[0148]
[0185] Certain examples of the present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, examples of the disclosure are shown. Indeed, these disclosures may be embodied in many different forms and should not be construed as limited to the examples set forth herein. Rather, these examples are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like parts throughout.
[0149]
[0186] Phrases such as "in one example," "according to one example," and "in some examples" generally mean that the particular feature, structure, or characteristic that follows the phrase may be included in at least one example of the present disclosure, and may be included in more than one example of the present disclosure (importantly, such phrases do not necessarily refer to the same example).
[0150]
[0187] When the specification states that a component or feature "may," "can," "could," "should," "would," "preferably," "in some cases," "typically," "optionally," "for example," "for example," "in some instances," "often," or "might" (or other such language) that the particular component or feature is not required to be included or to have that characteristic. Such component or feature may be optionally included in some examples, or it may be excluded.
[0151]
[0188] The words "example" or "exemplary" are used herein to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations.
[0152]
[0189] Sampling and capturing biological aerosol particles can be an important topic in both research and commercial activities. This can include detecting infectious diseases in sampled aerosols to accurately and quickly detect infectious diseases. Many (if not all) upper respiratory tract diseases result in some of the disease-causing pathogens being present in the aerosols exhaled by a patient while they are infected with the infectious disease. Examples of pathogenic particles include, but are not limited to, bacteria, viruses, and mold / fungal spores.
[0153]
[0190] However, many aerosol samplers are not applicable to direct sampling of exhaled breath. For example, many aerosol samplers may require, among other items, large pressure drops, pumps, and electrostatic fields, which may inhibit the patient's free breathing or otherwise dilute the exhaled aerosol with large amounts of ambient air. Additionally, the processes associated with these aerosol samplers tend to damage pathogens in the aerosol, which may adversely affect the ability to detect collected pathogens.
[0154]
[0191] According to various embodiments of the present disclosure, an aerosol collection device for capturing pathogen particles from exhaled aerosols is provided. In some embodiments, the aerosol collection device can include one or more sealed capsule components capable of storing a solution (including, but not limited to, a buffer solution). For example, the sealed capsule components can store a buffer solution in the form of an aqueous solution that can resist pH changes when an acid or base (e.g., from a sample) is added to the buffer solution. For example, the buffer solution can include a mixture of a weak acid and its conjugate base, or vice versa. In some embodiments, the buffer solution can provide a medium for storing the bioaerosol.
[0155]
[0192] In some embodiments, the buffer may contain positive and negative control molecules (including, but not limited to, positive and negative control proteins). In some embodiments, the positive and negative control molecules may be selected based on the needs of the subsequent diagnosis.
[0156]
[0193] It is noted that while the description herein uses buffer solutions as examples of solutions, the scope of the present disclosure is not limited to buffer solutions. In some instances, various embodiments of the present disclosure may use other types of solutions in addition to or instead of buffer solutions.
[0157]
[0194] In some embodiments, the aerosol collection device can feature a series of mechanical features to enhance the fidelity of sample capture. In some embodiments, the aerosol collection device can implement an immersed bubbler mechanism that includes a flow channel that guides exhaled breath into a buffer solution that is absorbed by a filter component to collect aerosols from the exhaled breath, where one or more bubbles form in the buffer solution and the aerosols from the exhaled breath are captured by the filter component and / or the buffer solution, details of which are described herein.
[0158]
[0195] As such, the exemplary aerosol collection device according to exemplary embodiments of the present disclosure can address various technical challenges associated with many aerosol samplers and sampling methods and provide accurate and rapid subsequent detection of infectious diseases from a sample (e.g., exhaled breath, etc.). For example, the exemplary aerosol collection device can provide an effective means for capturing aerosols within a sample, which can then be provided for downstream diagnostics for pathogen detection. Additionally or alternatively, the exemplary aerosol collection device can provide low pressure drop for user comfort, eliminating the need for a pump.
[0159]
[0196] 1A, 1B, and 1C, an exemplary aerosol collection device 100 is illustrated in accordance with an exemplary embodiment of the present disclosure.
[0160]
[0197] 1A, there is shown an exemplary diagram of an exemplary aerosol collection device 100. In the example shown in FIG. 1A, the exemplary aerosol collection device 100 can include a sample transfer adapter 115 and a device body portion 126 (including an upper plunger component 107).
[0161]
[0198] In some embodiments, the sample transfer adapter 115 can be in the form of a tubular structure that can provide a sampling tunnel. For example, the sample transfer adapter 115 can include a hollow portion in the center that allows air to pass through. In some embodiments, the sample transfer adapter 115 can be embodied as, but not limited to, a breathing straw. Additional embodiments of the sample transfer adapter 115 are described herein. A sample (e.g., exhaled breath from a user) can be administered into the exemplary aerosol collection device 100 through the sample transfer adapter 115. In some embodiments, the sample can include air and aerosols (which may contain pathogenic particles).
[0162]
[0199] While the above description provides examples of sample transfer adapter 115, it is noted that the scope of the present disclosure is not limited to the above description. In some examples, sample transfer adapter 115 may be embodied as, but not limited to, a mask and / or other device. Additional details of exemplary embodiments are shown and described herein, including, but not limited to, those described in connection with at least Figures 8 through 14B.
[0163]
[0200] In some embodiments, the sample transfer adapter 115 may be attached to the upper plunger component 107 and / or the device body 126 via various means, including, but not limited to, mechanical means (e.g., the sample transfer adapter 115 may be threaded into the device body 126) and / or chemical means (e.g., chemical glue, etc.).
[0164]
[0201] Referring now to FIG. 1B, a portion of an exemplary cross-sectional view of an exemplary aerosol collection device 100 is shown.
[0165]
[0202] 1B, the upper plunger component 107 can define an orifice 111 positioned along a central axis of the upper plunger component 107. In some embodiments, the orifice 111 can allow a sample (such as, but not limited to, exhaled breath from a user) to enter the exemplary aerosol collection device 100. For example, a user can blow into the sample transfer adapter 115, and the exhaled breath (also referred to as a sample) can pass through the sample transfer adapter 115 and the orifice 111 and be accepted by the exemplary aerosol collection device 100.
[0166]
[0203] In some embodiments, the sample can pass down central passage 117A, which is connected to central passage 117B and connected to the bottom portion of exemplary aerosol collection device 100. In some embodiments, central passage 117A and central passage 117B define at least a portion of a flow channel, details of which are described herein. In some embodiments, exemplary aerosol collection device 100 can include a valve component 118 disposed along central passage 117B. Valve component 118 can prevent sample from being extracted from exemplary aerosol collection device 100 through central passage 117A and central passage 117B. For example, if a user accidentally draws air from exemplary aerosol collection device 100 through sample transfer adapter 115, valve component 118 can prevent the user from drawing buffer solution from exemplary aerosol collection device 100, details of which are described herein.
[0167]
[0204] 1B, after passing through valve component 118, the sample may then be deposited into an opening 119 at the bottom portion of exemplary aerosol collection device 100. In some embodiments, opening 119 may be defined as the radial gap between sample distribution ring member 127 and the exterior of valve support ring member 128, details of which are described herein.
[0168]
[0205] In some embodiments, the exemplary aerosol collection device 100 can include one or more capsule components 102 positioned adjacent to a filter component 105. In some embodiments, the one or more capsule components 102 can be sealed. In some embodiments, the one or more capsule components 102 can store a buffer solution 103 containing positive and / or negative control molecules based on the target pathogen particles to be detected, allowing subsequent virus detection schemes to be more accurate. For example, if target pathogen particles are present, the positive and negative control molecules can allow for more accurate quantification of the target pathogen particles. In some embodiments, the positive and negative control molecules can provide an internal standard that can be detected by downstream diagnostics, which provides a better assessment of any unknown concentration of the targeted pathogen.
[0169]
[0206] In some embodiments, the capsule component 102 can be positioned within the container component 106 of the exemplary aerosol collection device 100 such that the capsule component 102 cannot be moved radially or circumferentially, but can only be moved vertically downward into the capsule extraction body 104. In some embodiments, the capsule component 102 can be mechanically positioned above the capsule extraction body 104. In the example shown in FIG. 1B , the capsule extraction body 104 can be in the form of or include a protrusion from the bottom surface of the exemplary aerosol collection device 100. As such, the capsule extraction body 104 can be configured, for example, to break a seal and allow the buffer solution 103 to be absorbed by the filter component 105. In some embodiments, the buffer solution 103 is contained on at least one of a first side (e.g., upstream side) of the filter element 105 adjacent to the sample distribution ring member 127 and / or a second side (e.g., downstream side) of the filter element 105 opposite the first side.
[0170]
[0207] 1B , the upper plunger component 107 can contain an O-ring 108, which can seal the upper plunger component 107 inside the exemplary aerosol collection device 100. The upper plunger component 107 can include a series of leg portions 109, which engage the capsule components 102. When the sample transfer adapter 115 is connected to the device body 126, a vertical force is exerted by the sample transfer adapter 115 on the top surface of the upper plunger component 107, and the force is transmitted to the one or more capsule components 102 (e.g., through the leg portions 109 of the upper plunger component 107), causing the capsule extraction body 104 to puncture the one or more capsule components 102 and break the seals of the capsule components 102, releasing the buffer solution 103 into the filter component 105. In some embodiments, in addition to being absorbed by the filter component 105, the buffer solution may also fill the interior volume below the valve component 118. In some embodiments, the buffer solution may additionally fill a lower portion of the breath analyzer chamber 121. As such, various embodiments of the present disclosure provide methodologies for ensuring proper usage of the exemplary aerosol collection device 100.
[0171]
[0208] In some embodiments, the buffer solution 103 can wet the filter element 105, and aerosols from the sample can be captured in the buffer solution 103 and / or the wetted filter element 105 when the filter element 105 is wetted by the buffer solution 103. In some embodiments, the wetted filter element 105 can capture pathogen aerosols from exhaled breath. For example, when an aerosol contacts the buffer solution 103, pathogen particles present in the aerosol can enter the buffer solution liquid medium, thus improving the capture efficiency of the aerosol from the sample. In the present disclosure, the buffer solution liquid medium containing the aerosols (such as, but not limited to, pathogen particles) can also be referred to as the sample liquid.
[0172]
[0209] In some embodiments, multiple holes (e.g., multiple holes 120) in the sample distribution ring member 127 can be positioned against the filter component 105. In some embodiments, the multiple holes 120 can help evenly distribute the sample to the filter component 105 after the buffer solution 103 from the capsule component 102 is released into the filter component 105.
[0173]
[0210] In some embodiments, the buffer solution 103 containing pathogen particles from the aerosol can be extracted from the exemplary aerosol collection device 100. For example, after a sample is collected (e.g., after a user blows into the sample transfer adapter 115), the sample transfer adapter 115 can be detached from the device body 126. For example, the sample transfer adapter 115 can be unscrewed from the upper plunger component 107 and / or the device body 126. In some embodiments, after the sample transfer adapter 115 is unscrewed from the upper plunger component 107, a rotational force can be exerted on the upper plunger component 640, causing it to rotate.
