Description

The utility model relates to medical devices, namely to local dressings designed to quickly stop external arterial and venous bleeding of various intensities, namely to compression bandages that provide strong compression, intended for use in the field.

A device for hemostasis is known (Device for hemostasis: utility model patent No. 81641, Russian Federation, application No. RU 2008111347, application. March 24, 2008, publ. March 27, 2009). A device for hemostasis (compression dressing) containing pressure and fixing elements located on the inguinal region of the patient, characterized in that the fixing element is made in the form of an inextensible tape with a clamp, equipped with two pull-up tape elements and supplemented with length clamps located in the outer surface of the thigh and in the inguinal region and combined with the patient's waist belt. In this case, the pressure element is made of poorly deformed low absorbency, as well as biologically and chemically inert material (presumably from expanded polystyrene).

The disadvantage of this device is the relatively low efficiency of maintaining a given level of compression for a long time. This is due to the lack of a compression indicator, which does not allow you to control the level of compression during dressing and after transportation of the wounded to the hospitalization site. In addition, the known dressing is narrowly targeted and cannot be used for injuring various parts of the body (for example, upper limbs).

Known compression dressing (Compression dressing and method of its manufacture: application No. RU 2013157083, Russian Federation, application. 05.29.2012, publ. 07.20.2015). This compression dressing contains an inner surface and an outer surface representing a multilayer structure. The multilayer structure includes an elastic inner layer forming said inner surface and intended to come into contact with the skin, the elastic inner layer being hydrophilic, not sticking to the skin and made of absorbent material. Also, the multilayer structure includes an elastic intermediate layer, permeable to gases and impermeable to liquids, in addition, the multilayer structure includes a flexible outer layer forming said outer surface. In this case, the multilayer structure has at least a first and a second edge, located generally opposite to each other, and connecting elements connecting to each other at the first and second edge to close the dressing in the form of one turn on a part of the body.

The disadvantage of this device is the relatively low efficiency of maintaining a given level of compression for a long time. This is due to the lack of a compression indicator, which does not allow you to control the level of compression during dressing and after transportation of the wounded to the hospitalization site. In addition, the known dressing is quite difficult to use, and its improper application can increase the risk of complications when transporting the wounded to the place of qualified care.

Known adaptive compression hemostatic dressing (Adaptive compression hemostatic dressing: utility model patent No. 58353, Russian Federation, application No. RU 2006119949, published 06.06.2006, publ. 11.27.2006). The dressing is a bandage, in the form of a tape with two head-rollers, made of hygroscopic matter with different extensibility of the edges in length and constant in width. The dressing is impregnated with a medicinal composition. The dressing provides an effective application to the wound with crossed bilateral descending (from the center to the periphery) spiral passages with controlled local mechanical pressure on the tissue, rolling the rollers towards each other, eliminating circular turns throughout the formation of the dressing.

The disadvantage of this device is the relatively low efficiency of maintaining a given level of compression for a long time. This is due to the lack of a compression indicator, which does not allow you to control the level of compression during dressing and after transportation of the wounded to the hospitalization site. In addition, the known dressing is quite difficult to use, and its improper application can increase the risk of complications when transporting the wounded to the place of qualified care.

A technical problem is the development of a compression bandage that is easy to use, durable and resistant to environmental factors, allowing you to quickly and reliably stop external arterial and venous bleeding of various intensities, and also can minimize the risk of complications arising from the transportation of the wounded to the hospital.

The technical result consists in increasing the efficiency of maintaining a given level of compression for a long time at the stage of first aid to the wounded.

The technical result is achieved by the fact that the compression bandage, consisting of a base, as well as a contact tape, a pressure applicator, a sorption pad and a fixation device located on the base, according to the utility model further comprises a compression indicator located on the base, the base being made of elastic cotton fabric, the sorption pad is made of bicomponent staple fiber, and the contact tape is made of polyamide.

The location of the compression indicator on the basis of the bandage is due to the need to control the level of compression for a long time, since at the stage of first aid when transporting the wounded to the place of qualified medical care, the bandage may shift, which leads to a change in the level of compression. The most reliable option is to perform a compression indicator of textile material in the form of a geometric figure that changes shape when the compression level changes.

The implementation of the basics of elastic cotton fabric is due to the sufficiently high strength of this material against a background of high air permeability. Strength is necessary to keep the dressing intact during first aid in the field, since when the canvas breaks, it is impossible to provide the necessary level of compression. Due to air conduction, air is circulated between the body and the environment.

The implementation of the sorption cushion of a bicomponent staple fiber due to the high strength and sorption properties of this material.

