Abstract
Abstract A tourniquet for restricting the venous flow of blood is formed by a strip of elastic material having a series of spaced apertures adapted for selective engagement with an upstanding stud for holding the tourniquet tightened around a body member. The apertures are unevenly spaced to compensate for the stretch of the strip so that substantially the same constricting pressure is applied regardless of the size of the body member.

Claim 1
Independent Claim
187 words
A tourniquet adapted to be placed in encircling relation on a body member for restricting the venous flow of Blood comprising a strip of elastic material, fastening means carried by the strip adjacent to a first end portion thereof, said strip having a plurality of spaced apertures extending lengthwise thereof from a point spaced from the fastening means and thence towards the second end portion of the strip, said apertures being adapted for selective engagement with the fastening means for exerting on a body member a constricting pressure for restricting the venous flow of blood, the optimum constricting pressure being provided when the strip is tightened around a body member with the aperture nearest to the fastening means in engagement therewith, the remaining apertures being unevenly spaced to compensate for the stretch of the strip when it is tightened around body members of larger sizes, the spacings between successive apertures increasing in length progressively by a substantially fixed increment beginning with the spacing nearest to the fastening means whereby substantially the same optimum predetermined constricting pressure will be exerted on a body member regardless of its circumference.
