Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a ventilation device. Background Art

[0002] Human respiration refers to the periodic and rhythmic inhalation and exhalation of gases, absorbing oxygen and discharging carbon dioxide, thereby achieving gas exchange. For patients who are unable to breathe independently, external devices such as ventilators are required to provide respiratory support to the patients. For patients who need to undergo major surgical operations, external devices such as anesthetic machines are also required to provide respiratory support to the patients while ensuring inhalation of the anesthetic machine. With the support of mechanical ventilation, the airway is maintained unobstructed, ventilation and oxygenation are improved, and the body is prevented from lacking oxygen and accumulating CO2. During the operation, if the mechanical ventilation stops abnormally or the machine delivers gas abnormally and is not discovered in time, it may cause the patient to suffocate for a long time, which will directly affect the safety of the patient.

[0003] Currently, anesthetic machines on the market are generally equipped with a display screen. This design aims to provide clinicians with key parameters and real-time images during the anesthetic process to facilitate monitoring and adjusting the depth of anesthesia and the vital signs of the patient. However, with the rapid progress of medical technology and the increasingly diverse clinical needs, the configuration of a single display screen gradually shows limitations. In clinical practice, doctors often need to quickly identify and respond to specific physiological changes of the patient or respiratory control parameters of the anesthetic state, and these parameter information may not be easily obtained quickly in the complex data stream. In addition, considering various fault situations that may occur during the operation of medical devices, as the main interface for information display of the anesthetic machine, once a single display screen fails or malfunctions, it may lead to the loss or misreading of key information, affecting the treatment process of the patient and lacking data basis for dealing with fault handling.

[0004] Therefore, to meet the diverse needs of clinical practice, how to intuitively obtain the key control parameters of the ventilation state and the immediacy of dealing with display failures is an urgent problem to be solved currently. Summary of the Invention

[0041] The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0042] Figure 1 It is a schematic structural diagram of a ventilation device provided by an embodiment of the present application. As Figure 1As shown, the ventilation device provided in this embodiment at least includes a breathing circuit assembly 10, one or more sensors 20, one or more monitoring devices 30, a processor 40, a main display 50, and an auxiliary display 60.

[0043] In this embodiment, the breathing circuit assembly 10 is used to provide gas input to the patient and / or discharge the exhaled gas of the patient. It should be noted that the gas provided by the breathing circuit assembly 10 to the patient can be the gas generated inside the ventilation device. For example, the ventilation device provides the gas for the patient's breathing through the internal gas source, such as providing the gas transported to the patient through the built-in turbine; the gas provided by the breathing circuit assembly 10 to the patient can also be from an external gas source.

[0044] Generally, at least one sensor 20 is equipped in the ventilation device, which is used to collect at least one type of first data characterizing the patient's ventilation state and the breathing circuit state on the breathing circuit assembly 10. For example, a gas flow sensor, this type of sensor is used to monitor the patient's breathing condition, real-time detect the gas flow rate in the ventilation pipeline, and calculate the corresponding gas flow according to the area of the ventilation pipeline and the detected gas flow rate. A pressure sensor, this type of sensor is used to monitor the pressure in the breathing circuit, convert the airway pressure into a differential signal, and hand the measured value to the processor 40 to accurately make inhalation and exhalation judgments. Then, the processor 40 issues an instruction to control the air inlet pump to increase or decrease the pipeline pressure.

[0045] One or more monitoring devices 30 are also equipped in the ventilation device, which are used to monitor the second data characterizing the patient's breathing state and physiological indicators. For example, an oxygen concentration monitoring device, this device converts the concentration of the measured gas into an electrical quantity output in a certain relationship through a gas sensor, and is used to monitor the oxygen concentration of the gas in the airbag to ensure that the patient inhales enough concentration of oxygen and maintains normal oxygenation. An end-tidal carbon dioxide concentration monitoring device, this device is based on the Lambert-Beer law, finds the corresponding relationship between the gas concentration and the attenuation amount of infrared light, and calculates the concentration of the corresponding gas according to the measured infrared light attenuation amount, and is used to detect the carbon dioxide concentration of the gas in the airbag, reflect the patient's lung function and ventilation efficiency, and help to timely detect problems such as respiratory dysfunction and ventilation insufficiency.

