Description

[0001] This application is a divisional application of the parent application with application number "2021102723575", application date "2021.03.12", and invention title "Respiratory Control Component and Ventilation Therapy Device". Technical Field

[0002] This invention relates to the field of medical device technology, and in particular to a respiratory control component and a ventilation therapy device. Background Technology

[0003] Ventilation therapy devices typically include an airflow generator, an air delivery tube, and a user interface device. The user interface device delivers positive pressure airflow generated by the airflow generator into the user's airway to achieve positive pressure ventilation therapy. During use, if the user swallows or yawns, their Eustachian tube may open. Because the ventilation therapy device continues to deliver positive pressure airflow to the user at this time, and the Eustachian tube cannot close on its own under positive pressure, there is a potential risk of ear perforation and other problems, and in severe cases, hearing loss. Therefore, existing ventilation therapy devices pose certain safety hazards. Summary of the Invention

[0004] The technical problem to be solved by the embodiments of the present invention is to provide a breathing control component and a ventilation therapy device that can stop supplying airflow to the user when the user's Eustachian tube is detected to be open, and resume supplying airflow when the user's Eustachian tube is detected to be closed, so as to eliminate the health risks when the user uses the breathing control component.

[0005] To address the aforementioned problems, an embodiment of the first aspect of the present invention provides a breathing control component, comprising:

[0006] The module consists of a data acquisition module, a control module, and a gas delivery module.

[0007] The acquisition module is communicatively connected to the control module. The acquisition module is used to acquire the gas parameters of the user's Eustachian tube and send the gas parameters to the control module.

[0008] The control module is communicatively connected to the gas delivery module. The control module is used to determine the opening and closing state of the Eustachian tube according to the gas parameters, and to configure the gas delivery state of the gas delivery module according to the opening and closing state.

[0009] Optionally, the acquisition module includes a barometric pressure detector and an in-ear structure for housing the barometric pressure detector, wherein the gas parameter is the air pressure in the external auditory canal connected to the Eustachian tube, and the barometric pressure detector is used to acquire the air pressure in the external auditory canal.

[0010] The control module is also configured to: determine that the Eustachian tube is open when the external auditory canal pressure is detected to be greater than the initial pressure, and control the air delivery module to stop delivering air; and determine that the Eustachian tube is closed when the external auditory canal pressure is detected to drop to less than or equal to the initial pressure, and control the air delivery module to continue delivering air.

[0011] Optionally, the acquisition module further includes an ear hook structure connected to the ear in-ear structure, the ear hook structure being used to hang on the user's auricle.

[0012] Optionally, the acquisition module includes a sound wave detector and a patch structure for housing the sound wave detector, wherein the sound wave detector is used to acquire sound wave information of respiratory airflow.

[0013] The control module is configured to: determine that the Eustachian tube is open and control the air delivery module to stop supplying air when the matching degree between the waveform of the sound wave information and the preset waveform is less than a preset matching threshold; and determine that the Eustachian tube is closed and control the air delivery module to continue supplying air when the matching degree is greater than or equal to the preset matching threshold.

[0014] Optionally, the breathing control component further includes:

[0015] The prompting module is communicatively connected to the control module, and is used to send a prompting message when the control module determines that the Eustachian tube is open.

[0016] Optionally, the gas delivery module includes a gas flow generator and a controlled device that are connected in communication, and a gas delivery pipe connected to the gas flow generator. The controlled device is connected in communication with the control module and receives control parameters from the control module to control the gas flow generator to deliver gas or stop delivering gas through the gas delivery pipe according to the control parameters.

[0017] Optionally, the controlled device is a switch controller for the airflow generator, one end of the air supply pipe is connected to the airflow generator, and the other end of the air supply pipe is used to supply air to the user. When the Eustachian tube is open, the control parameters are used to control the switch controller to turn off the airflow generator. When the Eustachian tube is closed, the control parameters are used to control the switch controller to turn on the airflow generator.

