The present disclosure generally relates to nose plugs that may, for example, be used in connection with underwater diving, nose clearing devices, and/or diving helmets to facilitate equalization of a diver's internal ear pressure.
When submerged in a body of water during a dive, a diver must equalize the internal fluid (e.g., air) pressure in their ears to avoid pain and injury. There are a variety of different pressure equalization maneuvers a diver may perform while submerged to accomplish this. One of these maneuvers involves the diver exhaling while plugging their mouth and nose, which results in air within the throat being pushed through the eustachian tubes and into the middle ears. This in turn equalizes and/or balances the internal fluid pressure within the diver's middle ears.
Generally, a diver is able to plug their mouth by simply using their fascial muscles to hold their mouth closed and/or press their lips together to seal the opening of their mouth. These same actions are also typically performed by a person when holding their breath for example. One of the simplest ways for a diver to plug their nose, and thus seal their nasal passage, is to manually pinch their nose with their hand and/or fingers to collapse and block their nostrils, which in turn blocks and/or seals their nasal passage. However, certain types of diving equipment (e.g., a diving helmet, a full-face diving mask, an oral-nasal mask, etc.) covers at least a portion of the diver's face and/or nose, which prevents, blocks, restricts, and/or limits access to the diver's nose. The diver is therefore unable to reach, touch, and/or manually grasp their nose with their hands and/or fingers to plug their nose, and thereby seal their nasal passage, when diving with these types of equipment. As such, divers commonly use a nose clearing device (“NCD”) to assist in plugging their nose while diving.
Many current NCD designs include a nose block, pad, or other body that is arranged within the diving helmet and is pressed directly against the diver's nose to cover and/or block the nostril openings. It can be challenging to properly position the nose block relative to the nose so that it sufficiently contacts the nose to create an effective seal. In addition, the nose block often needs to be pressed against the nose with a large amount of force to achieve and maintain an effective seal while performing the equalization maneuver because the air exhaled by the user pushes against the nose block and can move the nose block partially out of contact with the nose, compromising the seal and resulting in the equalization maneuver being ineffective. Pressing the nose block against the nose with a large amount of force can be uncomfortable and painful, however, particularly during longer dives where the diver may need to perform the equalization maneuver a significant number of times.
Accordingly, there is a need for an improved nose clearing device that minimizes or eliminates one or more challenges or shortcomings of existing nose blocks for diving.
A nose plug for performing a pressure equalization maneuver while underwater diving may include a base, a first nasal insert, and a second nasal insert. The first nasal insert and/or the second nasal insert may project from the base. The first nasal insert may fit snuggly within and may protrude deeply into a first nostril of a user when in use such that airflow through the first nostril is prevented. The second nasal insert may fit snuggly within and may protrude deeply into a second nostril of a user when in use such that airflow through the second nostril is prevented. A nose clearing device and/or a diving helmet may include the nose plug.
While the claims are not limited to a specific illustration, an appreciation of various aspects may be gained through a discussion of various examples. The drawings are not necessarily to scale, and certain features may be exaggerated or hidden to better illustrate and explain an innovative aspect of an example. Further, the exemplary illustrations described herein are not exhaustive or otherwise limiting, and embodiments are not restricted to the precise form and configuration shown in the drawings or disclosed in the following detailed description. Exemplary illustrations are described in detail by referring to the drawings as follows:
Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various described embodiments. However, it will be apparent to one of ordinary skill in the art that the various described embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.
Disclosed is a nose plug 100 for use in connection with performing a pressure equalization maneuver while underwater diving. A diver may use the nose plug 100 to plug their nose to block and/or seal their nasal passage while performing an equalization maneuver to equalize their internal ear pressure during an underwater dive. The nose plug 100 is easy to properly position relative to the nose and provides an effective sealing and/or blockage of the nasal passage with less difficulty, effort, and discomfort than conventional NCDs. Compared to conventional NCDs, the disclosed nose plug 100 enables divers to more easily, quickly, comfortably, and effectively plug their nose while underwater diving, such as when performing a pressure equalization maneuver.
In examples, the nose plug 100 is structured as and/or part of a nose plug attachment 102 that is releasably attachable to a separate nose clearing device 20 (“NCD”), such as an existing NCD 20 owned by the diver and/or an NCD 20 that is part of, included with, and/or attachable to a diving helmet 10. For example, in
An NCD 20 including the nose plug 100, as well as a diving helmet 10 including the nose plug 100 and/or the NCD 20 that includes the nose plug 100, is contemplated and encompassed within the instant disclosure.