[0046] The processor 40 is at least used to acquire the first data and the second data, and perform data processing on the first data and the second data to generate ventilation parameters and vital sign parameters characterizing the current state of the patient. Among them, the ventilation parameters include at least one of a resistance value, compliance, respiratory rate, and ventilation volume, and these data reflect the operating state of the ventilation device and the respiratory mechanics characteristics of the patient. The vital sign parameters include at least one of pulse oximetry, inspired oxygen concentration, end-tidal carbon dioxide, heart rate, and blood pressure, and these data are obtained through a physiological monitoring device or an external vital sign monitoring system connected to the ventilation device and are used to evaluate the overall physiological state of the patient. After acquiring the first data and the second data, the processor 40 will perform a series of data processing operations to generate the required ventilation parameters and vital sign parameters. For example, perform row filtering and denoising processing on the original data, and then extract the characteristic parameters related to ventilation and vital signs, such as changes in respiratory rate, fluctuations in blood pressure, etc. Based on the extracted characteristic parameters, further data analysis and calculation are performed to generate ventilation parameters and vital sign parameters. For example, evaluate the ventilation efficiency of the patient by calculating the ratio of tidal volume to respiratory rate.

[0047] The main display 50 is used to display the ventilation parameters, vital sign parameters, and device operating parameters under the control of the processor 40; the device operating parameters include at least one of a ventilation mode, a working mode, gas control parameters, and alarm parameters. The main display 50 of the ventilation device can display a variety of key information under the control of the processor 40 to meet the needs of clinical monitoring and management. These information are for evaluating the respiratory state of the patient, adjusting the ventilation settings, and ensuring the normal operation of the device.

[0048] The auxiliary display 60 is used to display some of the ventilation parameters, vital sign parameters, and / or device operating parameters under the control of the processor 40; and when the main display 50 has a display failure, the parameter information displayed by the auxiliary display 60 is used to provide operation guidance and / or emergency treatment basis for the respiratory support of the patient.

[0049] In this embodiment, compared with common ventilation devices, an auxiliary display 60 is additionally provided. Under the control of the processor 40, the auxiliary display 60 displays some of the ventilation parameters, vital sign parameters, and / or device operation parameters. That is to say, the data displayed on the auxiliary display 60 is a part of the data displayed on the main display 50. Compared with common ventilation devices equipped only with the main display 50, those devices additionally equipped with the auxiliary display 60 have more flexibility and expandability in terms of function and information display. As a supplement to the main display 50, the data displayed on the auxiliary display 60 is a subset of the data on the main display 50. According to clinical needs or device design, key or secondary information can be selectively displayed. It can effectively solve the problem that in clinical practice, doctors often need to quickly identify and respond to specific physiological changes or respiratory control parameters of the anesthetic state of patients, and these parameter information may not be easily obtained quickly in the complex data stream. Especially in emergency situations, the auxiliary display 60 can quickly switch to display the most important vital sign parameters so that medical staff can quickly obtain key information.

[0050] At the same time, the auxiliary display 60 in this embodiment can also, when the main display 50 has a display failure, use the parameter information displayed on the auxiliary display 60 to provide operation guidance and / or emergency treatment basis for the respiratory support of the patient. It can be understood that due to various reasons such as hardware failure, software problems, or power interruption, the main display 50 cannot display normally. At this time, the auxiliary display 60 can continue to display key ventilation parameters, vital sign parameters, and / or device operation parameters, which provide important clues about the patient's respiratory status and the operation status of the ventilation device. In the case of a failure of the main display 50, medical staff can rely on the parameter information displayed on the auxiliary display 60 to guide the respiratory support operation of the patient. For example, if the ventilation parameters show that the patient's tidal volume is insufficient or the respiratory rate is too fast, medical staff can timely adjust the settings of the ventilation device to improve the patient's ventilation condition. Similarly, if the vital sign parameters show that the patient's blood oxygen saturation has decreased, medical staff can take corresponding first aid measures, such as increasing oxygen supply or adjusting the ventilation strategy.

[0051] Therefore, the additional provision of the auxiliary display 60 not only improves the information visualization and focus of the ventilation device, enhances the emergency handling ability, but also improves the clinical decision-making efficiency, enhances the safety and reliability of the ventilation device, provides a more efficient and convenient working experience for medical staff, and at the same time ensures the safety of patients.

