Abstract

Hemostatic tourniquet is intended for first aid in case of limb injury. It contains a tow of elastic band with a terry effect. The tape is connected to a buckle-frame of a rectangular shape with the formation of a loop with the terry inward. On the free end of the tape, on its smooth side, the velcro hooks are fastened with hooks up to hook on the terry of the elastic braid and fix the attached harness. An overlaid tourniquet consists of at least 2.5 rounds.

Description

The utility model relates to medicine, in particular, to the field of traumatology for first aid.

Rubber tows of Esmarch type, used for a long time to temporarily stop bleeding in injured limbs, are known in various modifications (see. Hemostatic tourniquet. BME, ed. 3rd T. 8). These are the simplest and most common harnesses for medical staff, but they have the following disadvantages: a rubber tourniquet causes pain when squeezing and pinching the skin, and self-help is problematic with such tourniquets, especially since a tourniquet of this class should be relaxed and tightened for about half an hour.

The closest to the claimed result achieved - reliable stopping of arterial bleeding during first aid - is a hemostatic tourniquet containing the tourniquet from an elastic braid with a terry effect on the side of the body and a lock that performs the functions of loop formation, fixation and intermediate weakening of the applied tourniquet .

The well-known tourniquet is easy to handle, easily fastens, loosens and comes unfastened, and the material of the tourniquet with a terry effect on the side facing the body does not cause pain or pinching of the skin when it stops arterial circulation when compressed. The disadvantage of this device is the lack of blocking from unwanted loosening of the harness in the operating position, in which the lock is in a vertical position and is weakened by tilting the entire lock housing forward or backward even when accidentally grabbed. Right castle

should only loosen when you press the rocker arm. In addition, the castle complicates and increases the cost of the final product.

The task, while maintaining the advantages of the prototype, is to simplify and reduce the cost of the device.

The problem is solved in that in a hemostatic tourniquet containing elastic braid with a terry effect on one side, the device for looping the inside with the towel and the fixation device of the superimposed tourniquet, according to the utility model, the loop forming device is made in the form of a buckle-frame of a rectangular shape, and at the free end of the tourniquet, a device for fixing the superimposed tourniquet, consisting of at least 2.5 rounds, is fixed.

In the proposed tourniquet hemostatic device for fixing the superimposed tourniquet is made in the form of braid Velcro hooks.

In the proposed harness, the device for fixing the superimposed tourniquet is fixed on the smooth side of the elastic braid with hooks up.

Figure 1 shows a General view of the device.

The tourniquet of FIG. 1 contains the tourniquet 1 itself, made of elastic braid with a terry effect on one side. One end of the braid is fixedly fixed to the wall of the buckle-frame 2 of a rectangular shape. Through the slit-like opening of the frame 2, the free end of the braid 1 is passed through with the formation of a loop with the terry inward. On the free end of the braid 1, on its smooth side, a velcro-hook tape 3 is fastened with hooks up. Braid 1 can have a terry effect on both sides, but it is more practical and aesthetic to choose a braid with a terry effect on only one side.

The harness works as follows. A wounded limb is inserted into the formed loop of tourniquet 1. Tighten the free end of the harness 1

to stop bleeding and the absence of peripheral pulsation. If the pulse is still audible, tighten the tourniquet 1 a little more, controlling the pulling force by the disappearance of the pulse on the limbs.

Subsequent rounds impose with less tension, but sufficient to prevent the relaxation of the first round and to prevent unbuttoning the last round. Fixation of the tourniquet is carried out by engaging the free end with a tape of velcro hooks 3 for the terry of elastic braid 1, so the next rounds after the first round are imposed with the terry effect on top. The length of the braid 1 during manufacture is selected depending on the purpose of the tourniquet for the thigh and / or forearm, based on at least 2.5 x the average volume of the thigh and / or forearm. The tourniquet relaxes and is removed in the reverse order.

The inventive harness is structurally simple in maintenance and self-service (you can work with one hand). The inventive tourniquet can be used both during venoinjection and in first aid for stopping arterial bleeding. The tourniquet successfully passed medical tests at ambulance stations in the city of Ramenskoye, Lyubertsy, Moscow, has a certificate and registration certificate of the Ministry of Health of the Russian Federation.
