(RU 177273 U1, A61B17/12, 02/14/2018).

A hemostatic tourniquet is known, containing the tourniquet itself, made of a flat tape, and a retainer of the superimposed tourniquet, characterized in that to tighten the flat tape and stop bleeding in the cavity of the flat inelastic tape, two slings are located parallel to each other with a gap, one end of the flat tape is fixed on the locking buckle, made in the form of a rectangular frame, and the other end of the flat tape is connected to a locking "tongue", which, together with the buckle, provides a loop for applying it to the patient's limb, and the clamp of the applied tourniquet is installed in the center of the flat tape and contains a base on which a tourniquet application time indicator is fixed and a coil is placed, in the central hole of which a lever is mounted; slotted slots, while the slings of the flat tape are sequentially threaded, respectively, in the slotted slot in front of the coil, in the slotted slot of the radial axis of the coil and in the slotted slot after the coil, and the ends of the straps are fixed in the cavity of the flat tape (RU 2531449 C1, A61B 17/12, A61B 17 /132, 20.10.2014).

The closest analogue of the claimed invention is a tourniquet device designed for primary use with pressure on the artery in the patient's limbs and for secondary use in the form of a belt wrapped around the user's torso, while the tourniquet device contains: a belt having a proximal end part and a distal end Part; a first buckle assembly connected to a proximal end of the belt; a second pulley assembly slidably connected to the webbing and movable between a proximal end portion and a distal end portion, the second pulley assembly having first and second openings through it, the second pulley assembly being spaced apart from the first buckle assembly; a second pulley assembly having a pulley assembly support and a first pulley element rotatably coupled to the pulley assembly support and deviating from the pulley assembly support; a first buckle assembly having a frame for connecting to a proximal end portion of the belt and defining an opening in which at least one post passes through the opening; the first buckle assembly further has a second pulley rotatably coupled to the frame, the second pulley pivoting away from the frame; a belt passing through the first and second holes of the second pulley assembly and then around the second pulley of the first buckle assembly; wherein the two-to-one pulley is formed by the first and second pulleys and a belt passing therebetween; and furthermore, an opening is formed through which, on the first such use, such an artery in such a limb may pass and be surrounded, and, on the second such use, such a tourniquet may be worn as a belt. (WO 2019036203 A1, A61B 17/12, A61B 17/132, 02/21/2019).

The disadvantages of the above technical solutions is that when they are used for self-help and mutual help, more actions and more physical effort are required, and as a result, more time is spent to stop blood flow from the wounded limb.

The technical problem to be solved by the claimed invention is the improvement of the design of the hemostatic tourniquet-tourniquet in order to reduce the time of its application to stop the blood flow from the wounded limb with less effort.

The technical result of the claimed invention is the simplification of the procedure for applying a tourniquet to a bleeding limb and the creation of the possibility of carrying out this operation with one hand with less effort, without the use of fine motor skills of the hand and fingers, with the help of which the tourniquet is used.

The technical result of the claimed invention is achieved in that the hemostatic tourniquet of the tourniquet type contains a flat sling, at the ends of which the first and second groups of power pulley blocks are placed, characterized in that the first and second groups of power pulley blocks are connected to each other by a cord laid in series through them, the ends which go out in one direction and are fixed on a holder made in the form of a half-ring, while the cord is made with the possibility of tightening the entire length of the cord by pulling its two ends at the same time, and the bundle contains at one end of the flat sling a protective-fixing flat sling laid through the first and the second group of blocks of power pulley blocks and fixed together with the ends of the cord on the said holder, a contactor located at one end of the flat sling, and a carabiner hook for connection with the contactor located at one end of the flat sling.

In addition, in each group of blocks of power chain hoists, at least two blocks of power chain hoists are made in the form of rollers, and the contactor consists of a frame with a roller at the end, on which at least one row of teeth is located, and a base against which these teeth abut, restraining a flat sling, which are made with the possibility of attaching to each other on a common axis with the possibility of rotation around it, and made with the possibility of interacting with each other.

