Description

The utility model relates to medical equipment, in particular to devices for temporarily stopping bleeding from an injured limb.

The prior art various designs of hemostatic tourniquet, which with varying degrees of effectiveness are used in wide medical practice.

The simplest and very first of the hemostatic tourniquets is Esmarch’s rubber hemostatic tourniquet, which was proposed by the German surgeon F. Esmarch during the Franco-Prussian War (1870-1871) and consisted of a rubber tube with a metal chain at one end and a hook on the other [1 ]. Limb compression control in such a tourniquet was ensured by selecting the chain link with which the hook was engaged. Since the end of the 70s of the last century, this harness was discontinued and replaced by a Langenbeck rubber band, which is a rubber band with buttons oriented in the longitudinal direction at one end and button holes at the other end [2] . However, this tourniquet, despite its widespread use, has significant drawbacks: the tourniquet tape is easy to tear even with your hands, and its contact with the skin when stretched during the application of the tourniquet often leads to pinching and subsequent skin necrosis; the presence of holes for the buttons lead to frequent tears in their area; the use of buttons as clamps in combination with tear-resistant holes significantly reduces the reliability of fastening and the term of use of the harness. In addition, harnesses of this type are inconvenient to apply due to their large lengths; eye and face injuries may occur if handled improperly. Such tourniquets can only be applied to clothing due to the aforementioned pinching of the skin during application. In the event of a break, the tourniquet is not suitable for use and cannot be repaired. The harness is also not suitable for use at temperatures below 5 ° C.

Over the next 40 years, many modifications of tape rubber bands were created, in particular in the fastener fastening system or to prevent tissue injuries. So, an atraumatic hemostatic tourniquet “ALPHA” was developed [3]. The tourniquet is a tape with a corrugated surface and a cord in the form of a loop at one end of the tourniquet. In the tourniquet of this corrugation design (vertical ridges), the integrity of nerve bundles and trophic skin is maintained at the clamping site. The design also provides: the ability to fix the tourniquet with one hand; maximum fixation of the tourniquet when applying the first round; minimum time for applying the tourniquet (about 10 seconds); simplicity and ease of fixation (a convenient fastener in the form of a rubber loop, when it breaks, it is enough to tie a new knot on it without removing the tourniquet from the damaged limb). In some sources, this tourniquet is referred to as the safest when applied to bare skin.

At the same time, none of the modifications, including the ALFA hemostatic tourniquet, provides a solution to the problem of fulfilling the whole complex of requirements that are imposed on all hemostatic tourniquets. Among a number of these requirements, the main ones should be noted:

1. The tourniquet should completely stop the flow of blood from the damaged artery, provided that it is properly applied.

2. The tourniquet must not injure arteries, nerves and underlying tissue. As a rule, this is noted with excessive clamping of the limbs and is caused by the presence in the construction of the bundle of metal or plastic fasteners.

3. The tourniquet must have a structure that makes it possible to use it in any climatic conditions and in any light.

4. The tourniquet must have a structure that allows it to be applied to bare skin.

5. The tourniquet should have a structure that provides the ability to easily and quickly overlap it and remove it just as quickly.

6. The tourniquet should have a simple design, which provides the possibility of its imposition by any person, regardless of the person's skills in using this tourniquet.

7. The tourniquet should be easily washed from dirt and blood.

When upgrading or creating new designs of harnesses, in particular harnesses such as turnstiles, developers, as a rule, try to take into account all the requirements mentioned above. However, usually, in the known constructions, the simultaneous fulfillment of all these requirements is still not ensured. In particular, difficulties arise in finding a compromise between the need to completely stop the blood flow from the damaged artery and the choice of means of clamping (to prevent excessive clamping) of the limb, as well as the presence of metal or plastic fasteners in the tow structure.

So, a hemostatic tourniquet is known [4], containing a base-tire, a retainer and a tensile cord connected with the retainer. The bus is made in the form of a group of sections connected by movable joints, while the movable joint of the sections is configured to fold sections into a bag and with the possibility of removing at least one section. The harness is equipped with a traction strap. The anti-traction strap is connected to the latch and to the tire section. The anti-pull webbing is made with an opening having dimensions for mating with a tensile strand with the possibility of frictional fastening of its free end. Sections are made with a lining of a volume-deformable material. The movable connection of the sections is made of a volume-deformable material. A significant drawback of this tourniquet is that there is no possibility of dosing the pressure force on the tissue, and there is the possibility of tightening the tourniquet in only one side, which is not always convenient. In general, this harness is a rather bulky and difficult to use device.