[0174]
[0211] In some embodiments, movement of the upper plunger component 107 may be controlled by engagement of the leg portion 109 with a set of ridge members 110A, 110B, 110C, and 110D disposed on and protruding from an inner lateral surface of the container component 106 of the exemplary aerosol collection device 100, as shown in FIG. 1C. For example, the upper plunger component 640 may be rotated past one or more vertical locking ridge members 110C (in some embodiments, each of the one or more vertical locking ridge members 110C has a triangular prism shape) and stopped by one or more vertical stop ridge members 110D (in some embodiments, each of the one or more vertical stop ridge members 110D has a rectangular base prism shape). These two sets of ridge members 110C and 110D can lock the upper plunger component 107 in a horizontally fixed position, where the leg portion 109 of the upper plunger component 107 is engaged with the lower plunger component 116, and the lower plunger component 116 is engaged with the filter component 105. In some embodiments, a vertical force is applied onto the upper plunger component 107 (e.g., the upper plunger component 107 is pressed down). After the upper plunger component 107 is pressed down, the leg portion 109 of the upper plunger component 107 engages with the lower plunger component 116, squeezing the sample liquid from the filter component 105 onto the bottom surface of the exemplary aerosol collection device 100.
[0175]
[0212] In some embodiments, the exemplary aerosol collection device 100 can include a touchless-based mechanism to extract sample liquid from the filter component 105. For example, the exemplary aerosol collection device 100 can include a groove component 122 disposed on a bottom surface of the device body of the exemplary aerosol collection device 100. The groove component 122 can be punctured to open an area for the sample to be extracted, as described in more detail herein.
[0176]
[0213] In some embodiments, aerosols from the sample may be trapped in the buffer solution 103 and / or the filter component 105, and air may be separated from the aerosols in the form of bubbles as the sample moves through the buffer solution 103 and / or the filter component 105.
[0177]
[0214] In some embodiments, the upper plunger component 107 can be depressed against the lower plunger component 116, which can push the sample liquid containing the aerosol out of the filter component 105, creating a pressure differential caused by a reduction in the volume inside the exemplary aerosol collection device 100. In some embodiments, the pressure differential can cause the sample liquid to be pushed out of the open groove component 122.
[0178]
[0215] In some embodiments, after the upper plunger component 107 is depressed, air can then enter a vent channel that includes the breath analyzer chamber 121. In the example shown in Figure 1B, a portion of the breath analyzer chamber 121 is positioned above the filter component 105, thus allowing air to escape from the filter component 105 after a vertical force is exerted on the filter component 105, details of which are described herein.
[0179]
[0216] In some embodiments, air can pass through a gap in the plunger body member 112 of the upper plunger component 107 and then exit the exemplary aerosol collection device 100 via a set of holes in the upper plunger component 107, as described in more detail herein. In some embodiments, the exemplary aerosol collection device 100 can contain a filter member 114 that prevents aerosols (e.g., disease-causing pathogens in a sample) from escaping the exemplary aerosol collection device 100. For example, a tube component 124 having a vent bluff ring member 123 that defines a portion of the central passage body can engage with the plunger body member 112 of the upper plunger component 107 such that air escaping through the vent channel must pass through the filter member 114 before exiting through the opening 113, as described in more detail herein.
[0180]
[0217] Thus, the exemplary aerosol collection device according to exemplary embodiments of the present disclosure can provide an effective means for sampling biological aerosol particles.
[0181]
[0218] According to various exemplary embodiments of the present disclosure, an exemplary device body of an aerosol collection device can include various components, including, but not limited to, a container component (examples of which are shown in FIGS. 2A-2D), a tube component (examples of which are shown in FIGS. 3A-3B), a lower plunger component (examples of which are shown in FIGS. 4A-5B), an upper plunger component (examples of which are shown in FIGS. 5A-5G), a cap component, a filter component, and / or a valve component. In the present disclosure, the term "component" refers to a physical portion or part of an aerosol collection device. In some embodiments, each component of an aerosol collection device may be replaceable. In some embodiments, each component can include one or more "members," and one or more "members" are part or portions of the component.

[0183]
[0220] In the examples shown in Figures 2A, 2B, 2C, and 2D, the container component 200 is shaped similar to a cylindrical shape. It is noted that while these figures provide examples of container components, the scope of the present disclosure is not limited to these figures. In some examples, the exemplary container component can be shaped similar to other shapes.

[0294] Referring now to FIG. 7A, an exemplary method for operating an exemplary aerosol collection device according to an example of the present disclosure includes removing a cap component of the device body portion 701 from an upper plunger component 703 of the device body portion 701, and connecting a sample transfer adapter 705 to a flow channel defined by at least the upper plunger component 703 and a tube component 707.
[0258]
[0295] As described above, the upper plunger component 703 includes a plunger head member defining a central bore having threads on an inner surface, and the sample transfer adapter 705 includes an extension portion having threads on an outer surface. The extension portion of the sample transfer adapter 705 can be fastened to the central bore of the plunger head member of the upper plunger component 703 via the threads.
[0259]
[0296] In some embodiments, the device body 701 includes at least one capsule component 709 that stores a buffer solution. In some embodiments, connecting the sample transfer adapter 705 to the upper plunger component 703 causes a vertical downward force to be exerted on the upper plunger component 703. In some embodiments, the upper plunger component 703 is positioned above an upper surface of the at least one capsule component 709, and the vertical downward force causes the release of buffer solution 716 from the at least one capsule component 709 into a filter component 713 within the device body 701, as described in more detail herein.
[0260]
[0297] In some embodiments, an exemplary method for assembling an exemplary aerosol collection device according to examples of the present disclosure includes inducing sample flow into the device body 701 through a flow channel. For example, when a user blows or coughs into the sample transfer adapter 705, the sample flows into the device body 701. In the example shown in FIG. 7A , the flow direction of the sample in the flow channel is indicated by dashed arrow 777. In some embodiments, the sample contacts the buffer solution 716 in the device body 701. For example, when a user blows or coughs into the sample transfer adapter 705, air can be blown into the buffer solution 716, forming one or more bubbles.
[0261]
[0298] Referring now to FIG. 7B, an exemplary method for operating an exemplary aerosol collection device according to an example of the present disclosure includes the steps of detaching the aerosol collection device from the upper plunger component 703 of the device body portion 701, and connecting / reconnecting the cap component 715 to the upper plunger component 703 of the device body portion 701 to seal the device body portion 701.
[0262]
[0299] As described above, the upper plunger component 703 includes a plunger head member defining a central bore having threads on an inner surface, and the cap component 715 includes an extension portion having threads on an outer surface. The extension portion of the cap component 715 can be fastened through the threads to the central bore of the plunger head member of the upper plunger component 703. In some embodiments, the cap component 715 is configured to seal the flow channel.
[0263]
[0300] Referring now to FIG. 7C, an exemplary method for operating an exemplary aerosol collection device according to an example of the present disclosure includes connecting an extraction cartridge 717 to the device body 701.
[0264]
[0301] In some embodiments, the device body 701 includes a locking component 719 that seals the bottom opening of the device body 701. In some embodiments, the locking component 719 prevents contamination. In some embodiments, connecting the extraction cartridge 717 includes disconnecting the locking component 719, shown in FIG. 7B , from the bottom of the container component 730 and connecting the extraction cartridge 717 to an opening on the bottom of the container component 730 (after the locking component 719 is removed), as described in detail herein. In some embodiments, the opening on the bottom of the container component 730 (after the locking component 719 is removed) can be connected to an inlet (e.g., an inlet of a waveguide cartridge) for further diagnostics.
[0265]
[0302] 7D , an exemplary method for operating an exemplary aerosol collection device according to examples of the present disclosure further includes exerting a rotational force on the upper plunger component 703, causing the upper plunger component 703 to translate from a first configuration to a second configuration. In the first configuration, a bottom surface of the upper plunger component 703 contacts a top surface of the at least one capsule component 709. In the second configuration, a bottom surface of the upper plunger component 703 contacts a top surface of the lower plunger component 733.
[0266]
[0303] In some embodiments, an exemplary method for operating an exemplary aerosol collection device according to examples of the present disclosure further includes exerting a vertical downward force on an upper surface of the upper plunger component 703, which causes the lower plunger component 733 to press against the filter component 713, thereby squeezing the sample liquid from the filter component 713.
[0267]
[0304] In some embodiments, an exemplary method for operating an exemplary aerosol collection device according to examples of the present disclosure includes extracting buffer solution 716 from device body 701 to extraction cartridge 717, details of which are described herein.
[0268]
[0305] 7E , an exemplary method for operating an exemplary aerosol collection device according to examples of the present disclosure includes detaching an extraction cartridge 717 from the device body 701. In some embodiments, the extraction cartridge 717 stores a buffer solution 716 containing aerosols extracted from the device body 701. In some embodiments, the buffer solution 716 containing the aerosols captured from the sample can be provided to downstream diagnostics to detect pathogens in the sample. For example, the buffer solution 716 containing the aerosols captured from the sample can be provided to a waveguide (such as, but not limited to, a waveguide cartridge) for further analysis and downstream diagnostics.
[0269]
[0306] As such, according to various examples of the present disclosure, exemplary aerosol collection devices and exemplary methods associated with the aerosol collection devices are provided. In some embodiments, the aerosol collection device can function as an aerosol collector utilizing a wet filter-based capture system. In some embodiments, the buffer is contained in a capsule component that is pierced before the sample is collected. In some embodiments, the aerosol collection device is self-contained and disposable. In some embodiments, the intended use of the aerosol collection device is designed into the aerosol collection device to reduce user error when using the aerosol collection device.
[0270]
[0307] In some embodiments, prior to using the aerosol collection device, the aerosol collection device is sealed with the cap component secured in place. In some embodiments, the cap component is removed and a sample transfer adapter (such as, but not limited to, a mask, straw, or hood connector) is screwed into the aerosol collection device. In some embodiments, the aerosol collection device is depressed, which forces the capsule component down onto the capsule extraction body member and releases the buffer onto the filter component. In some embodiments, a sample is collected through the sample transfer adapter and passes through the wetted filter. Once this is completed, in some embodiments, the sample transfer adapter is removed and the cap component is reattached to the aerosol collection device, which seals the aerosol collection device. The sample is then extracted from the aerosol collection device.
[0271]
[0308] 8 through 14B, an exemplary aerosol collection device 800 is illustrated in accordance with an exemplary embodiment of the present disclosure.
[0272]
[0309] 8, an exemplary diagram of an exemplary aerosol collection device 800 is shown. In the example shown in FIG. 8, the exemplary aerosol collection device 800 can include a sample transfer adapter and a device body. As shown, the sample transfer adapter can include a mask component 810, which is configured to attach to a device body 820.
[0273]
[0310] In various embodiments, the mask component 810 can include a facial interface member, an outer shell, an interior cavity, and a sampling channel. As shown in FIG. 8 , the mask component 810 includes a facial interface member 811, a mask outer shell 812, a mask interior cavity 813, and a sampling channel 814. In various embodiments, the mask component 810 can include a mask outer shell 812 and a facial interface member 811, where the mask outer shell 812 defines at least a portion of the structural exterior of the mask component 810, and the facial interface member 811 includes one or more contoured surfaces disposed around a portion of the mask outer shell 812 and defining an opening therein. For example, the one or more contoured surfaces of the facial interface member 811 can be configured to engage a portion of a user's face. In particular, one or more contoured surfaces of the facial interface member 811 may be configured to press against a portion of a user's face surrounding the user's mouth and / or nose, such that an opening defined by the facial interface member 811 may be configured to receive the user's mouth and / or nose. In such an exemplary situation, the user's mouth and / or nose are positioned within the opening defined by the facial interface member 811, and the one or more contoured surfaces of the facial interface member 811 may be configured such that at least a substantially airtight seal can exist along the one or more contoured surfaces that press against the user's face. As such, the mask component 810 may be configured such that a user's face engaged with the facial interface member 811 (e.g., such that the user's mouth and / or nose are positioned within the opening defined by the facial interface member 811) can allow the user's mouth and / or nose to be in fluid communication with the mask interior cavity 813.For example, an air sample provided by a user (e.g., exhaled or coughed by the user) may be administered into the mask interior cavity 813 of the exemplary mask component 810 via the facial interface member 811. As described in more detail herein, in some embodiments, the sample may include air and aerosols (which may contain pathogen particles).
