Description

The device relates to medicine, namely to emergency conditions, and can be used to stop massive bleeding in first aid.

Bleeding that occurs in everyday life, as a result of high-energy injuries involving mechanisms, during the period of hostilities are life-threatening, require immediate action aimed at the implementation of hemostasis and the prevention of fatal blood loss.

According to experts, about 10 million accidents occur annually in Europe alone, while about two percent of the injured die from traumatic injuries with unstopped massive blood loss.

Mechanical methods for stopping bleeding, which involve the application of tourniquets, have a number of significant drawbacks. In particular, it can be difficult to apply a tourniquet on your own in case of injury, it is not possible to apply a tourniquet on any part of the body, excessive compression and traumatization of damaged tissues have negative consequences that can exceed the achieved hemostatic effect.

Devices are known, for example, Xstat-30, which is a plastic syringe filled with 92 small sponges. In the event of massive bleeding, it is used to inject directly into the wound, and after 20 seconds the bleeding stops [found on the Internet https://www.techcult.ru/gadgets/2839-shpric-xstat, accessed 12/25/2021].

Disadvantages of the device - the body of the syringe is made of hard plastic, which can cause additional injury to the victim due to the introduction of a hard object into the wound hole.

The Celox-A applicator is known [found on the Internet http://www.celoxmedical.ru/what/, accessed 12/25/2021].

The device is shaped like a syringe, the applicator contains Celox granules, which guarantees maximum efficiency and reliability of the product. However, the inflexible shape can cause additional injury when the device is inserted into the wound. In addition, when opening the package, you must independently remove the plug and insert the piston into the applicator body, which can cause significant difficulties in conditions of pain shock caused by injury or injury to the working hand, for example, the right one.

The technical result that can be implemented using the developed device is a quick, self-executed by a wounded person introduction of the applicator into the wound channel and the release of hemostatic agent granules into it, which does not require concentration and coordination of movements.

The device consists of a piston (1), hemostatic beads (2) that are inside the body (3), an outlet (4) for hemostatic beads, a perforated cap tear line (5) to which a cap (6) is attached, and a tape for tear off the cap (7). The device is in a sterile package (8) with a lid (9) to which a tape is attached to tear off the cap (7).

The device works as follows. The lid of the package (9) is opened, the action can be performed both with the free hand and, for example, with the teeth. In this case, the cap tearing tape (7), which is attached to the package lid (9), is torn off along the perforated line (5) and tears off the cap. Then the outlet (4) is aligned with the outer opening of the wound channel, the body of the device (3) is immersed in the wound, as far as the size of the wound allows. Press on the piston (1) and move the hemostatic granules (2) into the wound cavity.

The hemostatic granules (2) can be made from a biomaterial having antibacterial and biodegradable properties, such as chitosan. The size of hemostatic granules (2) should not exceed 1/10 of the size of the outlet (4), which makes it possible to move the granules (2) into the wound channel almost spontaneously, without applying significant physical effort. The hemostatic applicator is intended for single use and is not subject to subsequent sterilization. The piston (1) is inserted into the housing (3) in the initial non-working state. The body (3) and the piston (1) are made of soft plastic material, for example, silicone, which does not injure the wound channel when the applicator body (3) is inserted.

A cap (6) is provided in the area of the applicator outlet (4), which prevents the hemostatic granules (2) from leaving the applicator body (3) until the perforated tape (7) is torn off. The size of the outlet (4) is at least 1/3 of the diameter of the piston (1). The cap (6) is attached to the applicator body (3) by means of a cap tearing tape (7), which is connected to the body (3) along a perforated line (5). The cap tearing tape (7) is attached to the lid (9), which makes it possible to bring the device into operation simultaneously with opening the package (8).

The hemostatic applicator is packed in a sterile package (8) made of polymeric material. The packaging contains the labeling of the shelf life, brief instructions for use, recommended storage conditions.

The hemostatic applicator is designed for single use, not reusable.

The device does not need to provide special conditions during transportation.
