Low-cost disposable tourniquet cuff
First Claim
1. A low-cost disposable tourniquet cuff, comprising:
- a first sheet formed of flexible material that is impermeable to gas;
a second sheet facing the first sheet and formed of flexible material impermeable to gas;
a bladder seal joining the first sheet to the second sheet around a perimeter to form an inflatable bladder within the perimeter, wherein the bladder has a bladder width dimension and a bladder length dimension greater than the circumference of a patient'"'"'s limb at a desired location;
port means communicating with the bladder and releasably connectable to a tourniquet instrument for establishing a pneumatic passageway for pressurized gas between the bladder and the tourniquet instrument;
stiffener means contained within the inflatable bladder and formed of gas-impermeable material less flexible than the first sheet, wherein the stiffener means has a stiffener width dimension less than the bladder width dimension and is joined to the first sheet to form a non-inflatable portion of the first sheet; and
securing means attached to the non-inflatable portion of the first sheet and adapted to allow a surgical user to releasably secure the cuff around the limb at the desired location so that the bladder overlaps upon itself.

9. A low-cost disposable tourniquet cuff, comprising:
-
a first sheet formed of a gas-impermeable material having a predetermined flexibility;
a second sheet formed of a flexible material impermeable to gas;
stiffener means formed of gas-impermeable material having a predetermined stiffener flexibility less than the predetermined flexibility of the first sheet, wherein the stiffener means is located between the first sheet and the second sheet and wherein the stiffener means is joined to the first sheet within a portion of the first sheet;
a bladder seal joining the second sheet to the first sheet around a perimeter enclosing the stiffener means to form an inflatable bladder within the perimeter, wherein the inflatable bladder has a length dimension greater than the circumference of a patient'"'"'s limb at a desired location;
port means communicating with the inflatable bladder and releasably connectable to a tourniquet instrument for establishing a pneumatic passageway for pressurized gas between the bladder and the tourniquet instrument; and
securing means for securing the cuff around the limb at the desired location so that the bladder overlaps upon itself. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A low-cost disposable tourniquet cuff, comprising:
-
an inflatable bladder having a first bladder side and a second bladder side and a bladder length dimension between first and second bladder ends that is greater than the circumference of a patient'"'"'s limb at a desired location, wherein the first and second bladder sides extend past the first and second bladder ends;
stiffener means contained within the inflatable bladder and formed of material less flexible than the first and second bladder sides;
port means communicating with the inflatable bladder and releasably connectable to a tourniquet instrument for establishing a pneumatic passageway for pressurized gas between the inflatable bladder and the tourniquet instrument; and
securing means including a securing strip of velcro-type material non-releasably attached to the first bladder side and further including a securing strap of mating velcro-type material extending past the first bladder end and non-releasably attached to the first bladder side at an attachment location past the first bladder end, wherein the securing strap is releasably attachable by a surgical user to the securing strip to secure the cuff around the limb. - View Dependent Claims (17, 18, 19)
