Abstract
Abstract A culturing device for gonorrhea including a CO2 cylinder having a swab mounted thereon and closed by a rubberlike diaphragm. The swab is projectable from a cylindrical container for obtaining a specimen. The cylindrical container has a threaded cap thereon and contains a culture medium. The cap has a lance mounted thereon which is usable when the cap is closed on the container to puncture the diaphragm to cause CO2 to fill the cylindrical container. The CO2 cylinder is movable in the cylindrical container to cause the swab to wipe across the culture medium and thereby cause the specimen to be deposited from the swab on the culture medium.
