Description

Technical Field

[0001] (Cross - Reference to Related Applications) This patent application claims the priority of U.S. Provisional Application No. 63 / 074,144, filed on September 3, 2020, which is incorporated herein by reference in its entirety.

[0002] The present invention relates to a modular communication device for use in combination with masks, mouth, nose, face, and head covers. Modern social and health concerns often require the use of such covers and / or masks to protect the wearer from exposure to external air, liquids, particles, pathogens, or other harmful substances. While masks can protect the wearer, they also interfere with communication by reducing or buffering the wearer's voice. The present disclosure provides a modular communication device that can be attached to a disposable or reusable mask and enables the user's voice to be amplified outside the mask.

Background Art

[0003] The present disclosure relates to modular communication devices for use in combination with face masks and / or covers, including examples with N95 respirators, surgical, surgical, and cloth masks, face shields, cloth covers such as bandanas, and continuous positive airway pressure (CPAP) or other (e.g., bilevel positive airway pressure (BiPAP)) devices including masks and hoods. These modular communication devices may include a microphone, which is configured to interface with a wired or wireless speaker and / or a wired or wireless communication device such as a telephone.

[0004] In almost all settings, the use of a face mask and / or cover limits the ability to communicate naturally, and clear conversations with others or over the phone are generally difficult. This difficulty is due, at least in part, to intervening plastic, fabric, or other materials, and to air flow and mechanical and other environmental noises.

[0005] Therefore, in the art, there is a need for a modular communication device configured to receive speech from a mask wearer from within the mask or associated accessories, utilizing one or more microphones, and transmitting that speech to a speaker or other communication device so that the person's voice can be heard. This communication capability / device may take the form of a coupler, a pair of magnetizing devices, a clip-on or pin-on attachment, a bone conduction microphone device, a throat microphone device, or many other such exemplary implementations.

[0045] Detailed explanation Details of one or more embodiments of the present invention are described below in the accompanying description. Any materials and methods similar to or comparable to those described herein may be used in the practice or testing of the present invention, but preferred materials and methods are described herein. Other features, purposes, and benefits of the present invention will be apparent from the description. In this description, singular forms also include plural forms unless the context clearly determines otherwise. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present invention belongs. In case of any conflict, this description shall prevail.

[0046] As described above, the Disclosure relates to a patient breathing mask, in some embodiments including a microphone positioned thereon, wherein the microphone is configured to interface with a wired or wireless speaker and / or wired or wireless communication device, such as a telephone. In some embodiments, the Disclosure relates to a modular communication device for use with a mouth, nose, face, and head cover, including a mask. The Disclosure provides a modular communication device that can be attached to a disposable or reusable mask or face cover and may allow the user's voice to be amplified outside the mask. The Disclosure is described below with reference to various exemplary embodiments, but is not limited thereto.

[0047] In some exemplary embodiments, the microphone is a noise-canceling microphone. In further embodiments, the microphone includes or is associated with at least one noise filter. In further exemplary embodiments, one or more of the microphone, speaker, and communication device are wireless. Any reference to a component such as a microphone, speaker that is wireless or transmits wirelessly should be understood to include a configuration in which such a device is connected to a component including a wireless transmitter and / or receiver. Thus, any reference in this specification to a “wireless” component should be read as including such a configuration. In further exemplary embodiments, the onboard speaker is integrated into part of the breathing mask. In further exemplary embodiments, the speaker is located outside the mask.

[0048] As mentioned above, in exemplary embodiments, the patient breathing mask includes an internal and / or coupling or tube-fitted noise-canceling microphone with wireless, e.g., Bluetooth® capability. In exemplary embodiments, the microphone is attached to or integrated into the breathing mask, a coupling designed to be attached to the mask tube interface, or a mask fluid delivery tube (e.g., for oxygen, air, or some other gas). In additional exemplary embodiments, the coupling includes one or more of the microphone, speaker, wiring, processor, and communication device. In exemplary embodiments, one or more of the preceding elements are embedded in or provided through part of the coupling.

[0049] As discussed above, in further exemplary embodiments, a microphone wirelessly transmits a patient's voice via Bluetooth® technology to a Bluetooth® speaker located in close proximity to and communicating with a Bluetooth® transmitter. References herein to "Bluetooth®" devices refer to devices that enable the use of Bluetooth® technology. In further exemplary embodiments, a microphone wirelessly transmits a patient's voice via Bluetooth® technology to a Bluetooth® speaker and / or a Bluetooth® smartphone located in close proximity to and communicating with a Bluetooth® transmitter. While a Bluetooth® speaker and an exemplary Bluetooth® smartphone are described specifically, this disclosure also assumes other Bluetooth® communication devices.

