operation more convenient for the user, the ventilation device 30 can also provide prompts during the activation and process of the inspiratory hold function, so that the user can understand whether the ventilation device 30 has entered the inspiratory hold function and its specific working status, thereby making it easier for the user to decide when to activate the radiometric imaging device 10 to take pictures.

[0204] Some embodiments also disclose an inspiratory sustaining start-up method for a ventilation device, which can be any of the ventilation devices described in any of the embodiments herein. Please refer to... Figure 15 Some embodiments of the inhalation-holding start method include the following steps:

[0205] Step S100: Obtain the delay time for delayed inhalation hold;

[0206] Step S110: Upon receiving the command to activate the inspiratory hold function, inspiratory hold is activated after the aforementioned delay time. In some embodiments, step S110 prevents inspiratory hold from activating during the delay time. In some embodiments, step S110 stops inspiratory hold after the duration of inspiratory hold has elapsed.

[0207] In some embodiments, after a delay, step S110 further determines in real time whether the respiratory cycle of the target object meets the initiation conditions for inspiratory maintenance. If it does, inspiratory maintenance is then initiated. In some embodiments, the initiation conditions are determined to be met when the respiratory cycle of the target object reaches the end of inspiration.

[0208] In some embodiments, please refer to Figure 16 The inspiratory hold initiation method further includes step S120: generating a prompt message. For example, after inspiratory hold is initiated, step S120 generates a prompt message indicating that inspiratory hold is in progress; another example is that step S120 generates a prompt message indicating the remaining inspiratory hold time; yet another example is that step S120 generates a prompt message indicating that inspiratory hold time has elapsed. In some embodiments, the prompt message persists for the duration of inspiratory hold.

[0209] The aforementioned delay time and / or duration can be preset, for example, set by the manufacturer at the time of shipment.

[0210] The aforementioned delay time and / or duration can also be set via an interface. For example, an interface for setting the delay time could be displayed; user actions based on this interface could be received to set the delay time. Similarly, an interface for setting the duration could be displayed; user actions based on this interface could be received to set the duration.

[0211] Some embodiments of this application also disclose a central station 90, please refer to Figure 17The central station 90 includes a processor 91 and a communication module 92. The communication module 92 is used to establish a communication connection with the ventilation device 30. When the processor 91 receives a user's command to start the inhalation hold function, it sends an instruction to the ventilation device 30 through the communication module 92, so that the ventilation device 30 starts the inhalation hold function after a preset delay time. Understandably, this delay time does not refer to the delay caused by the time required for the transmission of instructions, signals, or commands in the circuit (although this time overhead is negligible), nor does it refer to the delay caused by the time required for components or circuits to process or parse instructions, signals, or commands upon receipt (although this time overhead is negligible). The delay time in this application refers to a deliberately set time, such as the time set by the user through an interactive interface, or the time set for the equipment during the manufacturing process.

[0212] In some embodiments, the processor 91 sets the delay time in response to a command for setting a delay time for inhalation hold.

[0213] In some embodiments, in response to a command to set the duration of inspiratory hold, processor 91 sets the duration after the ventilation device 30 initiates the inspiratory hold.

[0214] In some embodiments, after the ventilation device 30 initiates inspiratory hold, the processor 91 generates a prompt message indicating that inspiratory hold is in progress, and / or a prompt message indicating the remaining time of inspiratory hold, and / or a prompt message indicating that inspiratory hold time has elapsed. In some embodiments, the prompt message persists for the duration of inspiratory hold.