[0018] Optionally, the controlled device is a control valve, which is used to control the opening or closing of the air supply tube. When the Eustachian tube is open, the control parameter is used to control the closing of the control valve. When the Eustachian tube is closed, the control parameter is used to control the opening of the control valve.

[0019] A second aspect of the present invention provides a ventilation therapy device, comprising:

[0020] Breathing mask;

[0021] The breathing control assembly as described in any embodiment of the first aspect of the present invention includes an air supply tube and an airflow generator, one end of the air supply tube being connected to the breathing mask and the other end of the air supply tube being connected to the airflow generator.

[0022] Optionally, the breathing control assembly includes a controlled device, wherein if the controlled device is a control valve, the control valve is disposed on the air supply tube, and / or disposed at the connection between the air supply tube and the breathing mask, and / or disposed at the connection between the air supply tube and the airflow generator.

[0023] The respiratory control component defined in this embodiment of the invention includes a data acquisition module, a control module, and a gas delivery module connected in sequence for communication. This forms a servo control system that controls the gas delivery state of the gas delivery module based on the gas parameters of the user's Eustachian tube collected by the data acquisition module. Specifically, the data acquisition module transmits the collected gas parameters of the user's Eustachian tube to the control module. The control module can determine whether the Eustachian tube is open or closed based on changes in the gas parameters. If the Eustachian tube is open, the control module generates a control command to stop the gas delivery module from delivering gas, thereby eliminating the positive pressure in the Eustachian tube and causing it to close automatically. If the Eustachian tube is closed, the control module generates a control command to continue delivering gas, so that the respiratory control component continuously delivers gas to the user for treatment.

[0024] By incorporating a respiratory control component with a data acquisition module, the component enhances operational reliability and improves treatment outcomes for users with independent abilities. For users without independent abilities, the component prevents the risk of ear perforation, hearing loss, or other problems during treatment, thereby improving operational safety.

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] In this invention, unless otherwise stated, directional terms such as "top" and "bottom" generally refer to the orientation shown in the accompanying drawings. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0038] like Figure 1 The image shows a ventilation therapy device in the related art, including an interface device 102 covering the user's mouth and nose, an airflow generator 106, and an air supply tube 104 connecting the interface device 102 and the airflow generator 106. During treatment, the interface device 102 covers the user's mouth and nose and / or mouth. The airflow generated by the airflow generator 106 enters the user's nasal cavity and / or oral cavity through the air supply tube 104 and the interface device 102. When the user swallows or yawns, their Eustachian tube (also known as the Eustachian tube, an important passage connecting the tympanic cavity and nasopharynx, which only opens during swallowing or yawning to balance the air pressure in the middle and outer ear, facilitating the normal vibration of the tympanic membrane) opens. Because the ventilation therapy device still delivers positive pressure airflow to the user at this time, the Eustachian tube cannot close on its own under positive pressure.

[0039] For users with eustachian tube opening, those capable of self-management need to interrupt treatment and resume it only after the eustachian tube closes, a cumbersome process that affects treatment effectiveness. For users without self-management capabilities, when the eustachian tube is open, treatment cannot be interrupted in time, and the tympanic membrane connected to the eustachian tube will be continuously subjected to the ventilator's airflow, posing a potential risk of ear perforation and, in severe cases, hearing loss. Therefore, the ventilation therapy equipment in this technology presents certain safety hazards.

