Description
Technical Field
[0001] This invention relates to the field of ventilation therapy technology, and particularly to a ventilation mask and breathing device. Background Technology
[0002] Respiratory devices, including ventilating masks, are required in many areas of the clinical setting, particularly in the treatment of respiratory diseases. Respiratory devices may be used in MRI environments (e.g., MRI scans), where the very strong magnetic fields and alternating magnetic fields in the radiofrequency range can potentially affect the respiratory device or implanted devices in the patient. Therefore, a respiratory device that is close to the patient is needed. Summary of the Invention
[0003] The present invention provides a ventilation mask and breathing device for identifying at least one magnetic field.
[0004] According to a first aspect of the present invention, a ventilation mask is provided, wherein a magnetic field identification device is provided in the ventilation mask, the magnetic field identification device being located on the side of the ventilation mask closer to the patient or on the side farther from the patient, wherein the magnetic field identification device is configured to identify at least one magnetic field.
[0005] In one embodiment, the magnetic field identification device includes an identification module configured to detect magnetic flux density and / or magnetic field strength to identify at least one magnetic field.
[0006] In one embodiment, the identification module is configured to identify at least one magnetic field when the magnetic flux density exceeds a threshold or the average value of the magnetic flux density reaches a threshold.
[0007] In one implementation, the identification module is configured to identify one or more of the following regions:
[0008] Regions with magnetic flux density greater than or equal to the electrostatic magnetic field threshold are identified as electrostatic magnetic field regions.
[0009] Regions with magnetic flux density greater than the sudden magnetic field threshold are identified as sudden magnetic field regions; and

[0011] In one embodiment, the electrostatic magnetic field threshold is 0.5 mT, the sudden magnetic field threshold is 3 mT, and the occupational exposure threshold is 200 mT.
[0012] In one embodiment, the identification module is configured to identify magnetic fields by recognizing sound or light signals on at least three coordinate axes.
[0013] In one embodiment, the identification module is configured to continuously detect magnetic flux density according to an identification frequency, or
[0014] The identification module is configured to detect magnetic flux density intermittently at certain time intervals.
[0015] In one embodiment, the recognition frequency is 1s-10s.
[0016] In one embodiment, the magnetic field identification module further includes a storage module connected to the identification module, the storage module being configured to record one or more of the electrostatic magnetic field regions, sudden magnetic field regions, and average magnetic field regions of occupational exposure identified by the identification module.
[0017] In one embodiment, a prompting module is further included, which is connected to the recognition module. The prompting module is configured to emit one or more of the following signals in response to the recognition module recognizing one or more of an electrostatic magnetic field region, a sudden magnetic field region, and an average magnetic field region of occupational exposure: an sound signal, a light signal, a vibration signal, a thermal signal, and a stinging signal.
[0018] In one embodiment, the magnetic field identification device further includes an energy module, which is a light energy module and / or a battery.
[0019] In one embodiment, the magnetic field recognition device is embedded in the ventilation mask by assembly or injection molding, and when the ventilation mask is worn, the distance between the magnetic field recognition device and the patient's face is 5cm-10cm.
[0020] In one embodiment, the ventilation mask is a full-face mask, a nasal mask, or an oronasal mask, the ventilation mask including a pad and a frame connected to the pad, the pad being disposed on the side closer to the patient and the frame being disposed on the side farther from the patient.
[0021] In one embodiment, the ventilation mask further includes a bend, one end of which is connected to the pad or the frame, and the other end of which is used to connect to the air inlet pipe of a gas generator. The bend communicates with a chamber in the pad.

[0024] Compared with the prior art, the advantages of the present invention are that the magnetic field recognition device in the ventilation mask can recognize magnetic fields, thus it can be applied in the clinical MRI environment; and since the ventilation mask is worn on the patient's face, the ventilation mask and magnetic field recognition device are closer to the patient than active treatment devices such as ventilators, thus achieving a better magnetic field recognition position.

[0032] The invention will now be further described with reference to the accompanying drawings.
[0033] like Figure 1 and Figure 2 As shown, the present invention provides a ventilation mask 100, and more specifically, a ventilation mask 100 capable of recognizing magnetic fields, wherein the ventilation mask 100 is provided with a magnetic field recognition device 200. For example... Figure 1 As shown, the magnetic field identification device 200 is located on the side of the ventilation mask 100 closer to the patient or away from the patient, wherein the magnetic field identification device 200 is configured to identify at least one magnetic field, thereby being applicable in a clinical MRI environment.
[0034] Since the ventilation mask 100 is worn on the patient's face, the ventilation mask 100 and the magnetic field recognition device 200 are closer to the patient than active therapeutic devices such as ventilators. Therefore, integrating the magnetic field recognition device 200 into the ventilation mask 100 can achieve a better magnetic field recognition position. Furthermore, the ventilation mask 100 is much smaller in size than active therapeutic devices such as ventilators, so its own magnetic field is smaller. Under the same magnetic field recognition function, integrating the magnetic field recognition device 200 into the ventilation mask 100 has less impact on the entire therapeutic device.
