Description

Technical Field

[0001] The present invention relates to the technical field of gas vibration, and particularly relates to a control method, device, intelligent device and computer-readable storage medium for a gas vibration device. Background Art

[0002] Respiratory diseases, such as chronic obstructive pulmonary disease, pneumonia, bronchiectasis and other pulmonary infectious diseases, are usually accompanied by the production of a large amount of airway secretions (sputum). If not cleared in time, it may lead to airway obstruction, ventilation limitation, and even serious complications such as hypoxemia and atelectasis. To improve the treatment efficiency, it is usually necessary to combine multiple treatment methods, including expiratory positive pressure support, gas vibration sputum drainage and nebulization inhalation.

[0003] In order to reduce the need for patients to switch between different devices, in recent years, some devices have tried to integrate these functions (expiratory positive pressure support, gas vibration sputum drainage and nebulization inhalation) into the same device to improve the convenience of treatment. However, in order to achieve flexible switching between different working modes such as expiratory positive pressure, vibration sputum drainage and nebulization treatment, existing multifunctional sputum drainage devices often require complex control algorithms to manage the air flow path to ensure smooth conversion between different modes. In addition, these devices also require additional microprocessors and storage units to run the control algorithms, increasing the R & D, production and maintenance costs of the devices. Summary of the Invention

[0025] The embodiments of the present application disclose a control method, device, intelligent device and computer-readable storage medium for a gas vibration device. By setting multiple control valves and combining user instructions, the air flow path can be flexibly controlled, realizing flexible switching among multiple functions of expiratory positive pressure, vibration sputum drainage and atomization therapy, avoiding the dependence on complex control algorithms and microprocessors, thereby simplifying the system structure and reducing the equipment cost and maintenance difficulty. The following will be described in detail respectively.

[0026] To better understand the embodiments of the present application, the related technologies will be described below.

[0027] Respiratory support and airway clearance are important measures to ensure the life safety of patients and improve the treatment effect. Especially in the fields of intensive care, anesthesia assistance, chronic obstructive pulmonary disease management, etc., patients often need to rely on positive pressure ventilation equipment or airway vibration devices to maintain smooth breathing and promote sputum excretion. However, in the prior art, most respiratory support and sputum drainage devices usually work independently, and manual switching of devices or dependence on additional connecting pipelines is required during use, resulting in complex device operation and poor patient experience.

[0028] Traditional expiratory positive pressure devices are mainly used to provide gas support at a certain pressure to improve the oxygenation state of patients and prevent alveolar collapse, while vibration sputum drainage devices help patients clear sputum in the respiratory tract by means of air flow vibration or mechanical vibration. Existing vibration sputum drainage devices usually rely on a single vibration mode and are difficult to be flexibly adjusted according to patient needs. At the same time, in a medical scenario, due to the dynamic changes in the patient's condition, it is often necessary to frequently switch device modes or adjust connection methods, increasing the operation complexity.

[0029] To solve the above technical problems, in the embodiments of the present application, the gas vibration device includes an air inlet interface, a first control valve, a second control valve, a third control valve, a gas vibration device, an atomization interface, an expiratory positive pressure interface, and a vibration sputum drainage interface. The air inlet interface is respectively connected to the air inlet port of the first control valve and the atomization interface. The first air outlet port and the second air outlet port of the first control valve are respectively connected to the air inlet port of the second control valve and the air inlet port of the third control valve. The first air outlet port of the second control valve and the first air outlet port of the third control valve are connected to the expiratory positive pressure interface. The second air outlet port of the second control valve and the second air outlet port of the third control valve are connected to the vibration sputum drainage interface through the gas vibration device. The control method includes: receiving a selection instruction from the user; controlling the opening and closing of the first control valve according to the selection instruction; receiving a working instruction from the user; controlling the opening and closing of the second control valve and the third control valve according to the working instruction. It can be seen that compared with frequently switching between multiple devices, by providing an air inlet interface, multiple control valves (the first control valve, the second control valve, and the third control valve), a gas vibration device, an atomization interface, an expiratory positive pressure interface, and a vibration sputum drainage interface, and adopting a multi-valve linkage structure, by controlling the opening and closing of different control valves, the automatic switching of the air flow path in multiple treatment modes such as expiratory positive pressure support, gas vibration sputum drainage, and atomization inhalation is realized, without relying on complex control algorithms and calculation logics, reducing the dependence on the microprocessor and the storage unit, thereby simplifying the system structure and reducing the equipment cost and maintenance difficulty.

