Description

A ventilation device for anesthesia and its inspiration hold starting method and central station Technical Field

[0001] The present invention relates to a ventilation device for anesthesia and an inspiration holding starting method and a central station thereof. Background Art

[0002] With the development of the economy and the improvement of people's living standards, more and more people are keeping pets, the number of pet hospitals is increasing, and the specialization of pet diagnosis and treatment is becoming more and more specialized. When an animal has problems such as inflammation or tumors in the lungs, a chest X-ray is required.

[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 facilitating the display of lung tissue and lesions; at the same time, it is also required to hold the breath at the end of inspiration to avoid motion blur caused by breathing.

[0004] While human patients listen to doctors' verbal instructions to breathe in, hold their breath, and exhale during chest imaging, animal patients are unable to understand and follow these instructions.

[0005] Therefore, it is difficult to take chest X-rays on animals. Technical issues

[0124] The present invention will be further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions, and for those skilled in the art, it is not necessary to describe these related operations in detail. They will fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0125] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0126] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0127] In one approach, anesthetize an animal intravenously. A user (e.g., a doctor) then places the anesthetized animal on the surface of a radiological imaging device (e.g., an X-ray machine, DR device, or CT scanner). After positioning the animal, the user observes its breathing and activates the radiological imaging device to capture an image the instant the animal inhales. This approach requires the user to observe the animal's breathing. Furthermore, the animal is still breathing during the capture process, meaning its lungs are still moving. This can result in blurred images and unclear lung fields, necessitating continuous capture and a low success rate.

[0128] In one approach, a user (e.g., a doctor) connects an animal to an anesthesia machine next to the radioactive imaging device in a shielded room. They operate the machine to deliver anesthetic gas to the animal and maintain the patient's breath. They then operate the hand or foot switch on the radioactive imaging device to initiate exposure and image formation. Afterward, they operate the machine again to stop the breath-hold. While this approach ensures image quality, it exposes the doctor to radiation, which can be detrimental to their health over the long term.

[0129] In one solution, some manufacturers equip the anesthesia machine with a remote control device, which allows the doctor to start the inhalation hold of the anesthesia machine outside the shielded room, thereby protecting the doctor from radiation exposure from the radioactive imaging equipment; some manufacturers establish communication between the anesthesia machine and the radioactive imaging equipment, so that the anesthesia machine and the radioactive imaging equipment can cooperate to achieve inhalation hold while shooting. For example, when the anesthesia machine is performing inhalation hold on the animal, the anesthesia machine automatically notifies the radioactive imaging equipment to start exposure to form an image; however, these solutions not only cause complex design and increased costs, but also have poor compatibility with equipment of other brands, so there are many disadvantages.

[0130] The present application proposes a ventilation device for anesthesia, which can perform inhalation hold on animals; in order to cooperate with the image capture of radioactive imaging equipment, the ventilation device has a delayed start-up function of inhalation hold, that is, when the inhalation hold function of the ventilation device is activated, the ventilation device will perform the inhalation hold action after a preset delay time, so that during this time, the user (such as a doctor) can leave the shielded room; at the same time, the ventilation device can also give some displays about the inhalation hold status to remind (such as how much delay time is left, such as whether the inhalation hold function is in progress) users outside the shielded room, so that the user can start the radioactive imaging device shooting outside the shielded room according to the reminder of the current inhalation hold status, thereby realizing a low-cost radioactive imaging device shooting plan for animals, and has very good brand / model compatibility.

[0131] Please refer to Figure 1, which is an application scenario of the present application. A radioactive imaging device 10 and a ventilation device 30 are placed in a shielded room. The ventilation device 30 can maintain the animal's inhalation to cooperate with the radioactive imaging device 10 to shoot the animal.

[0132] In some embodiments, the radioactive imaging device 10 uses radioactive rays to image the animal. For example, the radioactive imaging device is an X-ray imaging device or a computerized tomography device.

