Description

FIELD OF TECHNOLOGY TO WHICH A USEFUL MODEL IS

The utility model relates to medicine, in particular, to means for stopping bleeding, for example, during intravenous injection and first aid for temporary stopping bleeding.

BACKGROUND

Various means for stopping bleeding are known in the art. As the simplest and most usual for medical staff, we can mention Esmarch type rubber bands in various modifications (see hemostatic tourniquet. BME, 3rd edition, v. 8). These funds have the following disadvantages: a rubber tourniquet causes pain when squeezing and pinching the skin, requires special care, self-help is very problematic, especially since a tourniquet of this class needs to be relaxed and tightened for half an hour.

From the patent of the Russian Federation No. 103465, a hemostatic tourniquet is known, which contains the tourniquet made of elastic braid, a loop forming device made in the form of a buckle-frame, and an attached tourniquet fixation device made in the form of a hook (s) located on the wall of the buckle- framework. This hemostatic tourniquet is considered as the closest analogue (prototype) of this utility model.

An advantage of the prototype is the ability for the user to apply the tourniquet independently, with one hand. The disadvantages of the harness include the implementation of the locking device based on hooks, which complicate the use of the harness. Namely, the presence of hooks leads to unnecessary compression of the patient's limb when applying the tourniquet (at least the application of the first round) due to the need to insert a tourniquet tape behind the bent end of the hook for fixation. In addition, the need to insert the tape of the tourniquet behind the bent end of the hook complicates the calculation of the place where the tape was tipped onto the hook to obtain the desired compressive strength of the limb after the fixation. As a result, it is difficult for an inexperienced user, especially under stress, to apply a known tourniquet properly, without over-clamping the limb. These circumstances complicate the handling of the tourniquet and may cause discomfort in the area of its imposition.

The present utility model is aimed at expanding the arsenal of means to stop bleeding, which is achieved by creating a hemostatic device, an alternative to the known hemostatic tourniquets described above. The technical result provided by the utility model consists in realizing the purpose of the claimed device, namely, in ensuring that the bleeding is stopped by the device.

DISCLOSURE OF THE ESSENCE OF A USEFUL MODEL

The hemostatic device according to a utility model comprises a tourniquet fixed at one end to a buckle made in the form of a frame, and is characterized in that the buckle comprises a straight projection for fixing the free end of the tourniquet. Thus, the design of the device and the process of fixing the tourniquet when applied to stop bleeding are simplified.

In a preferred embodiment of the utility model, the buckle further comprises a second straight protrusion for fixing the free end of the bundle. This configuration allows you to further simplify the application of the bundle, in particular, fixing the free end of the bundle.

Preferably, each of said protrusions is in the form of a cone-shaped spike or has a tapering and / or pointed end to facilitate piercing the tow band when it is fixed to the protrusion or protrusions. Alternatively, the end may be rounded to prevent an injection of the limb.

In one embodiment of the utility model, the buckle comprises a jumper to increase the rigidity of the buckle. At the same time, at least one of these protrusions can be placed on the jumper.

In a preferred embodiment, the buckle is made of polypropylene by injection molding, which is effective from the point of view of automation and mechanization of the manufacturing process. In this case, the protrusion / protrusions and / or jumper can be made integrally with the buckle, which improves the convenience of manufacturing and the durability of the buckle.

Also, in a preferred embodiment, the tow is made in the form of a strip of elastic material, for example, a fabric-elastic material. Such materials have proven effective in temporarily stopping bleeding in various injuries.

For a more reliable fixation of the free end of the bundle, the protrusion or protrusions on the buckle can be provided with at least one of: a thickening, a recess, a notch, roughness, or other relief element.

BRIEF DESCRIPTION OF THE DRAWINGS

In FIG. 1 shows a general view of a hemostatic device according to a utility model.

In FIG. 2a and 2b show, respectively, a side view and a top view of a buckle of a hemostatic device according to a utility model.

IMPLEMENTATION OF A USEFUL MODEL

In FIG. 1 shows a general view of a hemostatic device according to a utility model, which comprises a tourniquet 1 fixed at one end to a buckle 2. Buckle 2 in FIG. 1 contains two straight protrusions 3 for fixing the free end of the bundle 1.

