Tourniquet

Abstract

The present disclosure provides a tourniquet, including a surrounding device , a measuring portion (12), and an elastic band portion (13) connected in series, wherein the measuring portion (12) defines an accomodating space (121) for placing an air bag device (20) with an elastic air bag (21). A radial resonant ring formed by connecting the measuring portion (12) and the elastic band portion (13) in series can reduce the influence of non-radial vibration, so as to improve the sensitivity and accuracy of the radial resonance of the tourniquet of the present disclosure.
