Referring to the embodiment shown in fig. 1 and fig. 2, the veterinary anesthesia apparatus of the present embodiment includes a gas source (not shown), an anesthesia output device 10, a gas source interface 20, a breathing interface 30, a breathing circuit 40, a breathing assistance device 50, a parameter acquiring device 60, a memory 70, a processor 80 and a display 90.

The gas source is used for providing gas. The gas may be oxygen, nitrous oxide (laughing gas), air, or the like. In some embodiments, the gas source is supplied by a compressed gas cylinder (or a central gas supply source)The kind of the supplied gas is oxygen O₂Laughing gas N₂O, air, etc. The gas source can also comprise a pressure gauge, a pressure regulator, a flowmeter, a pressure reducing valve and N₂O-O₂Conventional components such as the proportional control protection device are not described in detail herein. In other embodiments, the gas source may also be an external device separate from the veterinary anesthesia machine.

The anesthetic agent used in the anesthesia machine is usually in a liquid state, and in this embodiment, the anesthetic vaporizer is used as the anesthetic output device 10 to convert the stored anesthetic agent into anesthetic vapor, and the anesthetic vapor is mixed with the gas input by the gas source and then input into the breathing circuit 40 through the gas source interface 20. In some embodiments, the device can be combined with a microcomputer and a sensor to form an electric control evaporator, so that the automation of the concentration control of the anesthetic is realized, the possibility of manual misoperation is reduced, and the safety of inhalation anesthesia is improved.

The breathing circuit 40 comprises an inspiration passage 41a and an expiration passage 41b, wherein the inspiration passage 41a is provided with a gas inlet for introducing anesthetic gas, the gas source and the anesthetic output device 10 are respectively communicated with the gas inlet of the inspiration passage 41a, the inspiration passage 41a and the expiration passage 41b are respectively communicated with a breathing system of an animal, the inspiration passage 41a is responsible for conveying anesthetic mixed gas to the animal, and the expiration passage 41b is used for recovering gas expired by the animal and discharging redundant anesthetic gas into a residual gas collecting system. In this embodiment, the inhalation pathway 41a is connected between the respiratory interface 30 and the breathing assistance apparatus 50, and the respiratory interface 30 may be an endotracheal tube or a mask for wearing on the mouth and nose according to circumstances. The expiratory passageway 41b communicates with the respiratory interface 30 and closes into the inspiratory passageway 41a so that gas exhaled by the animal can be re-fed into the inspiratory passageway 41 a. The intake passage 41a is also provided with CO₂Absorber 43, CO₂The absorber 43 is located between the breathing assistance device 50 and the inhalation valve 42a and functions to filter CO in the gas entering the inhalation passage 41a from the exhalation passage 41b₂. In some embodiments, the exhalation passageways 41b may also be connected between the breathing interface 30 and the breathing assistance apparatus 50.

Valves for controlling the flow of gas are provided in the breathing circuit 40. in some embodiments, the valves may include an inhalation valve 42a and an exhalation valve 42b, the inhalation valve 42a being disposed in the inhalation path 41a and the exhalation valve 42b being disposed in the exhalation path 41 b. The inhalation valve 42a and the exhalation valve 42b are respectively one-way valves, the opening direction of the inhalation valve 42a faces to the animal, and the opening direction of the exhalation valve 42b is far away from the animal, so that the inhalation valve 42a is opened and the exhalation valve 42b is closed when the animal inhales; when the animal exhales, the exhalation valve 42b is opened and the inhalation valve 42a is closed. In some embodiments, the inhalation valve 42a and the exhalation valve 42b can also be general control valves, and the processor 80 controls the corresponding control valves to open or close, for example, during an inhalation phase, the processor 80 can control the inhalation valve 42a on the inhalation path 41a to open and close the exhalation valve 42b on the exhalation path 41b, so that the animal can inhale the gas smoothly; during the expiration phase, the processor 80 may control the expiration valve 42b on the expiration channel 41b to open and close the inspiration valve 42a on the inspiration channel 41a, so that the animal can smoothly exhale the gas.