[0274]
[0311] In various embodiments, the mask outer shell 812 can include a substantially hollow outer housing that at least partially defines the mask interior cavity 813 of the mask component 810. For example, the mask interior cavity 813 can include an interior volume within the mask outer shell 812, as defined by the hollow configuration of the mask outer shell 812. In various embodiments, the mask interior cavity 813 can be configured to receive an air sample through an opening defined by the facial interface member 811. For example, in the exemplary situation where the facial interface member 811 is engaged with the user's face, the mask interior cavity 813 can be configured to receive a sample (e.g., exhaled breath) from the user's mouth and / or nose through the opening defined by the facial interface member 811. In various embodiments, the mask interior cavity 813 may be fluidly connected to a sampling channel 814 of the mask component 810 such that an air sample within the mask interior cavity 813 (e.g., exhaled breath provided by a user) can further flow into the sampling channel 814 for delivery from the mask component 810 to the device body portion 820, as described in further detail herein.
[0275]
[0312] In various embodiments, the sampling channel 814 of the exemplary mask component 810 can include a conduit member configured to facilitate delivery of an air sample provided to the mask component 810 to downstream components of the exemplary aerosol collection device 800. For example, in various embodiments described herein, the sampling channel 814 can be configured to facilitate delivery of an air sample present in the mask interior cavity 813 to the device body portion 820 (e.g., into a flow channel described herein).
[0276]
[0313] 9 and 10 , the sampling channel 814 can include a tubular structure having a hollow central portion extending along its length, allowing air to pass therethrough. In various embodiments, the sampling channel 814 can include a first end disposed adjacent to and / or within the mask interior cavity 813 such that the sampling channel 814 is in fluid communication with the mask interior cavity 813 and configured to receive an air sample therefrom. Additionally, the sampling channel 814 can include a second end at an opposite, distal end of the tubular structure. In various embodiments, at least a distal portion of the sampling channel (e.g., the second end of the sampling channel 814) can protrude outward from the mask outer shell 812 and extend away from the surface of the mask outer shell 812. In various embodiments, the sampling channel 814 can further include a sample outlet portion 818 through which a sample traveling along the hollow interior of the sampling channel 814 can be dispensed. For example, the sample outlet portion 818 can be defined by an orifice positioned at a second end of the tubular structure of the sampling channel 814. As described herein, in various embodiments, the sample outlet portion 818 of the sampling channel 814 can embody the sample outlet portion of the mask component 810. In such an exemplary situation, a sample of air received by the mask component 810 can be dispensed from the mask component 810 to a fluidically downstream component of the aerosol collection device 800 (e.g., a flow channel of the device body portion 820) via the sample outlet portion 818.
[0277]
[0314] In various embodiments, the sampling channel 814 can be attached to at least a portion of the device body 820 to secure the mask component 810 relative to the device body 820. For example, in some embodiments, the sampling channel 814 can be attached to the flow channel (e.g., defined by at least the upper plunger component of the device body 820) via various means, including, but not limited to, mechanical means (e.g., the sampling channel 814 can be threaded into the device body 820 via threads provided about the exterior surface of the distal portion of the sampling channel 814). In various embodiments, the sampling channel 814 can be attached to the device body 820 such that the air flow path extending from the sample outlet portion 818 of the sampling channel 814 to the central bore of the device body 820 can remain at least substantially unobstructed, as described herein.
[0278]
[0315] While the above description provides examples of sampling channel 814, it is noted that the scope of the present disclosure is not limited to the above description. In some examples, sampling channel 814 may be embodied as, for example, but not limited to, an orifice extending through mask outer shell 812 configured to fluidly connect mask interior cavity 813 to downstream components of aerosol collection device 800 (e.g., device body portion 820), such that a sample present in mask interior cavity 813 can flow directly through the orifice in mask outer shell 812 to the downstream components of aerosol collection device 800. Furthermore, in various embodiments, one or more components of exemplary mask component 810 (e.g., sampling conduit 816, etc.) may be selectively removable from mask outer shell 812 of mask component 810.
[0279]
[0316] In various embodiments, the exemplary mask component 810 can include one or more adapter ventilation members configured to allow a predetermined volume of air dispensed from an exhaust outlet of a device body portion 820 coupled to the mask component 810 (e.g., from an opening / vent port in a plunger head member of an upper plunger component described herein) to flow into the surrounding environment. For example, the mask outer shell 812 of the exemplary mask component 810 can be defined in part by a mask ventilation surface 815. In various embodiments, in an exemplary situation where the sampling channel 814 of the mask component 810 is attached to the device body portion 820 (e.g., in an upper plunger component of the device body portion 820), the mask ventilation surface 815 may be positioned a predetermined distance away from the device body portion 820 and configured to provide an opening (e.g., an adapter ventilation opening) between the mask component 810 and the device body portion 820, such that at least a portion of the aerosol-depleted sample dispensed from the exhaust outlet portion of the device body portion 820 (e.g., from an opening / vent port in the plunger head member of the upper plunger component described herein) can be discharged through that opening into the surrounding environment. As further illustrated in Figures 12A and 12B, the exemplary mask component 810 may be configured such that the mask discharge surface 1215 of the mask component 810 is positioned a predetermined vertical distance away from the exterior surface 1226 of the device body 820 (e.g., the exterior surface of the aerosol collection device 800 (through which the air sample is dispensed through the exhaust outlet)) and provides a ventilation opening 1230, through which at least a portion of the aerosol-removed sample dispensed from the exterior surface 1226 can be discharged into the surrounding environment.As described herein, the sample can travel along the vent channel and through a filter member in the upper plunger component before being dispensed from the aerosol collection device 800. As such, aerosol can be removed from the sample by the filter member before being released into the surrounding environment.
[0280]
[0317] While the above description provides examples of ventilation openings 1230 defined (at least in part) by mask exhaust surface 1215, it is noted that the scope of the present disclosure is not limited to the above description. In some examples, ventilation openings 1230 may be embodied as an adapter ventilation member of exemplary mask component 810, the adapter ventilation member including one or more tubular channels configured to at least in part define an air flow path extending between the exhaust outlet of aerosol collection device 800 and the ambient environment, facilitating delivery of an air sample exhausted from aerosol collection device 800 through the adapter ventilation channels to the ambient environment.
[0281]
[0318] While the above description provides an example of a sample transfer adapter as an exemplary mask component 810, it is noted that the scope of the present disclosure is not limited to the above description. In some examples, the sample transfer adapter may be embodied as, for example, but not limited to, a sampling tunnel, a sampling hood, and / or other devices. In some embodiments, the sample transfer adapter may be in the form of a nasal swab capable of providing a biological sample.
[0282]
[0319] For example, as illustrated in FIGS. 13A and 13B , an exemplary aerosol collection device 1300 can include a sample transfer adapter embodied as a sampling tunnel 1310. In various embodiments, the sampling tunnel 1310 can be in the form of a tubular structure having, for example, a sample inlet portion 1311 configured to accept a sample from a user and a sampling tunnel body portion 1312 configured to deliver the sample accepted from the sample inlet portion 1311 to a device body portion 1320 (to which the sampling tunnel 1310 can be attached). For example, the sampling tunnel body portion 1312 can be tubular-shaped and / or can include a hollow portion in the center that allows air to pass through. In some embodiments, the sampling tunnel 1310 can be embodied as a breathing straw. As such, a sample (e.g., exhaled breath from a user) can be administered into the exemplary device body portion 1320 via the sampling tunnel 1310.
[0283]
[0320] In various embodiments, the sampling tunnel 1310 can be configured to attach to the exemplary device body 1320 via means at least substantially similar to those of the exemplary mask component 810 described above. Further, in various embodiments, the exemplary sampling tunnel 1310 can include one or more adapter ventilation members configured to allow a predetermined volume of air dispensed from an exhaust outlet of the device body 1320 coupled to the sampling tunnel 1310 (e.g., from an opening / vent port in a plunger head member of an upper plunger component described herein) to flow into the surrounding environment. For example, the sampling tunnel 1310 can include a sampling tunnel ventilation surface 1315. In various embodiments, in an exemplary situation where the sampling tunnel 1310 is attached to the device body 1320, as described herein, the sampling tunnel ventilation surface 1315 may be positioned a predetermined distance from the device body 1320 and configured to provide an opening (e.g., an adapter ventilation opening) between the sampling tunnel 1310 and the device body 1320, through which at least a portion of the aerosol-depleted sample dispensed from the exhaust outlet of the device body 1320 (e.g., from an opening / vent port in a plunger head member of an upper plunger component described herein) may be discharged into the surrounding environment.As shown in Figures 13A and 13B, the sampling tunnel ventilation surface 1315 is positioned a predetermined vertical distance from the exterior surface 1326 of the device body 1320 (e.g., the exterior surface of the device body 1320 through which the air sample is dispensed through the exhaust outlet) and is configured to provide an adapter ventilation opening 1330, such that at least a portion of the aerosol-depleted sample dispensed from the exterior surface 1326 can be discharged into the surrounding environment through the adapter ventilation opening 1330.
[0284]
[0321] 14A and 14B illustrate an exemplary aerosol collection device 1400 including a sample transfer adapter embodied as a sampling hood 1410. In various embodiments, the sampling hood 1410 can define a sampling channel 1414 having a sample inlet portion 1411 configured to accept a sample from a user, for example. The sampling channel 1414 can be embodied as a tubular structure configured to deliver the accepted sample from the sample inlet portion 1411 to a device body portion 1420 (to which the sampling channel 1414 can be attached). For example, the sampling channel 1414 can be a tubular structure and / or can include a hollow portion in the center that allows air to pass through. In various embodiments, the sampling channel 1414 can further include a sampling channel outlet portion 1416 through which a sample traveling along the hollow interior of the sampling channel 1414 can be dispensed. For example, the sampling hood outlet portion 1417 may be defined by an orifice positioned at the opposite end of the tubular structure of the sampling channel 1414 relative to the sample inlet portion 1411. In various embodiments, a sample of air received by the sampling hood 1410 may be dispensed from the sampling hood 1410 via the sampling channel outlet portion 1416 to a fluidically downstream component of the aerosol collection device 1400 (e.g., a flow channel in the device body portion 1420).
[0285]
[0322] In various embodiments, the sampling hood 1410 can be configured to attach to the exemplary device body 1420 via means at least substantially similar to those of the exemplary mask component 810 and / or sampling tunnel 1310 described above. Further, in various embodiments, the exemplary sampling hood 1410 can include one or more adapter ventilation members configured to allow a predetermined volume of air dispensed from an exhaust outlet of the device body 1420 coupled to the sampling hood 1410 to flow into a downstream environment fluidly connected thereto. For example, the sampling hood 1410 can include a hood cover 1412, which is embodied as a substantially hollow shell housing that at least partially defines a hood interior cavity 1413 of the sampling hood 1410. For example, the hood interior cavity 1413 of the sampling hood 1410 can include at least a portion of an interior volume within the hood cover 1412, as defined by the hollow configuration of the hood cover 1412. In various embodiments, the sampling hood 1410 can include a sampling hood outlet portion 1417 through which sample received in the hood interior cavity 1413 can flow and be dispensed from the sampling hood 1410. For example, the sampling hood outlet portion 1417 can be an orifice extending through the hood cover 1412, which is configured to fluidly connect the hood interior cavity 1413 to a downstream environment connected to the sampling hood outlet portion 1417, such that the air sample in the hood interior cavity 1413 (e.g., sample dispensed from the device body portion 1420) can flow through the sampling hood outlet portion 1417 to the downstream environment (e.g., a flow channel).
