Abstract
Cross-contamination of the patients using the same bathtub in a health-care institution is precluded by lining the tub, before it is filled with water, with a disposable sheet of biologically-clean, flexible plastic film, thereby establishing a physical barrier to prevent any contact (and consequently a transmission path for bacteria) between the bathtub and patient and between the tub and water. Openings are made along the liner's edges in order to hang the liner onto a series of hooks affixed to the three walls surrounding the tub, the hooks being appropriately shaped so that they can be used by the installer to pierce or puncture the liner to make the openings. The liner is merely draped over the front of the tub. Installation is expedited and made easier by providing a series of markers, such as printed rings, along the edges of the liner to designate the areas that should be pierced to achieve proper positioning and centering of the liner within the bathtub.