[0133] In some embodiments, the radiological imaging device 10 may also include a remote control terminal. In some embodiments, the remote control terminal is located a certain distance from the main body of the radiological imaging device 10 to facilitate remote operation by the user. For example, as described above, the main body of the radiological imaging device 10 is placed inside a shielded room, while the remote control terminal is located outside. The user can trigger the radiological imaging device 10 to operate, such as starting an image, by issuing instructions / commands to the remote control terminal, such as by pressing a button.

[0134] Referring to FIG. 2 , in some embodiments, a ventilation device 30 is configured to perform at least one function required for mechanical ventilation, including an inspiratory hold function and an anesthesia function. In some embodiments, the ventilation device 30 includes at least one ventilation function module 31 , each of which is configured to perform at least one function required for mechanical ventilation, including an inspiratory hold function and an anesthesia function.

[0135] The ventilation function module 31 is described below in conjunction with the specific functions implemented by the ventilation device.

[0136] In some embodiments, the ventilation device 30 may be a ventilation device used for anesthesia, such as an anesthesia machine. This machine primarily provides anesthetic gas, delivers it to the animal's respiratory system (e.g., lungs), and controls the amount of anesthetic gas inhaled. Please refer to Figures 3 and 4 for some examples of ventilation devices. In some embodiments, the ventilation device 30 may include a gas source interface 312, a respiratory assistance device 320, an anesthetic delivery device 330, and a breathing circuit 340. In some embodiments, the anesthesia machine may also include a respiratory interface 311.

[0137] The gas source interface 312 is used to connect to a gas source (not shown) that provides gas. This gas can typically be oxygen, nitrous oxide (nitrous oxide), or air. In some embodiments, the gas source can be a compressed gas cylinder or a central gas supply, supplying oxygen, nitrous oxide, or air to the anesthesia machine through the gas source interface 312. The gas supplied can be oxygen, nitrous oxide, or air. In some embodiments, the gas source can be an external source; in some embodiments, the gas source can also be internal to the ventilation device. The gas source interface 312 can include conventional components such as a pressure gauge, pressure regulator, flow meter, pressure reducing valve, and N2O-O2 ratio control and protection device to control the flow of various gases (e.g., oxygen, nitrous oxide, and air). The gas input from the gas source interface 312 enters the breathing circuit 340 and forms a mixed gas with the existing gas in the breathing circuit 340.

[0138] The anesthetic output device 330 is used to provide anesthetic drugs, for example, to provide gas mixed with anesthetic drugs. Normally, the anesthetic drugs are mixed into the fresh air introduced by the gas source interface 312 in the form of gas, and are transported together to the breathing circuit. In a specific embodiment, the anesthetic output device 330 is implemented by an anesthetic vaporizer. Anesthetic drugs are usually liquid and stored in an anesthetic vaporizer. Optionally, the anesthetic vaporizer may include a heating device for heating the anesthetic to volatilize it and generate anesthetic vapor. The anesthetic output device 330 is connected to the pipeline of the gas source interface 312, and the anesthetic vapor is mixed with the fresh air introduced by the gas source interface 312, and then is transported together to the breathing circuit.

[0139] The breathing circuit 340 is used to connect the gas source interface 312 and the respiratory system of a target object, such as an animal, so as to input a preset gas into the target object and discharge part of the gas exhaled by the target object into the external environment; wherein the preset gas is the gas provided by the gas source and the gas mixed with anesthetic output by the anesthetic output device 330.

[0140] In some embodiments, the breathing circuit 340 may include an inspiratory branch 340b, an expiratory branch 340a, and a soda lime tank 340c. The inspiratory branch 340b and the expiratory branch 340a are connected to form a closed circuit, and the soda lime tank 340c is arranged on the pipeline of the expiratory branch 340a. The mixed gas of fresh air introduced by the gas source interface 312 is input through the inlet of the inspiratory branch 340b and provided to the target subject through the breathing interface 311 arranged at the outlet of the inspiratory branch 340b. The breathing interface 311 can be a mask, a nasal cannula, or an endotracheal cannula. In a preferred embodiment, the inspiratory branch 340b is provided with a one-way valve, which opens during the inspiratory phase and closes during the expiratory phase. The expiratory branch 340a is also provided with a one-way valve, 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 tank 340c through the exhalation branch 340a. The carbon dioxide in the exhaled gas is filtered out by the substance in the soda lime tank 340c. The gas after the carbon dioxide is filtered out is recirculated into the inhalation branch 340b.

