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 sample transfer adapter configured to receive a sample; and
a device body connected to the sample transfer adapter, wherein the device body defines a flow channel guiding the sample to a filter component, wherein the filter component contains a buffer solution, wherein the device body comprises:
a vessel component comprising at least one capsule extraction body element, and
at least one capsule component positioned on a top surface of the at least one capsule extraction body element,

wherein the vessel component comprises at least two vertical ridge elements disposed on an inner lateral surface of the vessel component, wherein at least a portion of each of the at least one capsule component is positioned between the at least two vertical ridge elements.

2. The aerosol collection device of claim 1 , wherein the vessel component comprises a sample distribution annulus element, wherein the buffer solution is contained in at least one of a first side of the filter component adjacent to the sample distribution annulus element or a second side of the filter component opposite to the first side.

3. The aerosol collection device of claim 1 , wherein the sample transfer adapter is a sampling tunnel.

4. The aerosol collection device of claim 1 , wherein the sample transfer adapter is a mask component.

5. The aerosol collection device of claim 1 further comprising an extraction cartridge.

6. The aerosol collection device of claim 5 , wherein the device body comprises a sample liquid extraction outlet, wherein the extraction cartridge comprises one or more puncturing elements configured to at least partially extend into the sample liquid extraction outlet.

7. The aerosol collection device of claim 1 , wherein the device body comprises:
an upper plunger component positioned on a top surface of the at least one capsule component.

8. The aerosol collection device of claim 7 , wherein the at least one capsule component stores the buffer solution.

9. The aerosol collection device of claim 8 , wherein each of the at least one capsule component comprises a holder element and a cap element, wherein the buffer solution is hermetically sealed in the holder element by the cap element.

10. The aerosol collection device of claim 9 , wherein the at least one capsule extraction body element comprises a protrusion positioned on the top surface of the at least one capsule extraction body element, wherein the cap element is positioned on top of the protrusion.

11. The aerosol collection device of claim 9 , wherein, in response to receiving a vertically downward force exerted on a top surface of the upper plunger component, the upper plunger component is configured to transfer the vertically downward force to the at least one capsule component and causing a vertical movement of the at least one capsule component.

12. The aerosol collection device of claim 11 , wherein the vertical movement of the at least one capsule component causes the at least one capsule extraction body element to break the cap element of each of the at least one capsule component.

13. The aerosol collection device of claim 12 , wherein, subsequent to the cap element being broken, the buffer solution flows on the filter component.

14. The aerosol collection device of claim 7 , wherein the vessel component further comprises:
a sample distribution annulus element comprising a plurality of holes, and
a valve support annulus element disposed within the sample distribution annulus element.

15. The aerosol collection device of claim 14 , wherein the at least one capsule extraction body element is positioned radially outward from the sample distribution annulus element.

16. The aerosol collection device of claim 14 further comprising:
a tube component secured to the sample distribution annulus element; and
a valve component supported by the valve support annulus element.

17. The aerosol collection device of claim 15 , wherein the filter component is inserted between the sample distribution annulus element and the at least one capsule extraction body element, wherein the aerosol collection device further comprises a lower plunger component positioned on a top surface of the filter component.

18. The aerosol collection device of claim 17 , wherein the lower plunger component comprises a plurality of plunger support wings, wherein each of the plurality of plunger support wings is positioned between two capsule components.

19. The aerosol collection device of claim 18 , wherein the upper plunger component is configured to translate from a first configuration to a second configuration by a rotational force, wherein:
in the first configuration, a bottom surface of the upper plunger component is in contact with a top surface of each of the at least one capsule component; and
in the second configuration, the bottom surface of the upper plunger component is in contact with a top surface of each of the plurality of plunger support wings.
