Abstract
A pneumatic tourniquet adapted for self application by an injured person in a military or emergency situation to stop arterial blood loss in an injured arm or leg comprises: a bladder having a width dimension and having a length dimension greater than the circumference of an injured limb of a subject at a selected location; and clamp means for securing the bladder around the limb at the selected location and adapted for sealing the bladder across the bladder width to establish an inflatable portion of the bladder to be the portion of the bladder that encircles the injured limb at the selected location.
Claims11
A pneumatic tourniquet adapted for self application by an injured person in a military or emergency situation to stop arterial blood loss in an injured arm or leg, comprising:
- a bladder having a width dimension and having a length dimension greater than the circumference of an injured limb of a subject at a selected location;
- and
- clamp means for securing the bladder around the limb at the selected location and adapted for sealing the bladder across the bladder width to establish an inflatable portion of the bladder to be the portion of the bladder that encircles the injured limb at the selected location.
A pneumatic tourniquet adapted for self application by an injured person in a military or emergency situation to stop arterial blood loss in an injured arm or leg, comprising
- an inflatable bladder having a width dimension and having a length dimension greater than the circumference of an injured limb of a subject at a selected location;
- clamp means for securing the bladder around the limb at the selected location so that the bladder remains secured around the limb while the bladder is inflated;
- manual inflation means adapted to allow the bladder to be manually inflated to a pressure sufficient to stop arterial blood loss past the bladder;
- and
- timer means for indicating the duration of time the bladder has been pressurized above a predetermined pressure threshold wherein the timer is activated by the manual inflation of the bladder to a pressure greater than the predetermined pressure threshold.
A pneumatic tourniquet adapted for self application by an injured person in a military or emergency situation to stop arterial blood loss in an injured arm or leg, comprising:
- an inflatable bladder having a first end, a second end and an overall length greater than a circumference of a limb of a subject at a predetermined location;
- clamp means attached to the first end of the bladder and having an open position, an intermediate position and a locked position, wherein the open position is adapted to allow the subject to encircle the limb with the a portion of the bladder at the selected location and insert the second end of the bladder into the clamp means, wherein the intermediate position is adapted to allow the subject to reduce the circumference of the encircling portion of the bladder to be substantially equivalent to the circumference of the limb at the selected location, and wherein the locked position is adapted to allow the subject to secure the encircling portion of the bladder around the limb while the bladder is inflated.
