Description

Technical Field

[0001] This invention relates to the field of veterinary medical equipment, specifically to a veterinary anesthesia machine and a self-inspection guide method for leaks in a veterinary anesthesia machine. Background Technology

[0002] Like humans, animals require external anesthesia machines to provide respiratory support and anesthesia when undergoing surgery due to illness or other reasons. Veterinary anesthesia machines perform power-on self-tests and gas leak self-tests upon startup. The gas leak self-test checks for gas leaks within the breathing circuit. Some veterinary anesthesia machines have two gas circuits: one for machine-controlled ventilation and the other for manual ventilation. Both circuits can perform gas leak self-tests, but the steps required differ depending on the specific circuit. Providing users with more intuitive and comprehensive guidance during the leak self-test of veterinary anesthesia machines is an issue that needs improvement or resolution. Summary of the Invention

[0003] According to the first aspect, one embodiment provides a self-inspection guidance method for leaks in a veterinary anesthesia machine, comprising:

[0004] The system detects whether the veterinary anesthesia machine has entered a leak self-check state. If it has entered the leak self-check state, a guidance interface is displayed, which includes an information display area.

[0005] The information display area displays guidance information corresponding to the currently selected test ventilation mode. The test ventilation mode can be switched between machine-controlled ventilation mode and manual ventilation mode. The machine-controlled ventilation mode and manual ventilation mode each have corresponding guidance information. The guidance information is used to guide the operation steps of gas leak self-test in the corresponding ventilation mode.

[0006] Detect whether user input is received, such as mode switching commands, leak self-check commands, or guidance commands;

[0007] The test ventilation mode is switched based on the mode switching command, and the content displayed in the information display area is replaced with the guidance information corresponding to the test ventilation mode after the switch. The system then checks again whether the user input mode switching command, leak self-check command or guidance command has been received.

[0008] Based on the leak self-test command, the gas leak self-test is initiated, the leak self-test result is obtained, and the guidance information in the information display area is replaced with the self-test result information. The self-test result information is used to characterize the leak self-test result and / or to guide the operation steps after obtaining the leak self-test result in the test ventilation mode. The system then checks again whether the user input mode switching command has been received.

[0009] The guidance interface is replaced with a pre-set operation interface based on the guidance instructions.

[0010] According to a second aspect, one embodiment provides a veterinary anesthesia machine, comprising:

[0011] Gas source interface, used to connect to a gas source;

[0012] The breathing circuit connects the gas source interface to the animal's respiratory system to deliver gas supplied by the gas source to the animal and receive gas exhaled by the animal.

[0013] Anesthesia output device, used to mix stored anesthetic drugs with input gas and output them into the breathing circuit;

[0014] A respiratory assist device provides ventilation support to an animal through a breathing circuit, controlling the delivery of gas supplied by a gas source, gas exhaled by the animal, and gas mixed with anesthetic from an anesthesia output device to the animal. The respiratory assist device includes a machine-controlled ventilation module and a manual ventilation module. The veterinary anesthesia machine has a machine-controlled ventilation mode corresponding to the machine-controlled ventilation module and a manual ventilation mode corresponding to the manual ventilation module.

[0015] The memory is used to store the pre-set operation interface, the guidance information corresponding to the machine-controlled ventilation mode, and the guidance information corresponding to the manual ventilation mode. The guidance information is used to guide the operation steps of gas leak self-test in the corresponding ventilation mode.

[0016] Processor, used for:

[0017] The system detects whether the veterinary anesthesia machine has entered a leak self-check state. If it has entered the leak self-check state, the control display shows a guidance interface, which includes an information display area.

[0018] The display is controlled to show guidance information corresponding to the currently selected test ventilation mode in the information display area. The test ventilation mode can be switched between machine-controlled ventilation mode and manual ventilation mode.

[0019] Detect whether user input is received, such as mode switching commands, leak self-check commands, or guidance commands;

[0020] The test ventilation mode is switched based on the mode switching command, and the content displayed in the information display area is replaced with the guidance information corresponding to the test ventilation mode after the switch. The system then checks again whether the user input mode switching command, leak self-check command or guidance command has been received.

[0021] Based on the leak self-test command, the gas leak self-test is initiated, the leak self-test result is obtained, and the guidance information in the information display area is replaced with the self-test result information. The self-test result information is used to characterize the leak self-test result and / or to guide the operation steps after obtaining the leak self-test result in the test ventilation mode. The system then checks again whether the user input mode switching command has been received.

[0022] The guidance interface is replaced with the operation interface based on the guidance instructions;

[0023] A display, used to show a guidance interface or operation interface under the control of the processor.

[0024] According to a third aspect, one embodiment provides a computer-readable storage medium, characterized in that it includes a program that can be executed by a processor to implement the method of the first aspect.

[0025] In the above embodiments, after the veterinary anesthesia machine enters the leak self-check state, it will provide the user with guidance information for the selected test ventilation mode. The user can complete the corresponding operations according to the guidance information. Furthermore, the test ventilation mode can be switched between machine-controlled ventilation mode and manual ventilation mode, and the user can select the guidance information to view as needed, providing more comprehensive guidance. In addition, the veterinary anesthesia machine also provides users with a "quick entry" to frequently used operating interfaces, thus offering users more choices. Attached Figure Description

[0064] 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.

[0065] 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.

[0066] 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).

[0067] Please refer to Figure 1 and Figure 2 The present invention provides a veterinary anesthesia machine, including 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 assist device 50, a memory 60, a processor 70, and a display 80.

