Abstract: A playyard top rail comprising a left rail and a right rail pivotably coupled to the left rail to enable pivotable movement of the right rail relative to the left rail about a pivot axis, and wherein the right rail is formed to include a locking aperture, and also including a lock coupled to the left rail, and wherein the lock includes a lock button arranged along the left rail displaced a distance from the pivot axis to move between a locked position extended into the locking aperture formed in the right rail to block pivotable movement of the right rail relative to the left rail and an unlocked position withdrawn from the locking aperture formed in the right rail to allow pivotable movement of the right rail relative to the left rail.

Abstract: A method for expanding the volume of interior nasal air passages (65 and 67) by introducing separating forces in anatomical outer nasal wall tissues (62 and 64) to enhance oxygen flow and minimize obstruction caused by the presence of nasally inserted medical tubing, which further supports and retains various combinations of oxygen cannula (68), a nasogastric suction tube (35), or an enteral feeding tube (40). This method includes a device containing a clip assembly (14), adjustable arm (18) and dilator patch assembly (12). The primary purposes of this method are to reduce incidence of secondary infection, increase efficacy of oxygen therapy and improve patient comfort.