The implementation of the contact tape made of polyamide is due to the high wear resistance and a wide range of application of the contact tape made of this material, this allows you to securely fasten the product with the optimal level of compression and keep it for a long time. Moreover, the execution of the contact tape in the form of rectangular sections located on the entire surface of the outer side of the base perpendicular to its longitudinal axis at an equal distance from each other allows you to fix the bandage after each revolution around the body part of the wounded to the next round of its base.

Thus, the above modifications provide the maintenance of a given level of compression for a long time.

The claimed technical solution is illustrated by the drawing, where in FIG. A compression bandage is presented in general form from the outside (not intended for contact with the body).

Compression bandage includes a base 1, made in the form of a bandage of elastic cotton fiber, and located on it from one edge of the inner side (intended for contact with the body) sorption pad 2, made of bicomponent staple fiber. On the basis of 1 from the outside (not intended for contact with the body) is a pressure applicator 3 made in the form of a rolled up medical bandage made of cotton, fixed on the base 1 with a textile seam. In this case, the pressure applicator 3 is located on the same section of the base 1 as the sorption pad 2, but from the opposite, that is, from the outside. In addition, on the basis of 1 on the outside there is a tape-contact 4, which is fixed on the basis of 1 textile seam. In a preferred embodiment of the utility model, the tape-contact 4 is made in the form of rectangular sections located on the entire surface of the outer side of the base 1 perpendicular to its longitudinal axis at an equal distance from each other. On the opposite to the sorption cushion 2 edge of the base 1, there is a fixation device 5 on the outside, which is fixed to the base 1 with a textile seam. In a preferred embodiment of the utility model, the locking device 5 is made in the form of a plastic fixing bracket. On the basis of 1 there is a compression indicator 6 made of brightly colored textile material, which is a geometric figure that changes shape when the level of stretching (during application) and the subsequent compression change. The compression indicator 6 is fixed on the basis of 1 textile seam. In a preferred embodiment of the utility model on the basis of 1, several compression indicators 6 are located, which are made of brightly colored elastic cotton fiber and are located on the basis of 1 on both sides at an equal distance from each other. At the same time, in the preferred embodiment of the utility model, the compression indicator 6 is a rectangle made of elastic cotton fiber and located on the base 1 so that when stretching the base 1 to a certain state, which provides the necessary compression level when applying the bandage to the body (24 -40 mm Hg), changes its shape to a square.

The claimed technical solution works as follows.

Open the package and holding the free edge of the dressing, place it with the sorption pad 2 down (on the wound), while the pressure applicator 3 is located on the opposite side of the pad and is a means of local pressure on the wound. Then, assisting, holding part of the dressing with a sorption pad 2, stretches the base 1 from the side of the fixation device 5 and in a circular rounds puts a bandage around the damaged part of the body of the wounded. During the application of the bandage dressing, the tape-contact 4 clings to the base 1 and fixes it with each subsequent turn to the next round of its base. At the optimal compression level of the bandage, the compression indicator 6 takes the form of a square. If the compression level is insufficient or excessive, the compression indicator 6 has the shape of a rectangle. In case of excessive tension, the bandage should be loosened, for this purpose, the provider opens the bandage one revolution or more and repeats the revolution with reduced tension of the base 1. In case of insufficient tension, the bandage should be unfastened one revolution or more and repeat the revolution, while increasing tension of the base 1. The free edge of the base 2 should be secured with a fixing device 5. During transportation of the wounded to the hospitalization site, it is necessary to monitor the level of compression using the comp SMAI 6 and pulsation control of major arteries downstream (distal) superimposed dressing. If necessary, adjust the compression ratio of the bandage.

The inventive utility model is illustrated by examples.

Example 1

Experimental studies have been conducted of the effectiveness of a compression bandage in one of the options for implementation, namely, to stop bleeding of the extremities. The experiment was conducted in a specialized room, where there is the necessary material and technical support and trained qualified personnel. A specialist in ultrasound diagnostics performed a scan of the great vessels in the region of the upper limb in a volunteer. Registered the initial values of venous blood flow in the upper limb. In order to objectively assess the degree of external compression on the underlying tissues caused by the application of a bandage bandage to stop bleeding of the extremities, a digital stand (with strain gauges) was used to objectively measure the pressure in units. (mmHg.). To apply a bandage in the area of the volunteer's right shoulder, the upper limb was freed from clothing. The inventive dressing was removed from the packaging. Holding the free edge of the bandage with one hand, the elastic cloth was applied with a pillow down (to the skin), the bandage was placed on the opposite side, the bandage was stretched and circular rounds were applied in the shoulder area, each round overlapped the previous one by 50.0%. The free end of the bandage was fixed for the previous round with a staple. The strain gauges of the digital stand were placed under the lower round of the dressing for recording external compression. The criterion for sufficient compression of the bandage on the underlying tissue is the recorded value of P - 24-40 mm Hg. A volunteer with bandage applied was lying in a prone position on a hard surface (operating table, medical ottoman). A specialist in ultrasound diagnostics using an ultrasound apparatus, scanned the great vessels in the area of the free left upper limb, and then in the area of the right (with a bandage applied) and subsequently recorded the data. As a result of measurements made before applying the dressing, immediately after and 35 minutes after application, it was revealed that as a result of applying the dressing in the shoulder region, venous blood flow in the region of the brachial veins was stopped with arterial blood flow preserved. This indicates the effectiveness of the claimed compression bandage.