[0068] A gas source is used to supply gas. This gas can typically be oxygen, nitrous oxide (laughing gas), or air. In some embodiments, the gas source uses compressed gas cylinders (or a central gas supply), supplying oxygen (O2), nitrous oxide (N2O), or air. The gas source may also include conventional components such as pressure gauges, pressure regulators, flow meters, pressure reducing valves, and N2O-O2 proportional control and protection devices, which will not be detailed here. In other embodiments, the gas source can also be an external device independent of the veterinary anesthesia machine.

[0069] The anesthetics used in anesthesia machines are typically liquid. In this embodiment, the anesthetic vaporizer serves as the anesthetic output device 10, converting the stored anesthetic into anesthetic vapor, which is then mixed with the gas input from the gas source and fed into the breathing circuit 40 via the gas source interface 20. In some embodiments, it can be combined with a microcomputer and sensors to form an electronically controlled vaporizer, automating the control of anesthetic concentration, reducing the possibility of human error, and improving the safety of inhalation anesthesia.

[0070] The breathing circuit 40 includes an inhalation passage 41a and an expiratory passage 41b. The inhalation passage 41a has an inlet for introducing anesthetic gas. A gas source and an anesthesia output device 10 are respectively connected to the inlet of the inhalation passage 41a. The inhalation passage 41a and expiratory passage 41b are respectively connected to the animal's respiratory system. The inhalation passage 41a is responsible for delivering the anesthetic gas mixture to the animal, and the expiratory passage 41b is used to recover the gas exhaled by the animal and discharge excess anesthetic gas into a residual gas collection system. In this embodiment, the inhalation passage 41a is connected between the breathing interface 30 and the breathing assist device 50. Depending on the situation, the breathing interface 30 can be an endotracheal tube or a mask worn over the mouth and nose. The expiratory passage 41b is connected to the breathing interface 30 and closed into the inhalation passage 41a, thereby allowing the gas exhaled by the animal to be reintroduced into the inhalation passage 41a. A CO2 absorber 43 is also provided on the inhalation passage 41a. The CO2 absorber 43 is located between the breathing assist device 50 and the inhalation valve 42a, and its function is to filter CO2 in the gas entering the inhalation passage 41a from the exhalation passage 41b. In some embodiments, the exhalation passage 41b may also be connected between the breathing interface 30 and the breathing assist device 50.

[0071] A valve for controlling the gas flow direction is provided within the breathing circuit 40. In some embodiments, the valve may include an inhalation valve 42a and an exhalation valve 42b. The inhalation valve 42a is located on the inhalation passage 41a, and the exhalation valve 42b is located on the exhalation passage 41b. Both the inhalation valve 42a and the exhalation valve 42b are one-way valves. The opening direction of the inhalation valve 42a is towards the animal, and the opening direction of the exhalation valve 42b is away from the animal. Thus, when the animal inhales, the inhalation valve 42a is open and the exhalation valve 42b is closed; when the animal exhales, the exhalation valve 42b is open 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, which are controlled by the processor 70 to open or close. For example, during the inhalation phase, the processor 70 can control the inhalation valve 42a on the inhalation passage 41a to open and the exhalation valve 42b on the exhalation passage 41b to close, so that the animal can smoothly inhale gas; during the exhalation phase, the processor 70 can control the exhalation valve 42b on the exhalation passage 41b to open and the inhalation valve 42a on the inhalation passage 41a to close, so that the animal can smoothly exhale gas.

[0072] The respiratory support device 50 is used to assist and control animal respiration. It includes a machine-controlled ventilation module 51a and a manual ventilation module 51b. The ventilation mode can be switched via a machine-controlled or manual switch (e.g., a three-way regulating valve 52), allowing the anesthesia machine to provide both machine-controlled and manual ventilation modes to the animal. In this embodiment, the manual ventilation module 51b includes an air bag. When ventilation is performed in manual mode, the breathing circuit 40 is connected to the air bag via the three-way regulating valve 52, and medical personnel such as anesthesiologists or surgeons control the animal's breathing by manually pressing the air bag. When ventilation is performed using the machine-controlled ventilation module 51a, the machine-controlled ventilation module 51a is connected to the breathing circuit 40 via the three-way regulating valve 52, providing ventilation support to the animal by replacing manual pressure on the air bag with machine ventilation. A branch line 41c is provided on the tubing connecting the air sac and the inspiratory passage 41a. A breathing valve 42c is installed at the exhaust port at the end of this branch line 41c to ensure stable pressure within the breathing circuit 40 in manual ventilation mode. In manual ventilation mode, if the pressure within the breathing circuit 40 is too high, the pressure within the branch line 41c will also be too high. In this case, the breathing valve 42c will automatically open, allowing some gas to be expelled from the breathing circuit 40, thereby reducing the pressure within the breathing circuit 40 and preventing lung damage to the animal due to excessive pressure in the breathing circuit 40 when the air sac is manually pressed.

[0073] When the state of the three-way regulating valve 52 is switched to connect the manual air bag to the breathing circuit 40, when it is necessary to assist the animal's breathing, such as... Figure 1As shown, the air bladder can be squeezed by hand or other tools, and the gas in the air bladder is squeezed and enters the breathing circuit 40 through the three-way regulating valve 52. At this time, the inspiratory valve 42a is in the open state under the action of airflow, and the expiratory valve 42b is in the closed state under the action of airflow. Therefore, the airflow reaches the inspiratory valve 42a through the CO2 absorber 43. The carbon dioxide in the airflow is filtered in the CO2 absorber. The gas with filtered CO2 is mixed with the anesthetic mixed gas output by the anesthesia output device 10 and flows into the inspiratory passage 41a through the inspiratory valve 42a, and then enters the animal's respiratory system through the breathing interface 30. Figure 1 The arrows in the diagram indicate the direction of airflow during the inhalation phase. When assisted exhalation is needed, such as... Figure 2 As shown, when the air sac is released, it returns to its original shape due to elasticity, resulting in a decrease in pressure. Airflow in the breathing circuit 40 flows back into the air sac. In this situation, the inspiratory valve 42a closes, and the expiratory valve 42b opens, allowing airflow from the animal's respiratory tract to flow back into the air sac via the expiratory valve 42b. Figure 2 The arrows in the diagram indicate the direction of airflow during the exhalation phase.

