Fluid impermeable cover for operating room tourniquet

Claim 2

A tourniquet cover for use in a hospital comprising: a thin flexible sheet of liquid impervious material having a length dimension and a width dimension, the length dimension sufficient to be wrapped around a limb of a patient more than a full revolution to provide overlap of the ends thereof; a padded layer disposed adjacent one edge of said sheet along the length dimension thereof and attached thereto for being wrapped around the patient's limb to provide cushioning thereto, said padded layer dimensioned along the width thereof less than one half the width of said sheet; means for fastening one edge of said sheet along the width dimension thereof to a portion of said sheet in order to maintain said sheet about the patient's limb with said padded layer adjacent the patient's limb such that a tourniquet can be placed over the portion of said sheet adjacent said padded layer, the tourniquet being protected from the skin of the patient by said sheet and said padded layer preventing the skin of the wearer from being pinched by the tourniquet; and said padded layer having a width dimension wider than the tourniquet such that the portion of said flexible sheet not adjacent to said padded layer may be folded over the outer surface of the tourniquet to fully cover and shield the tourniquet from moisture and contamination.

Claim 3

The tourniquet cover of claim 1 wherein said padded portion is ultrasonically bonded to said sheet.

Claim 4

The tourniquet cover of claim 1 wherein said sheet is rectangular and is formed from thin flexible elastomeric material.

Claim 5

The tourniquet cover of claim 3 wherein said padded portion is bonded to said sheet to allow stretching of said sheet without damage to said bond between said padded portion and said sheet.

Claim 6

The tourniquet cover of claim 3 wherein said padded portion covers less than one-half the surface area of said sheet.

Claim 7

The tourniquet cover of claim 1 wherein said fastening means comprises tape attached at one end to one edge of said sheet and having an adhesive end for attaching to a portion of said sheet.

Claim 8

A cover for an operating room tourniquet comprising: a thin flexible sheet of liquid impervious elastomeric material having a length dimension and a width dimension, the length dimension sufficient to be wrapped around a limb of a patient more than a full revolution to provide overlap of the ends thereof and having a width greater than the width of an operating room tourniquet; a pad attached along the length dimension on one side of said flexible sheet for being wrapped around the limb of the patient between the limb and said sheet to provide cushioning for the limb, said pad having a length substantially equal to the length of said flexible sheet and a width at least as wide as an operating room tourniquet but less than one half the width of said sheet; said flexible sheet and said pad stretching when wrapped around the limb of the patient; means for fastening one end of said flexible sheet to another portion of said flexible sheet to maintain the position of said flexible sheet around the limb of the patient; and the portion of said flexible sheet not covered by said pad operable to be folded over the operating room tourniquet affixed over the portion of said sheet adjacent said pad in order to cover and shield the inner and outer surfaces of the operating room tourniquet from moisture and contamination, while preventing the skin of the patient from being pinched by the tourniquet.

Claim 9

A cover for an operating room tourniquet comprising: a thin flexible sheet of liquid impervious elastomeric material having a length dimension and a width dimension, the length dimension sufficient to be wrapped around a limb of a patient more than a full revolution to provide overlap of the ends thereof and having a width greater than the width of an operating room tourniquet; a pad attached along the length dimension on one side of said flexible sheet for being wrapped around the limb of the patient between the limb and said sheet to provide cushioning for the limb, said pad having a length substantially equal to the length of said flexible sheet and a width at least as wide as an operating room tourniquet but less than one half the width of said sheet; said flexible sheet and said pad stretching when wrapped around the limb of the patient; means for fastening one end of said flexible sheet to another portion of said flexible sheet to maintain the position of said flexible sheet around the limb of the patient; and the portion of said flexible sheet not covered by said pad operable to be folded over the operating room tourniquet affixed over the portion of said sheet adjacent said pad in order to cover and shield the inner and outer surfaces of the operating room tourniquet from moisture and contamination, while preventing the skin of the patient from being pinched by the tourniquet.

Claim 10

The cover for an operating room tourniquet of claim 7 wherein said pad is attached to said sheet by stitches which are angled with respect to the side edges of said pad and said sheet in order to allow stretching of said pad and said sheet.

Claim 11

The cover for an operating room tourniquet of claim 8 wherein said stitches are formed by ultrasonic bonding.

Claim 14

The method of claim 10 wherein the sheet is flexible and further comprising: stretching the sheet around the limb of the patient to ensure a tight fit of the shield and the tourniquet.

Claim 15

The method of claim 10 and further comprising: placing a flexible pad attached to the sheet between the limb of the patient and the sheet.
