The term “hole” is used in this way to maintain clarity relative to the “first aperture,” “second aperture,” and “third aperture,” described herein. The term “head region,” as it is used throughout this disclosure, is defined as the area spanning from approximately an individual's neck to approximately the top of the individual's head.

[0022] Various aspects of the disclosure will now be described in detail, without limitation. In the following disclosure, protective apparatuses for minimizing risk, such as due to individuals' close physical proximity to one another, of transmission of COVID-19 and other viruses and infectious agents will be discussed.

[0023] Protective apparatuses of the present disclosure may be used in a number of different environments. Without limitation, protective apparatuses of the present disclosure may be installed upon a vacuum hose in a dentist's office. In such embodiment the protective apparatus may shield the dentist or other involved healthcare worker from the risk of transmission of infectious agents to them through aerosols emanating from a patient (whom the healthcare worker is treating) occupying an object such as a chair (and likewise may mitigate the risk of transmission of infectious agents to the patient as well). Such risk mitigation may be achieved, without limitation, by positioning a substantially transparent shield component of the protective apparatus between the head region of the patient and the head region of a healthcare worker treating the patient. This may be accomplished, without limitation, by installing the protective apparatus to a vacuum hose or other substantially cylindrical suctioning device and positioning the suctioning device so that the substantially transparent shield component is located between the head region of the patient and the head region of a healthcare worker treating the patient. Similarly, protective apparatuses enabled by this disclosure may be operatively attached to an articulating mechanical arm and the articulating arm may be manipulated so as to position the substantially transparent shield component of a protective apparatus enabled by this disclosure between the head region of a patient and the head region of a healthcare worker treating said patient so as to mitigate the risk of, for example, aerosolized droplets potentially containing infectious agents from projecting onto the healthcare worker from the patient or from projecting from the healthcare worker onto the patient.

[0024] Referring now to FIGS. 1-3 and 5, apparatuses enabled by this disclosure 100 will now be discussed in more detail. Apparatuses enabled by this disclosure may comprise, at one end, a receiving component 101 comprising a first aperture 200, 300. Said first aperture may be structured so as to accommodate an object having a substantially cylindrical shape including, without limitation, a vacuum hose 500. The first aperture may be sized so as to accommodate substantially cylindrical objects of varying diameters, including, without limitation, such objects having outside diameters of between approximately 2 inches and approximately 6 inches, more preferably objects having outside diameters of between approximately 3 inches and approximately 5 inches. The latter such sizing is particularly advantageous, without limitation, in that it renders such protective apparatuses substantially universal with regard to the breadth of suctioning devices to which they may be installed.

[0025] The receiving component 101 may be comprised of any number of light-weight materials including, without limitation, cardboard.

[0026] Referring now to FIGS. 2 and 3, the first aperture 200, 300 will now be discussed in greater detail. First apertures of the present disclosure may be substantially circular in shape. Such first apertures may comprise a series of flanges 202, 301 extending inward toward a central point inside the first aperture. The first aperture may comprise between approximately 15 and approximately 35 flanges, preferably between approximately 20 and approximately 30 flanges.

[0027] The first aperture of the receiving component, including the associated flanges, are intended to accommodate placement of a substantially cylindrical object through the first aperture and flanges. The friction generated by insertion of a substantially cylindrical object having an outer diameter of between approximately two inches and approximately six inches, preferably between approximately three inches and approximately five inches, serves as means for holding the substantially cylindrical object securely in place.

[0028] Each flange may also comprise a round hole 302 located approximately near the end of the flange located approximately at the outer perimeter of the first aperture. These round holes help prevent tearing at or near the base of the flanges by decreasing the physical stress associated with insertion of an object through the first aperture and flanges. The first aperture, including the associated flanges, may be located at an approximately central location on the receiving component so as to contribute to substantially stable positioning of the receiving component around a substantially cylindrical object 500 upon insertion of such object through the first aperture.