[0040] Figure 2 This diagram illustrates the Eustachian tube in its closed state. The Eustachian tube 202 is a trachea in the human body that connects the tympanic cavity to the nasopharynx behind the nasal cavity. It is approximately 3.5cm to 4.0cm long. The first third of the Eustachian tube 202 near the tympanic cavity is composed of bone, while the second third near the nasopharynx is composed of cartilage. The tympanic orifice of the Eustachian tube 202 is located on the anterior wall of the tympanic cavity, and the opening connecting to the nasopharynx is the pharyngeal orifice. The tympanic orifice remains unobstructed at all times, while the pharyngeal orifice functions like a one-way valve. Figure 2 As shown, the pharyngeal opening is normally closed, allowing only liquid or gas from the middle ear to overflow, while preventing nasopharyngeal secretions and bacteria from entering the tympanic cavity. This keeps the tympanic membrane 206 and round window membrane in the optimal vibration position for normal hearing. Only when opening the mouth, singing, chewing, yawning, or swallowing does the pharyngeal muscle contract, causing the pharyngeal opening of the Eustachian tube 202 to open. Figure 3 As shown, outside air can then enter the tympanic cavity, thus balancing the pressure inside and outside the tympanic cavity and ensuring normal sound transmission in the middle ear.

[0041] During treatment, when the user swallows or yawns, the pharyngeal opening of the Eustachian tube 202 opens, and airflow from the breathing control component enters the middle ear canal 204 through the Eustachian tube 202. The air pressure in the middle ear is greater than that in the outer ear, and the tympanic membrane 206 bulges out into the outer ear canal 208. At this time, the tympanic membrane 206 cannot vibrate normally, affecting the user's hearing. If the air pressure in the middle ear continues to increase to a level greater than the tympanic membrane 206 can withstand, the tympanic membrane 206 will rupture, causing an ear perforation, which will result in permanent hearing loss for the user.

[0042] Based on the existing safety hazards of the breathing control component 30 during use, and referring to... Figure 4 The diagram shows a structural diagram of a breathing control component 30 of the present invention. The breathing control component 30 includes: a data acquisition module 302, a control module 304, and a gas delivery module 306.

[0043] The acquisition module 302 is communicatively connected to the control module 304. The acquisition module 302 is used to acquire the gas parameters of the Eustachian tube 202 and send the gas parameters to the control module 304.

[0044] Specifically, since the Eustachian tube 202 is located inside the human body, the acquisition module 302 acquires the gas parameters of the Eustachian tube 202. Specifically, it acquires the gas parameters transmitted through the Eustachian tube 202, or the gas parameters in the external auditory canal 208 which is separated from the Eustachian tube 202 by the tympanic membrane. The gas parameters can specifically be air pressure parameters, respiratory frequency parameters of the respiratory gas in the Eustachian tube 202, or respiratory sound wave parameters of the respiratory gas, etc. The acquisition module 302 is specifically a sensor that acquires the above parameters.

[0045] The control module 304 is communicatively connected to the gas delivery module 306. The control module 304 is used to determine the opening and closing state of the Eustachian tube 202 according to the gas parameters, and to configure the gas delivery state of the gas delivery module 306 according to the opening and closing state.

[0046] The control module 304 is specifically a control chip. The control module 304 determines the opening and closing state of the Eustachian tube 202 based on the acquired gas parameters. Specifically, it can determine whether the change in the detected gas parameters exceeds a preset range, and determine whether to generate control parameters to adjust the gas delivery module 306 based on the detection results.

[0047] The gas delivery module 306 is used to deliver gas to the user to assist the user's breathing. The gas delivery module 306 is communicatively connected to the control module 304 so that its operation can be controlled by the control module 304. The gas delivery module 306 may include an airflow generator 3062 and a gas delivery pipe 3064 that are interconnected. Therefore, the gas delivery status can be configured according to the control parameters to control the opening and closing status of the airflow generator 3062 and the opening and closing status of the gas delivery pipe 3064 to realize gas delivery or stop gas delivery.

[0048] In addition, the data acquisition module 302 and the control module 304 can be connected by wired or wireless communication, and the control module 304 and the gas delivery module 306 can be connected by wired or wireless communication.