The nose plug 100 is configured to be arranged within a piece of diving equipment, such as a diving helmet 10, and is inaccessible by a diver's hand during a dive (i.e., while wearing the diving helmet 10). The nose plug 100 is connectable to a mating component (e.g., a nose clearing device 20, an adapter, a sealing device) of a piece of diving equipment (e.g., a diving helmet 10). The nose plug 100 is connectable to and/or a portion of a nose clearing device 20 (“NCD”) that is attachable to and positioned within a diving helmet 10 during use as generally illustrated in
As generally illustrated in
The base 110 and the nasal inserts 140, 140′ are integrally formed with and/or connected to one another (e.g., via molding) such that nose plug 100 is a monolithic component. Conceivably, the base 110 and the nasal inserts 140, 140′ may be separate and/or individual components that are connected to one another to, for example, enable the nasal inserts 140, 140′ to be detached and replaced (e.g., with a new nasal insert and/or a nasal insert of a different size).
The nose plug 100 and the portions, elements, and/or components thereof (e.g., the base 110, the nasal inserts 140, 140′, the deformable skirt 174) is composed of a skin safe and stretchable (e.g., elastically deformable) material. The material of the nose plug 100 is also non-porous (i.e., a non-porous material) and resistant to changes in size, shape, and/or density due to the forces present in an underwater and/or diving environment. In contrast, porous materials (e.g., foam) may compress, collapse, and/or shirk due to the increased forces and/or pressures present in underwater and/or diving environments (e.g., at greater depths). Non-porous materials are thus typically preferable to porous materials due to their ability to maintain their general size, shape, and density when subjected to the forces of the underwater and/or diving environment. The material of the nose plug 100 is also generally a soft rubber material to enhance user comfort. In other words, the nose plug 100 and the portions, elements, and/or components thereof (e.g., the base 110, the nasal inserts 140, 140′, the deformable skirt 174) is composed of a skin safe, elastically deformable (e.g., stretchable), non-porous, soft rubber material that is capable of withstanding the forces of an underwater and/or diving environment without significant impact and/or influence on its size, shape, and/or density, such as silicone, nitrile, latex, and/or other suitable material.
As generally illustrated in
The base 110 has and/or defines a “V” shape profile (see, e.g.,
As generally illustrated in

As generally illustrated in
The nasal inserts 140, 140′ are disposed on and project from an external surface (e.g., an upper surface 116) of the base 110. The first nasal insert 140 is disposed on and projects from the first angled region 118 of the upper surface 116 of the base 110. The second nasal insert 140′ is disposed on and projects from the second angled region 120 of the upper surface 116 of the base 110. The first nasal insert 140 and the second nasal insert 140′ are mirror images of one another relative to the centerline 112 of the base 110 and/or a Y-Z plane extending along the centerline 112, and are therefore structured and arranged in a substantially similar manner.
The first nasal insert 140 is disposed on and projects from the first angled region 118 of the upper surface 116 of the base 110. The first nasal insert 140 has a central longitudinal axis 142 that extends generally perpendicular to the first angled region 118 of the upper surface 116 of the base 110. Due to the angle of the first and second angled regions 118, 120, an angle of 10°-20° (preferably, 16°) is defined by and between the central longitudinal axis 142 of the first nasal insert 140 and the central longitudinal axis 142′ of the second nasal insert 140′. The first nasal insert 140 has a first/wide axial end that is disposed on, contacts, and/or is connected to the base 110. The first nasal insert 140 also has an opposite, second/narrow/free axial end that is disposed spaced apart from the base 110. One or more radial dimensions of the first nasal insert 140 (e.g., a radial dimension along the major axis 152 and/or a radial dimension along the minor axis 154) is greater at the first axial end than at the second axial end. An outer circumferential surface 144 of the first nasal insert 140 tapers radially inwardly toward the central axis 142 of the first nasal insert 140 as the outer circumferential surface 144 extends from the first axial end toward the second axial end of the first nasal insert 140. The outer circumferential surface 144 extends at an angle A2 of 5°-15° (preferably, 9°) relative to the central axis 142 of the first nasal insert 140 (see, e.g.,
The first nasal insert 140 includes (i) a frustoconical and/or truncated cone shaped portion 146 and (ii) a rounded and/or dome shaped portion 148. The frustoconical portion 146 is disposed on, contacts, and/or is connected to the base 110 (e.g., the first angled region 118 of the upper surface 116). The dome portion 148 is disposed at and/or connected to an end of the frustoconical portion 146 opposite the base 110. The rounded design of the dome portion 148 provides enhanced user comfort as there are fewer sharp edges and/or corners that can cause discomfort, particularly when touching, contacting, and/or pressing against the sensitive internal surface of the nose deep within the nostril. A height Hfp or longitudinal dimension of the frustoconical portion 146, which extends parallel to the central axis 142 of the first nasal insert 140 from the base 110 to the dome portion 148, is 0.40 to 0.60 inches (preferably, 0.52 inches). A height or longitudinal dimension of the dome portion 148 is 0.01 to 0.1 inches (preferably, 0.025 inches). A total height HT of the first nasal insert 140 (e.g., from the wide end of the frustoconical portion 146 to the tip of the dome portion 148) is 0.41 to 0.7 inches (preferably, 0.425 to 0.625 inches; more preferably, 0.545 inches). In some examples, the first nasal insert projects at least 0.1 inches (e.g., at least 0.2 inches; 0.25 to 0.5 inches) into the first nostril when the nose plug 100 is in use to ensure a large contact surface area is established between the first nasal insert 140 and the surfaces within and/or defining the first nostril and that an airtight seal is achieved. The aforementioned heights Hfp, HT allows the first nasal insert 140 to project far enough into the first nostril to prevent accidental removal from the first nostril and to form a tight seal of the first nostril during use, while also not projecting far enough into the first nostril to cause user discomfort. The outer circumferential surface 144 of the first nasal insert 140 is defined and/or formed entirely by the frustoconical portion 146, though this is not required.