[0052] In summary, the ventilation device provided in this embodiment includes a breathing circuit assembly, one or more sensors and monitoring devices, a processor, a main display, and an auxiliary display; wherein, the breathing circuit assembly is used to provide gas input to the patient and / or discharge the exhaled gas of the patient; the sensor is used to collect at least one type of first data characterizing the ventilation state of the patient and the state of the breathing circuit; the monitoring device is used to monitor second data characterizing the breathing state and physiological indexes of the patient; the processor is at least used to obtain the first data and the second data, and perform data processing on the first data and the second data to generate ventilation parameters and vital sign parameters characterizing the current state of the patient; the main display is used to display the ventilation parameters, the vital sign parameters, and the device operation parameters under the control of the processor; the auxiliary display is used to display some of the ventilation parameters, the vital sign parameters, and / or the device operation parameters under the control of the processor; and when a display failure occurs in the main display, the parameter information displayed on the auxiliary display is used to provide operation guidance for respiratory support and / or a basis for emergency treatment for the patient.

[0053] In this application, by additionally equipping a conventional ventilation device with an auxiliary display, which selectively displays some of the ventilation parameters, vital sign parameters, and / or device operation parameters that need special attention displayed on the main display under the control of the processor, the data readability and system reliability of the ventilation device are improved; at the same time, when a display failure occurs in the main display, important parameters regarding the patient's breathing state and the operation state of the ventilation device can be obtained in a timely manner through the auxiliary display, providing operation guidance for respiratory support and / or a basis for emergency treatment for the patient, providing a basis for emergency treatment and optimizing the operation experience for medical staff, enhancing patient safety, improving clinical decision-making efficiency, and ensuring the safety and reliability of the ventilation device.

[0054] Figure 2 FIG. is a schematic structural diagram of a breathing circuit assembly provided in another embodiment of this application. In some embodiments, the ventilation device can be a ventilator, which is an artificial mechanical ventilation device used to assist or control the patient's spontaneous breathing movement to achieve the function of gas exchange in the lungs, reduce the body's consumption, and facilitate the recovery of respiratory function. As Figure 2 shown, in this embodiment, the breathing circuit assembly 10 at least includes one or more gas sources 101, a breathing circuit 102, and a breathing controller 103.

[0055] In some embodiments, the breathing circuit 102 can include an inhalation branch 11a, an exhalation branch 11b, a gas source interface 12a, and a breathing interface 12b, and the breathing controller 103 can include an inhalation controller 13a and an exhalation controller 13b.

[0056] In this embodiment, the gas source interface 12a is used to connect to a gas source (not shown in the figure), and the gas source is used to provide gas, which is usually oxygen, or a mixed gas of oxygen and air, etc.; the gas source can be a gas source inside the ventilation device or an external gas source, and the external gas source is, for example, a compressed gas cylinder or a central gas supply source.

[0057] The breathing interface 12b is used to connect the patient to the inhalation branch 11a and the exhalation branch 11b. The breathing interface 12b can introduce the gas transmitted from the inhalation branch 11a into the patient, and can also introduce the gas exhaled by the patient into the exhaust interface 12c through the exhalation branch 11b. In some embodiments, the breathing interface 12b can be a nasal cannula or a mask for wearing on the mouth and nose, which can be determined according to actual needs.

[0058] The inhalation branch 11a is connected between the breathing interface 12b and the gas source interface 12a, and is used to provide gas for the patient, such as oxygen or air. For example, the gas input from the gas source interface 12a enters the inhalation branch 11a, and then enters the patient's lungs through the breathing interface 12b. In some embodiments, an inhalation controller 13a is disposed on the inhalation branch 11a, and is used to control the gas delivered from the gas source interface 12a to the patient through the inhalation branch 11a. For example, according to the instruction of the processor 40, the inhalation branch 11a is turned on or off, or the flow rate or pressure of the gas in the inhalation branch 11a is controlled. In some embodiments, the inhalation controller 13a can include one or more devices such as an inhalation valve, a one-way valve, or a flow controller that can achieve flow or pressure control.

[0059] The exhalation branch 11b is connected between the breathing interface 12b and the exhaust interface 12c, and is used to export the gas exhaled by the patient to the exhaust interface 12c. In some embodiments, an exhalation controller 13b is disposed on the exhalation branch 11b, and is used to turn on or off the exhalation branch 11b according to the instruction of the processor 40, or to control the flow rate or pressure of the gas exhaled by the patient. In some embodiments, the exhalation controller 13b can include one or more devices such as an exhalation valve, a one-way valve, or a flow controller that can achieve flow or pressure control.