[0029] The portion of the receiving component comprising the first aperture and associated flanges as described herein may further include a tab 103 that protrudes from said portion. Such protruding tab facilitates handling of the protective apparatuses enabled by this disclosure.

[0030] A string 203 or similar restraining means such as a rope, cord, zip-tie, or thread may be used to further secure the substantially cylindrical object and hold it substantially stationary upon insertion thereof through the first aperture and flanges. According to such an embodiment, the receiving component may further comprise, on its outer surface, second and third apertures 204 through which the string or similar restraining means may be inserted as supplemental securing means for holding the substantially cylindrical object substantially stationary. According to such an embodiment, these two apertures may be approximately 0.13 and 0.38 inches in diameter each.

[0031] As depicted in FIG. 2, a first and second end of the string or other restraining means may be pulled through the second and third apertures, respectively, so that said string or other restraining means extends to the interior of the receiving component through which the substantially cylindrical object will extend upon insertion. By so positioning the string or other restraining means, said string or other restraining means may be wrapped around a suctioning device or other object that has been inserted through the first aperture, thus providing for additional stability for said object. These second and third apertures may be positioned so that they are between approximately one inch apart and approximately two inches apart, without limitation.

[0032] Referring now to FIGS. 1, 2, and 4, the substantially transparent shield component, 102, 201, 400 will be discussed in greater detail. The substantially transparent shield component may be comprised of any number of materials suitable for serving as a substantially impermeable protective barrier. The substantially transparent shield component may be comprised of any solid material that is both substantially impermeable and substantially transparent such as, without limitation, certain types of plastic or clear glass. The plastics that may be suitable for use in making the shield component may comprise, without limitation, polyethylene terephthalate glycol (or PETG), polymethyl methacrylate, cellulose acetate butyrate, or polycarbonate.

[0033] Preferably, the shield component may be comprised of a light-weight material to facilitate easy handling thereof. In one embodiment, the shield component may be constructed using materials that are not toxic to human beings. Said material may be approximately 1.5 millimeters to approximately 6 millimeters in thickness, without limitation. More preferably, said material may be approximately 2 millimeters to approximately 5 millimeters in thickness, without limitation.

[0034] The substantially transparent shield component of the protective apparatuses enabled by this disclosure may be between approximately six inches and approximately 22 inches in length, without limitation. More preferably, the substantially transparent shield component may be between approximately nine inches and approximately 18 inches in length, without limitation.

[0035] The substantially transparent shield component of the protective apparatuses of the present disclosure may have any number of contours. The substantially transparent shield component may slope upward on the left-hand side and the right-hand side thereby comprising a concave shape. The substantially transparent shield component may comprise protrusions to accommodate the curvature of an individual's face.

[0036] The substantially transparent shield component of the protective apparatuses enabled by the present disclosure may be detachable from the receiving component and may be replaceable. Alternatively, the substantially shield component and the receiving component may comprise a single unit.

[0037] By way of illustration only, protective apparatuses enabled by the present disclosure may be constructed using flat stock material that may comprise glue or similar adhesive on one side. Such material may be folded into a three-dimensional structure that is self-supporting. Protective apparatus enabled by the present disclosure may be supplied in a knock-down kit. Such flat stock material and knock-down kit assembly helps to reduce manufacturing costs, reduce shipping costs, reduce the required storage space, and increase the ease of disposal.

[0038] Protective apparatus enabled by the present disclosure may be installable to a vacuum hose or other suctioning device substantially cylindrical in shape. In such embodiment, said suctioning device may produce a negative air pressure thereby removing air from the space immediately underneath the substantially transparent shield component. In such embodiment, the negative air pressure generated by the suctioning device may remove and facilitate removal of infectious agents present immediately underneath the substantially transparent shield component and/or attached to the downward-facing surface of the substantially transparent shield component.

