Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to an interaction method for a ventilator, a ventilator, and a method of using it. Background Technology

[0002] In existing technology, if medical staff want to operate the cuff before or after using the voice valve, they must close the page containing the voice valve and find the page related to cuff operation. On the one hand, switching interfaces takes a considerable amount of time, resulting in a poor patient experience; on the other hand, if medical staff close the page containing the voice valve, they may accidentally activate other functions of the ventilator, potentially causing other complications for the patient.

[0003] Furthermore, without specific instructions on cuff operation, if healthcare workers forget to deflate the cuff or fail to fully deflate it before opening the voice valve, barotrauma may occur in the patient. Barotrauma primarily results from the patient's inability to exhale fully, leading to an abnormal increase in lung pressure, causing bradycardia, a violent cough response, and in more severe cases, pneumothorax and cardiac arrest, which can even be life-threatening. If, after closing the voice valve, healthcare workers fail to inflate the cuff correctly or inadequately, it may cause insufficient ventilation, a significantly increased risk of aspiration, inability to achieve effective positive airway pressure, ineffective triggering, tracheal mucosal ischemia, necrosis and damage, tracheal stenosis, tracheoesophageal fistula, tracheomalacia, tracheal rupture, patient discomfort and cough reflex, and cuff hernia formation. Summary of the Invention

[0004] This application mainly provides an interaction method for a ventilator, a ventilator, and a method of use, in order to solve the problem of poor ventilation safety caused by the use of a voice valve.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide an interaction method for a ventilator, the interaction method of which includes: adjusting the ventilator to a specific ventilation state and opening the voice valve activation page to enter the voice valve activation guidance process; performing a self-test before voice valve activation according to the voice valve activation guidance process; and activating the voice valve after completing the self-test.

[0006] In some embodiments, the voice valve activation guidance process includes an oxygenation and suctioning node and an airbag deflation node; the self-test before activating the voice valve according to the voice valve activation guidance process includes: displaying the oxygenation and suctioning node on the voice valve activation page and prompting to perform oxygenation and suctioning; in response to passing the oxygenation and suctioning node, displaying the airbag deflation node on the voice valve activation page and prompting to deflate the airbag; in response to passing the airbag deflation node, prompting to activate the voice valve on the voice valve activation page.

[0007] In some embodiments, the step of displaying the airbag deflation node and prompting for airbag deflation in response to the oxygenation suction node includes: displaying the airbag deflation node and prompting whether to adjust the airbag in response to the oxygenation suction node; and skipping the airbag deflation node in response to the non-adjustment command being triggered.

[0008] In some embodiments, the voice valve activation page displays the airbag deflation node and prompts for airbag deflation, further comprising: displaying the airbag deflation leakage rate monitoring value in real time on the voice valve activation page; and displaying a prompt message that the leakage rate is less than the leakage rate threshold on the voice valve activation page in response to the airbag deflation leakage rate monitoring value being less than the leakage rate threshold.

[0009] In some embodiments, the voice valve activation guidance process further includes an airbag inflation node; the ventilator interaction method further includes: after the voice valve is used, the voice valve activation page displays the airbag inflation node; in response to the airbag inflation node, the voice valve activation guidance process ends.

[0010] In some embodiments, the step of displaying the airbag inflation node on the voice valve enable page after the voice valve has been used is as follows: after the voice valve has been used, the airbag inflation node is displayed and a prompt is given as to whether to adjust the airbag; in response to the triggering of the command not to adjust the airbag, the airbag inflation node is skipped.

[0011] In some embodiments, the voice valve activation guidance process further includes a voice valve node; activating the voice valve includes: in response to completing a self-test, the voice valve activation page displays the voice valve node; after inserting the voice valve, a timing command is triggered, and the voice valve activation page displays the preset timing duration and the current timing duration of the voice valve.

[0012] In some embodiments, after the voice valve activation page displays the preset timing duration and the current timing duration of the voice valve, it further includes: in response to the triggering of the end timing command, displaying the actual usage duration of the voice valve and displaying a prompt message confirming the removal of the voice valve; removing the voice valve to complete the use of the voice valve.

[0013] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a ventilator, which is used to implement the steps of the ventilator interaction method described above.