In general, hemostatic tourniquets, the design of which, as described above, provides compression only by tightening the tourniquet [5, 6], do not provide the possibility of “fine” adjustment of the compression force. At the same time, in some designs of this type, issues of preventing injury to tissues, in particular skin, are being addressed. Thus, a hemostatic tourniquet is known [7], containing elastic braid with a terry effect on one side, a device for looping the terry inward and a fixation device for the attached tourniquet. The device for looping is made in the form of a buckle-frame of a rectangular shape, and on the free end of the elastic tape is fixed a device for fixing the applied tourniquet, consisting of at least 2.5 rounds. The fixation device of the superimposed tourniquet is made in the form of a tape velcro hooks. However, with the help of a tourniquet of the described construction, it is extremely difficult to stop the bleeding, it is impossible to carry out the necessary dosed pressure on the tissues, which under conditions of excessive compression can increase the traumatic effect on the limb.

Also known is the construction of the tourniquet, which the developers position as a metered compression tourniquet containing an inextensible (in particular a fabric strap) and an extensible (in particular a rubber plate) tape, the last of which has labels that correspond to the compression force for the shoulder and lower leg - 4 , 3 kg, and for the thigh - 12.7 kg [8]. An extensible tape is connected inextricably from one end in one piece, and has a rectangular buckle on the other end, equipped with a clamping element made in the form of a movable strap. The tourniquet has a simple design and allows you to quickly apply it to a damaged limb, as well as carry out all the application operations with one hand with minimal physical effort.

The very idea of a dosed compression of a tourniquet with an indication of the “dose of squeezing force for the arm and leg” in the form of a square or circle was realized during the Second World War. However, the idea of a dosed compression of the tourniquet with the indication of “dose of squeezing force for the arm and leg” in the form of a square or circle (the principle “STRETCH UP TO SQUARE”) cannot be safely used in practice, because girth of the limbs in different people can vary significantly, both depending on age and depending on individual anthropometric data. The very principle of such a "dosage indication" grossly violates the fundamental rule of applying hemostatic tourniquets - only under the control of the pulse or until the bleeding stops completely.

Even during the years of World War II, a hemostatic tourniquet of the NIIIS RKKA with a "twist" began to be used [9]. The use of individual elements in the construction of the tourniquet, which provide initial squeezing of the limb by tightening the loop and additional adjustable squeezing due to the “twist”, made it possible to make the application of the tourniquet more controlled and minimize the negative consequences of applying the tourniquet. At the same time, the first tourniquets of this type, which can be considered a prototype of modern turnstiles, had a number of significant drawbacks: the metal (plastic) parts of the fasteners provoked the development of necrosis zones and skin injuries even through clothing, so this tourniquet can be applied only through a thick or very dense fabric; this tourniquet cannot be used in cases of limbs blocked or bulky shoes (boots, boots with wide legs, high boots, etc.) can be passed into its loop; the tourniquet is poorly washed from blood and dirt due to the large number of mounting holes and parts made of various materials (metal, rubber, plastic, fabric; if improperly or incorrectly applied, the tourniquet is very difficult to remove and re-apply; if the loop is accidentally or intentionally unhoused will be able to properly assemble the tourniquet and use it within 1-2 minutes.

In recent years, hemostatic tourniquets of a similar operating principle and similar construction have appeared in the US and Israeli armies with a significant improvement in the effectiveness and safety of the overlay, which are referred to as a “hemostatic tourniquet” or simply “turnstile”, less commonly a “tactical tourniquet” [10, 11]. The turnstile is a relatively wide ribbon made of a dense, usually synthetic material. Designed for use in extreme conditions. For the possibility of overlapping with one hand, it can be equipped with a Velcro fastener, or any other structural part that prevents the free backward movement of the belt, and a wrench with a lock to create a stronger belt tension. Also, in most cases, the design contains a "medical beacon" to indicate the time of its application. The designs of such tourniquets, according to their manufacturers, meet most of the requirements for hemostatic tourniquets, but at least two disadvantages remain: the application of these tourniquets when injuring the femoral artery in a battlefield is extremely inconvenient and entails an unreasonably large loss time; turnstiles have a fairly high cost.