The breathing assistance apparatus 50 is used to assist and control animal breathing and includes a mechanically controlled ventilation module 51a and a manual ventilation module 51b that can be switched between ventilation modes by a mechanically or manually controlled switch, such as a three-way regulating valve 52, so that the anesthesia machine can provide the animals with a mechanically controlled ventilation mode and a manual ventilation mode. In this embodiment, the manual ventilation module 51b includes an air bag, and when the manual ventilation mode is used for ventilation, the breathing circuit 40 is connected to the air bag through the switching three-way regulating valve 52, so that the medical staff such as an anesthesiologist or an operating doctor manually presses the air bag to control the breathing of the animal. When the mechanically controlled ventilation module 51a is used for ventilation, the mechanically controlled ventilation module 51a is connected into the breathing circuit 40 through the switching three-way regulating valve 52, and ventilation support is provided for the animal by using machine ventilation instead of manually pressing the air bag. A branch 41c is provided on a conduit of the air bag communicating with the inhalation passage 41a, and a breather valve 42c is provided on an exhaust port at the end of the branch 41c for ensuring a stable pressure in the breathing circuit 40 in the manual ventilation mode. In the manual ventilation mode, if the pressure in the breathing circuit 40 is too high and the pressure in the branch 41c is also too high, the breathing valve 42c is automatically opened, and a part of gas in the breathing circuit 40 is discharged through the breathing valve 42c, so that the pressure in the breathing circuit 40 is reduced, and the lung injury of an animal caused by the too high pressure in the breathing circuit 40 when the air bag is manually pressed is avoided.

When the manual air bag is connected into the breathing circuit 40 by switching the state of the three-way regulating valve 52, when the animal needs to be assisted to inhale, as shown in fig. 1, the air bag can be pressed by hands or other tools, the air in the air bag is pressed to enter the breathing circuit 40 through the three-way regulating valve 52, at the moment, the inhalation valve 42a is in an open state under the action of the airflow, the exhalation valve 42b is in a closed state under the action of the airflow, and therefore, the airflow passes through the CO₂The absorber 43 reaches the suction valve 42a and the carbon dioxide in the gas stream is in CO₂Filtered in the absorber, filtered CO₂The mixed gas is mixed with the anesthetic gas mixture outputted from the anesthetic output device 10, and then flows into the inhalation passage 41a through the inhalation valve 42a, and then enters the respiratory system of the animal through the respiratory interface 30, and the direction of the flow is shown by the arrow in fig. 1 in the inhalation phase. When it is desired to assist the animal in exhaling, the bladder is released and resiliently returns to its original configuration, as shown in figure 2, in which the pressure is reduced and the airflow in the breathing circuit 40 flows back into the bladder, in which case the inspiration valve 42a is closed and the expiration valve 42b is opened and the airflow in the animal's airway flows back into the bladder through the expiration valve 42b, the direction of the airflow during the expiration phase being shown by the arrows in figure 2.

The parameter acquiring means 60 is used for acquiring a measurement signal of at least one ventilation parameter and a measurement signal of a physiological parameter of the animal during ventilation. Ventilation parameters include, but are not limited to, airway pressure, airway flow rate, and lung volume, and physiological parameters include, but are not limited to, blood oxygen saturation, and the like. In some embodiments, the parameter acquiring device 60 may be a sensor placed in the animal or in the breathing circuit 40, and in other embodiments, the veterinary anesthesia machine may acquire the measurement signal of the ventilation parameter and the measurement signal of the physiological parameter through a third-party device, for example, a veterinary monitor.

The memory 70 is used to store data or programs, for example, the memory 70 may store initial image frames or temporarily not immediately displayed image frames generated by the processor 80, which may be 2D or 3D images, or the memory 70 may store a graphical user interface, one or more default image display settings, programming instructions for the processor 80. The memory 70 may be a tangible and non-transitory computer readable medium such as flash memory, RAM, ROM, EEPROM, and the like.