[0030] To better understand the embodiments of the present application, the gas vibration device of the embodiments of the present application will be described first below.

[0031] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a gas vibration device disclosed in the embodiments of the present application. As Figure 1 shown, the gas vibration device may include an air inlet interface 10, a first control valve 20, a second control valve 30, a third control valve 40, a gas vibration device 50, an atomization interface 60, an expiratory positive pressure interface 70, and a vibration sputum drainage interface 80.

[0032] Among them, the air inlet interface 10 is used to connect to a gas source to provide gas input for the device. The air inlet interface 10 is respectively connected to the air inlet port of the first control valve 20 and the atomization interface 60. Preferably, an atomization cup is provided on the atomization interface 60 for loading atomized liquid medicine. The gas directly enters the atomization cup through the air inlet interface, pushing the liquid medicine to form an aerosol for the patient to inhale for treatment.

[0033] The first control valve 20 is provided with at least two air outlet ports, namely a first air outlet port and a second air outlet port, for distributing the input gas to different air flow paths as required. Among them, the first air outlet port and the second air outlet port of the first control valve 20 are respectively connected to the air inlet ports of the second control valve 30 and the third control valve 40.

[0034] The second control valve 30 and the third control valve 40 are respectively used for switching the air flow between the positive expiratory pressure mode and the vibration sputum drainage mode. Specifically, the first air outlet ports of the second control valve 30 and the third control valve 40 are commonly connected to the positive expiratory pressure interface 70 for outputting gas to the patient's breathing mask or airway interface to provide positive pressure support. The second air outlet ports of the second control valve 30 and the third control valve 40 are connected to the vibration sputum drainage interface 80 through the gas vibration device 50, and the gas is sent into the patient's airway after vibration treatment to promote sputum loosening and discharge.

[0035] In this embodiment, the first control valve, the second control valve and the third control valve can be three-way solenoid valves, mechanical rotary valves or other controllable fluid control elements with multiple air outlet channels. By controlling the on-off states of the control valves, rapid switching of the air flow path can be achieved, so as to flexibly support the conversion of different treatment modes.

[0036] In some embodiments, the above control valves can be controlled according to the working instructions input by the user, and the instructions can include an automatic operation mode and a manual selection mode. In the automatic mode, the system controls each control valve to switch in sequence according to a preset program to realize the automatic execution of the treatment process; in the manual mode, the user can select the treatment method according to actual needs and control the states of the relevant valves to improve the operation flexibility of the device.

[0037] It can be understood that based on the clinical treatment process, it is usually necessary to first perform positive expiratory pressure ventilation to expand the airway and open the passage, and then perform vibration sputum drainage to promote sputum loosening and discharge. The two are often continuous in time and can share the same airway output interface in space without physical switching, thus simplifying the structure, reducing the number of interfaces, and reducing the volume and cost of the device. Therefore, the positive expiratory pressure interface 70 and the vibration sputum drainage interface 80 can be the same interface, that is, a common interface structure, for outputting the air flow in different treatment modes. In this common interface structure, different treatment air flows are switched by the system according to the state of the working instructions and the valve combination: In addition, the common interface can also cooperate with the automatic control logic of the treatment sequence, such as setting the "ventilation pretreatment + vibration sputum drainage" mode, to improve the treatment continuity and efficiency.

[0038] In some embodiments, the gas vibration device may further include a detection interface and a first pressure sensor. The detection interface is disposed in a branch gas path connected to the breathing accessory (such as communicating with the patient breathing tube or the handle circuit), and the first pressure sensor is disposed on the gas path connected to the detection interface.