By analogy with turnstiles manufactured in the USA and Israel, hemostatic tourniquets such as turnstiles, in particular, Yellow & Blue, are also produced in Ukraine [12]. This hemostatic tourniquet type tourniquet contains a belt of high strength fabric, a metal buckle with a loop, a snap hook, a plastic wrench, a turnstile pad, and a metal triangular lock. A special white label is attached at the end of the belt strip to apply information on the time of applying the tourniquet. The turnstile of the Yellow & Blue company is a belt-buckle system, which, in accordance with the application algorithm, allows to stop the blood supply to the extremities below the place of application. The design is based on the spin principle. When using the turnstile is superimposed on the damaged limb (the carabiner should be located to the victim). Next you need to pull the sling and tighten it down smoothly. If the first round of applying the turnstile is performed correctly, then the collar in a pair of half-turns blocks the blood flow. All that remains is to fix it by threading it into a metal retainer, wrap the rest of the slings around the fixed gate and record the turnstile overlay time. At the same time, the design of such a hemostatic tourniquet-type tourniquet determines some inconvenience when fixing the winch due to the use of a metal triangular retainer for these purposes. In addition, the problem of tissue injury during its application remains unresolved.

According to the results of the analysis of the prior art, the last of the considered technical solutions of a tourniquet type tourniquet in combination of essential features common with the claimed can be selected as a prototype for the claimed tourniquet type tourniquet.

Thus, the objective of the utility model is to develop the design of a tourniquet-type tourniquet tourniquet that, while retaining all the advantages of the prototype and other similar technical solutions from the prior art, would allow faster and easier passage of the belt (slings) through the buckle up to squeezing the limb with instant reliable fixation the position of the tensioned belt in the buckle, as well as the subsequent simple and quick loosening of the harness to remove it. The design should also provide easier rotation of the head with a stronger squeezing of the limb due to a slight increase in the number of revolutions of the head. In addition, the design should provide a significant reduction in pain at the junction of the movable belt with a fixed base-pad and a significant reduction in the level of trauma to compressible limb tissues when applying a tourniquet to bare skin.

The problem is solved by the inventive hemostatic tourniquet type turnstile, containing a base of high strength fabric with means for fixing the position of the collar and a carabiner placed on it, connected to the base by means of the slings of the collar, and also a belt with a buckle made with the possibility of fixing it on the base by means of a carabiner with the formation of an adjustable loop circumference. The problem is solved due to the fact that the base is made of a belt tape and, on the side intended for application to the body, at least on a part of the surface, contains a patch of elastic material that is inextricably linked to the indicated surface. A sling with a winch is fixed on the base at both ends and connected with a belt made of a belt tape through a metal frame placed on the sling with the possibility of free movement on it. In this case, the buckle is made in the form of a self-clamping buckle.

In the inventive hemostatic tourniquet, the self-tightening buckle together with an overlay of elastic material provides not only a quick tightening of the tourniquet with one hand and quick loosening of the tourniquet to be removed by pressing on the corresponding buckle structural element, but also protecting the skin at the place of application of the tourniquet from mechanical damage and pain caused by squeezing . At the same time, reliable fastening and holding of the buckle is carried out using a carabiner. One of the main design features is that a belt made of a belt tape is used to tighten the harness, which pulls the main harness belt through a metal frame. This method provides an easier rotation of the head and allows more severe squeezing of the limb due to a slight increase in the number of revolutions of the head. This also reduces pain at the junction of the belt with the pad. The use of a special design buckle in the construction of the tourniquet - a self-clamping buckle that provides easy passage of the belt up to squeezing the limb, as noted above, provides quick tightening and quick loosening of the tourniquet with one hand.

In preferred embodiments of the inventive hemostatic patch strip on the base can be made in the form of rows of latex threads evenly spaced across the entire width of the base. This ensures a safe and painless contact of the base with the skin after during application and after application of the tourniquet.

It has already been noted above that a self-clamping buckle is used in the design of the inventive hemostatic tourniquet. As a rule, a self-clamping buckle consists of two parts that ensure the belt locks with an increase in compression force. In preferred forms of implementation of the inventive hemostatic braid, the self-tightening buckle consists of a hingedly connected frame and a gear lock with a hole for fastening in the carbine. The presence of a pivotally interconnected frame and a gear lock provides a simple and reliable locking of the belt after applying the harness in the tightened position. At the same time, fixing by means of gear elements provides a simple and quick loosening of the belt and the harness as a whole until the removal of the harness.

In preferred forms of implementing the inventive hemostatic means of fixation of the position of the collar is made integral and contains a metal bracket fixed to the belt of the belt base with beveled edges and a safety tape made with the possibility of its removable fixation on the bracket. The use of a bracket with chamfered edges in the fixation of the position of the collar of the collar allows the simple insertion (due to the bevel) of one of the collar arms under the bracket, followed by reliable holding of the collar by means of at least one of the end flanges of the bracket. At the same time, the presence of two shelves symmetrically located relative to the longitudinal axis of the base of the bundle, with bevels symmetrically located relative to the longitudinal axis of the base of the bundle, provides the possibility of simple and reliable fixation of the collar during its rotation both around the clockwise and counterclockwise.