[0014] The beneficial effects of this application are as follows: Unlike existing technologies, this application discloses an interaction method for a ventilator, a ventilator, and a method of use. By adjusting the ventilator to a specific ventilation state and opening the voice valve activation page, the user enters the voice valve activation guidance process. The same page integrates the voice valve switch, cuff inflation / deflation buttons, and prompts, allowing medical staff to complete the operation without switching pages, significantly shortening operation time and improving the continuity of treatment and experience for critically ill patients. Centralizing related functions reduces the complexity of the operation path and lowers the risk of patient complications due to misoperation. A self-check is performed before activating the voice valve according to the voice valve activation guidance process, avoiding risks caused by medical staff forgetting steps, automatically adapting to the device status, reducing manual judgment costs, and allowing medical staff to focus more on patient condition observation and treatment decisions. After completing the self-check, the voice valve is activated. This effectively solves the problems of lack of management, cumbersome operation, and insufficient risk control in the voice valve usage process of existing technologies, achieving seamless integration of voice valve function and patient airway management.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] See Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the interaction method for a ventilator provided in this application. The interaction method for the ventilator includes the following steps:

[0029] 10: Adjust the ventilator to a specific ventilation state and open the voice valve activation page to enter the voice valve activation guide process.

[0030] After powering on, medical staff determine that ventilation is required and select a ventilation mode that supports voice valve function.

[0031] A specific ventilation mode is a ventilation mode that healthcare professionals select based on the patient's needs after the ventilator is turned on, enabling the voice valve function. The voice valve module can only be activated in a specific ventilation mode, providing the necessary conditions for subsequent operations such as voice valve activation, cuff management, oxygenation, and suctioning.

[0032] The voice valve activation page integrates all voice valve-related steps, such as oxygenation and suctioning, cuff deflation, voice valve operation, and cuff inflation. Visual step-by-step guidance and function buttons simplify operations for medical staff and prevent misoperations caused by switching between pages.

[0033] 20: Perform a self-test before activating the voice valve according to the voice valve activation guide.

[0034] After activating the voice valve function module, the interface displays a self-test guide before the voice valve is activated. Medical staff follow the guide to interact with the ventilator and complete the operation.

[0035] Specifically, the voice valve activation guidance process includes the oxygenation and suctioning stage and the airbag deflation stage.

[0036] See Figure 2 Furthermore, step 20 also includes the following steps:

[0037] 21: The voice valve activation page displays the oxygenation and suction node and prompts you to perform oxygenation and suction.

[0038] When not activated, all steps are displayed in gray; once activated, the oxygenation and suctioning node will be highlighted in blue, becoming the first operable node. Oxygenation and suctioning is the first essential self-check step before the voice valve is activated, and it is the starting point of a one-way process that cannot be skipped.

[0039] The page displays function buttons such as "sputum suction" and "oxygenation". Medical staff can click to complete the corresponding operation. After the operation is completed, the node status is updated, such as turning gray or being marked "completed".

[0040] The oxygenation and suctioning stage is a pre-treatment step used to clear the patient's airway and supplement oxygen. It ensures the airway is clear and blood oxygen is adequate before the voice valve is activated, reducing the risk of hypoxia or airway damage during use.

[0041] See Figure 3 , Figure 3 This is a schematic diagram of an embodiment of the voice valve activation page displaying the oxygenation and suction node.

[0042] The oxygenation and suctioning node displays the prompt message "Please perform thorough suctioning of the patient's airway and glottis," as well as an oxygenation operation button and a "Next" button to end the node and proceed to the next node.

[0043] 22: In response to the oxygenation and suction node, the voice valve activation page displays the airbag deflation node and prompts you to deflate the airbag.

[0044] After the oxygenation and suctioning procedure is completed, the inflator deflator procedure will begin, which will turn blue and be highlighted. Inflator deflator is a core safety step before the voice valve is activated. It is located after oxygenation and suctioning and before the voice valve is activated or deactivated, and must be manually confirmed before execution.

[0045] The airbag deflation point is an operational step used to release the gas inside the endotracheal tube airbag, preventing the airbag from compressing the airway and causing barotrauma when the voice valve is activated.

[0046] See Figure 4 , Figure 4 This is a schematic diagram of an embodiment of the voice valve activation page displaying the airbag deflation node.

