Battle application tourniquet for limb
View Patent ↗The present invention relates generally to an emergency tourniquet for rapidly and easily reducing or stopping blood flow to an injured limb. The tourniquet utilizes a closed loop system that is formed by passing a portion of a twistable strap, which comprises the loop, through a side opening in a buckle and cinching the strap tightly above an injury and thereafter twisting the strap. Otherwise, a loop may be formed and the injured limb passed through the loop prior to tightening it about the injured limb. The buckle includes an elongated opening that accepts an end or edge of the twistable strap. A free end of the twistable strap passes into a J-hook opening and is secured therein. The strap is then twisted and a notch in the buckle is hooked on an edge of the twistable strap. Bulbous regions are provided on either end of the buckle. A base plate may also be included for further securing the buckle in place to maintain the tourniquet in place until it can be removed by a competent medical professional.
1. A tourniquet comprising:
a buckle having a first and second notch formed in a first side, said first notch comprising a channel that extends upward from the first side to terminate in an opening, said channel including a sloped edge terminating in a rounded corner that extends to a straight edge that is substantially parallel to the first side, an upward extension forming a generally J-hook at an end of the straight edge opposite said rounded corner, said second notch formed by a straight edge that is perpendicular to the first side and terminating in a rounded corner that extends into a sloped edge, an elongated opening formed substantially near a second side and extending in a lengthwise manner from a top towards a bottom of the buckle, a first bulbous region provided at the top of the buckle, a second bulbous region formed in the bottom of the buckle, said first and second bulbous regions aiding in gripping the buckle when the tourniquet is applied to an injured limb; and,
a strip of webbing having a first end and a second end, said second end comprising a permanent loop attached to the elongated opening in the buckle; wherein said elongated opening of the buckle receives an end of the strip of webbing such that an end of the strap is fed through the elongated opening and folded back across itself and stitched to secure the strap to the buckle,
wherein said strip of webbing is inserted into the channel to be seated between the J-hook and the rounded corner of the channel.
2. The tourniquet of claim 1 further comprising a back plate having at least one loop through which the strip of webbing is fed and a pair of straps fastened to a back side of the back plate, each of said straps including a fastener attached thereto.
3. The tourniquet of claim 2 wherein said a back plate is formed from a rigid material and overlapped with fabric which is stitched thereto.
4. The tourniquet of claim 2 wherein the back plate is formed from webbing material and having loops stitched to a front side of the back plate for receiving a free end of the strip of webbing.
5. The tourniquet of claim 2 wherein each of said pair of straps includes a metal end and a ladder lock attached thereto.
6. The tourniquet of claim 2 wherein said back plate includes openings on either side which forms a loop through which a free end of strap is passed.
7. A tourniquet comprising:
a buckle having a first and second notch formed in a first side, said first notch comprising a channel that extends upward from the first side to terminate in an opening, said channel including a sloped edge terminating in a rounded corner that extends to a straight edge that is substantially parallel to the first side, an upward extension forming a generally J-hook at an end of the straight edge opposite said rounded corner, said second notch formed by a straight edge that is perpendicular to the first side and terminating in a rounded corner that extends into a sloped edge, an elongated opening formed substantially near a second side and extending in a lengthwise manner from a top towards a bottom of the buckle, a first bulbous region provided at the top of the buckle, a second bulbous region formed in the bottom of the buckle, said first and second bulbous regions aiding in gripping the buckle when the tourniquet is applied to an injured limb;
a strip of webbing having a first end and a second end, said second end comprising a permanent loop attached to the elongated opening in the buckle; and,
a back plate having at least one loop through which the strip of webbing is fed and a pair of straps fastened to a back side of the back plate, each of said straps including a fastener attached thereto
wherein said elongated opening of the buckle receives an end of the strip of webbing such that an end of the strap is fed through the elongated opening and folded back across itself and stitched to secure the strap to the buckle, and
wherein said strip of webbing is inserted into the channel to be seated between the J-hook and the rounded corner of the channel.
8. The tourniquet of claim 7 wherein said a back plate is formed from a rigid material and overlapped with fabric which is stitched thereto.
9. The tourniquet of claim 7 wherein the back plate is formed from webbing material and having loops stitched to a front side of the back plate for receiving a free end of the strip of webbing.
10. The tourniquet of claim 7 wherein each of said pair of straps includes a metal end and a ladder lock attached thereto.
11. The tourniquet of claim 7 wherein said back plate includes openings on either side which forms a loop through which a free end of strap is passed.