The security tape in the composite means for fixing the position of the collar, at least on a part of its surface, can preferably be made in the form of a loop tape, while at least on a part of the outer surface of the bracket there are sections provided with a hook tape. At the same time, the size and location of the loop tape on the safety tape and the hook tape on the bracket are selected with the possibility, after applying the tourniquet and placing the collar in the bracket, to fix the safety tape using the formed Velcro fastener (textile fastener) with the gap between the end sections of the bracket overlapping , which provides an additional fixation to the bracket clamp. The described implementation of the safety tape makes it possible to easily replace it in cases of repeated use of the harness.

Taking into account the possibility of replacing the safety tape when reusing the harness, and also taking into account the general requirements for applying the harness, a field is provided on the safety tape for recording information about the time the harness was applied.

In preferred embodiments of the inventive styptic tourniquet, the safety tape is capable of being completely replaced after use by pulling it from under the bracket and installing a new one.

As part of the inventive hemostatic braid, the self-clamping buckle is preferably made of metal, preferably of stainless steel. This form of execution almost completely eliminates the possibility of breakage of the buckle when applying the harness and loosening the belt, and thereby ensures high reliability of the harness as a whole.

Also, to increase the reliability of the tow in preferred forms of its implementation, the door is made of metal, preferably of aluminum alloy.

The above and other advantages and advantages of the inventive hemostatic tourniquet will be considered further on the example of one of the possible preferred, but not limiting forms of implementation with reference to the positions of the figures of the drawings, which schematically depict:

The tourniquet contains a base 1 made of high-strength fabric with a means for fixing the position of the collar and a carabiner 2. The tourniquet also includes a collar 4 connected to the base 1 by means of a sling 3, and also a belt 5 with a buckle 6 made with the possibility of fixing it on the base 1 by means of a carabiner 2 with the formation of a loop adjustable in circumference.

The base is made of a belt tape and from the side intended to be applied to the body, at least on a part of the surface, contains a patch 7 made of an elastic material that is integrally connected to the indicated surface. A sling 3 with a collar 4 is fixed on the base 1 by both ends and connected with a belt 5 made of a belt tape through a metal frame 8 that can be freely moved along it on the sling 3.

The overlay 7 on the base 1 in the implementation form presented in the drawings is made in the form of rows of latex threads 9 (shown in Fig. 9 schematically in the form of circles) uniformly spaced across the entire width of the base 1.

The collar 4 is made of metal, preferably from an aluminum alloy and has two symmetrically located shoulders 10.

The means for fixing the position of the collar 4 in the implementation form shown in the drawings is made integral and comprises a metal bracket 11 with beveled edges 12 fixed to the belt base belt 1 and a safety tape 13 made with the possibility of its removable fixing on the bracket 11.

The size and location of the loop tape 14 on the safety tape 13 and the hook tape 15 on the bracket 11 are selected so that after applying the tourniquet and placing the collar 4 (one of the shoulders 10 of the collar 4) in the bracket 11, the loop tape 14 and the hook tape 15 are formed Velcro fastener with a gap between the end sections (chamfered edges 12) of the bracket 11. The security tape 13 has a field 16 for recording information about the time the tourniquet was applied (indicated by a dash-dot line).

In the embodiment of FIG. 5-FIG. 7, for an example implementation form, the buckle 6 consists of a frame 19 and a gear lock 20 with an opening 21 for fastening in a carabiner 2 interconnected by a swivel 22. The buckle is made of metal, preferably stainless steel.

In FIG. 5 arrows indicate the direction of movement of the belt 5 when applying a tourniquet (tightening the loop on the limbs).

The inventive hemostatic tourniquet type turnstile is superimposed and operates as follows.

