Patent ID: 7775212

Claim:
A self-opening bodily fluid barrier for a patient, comprising: a substantially impermeable sheet of material comprising a substantially rectangular main body panel having a predetermined length and width with first and second opposite ends and first and second opposite side edges, first and second side panels substantially coextensive with the side edges of the main body panel and having a width substantially equal to the width of the main body panel, a foot panel substantially coextensive with the second end of the main body panel and extending away from the main body panel a length generally at least equal to that of its width; a series of elongated inflatable chambers in fluid connection with one another on the sheet of material comprising at least one chamber positioned to extend substantially the entire length of the main body panel, first and second longitudinally spaced apart and laterally extending side chambers on each of the side panels, and a longitudinally extending chamber on the foot panel; an inflation device comprising a container of compressed inflation gas containing enough gas to, when released, more than fill the series of inflatable chambers, a main valve operably interconnecting the container and the series of chambers near the first end of the main body portion and a relief valve operably connected with the series of chambers to vent inflation gas from the chambers when the internal pressure reaches a predetermined point sufficient to fully extend the main body, side and foot panels by turgid inflation of the chambers, wherein, when the bodily fluid barrier has a packed condition in which the first and second side panels are folded onto the main body panel along the side edges, the foot panel is folded onto the main body panel at the second end, and the entire folded sheet is rolled from the second end toward the first end and a deployed condition in which all panels are fully extended and unfolded from the main body panel, the bodily fluid barrier being transitioned from the packed condition to the deployed condition by operation of the main valve to release compressed gas from the container into the series of chambers, the chambers being substantially filled with the gas to extend the chambers to a turgid condition and operation of the relief valve to vent the gas after deployment.