[0141] The breathing assistance device 320 is used to provide power to input a preset gas to the target subject, or to discharge part of the gas exhaled by the target subject to the external environment. In some embodiments, the breathing assistance device 320 is used to provide power for the animal's non-spontaneous breathing and maintain airway patency. In some embodiments, the breathing assistance device 320 is connected to the gas source interface 312 and the breathing circuit 340 to control the delivery of the gas provided by the gas source to the target subject, such as an animal, through the breathing circuit 340. In some specific embodiments, the breathing assistance device 320 mixes the fresh gas input from the gas source interface 312, the gas exhaled by the target subject in the breathing circuit 340, and the anesthetic drug output from the anesthetic output device 330, and outputs the mixture to the breathing interface 311 through the inspiratory branch 340b to drive the animal to inhale, and receives the gas exhaled by the target subject through the expiratory branch 340a. In a specific embodiment, the breathing assistance device 320 generally includes a machine-controlled ventilation module, and the airflow pipeline of the machine-controlled ventilation module is connected to the breathing circuit. During the anesthesia maintenance phase or when the animal has not recovered spontaneous breathing, a machine-controlled ventilation module is used to provide breathing power for the target subject.

[0142] The above is a description of the ventilation device 30. It should be noted that these are merely examples of the ventilation device 30 and are not intended to limit the ventilation device 30 to a specific structure. In the example shown, the ventilation function module 31 of the ventilation device 30 may include the aforementioned respiratory interface 311, air source interface 312, respiratory assistance device 320, and anesthetic delivery device 330.

[0143] In some embodiments, the ventilation device 30 has an inspiration hold function. Once the inspiration hold function is activated, the ventilation device 30 can perform inspiration hold-related actions to initiate and execute inspiration hold—for example, delivering air to the animal's lungs and maintaining stable intrapulmonary pressure. During inspiration hold, or during this phase, the animal's lung pressure is stable and the lungs are motionless, facilitating radiological imaging, i.e., image capture by the radiological imaging device 10. In some embodiments, the ventilation device 30 can be used to anesthetize and hold an animal's lungs.

[0144] In this application, there are two concepts that need special explanation for the ventilation device 30, one is the ventilation hold function, and the other is starting / executing ventilation hold; under normal circumstances, when the ventilation hold function is turned on, the relevant actions are immediately performed to start / execute ventilation hold - for example, when the user issues a command to start ventilation hold to the ventilation device, in response to the command, the device starts the ventilation hold function and immediately starts / executes ventilation hold for the target object. In some embodiments, a delay time is introduced. When the inhalation hold function is activated, ventilation hold for the target object is activated after the delay time. That is, after the delay time, the actions related to ventilation hold are executed to achieve ventilation hold for the target object. It can be understood that the delay time here does not refer to the delay caused by the fact that instructions, signals, commands, etc. need to spend a certain amount of time in the circuit transmission process (although this time overhead is negligible), nor does it refer to the delay caused by the fact that components or circuits need to spend a certain amount of time (although this time overhead is negligible) to process or parse instructions, signals, commands when receiving them. The delay time in this application refers to a time that is deliberately set, such as the time set by the user through the interactive interface, or the time set for the equipment during the process of manufacturing the equipment in the factory, which will be further explained below.

[0145] In some embodiments, referring to FIG. 5 , the ventilation function module 31 may include a controller 32 configured to obtain a delay time for an inspiratory hold function and, upon receiving an inspiratory hold function activation command, to activate the inspiratory hold function after the delay time has elapsed. The delay time obtained by the controller 32 may be a factory default setting or user-configured. In some embodiments, the controller 32 prohibits initiation of an inspiratory hold function during the delay time.