[0039] The detection interface can receive the gas flowing back from the handle or the face mask and perform real-time monitoring through the first pressure sensor. If the first pressure sensor can continuously detect minute air pressure changes, it is determined that the connection of the detection interface is normal. If the pressure value detected by the first pressure sensor is 0, it is determined that the interface has fallen off. At this time, an audible and visual alarm can be triggered or the treatment operation can be paused, thereby realizing the anti-drop detection function.

[0040] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of a control method for a gas vibration device disclosed in an embodiment of the present application. As Figure 2 shown, the control method of the gas vibration device may include the following steps:

[0041] S201. Receive a selection instruction from the user.

[0042] In some embodiments, the device receives the selection instruction input by the user through a user interface (such as a button panel, a touch screen, a knob, or a remote control module). The selection instruction is used to determine the current operation mode of the device. The operation mode may include an automatic operation mode and a manual operation mode. Specifically:

[0043] In the automatic operation mode, the device can automatically perform corresponding air flow switching and output according to a preset program or treatment process, for example, performing expiratory positive pressure, vibration sputum drainage, and atomization treatment in sequence according to a set time period

[0044] In the manual operation mode, the device can allow the user to independently select the current required treatment function at any time point and allow the user to adjust the treatment plan according to their own needs immediately.

[0045] S202. Control the opening and closing of the first control valve according to the selection instruction.

[0046] In some embodiments, the selection instruction may include automatic operation and manual operation. Step S202 can determine the opening and closing state of the first control valve according to the operation mode determined in step S201. As the main gas path distribution node, the opening and closing state of the first control valve determines whether to divert the gas to the subsequent air outlet interfaces (expiratory positive pressure interface and vibration sputum drainage interface). Specifically:

[0047] In the automatic operation mode, when it is necessary to perform the expiratory positive pressure or vibration sputum drainage function, the first air outlet port of the first control valve is controlled to close, and the second air outlet port of the first control valve is controlled to open. When only the atomization function is to be performed or the main air path does not need to supply air, the first air outlet port and the second air outlet port of the first control valve remain closed to save the air source and prevent incorrect connection.

[0048] S203. Receive a work instruction from the user.

[0049] In some embodiments, the device may further receive a specific work instruction for determining which one or more treatment methods are to be performed currently. The work instruction may be manually input by the user or automatically generated by the system according to a preset logic in the automatic mode. Specifically:

[0050] Expiratory positive pressure: It is used to assist the patient in maintaining the airway patency and improving alveolar ventilation.

[0051] Vibration sputum drainage: It stimulates the airway through gas vibration to assist in loosening and discharging sputum.

[0052] Atomization: The liquid medicine is atomized and then delivered to the respiratory tract to play roles such as anti-inflammatory and bronchodilation.

[0053] S204. Control the opening and closing of the second control valve and the third control valve according to the work instruction.

[0054] In some embodiments, the work instruction may include expiratory positive pressure and vibration sputum drainage. Step S204 may perform targeted control on the second control valve and the third control valve according to the work instruction received in step S203.

[0055] These two groups of control valves respectively correspond to two-way function outputs, and the specific logic is as follows:

[0056] In the case where the selection instruction is automatic operation and the work instruction is expiratory positive pressure, control the first air outlet port of the first control valve and the second air outlet port of the third control valve to close, and control the first air outlet port of the third control valve to open.

[0057] In the embodiments of the present application, controlling the first air outlet port of the first control valve to close can prevent the gas from flowing to the second control valve. Controlling the second air outlet port of the third control valve to close can avoid the gas from entering the gas vibration device. Controlling the first air outlet port of the third control valve to open can directly deliver the gas to the expiratory positive pressure interface to provide continuous and stable positive pressure ventilation.

[0058] In the case where the selection instruction is automatic operation and the work instruction is vibration sputum drainage, control the first air outlet port of the first control valve and the first air outlet port of the third control valve to close, and control the second air outlet port of the third control valve to open.

[0059] In the embodiments of the present application, closing the first air outlet port of the first control valve can prevent gas from being diverted to the second control valve path. Closing the first air outlet port of the third control valve can prevent gas from entering the positive pressure output interface by mistake. Opening the second air outlet port of the third control valve can enable gas to be output to the vibration sputum drainage interface via the gas vibration device.