The inventive styptic tourniquet type of tourniquet relates to devices for temporarily stopping bleeding from a damaged limb. As a rule, a tourniquet is used for significant arterial bleeding, applying it above the damaged area: for injuring the lower limb - at any level of the thigh, for injuring the upper limb - on the shoulder, except for its middle third, where there is a danger of compression of the nerve trunks. The styptic tourniquet is supplied and completed with first aid in folded and packaged form. If it becomes necessary to use it (bleeding, including arterial bleeding in the region of the extremities), the tourniquet is removed from the package, turned around and the base 1 is wrapped around the limb with a patch 7 made of elastic material (in the presented example, the patch is made in the form of rows of latex threads 9, evenly spaced across the entire width of the base) to the body. The tourniquet can be applied both on bare skin and immediately on clothing, since due to its construction, in the first case, pain in zones 17, in which skin injuries usually occur in harnesses known from the prior art, and the likelihood of crushing injuries, are minimized limb tissues, and, in the second case, created with the help of a collar, 4 adjustable and controlled efforts are enough for a correct and safe stop of bleeding. Next, the self-locking buckle 6 is snapped using the hole 21 for mounting on the carabiner, in the carabiner 2 located on the base 1 and with a strong force is pulled by the end of the belt 5, tightening the resulting loop. Reliable fastening and retention of the buckle 6 is provided with a carabiner 2. At the same time, when pulling the belt 5 through the buckle 6, thanks to its design, the belt 5 can easily pass up to squeezing the limbs, with the frame 19 and the gear lock 20, interconnected by a swivel 22 , when the belt 5 passes through the buckle, it is locked, which increases as the compressive force increases. In addition, when applying the tourniquet, both on bare skin and on clothing, a simple, convenient and quick preliminary fixation of the tourniquet on the limbs, in combination with the design features of the buckle 6, is also provided by an overlay 7 of elastic material (in particular, in the form of rows of latex threads evenly spaced across the entire width of the base 1) of the base 1. Thus, under any conditions of application of the tourniquet, there is no need to perform any separate additional manipulations to pre-fix the tourniquet on the limbs, d only after the effort to pull the end of the belt 5, and the resulting loop provides a tight hold of the base 1 with the lining 7 to the limb (directly or through clothing).

Then rotate the knob 4 in any direction to twist the slings 3 until the bleeding stops (under the control of the pulse). In this case, the tightening of the tourniquet is carried out not by tightening the belt 5, but by tightening the sling 3, which is connected through the metal frame 8 to the belt 5. The sling 3 is passed through the frame 8 and connected to the base 1 at the 18 fastening points with both ends of it 1. The belt 5 is also passed through a metal frame 8, and its end is fixed in place 18 bonding by firmware. Tightening the tourniquet due to the sling 3 provides easier rotation of the lever 4 and stronger compression of the limbs, with the same twisting force of the lever compared to the known analogues, due to a slight increase in the number of revolutions of the lever 4. This also minimizes pain in zone 17 skin injury, which corresponds to the junction of the slings 3 with the base 1 with the pad 7.

After stopping the bleeding, the position of the collar 4 is fixed by placing its shoulder 10, located as a result of rotation from the side of the bracket 11, under the corresponding shelf of the metal bracket 11. Moreover, due to the execution of its edges 12 beveled, the shoulder 10 of the collar 4, located at an angle to the bracket 11 easily passes into the gap between the chamfered edges 12 of the bracket 11. After fixing the collar 4 in the bracket 11, using the Velcro fastener, disconnect the end of the safety tape 13 and glue the bracket 11 with it, aligning and bringing into contact the corresponding sections safety tape 13, equipped with a loop tape 14 with sections of the bracket 11, provided with a hook tape 15. The remaining part of the bundle is fixed inside the loop.

After completing all the above steps, the tourniquet is superimposed. After applying the tourniquet, the pulse on the peripheral vein is controlled - it should be absent. In the field 16 for recording information about the application time of the harness of the safety tape 13, the application time of the harness is recorded.

To remove the harness, just pull the frame 19 of the buckle 6, as a result of which the frame 19 of the buckle 6 rotates around the axis of the swivel joint 22 and the toothed lock 20 of the buckle 6 comes out of the pressure contact with it, thereby eliminating the locking effect on the belt 5, which easily "slides" between the open frame 19 and the gear lock 20, loosening the loop around the limb until it can be easily removed from the limb.

To remove the harness with the Velcro fastener, the safety tape 13 is unfastened, opening the gap between the beveled edges 12 of the bracket 11, the shoulder 10 of the collar 4 is pulled out of the bracket 11 and the sling 3 is loosened by rotation of the collar 4 and the harness as a whole.

The used safety tape 13 is removed from the used and removed from the extremity tourniquet with the Velcro fastener by pulling it out from under the staple 11, and the tourniquet is sent for washing / cleaning / sanitation, etc.

For reuse, a new safety tape 13 is installed on the harness that has undergone the necessary processing, and it is secured with a Velcro fastener under the bracket 11. The harness is folded and, if necessary, packaged.

Thus, the inventive hemostatic tourniquet type of turnstile provides a simple, quick, effective and safe application, including independent, both on bare skin and clothing in any conditions (light, ambient temperature, etc.).
