Description

The utility model relates to medical equipment, namely to devices for local wound treatment, and is intended for sanitation of purulent wounds, fistulas, as well as for isolated treatment of body parts with bubbling foam solution.

Today, in medical, in particular in surgical practice, methods of physical antiseptics in the form of sanitation are common, based on the effect on the affected area of an antiseptic liquid, previously saturated with a certain gas. This technique allows to enhance the effect of the antiseptic due to the formation of gas bubbles and the mechanical separation of dense and viscous necrotic masses, detritus, sequesters from the focus of inflammation or the wound surface. The use of foam and soap solutions in surgical practice promotes the adsorption of contaminants, microorganisms, bacterial toxins, necrotic and decayed tissue areas on the wound surface. As a result, an unfavorable environment for the development of pathogenic microflora is created, the absorption of bacteria and toxic products of tissue protein decay is sharply reduced, the biological activity of the cells of the physiological connective tissue system is increased, self-cleaning of the wound and the development of healthy granulations are accelerated.

A known method for the treatment of pyoinflammatory processes in closed cavities and wound infections (patent RU 2003130945), which involves the use of an aqueous solution of chlorhexidine as an antiseptic solution, which is saturated with carbon dioxide, then fed into the wound, followed by simultaneous evacuation from the wound of the solution already with toxic products metabolism of the purulent-inflammatory process. The developed method prevents microbial dissemination in case of damage to the distal extremities, such as feet in diabetes. However, the method has a number of disadvantages. The time of the procedure is limited by the degassing time of the solution, which does not exceed a few minutes, which limits the time of treatment of the wound surface. There are difficulties in the treatment of superficial wounds that do not have a "cavity".

A known method of treatment of bitten wounds (patent RU 2597767), which allows the treatment of bitten wounds. The method includes placing a delimiting element over the wound to form a sealed cavity and jet washing the wound with water and detergent. Then the disinfectant liquid is poured into the wound through the inflow tube and at the same time the washing liquid is removed through the outflow tube to the outside. In this case, the delimiting element is placed with the formation of one cavity above all wounds, the wounds and skin are washed in the cavity with silver water with a concentration of silver ions in it of 21-25 mg/l. After washing the wounds, they are covered with a therapeutic and prophylactic external remedy and a napkin. The disadvantages of this method is limited use - only bitten wounds, the inability to clean the wounds from toxins and necrotic areas, a limited number of sanitizing factors per wound.

An analogue of the developed device is a software bubbling sanitation device (patent RU 100712) used for sanitation of purulent wounds, fistulas, as well as for isolated treatment of body parts with bubbling solution. The device for bubbling sanitation ensures bubbling of the medicinal solution throughout the procedure. It is equipped with regulators for changing bubbling modes, namely, a rheostat and a regulator of the internal section of the hose, and is equipped with a reliable fastener for fixing on the body surface. The economic feasibility of using the device is ensured by the use of atmospheric air passed through the filter as a working gas. The disadvantages of this device is the absence in the bubbling solution of surfactants that contribute to changing the environment on the wound surface, limiting the absorption of bacteria and toxic degradation products of tissue protein. Significant disadvantages are the lack of gas pressure control in the device, the absence of an abacterial filter, and the impossibility of changing gas sources.

EFFECT: debridement of wounds with a bubbled foam solution with precise pressure control and the possibility of switching gases in the system, as a result of which dense and viscous necrotic masses are separated, an unfavorable environment for the development of pathogenic microflora is created, the absorption of bacteria and toxic decay products is reduced, wound self-cleaning and development are accelerated. healthy granulations.

The device consists of an outer tank (1), an inner tank with a perforated bottom (2), a piping system with branches (4), a system of flexible hoses with splitters and perforated tips (7), an air compressor (6), an abacterial filter (5 ), sources of high pressure oxygen and carbon dioxide (8), a switch for supplying oxygen or carbon dioxide (9), a ball valve for adjusting the flow of gases (10), a pressure gauge for the pressure of the gas supplied to the system (11), a perforated container for a foam concentrate ( 12) (Fig. 1).

The device works as follows. Air is supplied by a compressor or one of the sources of high pressure gases. The compressor was used industrially, identical to the patented device (AQUAEL АР-100: operating voltage - 220 V, power - 2.5 W, maximum pressure up to 0.03 MPa), the compressor is also provided with a rheostat to change operating modes. Using a ball valve to adjust the flow of passing gases, the ratio of gases for treating the wound surface is set, for example, only air, only oxygen or only carbon dioxide, or in a ratio of 50/50, etc. (Fig. 2).

The outer container of the device (1) is a polymer container in the form of a "bowl" with a flat bottom and four square walls, on one of the walls there is a bracket for mounting the compressor (6) on the outer part of the wall. From the inside, an inner container (2) is placed in the outer container, which has slightly smaller outer dimensions, allowing it to be securely placed inside the main container so that between the bottom of the main container on the inside and the inner container on the outside there is a free space 10-15 mm high for the location of a system of flexible hoses with splitters and perforated tips (7). There are numerous holes in the bottom of the inner container over the entire surface. In the assembled state, in the free space at the bottom of the main tank, perforated tips (7) are located, connected in series by flexible hoses with a gas pressure gauge (11) and a ball valve for adjusting the flow of gases (10). Moreover, a hose with a switch for supplying oxygen or carbon dioxide (9) is connected to the latter from the distal side, respectively, connected to sources of high pressure of these gases (8). Before starting work, a perforated foam container (12) is placed on the bottom of the inner container.

Physiological solution is poured into the assembled device, and the foaming agent is placed in the foam container (12), so that the perforated bottom of the inner container is covered with a four-centimeter layer of liquid. Turning on the compressor, supplying air, or oxygen, or carbon dioxide, or gases in a certain ratio, leads to the filling of the flexible hose system with gas, which is blown through the fine holes of the perforated tips, providing foam bubbling-flotation debridement. This method allows sanitation of the wound surface without fixing the device to the body by immersing its part in a solution with a foaming agent.

After sanitation, the liquid and the foaming agent are removed from the device, the containers are separated from each other, the container for the foaming agent is removed, the system of flexible hoses with bubbling tips is removed, the outer container is disconnected from the compressor, sources of high gas pressure.

When disassembled, the device is easily subjected to pre-sterilization preparation and sterilization for reuse.