[0049] In this embodiment, the respiratory control component 30 is a servo control system that controls the gas delivery state of the gas delivery module 306 based on the gas parameters of the user's Eustachian tube 202 collected by the acquisition module 302. Specifically, the acquisition module 302 transmits the collected gas parameters of the user's Eustachian tube 202 to the control module 304. The control module 304 can determine whether the Eustachian tube 202 is in an open or closed state based on whether the gas parameters change. If the Eustachian tube 202 is in an open state, the control module 304 generates a control command to stop the gas delivery module 306 from delivering gas to eliminate the positive pressure in the Eustachian tube 202, thereby causing the Eustachian tube 202 to close automatically. If the Eustachian tube 202 is in a closed state, the control module 304 generates a control command to continue the gas delivery module 306 from delivering gas, so that the respiratory control component 30 continuously delivers gas to the user for treatment.

[0050] By setting up a breathing control component 30 with a data acquisition module 302, when treating a user, the breathing control component 30 can improve the reliability of operation for users with independent abilities, thereby improving the treatment effect. For users without independent abilities, the breathing control component 30 can prevent the user from experiencing the risk of "ear perforation" or hearing loss during treatment, thereby improving the safety of operation.

[0051] like Figure 6 As shown, in some embodiments, the acquisition module 302 includes a pressure detector 302A and an in-ear structure for accommodating the pressure detector 302A. The gas parameter is the air pressure of the external auditory canal 208 connected to the Eustachian tube 202. The pressure detector 302A is used to acquire the air pressure of the external auditory canal 208. The control module 304 is also used to: determine that the Eustachian tube 202 is open when the detected air pressure of the external auditory canal 208 is greater than the initial air pressure, and control the air delivery module 306 to stop delivering air; and determine that the Eustachian tube 202 is closed when the detected air pressure of the external auditory canal 208 drops to less than or equal to the initial air pressure, and control the air delivery module 306 to continue delivering air.

[0052] In this embodiment, as one implementation of the acquisition module 302, the barometric pressure detector 302A is used as the acquisition module 302. The shape of the barometric pressure detector 302A is set as an in-ear probe structure. As can be seen from the above description of the Eustachian tube 202, the Eustachian tube 202 and the external auditory canal 208 are separated by the tympanic membrane. Correspondingly, the gas parameter is the air pressure of the external auditory canal 208. The in-ear barometric pressure detector 302A can contact the skin of the external auditory canal 208 and close the external auditory canal 208 to acquire the air pressure of the external auditory canal 208.

[0053] Specifically, if the Eustachian tube 202 is open, under the action of the air supply device, when the Eustachian tube 202 is open, the airflow input by the air supply device enters the user's middle ear canal 204 through the Eustachian tube 202. The air pressure in the middle ear canal 204 gradually increases, making the air pressure in the middle ear canal 204 greater than the air pressure in the external auditory canal 208. This, in turn, compresses the tympanic membrane 206 into the external auditory canal 208. Figure 6 As shown, since the air pressure detector 302A closes the external auditory canal 208, the indentation of the tympanic membrane reduces the volume of the external auditory canal 208, thereby increasing the air pressure inside the external auditory canal 208. The air pressure detector 302A feeds back the detected air pressure of the external auditory canal 208 to the control module 304.

[0054] The control module 304 receives air pressure parameters from the acquisition module 302 in the external auditory canal 208. If the detected air pressure in the ear canal increases relative to the initial air pressure, it indicates that there is a risk of the Eustachian tube 202 being opened. At this time, the control module 306 stops supplying air to eliminate the positive pressure in the middle auditory canal 204 and allow the tympanic membrane to return to its original position. Figure 7 As shown, the Eustachian tube 202 can close automatically within a short time after the positive pressure is eliminated, preventing damage to the ear canal during the use of the breathing control component 30 and ensuring the continuous and reliable operation of the breathing control component 30, thereby improving the safety of using the breathing control component 30. In addition, the use of a barometer 302A as the acquisition module 302, and the determination of whether the Eustachian tube 202 is open based on the detected external auditory canal 208 pressure, has high detection accuracy and precision, which is conducive to obtaining a timely response from the air delivery module 306.

