METHOD OF DETERMINING HEMOSTATIC PRESSURE IN HEMOSTATIC DEVICE

Provided is a method of determining a hemostatic pressure in a tourniquet includes: driving a limb occlusion pressure (LOP) sensor, which measures a pulse signal of a subject, at a first brightness (S1); checking whether the LOP sensor and a main body are connected to each other (S2); providing a first hemostatic pressure from the main body to the tourniquet (S3); checking, on the basis of a result value of the LOP sensor, whether a pulse of the subject is detected (S4); and, when, on the basis of the result value of the LOP sensor, the pulse of the subject is determined as "not detected," providing a hemostatic pressure, which is obtained by increasing the current hemostatic pressure by a safe hemostatic pressure, from the main body to the tourniquet (S7).