[0074] As described above, the gas circuits for ventilating animals are not entirely the same depending on the ventilation mode (machine-controlled mode and manual mode). Furthermore, the procedures required for leak self-checks also differ between ventilation modes. This embodiment provides effective guidance for users on the necessary procedures under both ventilation modes to ensure successful leak self-checks.

[0075] The processor 70 is used to detect whether the veterinary anesthesia machine has entered a leak self-test state. The self-test of the veterinary anesthesia machine includes a power-on self-test and a leak self-test. In this embodiment, after a successful power-on self-test, the system automatically enters the leak self-test state.

[0076] If the system enters a leak self-test state, the processor 70 controls the display 80 to show a guidance interface. The guidance interface can be generated by the processor 70 after the veterinary anesthesia machine is turned on, or it can be pre-stored in the memory and then called by the processor 70 after the machine is turned on and output to the display 80 for display.

[0077] After entering the leak self-test state, the displayed guidance interface includes an information display area 1. The processor 70 controls the display 80 to display guidance information corresponding to the currently selected test ventilation mode within information display area 1. The test ventilation mode can be switched between machine-controlled ventilation mode and manual ventilation mode. Each mode has corresponding guidance information, which guides the operation steps for gas leak self-testing under the corresponding ventilation mode. Figure 3As shown, the initial test ventilation mode selected after power-on defaults to the machine-controlled ventilation mode. Information display area 1 displays guidance information corresponding to the machine-controlled ventilation mode. This guidance information includes at least two parts: the left side of information display area 1 provides textual instructions on the user's required operations for leak self-testing in machine-controlled ventilation mode; the right side of information display area 1 illustrates the required operations. Additionally, guidance information can be displayed in animation or video format. In other embodiments, the initial test ventilation mode may default to manual ventilation mode, or no default setting may be implemented, allowing the user to set the initial test ventilation mode after power-on. In this embodiment, after selecting the test ventilation mode, the user changes the ventilation module through operation.

[0078] When displaying the guidance interface, the processor 70 also detects whether it has received a mode switching command, a leak self-check command, or a guidance command input by the user. The mode switching command is used to switch the selected test ventilation mode and replace the content displayed in information display area 1 with the guidance information corresponding to the switched test ventilation mode. The leak self-check command is used to initiate the gas leak self-check of the veterinary anesthesia machine, and the guidance command is used to display a pre-set commonly used operation interface 500, which will be explained in detail below.

[0079] like Figure 3 In the illustrated embodiment, the guidance interface includes a first selection area 2a and a second selection area 2b. The first selection area 2a displays a first marker representing a machine-controlled ventilation mode, and the second selection area 2b displays a second marker representing a manual ventilation mode. For example, the first and second markers are textual representations of the ventilation modes as understood by the user. Based on the selected test ventilation mode, the corresponding selection area is set as an active area where user operation is acceptable, and the other selection area is set as an inactive area where user operation is not acceptable. Simultaneously, click or swipe operations within the active area are captured. If a click or swipe operation is captured within the active area, a mode switching command is generated. As shown in Figure 3, the selected test ventilation mode in the guidance interface is the machine-controlled ventilation mode; therefore, the first selection area 2a is an inactive area, and the second selection area 2b is an active area. If the user clicks the second selection area 2b (or swipes in other embodiments), a mode switching command is generated. Processor 70 switches the test ventilation mode based on the mode switching instruction, that is, it reselects the test ventilation mode, and then replaces the currently displayed guidance information in information display area 1 with the guidance information corresponding to the switched test ventilation mode. In other words, the guidance interface will change to... Figure 5 As shown, the guidance information in information display area 1 has been replaced with the guidance information corresponding to manual ventilation mode. It can be seen that both the text and the illustrations have changed. Then, it checks again whether it has received user input commands for mode switching, leak self-checking, or guidance. It's easy to understand that the guidance interface has changed to... Figure 5 As shown, the second selection area 2b becomes the inactive area, and the first selection area 2a becomes the active area.

[0080] In addition to the first selection area 2a and the second selection area 2b, the test ventilation mode can also be selected by setting menus, lists or button icons on the guidance interface, thus providing users with flexible self-test sequence selection.

[0081] like Figure 3 In the illustrated embodiment, the guidance information also includes a start button identifier 3 for generating a leak self-test command and a guide button identifier 4 for generating a guide command.

[0082] The guide button icon 4 is located in the lower right corner of the information display area 1. The word "standby" is displayed in the area where the guide button icon 4 is located, thus visually indicating its position to the user. Guidance instructions are generated based on the user's click on the guide button icon 4; that is, when the user clicks the guide button icon 4, the guidance interface is replaced with... Figure 9 The shown is a standby interface (an example of an operation interface 500). In other embodiments, the switched interface can also be other commonly used operation interfaces 500, and correspondingly, the characters on the guide button label 4 can also be changed accordingly.

