ARRESTING BLEEDING TOURNIQUET Russian patent published in 2014 - IPC A61B17/12 A61B17/132 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, particularly to devices for temporary haemostasis from an injured extremity. The arresting bleeding tourniquet comprises a tourniquet itself made of a flat band, and an applied tourniquet fixative. Two gapped parallel cords are provided for tightening the flat band and ensuring haemostasis within the flat non-elastic band. One end of the flat band is fixed on a locking clamp in the form of a rectangular frame, while the other end of the flat band is connected to a locking tongue which together with the clamp provides looping for the patient's extremity. The applied tourniquet fixative is arranged in the middle of the flap band and comprises a base, wherein there is a time indicator of the applied tourniquet and a coil with a lever mounted in the central hole. On the side surface of the fixative coil, on both sides of the lever there are radial axes with central slots and disk-like side guides. On both edges of the base, in front of the coil and behind it, there are radially directed slots. The flat band cords successively pass through the slot in front of the coil, in the slot of the radial axis of the coil and in the slot behind the coil respectively. The cord ends are fixed in the flat band cavity.

EFFECT: invention enables providing higher comfort and reducing the time of the tourniquet application on the injured extremity; makes it possible to perform the operation fast and with one hand with minimum physical effort; provides the haemostasis from the upper and lower extremities of the compressed tissues; the presence of the time indicator of the tourniquet application enables controlling the patient's injured extremity state, eliminating a possibility of the long-term (more than 2 hours) nerve compression followed by paralyses, as well as preventing tissue necrosis.
