ABSTRACT:
A noninvasive seal for a sucking chest wound has a rectangular base portion with an aperture in its center, and which is covered with an adhesive substance on its bottom surface. A one-way check valve has an outwardly extending horizontal flange at its lowermost portion, this flange is mounted on the underside of the base portion around the aperture in such a matter that a central opening in the valve body and the aperture in the base portion register with each other. The body of the check valve is made of a Teflon coated rubber to prevent blood from adhering to its inner walls. A seal ring made of Karaya-type gum having a diameter approximately equal to the length of the flange is mounted under the flange, and by adhering to it assures a fixed position of the check valve about the base and therefore about a wound. A dome shaped cap made of a noncollapsible plastic is mounted in covering relationship to the valve directly to the base portion by means of an adhesive applied to its flanges located on the lowermost portion of the dome and extending horizontally in parallel relationship to the base. A plurality of bayonet air slots are made around the periphery of the top portion of the cap to facilitate expellment of air (which has been trapped in a chest cavity) after it exits through a slot in the check valve. The adhesive bottom surface of the base and the seal ring is covered with the protective cover which is peeled off prior to mounting of the device on a patient's body.