[0146] In some embodiments, referring to FIG. 6 , the ventilation function module 31 may include an input module 33. In some embodiments, the input module 33 is configured to allow a user to input a command for activating the inhalation hold function. In some embodiments, the input module 33 is configured to allow a user to input a command for setting an inhalation hold delay time. The controller 32 sets the inhalation hold delay time based on the command for setting the inhalation hold delay time. In some embodiments, the input module 33 is configured to allow a user to input a command for setting the duration of the inhalation hold. The controller 32 sets the duration of the inhalation hold based on the command for setting the duration of the inhalation hold.

[0147] The input module 33 may be a keyboard and buttons, etc. The input module 33 may also be a control on a human-computer interaction interface, and the user inputs a start command for the inhalation hold function by clicking on the control.

[0148] For example, a scenario may be as follows: if the delay time is 10 seconds, then after the user issues a command to the ventilation device to perform an inhalation hold through, for example, the input module 33, the command activates the inhalation hold function for the controller 32. Therefore, the controller 32 responds to the command and performs a timing. After the delay time of 10 seconds, the inhalation hold is activated (for example, the relevant control valve on the breathing circuit 340 is opened and air is supplied to the target object to maintain a stable pressure in the target object's lungs).

[0149] When the ventilation device 10 is ready to actually start and perform the inhalation hold after the delay time, it can also select a better time based on the respiratory cycle of the target object, and start and perform the inhalation hold when the respiratory cycle reaches this time.

[0150] Therefore, in some embodiments, after the above-mentioned delay time has passed, the controller 32 also determines in real time whether the target object's breathing cycle meets the start conditions for inhalation hold, and if so, it restarts the inhalation hold; in some embodiments, when the target object's breathing cycle reaches the end of inspiration, the controller 32 determines that the start conditions are met; that is, after the above-mentioned delay time has passed, when the controller 32 is ready to actually start and execute inhalation hold, it first determines the current breathing state of the target object, and when the target object reaches the stage of reaching the end of inspiration, the controller 32 actually starts and executes inhalation hold.

[0151] In some embodiments, the controller 32 further obtains a duration of an inhalation hold, and stops the inhalation hold after the duration of the inhalation hold is reached. The duration of the inhalation hold obtained by the controller 32 may be a factory default setting or may be set by the user.

[0152] The controller 32 may generate relevant prompt information during the delay time, and may also generate relevant prompt information during the actual execution of the inhale hold, as illustrated below.

[0153] In some embodiments, the controller 32 generates a prompt message during the delay period. The prompt message may be one or more of the following:

[0154] Prompts about the progress of the delayed time, such as real-time prompts of the elapsed time in the form of a timer;

[0155] A reminder about the remaining progress of the delay time, such as a real-time reminder of the remaining time in a countdown manner.

[0156] The above-mentioned prompt information can be a prompt information based on graphics and text, such as displaying the time elapsed or the remaining time of the delay time on a display screen, or displaying the progress by displaying a progress bar, etc.; the prompt information can also be a prompt information based on sound, such as announcing the time by sound, or reminding by sound, emitting a relatively slow dripping prompt sound in the first half of the delay time, and emitting a relatively rapid dripping prompt sound in the second half of the delay time, and the prompt sound becomes more rapid as the delay time approaches the end; the prompt information can also be a prompt information based on a light signal, such as a component on the ventilation device 30 that can emit a light signal (such as an LED prompt light, etc.) emitting a light signal to provide a prompt, different colors of light can represent different meanings, and different flashing frequencies of the LED can represent different meanings, for example, the LED light flashes at a slower frequency in the first half of the delay time and flashes at a faster frequency in the second half of the delay time, and the flashing frequency becomes faster as the delay time approaches the end; the prompt information can also be a combination of two or more of the above methods.