[0083] The start button (marked 3) is also located in the lower right corner of the information display area 1. The word "continue" is displayed in the area where the start button (marked 3) is located, visually indicating its position to the user. Clicking the start button (marked 3) generates a leak self-check command, initiating a gas leak self-check. As the name suggests, after clicking the start button (marked 3), the veterinary anesthesia machine automatically detects whether there is a gas leak in the breathing circuit 40. Detection methods may include, but are not limited to, using pressure sensors, flow sensors, etc., installed within the breathing circuit 40 to acquire pressure and / or flow changes during ventilation to determine if a gas leak exists. After obtaining the leak self-check result, the veterinary anesthesia machine replaces the guidance information in the information display area 1 with the self-check result information. This self-check result information characterizes the leak self-check result and / or guides the operational steps after obtaining the leak self-check result in the test ventilation mode. The leak self-check result includes either normal or abnormal.

[0084] When the leak self-test result is normal, in some embodiments, such as Figure 4As shown, the self-test result information includes text indicating that the leak self-test result is normal. When the leak self-test result is abnormal, in addition to the text indicating that the leak self-test result is abnormal, the self-test result information also uses different colors to indicate the severity of the gas leak, and guides the user to check the parts where there may be gas leaks through text or graphics.

[0085] In some embodiments, the self-test result information also includes corresponding operation button icons displayed in the information display area 1 based on the leakage self-test result. Furthermore, it receives operation instructions obtained from manipulating the operation button icons, and based on the operation instructions, replaces the content displayed in the information display area 1 with content associated with the operation instructions, or replaces the guidance interface with an interface associated with the operation instructions. Specifically:

[0086] If the leak self-test result is normal, the operation button labels include mode switch button label 5 and / or guide button label 4.

[0087] like Figure 4 In the guidance interface shown, the mode switching button 5 is located in the lower right corner of the information display area 1. The character "continue" is displayed in the area where the mode switching button 5 is located, thus visually indicating the location of the mode switching button 5 to the user. The start button 3 is in the same position as the mode switching button 5 on the guidance interface, but the response obtained by clicking the character "continue" is different. A mode switching command is generated based on the user's click operation on the mode switching button 5. In other words, the user clicks... Figure 4 After the "continue" character in the lower right corner, the guidance interface on the display 80 changes. Figure 4 Replaced with Figure 5 The guide button label 4 can be reused. Figure 3 The guide button label 4 in the diagram, with its identical button label position, facilitates smooth operation for the user. In other embodiments, the mode switching button label 5 and the start button label 3 may be in different positions and may be labeled with different characters or symbols. Besides the mode switching button label 5, Figure 4 The guidance interface also displays a first selection area 2a and a second selection area 2b. Clicking the second selection area 2b will generate a mode switching command.

[0088] As described above, after obtaining a leak self-test result for one ventilation mode, if the result is normal, the user can either proceed to the leak self-test for another ventilation mode or skip the leak self-test for another ventilation mode and directly access the commonly used operating interface 500, providing the user with more options. Furthermore, if the user switches to another test ventilation mode based on a mode switching command, that is, by... Figure 4 The guidance interface shown has changed to the following: Figure 5 The guidance interface shown also displays... Figure 3 The first selection area 2a and the second selection area 2b of the guide interface shown, as well as the start button label 3 and the guide button label 4, have the following functions: Figure 3 The corresponding functions are the same in the shown guide interface. If the first selection area 2a is clicked, the monitor 80 will then display... Figure 3 The shown guide interface, if the guide button marked 4 is clicked, will display on monitor 80 again. Figure 9 The standby interface is shown. If the start button (marked 3) is clicked, the veterinary anesthesia machine will begin performing a gas leak self-check in manual ventilation mode. Similar to the machine-controlled ventilation mode, after obtaining the leak self-check results, the veterinary anesthesia machine will... Figure 5 As shown, the guidance information in information display area 1 is replaced with self-test result information, which is the self-test result information corresponding to manual ventilation mode. Figure 5 The shown guide interface also includes a first selection area 2a and a second selection area 2b, that is, in Figure 5 In the shown guide interface, you can switch to the first selection area 2a by clicking on it. Figure 3 The guidance interface is shown. As described above, in some embodiments, the guidance interface displays a first selection area 2a and a second selection area 2b so that the user can review the relevant operation steps at any time. Similar to the machine-controlled ventilation mode, if the leak self-test result is normal, the self-test result information of the manual ventilation mode may also include the above-mentioned mode switching button identifier 5 and guide button identifier 4. In some embodiments, if the leak self-test results of both the machine-controlled ventilation mode and the manual ventilation mode are normal, then the corresponding self-test result information may only include the guide button identifier 4, for example, as shown. Figure 6 The guidance interface shown is the one after obtaining the leak self-test result in manual ventilation mode. Prior to this, the leak self-test result in machine-controlled ventilation mode was normal. Figure 6 The guidance interface only shows the guide button (marked 4). Since both ventilation modes have shown normal results, the mode switching button (marked 5) is no longer provided.

[0089] When the leak self-test result is abnormal, the operation button labels include retest button label 6 and guide button label 4.

[0090] like Figure 8In the guidance interface shown, the retest button 6 is located in the lower right corner of the information display area 1. The word "retry" is displayed in the area where the retest button 6 is located, thus visually indicating the location of the retest button 6 to the user. Clicking the area containing the word "retry" generates a retest command. Based on the retest command, the processor 70 replaces the self-test result information in the information display area 1 with the guidance information for the currently selected test ventilation mode. Figure 8 After clicking the retest command in the shown guidance interface, the monitor 80 will display... Figure 5 The interface shown allows users to adjust and check the sealing of the breathing circuit, and perform a gas leak self-check again. Besides the mode switch button labeled 5, Figure 8 The guidance interface also displays a first selection area 2a and a second selection area 2b. Clicking the second selection area 2a will generate a mode switching command.

