ABSTRACT:
A suctioning device is provided for use in removal of fluid mucus from the trachea and nostrils of a newborn infant, to prevent aspiration of such fluid into the infant's lungs before first breath; the device includes a vertically, longitudinally, upright container having a bottom wall with an opening therein to pass mucus into the container via a tubular catheter, and a top cap with an opening therein to pass suction air from the container interior toward a suction mouthpiece; a baffle or baffles in the container to intercept upward flow of mucus toward the top cap; a duct in the container to receive flow of mucus via the opening sin the bottom wall, the duct having an outlet end located to eject mucus to fall in a generally downward direction in the container, below the baffle; and a filter or filter above the duct to filter air being sucked from the container interior toward the mouthpiece via the top cap opening.
The filter and one part of the baffle are typically carried by the top cap for endwise insertion downwardly into the container upper extent, the bottom wall is typically defined by a bottom cap received in the container, and the duct and a second part of the baffle are typically carried by the bottom cap for endwise insertion upwardly into lower end extent of the container.