[0157] The display screen involved in this article can be a display screen installed on the device body of the ventilation device 30, which means that the display screen is also located in the shielding room with the ventilation device 30, and the user can view the display screen through the glass windows of the shielding room; the display screen can also be a display screen of a host located outside the shielding room.

[0158] In some embodiments, after initiating an inhale hold, the controller 32 may also generate relevant prompt information. For example, after initiating an inhale hold, the controller 32 may generate a prompt indicating that an inhale hold is in progress, and / or a prompt indicating the remaining inhale hold time, and / or a prompt indicating the elapsed inhale hold time. In some embodiments, the prompt information persists for the duration of the inhale hold.

[0159] Similarly, the prompt information can be a graphic-based prompt information, such as displaying a prompt that an inhalation hold is in progress on the display screen, and displaying a prompt of the elapsed and / or remaining time of the inhalation hold; the prompt information can also be a sound-based prompt information, such as broadcasting the current inhalation hold by sound, broadcasting the elapsed and / or remaining time of the inhalation hold by sound, for example, issuing a prompt sound when entering the inhalation hold, and for example, issuing a prompt sound to indicate the progress during the inhalation hold, emitting a relatively soothing dripping prompt sound in the early stage of the inhalation hold, emitting a relatively rapid dripping prompt sound in the later stage of the inhalation hold, and emitting a relatively slow dripping prompt sound as the end approaches. The prompt sound is more urgent; the prompt information can also be prompt information based on light signals, for example, a component on the ventilation device 30 that can emit light signals (such as an LED prompt light, etc.) emits a light signal to provide a prompt, different colors of light can represent different meanings, and different flashing frequencies of the LED can represent different meanings. For example, when entering the inspiratory hold, the LED light changes from an off state to a lit state. In the early stage of the inspiratory hold, the LED light flashes at a slower frequency, and in the later stage of the inspiratory hold, it flashes at a faster frequency, and the closer to the end of the stage, the faster the flashing frequency; the prompt information can also be a combination of two or more of the above methods.

[0160] In some embodiments, as shown in FIG7 , the ventilation device 30 may have a display interface displayed via a display screen. The display interface may be generated by a controller 32 or other component. The display interface includes a parameter display area 21, which displays 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, and so on. The display interface may also include an operation area 22, which may contain controls for setting delay time, setting the duration of an inspiratory hold, or activating the inspiratory hold function. The display interface may also include a prompt area 23, which displays one or more of the aforementioned prompts. FIG8 shows an example. Clicking a specific control in the operation area 22 will cause a pop-up window to appear, allowing the user to set the delay time and duration. How to complete operations and settings through the human-computer interaction interface will be explained below.

[0161] In some embodiments, referring to FIG. 9( a ), the ventilation function module 31 may include an inhalation hold activation module 42 . In some embodiments, the inhalation hold activation module 42 is configured to, when the inhalation hold function is activated, activate the inhalation hold after a delay period. In some embodiments, the inhalation hold activation module 42 prohibits inhalation hold activation during the delay period.

[0162] In some embodiments, the delay time is pre-set, for example, the delay time is set by the manufacturer before shipment.

[0163] In some embodiments, the delay time can also be set and modified by the user.

[0164] In some embodiments, referring to FIG. 9( b ), the ventilation function module 31 may include a first time setting module 41 and an inhalation hold activation module 42. In some embodiments, the first time setting module 41 is used to set a delay time for delaying the inhalation hold activation; the inhalation hold activation module 42 is used to obtain the delay time and, when the inhalation hold function is activated, activate the inhalation hold after the delay time has elapsed. In some embodiments, the inhalation hold activation module 42 prohibits the inhalation hold from being activated during the delay time.

[0165] It can be seen that in some embodiments, the delay time may be set by the manufacturer when the ventilation device leaves the factory, or may be set and modified by the user according to actual conditions.

[0166] The following explanation continues.