[0060] When the selection instruction is manual operation and the working instruction is expiratory positive pressure, close the second air outlet port of the first control valve and the second air outlet port of the second control valve, and open the first air outlet port of the second control valve.

[0061] In the embodiments of the present application, closing the second air outlet port of the first control valve can prevent gas from flowing to the third control valve. Closing the second air outlet port of the second control valve can prevent gas from entering the vibration path. Opening the first air outlet port of the second control valve can enable gas to be transported to the expiratory positive pressure interface through the second control valve.

[0062] When the selection instruction is manual operation and the working instruction is vibration sputum drainage, close the second air outlet port of the first control valve and the first air outlet port of the second control valve, and open the second air outlet port of the second control valve.

[0063] In the embodiments of the present application, closing the second air outlet port of the first control valve can cut off the gas flow to the third control valve. Closing the first air outlet port of the second control valve can prevent gas from entering the positive pressure path. Opening the second air outlet port of the second control valve can enable gas to flow to the vibration sputum drainage interface via the gas vibration device to complete sputum drainage treatment.

[0064] In some embodiments, the working instruction may further include atomization. When the working instruction is atomization, close the air inlet of the first control valve; and / or close the first air outlet port and the second air outlet port of the first control valve.

[0065] To ensure that gas can be directly supplied from the air inlet interface to the atomization interface and prevent ventilation in irrelevant paths, the above control method may further include the following steps:

[0066] Close the air inlet port of the first control valve to block gas from entering the main gas distribution path controlled by the first control valve and prevent gas from being diverted to the second control valve and the third control valve. And / or,

[0067] Close the first air outlet port and the second air outlet port of the first control valve to further ensure that the downstream treatment channels (such as expiratory positive pressure and vibration sputum drainage) will not be wrongly enabled.

[0068] In the embodiments of the present application, the gas source can be directly transported to the atomization interface only through the air inlet interface, driving the liquid medicine in the atomization cup to form an atomized aerosol, realizing an independent atomization treatment process, avoiding conflicts with other treatment modes, and improving the pertinence and safety of treatment.

[0069] In some embodiments, when the selection instruction is automatic operation and the working instruction is atomization, the first air outlet port of the first control valve and the first and second air outlet ports of the third control valve are controlled to be closed.

[0070] In the embodiments of the present application, controlling the first air outlet port of the first control valve to be closed can prevent gas from entering the second control valve, thereby avoiding accidental activation of the positive end-expiratory pressure path. At the same time, controlling the first and second air outlet ports of the third control valve to be closed ensures that gas does not enter the positive pressure output channel or the vibration output channel connected to the third control valve. Through the above settings, in the automatic atomization operation, all air paths not related to atomization treatment are cut off, and only the direct path from the air inlet interface to the atomization interface is retained, ensuring the stability of the air flow and the atomization efficiency of the liquid medicine, and avoiding interference between different treatment modes.

[0071] In some embodiments, when the selection instruction is manual operation and the working instruction is atomization, the second air outlet port of the first control valve and the first and second air outlet ports of the second control valve are controlled to be closed.

[0072] In the embodiments of the present application, controlling the second air outlet port of the first control valve to be closed can prevent gas from flowing to the third control valve, thereby avoiding triggering the positive pressure or vibration path of the third control valve. At the same time, controlling the first and second air outlet ports of the second control valve to be closed to block the possible path output from the second control valve to the positive end-expiratory pressure interface or the gas vibration device. Through the above settings, during the manual operation process, other treatment channels will not be accidentally activated when the user triggers the atomization mode, and the exclusivity and execution safety of the atomization treatment path can be realized.

[0073] In actual treatment, it is often necessary to combine aerosol inhalation with positive expiratory pressure or sputum drainage functions to improve the deposition efficiency and distribution uniformity of drugs in the airway. Therefore, in the embodiments of the present application, the aerosol function is always in an available state in terms of structure, that is, gas can directly flow from the air inlet interface to the aerosol interface and drive the aerosolization process. However, to avoid air path interference or drug waste during treatments such as positive expiratory pressure or vibratory sputum drainage, the system can prioritize ensuring the independence and stability of other treatment paths by closing the relevant outlet ports of the first control valve and the subsequent control valves in the control logic. Only when the user separately selects "aerosol" as the operation instruction in the automatic or manual mode, the system will actively close all air path channels related to positive expiratory pressure and vibratory sputum drainage (such as all outlet ports of the second control valve and the third control valve) to ensure the purity and path exclusivity of the aerosol airflow.