[0091] As described above, after obtaining a leak self-test result for a ventilation mode, if the leak self-test result is abnormal, the user can perform a gas leak self-test again in the current test ventilation mode, or enter a leak self-test for another ventilation mode, or directly enter the commonly used operation interface 500. In some embodiments, if the leak self-test result is abnormal, and the user selects to display the operation interface 500, then as follows... Figure 9 As shown, an error alert will be displayed on the operation interface 500. In some other embodiments, if the leak self-test result of the current ventilation mode is abnormal, and the leak self-test result of another ventilation mode has not yet been obtained, then the guide button 4 will not be provided in the current guidance interface; instead, the mode switching button 5 will be provided. That is, in the case of... Figure 7 The guide interface shown does not display the guide button icon 4.

[0092] In some embodiments, abnormal leakage self-test results include general abnormalities and severe abnormalities. If the leakage self-test result is a severe abnormality, then the guide button identifier 4 is hidden or the guide button identifier 4 is set to an inactive state where clickable operations are not allowed. That is, when the leakage self-test result is a severe abnormality, access to the commonly used operation interface 500 is not allowed.

[0093] In some embodiments, if a leak self-test result corresponding to a ventilation mode has been obtained, when switching the test ventilation mode, the leak result marker 7 is displayed in the guidance interface. The leak result marker 7 is used to characterize the leak self-test result obtained in the test ventilation mode before the switch. For example, Figure 5 For the reason Figure 4 This is a schematic diagram of the guidance interface after switching the test ventilation mode. In the first selection area 2a, a checkmark indicates the test ventilation mode before switching (i.e.,...). Figure 4The guide interface (corresponding to the test ventilation mode) displays the normal leak self-test results. Two examples are given below to illustrate the entire leak self-test process. For ease of explanation, the guide interface displaying the guidance information corresponding to the controlled ventilation mode is referred to as the first guide interface 100, the guide interface displaying the guidance information corresponding to the manual ventilation mode is referred to as the second guide interface 200, the guide interface displaying the self-test result information corresponding to the controlled ventilation mode is referred to as the third guide interface 300, and the guide interface displaying the self-test result information corresponding to the manual ventilation mode is referred to as the fourth guide interface 400. Figure 3 The first guidance interface is 100. Figure 5 For the second guidance interface 200, Figure 4 and Figure 7 The third guidance interface is 300. Figure 6 and Figure 8 This is the fourth guidance interface, 400.

[0094] In the first embodiment, the leak self-test results were normal in both ventilation modes, and the entire process was as follows: Figure 10 As shown. After entering the leak self-test state, the first guidance interface 100 is displayed first. You can enter the second guidance interface 200 by clicking the second selection area 2b, or enter the third guidance interface 300 by clicking the start button 3, or enter the operation interface 500 by clicking the guide button 4.

[0095] If the user clicks the "continue" character in the first guidance interface 100, they will enter the third guidance interface 300. In the third guidance interface 300, they can click the second selection area 2b or continue to click the "continue" character to enter the second guidance interface 200, or click the guide button icon 4 to enter the operation interface 500.

[0096] If the user clicks the "continue" character in the third guidance interface 300, they will enter the second guidance interface 200. In the second guidance interface 200, they can click the first selection area 2a to enter the first guidance interface 100, or continue to click the "continue" character to enter the fourth guidance interface 400, or click the guide button icon 4 to enter the operation interface 500.

[0097] If the user clicks the "continue" character in the second guidance interface 200, they will enter the fourth guidance interface 400. In the fourth guidance interface 400, they can click the first selection area 2a to enter the first guidance interface 100, or click the guide button icon 4 to enter the operation interface 500.

[0098] In the second embodiment, the leak self-test results in both ventilation modes were generally abnormal. The entire process is as follows: Figure 11As shown. After entering the leak self-test state, the first guidance interface 100 is displayed first. You can enter the second guidance interface 200 by clicking the second selection area 2b, or enter the third guidance interface 300 by clicking the start button 3, or enter the operation interface 500 by clicking the guide button 4.

[0099] If the user clicks the "continue" character in the first guidance interface 100, they will enter the third guidance interface 300. In the third guidance interface 300, they can click the second selection area 2b or continue to click the "continue" character to enter the second guidance interface 200, or click the "retry" character to return to the first guidance interface 100.

[0100] If the user clicks the "continue" character in the third guidance interface 300, they will enter the second guidance interface 200. In the second guidance interface 200, they can click the first selection area 2a to enter the first guidance interface 100, or continue to click the "continue" character to enter the fourth guidance interface 400, or click the guide button icon 4 to enter the operation interface 500.

[0101] If the user clicks the "continue" character in the second guidance interface 200, they will enter the fourth guidance interface 400. In the fourth guidance interface 400, they can click the first selection area 2a to enter the first guidance interface 100, or click the guide button 4 to enter the operation interface 500, or click the "retry" character to return to the second guidance interface 200.

[0102] As described above, if you keep clicking the "continue" button, you can complete a full leak self-test for both ventilation modes, thus providing users with a convenient and user-friendly interactive method to easily complete the necessary operations for gas leak self-testing.