The processor 80 executes a program to process data stored in the memory 70 or data acquired by the parameter acquisition device 60. In this embodiment, the processor 80 generates a corresponding ventilation parameter waveform according to the acquired measurement signal of the ventilation parameter, and extracts a first parameter value 121 corresponding to each ventilation parameter waveform, where the first parameter value 121 is used to represent a main index of the corresponding ventilation parameter waveform. For example, the ventilation parameters include airway pressure (Paw), airway Flow rate (Flow), and lung Volume (Volume), and the processor 80 generates a corresponding airway pressure waveform 111, airway Flow rate waveform, and lung Volume waveform, wherein the processor 80 obtains two first parameter values 121 from the airway pressure waveform 111, namely PEAK airway Pressure (PEAK), which is indicative of the highest pressure value in the airway during ventilation, and Positive End Expiratory Pressure (PEEP), which is indicative of the pressure in the end expiratory airway. The processor 80 is further configured to generate a main interface 100 and output the main interface 100 to the display 90 for display, wherein the main interface 100 includes a waveform display area 110 and a parameter value display area 120, the waveform display area 110 is configured to display at least one ventilation parameter waveform of the ventilation parameter waveforms, and the parameter value display area 120 is configured to display a first parameter value 121 corresponding to the ventilation parameter waveform in the waveform display area 110. For example, in the embodiment shown in fig. 3, waveform display area 110 is positioned above parameter value display area 120, processor 80 displays airway pressure waveform 111 in waveform display area 110, and accordingly, processor 80 displays the peak airway pressure and the terminal positive airway pressure corresponding to airway pressure waveform 111 in parameter value display area 120. While in the embodiment shown in fig. 4, the ventilation parameters also include end-tidal carbon dioxide (EtCO)₂) Therefore, the ventilation parameter waveform further includes an end-tidal carbon dioxide waveform 112 (hereinafter referred to as carbon dioxide waveform 112), in fig. 4, the waveform display area 110 and the parameter value display area 120 are arranged in a left-right layout manner, and not only the airway pressure waveform 111 but also the carbon dioxide waveform 112 are displayed in the waveform display area 110, and the end-tidal carbon dioxide value is also displayed in the parameter value display area 120.

In other embodiments, the processor 80 further obtains at least one second parameter value 122 for characterizing a physiological condition of the animal based on the measurement signal of the at least one ventilation parameter and/or the measurement signal of the physiological parameter, for example, the second parameter value 122 is generated to include a tidal volume (Vt) representing a volume of gas inhaled and exhaled by the animal at each time, a minute lung volume (MV) representing a total amount of gas inhaled and exhaled by the animal per minute, and a respiratory frequency (RR) representing a number of breaths per minute by the animal. A second parameter value 122 is also displayed in the parameter value display area 120, such as in FIG. 3, which also displays the tidal volume, minute lung volume, and respiratory rate in the parameter value display area 120.

The main interface 100 includes a ventilation parameter waveform, a first parameter value 121 that can represent a main index of the ventilation parameter waveform, and a second parameter value 122 of an animal physiological condition, so as to satisfy information required by a user as much as possible in a case where a display area is small.

In some embodiments, the font sizes of the first parameter value 121 and the second parameter value 122 in the parameter value display area 120 may be the largest in the entire main interface 100, so that the user can acquire the key information more quickly and accurately. In the embodiments shown in fig. 3 and 4, the first parameter value 121 and the second parameter value 122 are displayed in a digital manner, and it can be seen that the font of the first parameter value 121 and the second parameter value 122 is the largest among the numbers of the main interface 100.

When the display 90 displays the main interface 100, the processor 80 detects whether a waveform configuration command is received, the waveform configuration command is used to convert the ventilation parameter waveform currently displayed into another ventilation parameter waveform, and if the waveform configuration command is received, the ventilation parameter waveform in the waveform display area 110 is reconfigured according to the waveform configuration command, that is, the ventilation parameter waveform displayed in the waveform display area 110 can be changed according to the waveform configuration command. In the embodiment shown in fig. 3, only one airway pressure waveform 111 is displayed in the waveform display area 110, and the airway pressure waveform 111 can be switched to an airway flow waveform or a lung volume waveform according to the waveform configuration command. In the embodiment shown in fig. 4, the waveform display area 110 displays two ventilation parameter waveforms, and the two ventilation parameter waveforms may be switched separately or only one ventilation parameter waveform may be switched according to the waveform configuration command.