Volunteers, on the basis of subjective sensations that they experienced after applying a compression bandage, evaluated the severity of pain on an analogue pain scale (from 1 to 10) 10 and 30 minutes after applying a bandage in the shoulder area. Volunteers: on the basis of the subjective sensations that they experienced after applying the bandage, assessed the severity of local and general changes (the severity of a violation of peripheral blood flow: numbness, paresthesia, the degree of violation of peripheral sensitivity).

As a result of preliminary tests carried out under the same conditions, on adequate biological models to evaluate the effectiveness of prototypes, 5 compression bandage dressings for stopping bleeding of the extremities established:

- compression bandage to stop bleeding of the extremities provides the compression class specified in accordance with the tactical and technical task 3 - strong (pressure on the underlying tissue is 24-40 mm Hg);

- compression bandage to stop bleeding of the extremities provides stopping of venous blood flow along the main veins of the extremities with preserved arterial blood flow;

- compression bandage to stop bleeding of the extremities does not cause the severity of local and general changes and undesirable phenomena, the severity of pain (on an analogue pain scale) within acceptable values, can be used in the order of self and mutual assistance.

Example 2

Experimental studies of the effectiveness of a compression bandage in one embodiment were carried out, namely, a universal bandage to stop bleeding. The experiment was conducted in a specialized room, where there is the necessary material and technical support and trained qualified personnel. A specialist in ultrasound diagnostics performed a scan of the great vessels in the lower extremity of a volunteer. Recorded baseline values of venous blood flow in the lower limb. In order to objectively assess the degree of external compression on the underlying tissues caused by the application of a bandage bandage to stop bleeding of the extremities, a digital stand (with strain gauges) was used to objectively measure the pressure in units. (mmHg.). To apply a bandage in the left thigh area of a volunteer, the lower limb was freed from clothing. The inventive dressing was removed from the packaging. With one hand, holding the free edge of the bandage, the elastic web was placed with a pillow down (to the skin), the bandage - the pelot is located on the opposite side. The bandage cloth was stretched and imposed in circular rounds in the hip area, each round overlapped the previous one by 50.0%. The free end of the bandage was fixed for the previous round with a staple. The strain gauges of the digital stand were placed under the lower round of the dressing for recording external compression. The criterion for sufficient compression of the bandage on the underlying tissue was the recorded value of P - 24-40 mm RT. The volunteer with bandage applied was lying in a prone position on a hard surface (operating table, medical ottoman). A specialist in ultrasound diagnostics using an ultrasound machine, scanned the great vessels in the region of the free right lower limb, and then in the region of the left (with a bandage applied) and subsequently recorded the data. As a result of measurements taken before applying the dressing, immediately after and 35 minutes after application, it was revealed that as a result of applying the dressing in the shoulder region, venous blood flow in the venous blood flow was stopped, while the arterial blood flow (in the femoral artery) was preserved. This indicates the effectiveness of the claimed compression bandage.

Volunteers, on the basis of subjective sensations that they experienced after applying a compression bandage, evaluated the severity of pain on an analogue pain scale (1 to 10) 10 and 30 minutes after applying a bandage in the hip area. Volunteers: on the basis of the subjective sensations that they experienced after applying the bandage, assessed the severity of local and general changes (the severity of a violation of peripheral blood flow: numbness, paresthesia, the degree of violation of peripheral sensitivity).

As a result of the preliminary tests carried out under the same conditions, on adequate biological models to assess the effectiveness of prototypes, 5 compression bandage dressings for stopping bleeding were found to be universal:

- the compression bandage bandage for stopping bleeding universal provides the compression class specified in accordance with the tactical and technical task 3 — strong (pressure on the underlying tissue is 24-40 mm Hg);

- compression bandage to stop bleeding universal provides stopping of venous blood flow along the main veins of the lower extremity with preserved arterial blood flow;

- the compression bandage for stopping bleeding universal does not cause the severity of local and general changes and undesirable phenomena, the severity of pain (on an analogue pain scale) within acceptable values, can be used in the order of self and mutual assistance
