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.

Claims

1. A noninvasive seal for a sucking chest wound, which comprises:

a. A rectangular flexible base means having an aperture in the center and having its bottom surface covered with a layer of an adhesive material adapted to be adhered to a patient'"'"'s body in surrounding relationship to the wound;

b. a self-adhering ring seal means securedly attached at the underside of said base means in surrounding relationship to said central aperture and having its inner diameter equal to that of said aperture to further insure a fixed position of said base means in relation to the wound and to further prevent leaking of fluid from the wound and leaking of air into the wound;

c. a one-way check valve means, made of a Teflon-coated rubber, fixedly disposed on said base means, said valve means having its central bore in the registered relationship with said aperture in said base means, said valve means permitting a continuous expellment of air from a chest cavity of the patient exterially through said aperture in the base means and said central bore in said check valve means and prohibiting the intake of air into the chest cavity, said valve comprising a circular flange means horizontally extending from its lowermost portion through the aperture in said base means to the underside of said base means between the bottom surface of said base means and the upper surface of said seal means, the length of said flange means being substantially equal to the width of said ring seal means, said check valve further comprising a body integrally connected to said flange means, said body having a generally polygonal shape, and which terminates in an upper end conical section which is provided with a slot through the top thereof to permit air which has collected in the chest cavity to escape therefrom;

d. a dome shaped, non-collapsible cap means securedly attached to said base means in covering surrounding relationship to said valve means, said cap means having a plurality of apertures adjacent its top portion to facilitate expoundment of air from said chest cavity after the air has passed through a slot in the uppermost portion of said check valve means, and to serve as a protective shield for said wound.
