Contamination prevention system for bathtub

Claim 1

A contamination prevention system to be installed in conjunction with a bathtub in a bathroom of a health-care institution to prevent the various patients that use the bathtub from cross-infecting each other, where the two ends and the back of the bathtub are built into the bathroom walls, comprising: a series of hooks affixed to the three bathroom walls, surrounding the bathtub, at predetermined spaced-apart locations; a disposable, flexible, flimsy, water-tight, non-toxic, slip-resistant, biologically-clean, rectangular-shaped liner, made of transparent plastic film, for lining the entire inside of the bathtub, before it is filled with water, to provide a barrier to block the transmission of bacteria between the water and bathtub to preclude cross-infections between patients, the peripheral edge portions of said liner adjacent to the bathroom walls having a series of openings at predetermined spaced-apart areas to facilitate hanging of said liner from said hooks, said openings being made by using said hooks to pierce said liner, and the peripheral edge portion adjacent to the front of the bathtub being draped thereover; and a series of spaced-apart markers on said liner, each of which corresponds to a respective assigned one of said hooks, to designate the predetermined areas where said liner should be pierced, to make said openings, and hung onto said hooks, thereby aiding the installer in expediting the proper positioning and centering of said liner within the bathtub.