[0060] Figure 3 It is a schematic structural diagram of a breathing circuit assembly provided by another embodiment of the present application. In some embodiments, the ventilation device can also be an anesthesia machine. An anesthesia machine is a medical device designed specifically for surgical or medical operations, mainly used to provide precise oxygen and anesthetic gas mixture delivery for patients during general anesthesia, assist or control the patient's breathing, and simultaneously monitor vital signs in real time to ensure safety. Its core functions include not only ventilation support, but also precise management of anesthetic drugs and comprehensive monitoring of the patient's physiological state.

[0061] As Figure 3As shown, in this embodiment, the breathing circuit assembly 10 includes at least one or more gas sources 101, a breathing circuit 102, and an auxiliary component 104.

[0062] In some embodiments, the breathing circuit 102 may include an inhalation branch 15a, an exhalation branch 15b, a gas source interface 16a, a breathing interface 16b, a breathing assistance component 17, and an anesthetic output component 18. In some embodiments, the breathing circuit 102 may further include a gas recovery component 19.

[0063] In this embodiment, the gas source interface 16a is used to connect to a gas source (not shown in the figure), and the gas source is used to provide gas. In one embodiment, the gas provided by the gas source may be oxygen, nitrous oxide (laughing gas), and / or air, etc.

[0064] The breathing assistance component 17 is used to provide power for the patient's involuntary breathing and maintain airway patency. In some embodiments, the breathing assistance component 17 controls the gas provided by the gas source to be delivered to the patient through the inhalation branch 15a. In some specific embodiments, the breathing assistance component 17 mixes the fresh gas input from the gas source interface 16a, the gas exhaled by the patient in the exhalation branch 15b, and the anesthetic drug output by the anesthetic output component 18 and then outputs it to the breathing interface 16b through the inhalation branch 15a to drive the patient to inhale, and receives the gas exhaled by the patient through the exhalation branch 15b.

[0065] The anesthetic output component 18 is used to provide anesthetic drugs. Usually, the anesthetic drugs are mixed into the fresh air introduced from the gas source interface 16a in the form of gas and are delivered to the breathing circuit together. In some specific embodiments, the anesthetic output component 18 can be implemented by an anesthetic vaporizer. The anesthetic is usually in liquid form and is stored in the anesthetic vaporizer. Optionally, the anesthetic vaporizer may include a heating device for heating the anesthetic to make it volatilize and generate anesthetic vapor. The anesthetic output component 18 is connected to the pipeline of the gas source interface 16a, and the anesthetic vapor is mixed with the fresh air introduced from the gas source interface 16a and then delivered to the inhalation branch 15a together.

[0066] In some embodiments, the inhalation branch 15a and the exhalation branch 15b are connected to form a closed loop, and the gas recovery component 19 is arranged on the pipeline of the exhalation branch 15b. The mixed gas of fresh air introduced from the gas source interface 16a is input from the inlet of the inhalation branch 15a and provided to the patient through the breathing interface 16b arranged at the outlet of the inhalation branch 15a; in some embodiments, the breathing interface 16b can be a face mask, a nasal cannula, or an endotracheal tube. The inlet of the exhalation branch 15b is connected to the breathing interface 16b. When the patient exhales, the exhaled gas enters the gas recovery component 19 through the exhalation branch 15b, and the carbon dioxide in the exhaled gas is filtered by the substance in the gas recovery component 19, and the gas after filtering carbon dioxide is recycled into the inhalation branch 15a.

[0067] Based on the fact that when a display failure occurs on the main display 50, the parameter information displayed on the auxiliary display 60 is used to provide operation guidance for the patient's respiratory support and / or a basis for emergency treatment.

[0068] Therefore, in some embodiments, the processor 40 is further configured to output a corresponding alarm message when it monitors that the main display 50 shows an abnormality, and control the auxiliary display 60 to display the alarm message; wherein, the abnormality of the main display 50 includes at least one of an abnormality of the ventilation device and a mechanical failure of the main display.