[0286]
[0323] In various embodiments, the hood interior cavity 1413 can be configured to receive a predetermined volume of air dispensed from the exhaust outlet of the device body 1420. For example, in the exemplary situation where the sampling hood 1410 is attached to the device body 1420 (e.g., via an attachment means at the distal end of the sampling channel 1414), the hood interior cavity 1413 can be configured to receive a sample dispensed from the exhaust outlet of the device body 1420. As shown in FIGS. 14A and 14B , the hood cover 1412 can include a hood cover sealing surface 1415 configured to engage a surface of the device body 1420 to create at least a substantially airtight seal between the sampling hood 1410 and the device body 1420 along the hood cover sealing surface 1415. For example, in the exemplary situation where the sampling channel 1414 of the sampling hood 1410 is attached to the device body 1420 (e.g., at an upper plunger component of the device body 1420), the sampling hood 1410 may be configured such that the hood cover sealing surface 1415 physically engages one or more exterior surfaces 1426 of the device body 1420 (e.g., the exterior surfaces of the device body 1420 through which the air sample is dispensed through the vent channels) to provide a sealed perimeter around the one or more exterior surfaces 1426 of the device body 1420. The hood cover sealing surface 1415 may be configured to prevent sample dispensed from the device body 1420 (e.g., via one or more vent channels disposed around the exterior surfaces 1426) from flowing directly into the surrounding environment without passing through at least a portion of the sampling hood 1410 (e.g., the sampling hood outlet portion 1417).14B, the sampling hood 1410 may be attached to the device body 1420 such that the sealed perimeter provided by the hood cover sealing surface 1415 extends along the exterior surface 1426 and surrounds each of one or more outlets of one or more vent channels of the device body 1420 (e.g., surrounding one or more openings / vent ports in a plunger head member of an upper plunger component described herein). In such an exemplary configuration, the sampling hood 1410 may be configured such that the entire sample dispensed from the device body 1420 (e.g., via one or more vent channels) is received by the hood interior cavity 1413 and directed toward the sampling hood outlet 1417.
[0287]
[0324] In various embodiments, a portion of the hood cover 1412 at least substantially adjacent the sampling hood outlet portion 1417 can be configured to mechanically attach to one or more external components defining one or more downstream environments. For example, the hood cover 1412 can be configured to mechanically attach to an external component defining the controlled downstream environment to fluidly connect the sampling hood outlet portion 1417 to the controlled downstream environment. In such an exemplary situation, the sampling hood outlet portion 1417 can be configured to fluidly connect the hood interior cavity 1413 to the controlled downstream environment such that sample dispensed from the device body portion 1420 into the hood interior cavity 1413 can further flow through the sampling hood outlet portion 1417 to the controlled downstream environment. In various embodiments, the controlled environment can exhibit one or more predefined environmental conditions, such as, for example, a known pressure, temperature, volume, and / or aerosol composition. For example, a controlled environment disposed downstream from the sampling hood outlet portion 1417 may be utilized to enable experimentation, observation, and / or analysis of air samples dispensed into the controlled environment from the device body portion 1420.
[0288]
[0325] Various embodiments of the present disclosure can provide technical advantages and benefits in sample collection, such as, but not limited to, breath aerosol collection. As explained above, exemplary aerosol collection devices according to examples of the present disclosure can include a buffer. In some embodiments, the buffer can be tailored to a particular subsequent pathogen detection technique.
[0289]
[0326] When samples are collected by nasal swab, an intermediate step is required to extract the pathogen from the swab into a liquid medium. The liquid medium can be a buffer, but the exact composition of the medium will vary depending on the immediate plans for the sample. For example, if the sample will be transported via mail or stored prior to analysis, a stabilizing medium may be used. If the sample will be analyzed immediately (e.g., within 2-3 hours), the medium may contain chemicals intended to extract and preserve the RNA / DNA context for a PCR-type assay.
[0290]
[0327] According to examples of the present disclosure, implementing an aerosol collection device can eliminate the need for a nasal swab, and the physics of the aerosol collection device are not affected by the additional chemical components of the liquid medium. For example, a specific liquid medium for a specific downstream analysis can be used as a buffer. Various embodiments of the present disclosure can combine the sample collection step with the pathogen extraction step, which can save additional labor and reduce the risk of sample contamination. In some embodiments, different liquids can be stored in a set of capsule components within a single aerosol collection device, allowing the liquids to be combined and reacted at the moment of use.
[0291]
[0328] 15A, 15B, 15C, and 15D illustrate exemplary views of an exemplary capsule component 1500 according to various examples of the present disclosure. In particular, FIG. 15A illustrates an exemplary top view of the exemplary capsule component 1500. FIG. 15B illustrates an exemplary bottom view of the exemplary capsule component 1500. FIG. 15C illustrates an exemplary perspective view of the exemplary capsule component 1500. FIG. 15D illustrates another exemplary perspective view of the exemplary capsule component 1500.
[0292]
[0329] As shown in the exemplary capsule component 1500 illustrated in FIGS. 15A, 15B, 15C, and 15D, the exemplary capsule component 1500 includes a holder member 1501 and a cap member 1503.
[0293]
[0330] In some embodiments, the buffer solution is sealed within the holder member 1501 by a cap member 1503. For example, the holder member 1501 defines a cavity having an opening on a bottom surface 1505 of the holder member 1501. In some embodiments, the buffer solution is disposed within the cavity defined by the holder member 1501. In some embodiments, the cap member 1503 seals the opening on the bottom surface 1505 of the holder member 1501.
[0294]
[0331] In some embodiments, the cap member 1503 is attached to the holder member 1501 through a chemical adhesive, such as, but not limited to, a chemical glue. In some embodiments, the cap member 1503 is attached to the holder member 1501 through other means.
[0295]
[0332] 15C and 15D, the holder member 1501 can include a handle portion 1507 and a body portion 1509. In the example shown in Figures 15C and 15D, the body portion 1509 stores a buffer solution. In some embodiments, the handle portion 1507 extends from a top surface of the body portion 1509.
[0296]
[0333] In some embodiments, the handle portion 1507 can define an opening 1511. In some embodiments, after the aerosol collection device has been used, a hook (e.g., an Allen wrench, etc.) can be used to engage the opening 1511 to pull the capsule component 1500 out of the aerosol collection device.
[0297]
[0334] In some embodiments, an exemplary aerosol collection device can include one or more capsule components. For example, an exemplary aerosol collection device can include a first capsule component that stores a first buffer solution and a second capsule component that stores a second buffer solution. In some embodiments, the first buffer solution is the same as the second buffer solution. In some embodiments, the first buffer solution is different from the second buffer solution.
[0298]
[0335] For example, the first buffer and / or the second buffer can contain chemicals that extract and / or preserve genetic proteins collected from the sample. In some embodiments, the first buffer and / or the second buffer can contain chemicals that can assist in downstream analysis of the collected sample. In some embodiments, the first buffer and the second buffer can combine and react when they are released. In some embodiments, the buffer can have a pH level and ion concentration level similar to that of human cells. In such embodiments, the buffer is a fluid that preserves the biological sample.
[0299]
[0336] In some embodiments, an exemplary buffer solution can include two reagents that interact with biological cells or proteins to produce either a color change or other property change, indicating the presence of the target cells or proteins. Additionally or alternatively, the capsule components can contain buffer solutions for positive and negative controls targeted to biological entities for downstream analysis. For example, some buffer solutions can assist in identifying and / or detecting biological entities when the target virus is present in the sample. Additionally or alternatively, some buffer solutions can assist in identifying and / or detecting biological entities when the target virus is not present in the sample. In some embodiments, some components can contain the same positive and / or negative controls, and as such, the capsule components can contain different solutions. In some embodiments, the capsule components can store 0.7 milliliters of buffer solution. In some embodiments, the capsule components can store less than 0.7 milliliters or more than 0.7 milliliters of buffer solution (e.g., approximately 0.1 milliliters).
[0300]
[0337] In some embodiments, the exemplary aerosol collection device may include three capsule components, i.e., a first capsule component, a second capsule component, and a third capsule component. In some embodiments, the buffers stored in each of the first capsule component, the second capsule component, and the third capsule component are the same. In some embodiments, two of the buffers stored in each of the first capsule component, the second capsule component, and the third capsule component are the same. In some embodiments, the buffers stored in each of the first capsule component, the second capsule component, and the third capsule component are different. In some embodiments, the exemplary aerosol collection device may include less than three or more than three capsule components.
[0301]
[0338] 16 illustrates an exemplary view of at least a portion of an exemplary capsule extraction body member 1602, according to an exemplary embodiment of the present disclosure. In the example shown in FIG. 16, the capsule extraction body member 1602 includes a protrusion 1606 positioned on an upper surface 1604 of the capsule extraction body member 1602.
[0302]
[0339] 17A and 17B illustrate exemplary views of at least a portion of an exemplary capsule component 1701 and an exemplary capsule extraction body member 1703 according to an exemplary embodiment of the present disclosure.
[0303]
[0340] As described above, an exemplary aerosol collection device according to examples of the present disclosure can include a capsule extraction body member 1703 and at least one capsule component (e.g., capsule component 1701). In some embodiments, capsule component 1701 stores a buffer solution, as described above. In some embodiments, capsule component 1701 is positioned on capsule extraction body member 1703.
[0304]
[0341] In some embodiments, the aerosol collection device includes a container component 1711 having an inner lateral surface 1713. In some embodiments, the container component 1711 includes at least two vertical ridge members disposed on the inner lateral surface 1713 of the container component 1711. In the example shown in FIG. 17A , the exemplary container component 1711 includes a first vertical ridge member 1715 and a second vertical ridge member 1717.
[0305]
[0342] In some embodiments, at least a portion of each of the at least one capsule component is positioned between at least two vertical ridge members. In the example shown in FIG. 17A , the handle portion 1719 of the capsule component 1701 is positioned between the first vertical ridge member 1715 and the second vertical ridge member 1717. As such, in some embodiments, the first vertical ridge member 1715 and the second vertical ridge member 1717 secure the position of the capsule component 1701 and prevent the capsule component 1701 from sliding along the inner lateral surface 1713 of the container component 1711.
[0306]
[0343] In some embodiments, the container component 1711 includes at least one horizontal ridge member (e.g., horizontal ridge member 1721) disposed on the inner lateral surface 1713 of the container component 1711. In some embodiments, at least the top surface of each of the at least one capsule component is coplanar with the top surface of the at least one horizontal ridge. In the example shown in FIG. 17A , the top surface of the capsule component 1701 (e.g., the top surface of the handle portion 1719 of the capsule component 1701) is coplanar with the top surface of the horizontal ridge member 1721.
[0307]
[0344] 17B, the capsule extraction body member 1703 includes a protrusion 1705 extending from the top surface of the capsule extraction body member 1703. In some embodiments, the cap member 1707 of the capsule component 1701 is positioned over the protrusion 1705. Because the protrusion 1705 extends from the top surface of the capsule extraction body member 1703, only a portion of the cap member 1707 contacts the protrusion 1705 of the capsule extraction body member 1703, and an air gap 1709 is formed between the top surface of the capsule extraction body member 1703 (other than the protrusion 1705) and the cap member 1707 of the capsule component 1701.