As generally illustrated in
The ellipse shaped cross-section 150 has a major axis 152 and a minor axis 154. The major axis 152 extends diametrically across the ellipse 150 between the two vertices of the ellipse 150 that are disposed furthest from one another. The minor axis 154 extends diametrically across the ellipse 150 between the two vertices of the ellipse 150 that are disposed closest to one another. The major axis 152 and the minor axis 154 extend perpendicularly to one another. The first nasal insert 140 is arranged on the first angled region 118 of the upper surface 116 such that the major axis 152 extends at an angle A3 of 20°-30° (preferably, 25°) relative to the centerline 112. In other words, the angle A3 of 20°-30° (preferably, 25°) is defined between the major axis 152 and the centerline 112 of the base 110. The major axis 152 of the first nasal insert 140 and the major axis 152′ of the second nasal insert 140′ extend transversely relative to one another and intersect the centerline 112 on the same side of the base 110. The major axes 152, 152′ of the nasal inserts 140, 140′ intersect each other at a 40°-60° (preferably, 50°) angle A4. This arrangement enhances user comfort and facilitates effective sealing of the nostrils as the orientation of the nasal inserts 140, 140′ relative to one another corresponds to and/or mimics the typical natural orientation of the first and second nostrils relative to one another.
At the first end of the first nasal insert 140, a diameter Dmaj of the first nasal insert 140 along the major axis 152, which may be referred to as the major diameter Dmaj, is 0.5 to 0.8 inches and a diameter Dmin of the first nasal insert 140 along the minor axis 154, which may be referred to as the minor diameter Dmin, is 0.4 to 0.7 inches. The aforementioned diameters Dmaj, Dmin overlap, encompass, correspond to, and/or generally correspond to the dimensions of an average nostril and/or nostril opening. The diameters Dmaj, Dmin may also be slightly larger than the dimensions of an average nostril and/or nostril opening to ensure a snug fit of the first nasal insert 140 within the first nostril. This enables the first nasal insert 140 to sufficiently contact the surface(s) of the nose to seal the first nostril with a minimal amount of deformation and/or stretching of the user's nose. If the major and minor diameter Dmaj, Dmin of the first nasal insert 140 are too small, the first nasal insert 140 may be unable to sufficiently contact the surface(s) of the nose to completely block and/or seal the first nostril. If the major and minor diameter Dmaj, Dmin of the first nasal insert 140 are too large, the first nasal insert 140 may cause an unnecessarily large amount of deformation and/or stretching of the user's nose during use and cause discomfort.
A proximal point 156 of the first nasal insert 140 that is disposed closest to the centerline 112, a central vertical and/or Z-direction axis 114 of the base 110, and the central axis 142 of the first nasal insert 140 are aligned with one another in the X-direction. The first nasal insert 140 is disposed on the first angled region 118 a distance Doff of 0.1 to 0.2 inches (preferably, 0.12 to 0.17 inches) from the centerline 112 of the base 110 in the X-direction, which may also be referred to as an offset distance Doff. More specifically, the offset distance Doff is defined between the proximal point 156 of the first nasal insert 140 and the central vertical axis 113 of the base 110. This arrangement enhances user comfort and facilitates effective sealing of the nostrils as the relative arrangement of and distance between the nasal inserts 140, 140′ corresponds to and/or mimics the typical relative arrangement of and distance between the first and second nostrils.
