Claim:
A pneumostoma vent to allow gases to exit parenchymal tissue of a lung through a pneumostoma in a chest of a patient, wherein the pneumostoma vent comprises; a tube adapted to be inserted into the chest through the pneumostoma, the tube having a lumen, a proximal end and a distal end the distal end of the tube having at least one opening adapted to admit gases from the parenchymal tissue of the lung; the proximal end of the tube having a plurality of arms projecting a sufficient distance from the tube to preclude passage of proximal end of the tube through a wall of the chest into the pneumostoma, an adhesive ring surrounding the tube; the adhesive ring having an aperture through which the tube passes, the aperture being too small to allow passage of the arms projecting from the tube; a filter disposed over the proximal end of the tube such that gases passing into and out of the lumen of the tube pass through the filter; an adhesive cover having an aperture smaller than the filter and positioned such that the adhesive cover contacts the perimeter of the filter, the arms of the tube and at least a portion of the adhesive ring, such that the arms are disposed between the adhesive ring and the adhesive cover, and the filter is disposed between the adhesive cover and the proximal end of the tube.
