Description

The utility model relates to medicine, namely to dressings, and can be used to provide first aid for wounds.

The proposed device is used to apply a tight pressure bandage on cuts and other violations of the patient's bodily integument with a violation of the integrity of the veins, capillaries, as well as bleeding from small arteries. One of the first aid methods for these injuries is the application of a tight pressure bandage, which reduces bleeding from the damaged vessel, accelerates the appearance of a blood clot at the site of injury and, ultimately, reduces blood loss and stops bleeding.

Historically, in domestic dressing bags, a gauze-cotton lining (pillow) is used as an absorbent pad, which absorbs blood well, provides wound thrombosis, and a gauze bandage is used as a dressing. The absorbent pad creates peace for the wound and conditions for a continuous and uniform outflow of fluid from it into the external environment, distributing absorption over the entire surface, and also promotes self-cleaning of the wound. The use of such a dressing bag for applying a tight pressure bandage is quite acceptable, but the initial pressure of the dressing on the wound, provided by a gauze bandage, decreases after a short time. This disadvantage is compensated by the imposition of a large number of dressing rounds on the bleeding site. In addition, with insufficient bandage pressure, it will take a long time for the wound to thrombose.

Currently, an elastic pressure bandage is used as a dressing instead of a bandage. It is used as a secondary sterile wrap for bandaging, as well as an additional sorption layer to absorb excess blood. Thanks to a special cut and vertical stitching, the dressing is elastic only in length, not in width. This allows the bandage to "sit" tightly on the limb and not move out of the wound. At the same time, due to the possibility of stretching the material in length, it is possible to choose the "degree of winding": either tighten the wound more strongly, or cover a large area of the limb, or wind it more tightly in one place. This elasticity provides a significantly better effect on the site of bleeding. It should be noted that the excessive force provided by the elastic band, with a long time of exposure to the affected organ, may well cause harm, disrupting the natural supply of blood to the organ for a long time. In addition, this method requires special knowledge and a quiet environment to ensure the correct level of compression.

Long-term use in world practice as a bandage dressing package with a polymer product (pressure applicator) attached to an elastic band that provides increased pressure on the wound (Israeli compression bandage). This approach is effective in stopping bleeding in the shortest possible time. The pressure applicator is a half-moon-shaped plastic support and a bracket, which can be used to fix part of the tissue during rewinding and fix the free end of the dressing. By means of the pressure applicator, a pulling force constantly acts on the wound, tightly pressing the bandage against the wound. It is believed that the fixator allows you to quickly create pressure equivalent to the imposition of gravity weighing up to 14 kg. When properly applied, the bandage provides and maintains a stable pressure action up to 14 kg. In the specified design of the specified dressing package, in addition to positive factors of influence, there is also a slight drawback. This is a small area of impact of the specified insert, which, when applied to a wound of a large area, it affects only a certain part of the wound cavity, and not the entire area of the wound.

Among the analogues of dressing packages known today, there are no such that solve the problems of applying a pressure bandage in a complex:

- tight pressing of the absorbent pad to the wound channel over its entire area;

- increased area of the pressure applicator and the area of impact on the wound;

- convenient positioning of the dressing bag pressure applicator on the wound area;

- convenient fixation of the edge of the dressing tape.

Thus, an individual medical dressing package with an elastic bandage is known (https://yandex.ru/patents/doc/RU208284U1_20211213), including a fixed pad, a pad configured to move along the length of the bandage with the help of an overlay fixed on its wrong side, worn around elastic bandage, as well as a clasp at the far end from the fixed pad. The clasp is made at the end of the elastic bandage and has a width of 2 to 2.5 cm and a length equal to the width of the elastic bandage.

The specified dressing medical package ensures the work of a tight pressure bandage solely due to the elasticity of the dressing. It should be noted that the excessive force provided by the elastic band, with a long time of exposure to the affected organ, may well cause harm, disrupting the natural supply of blood to the organ for a long time.

Known dressing material (https://yandex.ru/patents/doc/RU88961U1_20091127), including a substrate and a sorbent, is characterized in that the sorbent is made in the form of a calcium alginate tampon, over which a substrate is placed, equipped with fixing tapes protruding beyond the area of the substrate, one side of which is made sticky, for example, with adhesive tape, while the volume of the tampon corresponds to the volume of the wound cavity, provided it is densely filled, and the area of the substrate exceeds the area of the surgical wound at the level of the skin.

The proposed technical solution is a dressing that does not include a pillow. This tool is a tampon of considerable size, to which drugs are added. Such a device can be used for treatment, but not for use in extreme conditions.

An individual dressing package is also known (https://yandex.ru/patents/doc/RU111433U1_20111220), which includes packaging, an anatomically shaped transport tire, and a dressing kit. The dressing set contains a fixation element made in the form of a bent bracket with a ribbed surface, and an atraumatic-sorption pad fixed motionlessly on a fixing elastic bandage. It also includes a crescent-shaped pressure pad with a hole for pulling the bandage placed on the reverse side of the pad, and the fixation element is made in the form of a bent bracket with a ribbed surface.

The disadvantages of this dressing package include the need for precise positioning of the pressure applicator when applied to the wound. In addition, the area of pressure impact on the wound is negligible. All this greatly complicates the use of such a device in extreme conditions, where the speed and convenience of applying a dressing to a wound play a significant role.