[0047] Includes a diagram showing the location of the airbag inside the human body, a "deflator" button, and the text message "Please slowly and completely deflate the airbag," a "previous step" button to return to the previous node, and a "next step" button to end the current node and proceed to the next node.

[0048] The oxygenation and suctioning nodes and the airbag deflation nodes achieve standardized self-checks before the voice valve is activated through one-way process control and clear prompt text, reducing the risk of medical staff operation errors and ensuring patient safety.

[0049] Furthermore, step 22 also includes the following steps:

[0050] 221: In response to the oxygenation and suction node, the voice valve activation page displays the airbag deflation node and prompts whether to adjust the airbag.

[0051] After the oxygenation and suctioning procedure is completed, the system automatically enters the airbag deflation procedure. At this time, the interface will provide medical staff with a prompt to determine whether the airbag needs to be adjusted.

[0052] If deflation is required, the interface will display further operation prompts and simultaneously display a "Deflate" button. Medical staff can click on the button to control the deflation of the airbag until it is completely emptied.

[0053] Clearly inform medical staff about the current need for balloon management procedures, allowing them to manually determine whether to deflate the balloon to avoid the risk of misoperation caused by automatic deflation, while simplifying the operation steps with visual buttons.

[0054] 222: In response to the airbag not adjusting command being triggered, skip the airbag deflation node.

[0055] The system automatically skips cases where the cuff management function is malfunctioning, avoiding unnecessary operations. Manual skipping is determined by medical staff based on clinical needs; for example, if the patient's airway condition does not require deflation, it ensures operational flexibility. After skipping the cuff deflation step, the process directly proceeds to the voice valve step, i.e., the voice valve is inserted and the timer begins, without needing to return or complete the deflation step.

[0056] The adjustment prompts for the airbag deflation point guide medical staff to complete airbag management safely by determining whether deflation is needed and providing visual operation buttons. The skip logic combines automatic system detection with manual intervention, taking into account both functional usability and clinical flexibility, ultimately achieving an efficient and safe voice valve activation process.

[0057] Optionally, step 22 may also include the following steps:

[0058] 223: The real-time leakage rate monitoring value of the airbag is displayed on the voice valve activation page.

[0059] In the airbag deflation node of the voice valve activation process, when medical staff click the "deflate" button to deflate the airbag, the system monitors the gas leakage level of the airbag in real time and dynamically displays the "leakage rate" value on the operation interface.

[0060] The leakage rate is the proportion of gas leaked during airbag deflation, used as a quantitative indicator to determine whether the airbag has been completely deflated. Real-time monitoring ensures complete deflation, avoids abnormal airway pressure caused by residual gas, and provides alerts to strengthen safety verification.

[0061] See Figure 4 The leakage rate monitoring value is displayed synchronously with the "de-inflate" button, located in the airbag deflation operation area. It provides intuitive feedback on whether the airbag has been completely deflated, helping medical staff to determine whether the airbag has been "completely deflated" and avoid barotrauma caused by incomplete deflation when the patient uses the voice valve later, such as pneumothorax or bradycardia due to abnormally high intrapulmonary pressure.

[0062] 224: In response to the leakage rate monitoring value of the airbag being less than the preset leakage rate threshold, a prompt message indicating that the leakage rate is less than the leakage rate threshold is displayed on the voice valve activation page.

[0063] When the real-time monitored leakage rate is lower than the preset threshold, the system automatically triggers a prompt mechanism. This reminds medical staff that the current deflation of the cuff has not reached the safety standard and further confirmation or reoperation is required. This prevents abnormal airway pressure in patients during the use of the voice valve due to residual gas in the cuff, reducing the risk of complications.

[0064] 23: In response to the airbag deflation node, the voice valve activation page prompts you to enable the voice valve.

[0065] Once the airbag deflation step is completed, the system automatically enters the voice valve activation determination stage. The "Voice Valve Node" on the voice valve activation page turns blue and is highlighted, while other incomplete steps remain gray, forming a process guide that prompts medical staff to "determine whether to insert the voice valve based on the patient's condition."

[0066] 30: After completing the self-test, activate the voice valve.