[0308]
[0345] Various embodiments of the present disclosure can provide various technical advantages and benefits. For example, an exemplary aerosol collection device according to examples of the present disclosure can include at least one capsule component. In some embodiments, the at least one capsule component is engaged and punctured during operation of the aerosol collection device to provide liquid insertion into the filter component at the moment of use, which can prevent premature liquid insertion and can extend the shelf life of the aerosol collection device.
[0309]
[0346] 18A and 18B illustrate at least a portion of an exemplary capsule component and / or a portion of an exemplary upper plunger component, respectively, according to exemplary embodiments of the present disclosure. In particular, FIG. 18A illustrates a bottom portion of an exemplary upper plunger component 1803 and an upper portion of a capsule component 1801. FIG. 18B illustrates a bottom portion of a capsule component 1801 and an upper portion of a capsule extraction body member 1805.
[0310]
[0347] As described above, an exemplary aerosol collection device according to examples of the present disclosure can include at least one capsule component and an upper plunger component. In the example shown in Figures 18A and 18B, the exemplary aerosol collection device can include at least capsule component 1801 and upper plunger component 1803.
[0311]
[0348] In some embodiments, capsule component 1801 stores a buffer solution. In some embodiments, the top surface of capsule component 1801 contacts the bottom surface of upper plunger component 1803 (e.g., the bottom surface of at least one leg portion), as shown in FIG.
[0312]
[0349] As described above, capsule component 1801 can include a holder member 1807 and a cap member 1809. In some embodiments, holder member 1807 of capsule component 1801 defines a cavity having an opening on a bottom surface of capsule component 1801 for storing a buffer solution. In some embodiments, cap member 1809 seals the opening of holder member 1807.
[0313]
[0350] In some embodiments, at least a portion of the cap member 1809 contacts the capsule extraction body member 1805. For example, a portion of the cap member 1809 contacts a protrusion 1813 of the capsule extraction body member 1805, and an air gap 1811 is formed between the cap member 1809 and the top surface of the capsule extraction body member 1805, similar to that described above.
[0314]
[0351] In some embodiments, the upper plunger component 1803 contacts the top surface of the holder member of the capsule component 1801 (eg, the top surface of the handle portion of the holder member).
[0315]
[0352] In some embodiments, a vertical downward force can be exerted on the top surface of the upper plunger component 1803. The vertical force can be triggered, for example, but not limited to, by connecting an aerosol collection device to the upper plunger component 1803, as described above.
[0316]
[0353] In some embodiments, in response to receiving a vertically downward force applied to an upper surface of the upper plunger component 1803, the upper plunger component 1803 is configured to transmit the vertically downward force to the capsule component 1801, causing vertical movement of the capsule component 1801. In some embodiments, the vertical movement of the capsule component 1801 causes the capsule extraction body member 1805 (e.g., the protrusion 1813) to break the cap member 1809 of the capsule component 1801. After the cap member 1809 is broken, the buffer solution stored in the holder member 1807 of the capsule component 1801 flows onto the capsule extraction body member 1805. In some embodiments, the cap member 1809 can include a material such as, but not limited to, polypropylene (e.g., the cap member 1809 can be in the form of a polypropylene film). Additionally or alternatively, the cap member 1809 can include other materials.
[0317]
[0354] 19 and 20 each illustrate an exemplary view of at least a portion of an exemplary aerosol collection device after the buffer solution has been released, according to an example of the present disclosure.
[0318]
[0355] Referring now to FIG. 19, an exemplary cross-sectional view of an exemplary aerosol collection device 1900 is shown, according to an example of the present disclosure.
[0319]
[0356] 19 , the exemplary aerosol collection device 1900 includes a first vertical ridge member 1901 and a second vertical ridge member 1903 disposed on an inner lateral surface 1909 of the exemplary aerosol collection device 1900. As described above, the handle portion of the holder member of the capsule component 1902 can be positioned and secured between the first vertical ridge member 1901 and the second vertical ridge member 1903. In the example shown in FIG. 19 , when a vertical downward force is exerted on the top surface of the upper plunger component 1911, the leg portion 1907 of the upper plunger component 1911 moves downward between the first vertical ridge member 1901 and the second vertical ridge member 1903, pushing the handle portion of the holder member of the capsule component 1905, causing it to move downward.
[0320]
[0357] In some embodiments, after the cap member of the capsule component is broken by the capsule extraction body member (e.g., a protrusion on the upper surface of the capsule extraction body member), the capsule component moves downward until it is stopped by the capsule extraction body member. In the example shown in FIG. 19, the capsule component 1902 is at least partially stopped by the capsule extraction body member 1904. In this state, the capsule extraction body member 1904 is at least partially within the cavity of the capsule component 1902 (where the buffer solution was previously stored).
[0321]
[0358] As described above, according to examples of the present disclosure, a filter component is positioned adjacent to the capsule extraction body member of the container component of an exemplary aerosol collection device. Referring now to Figure 20, an exemplary cross-sectional view of at least a portion of an exemplary aerosol collection device 2000 is shown.
[0322]
[0359] 20 , the filter component 2002 is positioned adjacent to the capsule extraction body member 2004. After receiving a vertical downward force, the upper plunger component 2008 pushes the capsule component 2006 downward, causing the capsule extraction body member 2004 to break the seal component of the capsule component 2006 and release the buffer solution from the capsule component 2006. Because the filter component 2002 is positioned adjacent to the capsule extraction body member 2004, the buffer solution flows to the filter component 2002 and wets the filter component 2002.
[0323]
[0360] As such, according to examples of the present disclosure, an exemplary method for operating an aerosol collection device is provided. In some embodiments, the exemplary method includes exerting a vertically downward force on an upper surface of the upper plunger, causing the release of buffer solution from at least one capsule component onto the filter component. As described above, the exemplary method can further include providing a sample to the filter component (for example, but not limited to, a user coughing into the aerosol collection device through a sample transfer adapter described herein).
[0324]
[0361] As described above, exemplary embodiments of the present disclosure provide various technical advantages and benefits, for example, providing an aerosol collection device capable of defining a flow channel for collecting aerosol from a sample and / or a vent channel for expelling a sample from the aerosol collection device.
[0325]
[0362] FIG. 21 illustrates at least a portion of an exemplary upper plunger component 2101 and at least a portion of an exemplary capsule component 2103 according to an example of the present disclosure.
[0326]
[0363] 21 , the bottom surface of the upper plunger component 2101 contacts the top surface of the capsule component 2103. For example, the bottom surface of the leg portion 2111 of the upper plunger component 2101 contacts the top surface of the capsule component 2103. As described above, the example upper plunger component 2101 is capable of receiving a vertically downward force exerted on the top surface of the example upper plunger component 2101. The vertically downward force can cause the example upper plunger component 2101 to move downward between the first vertical ridge member 2105 and the second vertical ridge member 2107, which are disposed on the inner lateral surface 2109 of the container component. The vertical downward force may further cause the cap member of the capsule component 2103 to be broken and the buffer solution to be released from the capsule component 2103.
[0327]
[0364] As described above, the first vertical ridge member 2105 and the second vertical ridge member 2107 can include at least one vertical locking ridge member and at least one vertical stop ridge member. Referring now to Figure 22, an exemplary ridge member is illustrated positioned on an inner lateral surface 2208 of an exemplary container component according to an example of the present disclosure.
[0328]
[0365] In the example shown in Figure 22, vertical locking ridge 2202, vertical stop ridge 2204, and horizontal ridge 2206 are disposed on an inner side surface 2208 of the container component. In the example shown in Figure 22, vertical locking ridge 2202 is connected to horizontal ridge 2206 and is disposed orthogonal to horizontal ridge 2206. Additionally or alternatively, vertical stop ridge 2204 is connected to horizontal ridge 2206 and is disposed orthogonal to horizontal ridge 2206.
[0329]
[0366] In some embodiments, the vertical locking ridge 2202 can include a bevel that extends from the inner lateral surface 2208 at an angle less than 90 degrees. In some embodiments, the angle is 45 degrees. In some embodiments, the angle is 51 degrees. In some embodiments, the angle can be other values. The angle allows the vertical locking ridge 2202 to deflect inward instead of stopping the rotation of the legs of the upper plunger component. In other words, the bevel allows the legs of the upper plunger component to rotate and slide past the vertical locking ridge 2202, but prevents the legs of the upper plunger component from rotating back after they have rotated past the vertical locking ridge 2202. For example, before sliding past the vertical locking ridge 2202, the upper plunger component can be in a first configuration, in which the upper plunger component is in contact with the capsule component. After sliding over the vertical locking ridge member 2202, the upper plunger component can be in a second configuration in which the upper plunger component is in contact with the lower plunger component, details of the first and second configurations being described further herein.
[0330]
[0367] In some embodiments, the vertical stop ridge member 2204 can include two side surfaces, each having an orthogonal orientation with the inner lateral surface 2208. In some embodiments, the vertical stop ridge member 2204 includes a top surface, connected to the two side surfaces, having the same curvature as the inner lateral surface 2208. In some embodiments, the vertical stop ridge member 2204 does not include a slope that extends at an angle of less than 90 degrees from the inner lateral surface 2208. As such, the vertical stop ridge member 2204 prevents the leg portion of the upper plunger component from rotating and sliding past the vertical stop ridge member 2204.
[0331]
[0368] In some embodiments, the height of the vertical locking ridge member 2202 (e.g., the distance between the top point of the vertical locking ridge member 2202 and the point above the inner lateral surface 2208 from which the vertical locking ridge member 2202 protrudes) is less than (e.g., half the height of) the height of the vertical stop ridge member 2204 (e.g., the distance between the top surface of the vertical stop ridge member 2204 and the inner lateral surface 2208 from which the side surface of the vertical stop ridge member 2204 protrudes), such that the leg portion of the upper plunger component can slide over the vertical locking ridge member 2202 but cannot slide over the vertical stop ridge member 2204.
[0332]
[0369] Additionally or alternatively, the height of the vertical locking ridge member 2202 (e.g., the distance between the top point of the vertical locking ridge member 2202 and the point on the inner lateral surface 2208 from which the vertical locking ridge member 2202 projects) is less than (e.g., half the height of) the horizontal ridge member 2206 (e.g., the distance between the top point of the horizontal ridge member 2206 and the point on the inner lateral surface 2208 from which the horizontal ridge member 2206 projects).
[0333]
[0370] 23 and 24 illustrate exemplary views of at least a portion of an exemplary aerosol collection device after the upper plunger component has been rotated.
[0334]
[0371] In particular, Figure 23 illustrates an exemplary cross-sectional view of at least a portion of an exemplary upper plunger component 2303. In the example shown in Figure 23, the leg portion 2301 of the exemplary upper plunger component 2303 has been rotated and slid past a vertical locking ridge member 2305 and stopped at a vertical stop ridge member 2307. For example, a user can rotate the plunger head member of the upper plunger component, which causes the leg portion 2301 of the exemplary upper plunger component 2303 to rotate.
[0335]
[0372] In some embodiments, rotation and sliding of the leg portion 2301 of the upper plunger component 2303 is vertically restricted by a horizontal ridge member 2206. In some embodiments, the horizontal ridge member 2206 prevents the leg portion 2301 (and the upper plunger component 2303) from moving vertically upward.