The waveform configuration instruction may be generated or input in a variety of ways, and in some embodiments, the generating way of the waveform configuration instruction may be: the processor 80 generates a waveform name of each ventilation parameter waveform, then displays the waveform name of the ventilation parameter waveform in the waveform display area 110, then captures the clicking operation of the user on the area where the waveform name is located, and finally pops up a waveform name column based on the clicking operation of the user on the area where the waveform name is located. In the embodiment shown in fig. 3, the waveform name of the airway pressure waveform 111 is "Paw", when the screen of the display 90 is a non-touch screen, the user may move a cursor to the waveform name to perform a click operation through an external device such as a mouse, and when the screen of the display 90 is a touch screen, the user may also perform a click operation by touching the screen where the waveform name is located. The popped-up waveform name column in fig. 5 is a list, and includes waveform names of other ventilation parameter waveforms not displayed in the waveform display area 110, that is, the waveform name "Flow" of the airway Flow rate waveform and the waveform name "Volume" of the lung Volume waveform, after the waveform name column is popped up, the user's selection operation of the waveform name column is captured, the selected waveform name is determined according to the user's selection operation, a waveform configuration command is generated according to the selected waveform name, and then the selected ventilation parameter waveform is displayed in the waveform display area 110. For example, if the user selects "Flow," the airway pressure waveform 111 of the waveform display area 110 is replaced with an airway Flow waveform. In another embodiment, the waveform name field may be an input field for the user to input a character, the user inputs a waveform name in the input field, and if the input waveform name is one of the waveform names generated by the processor 80, the ventilation parameter waveform corresponding to the waveform name is displayed in the waveform display area 110.

The generation mode of the waveform configuration command takes the waveform name as an entry of the configuration waveform, and the operation is more friendly.

In other embodiments, a button or input field for configuring the waveform may be provided elsewhere on the main interface 100, and the user may click the button or input the name of the waveform of the ventilation parameter waveform to be displayed, thereby generating a waveform configuration command, determine the ventilation parameter waveform to be displayed in the waveform display area 110 based on the waveform configuration command, and then replace the ventilation parameter waveform originally in the waveform display area 110, partially or completely, with the ventilation parameter waveform to be displayed in the waveform display area 110 determined according to the waveform configuration command. For example, in the embodiment shown in fig. 4, another ventilation parameter waveform within waveform display area 110 may be changed while carbon dioxide waveform 112 is maintained within waveform display area 110.

After the ventilation parameter waveform in waveform display area 110 changes, processor 80 may automatically change first parameter value 121 in parameter value display area 120. For example, in the embodiment shown in fig. 3, after the airway pressure waveform 111 is replaced by the airway flow rate waveform, the airway peak pressure and the expiratory end positive pressure displayed below are changed to the first parameter value 121 corresponding to the airway flow rate waveform, so that the user can automatically obtain corresponding parameter information by switching the waveform.

In some embodiments, the first parameter value 121 and the second parameter value 122 displayed in the parameter value display area 120 may also be reconfigured. For example, in the embodiment shown in fig. 3, in addition to peak airway pressure and positive end-expiratory pressure, first parameter values 121 associated with airway pressure waveform 111 may include, but are not limited to, mean pressure and plateau pressure, and first parameter values 121 within parameter value display area 120 may be reconfigured in a manner similar to changing the ventilation parameter waveform such that at least one of mean pressure and plateau pressure is displayed within parameter value display area 120.

By the reconfiguration of the first parameter value 121 and the second parameter value 122, different second parameter values 122 and different first parameter values 121 related to the same ventilation parameter waveform can be displayed according to the needs of a user, thereby more efficiently utilizing the limited space of a screen.

In some embodiments, in addition to the primary interface 100, the processor 80 generates a secondary interface 200 within which secondary interface 200 is displayed auxiliary information generated by the processor 80 from the measured signal of the ventilation parameter and/or the measured signal of the physiological parameter, the secondary interface 200 being hidden when viewing is not required and being displayable on-screen with the primary interface 100 when viewing is required. In some embodiments, the processor 80 captures a click operation or a slide operation of the user in a predetermined area of the main interface 100, reduces the display area of the main interface 100 based on the click operation or the slide operation of the user in the predetermined area of the main interface 100, and displays the auxiliary interface 200 at least partially in an area left by the reduction of the main interface 100, so that the auxiliary interface 200 is displayed on the same screen as the main interface 100, for example, as shown in fig. 3, an area on the left side of the main interface 100 is the predetermined area, an icon is displayed and hidden in the area, and when the user clicks the icon, the auxiliary interface 200 pops up, and when the user clicks the icon, the auxiliary interface 200 is hidden. The auxiliary information in the auxiliary interface 200 includes at least two types, which will be described in detail below.