[0050] Referring here to Figure 1, an exemplary patient breathing mask according to this disclosure includes an exemplary microphone provided therein. In an exemplary embodiment, the breathing mask is a CPAP (or BIPAP) breathing mask (generally shown in 10) comprising a mask portion 12 and a Bluetooth® microphone 14 incorporated in a fluid gap (generally shown in 16) of the mask 10 near the patient's mouth (not shown). The exemplary mask also includes a fluid delivery tube 18 and at least one mask inlet 20.

[0051] In an exemplary embodiment, the microphone 14 is mounted on or provided within the material of the mask. In another exemplary embodiment, the microphone is provided within a separate microphone tube (not shown) which may extend at least partially into the fluid space of the mask 10. In a further exemplary embodiment, the microphone tube is at least partially sealed via a plastic or membrane that is at least moderately permeable to sound, but also separately maintains the integrity of the fluid air space 16 within the breathing mask 10.

[0052] Such exemplary microphone tubes may be provided within or mounted within the breathing mask 10, the intermediate fluid delivery tube 18, or any coupling 22 or part thereof interposed in the fluid delivery tube 18 of the breathing mask 10.

[0053] Referring here to Figure 2, another exemplary patient breathing mask 10 incorporates such a Bluetooth® microphone 14 in a coupling device 22 positioned between the fluid delivery tube 18 and the breathing mask 10. In the exemplary embodiment, the coupling 22 is sized and configured to provide a friction fit to the mask inlet 20 on one side and to the fluid delivery tube 18 on the other side. Referring to Figure 3, the exemplary coupling 22 includes a mask inlet side (generally shown at 32) and a fluid delivery tube side (generally shown at 34), with the bulk airflow traversing the inside of the tube (generally indicated by the arrows at 36).

[0054] In an exemplary embodiment, the microphone 14 is isolated from the bulk airflow 36 by a filter 38, which may be configured to filter out one or more sonic characteristics or simply shield the microphone from the bulk airflow. The filter 38 may be a membrane, an acoustic mesh, or any other convenient sound transmission material.

[0055] In the illustrated exemplary embodiment, the microphone is illustrated as being operably connected to a microphone preamplifier 40, equalization components 42 [e.g., an analog-to-digital converter (ADC) and a digital signal processor (DSP)], a Bluetooth® transmitter 44, sound output components such as a digital-to-analog converter (DAC), an amplifier (Amp) and a speaker 45, an antenna 46, and a power source 47 such as a battery or a wired power adapter. These components are illustrated in this exemplary embodiment as both those connected to the microphone and those housed on the protruding portion 48 of the coupler 22. However, it should be recognized that the microphone may be configured onboard the coupler 22 with more or fewer associated components, with some components or processes omitted or performed in any location, for example, outside the coupler 22, remotely from the coupler 22, etc.

[0056] In addition, the coupling can take any convenient shape when housing such components, as long as the connecting portions 32 and 34 are configured to connect to the mask inlet 20 and the fluid delivery tube 18, respectively.

[0057] In exemplary embodiments, the coupler may be configured to attach to the fluid delivery tube regardless of any variation in tube diameter (e.g., differences in configurations that make the use of a 19 mm standard tube versus a 15 mm tapered tube reasonable). Thus, exemplary embodiments provide a universal fitting (e.g., a clip-type as shown in Figure 4) that is configured to fit a variety of tubes and breathing apparatuses.

[0058] In other exemplary embodiments, the microphone or other electronic component is configured to be mounted externally to the breathing mask 10 but in close proximity to the patient's fluid gap (see 16 in Figure 1) (for example, as a clip-type attachment). Referring here to Figure 4A, a clip 50 is illustrated together with a microphone unit 14 provided on the underside of the clip. In exemplary embodiments, the clip 50 also interfaces with power and signal wires 54 via a port 56. Such a clip may be configured to be mounted at any location where it is convenient to place the microphone unit 14 near the sound transmission surface, for example, the inlet portion 20 of the mask 10 or an external portion of the coupling 22, but Figure 4 illustrates the provision of the clip 50 over a portion of the fluid delivery hose 18, pressed against or in close proximity to the material of the hose so that the microphone unit senses vibrations of sound transmitted through the hose. Figure 4 illustrates a wired configuration, but it should be noted that the microphone unit may also be configured with a battery and a wireless (e.g., Bluetooth®) transmitter. Figure 4B shows an exemplary side view of the clip 50 positioned near the tube 18 at the location where the microphone 14 is installed.