[0336]
[0373] FIG. 24 illustrates an exemplary cross-sectional view of an exemplary aerosol collection device 2400 after the upper plunger component 2401 has been rotated.
[0337]
[0374] As explained above, the leg portions 2403 of the upper plunger component 2401 are stopped from further rotation by vertical stop ridge members 2405. In the configuration shown in FIG. 24 , the bottom surface of the upper plunger component 2401 (e.g., the bottom surface of the leg portions 2403) contacts the top surfaces of the plunger support wings 2407 of the lower plunger component 2409.
[0338]
[0375] As such, examples of the present disclosure can provide an exemplary aerosol collection device that includes a lower plunger component and an upper plunger component. Similar to that described above, the lower plunger component can include a plurality of plunger support wings, each of which is positioned between two of the plurality of capsule components.
[0339]
[0376] In some embodiments, the upper plunger component is configured to translate from a first configuration to a second configuration, the second configuration being triggered by a rotational force (e.g., a user rotating a plunger head member of the upper plunger component). In other words, the upper plunger component, which may start in the first configuration, may be rotated to arrive at the second configuration.
[0340]
[0377] In a first configuration (e.g., as shown in FIG. 21 ), the bottom surface of the upper plunger component contacts the top surface of each of the plurality of capsule components, e.g., the bottom surface of at least one leg portion contacts the top surface of each of the plurality of capsule components.
[0341]
[0378] As described above, in some embodiments, the lower plunger component and the upper plunger component are housed within a container component having at least one vertical locking ridge and at least one vertical stop ridge disposed on an inner lateral surface of the container component. In some embodiments, a rotational force on the upper plunger component causes at least a portion of the at least one leg portion to rotate (from a first configuration) past the at least one vertical locking ridge and stop at the at least one vertical stop ridge (and reach a second configuration).
[0342]
[0379] In a second configuration (e.g., as shown in FIG. 24), the bottom surface of the upper plunger component contacts the top surface of each of the plurality of plunger support wings of the lower plunger component, e.g., the bottom surface of at least one leg portion contacts the top surface of each of the plurality of plunger support wings.
[0343]
[0380] Thus, exemplary methods for operating an aerosol collection device are provided in accordance with examples of the present disclosure. The exemplary method can include exerting a rotational force on an upper plunger component, causing the upper plunger component to translate from a first configuration to a second configuration. In some embodiments, the exemplary method further includes exerting a normal force on an upper surface of the upper plunger after exerting the rotational force, details of which are described in connection with at least Figures 25 through 29B.
[0344]
[0381] 25 illustrates an example isolated view showing an example tube component 2503 and an example upper plunger component 2501 according to an example of the present disclosure. In particular, FIG. 25 illustrates an example structural relationship between the example tube component 2503 and the example upper plunger component 2501 according to an example of the present disclosure.
[0345]
[0382] In the example shown in FIG. 25, the upper portion of the pipe member 2505 of the tube component 2503 is positioned within the central collar portion 2507 of the upper plunger component 2501 .
[0346]
[0383] In the exemplary assembled aerosol collection device, when a vertical force is applied to the top surface of the upper plunger component 2501, at least a portion of the bent bluff ring member 2513 of the tube component 2503 enters into the gap 2511 between the central ring portion 2507 of the upper plunger component 2501 and the intermediate ring portion 2509 of the upper plunger component 2501. In the example shown in FIG.
[0347]
[0384] 26A, 26B, and 26C each illustrate at least a portion of an exemplary aerosol collection device 2600 according to an example of the present disclosure.
[0348]
[0385] 26A, an exemplary aerosol collection device 2600 includes an upper plunger component 2602 and a tube component 2604. Similar to that described above, the upper plunger component 2602 includes a central ring portion 2606 and an intermediate ring portion 2608. In the example shown in FIG. 26A, the central ring portion 2606 is disposed within the intermediate ring portion 2608, forming a gap between the central ring portion 2606 and the intermediate ring portion 2608.
[0349]
[0386] In some embodiments, the tube component 2604 includes a bent bluff ring member 2605. In some embodiments, at least a portion of the central ring portion 2606 of the upper plunger component 2602 is positioned within and in contact with the bent bluff ring member 2605 of the tube component 2604.
[0350]
[0387] In some embodiments, the upper plunger component 2602 includes a plunger head member 2610 that defines a central bore 2612. In some embodiments, the tube component 2604 includes a pipe member 2614 that is positioned at least partially within the central annular portion 2606 and is connected to the central bore 2612, forming a portion of a flow channel for receiving a sample within the aerosol collection device 2600.
[0351]
[0388] For example, a sample may enter aerosol collection device 2600 through central bore 2612 (from the sample transfer adapter), travel through pipe member 2614, travel downward past valve component 2616, and arrive into valve support ring member 2618. Dashed arrow 2620 in FIG. 26A indicates an exemplary flow direction of a sample in the flow channel. For example, the flow channel may include a portion defined by at least central bore 2612, pipe member 2614 (including the gap between valve component 2616 and the inner surface of pipe member 2614), and valve support ring member 2618. In such an example, the sample may travel through central bore 2612, through pipe member 2614 (including the gap between valve component 2616 and the inner surface of pipe member 2614), and arrive into valve support ring member 2618. In some embodiments, the sample may interact with a buffer solution in filter component 2622. For example, when a user blows air into the sample transfer adapter, the air travels through the flow channel and into the buffer solution, forming one or more bubbles.
[0352]
[0389] In some embodiments, a sample can be expelled from the aerosol collection device 2600 through a vent channel. The vent channel can include at least the space between the outer surface of the tube component 2604 and the lower plunger component 2630 and the gap between the central annular portion 2606 and the intermediate annular portion 2608. For example, the sample (e.g., air) can travel upward from the filter component 2622, along the gap between the outer surface of the tube component 2604 and the lower plunger component 2630, along the gap between the central annular portion 2606 and the intermediate annular portion 2608, and out of the aerosol collection device through one or more openings / ports on the plunger head member 2610. The dashed arrow 2624 in FIG. 26A indicates an exemplary vent direction for the sample in the vent channel.
[0353]
[0390] For example, when a user provides a sample to the aerosol collection device 2600 by coughing or blowing air into the aerosol collection device 2600 through a sample transfer adapter connected to the central bore 2612, the sample moves through the aerosol collection device 2600 by flowing through a flow channel that guides the air to the filter component 2622, and then is expelled from the aerosol collection device 2600 through a vent channel.
[0354]
[0391] 26B and 26C each illustrate an enlarged view of at least a portion of the aerosol collection device 2600. In the example shown in FIGS. 26B and 26C, a gap exists between the top surface of the vent bluff ring member 2605 and the bottom surface of the intermediate ring portion 2608, which is part of a vent channel that allows the sample to be expelled from the aerosol collection device 2600. Additionally, as shown in FIG. 26C, a sealing ridge 2631 may be disposed on the inner surface of the intermediate ring portion 2608. In some embodiments, the sealing ridge 2631 may be shaped similar to a ring. In some embodiments, the sealing ridge 2631 may be shaped differently. The sealing ridge 2631 is configured to seal the vent channel when a vertical downward force is applied to the upper plunger component, as described in more detail herein.
[0355]
[0392] 27A and 27B illustrate an exemplary view of an exemplary upper plunger component 2700 in relation to the flow and vent channels.
[0356]
[0393] As explained above, the sample can enter the aerosol collection device through opening 2701 in central bore 2703 of plunger head member 2705. The sample passes through tubing member 2709, which forms part of a flow channel, the flow direction of which is indicated by dashed arrow 2711 in FIG. 27B.
[0357]
[0394] As described above, the central ring portion 2715 and the intermediate ring portion 2713 define a portion of a vent channel for expelling the sample. For example, at least a portion of the gap between the central ring portion 2715 and the intermediate ring portion 2713 of the plunger body member 2707 defines at least a portion of the vent channel. The sample then travels through the aperture 2717 in the plunger head member 2705 and exits the aerosol collection device through the opening 2719. As described above, in some embodiments, a filter 2721 can be disposed between the plunger head member 2705 and the plunger body member 2707. In FIG. 27B , the dashed arrow 2723 illustrates the vent direction of the sample in the vent channel.
[0358]
[0395] 28 illustrates an exemplary view of at least a portion of an exemplary tube component and a portion of an exemplary upper plunger component according to an example of the present disclosure. In particular, FIG. 28 illustrates the structural relationship between the exemplary tube component and the exemplary upper plunger component when a vertically downward force is applied to the top surface of the exemplary upper plunger component (which is after a rotational force has been applied to the upper plunger component in accordance with what has been described above).
[0359]
[0396] 28 , the central ring portion 2802 and the intermediate ring portion 2804 may move vertically downward, and the vent bluff ring member 2806 may enter the gap between the central ring portion 2802 and the intermediate ring portion 2804. As the vent bluff ring member 2806 enters the gap between the central ring portion 2802 and the intermediate ring portion 2804, the sealing ridge 2808 on the inner surface of the intermediate ring portion 2804 may contact the outer surface of the vent bluff ring member 2806. When the sealing ridge 2808 moves past the opening 2810 on the vent bluff ring member 2806, the sealing ridge 2808 blocks and seals the vent channel so that the sample can no longer exit through the vent channel. In some embodiments, the central ring portion 2802 is longer than the intermediate ring portion 2804 so that when the central ring portion 2802 and the intermediate ring portion 2804 move vertically downward, the central ring portion 2802 pushes air between the bent bluff ring member 2806 and the pipe member 2820 through the opening 2810.
[0360]
[0397] 29A and 29B each illustrate an exemplary cross-sectional view of at least a portion of an exemplary aerosol collection device 2900 according to an example of the present disclosure.
[0361]
[0398] 29A and 29B, the exemplary aerosol collection device 2900 includes at least a lower plunger component 2901. As shown, a bottom surface of the lower plunger component 2901 is in contact with a filter component 2903.
[0362]
[0399] In some embodiments, the exemplary aerosol collection device 2900 includes an upper plunger component 2905 in contact with an upper surface of a lower plunger component 2901 (e.g., in the second configuration as described above). As such, in response to receiving a vertical force exerted on the upper surface of the upper plunger component 2905, the upper plunger component 2905 is configured to transmit the vertical force to the lower plunger component 2901, causing vertical movement of the lower plunger component 2901. In some embodiments, the vertical movement of the lower plunger component 2901 causes the filter component 2903 to be squeezed such that the buffer solution containing the collected aerosol is expelled from the filter component 2903.
[0363]
[0400] Further, in some embodiments, the upper plunger component 2905 is configured to transmit a vertical force to the tube component 2907 because at least an upper portion of the pipe member 2911 of the tube component 2907 is received within the central annulus portion 2913 of the upper plunger component 2905. The vertical force causes the tube component 2907 to move downward, causing the valve component 2909 to come into contact with the middle portion of the tube component 2907, thereby sealing the flow channel. Furthermore, as described above in connection with at least FIG. 28 , the vertical force causes the sealing ridge 2915 to move downward along the vent bluff annulus member 2917 of the tube component 2907, thereby sealing the vent channel.
[0364]
[0401] As such, in some embodiments, after a vertically downward force is applied to the top surface of the upper plunger component 2905 when the upper plunger component 2905 is in the second configuration, both the flow channel and the vent channel are sealed, increasing the internal pressure to extract the buffer solution from the aerosol collection device 2900. In some embodiments, during operation, the cap member is secured back to the exemplary aerosol collection device (e.g., secured onto the upper plunger component 2905) after a user provides a sample to the aerosol collection device. In such embodiments, to apply a vertically downward force to the top surface of the upper plunger component 2905, a user must remove the cap member from the exemplary aerosol collection device (e.g., from the upper plunger component 2905) so that the vertically downward force can be applied to the upper plunger component.