[0167] When the ventilation device 10 is ready to actually start and perform the inhalation hold after the delay time, it can also select a better time based on the respiratory cycle of the target object, and start and perform the inhalation hold when the respiratory cycle reaches this time.

[0168] Therefore, in some embodiments, after the above-mentioned delay time has passed, the inhalation hold starting module 42 also determines in real time whether the target subject's breathing cycle meets the starting conditions for inhalation hold, and if so, it starts the inhalation hold again; in some embodiments, when the target subject's breathing cycle reaches the end of inspiration, the inhalation hold starting module 42 determines that the starting conditions are met; that is, after the above-mentioned delay time has passed, when the inhalation hold starting module 42 is ready to actually start and execute the inhalation hold, it first determines the current breathing state of the target subject, and when the target subject reaches the stage of reaching the end of inspiration, the inhalation hold starting module 42 actually starts and executes the inhalation hold.

[0169] In some embodiments, referring to FIG. 10 , the ventilation function module 31 may further include a second time setting module 43 for setting the duration of the inspiratory hold; and an inspiratory hold start module 42 for stopping the inspiratory hold after the duration of the inspiratory hold is reached.

[0170] The above-mentioned delay time can be set by factory default or set by the user; similarly, the above-mentioned duration can be set by factory default or set by the user; for example, in some embodiments, the first time setting module 41 and the second time setting module 43 can be controls in the operation area 22 in Figure 7.

[0171] In some embodiments, referring to FIG11 , the ventilation function module 31 may further include a prompt module 44. The prompt module 44 may generate relevant prompt information during the delay time, and may also generate relevant prompt information during the actual execution of the inspiration hold, as illustrated below.

[0172] In some embodiments, the prompt module 44 generates prompt information during the delay period. The prompt information may be one or more of the following:

[0173] Prompts about the progress of the delayed time, such as real-time prompts of the elapsed time in the form of a timer;

[0174] A reminder about the remaining progress of the delay time, such as a real-time reminder of the remaining time in a countdown manner.

[0175] The above-mentioned prompt information can be a prompt information based on graphics and text, such as displaying the time elapsed or the remaining time of the delay time on a display screen, or displaying the progress by displaying a progress bar, etc.; the prompt information can also be a prompt information based on sound, such as announcing the time by sound, or reminding by sound, emitting a relatively slow dripping prompt sound in the first half of the delay time, and emitting a relatively rapid dripping prompt sound in the second half of the delay time, and the prompt sound becomes more rapid as the delay time approaches the end; the prompt information can also be a prompt information based on a light signal, such as a component on the ventilation device 30 that can emit a light signal (such as an LED prompt light, etc.) emitting a light signal to provide a prompt, different colors of light can represent different meanings, and different flashing frequencies of the LED can represent different meanings, for example, the LED light flashes at a slower frequency in the first half of the delay time and flashes at a faster frequency in the second half of the delay time, and the flashing frequency becomes faster as the delay time approaches the end; the prompt information can also be a combination of two or more of the above methods.

[0176] In some embodiments, prompt module 44 may also generate relevant prompt information after initiating an inhale hold. For example, prompt module 44 may generate prompt information indicating that an inhale hold is in progress, and / or prompt information indicating the remaining inhale hold time, and / or prompt information indicating the elapsed inhale hold time. In some embodiments, the prompt information persists for the duration of the inhale hold.