[0069] It can be understood that the abnormality of the ventilation device may be caused by internal failures of the ventilation device, sensor failures, incorrect parameter settings, etc. When these abnormal situations occur, the processor 40 may not be able to obtain correct ventilation parameters, vital sign parameters, and / or device operation parameters, thereby causing the main display 50 to be unable to correctly display the ventilation parameters, vital sign parameters, and / or device operation parameters during the operation of the ventilation device. The main display 50 itself may have mechanical failures, such as a damaged display screen, loose connection wires, or malfunctioning internal components, etc., and these failures will also cause the main display 50 to malfunction.

[0070] At this time, the processor 40 will output a corresponding alarm message according to the type of abnormality. To ensure the visibility and readability of the alarm message, the processor 40 controls the auxiliary display 60 to display the alarm message so that relevant personnel can clearly see the alarm content. By promptly outputting the alarm message and controlling the auxiliary display 60 to display the alarm content, the processor 40 can help relevant personnel quickly discover and handle the abnormalities of the ventilation device or the main display 50, and can improve the safety of device use. This function of the processor 40 can ensure that when the main display 50 fails, there is still an alternative display method available, thereby enhancing the overall reliability of the ventilation device.

[0071] In some embodiments, the processor 40 is further configured to control the auxiliary display 60 to display a corresponding alarm message when one or more sensors 20 monitor that the first data representing the patient's ventilation state and the respiratory circuit state exceeds its corresponding preset range.

[0072] For example, it may involve detecting that the patient's respiratory rate is too fast or too slow, the tidal volume is too high or too low, the pressure in the breathing circuit is too high or too low, the pressure of the gas source is too high or too low, and the minute ventilation volume is too high or too low. These emergency situations may directly pose a threat to the patient and need to be dealt with in a timely manner. Therefore, on the premise of displaying the alarm information on the conventional main display 50, it is very necessary to display the alarm information in a more prominent form through the auxiliary display 60, especially when the main display 50 has a display failure. By reasonably setting the alarm threshold, strengthening the monitoring of alarm information, and performing regular maintenance and inspections, etc., the safe operation of the ventilation equipment can be ensured, and the treatment effect and satisfaction of the patient can be improved.

[0073] In some embodiments, the display forms of the alarm information include at least two of text, image, animation, and pop-up window, and different display forms correspond to different alarm levels.

[0074] In practical applications, the above-mentioned situations that require alarms also have different levels of urgency for handling. Severe alarms usually correspond to the highest-level alarms and require immediate measures to be taken for handling. In this case, the system may simultaneously use multiple display forms such as text, image, animation, and pop-up window to emphasize the urgency of the alarm information. For example, the system may display red alarm text, flashing alarm icons, rotating indicators, and a popped-up alarm window.

[0075] General alarms usually correspond to lower-level alarms, but still require attention and handling. In this case, the system may use display forms such as text, image, or pop-up window to convey the alarm information. For example, the system may display yellow alarm text, corresponding alarm icons, and a popped-up alarm prompt box.

[0076] In practical applications, there are also some prompt messages that need the user's attention. Prompt messages usually correspond to non-emergency alarms or status changes and are used to remind relevant personnel of the operating status of the device. In this case, the system may use simple display forms such as only text or image to convey the prompt message. For example, the system may display gray prompt text or corresponding status icons.

[0077] Distinguishing different alarm levels through different display forms can help relevant personnel quickly identify and respond to alarm information. Combining multiple display forms such as text, image, animation, and pop-up window can more intuitively display the content of the alarm information and improve readability. A clear and intuitive alarm information display form can enhance the usage experience and work efficiency of medical staff, and also reduce the possibility of false alarms and missed alarms.

[0078] Next, a detailed description will be given of the selective display, under the control of the processor 40, of some of the ventilation parameters, vital sign parameters, and / or device operation parameters displayed on the main display 50 by the auxiliary display 60 in any of the above embodiments.

[0079] Figure 4 It is a schematic diagram of the interface of the auxiliary display provided by an embodiment of the present application. As Figure 4 shown, in this embodiment, the auxiliary display 60 includes at least one of a first display area 601 and a second display area 602.

[0080] In some embodiments, the processor 40 is further configured to respond to an operation of selecting a first form and determine the display form of the parameters to be displayed in the first display area 601. It can be understood that in the ventilation device, the processor 40 not only controls the core operation logic of the device but also is responsible for interacting with the user interface to meet various needs of the user. The processor 40 responds to the operation of selecting a first form and determines the display form of the parameters to be displayed in the first display area 601. In other words, the processor 40 can adjust the display mode of the parameters on the device interface according to the instructions or selections of the user. This flexibility enables the ventilation device to adapt to the needs and preferences of different users and also facilitates the operation and maintenance of the device.

