  • Presently, the focus is on healthcare workers wearing personal protective equipment (PPE) 10, such as shown in FIG. 1. For example, gloves 11, masks 12, and shields 13 are worn to prevent the spread of an infectious disease from patients to healthcare providers. However, the supplies for PPE 10 can be limited, especially during a pandemic.
  • FIG. 2 illustrates an implementation of an example respiratory isolation enclosure for patients (“respiratory enclosure”) 100 according to the present disclosure. As shown in FIG. 2, in some implementations, the respiratory enclosure 100 comprises a side surface 110 and an upper or top surface 120. In some implementations, the respiratory enclosure 100 may further comprise a lower or bottom surface.
  • As shown in FIG. 2, in some implementations, the respiratory enclosure 100 also comprises one or more access openings 140 and one or more ventilation openings 150. In some implementations, the respiratory enclosure 100 may further comprise any other suitable components.
  • As shown in FIG. 2, in some implementations, the side surface 110 extends from the upper surface 120 to the floor or similar surface, e.g. when the respiratory enclosure 100 is used. For example, in some implementations, the side surface 110 extends from the edge or perimeter of the upper surface 120.
  • In some implementations, the side surface 110 may extend from the upper surface 120 to a lower surface of the respiratory enclosure 100.
  • In some implementations, the side surface 110 extends generally vertical from the upper surface 120, e.g. when the respiratory enclosure 100 is used.
  • In some implementations, the side surface 110 extends from the upper surface 120 to the floor, e.g. when the respiratory enclosure 100 is used, such that the side surface 110 encircles the interior of the respiratory enclosure 100.
  • In some implementations, the side surface 110 may comprise a continuous surface that encircles the interior of the respiratory enclosure 100, e.g. when the respiratory enclosure 100 is used. In some implementations, the side surface 110 may comprise two or more surfaces that encircle the interior of the respiratory enclosure 100.
  • For example, as shown in FIG. 2, in some implementations, the side surface 110 may comprise two sets of generally opposite facing surfaces. In some implementations, the surfaces are attached and extend to encircle the interior of the respiratory enclosure 100 as a generally rectangular shaped side surface 110.
  • In some implementations, the side surface 110 may comprise any other suitable configuration of surfaces. In some implementations, the side surface 110 may encircle the interior of the respiratory enclosure 100 in any other suitable shape, e.g. when the respiratory enclosure 100 is used.
  • In some implementations, the side surface 110 may be weighted or otherwise suitably configured to keep the side surface 100 in place or position extending to the floor or similar surface, e.g. when the respiratory enclosure 100 is used. For example, in some implementations, the side surface 110 may comprise one or more weights or other suitable components. In some implementations, the weights or other suitable components are positioned at or adjacent to the lower or bottom edge of the side surface 110, which may position at or adjacent to the floor when the respiratory enclosure 100 is used.
  • In some implementations, the weights or other suitable components may have any suitable size, shape, or other configuration.
  • In some implementations, the side surface 110 may be weighted or otherwise suitably configured, such as by the above described weights or other suitable components, such that the side surface 110 at least generally encloses and/or seals the interior of the respiratory enclosure 100 at the floor or similar surface when the respiratory enclosure 100 is used.
  • In some implementations, the side surface 110 may be weighted or otherwise suitably configured such that the side surface 110 is at least generally kept in place or position extending from the upper surface 120 to the floor or other suitable surface when the respiratory enclosure 100 is used.
  • In some implementations, the upper surface 120 extends from the upper or top edge of the side surface 110. In some implementations, the upper surface 120 extends generally horizontal from the side surface 110, e.g. when the respiratory enclosure 100 is used.
  • In some implementations, the upper surface 120 extends from the side surface 110, e.g. when the respiratory enclosure 100 is used, such that the upper surface 120 covers or encloses above the interior of the respiratory enclosure 100.
  • In some implementations, the upper surface 120 may comprise a continuous surface that covers or encloses above the interior of the respiratory enclosure 100, e.g. when the respiratory enclosure 100 is used. In some implementations, the upper surface 120 may comprise two or more surfaces that cover or enclose above the interior of the respiratory enclosure 100.
  • For example, as shown in FIG. 2, in some implementations, the upper surface 120 may comprise two sets of generally opposite facing surfaces. In some implementations, the surfaces are attached and extend to cover or enclose above the interior of the respiratory enclosure 100 as a generally vaulted or domed shaped upper surface 120.