[0177] Similarly, the prompt information can be a graphic-based prompt information, such as displaying a prompt that an inhalation hold is in progress on the display screen, and displaying a prompt of the elapsed and / or remaining time of the inhalation hold; the prompt information can also be a sound-based prompt information, such as broadcasting the current inhalation hold by sound, broadcasting the elapsed and / or remaining time of the inhalation hold by sound, for example, issuing a prompt sound when entering the inhalation hold, and for example, issuing a prompt sound to indicate the progress during the inhalation hold, emitting a relatively soothing dripping prompt sound in the early stage of the inhalation hold, emitting a relatively rapid dripping prompt sound in the later stage of the inhalation hold, and emitting a relatively slow dripping prompt sound as the end approaches. The prompt sound is more urgent; the prompt information can also be prompt information based on light signals, for example, a component on the ventilation device 30 that can emit light signals (such as an LED prompt light, etc.) emits a light signal to provide a prompt, different colors of light can represent different meanings, and different flashing frequencies of the LED can represent different meanings. For example, when entering the inspiratory hold, the LED light changes from an off state to a lit state. In the early stage of the inspiratory hold, the LED light flashes at a slower frequency, and in the later stage of the inspiratory hold, it flashes at a faster frequency, and the closer to the end of the stage, the faster the flashing frequency; the prompt information can also be a combination of two or more of the above methods.

[0178] In some embodiments, referring to FIG. 12 , the ventilation function module 31 may include a human-computer interaction module 50 , which will be described in detail below.

[0179] As described above, in some embodiments, when the breath hold function is activated, the ventilation device 30 activates the breath hold function after a delay time.

[0180] In some embodiments, the delay time is pre-set, for example, the delay time is set by the manufacturer before shipment.

[0181] In some embodiments, the delay time can also be set and modified by the user.

[0182] 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, etc. The human-computer interaction module 50 may also be a touch-sensitive display screen, etc.

[0183] In some embodiments, the human-computer interaction module includes an inspiratory hold setting key 51, which can be a physical key or a virtual key on the interactive interface. Setting key 51 allows the user to set a delay time for delaying the inspiratory hold. When the inspiratory hold function is activated, the ventilation device 30 prohibits inspiratory hold activation during the delay time and then activates inspiratory hold after the delay time has elapsed.

[0184] In some embodiments, the human-computer interaction module 50 generates and displays a first interface, which includes a settings button 51. In some embodiments, in response to clicking the settings button 51, the human-computer interaction module 50 generates and displays a second interface, which can 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, as shown in Figure 13. The user can set the delay time using the settings control 52. The user can set the inhalation hold duration using the settings control 53. In some embodiments, the human-computer interaction module 50 is configured to terminate the inhalation hold after the inhalation hold duration has expired.

[0185] It can be seen that in some embodiments, the delay time may be set by the manufacturer when the ventilation device leaves the factory, or may be set and modified by the user according to actual conditions.

[0186] The following explanation continues.

[0187] 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:

[0188] Prompt information of the remaining or elapsed delay time;

[0189] Whether to enter the inhalation hold prompt;

[0190] A reminder message indicating that inspiration hold is in progress;

[0191] Inhale and hold remaining time prompt information;

[0192] Inhale and hold elapsed time prompt information;

[0193] A reminder message indicating that the inhalation hold has ended.

[0194] In some embodiments, information such as prompt information that an inhalation hold is in progress, prompt information of the remaining inhalation hold time, and prompt information of the elapsed inhalation hold time may persist for the duration of the inhalation hold.

[0195] In some embodiments, the information displayed by the human-computer interaction module 50 may be prompt information based on graphics and texts.

[0196] In one embodiment, referring to FIG. 14 , the human-computer interaction module 50 displays a start button 54 on the display interface. When the user clicks the start button 54 , a command to start the inhalation hold function is issued. When the inhalation hold function is activated, the ventilation device 30 prohibits starting the inhalation hold within the delay time, and restarts the inhalation hold after the delay time has passed. During this process, the start button 54 can also be used to display prompt information. For example, during the delay time, a prompt information of the remaining or elapsed delay time is displayed on the start button 54. After the inhalation hold is activated, a prompt information that the inhalation hold is in progress is displayed on the start button 54.

[0197] In some embodiments, the human-computer interaction module 50 can enter the inhalation hold state display mode in response to an inhalation hold function activation command, wherein the inhalation hold function activation command is used to activate the inhalation hold function. Therefore, when the ventilation device 30 receives the inhalation hold function activation command, the human-computer interaction module 50 enters the inhalation hold state display mode and the ventilation device 30 starts timing and activates the inhalation hold after a delay time.