The first type of auxiliary information is used to assist in determining the physiological condition of the animal. For example, in the embodiment shown in fig. 6, the ventilation parameters include airway pressure and lung volume, and the auxiliary information includes a pressure-volume loop map generated from the airway pressure and lung volume, which is displayed in the auxiliary interface 200 to assist the user in determining lung compliance of the animal.

The second type of auxiliary information is used to represent a secondary indicator of the ventilation parameter waveform in the waveform display area 110, and the auxiliary information needs to be known to the user, but the current importance level is less than the first parameter value 121, so that the auxiliary information can be displayed on the auxiliary interface 200 for the user to selectively view. In the embodiment shown in fig. 6, the parameters below the pressure-volume loop map are used to characterize the secondary indicator of the ventilation parameter waveform.

In addition to the waveform display area 110 and the parameter value display area 120, the main interface 100 may be provided with other areas, such as a hot key area 130, a mode and parameter adjustment area 140, and a status bar area 150 in the embodiment shown in FIG. 3. Wherein the hot key zone 130 is located on the right side of the main interface 100. The mode and parameter adjustment area 140 is located below the parameter value display area 120, and the ventilation mode and corresponding parameter settings of the current veterinary anesthesia machine can be changed in response to the operating instructions for the mode and parameter adjustment area 140. The status bar area 150 is located above the waveform display area 110, and the status bar area 150 is used for displaying alarm information, time, electric quantity information, a timer, a general setting entrance of the anesthesia apparatus for animals, and the like. The layout of each region can be adjusted as required.

As shown in fig. 7, the present invention further provides a parameter display method for a veterinary anesthesia machine, which comprises the following steps:

step 10, obtaining a measurement signal of at least one ventilation parameter and a measurement signal of a physiological parameter of the animal during ventilation. Ventilation parameters include, but are not limited to, airway pressure, airway flow rate, and lung volume, and physiological parameters include, but are not limited to, blood oxygen saturation, and the like. The measurement signal of the ventilation parameter and the measurement signal of the physiological parameter can be obtained by the anesthesia apparatus for animals, or the measurement signal of the ventilation parameter and the measurement signal of the physiological parameter can be obtained by a third party device, for example, the measurement signal of the ventilation parameter and the measurement signal of the physiological parameter are obtained by a monitor for animals.

And 20, generating a corresponding ventilation parameter waveform according to the measurement signal of the ventilation parameter.

Step 30, extracting a first parameter value 121 corresponding to each ventilation parameter waveform. The first parameter value 121 is used to characterize a primary indicator of the corresponding ventilation parameter waveform.

For example, the ventilation parameters include airway pressure (Paw), airway Flow (Flow), and lung Volume (Volume), and the corresponding airway pressure waveform 111, airway Flow waveform, and lung Volume waveform are generated according to the three ventilation parameters, and two first parameter values 121, namely PEAK airway Pressure (PEAK) representing the highest pressure value in the airway during ventilation, and Positive End Expiratory Pressure (PEEP) representing the pressure in the end expiratory airway, are obtained from the airway pressure waveform 111.

In some embodiments, step 30 further comprises: at least one second parameter value 122 for characterizing a physiological condition of the animal is obtained from the measurement signal of the at least one ventilation parameter and/or the measurement signal of the physiological parameter.

For example, the generated second parameter values 122 include a tidal volume (Vt) representing the amount of gas that the animal breathes in and out at each time, a minute lung volume (MV) representing the total amount of gas that the animal breathes in and out per minute, and a breathing rate (RR) representing the number of breaths per minute.

And step 40, generating a main interface. The main interface includes a waveform display area 110 and a parameter value display area 120, the waveform display area 110 is used for displaying at least one ventilation parameter waveform in each ventilation parameter waveform, and the parameter value display area 120 is used for displaying a second parameter value 122 and a first parameter value 121 corresponding to the ventilation parameter waveform in the waveform display area 110.

At least one ventilation parameter waveform of the ventilation parameter waveforms is displayed in a waveform display area 110, step 50.

Step 60, the first parameter value 121 is displayed in the parameter value display area 120. Wherein the first parameter value 121 in the parameter value display area 120 corresponds to the ventilation parameter waveform in the waveform display area 110.