[0039] In another embodiment, protective apparatuses enabled by the present disclosure may be operatively attached to an articulating mechanical arm. Said articulating arm may be located and manipulated so that the substantially transparent shield component of the protective apparatus is positioned overtop of the head region of an individual so as to minimize the risk of droplets of saliva potentially containing infectious agents, and/or of airborne infectious agents, projecting from the individual onto others in the vicinity of the individual, and from reaching the individual if exuded from others in the individual's vicinity.

[0040] Systems for mitigating the risk of transmission of an infectious disease as contemplated by this disclosure may, without limitation, comprise protective apparatuses as described herein installed upon a suctioning device comprising a substantially cylindrical vacuum hose. Those of skill in the art will recognize that additional components may, optionally, be added to said system. Such additional components may comprise, without limitation, a chamber component comprising means for disinfecting air entering the suctioning device discussed herein. Such disinfecting means may comprise, without limitation diodes emitting ultraviolet light.

[0041] In another embodiment, systems enabled by this disclosure may comprise a protective apparatus enabled by this disclosure operatively attached to an articulating mechanical arm. Such a system may, optionally, further comprise a suctioning device for removing infectious agents from the downward-facing surface of the substantially transparent shield component of the protective apparatus and from the area underneath said downward-facing surface but above an individual over whom the substantially transparent shield component has been positioned.

[0042] Protective apparatuses enabled by the present disclosure, as well as associated systems as described herein, may be used, without limitation, in a dentist's office to minimize the risk of transmission of an infectious disease between, for example, patient and dentist, or between patient and dental assistant or other individual present near the work area where the dental patient is being treated. Those of skill in the art will readily recognize that protective apparatuses and associated systems enabled by the present disclosure may be used to mitigate the risk of transmission of an infectious disease between patient and healthcare worker in clinical settings other than dentists' offices as well such as, for example, in a hospital setting or any other clinical setting where patient and healthcare worker are in close physical proximity to one another.

[0043] The protective apparatuses and associated systems contemplated by this disclosure may be used in connection with methods for mitigating the risk of transmission of an infectious disease by mitigating the risk of potential exposure to droplets comprising infectious agents and/or to airborne infectious agents. Such methods, may comprise, without limitation, installing the receiving component of the protective apparatuses described herein to a substantially cylindrical suctioning device; locating the suctioning device such that the substantially transparent shield component of the protective apparatus extending therefrom is positioned between the head region of a healthcare worker and the head region of a patient whom the healthcare worker is treating; and actuating the suctioning device so that it exerts a negative air pressure toward a downward-facing surface of the substantially transparent shield component and the space below said surface. Those of skill in the art will readily appreciate the sorts of actuating means, such as, without limitation, physically manipulable control components, that are commonly incorporated into suctioning devices such as suctioning devices commonly employed in a dentist's offices, without limitation.

[0044] Alternatively, methods enabled by the present disclosure may comprise protective apparatuses as described herein operatively attached to an articulating mechanical arm, with and without an associated suctioning device. According to such methods, the protective apparatus may be attached to the mechanical arm; and the mechanical arm may be manipulated such that the substantially transparent shield component of the protective apparatus extending therefrom is positioned between, for example, the head region of a healthcare worker and the head region of a patient whom the healthcare worker is treating. Such methods may further comprise locating a suctioning device such that said device may remove infectious agents present immediately underneath the substantially transparent shield component and/or attached to the downward-facing surface of the substantially transparent shield component.

[0045] While various aspects of the protective apparatuses enabled by this disclosure, as well as associated systems and methods for mitigating the risk of transmission of an infectious disease, have been described above, the description of this disclosure is intended to illustrate and not limit the scope of the invention. The invention is defined by the scope of the claims and not the illustrations and examples provided in the above disclosure. Skilled artisans will appreciate additional aspects of the protective apparatuses, and the associated systems and methods, enabled by this disclosure, which may be realized in alternative embodiments, after having the benefit of the above disclosure. Other aspects, advantages, embodiments, and modifications are within the scope of the claims.