[0055] After the Eustachian tube 202 is closed, the air pressure detector 302A continuously collects the ear canal air pressure of the external auditory canal 208 and sends the ear canal air pressure to the control module 304. When the control module 304 detects that the ear canal air pressure has returned to the initial air pressure, it controls the air delivery module 306 to start air delivery again so that the breathing control component 30 can resume operation in a timely manner.

[0056] Optionally, the acquisition module 302 further includes an ear hook structure connected to the in-ear structure, the ear hook structure being used to hang on the user's auricle.

[0057] In this embodiment, by further adding an ear hook structure to the in-ear structure, the ease of use of the acquisition module 302 is improved.

[0058] In addition, there are two acquisition modules 302, which are inserted into the user's left and right ears respectively. When the air pressure detected by either acquisition module 302 rises from the initial air pressure or falls back to the initial air pressure, the control module 304 generates a control command for the air delivery module 306 so that the state of the air delivery module 306 is adapted to the change in air pressure in the external auditory canal 208.

[0059] In some embodiments, the acquisition module 302 includes a sound wave detector and a patch structure for accommodating the sound wave detector. The sound wave detector is used to acquire sound wave information of respiratory airflow. The control module 304 is used to: determine that the Eustachian tube 202 is open and control the air delivery module 306 to stop air delivery when the matching degree between the detected waveform of the sound wave information and the preset waveform is less than a preset matching threshold; and determine that the Eustachian tube 202 is closed and control the air delivery module 306 to continue air delivery when the matching degree is greater than or equal to the preset matching threshold.

[0060] In this embodiment, as another implementation of the acquisition module 302, since there are audio parameters in the breathing airflow, a sound wave detector can be used as the acquisition module 302 to determine whether the Eustachian tube 202 is open by detecting the sound wave changes in the user's breathing airflow.

[0061] Specifically, the sound wave detector is designed as a patch that is attached to the user's face, neck, or ear during use. Sound waves are transmitted to the detector through the user's bones and flesh. When the Eustachian tube 202 is closed, airflow passes only through the nasal cavity and / or oral cavity, and the sound waves of the breath are transmitted to the detector through the user's bones and flesh. The waveform information of the sound waves collected by the detector when the Eustachian tube 202 is closed is stored as a preset waveform. When the Eustachian tube 202 is open, airflow passes through the nasal cavity and / or oral cavity, as well as the Eustachian tube 202, and the sound wave information of the breath is transmitted to the detector through the user's bones and flesh.

[0062] The control module 304 compares the waveform of the received sound wave information with the preset waveform. Since the sound wave waveform of the user's normal breathing airflow has certain fluctuations, when the waveform information of the breathing gas is collected in real time, the matching degree between the waveform of the sound wave information and the preset waveform is detected to determine whether the user's breathing frequency parameters have large fluctuations based on the waveform of the sound wave information. Then, if a large fluctuation is detected, that is, if the matching degree is less than the preset matching threshold, the eustachian tube 202 is determined to be open, and if the matching degree is greater than or equal to the preset threshold, the eustachian tube 202 is determined to be closed.

[0063] When the Eustachian tube 202 is open, the control air delivery module 306 stops delivering air; when the Eustachian tube 202 is closed, the control air delivery module 306 continues delivering air. The sound wave detector is used as the acquisition module 302. The sound wave detector, which is set as a patch structure, can be attached to the user's face, neck, or ear with an adhesive material. While realizing the function of detecting the opening and closing of the Eustachian tube 202, the acquisition method has high convenience.

[0064] Specifically, waveform information can include information such as the amplitude, frequency, and period of the sound wave.

[0065] In some embodiments, the breathing control component 30 specifically includes a data acquisition module 302, a control module 304, a gas delivery module 306, and a prompting module. The data acquisition module 302 is communicatively connected to the control module 304, the control module 304 is communicatively connected to the gas delivery module 306, and the prompting module is communicatively connected to the control module 304. The prompting module is used to send a prompting message when the control module 304 determines that the Eustachian tube 202 is open.