[0081] In some embodiments, the first form includes at least one of a parameter bar graph, a waveform graph, and a numerical value.

[0082] The parameter bar graph is usually used to intuitively display the current state or change trend of a certain parameter. When displayed, the height or length of the bar graph can represent the size of the parameter, and the change in color can further indicate the state of the parameter.

[0083] In some embodiments, when the auxiliary display 60 displays in the form of a parameter bar graph, the parameter bar graph includes volume or pressure; the parameter unit of the parameter bar graph on the auxiliary display 60 is the same as the parameter unit of the corresponding parameter on the main display 50, and the display content of the parameter bar graph is also synchronously and real-time refreshed with the main display 50. The parameter unit of the parameter bar graph is the same as the parameter unit of the main display 50 to ensure the accuracy and consistency of information. For example, when displaying the pressure of the breathing circuit in the form of a bar graph, its unit can be Pascal, and when displaying the volume of the gas source in the form of a bar graph, its unit can be milliliter. The parameter unit of the parameter bar graph on the auxiliary display 60 is the same as the parameter unit of the corresponding parameter on the main display 50, which can avoid misunderstandings or confusions caused by inconsistent units. The parameter information of the parameter bar graph on the auxiliary display 60 and the main display 50 will be updated immediately to reflect the latest state. This synchronous refresh mechanism ensures that the user can obtain accurate information of the device in real time, so as to make timely and correct decisions.

[0084] A waveform graph is suitable for showing the variation of parameters over time. It can clearly display characteristics such as the fluctuations and periods of parameters, and is very useful for analyzing the dynamic behavior of parameters.

[0085] Numerical values are the most direct and accurate display method, which can accurately give the current value of the parameter, but may not be as intuitive as a bar graph or a waveform graph.

[0086] In practical applications, users may choose the most suitable display form according to the current working environment, task requirements or personal habits. For example, when quickly understanding the status of a certain parameter, users may choose an intuitive bar graph; while when in-depth analysis of the parameter change trend is needed, a waveform graph is more suitable.

[0087] In some embodiments, the processor 40 is further configured to control the first display area 601 to display text or an icon indicating that the ventilation device is in a standby state when the ventilation device is in the standby state. Specifically, when the ventilation device enters the standby mode, the processor 40 will detect this state change and trigger the corresponding display control logic, and display the first display area 601 of the auxiliary display 60 through instructions. The display method can be text or an icon, so that users can clearly understand that the device is not in the active working state but in the low-power standby state at a glance.

[0088] In some embodiments, the second display area 602 of the auxiliary display 60 is used to display the real-time pressure values of one or more gas sources, which can improve the monitoring efficiency and support multi-gas-source monitoring. In some embodiments, the auxiliary display 60 has an independent power supply. Therefore, whether the ventilation device is in the ventilation state or the standby state, the second display area 602 of the auxiliary display 60 can display the real-time pressure values of one or more gas sources, so as to monitor the usage of the gas source even in the standby state.

[0089] Figure 5 The structural schematic diagram of the ventilation device provided by another embodiment of the present application. As Figure 5 shown, in any of the above embodiments, the ventilation device at least includes a breathing circuit component 10, one or more sensors 20, a monitoring device 30, a processor 40, a main display 50, and an auxiliary display 60. In some embodiments, the ventilation device is further equipped with an auxiliary function device 70.

[0090] In some embodiments, the auxiliary function device 70 includes at least one of one or more evaporators, a breathing circuit heater, a breathing circuit humidifier, and an exhaust processor.

[0091] Under normal circumstances, the vaporizer is an essential auxiliary functional device 70 of the anesthesia machine. The vaporizer can effectively evaporate the liquid volatile anesthetic liquid into gas. The vaporizer can not only evaporate the anesthetic liquid, but also precisely adjust the concentration of the anesthetic vapor output, which is crucial for maintaining the appropriate anesthetic depth of the patient during the operation, ensuring the safety and effectiveness of anesthesia.