  • In some implementations, the upper surface 120 may comprise any other suitable configuration of surfaces. In some implementations, the upper surface 120 may cover or enclose above the interior of the respiratory enclosure 100 in any other suitable shape, e.g. when the respiratory enclosure 100 is used.
  • As shown in FIG. 2, in some implementations, the respiratory enclosure 100 comprises one or more access openings 140. In some implementations, the access openings 140 may be any suitable shape. In some implementations, the access openings 140 may be any suitable size.
  • In some implementations, the access openings 140 may be positioned at any suitable location of the respiratory enclosure 100. For example, as shown in FIG. 2, in some implementations, one or more of the access openings 140 may be positioned on the side surface 110.
  • In some implementations, the access openings 140 may have any other suitable configuration. In some implementations, the access openings 140 may have any other suitable feature.
  • In some implementations, the access openings 140 are configured to be openable. In some implementations, the access openings 140 are configured to be sealable or resealable
  • In some implementations, the access openings 140 are configured to allow access to a patient positioned in the respiratory enclosure 100. For example, in some implementations, the access openings 140 are configured to allow a healthcare worker or provider to access a patient in the respiratory enclosure 100.
  • In some implementations, the access openings 140 may be configured to allow access into the respiratory enclosure 100 for any other suitable purpose.
  • In some implementations, the access openings 140 are configured to allow equipment to be connected to a patient positioned in the respiratory enclosure 100. For example, in some implementations, the access openings 140 are configured to allow equipment positioned outside of the respiratory enclosure 100 to be connected to a patient in the respiratory enclosure 100.
  • In some implementations, the connected equipment may include a ventilator. In some implementations, the connected equipment may include monitoring equipment. In some implementations, the connected equipment may include any other suitable equipment.
  • As shown in FIG. 2, in some implementations, the respiratory enclosure 100 comprises one or more ventilation openings 150. In some implementations, the ventilation openings 150 may be any suitable shape. In some implementations, the ventilation openings 150 may be any suitable size.
  • In some implementations, the ventilation openings 150 may be positioned at any suitable location of the respiratory enclosure 100. For example, as shown in FIG. 2, in some implementations, one or more of the ventilation openings 150 may be positioned on the upper surface 120.
  • In some implementations, the ventilation openings 150 may have any other suitable configuration. In some implementations, the ventilation openings 150 may have any other suitable feature.
  • In some implementations, the ventilation openings 150 are configured to be openable. In some implementations, the ventilation openings 150 are configured to be sealable or resealable
  • In some implementations, the ventilation openings 150 are configured to allow ventilation, such as air, into the respiratory enclosure 100. In some implementations, the ventilation openings 150 are configured to allow ventilation out of the respiratory enclosure 100.
  • For example, in some implementations, one or more of the ventilation openings 150 may be configured to connect to an external ventilation system, such as a ventilation system of the building, room, etc. in which the respiratory enclosure 100 is used. In some implementations, the ventilation system may be a portable ventilation system positioned adjacent to the respiratory enclosure 100.
  • In some implementations, one or more of the ventilation openings 150 may be configured to connect to any other suitable ventilation components, such as to a high-efficiency particulate air (HEPA) filter used to filter output and/or input air from the respiratory enclosure 100 for infection or disease spread control.
  • As described more below, in some implementations, the ventilation openings 150 may be configured to connect to a ventilation system to provide a negative air pressure environment in the respiratory enclosure 100.
  • In some implementations, the respiratory enclosure 100 may be any suitable shape. For example, as shown in FIG. 2, in some implementations, the respiratory enclosure 100 may be generally rectangular prism shaped.
  • In some implementations, the respiratory enclosure 100 may be any suitable size. For example, as shown in FIG. 3, in some implementations, the respiratory enclosure 100 is sized to house a patient. In some implementations, the respiratory enclosure 100 is sized to house a patient including the patient's bed, such as a hospital bed.
  • In some implementations, the respiratory enclosure 100 is an individual sized enclosure. For example, in some implementations, the respiratory enclosure 100 is smaller than the size of a room, such as a patient's room at a hospital or other care facility. In some implementations, the respiratory enclosure 100 is appropriately sized to house one patient and one bed that is inside a room.
  • In some implementations, the respiratory enclosure 100 is transparent. For example, in some implementations, the respiratory enclosure 100 is configured such that a patient positioned in the respiratory enclosure 100 can be seen from outside of the respiratory enclosure 100, such as through the side surface 110. In this way, in some implementations, a patient can see and be seen by various persons, including family and/or friend visitors, to help minimize the impact of isolation from others.