[0035] like Figure 2 As shown, the magnetic field identification device 200 includes an energy module 201, an identification module 202, a storage module 203, and a prompting module 204. The energy module 201 is electrically connected to the identification module 202, the storage module 203, and the prompting module 204, respectively, and provides power to these modules. The identification module 202 is configured to detect magnetic flux density and / or magnetic field strength to identify at least one magnetic field. The identification module 202 is communicatively connected to the storage module 203 and the prompting module 204. The storage module 203 can store data in response to the identification by the identification module 202, and the prompting module 204 can issue a prompt signal in response to the identification by the identification module 202.
[0036] The energy module 201 can be a solar energy module or a battery (such as a button cell battery). Specifically, when the magnetic field recognition device 200 is located on the side of the ventilation mask 100 furthest from the patient (i.e., on the outer side of the ventilation mask), the energy module 201 can be a solar energy module to power other modules using solar and light energy. When the magnetic field recognition device 200 is located on the side of the ventilation mask 100 closest to the patient (i.e., on the inner side of the ventilation mask), the energy module 201 can be a button cell battery.
[0037] The identification module 202 may include one or more sensors, for example. The sensors may be one or more of a magnetometer, a magnetic field sensor, a Hall sensor, a Tesla sensor, a Gauss sensor, a reed switch sensor, and a measuring coil.
[0038] The identification module 202 is configured to identify magnetic fields by recognizing sound or light signals on at least three coordinate axes. These three coordinate axes can be, for example, the X, Y, and Z axes in a Cartesian coordinate system. The identification module 202 has a acquisition head, which can be located on the outer surface of the ventilation mask 100 to facilitate the identification of sound or light signals in the environment.
[0039] The identification module 202 is configured to identify at least one magnetic field when the magnetic flux density exceeds a threshold or the average value of the magnetic flux density reaches a threshold. The threshold is a safety value set in the identification module 202. If the magnetic flux density identified by the identification module 202 reaches or exceeds this safety value, it indicates that the patient wearing the ventilation mask 100 is in an unsafe environment. Furthermore, when the identification module 202 identifies that the magnetic flux density on one of the coordinate axes reaches or exceeds this safety value, it can be considered that the patient wearing the ventilation mask 100 is in an unsafe environment.
[0040] For example, the identification module 202 can identify areas with magnetic flux density greater than or equal to the electrostatic magnetic field threshold as electrostatic magnetic field regions. The electrostatic magnetic field threshold is 0.5 mT. That is, when the magnetic flux density in the environment is greater than or equal to 0.5 mT, the identification module 202 can identify that environmental area as an electrostatic magnetic field region. The identification module 202 can also identify areas with magnetic flux density greater than the sudden magnetic field threshold as sudden magnetic field regions. The sudden magnetic field threshold is 3 mT. That is, when the sudden magnetic flux density in the environment is greater than or equal to 3 mT at a certain moment, the identification module 202 can identify that environmental area as a sudden magnetic field region. The identification module 202 can also identify areas where the average magnetic flux density reaches the occupational exposure threshold as average magnetic field regions of occupational exposure. The occupational exposure threshold is 200 mT. That is, when the average magnetic flux density in the environment over a certain period (e.g., 8h, 10h, 12h) is 200 mT, the identification module 202 can identify that environmental area as an average magnetic field region of occupational exposure.
[0041] Preferably, the identification module 202 can continuously detect magnetic flux density according to the identification frequency during identification. For example, the identification frequency is 1s-10s. The higher the identification frequency, the more stringent the performance requirements of each module of the magnetic field identification device 200.
[0042] Optionally, the identification module 202 can also detect magnetic flux density intermittently at certain time intervals. These time intervals can be regular or irregular.
[0043] The identification module 202 can identify a magnetic field area with a diameter of 2 inches (50 mm). Since the patient wearing the ventilation mask 100 is considered the center, the magnetic object needs to be at least 2 inches (50 mm) away from the patient to avoid the local magnetic field from having any possible impact on the patient.
[0044] When the identification module 202 identifies an electrostatic magnetic field region, a sudden magnetic field region, and an average magnetic field region of occupational exposure, the storage module 203 can record one or more of these regions. The storage device 20 may include, for example, at least one hard disk drive and / or at least one memory card and / or similar storage media.