[0365]
[0402] Referring now to FIG. 30, a portion of an exemplary cross-sectional view of an exemplary aerosol collection device 3020 is shown.
[0366]
[0403] In various embodiments, the exemplary aerosol collection device 3020 can include a device body portion 3026 that includes an upper plunger component 3007, where one or more of the sample transfer adapters (e.g., a mask component, a sampling tunnel, and / or a sampling hood, etc.) can be removably secured to the upper plunger component 3007. In the example shown in FIG. 30 , the exemplary aerosol collection device 3020 can include the upper plunger component 3007 having a central bore 3011 embodied as an orifice extending through a generally central portion of the upper plunger component 3007. In some embodiments, the central bore 3011 can allow sample to enter the exemplary aerosol collection device 3020 through a flow channel. In various embodiments, the central bore 3011 is configured to receive at least a portion of a sample transfer adapter (e.g., a mask component, a sampling tunnel, and / or a sampling hood, etc.) to at least partially secure the sample transfer adapter to the device body portion 3026 of the aerosol collection device 3020. For example, in some embodiments, the sampling channel of the exemplary sample transfer adapter may be mechanically secured within the central bore 3011 of the exemplary upper plunger component 3007 via various means, as described herein, such that an air flow path extending from the sample outlet portion of the sampling channel to the central bore 3011 of the aerosol collection device 3020 may remain at least substantially unobstructed, as described herein. For example, a user may breathe into the sample transfer adapter (e.g., a mask component and sample (e.g., exhaled air) may pass both through the sample transfer adapter (e.g., through the sample outlet portion of the sampling channel) and the central bore 3011 of the flow channel.
[0367]
[0404] In various embodiments, the exemplary aerosol collection device 3020 can be configured so that a sample received by the upper plunger component 3007 can flow through the central bore 3011 to the central passages 3017A and 3017B of the device body portion 3026 as part of a flow channel. As described in more detail herein, in some embodiments, the central passages 3017A and 3017B of the device body portion 3026 can include a tubular channel extending at least substantially along the central axis of the device body portion 3026 that allows air to pass therethrough. For example, in various embodiments, the central passages 3017A and 3017B can define an air flow path extending between the upper plunger component 3007 and a bottom portion (e.g., a valve support collar) of the aerosol collection device 3020 such that a sample of air received by the device body 3026 via the central bore 3011 can be directed to the bottom portion of the aerosol collection device 3020 (e.g., toward a bottom surface of an interior portion of the device body 3026). In various embodiments, the bottom portion of the aerosol collection device 3020 (e.g., in the valve support collar) can be embodied as a breath analyzer mixing chamber.
[0368]
[0405] For example, in various embodiments, the mixing chamber of the exemplary aerosol collection device 3020 can include at least a portion of the aerosol collection device 3020 components (including at least the valve support ring member 3024, the sample distribution ring member 3023, and / or the filter component 3005, etc.) configured to enable the dynamic aerosol capture and / or collected sample extraction functionality of the exemplary aerosol collection device 3020. As described in further detail herein, the filter component 3005 configured to receive an air sample and capture at least a portion of the aerosol present in the sample can be disposed in a bottom portion (e.g., the mixing chamber) of the aerosol collection device 3020.
[0369]
[0406] In various embodiments, the air sample flowing along the central passage 3017B can pass through a gap between the valve component 3018 and the tube component 3050 and then into the valve support ring member 3024, which defines a terminal end of the central passage 3017B disposed in a bottom portion of the device body. In various embodiments, the valve support ring member 3024 can include a tubular channel disposed in an at least substantially coaxial configuration with the central passage 3017B along a central axis of the device body 3026. The valve support ring member 3024 can be configured to accept the air sample flowing along a flow channel defined at least in part by the central passage 3017B. In various embodiments, the exemplary valve support ring member 3024 can include one or more outlets distributed annularly around an end portion of its substantially cylindrical sidewall. For example, as illustrated in Figures 30 through 31B, in various embodiments, one or more outlet portions of the central passage can include multiple outlet portions collectively configured to dispense a sample received by the valve support ring member 3024 in at least a substantially uniform annular distribution.
[0370]
[0407] In various embodiments, the aerosol collection device 3020 can be configured such that sample dispensed from one or more outlets 3031 of the valve support ring member 3024 can be provided to the sample distribution ring member 3023. In various embodiments, the sample distribution ring member 3023 can be configured to further promote at least a substantially uniform annular distribution of the air sample as the sample moves radially outward toward the filter element 3005 of the aerosol collection device 3020. As described herein, the sample distribution ring member 3023 can promote at least a substantially uniform annular distribution of the sample throughout the filter element 3005 positioned annularly around the exterior of the sample distribution ring member 3023. In various embodiments, the sample distribution ring member 3023 can include a sample distribution ring member sidewall 3025. The sample distribution ring member sidewall 3025 of the sample distribution ring member 3023 can at least partially define an internal chamber cavity embodied as an interior volume within a hollow central portion of the sample distribution ring member sidewall 3025. In various embodiments, the sample distribution ring member 3023 can be positioned within the device body 3026 such that the central axis of the sample distribution ring member sidewall 3025 is at least substantially coaxial with the valve support ring member 3024, e.g., in a position centered about the central axis of the device body 3026. In such an exemplary configuration, the sample distribution ring member sidewall 3025 can be at least partially defined by an inner diameter at least substantially larger than the outer diameter of the valve support ring member 3024, such that the sample distribution ring member sidewall 3025 can surround at least a portion of the valve support ring member 3024. For example, the aerosol collection device 3020 may be configured so that the inner surface of the sample distribution ring member side wall portion 3025 is separated from the outer surface of the valve support ring member 3024 by a gap defined radially relative to the central axis of the two coaxial components.For example, in various embodiments, the radial gap between the sample distribution ring member sidewall 3025 and the exterior of the valve support ring member 3024 can include an at least substantially uniform distance throughout at least a portion of the length of the sample distribution ring member sidewall 3025 (e.g., measured longitudinally parallel to the central axis of the sample distribution ring member sidewall 3025). By way of example, the radial gap between the sample distribution ring member sidewall 3025 and the exterior of the valve support ring member 3024 can be defined by an at least substantially uniform radial distance throughout at least an annular portion of the sample distribution ring member sidewall 3025 (e.g., measured circularly around the central axis of the sample distribution ring member sidewall 3025).
[0371]
[0408] In various embodiments, the radial gap between the sample distribution ring member sidewall 3025 and the exterior of the valve support ring member 3024 can define an opening 3019, which extends annularly around the entire interior surface of the sample distribution ring member sidewall 3025. In various embodiments, the opening 3019 can be fluidly connected to one or more outlets 3031 of the valve support ring member 3024 such that an air sample dispensed from the one or more outlets 3031 can be distributed throughout the opening 3019. For example, the opening 3019 can define at least a portion of an internal chamber cavity of the sample distribution ring member 3023. In such an exemplary configuration, the air sample, upon being dispensed from the one or more outlets 3031, can initially be retained within the internal chamber cavity of the sample distribution ring member 3023.
[0372]
[0409] In various embodiments, the aerosol collection device 3020 can include one or more filter components configured to capture at least a portion of aerosols present in a sample received by the aerosol collection device 3020. For example, in various embodiments, the filter component can include an at least substantially porous material such that a sample containing one or more aerosols can be received by and retrained by the filter component. In some embodiments, the one or more aerosols can migrate along at least a portion of the filter component, as described herein. In various embodiments, the aerosol collection device 3020 can be configured such that the cylindrically shaped filter component 3005 can be positioned at least substantially adjacent to the outer surface of the sample distribution ring member sidewall 3025. For example, at least a portion of the inner surface of the cylindrically shaped filter component 3005 can define a receiving surface, which can be positioned against the outer surface of the sample distribution ring member sidewall 3025 such that the filter component 3005 is physically engaged with the sample distribution ring member sidewall 3025.
[0373]
[0410] Further, in various embodiments, as shown in the particular exemplary aerosol collection device illustrated in FIG. 31B , the aerosol collection device 3020 (e.g., the device body 3026) can include a filter support body member 3127, which is embodied as a material recess, and in which at least a portion of the cylindrically-shaped filter component 3005 can be disposed. For example, the filter support body member 3127 can be positioned directly adjacent to an outer surface of the sample distribution ring member sidewall 3025, extending around at least a portion of the periphery of the sample distribution ring member sidewall 3025. The filter support body member 3127 can be configured to receive at least a portion of the cylindrically-shaped filter component 3005 and further configured to at least partially secure the filter component 3005 relative to the sample distribution ring member 3023, such that the filter component 3005 is disposed at least substantially adjacent to the outer surface of the sample distribution ring member sidewall 3025.
[0374]
[0411] As described herein, the sample distribution ring member 3023 of the exemplary aerosol collection device 3020 can be configured to promote at least substantially uniform annular distribution of the air sample to the filter component 3005 positioned at least substantially adjacent thereto. As described herein, in various embodiments, the filter component 3005 can include a wetted configuration, in which the filter component 3005 can absorb at least a portion of the buffer solution released from one or more capsule components, as described in detail herein. In some embodiments, a predetermined volume of buffer solution is disposed throughout an interior portion of the filter component 3005 (e.g., a side of the filter component 3005 near the sample distribution ring member) and / or an exterior portion of the filter component 3005 (e.g., a side of the filter component 3005 opposite the interior portion near the vent channel).
[0375]
[0412] 31A and 31B, the sample distribution ring sidewall 3025 can include a plurality of holes 3030. For example, after a user provides a sample to the exemplary aerosol collection device 3020 (e.g., by blowing into the exemplary aerosol collection device 3020), the sample (e.g., exhaled breath) can form one or more bubbles in the buffer solution (e.g., as the sample flows through one or more outlets 3031). In some embodiments, upon receiving the sample from adjacent holes of the plurality of holes 3030, the filter component 3005 can be configured such that bubbles form in and / or migrate to the predetermined volume of solution and capture the sample (e.g., including one or more aerosols present in the sample). For example, after a user provides a sample to the exemplary aerosol collection device 3020 (e.g., by blowing into the exemplary aerosol collection device 3020), the sample (e.g., exhaled breath) can flow through one or more outlets 3031 in the valve support ring member 3024 and enter the open ring 3019. The sample can further flow through a plurality of holes 3030 in the sample distribution ring member side wall 3025 and form one or more bubbles.
[0376]
[0413] In some embodiments, one or more aerosols in the sample may be disposed within bubbles that engage with the solution within the filter element 3005. For example, the filter element 3005 may be configured to allow bubbles therein to flow (e.g., ascend) vertically through an interior portion of the body of the filter element 3005, while also being configured to capture one or more aerosols present within the bubbles within the filter element. In some embodiments, the filter element 3005 may destroy bubbles that exceed a size threshold, thereby reducing the likelihood that aerosol droplets can pass through the filter element 3005. In some embodiments, the filter element 3005 may be configured to increase the surface-to-volume ratio of bubbles disposed therein. Thus, in such an exemplary situation, the filter element 3005 may be configured to increase the mass transfer rate associated with the aerosols present within the bubbles, such that the aerosols may be separated from the bubbles and captured within a predetermined volume of liquid present within the filter element. As described herein, the buffer solution distributed throughout the filter element 3005 can cause the captured aerosol to be at least substantially retained in a sample liquid that contains at least a portion of the biological attributes of the aerosol as originally received.