The closest to the claimed device is (https://yandex.ru/patents/doc/RU111432U1_20111220) an individual dressing package, including a fixation element made in the form of a bent bracket with a ribbed surface and two atraumatic-sorption pads, one of the pads is fixed motionless on fixing elastic bandage, and the second with the ability to move. It also includes a crescent-shaped pressure pad (pressure applicator) with a hole for pulling the bandage placed on the reverse side of the fixed pad, and the fixation element is made in the form of a bent bracket with a ribbed surface.

The disadvantages of the above technical solution include the inconvenience and complexity of its use (increased dimensions of the product), which significantly affects the speed and, in some cases, the ability to provide first aid for injuries. Also, the above factors are negatively affected by a complex fixation mechanism.

At the moment, the technical problem is the implementation of a convenient and easy-to-use dressing package that provides in combination:

- convenient application and positioning of the material of the dressing bag in the wound area (taking into account the condition of the victim);

- ensuring the imposition of a tight bandage on the wounded area, with dosed pressure, which ensures both stopping the bleeding and not interfering with the natural blood supply to the organ in the future;

- intuitive or simple overlay mechanism;

- ensuring a tight pressing of the absorbent pad to the wound channel over its entire area;

- increased area of the pressure applicator and the area of impact on the wound.

The technical result consists in increasing the convenience and ease of use of the dressing bag while ensuring effective bleeding control.

The technical result is achieved by the fact that in the dressing bag, which includes a bandage, an absorbent pad located on it, as well as a clamping mechanism, including a plastic plate and an arc, the central part of which is rotatably located on a plastic plate connected to the bandage, according to the utility model, between the bandage and the absorbent pad is a silicone pad, the area of which exceeds the area of the absorbent pad, and the clamping mechanism includes two arcs, the edges of which are oriented in different directions.

In a preferred embodiment of the utility model, the device comprises a clamp-like fixation mechanism located on the bandage.

The proposed design is quite convenient and provides the ability to simply and quickly stop bleeding under extreme conditions.

The dressing package includes a bandage 1, as well as a clamping mechanism, including a plastic plate 2 and two arches 4. The plastic plate 2 is equipped with a base for attaching the arches. The edges of the arcs 4 are oriented in different directions. Also, the dressing package includes an absorbent pad (not shown in the drawings) located on the bandage on the reverse side of the plastic plate, and a silicone pad 3.

Preferably, the claimed device is made of the following materials.

As a bandage, a medical elastic fixing bandage "Meditek", TU21 20 24-002-54783613-2017, Reg. beats No. Р3Н2018/7984 dated December 25, 2018. Also, a medical elastic fixing bandage can be used, width 10 cm, length 700 cm, LENTA OJSC, Republic of Belarus, article 09S8008 / 7P-G50, width 10 cm, length 350 cm, TECHNICAL DESCRIPTION STB 2144-2010 / TO BY 700002794.667-2011.

The pads made of soft silicone are well fixed on dry and clean skin, and do not dry on the wet surface of the wound. Thanks to this, their change is painless. The silicone layer allows you to maintain a moderately moist environment on the wound surface. Silicone is an eco-friendly and hypoallergenic material, which rarely causes an allergic reaction. Also, the plate can be made of sevilen. It is a material with a unique compatibility with various substances (adhesion).

Any polymer with structural rigidity, operating temperature from minus 50°C to 50°C, and pour point not higher than 140°C can be used as a material for the manufacture of a pressure applicator (plastic plate and arcs). In addition, the specified material must comply with FDA standards, which means that it can be used in medicine.

As absorbent pads, it is preferable to use a composition of non-woven materials with different properties in terms of liquid absorption. The first layer perfectly passes the liquid and evenly distributes it over the bag, the second one based on fluff pulp provides absorbency and liquid retention. The third does not allow moisture to pass through and ensures minimal fluid flow.

The claimed device works as follows.

After removing the packaging, the absorbent pad attached to the bandage, together with the clamping mechanism, is applied to the wound channel 6 (Fig. 2). With one hand, holding the silicone plate, perform the first round with a bandage and fix the plate on one side 7 (Fig. 2). Performing the second round with a bandage 8 (Fig. 3), an absorbent napkin with a silicone plate 9 (Fig. 3) is fixed on the wound cavity. Further, the free end of the bandage 10 (Fig. 4) is moved up 11 (Fig. 5), towards one of the two arcs 12 (Fig. 5) of the pressure plate, the bandage is threaded into a special gap of the arc and the direction of movement of the bandage is changed to the opposite . Performing the third round of the bandage 11 (Fig. 6), in the direction of the second arc of the pressure plate 13 (Fig. 6). The bandage is threaded into the lumen of the second arc and the direction of movement of the bandage changes again. The changes in the direction of bandage movement described above provide the effect of pressing the napkin, the silicone plate and the pressing mechanism against the wound cavity. By adjusting the tension of the bandage, the arcs of the clamping mechanism rotate on axis 14 (Fig. 6) to provide clamping with the necessary force. The rest of the bandage is wound around the applied pressure bandage, ensuring its further fixation and absorption of bleeding from the wound.

The claimed utility model is illustrated by examples.