[0059] Referring here to Figure 5, the fluid delivery tube 18 is illustrated to include an integrated coupler 22 that incorporates a microphone 14 (see Figure 2) and is attachable to or integrated with the breathing fluid delivery tube 18. An exemplary power cord 24 extends to the microphone 14 (which may be wired or wireless, for example, configured in a Bluetooth® array) along at least a portion of the tube 18. As described above, the coupler may also include other components such as processing or filtering components, a speaker, a wireless transmitter, wiring, or any other type of communication device in addition to or as an alternative to the microphone.

[0060] In further embodiments, the microphone 14 may be configured as a wired microphone that utilizes the exemplary code 24 or another code for data transmission. In additional exemplary embodiments, the microphone may be wireless and connected to a battery source, with the cord not extending along any portion of the conduit 18.

[0061] In further embodiments, the cord may be configured with one or more clips to secure it to the hose 18 or as an integral part of the hose 18, for example, embedded in or permanently attached to the conduit 18 or conduit wiring harness. An exemplary wire harness clip 62 is illustrated in Figure 6 as attaching the cord 24 to the conduit 18. In exemplary embodiments, the cord 24 is configured as a wiring harness secured at one or more locations via the harness clip 62, using a cord connectable to a coupler 22 (as in Figures 2 and 3) or a mask (as in Figure 1). With respect to any wired configuration, the end of the cord 24 (far from the mask) may be configured to connect to additional components such as speakers, processors, networks, power supplies, etc.

[0062] The device of the present invention may comprise several components. Figure 11 is a block diagram illustrating various components of an embodiment of the present invention. In this embodiment, a microphone, a microphone amplifier, a digital signal processor, a speaker amplifier, and a speaker are shown. A battery, battery management, a voltage regulator, or a USB are also present. Other embodiments and configurations may also be available.

[0063] Figure 12 shows an alternative embodiment of the device of the present invention, which shows a flat-connection flexible cable with a microphone module and a speaker module that can be attached by the mask user, as shown in Figure 13. The microphone module portion is intended to engage with a mask clip that can be magnetically engaged for attachment to a mask interposed between them.

[0067] During use, the device is relatively small and lightweight, weighing, for example, no more than approximately 25 grams and no more than approximately 17 grams. Figure 17 is a photograph showing an embodiment of the device clipped to the outer front of a mask.

[0068] The device's compact nature makes it ideal for long-term use. Figure 18 is a diagram of an embodiment of the device showing the speaker. Not shown are the microphone on the back of the device and the Bluetooth® device internals. A further exploded view of the embodiment of the device in Figure 18, as shown in Figure 19, depicts the housing and the mask clip with a hanging loop [also called a pull tab].

[0069] The device components are fitted neatly and compactly into a housing designed to engage with a mask clip. This is illustrated in an exploded view of the embodiment, as shown in Figure 20. In this embodiment, both the housing and the mask clip are shown with magnets. However, in other embodiments, a single magnet may be employed to aesthetically couple with ferromagnetic or ferrimagnetic components. A further embodiment of the present invention is an "L-shaped" device having an "L-shaped" housing and a corresponding "L-shaped" mask clip that engage with each other and are designed to attach the device to a mask. Figures 21 and 22 are photographs showing embodiments of the "L-shaped" device clipped to the bottom of a disposable mask on the user's chin. Figure 23 is a drawing of an embodiment of the L-shaped device attached to the bottom of a mask on the front outer surface of the mask.

[0070] The "L-shaped" device is compact and lightweight, generally weighing no more than approximately 25 grams, and even less than approximately 17 grams. Figure 24 is a drawing of an embodiment of the L-shaped device, shown with the housing coupled [engaged] to the mask clip. During use, the mask will be placed between them. The device may have various dimensions, and Figure 25 illustrates some of these in millimeters (inches in parentheses). Referring to Figure 26, additional details and arrangement of the device components are shown in an exploded view.

[0071] The embodiments envision a non-rechargeable battery-powered Bluetooth® microphone, and a rechargeable battery Bluetooth® microphone, or a directly corded microphone (providing constant power), using a port, cable, or wireless connection for recharging via an external power source.

In exemplary embodiments, one or more components, such as the mask, coupler, or hose, are configured as disposable products and have a predetermined service life. In further exemplary embodiments, a life indicator may be used to identify the end of the service life of the respirator mask, determined from unpacking from a sterile field. In further embodiments, a battery communicating with the microphone is configured to expire or switch off at the end of the service life of the respirator mask.