[0074] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of another gas vibration device disclosed in the embodiments of the present application. As Figure 3 shown, the gas vibration device may further include an air path switch 90. One end of the air path switch 90 is connected to the air inlet interface 10, and the other end of the air path switch 90 is respectively connected to the air inlet port of the first control valve 20 and the aerosol interface 60.

[0075] The control method may further include: receiving a switch instruction from the user and controlling the opening and closing of the air path switch according to the switch instruction.

[0076] In some embodiments, the user can input the switch instruction through the operation interface, or the device control system can automatically generate the instruction according to the program logic during the automatic operation process. The switch instruction is used to determine whether the gas source enters the main control path of the device. When the "open" instruction is received, the air path switch can be driven to open, enabling the gas to enter the device from the air inlet interface and flow to the first control valve and / or the aerosol interface; when the "close" instruction is received, the air path switch disconnects the air inlet path, thereby cutting off the gas source supply to all subsequent treatment modules for gas source shielding in the standby state, treatment pause state, or abnormal protection state of the device.

[0077] Please refer to Figure 4 , Figure 4 which is a schematic structural diagram of yet another gas vibration device disclosed in the embodiments of the present application. As Figure 4 shown, the gas vibration device may further include a solenoid valve 100 and a pressure detection device 110. One end of the solenoid valve 100 is connected to the air inlet interface 10, the other end of the solenoid valve 100 is respectively connected to the air inlet port of the first control valve 20 and the aerosol interface 60, and the pressure detection device 110 is connected to the solenoid valve 100.

[0078] The control method may further include: detecting the gas pressure value after flowing through the solenoid valve by a pressure detection device, and controlling the solenoid valve to disconnect the gas path when the gas pressure value exceeds a preset pressure value.

[0079] In some embodiments, on the basis of the original intake control structure, the gas vibration device is further provided with a solenoid valve 100 and a pressure detection device 110 to enhance the safety and controllability of the gas path.

[0080] Specifically, the solenoid valve 100 is arranged between the intake interface 10 and the downstream gas path for controlling whether gas enters the subsequent interface. One end of the solenoid valve 100 is connected to the intake interface 10 for receiving an external gas source, and the other end is provided with two branches, which are respectively connected to the intake port of the first control valve 20 and the atomization interface 60, so as to realize unified gas supply control for the main treatment path and the atomization path.

[0081] The pressure detection device 110 is used to monitor the gas pressure at the output end of the solenoid valve 100 in real time. Its installation method can be installed on the outlet main pipe of the solenoid valve 100; or respectively connected to the branch paths leading to the first control valve 20 and the atomization interface 60.

[0082] In the embodiments of the present application, the pressure data detected by the pressure detection device can be fed back in real time for judging the current gas path state. Further, the feedback value of the pressure detection device can be collected regularly or in real time to evaluate whether the gas supply is in a normal state. When it is detected that the gas pressure downstream of the solenoid valve exceeds the set safety threshold (such as overpressure risk), it indicates that there may be abnormal situations such as downstream blockage, misoperation, equipment failure, etc. To prevent the gas from continuing to be transported and causing danger, the solenoid valve can be closed to cut off the main intake path and ensure the safety of the equipment and the patient.

[0083] It can be understood that the preset pressure value can be dynamically adjusted according to different treatment modes. For example, a lower pressure is allowed during atomization, and a slightly higher pressure is allowed for positive end-expiratory pressure. The preset pressure value can be combined with a time judgment mechanism, such as triggering a protection action only when the threshold is exceeded continuously for a certain time, to avoid false alarms caused by instantaneous pressure fluctuations. On this basis, after triggering the overpressure protection, an alarm mode or a locked state can be entered to prompt the user to check the system status.

