Description

The invention relates to medical equipment, in particular to surgery, traumatology, devices for temporarily stopping bleeding from an injured limb. According to the Ministry of the Russian Federation for Civil Defense, Emergencies and Disaster Relief (EMERCOM of Russia), the application of a hemostatic tourniquet can be used to temporarily stop severe bleeding for a long time. To reduce the negative impact of the tourniquet on the limbs, it should be applied in accordance with the following rules: before applying, the tourniquet should be placed behind the limb and stretched, bleeding is stopped by the first (stretched) round of the tourniquet, all subsequent (fixing) tours are superimposed so that each subsequent tour is approximately half covered the previous one. The tourniquet should not be covered with a bandage or clothing, i.e. should be visible. The exact time of applying the tourniquet should be indicated in the note, the note should be placed under the tourniquet. The maximum time the tourniquet is on the limb should not exceed 60 minutes in the warm season and 30 minutes in the cold. After applying the tourniquet, the limb should be immobilized (immobilized) and thermally insulated (wrapped) using available methods.

BACKGROUND OF THE INVENTION

Known patents for inventions

RU 2642271 C2 HEAT-STOP PLACE Date of registration: 24.01.2018. The technical result is achieved by a hemostatic tourniquet containing an elastic band of the tourniquet and a locking device for the initial and end sections of the elastic band of the tourniquet at the place of application of the tourniquet, in which the locking device is made in the form of a plate with at least two transverse slots sequentially located along its longitudinal sides, which are open with one of its longitudinal sides, the width of the slot is less than the thickness of the harness tape, and the length of the slot is equal to the width of the harness tape, while the slot on one side of the plate serves to accommodate the initial section of the elastic tape of the bundle, and the slot on the other side of the plate serves to accommodate the end section of the elastic band of the tourniquet.

The disadvantage of this solution is the impossibility of independently assisting oneself in case of damage to the upper limb, and it is also difficult to fix this device in one position with a constant tension force, which will entail a decrease in the effectiveness of assistance. Applying a tourniquet in one round leads to greater trauma to the skin, due to excessive pressure on a small surface area of the skin. (RU 2642271 C2, https://new.fips.ru/)

RU 2531449 C1 HEAT-STOP HARNESS. A hemostatic tourniquet containing the actual tourniquet, made of a flat tape, and a retainer of the applied tourniquet, characterized in that to tighten the flat tape and stop bleeding in the cavity of the flat inelastic tape, two slings are parallel to each other with a gap, one end of the flat tape is fixed on a 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 retainer of the applied tourniquet is installed in the center of the flat tape and contains a base on which it is fixed tourniquet application time indicator and a coil is placed, in the central hole of which a lever is mounted, radial axes with central slotted slots and disk-shaped side guides are made on the side surface of the retainer coil on both sides of the lever, radially oriented slotted slots are made on both edges of the base in front of the coil and behind it. slots, while the lines of the flat tape are sequentially threaded respectively in the slot in front of the coil, in the slot of the radial axis of the coil and in the slot after the coil, and the ends of the lines are fixed in the cavity of the flat tape. The disadvantage of this solution is the complexity of the design, which entails the need for a preliminary thorough analysis of the design of the device before the first use and an increase in the chances of breakage of some of the parts of the structure. All this affects the quality and speed of first aid. Applying a tourniquet in one round leads to greater trauma to the skin, due to excessive pressure on a small surface area of the skin.

ESSENCE DISCLAIMER

The object of the present invention is to provide a method for applying a hemostatic device having a buckle which is atraumatic and easy to use. Within the framework of this decision, a hemostatic device with a buckle should be understood as a device that includes a tourniquet and a buckle in the form of a frame (frame type), including with a crossbar and / or with at least one ledge. The protrusion(s) on the buckle may be located on the frame and/or on the crossbar. They can have the shape of a cone, pyramid, cylinder, and are made at an angle.

The tourniquet can be a flat, including an elastic tape. The harness is fixed on the side of the buckle or on the crossbar. The other end of the harness is free.