[0377]
[0414] In various embodiments, the sample distribution ring member 3023 can include one or more sample distribution members configured to promote at least substantially uniform annular distribution of the sample throughout the filter element 3005. For example, an exemplary sample distribution ring member can include one or more holes 3030 extending through the sample distribution ring member sidewall 3025 (e.g., between the inner and outer surfaces of the sample distribution ring member sidewall 3025) and fluidly connecting the open ring 3019 to the filter element 3005. More specifically, the one or more holes 3030 extending through the sample distribution ring member sidewall 3025 can provide a fluid connection between the open ring 3019 and the filter element 3005, such that at least a portion of the sample present in the open ring 3019 can flow through an orifice in the sample distribution ring member sidewall 3025 and engage a portion of the receiving surface of the filter element 3005 positioned directly adjacent to the orifice. By way of example, in various embodiments, the one or more holes 3030 can provide only a fluid connection between the sample distribution ring member 3023 and the adjacent filter element 3005, such that at least substantially all of the sample provided to the sample distribution ring member 3023 (e.g., sample received in the open ring 3019) can be dispensed from the sample distribution ring member 3023 and delivered to the filter element 3005 via the one or more holes 3030.
[0378]
[0415] 30-31B, in various embodiments, the one or more orifices of the exemplary sample distribution ring member 3023 can include multiple orifices embodied as multiple holes 3030 distributed throughout the sample distribution ring member sidewall 3025. By way of non-limiting example, in various embodiments, the multiple holes 3030 can include at least substantially between 8 and 40 holes (e.g., between 16 and 24 holes) distributed throughout the sample distribution ring member sidewall 3025.
[0379]
[0416] In various embodiments, one or more of the holes of the plurality of holes 3030 can embody a physical configuration that is either the same as or different from the physical configuration of one or more other holes of the plurality of holes 3030. For example, the physical configuration of a hole as described herein can be defined at least in part by the surface area, shape, angular orientation in which the hole extends through the thickness of the sample distribution ring member side wall 3025 (e.g., a linear orientation perpendicular to the central axis of the device body 3026 and / or an orientation defining an angle away from a horizontal plane, etc.). In various embodiments, the surface area of one or more holes of the plurality of holes 3030 can be configured to enable a particular mass flow rate through the sample distribution ring member side wall 3025. For example, in various embodiments, the cumulative surface area of each of the plurality of holes 3030 distributed around the sample distribution ring member sidewall 3025 can comprise at least substantially between 20% and 100% (e.g., between 50% and 100%) of the total surface area of the sample inlet portion (e.g., central bore 3011) of the aerosol collection device 3020. Further, by way of example, in various embodiments, the cumulative surface area of each of the plurality of holes 3030 distributed around the sample distribution ring member sidewall 3025 can be at least substantially equal to the surface area of the central bore 3011 of the exemplary aerosol collection device 3020. In various embodiments, the cumulative surface area of one or more holes of the plurality of holes 3030 can be configured to allow a particular pressure to be dropped across the exemplary sample distribution ring member 3023. In various embodiments, one or more of the holes of the plurality of holes 3030 can include a uniform cross-sectional area throughout the thickness of the sample distribution ring member side wall 3025 (e.g., between the inner and outer surfaces of the sample distribution ring member side wall 3025). Furthermore, in various embodiments, one or more of the holes of the plurality of holes 3030 can include a variable cross-sectional area at one or more locations along the thickness of the sample distribution ring member side wall 3025.
[0380]
[0417] Further, in various embodiments, one or more of the holes of the plurality of holes 3030 can include a uniform cross-sectional area throughout the thickness of the sample distribution ring member side wall 3025 (e.g., between the inner and outer surfaces of the sample distribution ring member side wall 3025). Further, in various embodiments, one or more of the holes of the plurality of holes 3030 can include a variable cross-sectional area at one or more locations along the thickness of the sample distribution ring member side wall 3025.
[0381]
[0418] In various embodiments, the sample distribution ring member sidewall 3025 can be defined at least in part by the sidewall length as measured in a direction parallel to the central axis of the device body 3026. For example, one or more of the plurality of holes 3030 can be positioned along the length of the sample distribution ring member sidewall 3025 at a location defined at least in part by the vertical distance between each hole and the top surface of the adjacent filter element 3005. For example, the position of a hole of the plurality of holes 3030 relative to the length of the sample distribution ring member sidewall 3025 can define the vertical distance along which sample dispensed through a hole into the adjacent filter element 3005 must travel within the body of the filter element to reach the upper boundary of the filter element. In various embodiments, one or more of the plurality of holes 3030 disposed in the sample distribution ring member side wall 3025 can be positioned along the sample distribution ring member side wall 3025 such that the distance between the one or more holes and the top surface of the sample distribution ring member side wall 3025, as measured vertically, can be at least substantially between 50% and 100% (e.g., between 50% and 75%) of the total length of the sample distribution ring member side wall 3025. That is, for example, in various embodiments, one or more of the plurality of holes 3030 disposed in the sample distribution ring member side wall 3025 can be positioned around the lower half of the sample distribution ring member side wall 3025 (e.g., the half of the sample distribution ring member side wall 3025 positioned relatively close to the bottom surface of the device body 3026, as measured vertically along the length of the sample distribution ring member side wall 3025).
[0382]
[0419] In various embodiments, the position of one or more of the plurality of holes relative to the total length of the sample distribution ring member side wall portion 3025 and / or filter component 3005 can be either the same as or different from the position of one or more other holes of the plurality of holes 3030.
[0383]
[0420] As described in more detail herein, in some embodiments, the aerosol may be captured in the filter component 3005, and air may be removed from the aerosol through the filter component 3005 in the form of bubbles. The air separated from the aerosol may then enter the breath analyzer chamber 3021. Referring to the exemplary aerosol collection device 3020 shown in FIG. 30 , the breath analyzer chamber 3021 may be positioned above the filter component 3005, thus allowing air to escape from the filter component 3005 into the breath analyzer chamber 3021.
[0384]
[0421] As further described herein, in some embodiments, the aerosol-depleted predetermined volume of air in the breath analyzer chamber 3021 may be further passed through one or more vent channels 3027 configured to dispense at least a portion of the predetermined volume of air in the aerosol collection device 3020 into the ambient environment. For example, the one or more vent channels 3027 may include one or more orifices positioned about the external breath analyzer surface of the upper plunger component 3007 and may be configured to provide fluid communication between the breath analyzer chamber 3021 and the ambient environment such that the aerosol-depleted predetermined volume of air in the breath analyzer chamber 3021 may be dispensed into the ambient environment via the one or more orifices in the upper plunger component 3007.
[0385]
[0422] In various embodiments, the exemplary aerosol collection device can include a device body 3026 that includes an aerosol collection device housing configured to store various components of the exemplary aerosol collection device 3020 within an interior portion of the housing. As described herein, the aerosol collection device 3020 can be configured to accept an air sample (e.g., from a sample transfer adapter) through the upper plunger component 3007 and deliver the accepted sample along an air flow path or flow channel throughout various components (e.g., filter component 3005 and / or sample distribution ring 3023, etc.) disposed within the housing of the device body 3026 to capture at least a portion of the aerosol present in the sample upon acceptance into the filter component 3005. In various embodiments, the aerosol collection device 3020 can be configured to accept a single air sample provided continuously to the aerosol collection device 3020 over a predetermined length of time or multiple air samples provided sequentially to the aerosol collection device 3020 over time. In such an exemplary situation, an air sample provided to the aerosol collection device 3020 over time may be repeatedly passed through a filter component 3005 housed within the device body 3226, as described herein, such that aerosols captured by the filter component 3005 over time may accumulate within the filter component 3005. In such an exemplary configuration, the accumulated aerosols disposed within the filter component may affect one or more physical properties of the filter component 3005 and / or a volume of buffer solution present within the filter component 3005.For example, in various embodiments, one or more physical attributes, such as weight, volume, particle concentration, and / or color, of the filter element 3005 and / or of the volume of buffer solution therein may change over time as the amount of aerosol captured within the wetted filter element 3005 (e.g., the filter element 3005 having the volume of buffer solution disposed therein) increases.
[0386]
[0423] In various embodiments, the exemplary aerosol collection device 3020 can include means for monitoring one or more characteristics of the wetted filter component 3005 disposed within the device body 3226 over time without interrupting operation of the aerosol collection device 3220. Referring now to FIG. 32A , a portion of an exemplary perspective cross-sectional view of the exemplary aerosol collection device 3220 is depicted. As shown, various components of the exemplary aerosol collection device 3220 are disposed within the housing of the device body 3226, such as, for example, the central passage 3217B, the valve support ring member 3224, the sample distribution ring member 3223, and the filter component 3205 configured according to various embodiments described herein. By way of example, the housing (e.g., the reservoir component) of the device body 3226 can include an observation orifice 3240 positioned around at least a portion of the exterior surface of the device body 3226 and extending through a thickness of the device body 3226. In various embodiments, the observation orifice 3240 can facilitate a line of sight between a vantage point in the ambient environment external to the device body 3226 and one or more aerosol collection device 3220 components housed within the device body 3226. For example, the observation orifice 3240 can be provided in a surface positioned at least substantially adjacent to one or more aerosol collection device 3220 components within the device body 3226 (for which visibility from an external vantage point is desired). By way of example, the exemplary aerosol collection device 3220 depicted in FIGS. 32A and 32B can include an observation orifice 3240 configured to provide a line of sight from a remote vantage point in the ambient environment to at least a portion of the filter component 3205 positioned adjacent the observation orifice 3240.For example, the exemplary observation orifice 3240 can embody a viewing window configured to allow a user to view at least a portion of the filter component 3205 disposed within the housing of the device body 3226 without requiring disassembly of the aerosol collection device 3220 and / or interruption of operation of the aerosol collection device 3220. In various embodiments, the observation orifice 3240 can include at least one transparent member (e.g., clear glass and / or clear plastic, etc.) that covers a surface area of the observation orifice 3240 and is configured to facilitate visibility of the filter component 3205 while preventing undue air leakage through the observation orifice 3240 and / or contamination of the aerosol collection device 3220. Additionally, in various embodiments, at least one transparent member of the observation orifice 3240 can be configured to visually magnify at least a portion of one or more internal breath analyzer components (e.g., the filter component 3205) toward which the observation orifice 3240 is oriented.

[0424] As described in more detail herein, the aerosol collection device can be configured to allow one or more samples of air containing a plurality of aerosols to pass through the wetted filter element 3205, the wetted filter element 3205 being configured to capture at least a portion of the aerosols in the sample passing therethrough, such that the captured aerosols become embedded within the thickness of the filter element 3205. Over time, the captured aerosols can accumulate within the thickness of the filter element 3205, allowing the aerosols to react with a buffer solution dispersed throughout the wetted filter element 3205. In various embodiments, the accumulated aerosols that become trapped within the filter element 3205 thickness can cause the physical appearance of the filter element 3205 to change, at least in part, due to, for example, the presence or increased concentration of aerosols present within the filter element 3205 and / or a chemical reaction between one or more of the accumulated aerosols and the buffer solution, etc. For example, in such an exemplary situation, one or more aspects of the physical appearance of the filter component 3205 (e.g., color, transparency, texture, and / or uniformity, etc.) may undergo a noticeable change, which may be visible to a user observing the filter component through the observation orifice 3240.