[0067] After the above self-check conditions are met, the voice valve is activated. Once oxygenation and suctioning are complete and the cuff deflation step is passed, the system automatically jumps to the "Voice Valve" step, which is highlighted in blue on the interface. Medical staff decide whether to insert the voice valve based on the patient's real-time status, such as level of consciousness and communication needs.

[0068] Optionally, the voice valve activation guidance process also includes a voice valve node.

[0069] See Figure 5 Step 30 also includes the following steps:

[0070] 31: In response to the completion of the self-test, the voice valve enable page displays the voice valve node.

[0071] After medical staff complete the two self-check steps of oxygenation and suctioning and cuff management before activating the voice valve, the system automatically activates and displays the "voice valve node" on the voice valve activation page, guiding medical staff to perform the voice valve activation operation. On the voice valve activation page, the "voice valve node" changes from gray to blue and highlights, displaying the "Start" button, indicating that the activation operation can be performed.

[0072] Self-check refers to the oxygenation, suctioning, and cuff management procedures before the voice valve is activated. It is a preliminary step to ensure patient safety. It ensures that the patient's airway is clear and the cuff is in a safe condition, avoiding complications such as hypoxia and barotrauma after the voice valve is activated.

[0073] The voice valve node is the third core step in the voice valve activation process, corresponding to the "open / stop voice valve" operation. As a key operation node after self-check, it follows the safety preparation steps, activates the patient's voice function, and enables communication under ventilator support.

[0074] The node display shows the dynamic changes in the status of each step in the interface, providing intuitive feedback on the progress of the process and ensuring that medical staff complete the operation in sequence, avoiding the omission of key steps.

[0075] By completing a self-check as a prerequisite, the system ensures that the patient's airway is clear and the cuff is in a safe condition before the voice valve is activated, thus eliminating risks caused by insufficient preparation. The highlighted "voice valve node" clearly indicates the next operational goal, reducing the decision-making burden on medical staff, especially suitable for emergency clinical scenarios. The voice valve activation and pre-check steps are completed on the same page, eliminating the need to switch interfaces, shortening operation time, and improving the treatment experience for critically ill patients.

[0076] 32: After inserting the voice valve, a timing command is triggered. The voice valve activation page displays the preset timing duration and the current timing duration of the voice valve.

[0077] When medical staff click the "Start" button on the voice valve activation page, the system receives the "Activate Voice Valve" command and simultaneously triggers the timing function. The button status changes from "Start" to "Stop," visually indicating that the timing has started, and the patient can speak through the voice valve.

[0078] The preset timing duration is the maximum safe usage time of the voice valve per operation, pre-defined by the system. It is displayed next to the timing area, either as a number or a progress bar, serving as a reference upper limit for medical staff. This helps prevent prolonged use of the voice valve, which could lead to patient hypoxia or airway damage, and ensures standardized operation duration.

[0079] The current timer duration is the cumulative usage time from clicking "Start" to the current moment, accurate to the second. It dynamically refreshes in the center of the interface or below the timer button; for example, "00:45" indicates 45 seconds have been used. Real-time feedback on the voice valve's usage progress helps medical staff manage communication time and stop the activity promptly to ensure patient safety.

[0080] See Figure 6 , Figure 6 This is a schematic diagram of an embodiment of displaying the voice valve node on the voice valve activation page.

[0081] When the voice valve is enabled and the voice valve node is displayed on the page, the voice valve node is highlighted. The page includes a diagram of the voice valve's location, the text prompts "Insert the data trigger into the loop between the flow sensor and the patient. Reconnect the data trigger to the patient. Click [Start] to start the voice valve timing function." and "Click [Stop] to end the voice valve timing function."

[0082] The page also includes the total timing duration "30.0 min" and the current timing duration "03:02:06".

[0083] The page also includes a "Start" button to control the start of the timer. After the timer starts, the "Start" button will change to a "Stop" button to control the end of the timer.

[0084] Optionally, see Figure 7After step 30, the following steps are also included:

[0085] 40: In response to the end-of-time command being triggered, display the actual usage time of the voice valve and display a prompt message confirming the removal of the voice valve.

[0086] The interface stops timing and displays the cumulative usage time from "start" to "stop", such as "01:20" indicating that it was actually used for 1 minute and 20 seconds, for medical staff to record and evaluate.