The use in a particular case of an elastic band as a tourniquet allows you to pull the affected limb relatively painlessly, without causing additional injuries. The method for applying a hemostatic tourniquet includes a preparation stage, in which the free end of the tourniquet is threaded through the inside of the frame space of the buckle, the wounded limb is threaded into the loop formed, the free end of the tourniquet is wrapped around the limb in the opposite direction (first round (1 TUR - (fr. tour). 1) circle, circular motion. Dictionary of foreign words included in the Russian language. - Chudinov A.N., 1910.)) tourniquet application time.

The shift to the left and right of each subsequent round increases the area of application, which reduces additional injury to the soft tissues of the limb. In the framework of this solution, the reverse movement of the tourniquet after the buckle should be understood. The counterwind allows you to more effectively tighten the tourniquet, since the tension goes through the frame and the loop begins to tighten the limb. In addition, the coil of the first round lies on top of the loop, which reduces the likelihood of injury to soft tissues.

In a particular case of making a buckle with one protrusion, during the preparation stage, the free end of the tow is threaded through the intraframe space of the buckle, leading the end of the tow on the opposite side of the side with the spike, and the second round is pierced onto the protrusion of the buckle, which makes it possible to fix both the tension of the tow and shifted coil position. In a particular case of making a buckle with more than one protrusion, during the preparation stage, the free end of the tow is threaded through the intraframe space of the buckle from the opposite side, the second round is pierced onto one protrusion of the buckle, which makes it possible to fix both the tension of the tow and the displaced position, and subsequent(e) round(s) to another ledge(s) of the buckle, alternating, which allows you to fix the shifted position of each round.

In a particular case of execution with an elastic tourniquet, when applying the first round, i.e. when wrapping in the opposite direction, the free end of the elastic cord is stretched.

In a particular case of a frame with a crossbar, when the harness is fixed on the frame, during the preparation stage, the free end of the harness is threaded through the space of the buckle between the frame and the crossbar on the opposite side from the fixed end of the harness.

In the particular case of the execution of the frame with a crossbar, when the tourniquet is fixed on the crossbar, during the preparation stage, the free end of the tourniquet is threaded through any space of the buckle between the frame and the crossbar.

If necessary, the tension force of the tourniquet in the case of a buckle with protrusions is corrected by releasing the free end of the tourniquet from the protrusions of the buckle, then the tourniquet is pulled around the affected limb with the required force and the free end of the tourniquet is fixed again on the protrusions of the buckle.

In the case of buckles with protrusions, a note is fixed indicating the time the tourniquet was applied, pricking it on the protrusion (s).

This method allows you to stop bleeding, without additional injury to the soft tissues of the limb.

IMPLEMENTATION OF THE DECLARED SOLUTION

The hemostatic device is applied in two stages as follows: at the first stage, preparation is carried out, namely, the free end of the tourniquet is threaded through the hole in the buckle, go to the second stage, the wounded limb is threaded into the loop formed to a position above the wound, the free end of the tourniquet, threaded into the buckle, tighten in the opposite direction, tighten with the next round until the bleeding stops and the absence of peripheral pulsation. Each subsequent round is applied to the limb with a slight displacement to the left and right to increase the area of application, or without displacement, fixed by threading the tourniquet under the tour.

In the particular case of making the tourniquet elastic, when tightened in the opposite direction, the tourniquet is stretched and the affected limb is pulled.

In a particular case of a buckle with a protrusion, the free end of the tow is fixed by pinning it onto a protrusion located on the buckle.

In the particular case of a buckle with two protrusions, the second round is fixed by pinning on one protrusion located on the buckle, the next round is fixed to the second protrusion, etc., alternating.

If necessary, the tensile strength of the tourniquet can be adjusted by detaching the tourniquet from the protrusion(s) of the buckle, adjusting the tension, and re-pinning the free end of the tourniquet onto the protrusion of the buckle.