[0084] Please refer to Figure 5 , Figure 5 FIG. is a schematic structural diagram of another gas vibration device disclosed in the embodiments of the present application. As Figure 5 shown, on the basis of the above embodiments, the gas vibration device may further include a gas path pressure regulating device 120. The intake port of the gas path pressure regulating device 120 is respectively connected to the first outlet port of the second control valve 30 and the first outlet port of the third control valve 40, and the outlet port of the gas path pressure regulating device 120 is connected to the positive end-expiratory pressure interface 70.

[0085] The control method may further include: receiving a pressure adjustment instruction input by a user, and adjusting the gas pressure according to the pressure adjustment instruction through a gas path pressure adjustment device.

[0086] In some embodiments, the gas path pressure adjustment device 120 is provided with an air inlet port and an air outlet port. Among them, the air inlet port is respectively connected to the first air outlet port of the second control valve 30 and the first air outlet port of the third control valve 40, and is used to receive the input of expiratory positive pressure gas from two paths; the air outlet port is connected to the expiratory positive pressure interface 70, and is used to stably transport the adjusted gas pressure to the patient's breathing mask or artificial airway.

[0087] The gas path pressure adjustment device can be in the form of a mechanical pressure regulating valve, an electric pressure regulating valve or a proportional valve with electronic closed-loop control, etc. The specific selection can be determined according to the actual control accuracy and response speed requirements.

[0088] In the embodiments of the present application, the user can input the desired positive pressure intensity through the operation interface, or the preset treatment program automatically generates the corresponding pressure parameters at different stages. This instruction is used as the target value setting input of the pressure adjustment device. Further, according to the received target pressure value, the gas path pressure adjustment device can be driven to dynamically adjust the gas pressure to ensure that the air flow pressure output to the expiratory positive pressure interface is within the set range. The above adjustment process can be continuously adjustable (proportional control) or stepwise adjustment (multi-gear switching), and can form a closed-loop control in combination with a pressure sensor to achieve accurate and stable pressure output.

[0089] In some embodiments, the gas vibration device may further include a flow rate adjustment device 150.

[0090] The air inlet port of the flow rate adjustment device 150 is connected to the air outlet port of the gas path pressure adjustment device 120, and the air outlet port of the flow rate adjustment device 150 is connected to the expiratory positive pressure interface 70. The flow rate adjustment device 150 can adjust the gas flow rate output to the patient, so as to control the air flow intensity entering the respiratory positive pressure interface and avoid discomfort or potential airway damage caused by excessive flow rate.

[0091] The flow rate adjustment device 150 can be a manual knob type structure, and the user can manually adjust the opening degree of the gas path by rotating the knob to control the gas flow rate; it can also be an electronically controlled proportional valve, which can automatically adjust the flow rate according to the adjustment instruction sent by the control system.

[0092] As Figure 5 shown, the gas vibration device may further include a flow limiter 130. The air inlet port of the flow limiter 130 is connected to the air inlet port of the first control valve 20, and the air outlet port of the flow limiter 130 is connected to the atomization interface 60.

[0093] The flow limiter 130 is provided with an air inlet port and an air outlet port. Its air inlet port is connected to the air inlet port of the first control valve 20, and its air outlet port is connected to the atomization interface 60. Through this connection structure, the flow limiter 130 can limit and adjust the gas flow rate entering the atomization device from the gas source via the first control valve.

[0094] In the embodiment of the present application, the atomization function is a default open direct passage (i.e., the air inlet interface can be directly connected to the atomization interface). If the flow limiter is not set, it may cause the atomized particles to be too thick due to fluctuations in the gas source pressure or flow rate, affecting the drug deposition effect; the atomization speed is too fast, resulting in too fast consumption of the liquid medicine or insufficient inhalation of the drug; the air flow is too strong, irritating the patient, especially enhancing the discomfort of children or the elderly. Therefore, by setting the flow limiter in the present application, it can ensure that the gas entering the atomization cup maintains a constant flow rate, which helps to form a uniform and delicate aerosol and improve the drug absorption efficiency; it can avoid the gas source fluctuations caused by the switching operations of other modules (such as vibration sputum drainage or positive expiratory pressure) from being conducted to the atomization device; it can play a current-limiting protection role under high pressure to prevent damage to the atomization components or generate too strong an air flow to cause irritation to the patient.

