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:
an upper plunger component comprising a central annulus portion and an intermedial annulus portion, wherein the central annulus portion is disposed within the intermedial annulus portion, forming a gap between the central annulus portion and the intermedial annulus portion, wherein a sealing ridge is disposed on an inner surface of the intermedial annulus portion; and
a tube component comprising a vent bluff annulus element, wherein at least a portion of the central annulus portion is positioned within and in contact with the vent bluff annulus element.

2. The aerosol collection device of claim 1 , wherein the upper plunger component comprises a plunger head element defining a central bore.

3. The aerosol collection device of claim 2 , wherein the tube component comprises a pipe element connected to the central bore and forming a portion of a flow channel for receiving a sample.

4. The aerosol collection device of claim 1 , further comprising a sample transfer adapter configured to deliver a sample to a sample inlet of the aerosol collection device, wherein the sample transfer adapter comprises at least one of a sampling tunnel or a mask component.

5. The aerosol collection device of claim 3 , wherein a top portion of the pipe element of the tube component is positioned within the central annulus portion of the upper plunger component.

6. The aerosol collection device of claim 1 , wherein a gap between a top surface of the vent bluff annulus element and a bottom surface of the intermedial annulus portion define a portion of a vent channel for discharging a sample.

7. The aerosol collection device of claim 1 , wherein the central annulus portion and the intermedial annulus portion define a portion of a vent channel for discharging a sample.

8. The aerosol collection device of claim 1 , wherein the vent bluff annulus element comprises at least one opening defining a portion of a vent channel for discharging a sample.

9. The aerosol collection device of claim 1 , wherein, when a vertical force is exerted on a top surface of the upper plunger component, at least a portion of the vent bluff annulus element of the tube component enters into the gap between the central annulus portion of the upper plunger component and the intermedial annulus portion of the upper plunger component.

10. The aerosol collection device of claim 9 , wherein, when the vertical force is exerted on the top surface of the upper plunger component, the sealing ridge moves past an opening on the vent bluff annulus element and blocks a vent channel.

11. The aerosol collection device of claim 1 , further comprising:
a lower plunger component comprising a plurality of plunger support wings, wherein each of the plurality of plunger support wings is positioned between two of a plurality of capsule components, wherein the plurality of capsule components comprises a first capsule component storing a first buffer solution and a second capsule component storing a second buffer solution.

12. The aerosol collection device of claim 11 , wherein the lower plunger component and the upper plunger component are housed within a vessel component having at least one vertical lock ridge element and at least one vertical stop ridge element disposed on an inner lateral surface of the vessel component.

13. The aerosol collection device of claim 12 , wherein the upper plunger component is configured to translate from a first configuration to a second configuration by a rotational force.

14. The aerosol collection device of claim 13 , wherein the upper plunger component comprises at least one leg portion, wherein:
in the first configuration, a bottom surface of the at least one leg portion is in contact with a top surface of each of the plurality of capsule components; and
in the second configuration, the bottom surface of the at least one leg portion is in contact with a top surface of each of the plurality of plunger support wings.

15. The aerosol collection device of claim 14 , the rotational force causes at least a portion of the at least one leg portion to rotate past the at least one vertical lock ridge element and stop at the at least one vertical stop ridge element.

16. The aerosol collection device of claim 12 , wherein a bottom surface of the lower plunger component is in contact with a filter component, wherein the upper plunger component is in contact with a top surface of the lower plunger component.

17. The aerosol collection device of claim 16 , wherein in response receiving a vertical force exerted on a top surface of the upper plunger component, the upper plunger component is configured to transfer the vertical force to the lower plunger component and cause a vertical movement of the lower plunger component.

18. The aerosol collection device of claim 16 , wherein a sample distribution annulus element is fluidly connected to the filter component, wherein the sample distribution annulus element comprises one or more sample distribution elements configured to distribute at least a portion of the sample to a respective filter portion of a plurality of distributed filter portions defined throughout the filter component.

19. The aerosol collection device of claim 1 , further comprising:
an extraction cartridge attached to a sample liquid extraction outlet of the aerosol collection device via one or more attachment means defined at least in part by the extraction cartridge.