[0103] Please refer to Figure 13 The present invention also provides a self-inspection guide method for leaks in veterinary anesthesia machines, including the following steps:

[0104] Step 1000: Check if the veterinary anesthesia machine has entered the leakage self-check state. If it has entered the leakage self-check state, proceed to step 2000; otherwise, continue to step 1000.

[0105] Step 2000: Display the guidance interface. The guidance interface includes information display area 1.

[0106] The guidance interface can be generated after the veterinary anesthesia machine is turned on, or it can be pre-stored in the memory.

[0107] Step 3000: Display guidance information corresponding to the currently selected test ventilation mode in information display area 1.

[0108] The ventilation mode can be switched between machine-controlled ventilation mode and manual ventilation mode. Each mode has corresponding guidance information, which guides the operation steps for gas leak self-testing in the corresponding ventilation mode. For example... Figure 3 As shown, the initial test ventilation mode selected after power-on defaults to the machine-controlled ventilation mode. Information display area 1 displays guidance information corresponding to the machine-controlled ventilation mode. This guidance information includes at least two parts: the left side of information display area 1 provides textual instructions on the user's required operations for leak self-testing in machine-controlled ventilation mode; the right side of information display area 1 illustrates the required operations. Additionally, guidance information can be displayed in the form of animation or video. In other embodiments, the initial test ventilation mode may also default to manual ventilation mode, or no default setting may be made, allowing the user to set the initial test ventilation mode after power-on.

[0109] Step 4100: Detect whether a mode switching instruction input by the user has been received. If a mode switching instruction has been received, proceed to step 5100; otherwise, proceed to step 4200.

[0110] The mode switching command is used to switch the selected test ventilation mode and replace the content displayed in information display area 1 with the guidance information corresponding to the switched test ventilation mode.

[0111] Step 4200: Check if a user-inputted guidance command has been received. If a guidance command has been received, proceed to step 5200; otherwise, proceed to step 4300. The guidance command is used to display a pre-set commonly used user interface 500.

[0112] Step 4300: Check if a leak self-check command input by the user has been received. If a leak self-check command is received, proceed to step 5300; otherwise, proceed to step 4100. The leak self-check command is used to initiate a gas leak self-check on the veterinary anesthesia machine.

[0113] Step 5100: Based on the mode switching command, switch the test ventilation mode and replace the content displayed in the information display area 1 with the guidance information corresponding to the switched test ventilation mode.

[0114] One method for generating mode switching instructions can be found by referring to Figure 3 ,like Figure 3In the illustrated embodiment, the guidance interface includes a first selection area 2a and a second selection area 2b. The first selection area 2a displays a first marker representing a machine-controlled ventilation mode, and the second selection area 2b displays a second marker representing a manual ventilation mode. For example, the first and second markers are textual representations of the ventilation modes as understood by the user. Based on the selected test ventilation mode, the corresponding selection area is set as an active area where user operation is acceptable, and the other selection area is set as an inactive area where user operation is not acceptable. Simultaneously, click or swipe operations within the active area are captured. If a click or swipe operation is captured within the active area, a mode switching command is generated. As shown in Figure 3, the selected test ventilation mode in the guidance interface is the machine-controlled ventilation mode; therefore, the first selection area 2a is an inactive area, and the second selection area 2b is an active area. If the user clicks the second selection area 2b (or swipes in other embodiments), a mode switching command is generated. The test ventilation mode is switched based on the mode switching command, that is, the test ventilation mode is reselected, and then the guidance information currently displayed in information display area 1 is replaced with the guidance information corresponding to the new test ventilation mode. In other words, the guidance interface will change to... Figure 5 As shown, the guidance information in information display area 1 is replaced with the guidance information corresponding to manual ventilation mode. It can be seen that both the text and the illustrations have changed. Then, step 4000 is executed again. It is easy to understand that the guidance interface changes to... Figure 5 As shown, the second selection area 2b becomes the inactive area, and the first selection area 2a becomes the active area.

[0115] In addition to the first selection area 2a and the second selection area 2b, the test ventilation mode can also be selected by setting menus, lists or button icons on the guidance interface, thus providing users with flexible self-test sequence selection.

[0116] Step 5200: Replace the guidance interface with a pre-set operation interface based on the guidance instructions.

[0117] One method for generating boot instructions can be found by referring to Figure 3 ,like Figure 3 In the illustrated embodiment, the guidance information includes a guidance button identifier 4 for generating guidance instructions. The guidance button identifier 4 is located in the lower right corner of the information display area 1, and the characters "standby" are displayed in the area where the guidance button identifier 4 is located, thus visually indicating the location of the guidance button identifier 4 to the user. Guidance instructions are generated based on the user's click operation on the guidance button identifier 4; that is, when the user clicks the guidance button identifier 4, the guidance interface is replaced with... Figure 9The shown is a standby interface (an example of an operation interface 500). In other embodiments, the switched interface can also be other commonly used operation interfaces 500, and correspondingly, the characters on the guide button label 4 can also be changed accordingly.

[0118] Step 5300: Initiate a gas leak self-test based on the leak self-test command, obtain the leak self-test result, replace the guidance information in information display area 1 with the self-test result information, and then execute step 4100'. The self-test result information is used to characterize the leak self-test result and / or guide the operation steps after obtaining the leak self-test result in the test ventilation mode. The leak self-test result includes normal or abnormal.

