1. An aspiration device comprising:
a cylinder defined by a hollow interior and opposed first and second ends; a one-way check valve positioned between the cylinder first end and a facemask neck;
an activation spring positioned within the cylinder interior at the first end, wherein the activation spring is convertible between a first, compressed position and a second, extended position;
a piston positioned within the cylinder interior, the piston comprising a face that directly contacts the activation spring, wherein the piston is configured to travel between the first and second ends of the cylinder; and wherein the piston divides the cylinder interior into a first chamber that includes the activation spring and a second chamber that includes a piston rod;
an endcap positioned at the second end of the cylinder, the endcap defined by a central aperture and an aspiration button;
wherein the aspiration button comprises a front face, an opposed rear wall, and a central slot with a first region having a first diameter and a second region having a diameter less than the first diameter and positioned adjacent to the rear wall;
wherein the piston rod is attached to the piston at a first rod end, with a length that extends through the endcap aperture, and a second rod end fitted with a knob, wherein the piston rod includes a detent groove adjacent to the second rod end;
wherein the aspiration button is configured to be located in a first locked position wherein the piston cannot advance towards the cylinder second end, and a second aspiration position wherein the piston advances towards the cylinder second end, thereby creating a vacuum in the first chamber.