The second nasal insert 140′ is disposed on and projects from the second angled region 120 of the upper surface 116 of the base 110. The first nasal insert 140 and the second nasal insert 140′ are mirror images of one another relative to the centerline 112 of the base 110 and/or a Y-Z plane extending along the centerline 112. As such, the second nasal insert 140′ is configured in a substantially similar manner as the previously described first nasal insert 140. The arrangement of the second nasal insert 140′ relative to the base 110, the centerline 112, and/or the second angled region 120 of the upper surface 116 is also substantially similar to the arrangement of the first nasal insert 140 relative to the base 110, the centerline 112, and/or the first angled region 118 of the upper surface 116. The second nasal insert 140′ includes central longitudinal axis 142′, an outer circumferential surface 144′, a frustoconical portion 146′, a dome portion 148′, a frustoconical portion height Hfp′, a total height HT′, an ellipse shaped cross-section 150′, a major axis 152′, a minor axis 154′, a proximal point 156′, an angle A2′, an angle A3′, a major diameter Dmaj′, a minor diameter Dmin′, and an offset distance Doff′ that are structured and arranged in a substantially similar manner as the corresponding portions of the first nasal insert 140. The portions, elements, and/or features of the second nasal insert 140′ are not described in further detail for brevity.
The size and/or dimensions of the nose plug 100 may be tailored based on the size of the intended user to provide optimal comfort and effectiveness. For example, the nose plug 100 may be provided in several different sizes such as a small, medium, and large size. The dimensions of the nasal inserts 140, 140′ of a size small nose plug 100 and a size medium nose plug 100 are approximately 80% and 90%, respectively, of the dimensions of a large size nose plug 100. For example, the nasal inserts 140, 140′ of a size large nose plug 100 have a major diameter Dmaj, Dmaj′ of 0.7 inches, a minor diameter Dmin, Dmin′ of 0.6 inches, an offset distance Doff, Doff′ of 0.16 inches, a frustoconical portion height Hfp, Hfp′ of 0.52 inches, a dome portion height of 0.025 inches, and/or a total height HT, HT′ of 0.545 inches. The nasal inserts 140, 140′ of a size medium nose plug 100 have a major diameter Dmaj, Dmaj′ of 0.63 inches, a minor diameter Dmin, Dmin′ of 0.54 inches, an offset distance Doff, Doff′ of 0.144 inches, a frustoconical portion height Hfp, Hfp′ of 0.468 inches, a dome portion height of 0.022 inches, and/or a total height HT, HT′ of 0.490 inches. The nasal inserts 140, 140′ of a size small nose plug 100 have a major diameter Dmaj, Dmaj′ of 0.56 inches, a minor diameter Dmin, Dmin′ of 0.48 inches, an offset distance Doff, Doff′ of 0.128 inches, a frustoconical portion height Hip, Hip′ of 0.416 inches, a dome portion height of 0.02 inches, and/or a total height HT, HT′ of 0.436 inches. The dimensions of the base 110 are the same regardless of the size (i.e., small, medium, large) of the nose plug 100.
Optionally, the nose plug 100 and/or the base 110 includes one or more attachment formations 170 via which the nose plug 100 is attachable to and/or mountable on an NCD 20. The nose plug 100 includes one or more attachment formations 170 at least when the nose plug 100 is configured as a nose plug attachment 102. The attachment formation 170 is configured to engage one or more portions of the NCD 20 to attach, connect, and/or mount the nose plug attachment 102 to the NCD 20. For example, the attachment formation 170 may engage the nose block 22 of an NCD 20 (see, e.g.,
The exemplary nose plug 100 depicted in
In other examples, the attachment formation 170 is configured to engage the mounting shaft 24 of an NCD 20 to attach the nose plug 100 to the NCD 20. In such examples, the attachment formation 170 includes and/or is defined by a recess and one or more mechanical fasteners. The recess is disposed in and defined by the base 110, and is configured to removably receive at least a portion (e.g., an end) of the mounting shaft 24. The mechanical fastener (e.g., an internal thread and/or detent projection) is attached to the base 110 and configured to releasably engage a complimentary fastener of the mounting shaft 24 to attach and/or connect the nose plug 100 to the mounting shaft 24.
While the disclosed nose plug 100 has been described with respect to its use in connection with underwater diving, the nose plug 100 is not limited to use in connection with underwater diving. The nose plug 100 may conceivably be utilized in connection with any type of equipment, activity, and/or situation that may involve plugging a nose and/or sealing a nasal passage. For example, the nose plug 100 may be utilized to prevent dangerous substances and/or chemicals from entering the nose and/or being inhaled, to prevent water from entering the nose (e.g., while swimming, water skiing, etc.), to avoid experiencing an undesirable smell, among many other possible uses.