[0066] In this embodiment, by adding a setting prompt module, while realizing the adaptive configuration of the gas delivery module 306's gas delivery status, prompt information is generated, which can remind other personnel that the current user has a risk of the Eustachian tube 202 being open. This helps to further reduce the risk of the user's Eustachian tube 202 being in a continuously open state, thereby further improving the safety of using the breathing control component 30.

[0067] Specifically, the prompting module can be at least one of a buzzer, a speaker, a display screen, and a communication device.

[0068] like Figure 5 As shown, in some embodiments, the breathing control component 30 specifically includes a data acquisition module 302, a control module 304, and a gas delivery module 306 that are connected in sequence. The gas delivery module 306 includes an airflow generator 3062 and a controlled device that are connected in sequence, and a gas delivery pipe 3064 connected to the airflow generator 3062. The controlled device is connected in sequence to the control module 304. The controlled device receives control parameters from the control module 304 to control the airflow generator 3062 to deliver gas or stop delivering gas through the gas delivery pipe 3064 according to the control parameters.

[0069] Specifically, the acquisition module 302 may include a barometric pressure detector 302A and an in-ear structure for housing the barometric pressure detector 302A. The gas parameter is the air pressure of the external auditory canal 208 connected to the Eustachian tube 202. The barometric pressure detector 302A is used to acquire the air pressure of the external auditory canal 208.

[0070] Alternatively, the acquisition module 302 may include a sound wave detector and a patch structure for accommodating the sound wave detector, the sound wave detector being used to acquire sound wave information of respiratory airflow.

[0071] Those skilled in the art will understand that the controlled device can be a device inside the airflow generator 3062 or a device outside the airflow generator 3062. The controlled device controls the airflow generator 3062 to supply or stop supplying air through the air supply pipe 3064 by receiving control parameters sent by the control module 304. Specifically, this can be achieved by controlling the airflow generator 3062 to run or stop, or by controlling the air supply pipe 3064 to open or close, so as to quickly eliminate the positive pressure in the Eustachian tube 202 and close it.

[0072] In some embodiments, the controlled device is a switch controller for an airflow generator 3062. One end of an air supply pipe 3064 is connected to the airflow generator 3062, and the other end of the air supply pipe 3064 is used to supply air to the user. When the Eustachian tube 202 is open, the control parameters are used to control the switch controller to turn off the airflow generator 3062. When the Eustachian tube 202 is closed, the control parameters are used to control the switch controller to turn on the airflow generator 3062.

[0073] In this embodiment, as a simple control method, the switch controller of the airflow generator 3062 is used as the controlled device, so that the airflow generator 3062 is directly controlled by the control module 304, thereby enabling direct and reliable control of the air delivery state.

[0074] In some embodiments, the controlled device is a control valve 3066, which is used to control the opening or closing of the air supply tube 3064. When the Eustachian tube 202 is open, the control parameters are used to control the closing of the control valve 3066. When the Eustachian tube 202 is closed, the control parameters are used to control the opening of the control valve 3066.

[0075] In this embodiment, as another simple control method, a control valve 3066 is set on the air supply tube 3064 and the control valve 3066 is used as a controlled device. When the Eustachian tube 202 is detected to be open, only the air supply tube 3064 is shut off. At this time, the airflow generator 3062 can still be in operation. When it is determined that the Eustachian tube 202 is closed, the air supply tube 3064 is opened so that the airflow can be delivered to the user in a timely manner. This method can minimize the impact of stopping the air supply on the user, thereby ensuring the safety and reliability of the breathing control component 30 during use.

