Tourniquet cuff system
First Claim
1. A sterile occlusive cuff for facilitating surgery by occluding flow in blood vessels in a patient'"'"'s limb, comprising:
- a sheath having a inflatable portion longer than the circumference of a limb at a desired location on the limb, a width, and a length that is greater than the length of the inflatable portion, the sheath also including a sterile inner side, a sterile outer side, sterile side edges and sterile end edges;
sheath securing means having a sterile first securing element attached to the outer side of the sheath and a sterile second securing element attached to the outer side and extending past an end edge to engage the first securing element when the sheath is applied around a patient'"'"'s limb, thereby overlapping and securing the inflatable portion of the sheath around the limb;
a port having a first end non-releasably attached to the inflatable portion of the sheath at a location on the sheath, a second end, and a port length between the first end and the second end, wherein the port is comprised of sterile material and includes an annular groove in the outside surface of the port near the second end and a ring of sterile and deformable material extending around the outside surface of the port near the second end, and wherein the port length is such that the second end of the port is extendable past a side edge of the sheath, the port thereby establishing a gas passageway from the second end of the port across the side edge of the sheath and to the inflatable portion of the sheath.

Abstract
A tourniquet cuff provides a convenient and safe mechanism for connecting a sterile cuff that is disposed within a sterile surgical field with a source of pressurized air outside of the sterile field. Also provided is mechanism for connecting the cuff'"'"'s inflatable bladder to the end of a tube to establish a gas-tight passageway between the tube and the bladder while allowing rotation of the tube end relative to the bladder in clockwise and counterclockwise directions around the cylindrical axis of the tube and maintaining the gas-tight passageway during and after such rotation and while also ensuring that an operator can disconnect the tube from the bladder only by manually applying an unlocking force and by applying a disconnecting force in a direction at a right angle to the unlocking force while the unlocking force remains applied.

-
a sheath having a inflatable portion longer than the circumference of a limb at a desired location on the limb, a width, and a length that is greater than the length of the inflatable portion, the sheath also including a sterile inner side, a sterile outer side, sterile side edges and sterile end edges; sheath securing means having a sterile first securing element attached to the outer side of the sheath and a sterile second securing element attached to the outer side and extending past an end edge to engage the first securing element when the sheath is applied around a patient'"'"'s limb, thereby overlapping and securing the inflatable portion of the sheath around the limb; a port having a first end non-releasably attached to the inflatable portion of the sheath at a location on the sheath, a second end, and a port length between the first end and the second end, wherein the port is comprised of sterile material and includes an annular groove in the outside surface of the port near the second end and a ring of sterile and deformable material extending around the outside surface of the port near the second end, and wherein the port length is such that the second end of the port is extendable past a side edge of the sheath, the port thereby establishing a gas passageway from the second end of the port across the side edge of the sheath and to the inflatable portion of the sheath. - View Dependent Claims (2, 3, 4)

5. An improved occlusive cuff for facilitating surgery by occluding flow in blood vessels in a patient'"'"'s limb, comprising:
-
a sheath having an inflatable portion longer than the circumference of a limb at a desired location, a width, a length greater than the length of the inflatable portion, an inner side facing the limb, an outer side facing away from the limb, side edges, end edges, and a port having a first port end, a second port end, a port length and formed of flexible thermoplastic material along a portion of the port length, wherein the first port end is non-releasably attached to the inflatable portion of the sheath at a location and in an orientation such that the second port end may be positioned to reside past a side edge of the sheath, thereby establishing a gas passageway between the inflatable portion of the sheath and the second port end, which passageway extends across the side edge; sheath securing means having a first securing element attached to the outer side of the sheath and a second securing element attached to the outer side and extending past an end edge to engage the first securing element when the sheath is applied around the limb at the desired location, thereby overlapping and securing the inflatable portion of the sheath in a substantially circumferential direction around the limb; and a tube having an end and a longitudinal axis at the end and connectable at the second end to the port to establish the substantially gas-tight passageway between the inflatable portion of the sheath and the tube through the port; wherein the tube end includes manually operable tube release means whereby the tube is disconnectable from the port by the application of an unlocking force to the tube release means in a direction substantially at a right angle to the longitudinal axis of the tube end and by the application of a disconnecting force to the tube end in a direction along the longitudinal axis of the tube end and away from the port while the unlocking force remains applied. - View Dependent Claims (6, 7, 8, 9, 10)

11. An improved occlusive cuff for facilitating surgery by occluding flow in blood vessels in a patient'"'"'s limb, comprising:
-
a sheath having an inflatable portion longer than the circumference of a limb at a desired location, a width dimension, a length dimension greater than the length of the inflatable portion, an inner side facing the limb, an outer side facing away from the limb, side edges and end edges; sheath securing means having a first securing element attached to the outer side of the sheath and a second securing element attached to the outer side and extending past an end edge to engage the first securing element when the sheath is applied around the limb at the desired location, thereby overlapping and securing the inflatable portion of the sheath in a substantially circumferential direction around the limb; and a port having a first end, a second end, a predetermined length between the first and second ends, an outer surface of a substantially cylindrical shape near the second end, an annular groove in the outer surface at a first predetermined distance from the second end, and a ring of deformable material extending around the outer surface at a second predetermined distance from the second end, wherein the first end of the port is non-releasably attached to the inflatable portion of the sheath at a location and in an orientation such that the port may be extended across a side edge of the sheath, thereby establishing a gas passageway between the inflatable portion of the sheath and the second end of the port such that the passageway extends past the side edge of the sheath. - View Dependent Claims (12, 13, 14, 15)
