Abstract: There is provided a guard for an intravenous adaptor. The guard comprises a polymer sheet formed of a polymer film, the polymer sheet having left, right and middle portions; tear lines within the polymer sheet, located on either side of the central extent of the middle portion; a pull strip extending lengthwise, generally parallel to the central extent and positioned between the tear lines; and an adhesive applied to a periphery of the polymer sheet and over the ends of the pull strip, the tear lines penetrating through the adhesive. The left and right portions of the polymer sheet are arranged to be folded onto each other to form a folded polymer sheet adhered by the adhesive to define a pocket, which is openable by tearing the folded polymer sheet and adhesive along the tear lines.