[0087] The end-of-time command is a system instruction triggered by medical staff clicking the "Stop" button, used to terminate the voice valve's activation. Clearly defining the end time for voice valve use is crucial to prevent prolonged use that could lead to patient hypoxia or airway damage.

[0088] Actual usage time is the cumulative time from activation to deactivation of the voice valve, accurate to the second.

[0089] The prompt message confirming the removal of the voice valve is a text guide that pops up after the system finishes timing, reminding medical staff to physically remove the voice valve. This prevents the risk of airway obstruction due to forgetting to remove the voice valve, ensures smooth transition to subsequent cuff inflation, and guarantees a closed-loop process.

[0090] 50: Remove the voice valve to complete the use of the voice valve.

[0091] Following the on-screen instructions, medical staff manually remove the voice valve device from the patient's airway. After removal, clicking the "Inflate" button re-inflates the cuff, restoring normal ventilation. This completes the voice valve usage process.

[0092] By embedding "removing the voice valve" as a mandatory step into the process, the safety logic of "activation-timing-stopping-removal-inflation" is ensured for every use of the voice valve, thereby improving the standardization of medical operations.

[0093] Optionally, the voice valve activation guidance process also includes an airbag inflation node.

[0094] The airbag inflation step is the fourth core step in the voice valve usage process, used to re-inflate the airbag after the voice valve has been deactivated. Ensure the airbag seals the airway promptly after removing the voice valve to prevent complications such as insufficient ventilation, aspiration, and airway leakage.

[0095] See Figure 8 , Figure 8 This is a schematic diagram of an embodiment of the voice valve activation page displaying the airbag inflation node.

[0096] When the voice valve is enabled and the airbag inflation node is displayed on the page, the airbag inflation node will be highlighted.

[0097] See Figure 9After step 30, the following steps are also included:

[0098] 60: After the voice valve is used, the voice valve activation page displays the airbag inflation node.

[0099] When medical staff remove the voice valve and trigger the "stop" command, the system automatically activates and displays the "airbag inflation node" on the voice valve activation page. The "airbag inflation node" on the voice valve activation page changes from gray to highlighted, entering the inflation process and guiding medical staff to re-inflate the patient's airbag and restore normal ventilation.

[0100] Optionally, the airbag inflation node displays the current airbag pressure value in real time.

[0101] See Figure 8 When the voice valve is enabled and the airbag inflation node is displayed on the page, the airbag inflation node is highlighted, and the page displays a diagram of the airbag location again, along with the text prompt "Remove the voice valve and inflate the airbag. Reconnect the circuit to the patient." The airbag inflation node displays the current "airbag pressure" as "30.0" in real time.

[0102] Inflation of the cuff is a crucial step in restoring airway seal; failure to do so can lead to ventilator leaks, insufficient tidal volume, and even aspiration pneumonia. The inflation process is seamlessly integrated with the voice valve deactivation procedure, all completed via a single button on the same page, significantly shortening rescue time, especially for critically ill patients. Highlighted nodes and accompanying text prompts ensure healthcare workers follow the inflation procedure precisely, preventing medical errors caused by busyness or forgetfulness.

[0103] By deactivating the voice valve, activating the inflation node, and synchronizing the pressure inflation, the airbag management function is deeply integrated into the entire process of voice valve use. This fundamentally solves the defect in existing technologies where airbag operation requires switching between pages, ultimately achieving a "safe, efficient, and standardized" closed-loop voice valve usage.

[0104] Furthermore, step 60 also includes the following steps:

[0105] 61: After using the voice valve, the airbag inflation node will be displayed and a prompt will appear asking whether to adjust the airbag.

[0106] After medical staff remove the voice valve and click the "Stop" button, the system automatically proceeds to the final step of the voice valve usage process: airbag inflation. The interface displays this step and prompts whether to adjust the airbag. On the voice valve activation page, the "Airbag Inflation" step changes from gray to blue highlight, indicating that this step is operable. An "Inflate" button is also provided to guide medical staff in inflating the airbag.

[0107] The system displays text instructions at the inflation stage, asking medical staff whether the balloon inflation procedure needs to be performed. This clear prompt reinforces medical staff's awareness of the balloon's status, preventing patient safety risks due to forgetting to inflate the balloon.

[0108] 62: In response to the airbag inflation command being triggered, skip the airbag inflation node.