[0073] In additional embodiments where one or more components are provided in the coupler described above, such coupler may also, or alternatively, include one or more lifetime indicators.

[0074] In other embodiments, the patient breathing mask and / or fluid delivery tube is configured to be reusable with the Bluetooth® microphone at least partially water-resistant. In further embodiments, the Bluetooth® microphone is waterproof or housed in a waterproof enclosure. In such exemplary embodiments, the patient breathing mask and / or tube may be configured with a Bluetooth® microphone configured to withstand cleaning via the use of cleaning agents, e.g., enzymatic cleaning solutions, rinses, disinfectants, and pasteurizers. Further exemplary embodiments provide a Bluetooth® microphone or microphone enclosure configured to withstand the effects of cleaning and drying in public facilities or other stations.

The disclosed communication device, when used in conjunction with a mask and when using a telephone or other communication device, enables disposable or reusable masks to improve the user's communication from a safe distance.

[0084] Masks may be made from cloth, paper, cardboard, plastic, or other materials. Masks may be used to conceal the user's identity, or to prevent the dispersal of gases, liquids, or particulate matter that the user breathes or exhales. Masks may also protect the user from inhaling or receiving other gases, liquids, or other particulate matter on their face. Examples of masks include cloth masks, fabric masks, disposable masks, single-use masks, surgical masks, surgical masks, medical masks, plastic masks, dust masks, filter masks, respirator masks, breathing masks, oxygen masks, KN95 masks, N95 masks, surgical N95 masks, N99 masks, KN99 masks, N100 masks, KN100 masks, R95 masks, P95 masks, P100 masks, PM2.5 masks, FFP1 masks, FFP2 masks, FFP3 masks, CPAP masks, BiPAP masks, multilayer masks, masks with removable filters, face covers, handkerchiefs, scarves, veils, hoods, bandanas, masks with attachments, masks with fasteners, and combinations and layered arrangements thereof, selected from the group.

[0085] The communication device may be detachably attached to a disposable or reusable mask, which is particularly useful for healthcare professionals, patients, first responders, or anyone who wishes to cover their nose and mouth and / or filter the air they breathe or exhale. The communication device may be reusable so that it can be removed from a first mask to a subsequent mask. In some embodiments, the communication device may be modular, comprising multiple components that enable it to be attached to a mask. The communication device may include an inner and outer housing, or just one inner or one outer housing. The communication device may be pressurized sterilizable, sterilizable, or disposable.

[0086] The inner and outer housings of the communication device may each contain any other necessary components for the successful operation of the communication device. The housings may be made of any suitable material for commercial, personal, or medical devices, such as plastic, metal, wood, or artificial or natural materials. Each housing may also include elements for securing the inner and outer housings to the mask and for providing a connection between the inner and outer housings. To connect the inner and outer housings to the mask, the inner and outer housings may include mechanical clips, springs, magnets, pins, hooks and loops, snaps, buttons, glue or other adhesives, zippers, stitches, threads, strings, staples, suction, or other fastening means. Some features (e.g., snaps, buttons, zippers) may be complementary to features on the mask. The housings may be configured to slide into and remain permanently located within a pocket or other means for fastening on the mask. The inner and outer housings may be configured to be attached to eyeglasses, a hat, or other wearable item, allowing the inner housing to be in close proximity to the user's mouth or nose.

[0087] The inner and outer housings, each enabling the inner and outer housings to be mounted to one another and separated by a mask, may include complementary magnetic fixtures that provide a fixed and movable connection on the mask. The magnetic fixtures may be rings on each housing, providing a fixed connection between the inner and outer housings and securely attaching the communication device to the mask. The complementary magnetic fixtures are paired with each other across the mask and still allow electrical signals to pass between the inner and outer housings. The complementary magnetic fixtures may be rings, or squares, or any other shape with a hollow center. The complementary magnetic fixtures may also be multiple complementary magnets on each of the inner and outer housings. The complementary magnetic fixtures may have the ability to mount images or otherwise present messages on the outer housing in the form of free text or advertisements.

[0088] The inner and outer elements may also be sized to complementary curved forms. The curved form of the inner element may be mounted inside the mask, extending from one side to the other, traversing the area in front of the user's mouth. The speaker may be positioned centrally between the two sides so that it is close to the user's mouth. Other features of the inner element, such as electrical and mounting features, may be positioned along the curved form on the side of the microphone. The curved outer element may be attached to the inner element by a magnetic fixture at a location complementary to the inner element. In other embodiments, the elements may be part of, or attached to, an inner support frame / bracket that supports the shape of the mask on the user's face.

