Abstract

Methods, apparatuses, and systems associated with aerosol collection devices (such as, but not limited to, breath-aerosol collector devices, breathalyzers) are provided. An example aerosol collection device includes a sample transfer adapter configured to receive a sample and a device body connected to the sample transfer adapter. In some examples, the device body defines a flow channel that guides the sample to a filter component, and the filter component contains a buffer solution.

First claim

The invention claimed is:

1. An aerosol collection device comprising: a housing comprising one or more exterior surfaces and defining a device body;
a filter component disposed within the device body; a first observation orifice defining a line of sight to at least a portion of the filter component, the line of sight extending through at least a portion of the one or more exterior surfaces of the housing, wherein the first observation orifice corresponds to a user viewing window for viewing at least the portion of the filter component;
an extraction cartridge configured to extract a volume of a sample from within the device body, wherein the extraction cartridge comprises an extraction plunger, wherein said extraction plunger is disposed within a cylindrical cartridge body of the extraction cartridge, and wherein said extraction plunger is configured to generate a pressure differential based at least in part on a displacement along a central axis of the cylindrical cartridge body; and a second observation orifice defining a line of sight to the extraction plunger.

2. The aerosol collection device of claim 1 , further comprising at least one transparent element configured to cover a surface area of the observation orifice.

3. The aerosol collection device of claim 2 , wherein the at least one transparent element comprises a magnifying element configured to visually magnify the at least the portion of the filter component positioned within the line of sight.

4. The aerosol collection device of claim 1 , further comprising a sampling tunnel configured to receive a sample, wherein the device body is connected to the sampling tunnel.

5. The aerosol collection device of claim 4 , wherein the device body further comprises hermetically sealed containers, wherein the hermetically sealed containers contain a buffer solution.

6. The aerosol collection device of claim 1 , further comprising:
a capsule extraction body element, and
at least one capsule component storing buffer solution and positioned on the capsule extraction body element.

7. The aerosol collection device of claim 1 , further comprising a sample transfer adapter configured to receive a sample, wherein the device body is connected to the sample transfer adapter.

8. The aerosol collection device of claim 7 , wherein the sample transfer adapter comprises a sampling channel configured to deliver the sample to a sample inlet of the device body.

9. The aerosol collection device of claim 7 , wherein the sample transfer adapter further comprises an attachment element configured to connect the sample transfer adapter to the device body.

10. The aerosol collection device of claim 8 , wherein the sample transfer adapter further comprises one or more adapter ventilation elements defining at least a portion of a dispense flow path to facilitate delivery of a dispensed sample emitted from the device body to an ambient environment.

11. The aerosol collection device of claim 1 , further comprising a sample distribution annulus element fluidly connected to the filter component, the sample distribution annulus element being configured to receive the sample and deliver at least a portion of the sample to one or more portions of the filter component.

12. The aerosol collection device of claim 11 , wherein the sample distribution annulus element comprises one or more sample distribution elements configured to facilitate distribution of the sample throughout the filter component.

13. The aerosol collection device of claim 12 , wherein each of the one or more sample distribution elements is configured to distribute at least the portion of a sample to a respective filter portion of a plurality of distributed filter portions defined throughout the filter component.

14. The aerosol collection device of claim 12 , wherein the filter component comprises an at least substantially cylindrical configuration defined at least in part by a substantially cylindrical interior filter surface, wherein the sample distribution annulus element comprises a sample distribution annulus element sidewall, wherein the device body is configured such that an outer surface of the sample distribution annulus element is positioned at least substantially adjacent the substantially cylindrical interior filter surface.

15. The aerosol collection device of claim 14 , wherein the one or more sample distribution elements comprises a plurality of orifices extending through the sample distribution annulus element sidewall of the sample distribution annulus element, each of the plurality of orifices defining a fluid connection between the sample distribution annulus element and the filter component.

16. The aerosol collection device of claim 1 , wherein the sample comprises a buffer solution and an aerosol.

17. The aerosol collection device of claim 1 , wherein the device body further comprises a sample liquid extraction outlet comprising an opening extending through a bottom surface of the device body along a central axis of the device body.

18. The aerosol collection device of claim 17 , wherein the extraction cartridge comprises one or more attachment means configured for attaching the extraction cartridge to the sample liquid extraction outlet.

19. The aerosol collection device of claim 1 , wherein the device body comprises a groove component disposed on a bottom surface of the device body.