[0109] Based on the patient's condition, such as short-term lack of ventilation support or abnormal cuff function, medical staff determine "no inflation required" and trigger the "do not adjust cuff" command upon interface prompt. After the medical staff selects "do not adjust cuff," the system skips the inflation operation, and the cuff inflation node status changes to "skipped." All steps on the voice valve activation page return to their initial state, awaiting the next activation, completing the entire closed-loop process.

[0110] The manual triggering command by healthcare professionals to skip the balloon inflation process empowers them to make flexible decisions based on clinical realities, avoiding discomfort caused by forced inflation. It simplifies unnecessary procedures, improves process flexibility, and ensures traceability through node status markers.

[0111] The "adjustment prompts" ensure that no inflation steps are missed, while the "no-adjustment instructions" allow for flexible operation in special scenarios, avoiding excessive intervention.

[0112] It achieves a balance between standardization and personalization in airbag inflation operation, ultimately solving the problem of disconnect between airbag management and voice valve operation in existing technologies, and reducing the risk of complications.

[0113] 70: In response to the airbag inflation node, the voice valve activation guidance process ends.

[0114] Medical staff click the "Inflate" button on the voice valve activation page, and the system controls the airbag to inflate to the preset pressure value. Once inflation is complete, the button status changes to "Completed". After the airbag inflation is successfully completed, the system ends the voice valve activation guidance process, achieving a closed loop for the entire process.

[0115] The completion of the airbag inflation stage ensures that the patient's airway is restored to a sealed state, avoiding risks such as insufficient ventilation and aspiration, and physically ensuring the safety of the final stage; at the same time, the process status reset avoids medical staff from repeating operations or missing steps.

[0116] A ventilator for implementing the steps of the ventilator interaction method as described above.

[0117] This ventilator implements interactive methods and steps through integrated functional modules and a streamlined interface design. Its core structure includes functional module integration, interface design, and process control logic.

[0118] Specifically, the voice valve function module integrates the voice valve operation module to control the opening / stop and timing of the voice valve; the oxygenation and suction operation module provides suction and oxygenation function buttons and prompts; and the airbag management function module realizes airbag deflation / inflation control.

[0119] A method of using a ventilator, the method of using a ventilator as described above.

[0120] The ventilator usage instructions use an integrated self-test process to avoid the drawbacks of traditional workflows that require switching between pages, reducing the operation time for medical staff and lowering the risk of misoperation.

[0121] By linking airbag management with voice valve operation, the problem of "disconnection between airbag management and voice valve" is solved, ensuring the safety of the airbag status before and after the use of the voice valve.

[0122] Unlike existing technologies, this application integrates voice valve operation, oxygenation and suctioning, and cuff management into a single entry point: the voice valve activation page. The module is activated and deactivated via a function switch. Once activated, it follows a one-way flow: oxygenation and suctioning, cuff deflation, voice valve activation, and cuff inflation. This improves operational safety and reduces the risk of complications. All operations are completed on a single page, eliminating the cumbersome steps of searching for the cuff operation entry point after closing the voice valve in traditional procedures. This saves time for medical staff, and the one-way flow design and display prompts reduce the complexity of manual operation and minimize complications caused by incorrect switching of ventilation modes. The integrated process reduces the time spent by medical staff, minimizes patient discomfort before and after voice valve use, and the timing function helps medical staff to rationally schedule voice communication, avoiding excessive consumption of patient energy and indirectly promoting recovery.

[0123] During cuff deflation, leakage rate monitoring and complete deflation prompts ensure thorough deflation, resolving the issue of abnormally high intrapulmonary pressure caused by incomplete deflation. Forced cuff inflation after the voice valve is deactivated ensures pressure reaches the target level through parameter synchronization, preventing airway seal failure due to inflated cuffs. Simultaneously, mandatory prompts and operation during oxygenation and suction reduce airway damage caused by sputum obstruction or insufficient humidification.

[0124] By integrating functional modules, standardizing process steps, and implementing real-time safety monitoring, the core solution addresses the shortcomings of existing ventilator voice valve functions, such as disconnected cuff management, cumbersome operation, and high safety risks. Ultimately, this achieves the technical goals of reducing medical staff misoperation, lowering the risk of patient complications, and improving clinical efficiency.

[0125] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