[0198] In some embodiments, upon 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 the check mark in the upper right corner of the pop-up window in FIG. 13 , it indicates that the user has set the delay time and / or duration.

[0199] In the solution of the present application, after the user activates the inhale hold function, the ventilation device 30 will delay for a period of time before initiating the inhale hold. During this delay, the user has time to leave the shielded room and wait outside the shielded room for the ventilation device to activate the inhale hold function before activating the radioactive imaging device 10 to capture the target object. To further facilitate user operation, the ventilation device 30 can also provide prompt information during the activation and operation of the inhale hold function to help the user understand whether the ventilation device 30 is currently in the inhale hold function and its specific operating status, thereby helping the user decide when to activate the radioactive imaging device 10 to capture the target object.

[0200] Some embodiments also disclose a method for activating an inhale-hold breath for a ventilation device, and the ventilation device may be any of the ventilation devices described in this document. Referring to FIG. 15 , the inhale-hold breath activation method of some embodiments includes the following steps:

[0201] Step S100: Obtaining the delay time of delayed start of inhalation hold;

[0202] Step S110: Upon receiving the inhale hold function activation command, the inhale hold is activated after the aforementioned delay time. In some embodiments, step S110 prohibits activation of the inhale hold during the delay time. In some embodiments, step S110 stops the inhale hold after the inhale hold duration has expired.

[0203] In some embodiments, after the delay time, step S110 further determines in real time whether the target subject's breathing cycle meets the initiation condition for inhalation hold. If so, inhalation hold is re-initiated. In some embodiments, the initiation condition is determined to be met when the target subject's breathing cycle reaches the end of inhalation.

[0204] In some embodiments, referring to FIG. 16 , the method for initiating an inhalation hold further includes step S120: generating a prompt. For example, after initiating an inhalation hold, step S120 generates a prompt indicating that an inhalation hold is in progress. In another example, step S120 generates a prompt indicating the remaining inhalation hold time. In another example, step S120 generates a prompt indicating the elapsed inhalation hold time. In some embodiments, the prompt persists for the duration of the inhalation hold.

[0205] The delay time and / or duration mentioned above may be preset, for example, set by the manufacturer before shipment.

[0206] The delay time and / or duration mentioned above may also be configured through an interface. For example, an interface for configuring the delay time may be displayed, and a user operation based on the interface may be received to configure the delay time. Another example may be an interface for configuring the duration time may be displayed, and a user operation based on the interface may be received to configure the duration.

[0207] Some embodiments of the present application also disclose a central station 90. Referring to FIG. 17 , the central station 90 includes a processor 91 and a communication module 92. The communication module 92 is configured to establish a communication connection with the ventilation device 30. Upon receiving a user-initiated command to activate the inhale hold function, the processor 91 issues a command to the ventilation device 30 via the communication module 92, causing the ventilation device 30 to activate the inhale hold function after a preset delay time. It should be understood that the delay time herein does not refer to the delay caused by the time required for the transmission of instructions, signals, commands, etc. through a circuit (although such time overhead is negligible), nor does it refer to the delay caused by the time required for a component or circuit to process or interpret instructions, signals, or commands upon receipt (although such time overhead is negligible). The delay time herein refers to a deliberately set time, such as a time set by a user through an interactive interface, or a time set for the device during the manufacturing process.

[0208] In some embodiments, in response to a command for setting a delay time for an inhalation hold, processor 91 sets the delay time.

[0209] In some embodiments, in response to a command to set the duration of an inspiratory hold, processor 91 sets the duration of time after ventilation device 30 initiates the inspiratory hold.

[0210] In some embodiments, after the ventilation device 30 initiates an inspiratory hold, the processor 91 generates a prompt indicating that an inspiratory hold is in progress, and / or a prompt indicating the remaining inspiratory hold time, and / or a prompt indicating the elapsed inspiratory hold time. In some embodiments, the prompt persists for the duration of the inspiratory hold.