It should be noted that the term “straight” in relation to the protrusion of the hemostatic device according to the present utility model characterizes the implementation of the protrusion, the longitudinal axis of which extends essentially in a straight line from one end of the protrusion to the other, at a right angle from the plane of the buckle.

The tourniquet 1 is a strong relatively narrow and long strip applied to press the vessel to the bone protrusions, to reduce its clearance, and, as a result, to stop or significantly reduce bleeding. An elastic material, for example rubber, or other suitable material known to those skilled in the art, preferably fabric-elastic, can be used as the material of the tow. The length of the harness 1 is selected depending on the specific purpose, for example, for the thigh and / or forearm.

The buckle 2 is made in the form of a frame, for example, a closed rounded frame as shown in FIG. 1. At the same time, the buckle 2 can be made in the form of an open loop frame, which ensures proper fastening and fixing of the bundle on the buckle. The fastening of the harness to the buckle can be realized by any suitable means known from the prior art, for example, by flashing the fixed end of the harness 1, as shown in FIG. 1. Optionally, the buckle 2 may include a jumper 4 to enhance rigidity and / or to accommodate the protrusion or protrusions 3.

FIG. 1, 2a and 2b show the configuration of a hemostatic device according to a utility model, in which the buckle 2 comprises two protrusions 3 located substantially symmetrically on opposite sides of the buckle 2. This configuration of the buckle 2 further facilitates the application of the device, allowing the tourniquet 1 to be inserted between the protrusions 3 .

It should be borne in mind that other buckle configurations with a protrusion 3 are also possible for fixing the free end of the bundle 1. Examples include (not shown in the drawings) when there is only one protrusion 3 located on one of the sides, or a protrusion the protrusions are located on the jumper 4 (if any). The number of protrusions, if necessary, may be more than two.

The buckle 2 can be made, for example, of polypropylene by injection molding or other known method. The protrusion or protrusions 3 and the jumper 4 can be made integrally with the buckle.

Moreover, the utility model provides for various options for performing the protrusion itself or protrusions 3.

Preferably, as shown in FIG. 1 and FIG. 2a, the protrusion 3 is made in the form of a conical spike, tapering from the base to the top. Alternatively (not shown in the drawings), the protrusion body may have a uniform thickness or diameter (in the case of a circular cross section) in a selected area, starting from the base of the protrusion, and have a tapering end, for example, conical. In this case, the protrusion resembles a sharpened pencil in shape.

As shown in FIG. 1, a tip may be present at the top of the protrusion 3. Alternatively, the end of the protrusion 3 may have a more rounded apex, as shown in FIG. 2a, in order to avoid injuries to the limb from an injection with the end of the protrusion.

Optionally, on the protrusion 3, in various places along its length, one or more elements can be placed in the form of thickenings, recesses, notches, roughness or other similar relief elements that can increase the reliability of fixing the free end of the bundle on the protrusion 3. For example, the thickening can be placed at the end of the protrusion 3.

Hemostatic device according to a utility model operates as follows. The free end of the bundle 1 is threaded through the hole of the buckle 2, in particular into the hole formed by the jumper 4 and one of the sides of the buckle, as shown in FIG. one.

An injured limb is passed through the formed loop of the tourniquet 1, after which the free end of the tourniquet 1 is pulled to stop bleeding and the absence of peripheral pulsation. Then, if the pulse is still audible, the tourniquet 1 is pulled back a little more, controlling the pulling force by the disappearance of the pulse on the limb. Fixation of the tourniquet 1 is carried out by putting on its free end on the protrusion or on the protrusions 3, with piercing the tourniquet 1 by the end of the protrusion 3.

Subsequent tours can be imposed in a similar way, but with less tension. The tension should be sufficient to prevent the relaxation of the first round and prevent the unfastening of the last round. The device harness is loosened and removed in the reverse order.

Hemostatic device is an alternative to the prototype, has a simple design and is easy to use, because can be used by the patient himself, allowing you to work with one hand.