[0076] Reference Figure 8 The diagram shows a structural block diagram of a ventilation therapy device according to an embodiment of the present invention, which may specifically include the following modules: a breathing mask 40; and a breathing control component 30 as described in any of the above embodiments. The breathing control component 30 includes an air supply tube 3064 and an airflow generator 3062. One end of the air supply tube 3064 is connected to the breathing mask 40, and the other end of the air supply tube 3064 is connected to the airflow generator 3062.

[0077] Specifically, the ventilation therapy device includes a breathing mask 40, a data acquisition module 302, a control module 304, and a gas delivery module 306. The data acquisition module 302 may include a pressure sensor 302A and / or a sound wave detector. For the pressure sensor, the pressure sensor 302A is configured as an in-ear structure, and the gas parameter is the pressure of the external auditory canal 208 connected to the Eustachian tube 202. The pressure sensor 302A is used to acquire the pressure of the external auditory canal 208. When the control module 304 detects that the pressure in the external auditory canal 208 is greater than the initial pressure, it determines that the Eustachian tube 202 is open and controls the gas delivery module 306 to stop delivering gas. If the air pressure in the external auditory canal 208 drops to less than or equal to the initial air pressure, the Eustachian tube 202 is determined to be closed, and the air delivery module 306 is controlled to continue delivering air. For the sound wave detector, which is set as a patch structure, the sound wave detector is used to collect the sound wave information of the respiratory airflow. If the matching degree between the waveform of the sound wave information and the preset waveform is less than the preset matching threshold, the Eustachian tube 202 is determined to be open, and the air delivery module 306 is controlled to stop delivering air. If the matching degree is greater than or equal to the preset matching threshold, the Eustachian tube 202 is determined to be closed, and the air delivery module 306 is controlled to continue delivering air.

[0078] The breathing mask 40 can be any one of the following: a nasal mask that only covers the nose, a mouth mask that only covers the mouth, a mouth-nose mask that covers both the mouth and nose (also known as a full-face mask), or a nasal pad mask that is inserted into the nostrils.

[0079] In this embodiment, the gas parameters of the user's Eustachian tube 202 collected by the acquisition module 302 are transmitted to the control module 304. The control module 304 can determine whether the Eustachian tube 202 is in an open or closed state based on whether the gas parameters change. If the Eustachian tube 202 is in an open state, the control module 304 generates a control command to stop the gas delivery module 306 from delivering gas to eliminate the positive pressure in the Eustachian tube 202, thereby causing the Eustachian tube 202 to close automatically. If the Eustachian tube 202 is in a closed state, the control module 304 generates a control command to continue the gas delivery module 306 from delivering gas to the user so that the ventilation therapy device can continuously deliver gas to the user for treatment.

[0080] By setting up a ventilation therapy device with a data acquisition module 302, when treating users, the device can improve the reliability of operation for users with independent abilities, thereby enhancing the treatment effect. For users without independent abilities, the device can prevent the risk of problems such as ear perforation and hearing loss during treatment, thus improving operational safety.

[0081] Optionally, the control module 304 can directly control the opening and closing of the airflow generator 3062 to control the gas delivery module 306 to deliver or stop gas delivery.

[0082] Optionally, when the controlled device is a control valve 3066, the control valve 3066 is disposed on the gas supply pipe 3064, and / or disposed at the connection between the gas supply pipe 3064 and the breathing mask 40, and / or disposed at the connection between the gas supply pipe 3064 and the airflow generator 3062.

[0083] Specifically, the control valve 3066 is essentially a switch that controls the opening or closing of the air supply pipe 3064. It can be installed on the air supply pipe 3064, at the connection between the breathing mask 40 and the air supply pipe 3064, or at the connection between the air supply pipe 3064 and the airflow generator 3062. The opening and closing of the control valve 3066 is controlled by the control module 304. When the control module 304 issues a "close" command, the control valve 3066 closes, cutting off the air supply pipe 3064 and preventing airflow from the airflow generator 3062 from entering the user's airway; when the control module 304 issues an "open" command, the control valve 3066 opens, allowing normal air supply.