The list of positions of the elements shown in Fig. 1-5:

- The first group of blocks of power chain hoists (1);

- The second group of blocks of power chain hoists (2);

- Cord (3), laid in series through the blocks of the first and second groups;

- Flat sling (4);

- Protective-fixing flat sling (5);

- Hook carabiner (6);

- Closing device consisting of frame (7) and base (8);

- The holder, made in the form of a half ring (9).

A hemostatic tourniquet (Fig. 1), which includes - at the ends of a flat sling (4) the first group of power pulley blocks (1) and the second group of power pulley blocks (2) are located, with a cord (3) laid in series through them, the ends of which are attached to a holder made in the form of a half ring (9), a protective and fixing flat sling (5), a hook-carabiner (6), to which the contactor is attached, consisting of a frame (7) and a base (8).

At the ends of the flat sling (4) shown in figure 2, there are the first group of blocks of power chain hoists (1) and the second group of blocks of power chain hoists (2), with a cord (3) sequentially laid through them, the ends of which are attached to a holder made in the form of a half ring (9), a protective and fixing flat sling (5).

In FIG. 3-5 shows a contactor consisting of a frame (7) and a base (8).

Hemostatic tourniquet-tourniquet consists of a flat sling (4) with the possibility of closing it into a loop around the injured limb. To achieve a hemostatic effect, it is necessary that the limb at the location of the loop be compressed with sufficient force. To do this, a flat sling (4) at both ends is equipped with one group of blocks of power chain hoists (1, 2) in the form of rollers arranged in a row on the same axis with the possibility of rotation around it, which provide the ends of the loop to be pulled together by pulling the cord (3), laid in series through these groups of blocks of power chain hoists.

The ends of the flat sling (4) are provided with two groups of blocks of power chain hoists (1, 2), which are located in a row relative to each other, and a cord (3) is laid through them, connecting the blocks of both sides in series. The cord (3) is looped so that it can be grabbed at both ends at the same time for its further tension in order to pull the ends of the flat sling (4) to each other.

As a result of the tension of the cord (3), the power chain hoists (1, 2) work, which increase the applied force to the ends of the flat sling (4), pulling them together with more force than the applied force at the ends of the cord (3), on which the initial tension occurs .

One of the ends of the loop of the flat sling (4) is equipped with a carabiner hook (6) and a connector (7, 8) for quick and easy connection or disconnection from each other. The closure consists of a frame (7) with a roller at the end, on which at least one row of teeth is located, and a base against which these teeth abut, holding back a flat sling. The frame (7) and the base (8) are mounted on a common axis with the possibility of rotation around it, interacting with each other.

A hemostatic tourniquet is used as follows.

The tourniquet tourniquet is pre-folded into a combat position for its quick, convenient and silent extraction from the pouch in which it is stored. Depending on the location of the wound in the arm or leg, the end of the flat sling (4), which is equipped with a carabiner hook (6) and a contactor (7, 8), can either be connected or disconnected. After that, the tourniquet is put on the limb above the wound with bleeding, and the resulting loop from the flat sling (4) is tightened as tightly as possible to the limb. Next, the compression mechanism is activated from blocks of power chain hoists (1, 2) connected in series with a cord (3) by applying force to its ends attached to a holder made in the form of a half ring (9). As a result of the operation of the blocks of power chain hoists (1, 2), the ring of the flat sling (4) is compressed, thereby stopping the blood flow.

As a result, to achieve a stoppage of blood flow, you need to perform two basic simple actions - pull the end of the flat sling (4) to initially fix the tourniquet tourniquet, then pull again on the holder made in the form of a half ring (9), to which the ends of the cord are attached (3 ). Unlike other analogues, there is no need to rotate the knob, thereby involving the fine motor skills of the fingers and hand of the hand with which the tourniquet is used. And power pulley blocks make it possible to stop the blood flow with less effort.
