Surgical drape with improved construction for critical zone panel

A reusable, surgical drape adapted to overlie a patient during the performance of a surgical procedure and having a fenestration for registration with the site of a surgical procedure,

• said drape comprising
• a main panel of a given lateral extent,
• a "critical zone" panel of substantially smaller lateral extent and extending outwardly from said fenestration,
• wherein
• the "critical zone" panel comprises
• a liquid proof, barrier panel, and
• a marginal edge portion of the barrier panel is folded on itself to define a bottom, folded portion, said marginal edge portion being in spaced relation to the main portion of the barrier panel and forms an upwardly open, non-filled trough of substantial depth, extending upwardly from the bottom folded portion, for the reception therein of liquids incident to the performance of a surgical procedure, as well as to trap surgical instruments, or the like which might slip from a position on the "critical zone" panel adjacent the fenestration,
• characterized by
• means for releasably securing said marginal edge portion of the barrier panel to the main portion of the barrier panel, and
• further characterized by
• means for releasably holding portions of the trough forming portions of the "critical zone" panel in further folded relation which closes the ends of the trough.

A reusable, surgical drape adapted to overlie a patient during the performance of a surgical procedure and having a fenestration for registration with the site of a surgical procedure,

• said drape comprising
• a main panel of a given lateral extent, and having side portions adapted to drape beneath the level of an operating table on which a patient is positioned,
• a "critical zone" panel of substantially smaller lateral extent, overlying the main panel and extending outwardly from said fenestration,
• wherein
• the "critical zone" panel is generally rectangular and has side portions generally parallel with the side portions of the main panel and
• said "critical zone" panel extends outwardly on opposite sides of the fenestration to a point where the "critical zone" panel and the main panel are both angled downwardly from a horizontal plane, when the surgical drape is draped over a patient, and
• further wherein
• the "critical zone" panel comprises
• a barrier panel, and
• characterized in that
• the marginal edge portions of the barrier panel, on opposite sides thereof, outwardly of the fenestration, are folded on themselves to define troughs having bottom, folded portions,
• the marginal side edges being in spaced relation to the main portion of the barrier panel and forming upwardly open, non-filled troughs of substantial depth, extending upwardly from the bottom folded portions, for the reception therein of liquids incident to the performance of a surgical procedure, as well as to trap surgical instruments, or the like which might slip from a position on the "critical zone" panel adjacent the fenestration, and
• further characterized by
• means, capable of being repeatedly attached and detached, for releasably securing said marginal edge portions of the barrier panel to the main portion of the barrier panel,
• whereby the surgical drape may be washed and sterilized with the barrier panel in an unfolded condition.
