摘要：
Low-cost tourniquet cuff apparatus includes: an inflatable bladder formed of flexible material having a bladder width dimension when the bladder is uninflated and a having a bladder length dimension sufficient for encircling a limb of a surgical patient at a desired location on the limb and for overlapping upon itself, wherein the bladder includes a bladder first inner surface facing a bladder second inner surface along the bladder length dimension and across the bladder width dimension when the bladder is uninflated securing means for securing the overlapping bladder around the limb at the desired location port means communicating pneumatically with the inflatable bladder and releasably connectable to a tourniquet instrument for supplying the bladder with pressurized gas and stiffener means having a predetermined stiffness and having a stiffener width dimension less than the bladder width dimension, wherein the stiffener means is non-releasably attached to the bladder first inner surface within the inflatable bladder. The stiffener means may have a stiffener length dimension that is at least equal to the limb circumference. A method of making the low-cost tourniquet cuff allows the cuff elements to be simply assembled and then sealed in one operation using radio-frequency welding or a similar process.