[0045] The alert module 204 is configured to emit one or more of the following signals in response to the recognition module 202 detecting one or more of an electrostatic magnetic field area, a sudden magnetic field area, and an average magnetic field area of occupational exposure: an audible signal, an optical signal, a vibration signal, a thermal signal, and a stinging signal. Specifically, when the magnetic field recognition device 200 is located on the side of the ventilation mask 100 furthest from the patient (i.e., outside the ventilation mask), the alert module 204 can emit an audible signal and / or an optical signal for warning. When the magnetic field recognition device 200 is located on the side of the ventilation mask 100 closest to the patient (i.e., inside the ventilation mask), the alert module 204 can emit one or more of the following signals in addition to an audible signal and / or an optical signal: a vibration signal, a thermal signal, and a stinging signal. These signals can all act on the face of the patient wearing the ventilation mask 100, thus serving as a warning.
[0046] When the prompt module 204 issues the above signal, it indicates that the magnetic flux density in the environment has exceeded the safety value set in the identification module 202, meaning that the patient wearing the ventilation mask 100 is in an unsafe environment.
[0047] The alert module 204 may include, for example, a sound signal generator for emitting a sound signal. The sound signal may be in the form of a tone, a tone sequence, an alarm, voice output, etc. To generate the sound signal, the alert module 204 may also include at least one speaker. The speaker can emit a warning tone to provide an alert.
[0048] The alert module 204 may also include an illumination device (e.g., an LED light) for emitting light signals, which may emit light of different colors and / or intensities. The light signal 33 may be implemented, for example, by emitting light through at least one LED light. For example, the LED light may flash, illuminate continuously, or change color to provide an alert.
[0049] The prompt module 204 can be connected to a control switch, which can be manually operated to turn off various signals such as sound signals, light signals, vibration signals, heat signals, and tingling signals.
[0050] The magnetic field recognition device 200 can be embedded in the ventilation mask 100, for example, by assembly or injection molding. Specifically, when the ventilation mask 100 is worn, the distance between the magnetic field recognition device 200 and the patient's face is 5cm-10cm. Within this distance range, it is ensured that the magnetic field recognition device 200 itself will not interfere with the normal operation of any implanted devices in the patient's body (such as pacemakers, defibrillators, and cochlear implants), while also ensuring the closest possible distance to the patient for optimal recognition results.
[0051] Furthermore, the distance between the magnetic field recognition device 200 and the patient's face is 0.5cm-5cm, and this approach is suitable for patients without implanted devices in their bodies.
[0052] The magnetic field identification device 200 is embedded in the ventilation mask 100. Since the ventilation mask 100 is made of non-metallic materials such as silicone and plastic, it can shield or weaken the magnetic field of the magnetic field identification device 200. The magnetic flux density of the magnetic field identification device 200 itself is generally less than 400 mT.
[0053] The magnetic field identification device 200 is independent of whether the ventilation mask 100 is working. That is, the magnetic field identification device 200 can perform magnetic field identification when the ventilation mask 100 is working, and it can also perform magnetic field identification when the ventilation mask 100 is not working.
[0054] The ventilation mask 100 can be a full-face mask, a nose mask, or a mouth and nose mask.
[0055] like Figure 1 As shown, the ventilation mask 100 includes a pad 1 and a frame 2 connected to the pad 1. The pad 1 is positioned on the side closer to the patient and is used to create a seal against the patient's face. The frame 2 is positioned on the side farther from the patient and is used to support the pad 1.
[0056] The ventilation mask 100 also includes a bend 4, one end of which is connected to the pad 1 or the frame 2, and the other end of which is used to connect to the air inlet line of a gas generator. The bend 4 communicates with a chamber in the pad 1. Ventilation gas can enter the chamber of the pad 1 through the air inlet line and the bend 4 for the patient to breathe.
[0057] like Figure 1 As shown, the ventilation mask 100 also includes a headband 3, which is connected to the frame 2 and is used to fix the ventilation mask 100 to the patient's face.
[0058] The magnetic field identification device 200 can be disposed on one or more components of the ventilation mask 100. For example, the magnetic field identification device 200 can be disposed on one or more of the frame 2, the pad 1, the bend 4, or the headband 3. The magnetic field identification device 200 can be disposed on one or more of the frame 2, the pad 1, the bend 4, or the headband 3 by assembly (or injection molding).
[0059] Alternatively, the magnetic field identification device 200 can be disposed inside one or more components of the ventilated mask 100. For example, the magnetic field identification device 200 can be disposed inside one or more of the frame 2, pad 1, bend 4 or headband 3. The magnetic field identification device 200 can be disposed inside one or more of the frame 2, pad 1, bend 4 or headband 3 by injection molding (or assembly).
[0060] Understandably, the ventilation mask 100 may also include other components for achieving its necessary functions, for example, the structure and implementation of these components may be obtained from the prior art.
[0061] The present invention also provides a breathing device, including the aforementioned ventilation mask, a gas generator, and an air inlet pipe connected to the gas generator, the air inlet pipe being in fluid communication with the ventilation mask. The gas generator may be, for example, a ventilator, which may employ various structural forms existing in the art.
[0062] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