  • In some implementations, the respiratory enclosure 100 may be semi-transparent. In some implementations, the respiratory enclosure 100 may be translucent. In some implementations, the respiratory enclosure 100 may be opaque. In some implementations, the respiratory enclosure 100 may be partly transparent, semi-transparent, translucent, and/ or opaque. In some implementations, the respiratory enclosure 100 may have any other suitable visibility feature.
  • In some implementations, the respiratory enclosure 100 is configured to respiratorily (or respirationally) isolate a patient with an infectious disease, such as COVID-19, to prevent the spread of the disease to healthcare providers or workers, such as doctors, nurses, and ancillary staff.
  • In some implementations, the respiratory enclosure 100 is configured to help prevent the spread of an infectious disease from a patient to healthcare providers.
  • In some implementations, the respiratory enclosure 100 is configured to reduce the spread of an infectious disease from a patient to healthcare providers.
  • In some implementations, the respiratory enclosure 100 is configured to respiratorily isolate a patient while allowing the patient to see and be seen through the respiratory enclosure 100 by various persons, including family and/or friend visitors, to help minimize the impact of isolation from others while in the respiratory enclosure 100.
  • In some implementations, the respiratory enclosure 100 is configured to maintain a negative pressure or negative air pressure environment in the respiratory enclosure 100 to prevent the spread of an infectious disease from a patient to healthcare providers. For example, FIG. 4 illustrates an example diagram representation of the negative air pressure maintained within the respiratory enclosure 100.
  • In some implementations, the respiratory enclosure 100 is configured to maintain a negative air pressure by maintaining a lower air pressure within the respiratory enclosure 100 than the air pressure outside of the respiratory enclosure 100, such as in the room or other location in which the respiratory enclosure 100 is positioned. In some implementations, the respiratory enclosure 100 is configured to maintain the negative air pressure by allowing more air to exit or output from the respiratory enclosure 100 than air to enter or input into the respiratory enclosure 100.
  • For example, as shown in FIG. 4, in some implementations, a sufficient amount of air, e.g. for a patient's ventilation and comfort, is allowed to input (e.g., passively) into the respiratory enclosure 100, such as through one or more of the ventilation openings 150 or other openings formed by the respiratory enclosure 100. In some implementations, a larger amount of air is allowed to output, e.g. actively suctioned or pumped, from the respiratory enclosure 100 than is allowed to input into the respiratory enclosure 100.
  • Thereby, in some implementations, the respiratory enclosure 100 maintains a negative air pressure environment in the respiratory enclosure 100, which prevents the spread of an infectious disease from a patient in the respiratory enclosure 100 to healthcare providers or other persons outside of the respiratory enclosure 100.
  • In some implementations, the output and/ or input of air to the respiratory enclosure 100 to maintain the negative air pressure is from a ventilation system connected to one or more of the ventilation openings 150, such as described above for FIG. 2.
  • In some implementations, the air outputted from the respiratory enclosure 100 to maintain the negative air pressure is output through a connected filter, such as a high-efficiency particulate air (HEPA) filter, to prevent the spread of an infectious disease from a patient in the respiratory enclosure 100 to healthcare providers or other persons outside of the respiratory enclosure 100.
  • In some implementations, the respiratory enclosure 100 is configured to allow access to a patient positioned in the respiratory enclosure 100, such as through one or more of the access openings 140.
  • In some implementations, the respiratory enclosure 100 is configured to allow equipment to be connected to a patient positioned in the respiratory enclosure 100, such as through one or more of the access openings 140.
  • In some implementations, the respiratory enclosure 100 is configured to allow ventilation, such as air, into and/or out of the respiratory enclosure 100, such as through one or more of the ventilation openings 150.
  • In some implementations, the respiratory enclosure 100 is configured to connect to an external ventilation system, such as a ventilation system of the building, room, etc. in which the respiratory enclosure 100 is used, such as by one or more of the ventilation openings 150.
  • In some implementations, the respiratory enclosure 100 is configured to connect to any other suitable ventilation components, such as to a high-efficiency particulate air (HEPA) filter for infection or disease spread control, such as through one or more of the ventilation openings 150.
  • In some implementations, the respiratory enclosure 100 may be configured to be a self supporting enclosure. For example, in some implementations, the respiratory enclosure 100 may comprise framing and/or supports for the side surface 110 and/or the upper surface 120.