[0119] One method for generating a leak self-test command can be found by referring to Figure 3 ,like Figure 3 In the illustrated embodiment, the guidance information includes a start button icon 3 for generating a leak self-check command. The start button icon 3 is also located in the lower right corner of the information display area 1. The character "continue" is displayed in the area where the start button icon 3 is located, thus visually indicating the location of the start button icon 3 to the user. After the user clicks the start button icon 3, a leak self-check command is generated, and a gas leak self-check is initiated based on the leak self-check command. As the name suggests, after clicking the start button icon 3, the veterinary anesthesia machine automatically detects whether there is a gas leak in the breathing circuit 40. The detection method may include, but is not limited to, using pressure sensors, flow sensors, etc., installed in the breathing circuit 40 to obtain pressure changes and / or flow changes during ventilation to determine whether a gas leak exists. After obtaining the leak self-check result, the veterinary anesthesia machine replaces the guidance information in the information display area 1 with the self-check result information.

[0120] Step 4100a: Detect whether a mode switching instruction input by the user has been received. If a mode switching instruction has been received, proceed to step 5100; otherwise, continue to proceed to step 4100a.

[0121] The mode switching instruction in step 4100a can be generated as follows: Figure 4 In the guidance interface shown, information display area 1 displays the self-test result information corresponding to the organic controlled ventilation mode, and... Figure 4 The guidance interface also displays a first selection area 2a and a second selection area 2b. Clicking the second selection area 2b will generate a mode switching command.

[0122] In some embodiments, the self-test result information also includes corresponding operation button icons displayed in the information display area 1 based on the leakage self-test result. Furthermore, it receives operation instructions obtained from manipulating the operation button icons, and based on the operation instructions, replaces the content displayed in the information display area 1 with content associated with the operation instructions, or replaces the guidance interface with an interface associated with the operation instructions. Specifically:

[0123] If the leak self-test result is normal, the operation button labels include mode switch button label 5 and / or guide button label 4.

[0124] like Figure 4 In the guidance interface shown, the mode switching button 5 is located in the lower right corner of the information display area 1. The character "continue" is displayed in the area where the mode switching button 5 is located, thus visually indicating the location of the mode switching button 5 to the user. The start button 3 is in the same position as the mode switching button 5 on the guidance interface, but the response obtained by clicking the character "continue" is different. A mode switching command is generated based on the user's click operation on the mode switching button 5. In other words, the user clicks... Figure 4 After the "continue" character in the lower right corner, the guidance interface will change. Figure 4 Replaced with Figure 5 The guide button label 4 can be reused. Figure 3 The guide button label 4 is positioned identically to facilitate smooth operation for the user. In other embodiments, the mode switching button label 5 and the start button label 3 may be in different positions and may be labeled with different characters or symbols.

[0125] As described above, after obtaining a leak self-test result for one ventilation mode, if the result is normal, the user can either proceed to the leak self-test for another ventilation mode or skip the leak self-test for another ventilation mode and directly access the commonly used operating interface 500, providing the user with more options. Furthermore, if the user switches to another test ventilation mode based on a mode switching command, that is, by... Figure 4 The guidance interface shown has changed to the following: Figure 5 The guidance interface shown also displays... Figure 3 The first selection area 2a and the second selection area 2b of the guide interface shown, as well as the start button label 3 and the guide button label 4, have the following functions: Figure 3 The corresponding functions are the same in the shown guide interface. If you click the first selection area 2a, it will display again. Figure 3 The shown guide interface, if you click the guide button marked 4, will then display... Figure 9The standby interface is shown. If the start button (marked 3) is clicked, the veterinary anesthesia machine will begin performing a gas leak self-check in manual ventilation mode. Similar to the machine-controlled ventilation mode, after obtaining the leak self-check results, the veterinary anesthesia machine will... Figure 5 As shown, the guidance information in information display area 1 is replaced with self-test result information, which is the self-test result information corresponding to manual ventilation mode. Figure 5 The shown guide interface also includes a first selection area 2a and a second selection area 2b, that is, in Figure 5 In the shown guide interface, you can switch to the first selection area 2a by clicking on it. Figure 3 The guidance interface is shown. As described above, in some embodiments, the guidance interface displays a first selection area 2a and a second selection area 2b so that the user can review the relevant operation steps at any time. Similar to the machine-controlled ventilation mode, if the leak self-test result is normal, the self-test result information of the manual ventilation mode may also include the above-mentioned mode switching button identifier 5 and guide button identifier 4. In some embodiments, if the leak self-test results of both the machine-controlled ventilation mode and the manual ventilation mode are normal, then the corresponding self-test result information may only include the guide button identifier 4, for example, as shown. Figure 6 The guidance interface shown is the one after obtaining the leak self-test result in manual ventilation mode. Prior to this, the leak self-test result in machine-controlled ventilation mode was normal. Figure 6 The guidance interface only shows the guide button (marked 4). Since both ventilation modes have shown normal results, the mode switching button (marked 5) is no longer provided.

[0126] When the leak self-test result is abnormal, the operation button labels include retest button label 6 and guide button label 4.

[0127] like Figure 8 In the guidance interface shown, the retest button 6 is located in the lower right corner of information display area 1. The word "retry" is displayed in the area where the retest button 6 is located, visually indicating the position of the retest button 6 to the user. Clicking the area containing the word "retry" generates a retest command. Based on the retest command, the self-test result information in information display area 1 is replaced with guidance information for the currently selected test ventilation mode. Figure 8 After clicking the retest command in the shown guidance interface, it will display... Figure 5 The interface shown allows users to adjust and check the sealing of the breathing circuit, and perform a gas leak self-check again. Besides the mode switch button labeled 5, Figure 8 The guidance interface also displays a first selection area 2a and a second selection area 2b. Clicking the second selection area 2b will generate a mode switching command.