For example, in the embodiment shown in FIG. 3, waveform display area 110 is positioned above parameter value display area 120, airway pressure waveform 111 is displayed in waveform display area 110, and accordingly, peak airway pressure and end-expiratory pressure corresponding to airway pressure waveform 111 are displayed in parameter value display area 120, while in the embodiment shown in FIG. 4, the ventilation parameters also include end-expiratory carbon dioxide (EtCO)₂) Therefore, the ventilation parameter waveform further includes an end-tidal carbon dioxide waveform 112 (hereinafter referred to as carbon dioxide waveform 112), in fig. 4, the waveform display area 110 and the parameter value display area 120 are arranged in a left-right layout manner, and not only the airway pressure waveform 111 but also the carbon dioxide waveform 112 are displayed in the waveform display area 110, and the end-tidal carbon dioxide value is also displayed in the parameter value display area 120.

In some embodiments, after obtaining the second parameter 122, step 60 further comprises: the second parameter value 122 is displayed in the parameter value display area 120. For example, tidal volume, minute lung volume, and respiratory rate are also displayed in the parameter value display area 120 in fig. 3.

The font sizes of the first parameter value 121 and the second parameter value 122 in the parameter value display area 120 may be the largest in the entire main interface 100, so that the user can more quickly and accurately acquire the key information. In the embodiments shown in fig. 3 and 4, the first parameter value 121 and the second parameter value 122 are displayed in a digital manner, and it can be seen that the font of the first parameter value 121 and the second parameter value 122 is the largest among the numbers of the main interface 100.

And step 70, detecting whether a waveform configuration instruction is received, executing step 80 if the waveform configuration instruction is received, and continuing to execute step 70 if the waveform configuration instruction is not received. The waveform configuration instructions are for transforming a currently displayed ventilation parameter waveform to another ventilation parameter waveform. That is, the ventilation parameter waveform displayed within the waveform display area 110 may be changed according to the waveform configuration instructions.

The waveform configuration command may be generated or input in a variety of ways, and in some embodiments, the generating way of the waveform configuration command, as shown in fig. 8, may include the steps of:

step 71, generating the waveform name of each ventilation parameter waveform.

And step 72, displaying the waveform name of the ventilation parameter waveform in the waveform display area 110.

And step 73, capturing the clicking operation of the user on the area where the waveform name is located.

For example, in the embodiment shown in fig. 3, the waveform name of the airway pressure waveform 111 is "Paw", when the screen is a non-touch screen, the user may move a cursor to the waveform name by using an external device such as a mouse to perform a click operation, and when the screen is a touch screen, the user may also perform a click operation by touching the screen where the waveform name is located.

And step 74, popping up a waveform name column based on the clicking operation of the user on the area where the waveform name is located.

In the embodiment shown in fig. 5, the popped waveform name column is a list including the waveform names of other ventilation parameter waveforms not shown in the waveform display area 110, i.e., the waveform name "Flow" of the airway Flow waveform and the waveform name "Volume" of the lung Volume waveform.

Step 75, generate waveform configuration instructions based on the user input in the waveform name field.

In the embodiment shown in fig. 5, after the waveform name bar is popped up, the user's selection of the waveform name in the waveform name bar is captured, the selected waveform name is determined according to the user's selection, a waveform configuration command is generated according to the selected waveform name, and then the selected ventilation parameter waveform can be displayed in the waveform display area 110. For example, if the user selects "Flow," the airway pressure waveform 111 of the waveform display area 110 is replaced with an airway Flow waveform. In another embodiment, the waveform name field may be an input field for the user to input a character, the user inputs a waveform name in the input field, and if the input waveform name is one of the generated waveform names, the ventilation parameter waveform corresponding to the waveform name is displayed in the waveform display area 110.

In other embodiments, a button or input field for configuring the waveform may be provided elsewhere on the main interface 100, and the user clicks on the button or enters the name of the waveform of the ventilation parameter waveform to be displayed, thereby generating the waveform configuration instructions. The ventilation parameter waveform to be displayed in the waveform display area 110 is determined based on the waveform configuration instructions, and then the ventilation parameter waveform originally in the waveform display area 110 is partially or fully replaced with the ventilation parameter waveform to be displayed in the waveform display area 110 determined according to the waveform configuration instructions. For example, in the embodiment shown in fig. 4, another ventilation parameter waveform within waveform display area 110 may be changed while carbon dioxide waveform 112 is maintained within waveform display area 110.

