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. A method for assembling an aerosol collection device comprising:
providing a vessel component comprising at least a valve support annulus element and a sample distribution annulus element;
inserting a filter component between the sample distribution annulus element and at least one of a filter support body element or a capsule extraction body element of the vessel component; and
positioning a valve component on the valve support annulus element;
wherein the vessel component comprises at least two vertical ridge elements disposed on an inner lateral surface of the vessel component.

2. The method of claim 1 , wherein the sample distribution annulus element is positioned on an inner bottom surface of the vessel component, wherein the valve support annulus element is positioned within the sample distribution annulus element, wherein the sample distribution annulus element comprises one or more sample distribution elements configured to distribute at least a portion of a sample to a respective filter portion of a plurality of distributed filter portions defined throughout the filter component.

3. The method of claim 2 , wherein the vessel component comprises at least one capsule extraction body element positioned on the inner bottom surface of the vessel component and radially outward from the sample distribution annulus element.

4. The method of claim 1 , wherein the valve support annulus element comprises a plurality of supporting beams, wherein the valve component is supported by the plurality of supporting beams.

5. The method according to claim 1 , further comprising:
securing a tube component to the sample distribution annulus element; and
positioning at least one capsule component on a top surface of the capsule extraction body element.

6. The method of claim 5 , wherein the at least one capsule component comprises a first capsule component storing a first buffer solution and a second capsule component storing a second buffer solution.

7. The method of claim 5 , wherein the tube component comprises a pipe element having a top portion and a bottom portion, wherein the top portion is connected to the bottom portion, forming at least a portion of a flow channel for a fluid substance.

8. The method of claim 7 , wherein the valve component is positioned between a plurality of supporting beams of the valve support annulus element and an inner surface of a middle portion of the pipe element of the tube component.

9. The method of claim 5 , wherein the tube component comprises a first notch, wherein the sample distribution annulus element comprises a second notch.

10. The method of claim 9 , wherein the tube component is secured to the sample distribution annulus element through a slide interference fit between the first notch and the second notch.

11. The method of claim 1 , wherein the at least one capsule component is secured between the at least two vertical ridge elements of the vessel component.

12. The method of claim 5 , wherein the at least one capsule component stores a buffer solution.

13. The method of claim 12 , wherein the at least one capsule component comprises:
a holder element defining a cavity having an opening on a bottom surface of the at least one capsule component and storing the buffer solution, and
a cap element hermetically sealing the opening of the holder element.

14. The method of claim 13 , wherein the cap element is positioned on the top surface of the capsule extraction body element.

15. The method according to claim 5 , further comprising:
positioning a lower plunger component on a top surface of the filter component; and
securing an upper plunger component on a top surface of the at least one capsule component.

16. The method of claim 15 , wherein the lower plunger component comprises:
a plunger annulus element having an outer lateral surface; and
a plurality of plunger support wings disposed on the outer lateral surface, wherein each of the plurality of plunger support wings comprises a bottom portion and a lateral portion.

17. The method of claim 15 , further comprising:
securing a cap component on the upper plunger component.

18. The method of claim 1 , further comprising:
providing a sample transfer adapter, wherein the sample transfer adapter comprises at least one of a sampling tunnel or a mask component.

19. The method of claim 1 , further comprising:
providing an extraction cartridge configured to extract a volume of a sample liquid from within the aerosol collection device.