  • In some implementations, the framing and/or supports may comprise any other suitable components, features, and/or configurations. In some implementations, the framing and/or supports may be integrated to the respiratory enclosure 100, such as to the side surface 110 and/or the upper surface 120.
  • In some implementations, the respiratory enclosure 100 may be configured to be a separately supported enclosure. For example, in some implementations, the respiratory enclosure 100 may be configured to be supported by framing and/or supports that are separate from the respiratory enclosure 100. In some implementations, the framing and/or supports may comprise any other suitable components, features, and/or configurations.
  • In some implementations, the respiratory enclosure 100 may be configured to be supported for use of the respiratory enclosure 100 in any other suitable way. For example, in some implementations, the side surface 110 and/or the upper surface 120 may be sufficiently rigid to support the respiratory enclosure 100 for use.
  • FIG. 5 illustrates another implementation of an example respiratory isolation enclosure for patients 200 according to the present disclosure. In some implementations, the respiratory enclosure 200 is generally the same or similar to the respiratory enclosure 100 described above for FIG. 2, such as indicated by like-numbered components in the figures.
  • For example, as shown in FIG. 5, in some implementations, the respiratory enclosure 200 comprises a side surface 210, an upper or top surface 220, and one or more access openings 240 and/ or ventilation openings 250 that are generally the same or similar respectively to the above-described side surface 110, upper or top surface 120, one or more access openings 140, and one or more ventilation openings 150 of the respiratory enclosure 100 of FIG. 2.
  • In some implementations, the side surface 210 may comprise a transparent polymer material. In some implementations, the transparent polymer material may be coated with an anti-viral substance or material.
  • In some implementations, the side surface 210 may comprise any other suitable material.
  • As shown in FIG. 5, in some implementations, the respiratory enclosure 200 may further comprise a skirt or skirt portion 230. In some implementations, the skirt portion 230 may extend from the side surface 210.
  • In some implementations, the skirt portion 230 may comprise a non transparent (e.g., translucent or opaque) polymer material. In some implementations, the skirt portion 230 may comprise a breathable material that is further configured to contain a virus or other respiratory contaminants within the respiratory enclosure 200.
  • In some implementations, the skirt portion 230 may comprise a woven or a non-woven material. In some implementations, the material may be the same or similar to the material of a surgical mask or an N95 mask.
  • In some implementations, the skirt portion 230 may comprise any other suitable material.
  • As described above for the respiratory enclosure 100 of FIG. 2, in some implementations, the one or more access openings 240 and/or ventilation openings 250 may be sealable and resealable. For example, in some implementations, the openings 240, 250 may comprise flaps (such as shown in FIGS. 12 and 14) configured to seal and reseal the openings 240, 250.
  • In some implementations, the flaps may be attached to hang down and seal the openings 240, 250. In some implementations, the flaps may be attached in any other suitable configuration to seal the openings 240, 250.
  • In some implementations, the flaps may be attached to the openings 240, 250 on the interior of the respiratory enclosure 200. In some implementations, the flaps may be attached to the openings 240, 250 on the exterior of the respiratory enclosure 200.
  • In some implementations, the flaps may be configured to unseal and allow access to the openings 240, 250, such as when a healthcare provider's hand or a part of an equipment is inserted through the opening 240, 250. In some implementations, the flaps may be configured to seal or reseal off access to the openings 240, 250, such as when a healthcare provider's hand or a part of an equipment is removed from the opening 240, 250.
  • As shown in FIG. 5, in some implementations, the respiratory enclosure 200 may further comprise a support 260 that is generally the same or similar to the above-described framing and/or supports of the respiratory enclosure 100 of FIG. 2.
  • In some implementations, the support 260 may comprise one or more components configured to position and support the respiratory enclosure 200 for use to enclose a patient. For example, as shown in FIG. 5, in some implementations, the support 260 may comprise a base 261, a vertical member 262, a horizontal member 263, and one or more hangers 264.
  • In some implementations, the support 260 is configured to position on a floor or other suitable surface, for example by the base 261. In some implementations, the support 260 is configured to attach to and/or support the side surface 110 and/or upper surface 120 of the respiratory enclosure 200, for example by the hangers 264.
  • In some implementations, the support 260 is configured to extend from the base 261 to the hangers 264, for example by the vertical member 262 and the horizontal member 263.
  • In some implementations, the support 260 may comprise one or more of any other suitable components configured to position and support the respiratory enclosure 200 for use to enclose a patient.