[0095] As Figure 5 shown, the gas vibration device may further include a vibration frequency adjustment device 140. The vibration frequency adjustment device 140 can be arranged between the gas vibration device 50 and the vibration sputum drainage interface 80 for controlling the frequency output of the vibration air flow. It is used to adjust the vibration frequency of the gas vibration device to achieve the adaptation of different sputum drainage modes and improve the sputum drainage efficiency and the individualized level of treatment.

[0096] The control method may further include: receiving a vibration frequency selection instruction input by the user. The instruction may include a high-frequency instruction and a low-frequency instruction. Further, the gas output state can be adjusted according to the vibration frequency selection instruction, so that the pulsed gas flow generated by the gas vibration device is frequency-adjusted before being output to the vibration sputum drainage interface. Optionally, the optimal frequency can be automatically matched according to the preset parameters of the patient or the automatic detection results (such as age, lung compliance, etc.).

[0097] In some embodiments, the gas vibration device may further include a display module for real-time displaying the current operating parameters, operation status, and system prompt information of the device to the user.

[0098] The display module can be a digital tube display screen for displaying the core treatment parameters (such as air pressure, time, frequency, etc.) in digital form, with a fast response speed and low energy consumption, suitable for basic models of devices; it can also be a liquid crystal display screen, which can realize the display of multiple lines of text, icons, animations, etc., support the state prompt with both pictures and texts, and is suitable for displaying complex information (such as mode, alarm, network status, etc.).

[0099] In some embodiments, the gas vibration device may further include a communication module for implementing data communication, remote control, or status synchronization between the device and an external terminal. The communication module may be integrated into the main control board of the device or provided as an independent module, and interact with components such as the control system and the display module.

[0100] The communication module may be a Wi-Fi module to enable the device to connect to a local network, facilitating remote control, parameter setting, and operation status monitoring through a mobile phone App, a hospital information system, etc. It may also be a Bluetooth module for establishing a short-distance communication connection with a mobile terminal (such as a smart phone or a tablet computer), supporting local wireless control or data synchronization.

[0101] Please refer to Figure 6 , Figure 6 which is a schematic structural diagram of another gas vibration device disclosed in the embodiments of the present application. As Figure 6 shown, when the expiratory positive pressure interface and the vibration sputum drainage interface share the interface 170, the gas vibration device may further include a gas path confluence device 160. The intake ports of the gas path confluence device 160 are respectively connected to the outlet port of the flow rate regulating device 150 and the outlet port of the vibration frequency regulating device 140, and the outlet port of the gas path confluence device 160 is connected to the shared interface 170.

[0102] The gas path confluence device 160 can merge the gases from different control channels (the expiratory positive pressure path and the vibration sputum drainage path) and uniformly output them to the shared interface 170, thereby realizing the sequential output of the two treatment functions in time and the co-port output in structure, improving the simplicity of the system and the convenience of operation.

[0103] In some embodiments, the gas vibration device may further include a second pressure sensor and a gas path end control device. The intake ports of the gas path end control device are respectively connected to the outlet port of the gas path confluence device 160 and the second pressure sensor.

[0104] When the second pressure sensor detects that the output gas pressure exceeds the set upper threshold, it controls the gas path end control device to perform operations such as closing, current limiting, or disconnecting, thereby realizing overpressure response protection and preventing abnormal gas from entering the patient's airway.

[0105] Please refer to Figure 7 , Figure 7 which is an external view schematic diagram of a gas vibration device disclosed in the embodiments of the present application. As Figure 7 shown, the device consists of a control panel area, a support housing, and functional interfaces.

[0108] The upper knob is used to control the working frequencies of atomization and vibration sputum drainage and the selection and switching of expiratory positive pressure, and the lower knob is used to adjust the output flow rate (intensity) of respiratory positive pressure.

[0109] On the right side of the panel is the automatic control area, which adopts a button layout and includes function selection keys such as atomization, vibration sputum drainage, respiratory positive pressure, and flow rate adjustment;