[0128] As described above, after obtaining a leak self-test result for a ventilation mode, if the leak self-test result is abnormal, the user can perform a gas leak self-test again in the current test ventilation mode, or enter a leak self-test for another ventilation mode, or directly enter the commonly used operation interface 500. In some embodiments, if the leak self-test result is abnormal, and the user selects to display the operation interface 500, then as follows... Figure 9 As shown, an error alert will be displayed on the operation interface 500. In some other embodiments, if the leak self-test result of the current ventilation mode is abnormal, and the leak self-test result of another ventilation mode has not yet been obtained, then the guide button 4 will not be provided in the current guidance interface; instead, the mode switching button 5 will be provided. That is, in the case of... Figure 7 The guide interface shown does not display the guide button icon 4.

[0129] In some embodiments, abnormal leakage self-test results include general abnormalities and severe abnormalities. If the leakage self-test result is a severe abnormality, then the guide button identifier 4 is hidden or the guide button identifier 4 is set to an inactive state where clickable operations are not allowed. That is, when the leakage self-test result is a severe abnormality, access to the commonly used operation interface 500 is not allowed.

[0130] In some embodiments, if a leak self-test result corresponding to a ventilation mode has been obtained, when switching the test ventilation mode, the leak result marker 7 is displayed in the guidance interface. The leak result marker 7 is used to characterize the leak self-test result obtained in the test ventilation mode before the switch. For example, Figure 5 For the reason Figure 4 This is a schematic diagram of the guidance interface after switching the test ventilation mode. In the first selection area 2a, a checkmark indicates the test ventilation mode before switching (i.e.,...). Figure 4 The guide interface (corresponding to the test ventilation mode) displays the normal leak self-test results. Two examples are given below to illustrate the entire leak self-test process. For ease of explanation, the guide interface displaying the guidance information corresponding to the controlled ventilation mode is referred to as the first guide interface 100, the guide interface displaying the guidance information corresponding to the manual ventilation mode is referred to as the second guide interface 200, the guide interface displaying the self-test result information corresponding to the controlled ventilation mode is referred to as the third guide interface 300, and the guide interface displaying the self-test result information corresponding to the manual ventilation mode is referred to as the fourth guide interface 400. Figure 3 The first guidance interface is 100. Figure 5 For the second guidance interface 200, Figure 4 and Figure 7 The third guidance interface is 300. Figure 6 and Figure 8 This is the fourth guidance interface, 400.

[0131] In the first embodiment, the leak self-test results were normal in both ventilation modes, and the entire process was as follows: Figure 10 As shown. After entering the leak self-test state, the first guidance interface 100 is displayed first. You can enter the second guidance interface 200 by clicking the second selection area 2b, or enter the third guidance interface 300 by clicking the start button 3, or enter the operation interface 500 by clicking the guide button 4.

[0132] If the user clicks the "continue" character in the first guidance interface 100, they will enter the third guidance interface 300. In the third guidance interface 300, they can click the second selection area 2b or continue to click the "continue" character to enter the second guidance interface 200, or click the guide button icon 4 to enter the operation interface 500.

[0133] If the user clicks the "continue" character in the third guidance interface 300, they will enter the second guidance interface 200. In the second guidance interface 200, they can click the first selection area 2a to enter the first guidance interface 100, or continue to click the "continue" character to enter the fourth guidance interface 400, or click the guide button icon 4 to enter the operation interface 500.

[0134] If the user clicks the "continue" character in the second guidance interface 200, they will enter the fourth guidance interface 400. In the fourth guidance interface 400, they can click the first selection area 2a to enter the first guidance interface 100, or click the guide button icon 4 to enter the operation interface 500.

[0135] In the second embodiment, the leak self-test results in both ventilation modes were generally abnormal. The entire process is as follows: Figure 11 As shown. After entering the leak self-test state, the first guidance interface 100 is displayed first. You can enter the second guidance interface 200 by clicking the second selection area 2b, or enter the third guidance interface 300 by clicking the start button 3, or enter the operation interface 500 by clicking the guide button 4.

[0136] If the user clicks the "continue" character in the first guidance interface 100, they will enter the third guidance interface 300. In the third guidance interface 300, they can click the second selection area 2b or continue to click the "continue" character to enter the second guidance interface 200, or click the "retry" character to return to the first guidance interface 100.

[0137] If the user clicks the "continue" character in the third guidance interface 300, they will enter the second guidance interface 200. In the second guidance interface 200, they can click the first selection area 2a to enter the first guidance interface 100, or continue to click the "continue" character to enter the fourth guidance interface 400, or click the guide button icon 4 to enter the operation interface 500.

[0138] If the user clicks the "continue" character in the second guidance interface 200, they will enter the fourth guidance interface 400. In the fourth guidance interface 400, they can click the first selection area 2a to enter the first guidance interface 100, or click the guide button 4 to enter the operation interface 500, or click the "retry" character to return to the second guidance interface 200.

[0139] As described above, if you keep clicking the "continue" button, you can complete a full leak self-test for both ventilation modes, thus providing users with a convenient and user-friendly interactive method to easily complete the necessary operations for gas leak self-testing.

[0140] In the above embodiments, after the veterinary anesthesia machine enters the leak self-check state, it will provide the user with guidance information for the selected test ventilation mode. This guidance information can be presented in various visual formats, making the guidance more intuitive for the user. Furthermore, the user can select the guidance information they wish to view, thus providing more comprehensive guidance. In addition, the veterinary anesthesia machine also provides users with a "quick entry" to frequently used operating interfaces, offering more choices and making the interaction process more user-friendly and easy to learn.

[0141] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