[0089] The inner and outer enclosures may contain a power source. The power source may be located in both enclosures, or in only one of the enclosures. The power source may be a replaceable or rechargeable battery. Due to the proximity of the enclosures, power may flow from the powered enclosure to the non-powered enclosure through the mask via induction or other modalities. Alternatively, physical connections as described above may straddle the inner and outer elements to provide power to non-powered elements or to exchange data between elements. It is also conceivable that the device may mesh with a mask having existing ports (for airflow, etc.) that allow suitable paths for physical connections between the inner and outer elements.

[0090] One or both of the inner and outer enclosures may include ports and / or cables for power sources or power charging, or for data transmission. The ports and / or cables may connect the enclosure, elements, and devices to another system for data or signal processing, charging, external speakers or communications, or any other related systems.

[0091] The inner element is positioned inside the mask, close to the user's mouth, and is capable of easily receiving the user's voice. The inner element may act as a microphone and transmitter, or may include one. The inner element may transmit the user's voice signal to the outer element. The outer element may be detachably mounted on the outside of the mask. The outer element may include a transmitter, a receiver, and a speaker, which receive a signal from the inner element and then amplify the user's voice. The user's voice may be amplified through the speaker in the outer housing, or the inner or outer housing may also transmit the voice signal to an external speaker or system. The speaker in the outer housing may amplify the user's voice along with or in combination with an external speaker or system. The microphone, speaker, and electrical processing may include any of the elements described above. The speaker may include an amplified housing, such as a megaphone, to amplify the user's voice. The transmission of signals between the inner and outer elements may be wireless or via a physical connection between the elements. Wireless transmission between inner and outer elements is suitable for reusable or disposable masks. Transmission of electrical signals through physical connections may include elements extending from the inner or outer elements that penetrate through the disposable mask and physically and electrically connect with other elements of the inner or outer elements. These connections are suitable for disposable masks or may be used in conjunction with reusable masks.

[0092] The communication device may also include sensors for detecting ambient or exhausted gas mixtures or temperature. Monitoring gases and temperature, such as air quality, may be useful in patient respiratory therapy, for first responders, or in any scenario where the user requires a mask. The device may include a separate membrane or filter used to sample or analyze ambient or exhausted air quality in real time with respect to contaminants, particulate matter, or pathogens. The membrane may be removable, replaceable, or washable. Sensors within the device may include relative or absolute humidity sensors, temperature sensors, dew point sensors, enthalpy sensors, pressure sensors, barometric pressure sensors, flow rate sensors, oxygen sensors, carbon monoxide or dioxide sensors, nitrogen sensors, or combinations thereof. Sensors may detect or monitor properties not associated with air quality, and these sensors may include acoustic sensors, optical sensors, cameras, ambient temperature sensors, accelerometers, or any sensors related to the exhausted or ambient environment. Sensors may also be external to the device but may be connected to ports on one or both of the inner or outer housing.

[0093] During operation, the device may detect the user's voice or sound via a microphone and reproduce the sound via a speaker. The device may include a microphone, speaker, processor, battery (disposable or rechargeable), charging / data port, communication such as Bluetooth®, volume control, light source, light-emitting display (LED), camera, video screen, and measurement port with the capability to electronically measure respiration (and / or vapors emanating from the user's mouth), noise, speech, tone, etc. The microphone may be noise-canceling. The device may provide communication between internal and external elements and any external systems by any wired connection or wireless connection such as RFID, WiFi, Bluetooth®, Zigbee®, Zwave, 2G, 3G, 4G, 5G, or any reasonable later-developed wireless modality.

[0094] The device may also include a user feedback unit, such as headphones or in-ear components. The feedback unit may assist the user when their voice is heard. The feedback unit may also include an external microphone, which may be embedded in or connected to the external element but separated from it. An external speaker may transmit sound to the user's ears. The feedback unit may be sized and configured to include additional microphones at other locations around the user, such as the user's throat. The feedback unit may be useful in masks, helmets, or other items that cover or isolate the user's head.

[0095] This device is intended to include any other reasonable technologies, systems, or processes to assist communication between a user and another user. These technologies include microprocessors, microcontrollers, computer chips, programmable algorithms for processing device data (including sound), any components for capturing sound and human speech, speakers and any technologies used to amplify sound and human speech, noise cancellation technologies, wireless capabilities for communication between microphones and speakers, and between this device and remote devices (external speakers, portable / mobile phones, watches, computers, and televisions, etc.).