[0092] The main function of the breathing circuit heater is to maintain the temperature of the gas in the breathing circuit. During ventilation, if the gas temperature is too low, it may cause irritation to the patient and even affect the treatment effect. By heating the gas in the breathing circuit, it can be maintained within an appropriate range, thereby improving the patient's comfort and reducing the discomfort caused by too low gas temperature. In addition, for some treatments that require specific temperature conditions, the breathing circuit heater can also provide the necessary temperature support.

[0093] The main function of the breathing circuit humidifier is to increase the humidity of the gas in the breathing circuit. During ventilation, dry gas may cause irritation to the patient's respiratory tract, resulting in discomfort or injury. The humidifier adds an appropriate amount of moisture to the gas to keep it at a certain humidity, thereby reducing the irritation to the respiratory tract. This helps to protect the patient's respiratory mucosa and improve the effect of ventilation treatment and the patient's comfort. Especially during long-term ventilation treatment, the role of the humidifier is particularly important.

[0094] The main function of the exhaust gas processor in the ventilation device is to process and purify the discharged gas. For example, during anesthesia and ventilation, the gas exhaled by the patient and the waste gas that may be generated in the device need to be discharged safely and effectively. The exhaust gas processor can purify these gases, removing harmful substances such as anesthetic drug residues and carbon dioxide, to ensure that the discharged gas meets environmental protection and safety requirements. In addition, the exhaust gas processor can also prevent problems such as gas leakage and cross-infection, ensuring the safety of patients and medical staff.

[0095] Figure 6 This is a schematic diagram of the interface of the auxiliary display provided by another embodiment of the present application. As Figure 6 shown, in this embodiment, the auxiliary display 60 at least includes a first display area 601, a second display area 602, a third display area 603, and a fourth display area 604.

[0096] Based on the above embodiment, when the ventilation device has one or more vaporizers, under the control of the processor 40, the auxiliary display 60 displays the usage status of one or more vaporizers, as well as the capacity and remaining liquid volume of the vaporizer in the usage state, in the third display area 603.

[0097] When the ventilation device is equipped with respiratory circuit auxiliary devices such as a respiratory circuit heater, a respiratory circuit humidifier, and an exhaust gas processor, the processor 40 is further configured to control the auxiliary display 60 to display words or icons indicating that the respiratory circuit auxiliary device is not in use in the fourth display area 604 when the respiratory circuit auxiliary device is not in use or the ventilation device is not connected to a power source, such as WARMER ON, WARMER OFF; and / or, when the respiratory circuit auxiliary device is in use or the ventilation device is connected to a power source, control the fourth display area 604 of the auxiliary display 60 not to display any words or icons.

[0098] Figure 7 This is the interface of the auxiliary display of an anesthesia machine provided by an embodiment of the present application. As Figure 7 shown, the auxiliary display 60 at least includes a first display area 601, a second display area 602, a third display area 603, and a fourth display area 604. The first display area 601 displays the anesthesia machine volume in a bar graph, including the current value, the threshold range, and the parameter unit. The second display area 602 displays the pressures of three types of gas sources (oxygen, nitrogen, and air) in numerical values, including the pipeline pressure value and the gas source pressure value, and the parameter unit.

[0099] The third display area 603 displays the display status of the evaporator, including the volume and the remaining liquid volume, and the parameter unit.

[0100] The fourth display area 604 displays words indicating that the respiratory circuit heater is not in use.

[0101] Figure 8 This is a schematic diagram of the interface of the auxiliary display provided by another embodiment of the present application. Based on the original intention of equipping the auxiliary display 60, in order to capture key parameter information from the complex data of the main display 50. Therefore, as Figure 8 shown, in some embodiments, when the auxiliary function devices 70 are not in use, the display range of the second display area 602 is adaptively adjusted to cover the area with no content display. That is to say, when there is no content display in the third display area 603 and / or the fourth display area 604, the display range of the second display area 602 will expand to cover the third display area 603 and / or the fourth display area 604, so that the content displayed in the second display area 602 is more prominent, improving the readability of the auxiliary display 60.

[0102] In summary, the ventilation device provided by any of the above embodiments is based on an additional auxiliary display equipped on a conventional ventilation device. Through the control of a processor, it selectively displays some parameters that need special attention among the ventilation parameters, vital sign parameters, and / or device operation parameters displayed on the main display, and when a display failure occurs on the main display, it displays alarm information and important parameters. This not only improves data readability and system reliability, but also provides a basis for emergency treatment for medical staff, optimizes the operation experience, and enhances patient safety.