The ventilation parameter waveforms in the waveform display area 110 are reconfigured 80 according to the waveform configuration instructions.

The manner of reconfiguring the ventilation parameter waveform has been described in step 70, and more specifically, in the embodiment shown in fig. 3, only one airway pressure waveform 111 is displayed in the waveform display area 110, and the airway pressure waveform 111 can be switched to an airway flow rate waveform or a lung volume waveform according to the waveform configuration command. In the embodiment shown in fig. 4, the waveform display area 110 displays two ventilation parameter waveforms, and the two ventilation parameter waveforms may be switched separately or only one ventilation parameter waveform may be switched according to the waveform configuration command.

The first parameter value 121 within the parameter value display area 120 is changed based on the transformation of the ventilation parameter waveform, step 90.

The first parameter value 121 in the parameter value display area 120 is automatically changed according to the change of the ventilation parameter waveform. For example, in the embodiment shown in fig. 3, after the airway pressure waveform 111 is replaced by the airway flow rate waveform, the airway peak pressure and the expiratory end positive pressure displayed below are changed to the first parameter value 121 corresponding to the airway flow rate waveform, so that the user can automatically obtain corresponding parameter information by switching the waveform.

In some embodiments, in addition to the primary interface 100, a secondary interface 200 is generated, within which secondary interface 200 is used to display secondary information generated from the measurement signal of the ventilation parameter and/or the measurement signal of the physiological parameter, the secondary interface 200 being hidden when viewing is not required and being displayable on-screen with the primary interface 100 when viewing is required. In some embodiments, the click operation or the slide operation of the user in the predetermined area of the main interface 100 is captured, the display area of the main interface 100 is reduced based on the click operation or the slide operation of the user in the predetermined area of the main interface 100, and the auxiliary interface 200 is at least partially displayed in the area left by the reduction of the main interface 100, so that the auxiliary interface 200 is displayed on the same screen as the main interface 100, for example, as shown in fig. 3, an area on the left side of the main interface 100 is the predetermined area, an icon is displayed and hidden in the area, when the user clicks the icon, the auxiliary interface 200 pops up, and when the user clicks the icon, the auxiliary interface 200 is hidden. The auxiliary information in the auxiliary interface 200 includes at least two types, which will be described in detail below.

The second type of auxiliary information is used to represent a secondary indicator of the ventilation parameter waveform in the waveform display area 110, and the auxiliary information needs to be known to the user, but the current importance level is less than the first parameter value 121, so that the auxiliary information can be displayed on the auxiliary interface 200 for the user to selectively view. In the embodiment shown in fig. 6, the parameters below the pressure-volume loop map are used to characterize a secondary indicator of the ventilation parameter waveform.

In addition to the waveform display area 110 and the parameter value display area 120, the main interface 100 may be provided with other areas, such as a hot key area 130, a mode and parameter adjustment area 140, and a status bar area 150 in the embodiment shown in FIG. 3. Wherein the hot key zone 130 is located on the right side of the main interface 100. The mode and parameter adjustment area 140 is located below the parameter value display area 120, and the ventilation mode and corresponding parameter setting of the current anesthesia machine can be changed in response to the operation command for the mode and parameter adjustment area 140. The status bar area 150 is located above the waveform display area 110, and the status bar area 150 is used for displaying alarm information, time, electric quantity information, a timer, a general setting entrance of the anesthesia apparatus for animals, and the like. The layout of each region can be adjusted as required.

The above embodiment displays the ventilation parameter waveform, and also displays the related first parameter value and the second parameter value in the main interface, and the ventilation parameter waveform can be switched, and the related first parameter value is switched after switching. In addition, a concealable auxiliary interface is provided, and auxiliary information for the user to refer to is displayed in the auxiliary interface, so that more required parameter information can be displayed in a limited screen, the key points in the parameter information can be highlighted, and the user can conveniently view the parameter information.

For a person skilled in the art to which the invention pertains, several simple deductions, modifications or substitutions may be made according to the idea of the invention.
