Airway assist device

1. An apparatus, comprising:

a barrel having an open barrel proximal end and a barrel distal end having a first opening and a second opening;

a plunger having a plunger proximal end and a plunger distal end, said plunger slidably disposed within said barrel;

a first one-way valve included in said first opening at said barrel distal end through which fluid passes into said barrel upon outward draw of said plunger in said barrel;

a second one-way valve coupled to said second opening through which fluid passes out of said barrel upon inward push of said plunger in said barrel;

a face mask coupled to said first opening; and

a receptacle coupled to said second opening, wherein said receptacle comprises a rigid receptacle or a flexible receptacle disposed between a pair of rigid receptacle end caps disposed a fixed distance apart by a cross member.

2. The apparatus of claim 1 , wherein said face mask has a dome extending to a dome outer periphery configured to engage a subject, wherein said dome comprises a clear material allowing a user to observe said subject engaged to said face mask or a material drawn up from a throat of said subject.

3. The apparatus of claim 2 , further comprising an annular cuff engaged to said dome outer periphery.

4. The apparatus of claim 3 , wherein said annular cuff comprises an inflatable tubular member.

5. The apparatus of claim 1 , wherein said face mask comprises a plurality of face masks which interchangeably couple to said first opening.

6. The apparatus of claim 5 , wherein said plurality of face masks include a range of different sizes.

7. The apparatus of claim 1 , further comprising

a throat tube passing through said face mask, said throat tube having a tube first end fluidically connected to said first opening on said barrel distal end and a tube second end.

8. The apparatus of claim 7 , further comprising one or more notches on a terminal edge of said throat tube second end.

9. The apparatus of claim 1 , further comprising a handle coupled to said plunger proximal end.

10. An apparatus, comprising:

a barrel having an open barrel proximal end and a barrel distal end having a first opening and a second opening;

a plunger having a plunger proximal end and a plunger distal end, said plunger slidably disposed within said barrel;

a first one-way valve coupled to said first opening at said barrel distal end through which fluid passes into said barrel upon outward draw of said plunger in said barrel;

a second one-way valve coupled to said second opening through which fluid passes out of said barrel upon inward push of said plunger in said barrel;

a face mask coupled to said first opening;

a receptacle coupled to said second opening;

a fluid outlet port defining an aperture disposed in said receptacle; and

a filter coupled to said aperture disposed in said receptacle.

11. The apparatus of claim 10 , wherein said filter allows passage of air and precludes passage of liquids or solids.

12. The apparatus of claim 11 , further comprising a perforated filter retainer coupled to said aperture in said receptacle, said filter disposed in said perforated filter retainer.

13. The apparatus of claim 12 , further comprising a perforated filter retainer closure removably or fixedly coupled to said perforated filter retainer.

14. An apparatus, comprising:

a barrel having an open barrel proximal end and a barrel distal end having a first opening;

a plunger having a plunger proximal end and a plunger distal end, said plunger slidably disposed within said barrel;

a face mask coupled to said first opening;

a plunger retainer ring having a radially inwardly directed annular lip defining a plunger retainer ring opening, said plunger retainer ring removably coupled to said barrel proximal end with said plunger extending through said plunger retainer ring opening;

a first concentric ring and a second concentric ring encircling said plunger in spaced apart relation proximate said plunger distal end, said first or second concentric ring engageable with said annular lip of said plunger retainer ring to prevent withdrawal of said plunger from said barrel; and

a first seal encircling said plunger proximate said plunger distal end, said first seal disposed between said first and second concentric rings.

15. The apparatus of claim 14 , further comprising

a third concentric ring encircling said plunger in adjacent spaced apart relation to said first and second concentric rings; and

a second seal encircling said plunger disposed between said second concentric ring and said third concentric ring.
