SU1818103A1 - Device for treatment of contaminated wounds - Google Patents

Description

The invention relates to medicine, specifically to traumatology and orthopedics, as well as to surgery.

The purpose of the invention is to increase the effectiveness of treatment by providing drainage of the wound.

Figure 1 shows the balls in various sections; figure 2 - section A-A in figure 1; figure 3 - section B-B in figure 1; figure 4 - a fragment of interconnected balls with a pair of threads; figure 5 - balls interconnected by a perforated tube installed in the channels of the balls; figure 6 - the balls are interconnected by corrugated sections inserted hermetically between the channels of the balls.

The device is made of interconnected balls 1. Each ball 1 is made of bioinert, porous (for example, carbon-containing) polymeric material: semi-rigid or relatively easy to compress, depending on the specific purpose of the device. For example, semi-rigid balls 1 are used in the treatment of fistulous canals (passages) with rigid walls. Softer - compressible balls 1 are used in the treatment of soft tissue, easily vulnerable and bleeding wounds, especially those intimately adjacent to the neurovascular bundle, etc. i The diameter of the balls 1 varies, for example, from 2 to 10 mm, and the number of balls in each device varies over a wide range, J, for example, from 6 to 30 or more. ,

Each ball 1 is made with an axial, central channel 2, the walls of which contain holes 3. The holes 3 are connected coaxially with the holes 4 located on the surface of the ball 1 with the help of side channels 5 located at an angle relative to the channel 2. With the exception of the extreme balls in the chain, channel 2 of each ball 1 is coaxially, hermetically and sufficiently movably connected to a similar channel 2 of neighboring - adjacent balls 1, as shown in Fig.4 - 6. It should be noted that the central channel 2 and side channels 5, regardless of the structure of the material of the balls 1 , have in all cases sufficiently rigid and elastic walls to avoid overlapping of the lumen of these channels. Balls 1, as shown in the figures, can be connected in a chain (or otherwise, in beads) in different ways. It is only important that the device as a whole retain sufficient mobility and contain freely passable channels 2 and channels

5.

As shown in figure 4, the balls can be connected to each other by a pair of threads 6 with their complete reversible deformation. With this implementation of the device, the threads 6 are carried out in special through holes 7.

Balls 1 can be interconnected by a perforated polymer tube 8 installed in the channels 2 of the balls

1. In this version of the device, the balls 1 are, as it were, strung and fixed on the tube 8. In this case, the perforations of the tube 8 coaxially coincide with the holes 3 and holes 4, as shown in Fig.b.

In the device, the balls 1 can be connected to each other using flexible, including corrugated sections 9, as shown in Fig.b. The ends of sections 9 are hermetically fixed on balls 1 along the edges of the channel

2.

The material of the balls is impregnated (impregnated) through with antiseptics, for example, preparations of iodine, copper; silver; antibiotics, antioxidants and other medicinal and antimicrobial drugs. The inner surface of channel 2 and channels 5 is also treated with similar antiseptic agents. Two or more antimicrobial agents can be used in the same device to potentiate the antimicrobial action and achieve a synergistic therapeutic effect. Other well-known methods can be used to apply medicinal preparations to the balls 1 - electrochemical: chemical and physical (for example, Trimer, vacuum deposition, etc.).

The proposed device is used as follows.

Carry out the toilet of the wound channel, or its surgical treatment. Next, a suitable device is selected taking into account the size of the balls 1, their rigidity, the length of the entire chain of the device, as well as the type and combination of antimicrobial agents with which the balls 1 are treated (the microflora of the wound is determined in advance and its sensitivity to the antimicrobial agents contained in the balls 1 is checked). If the device is used for local treatment of a postoperative wound, then proceed as follows. A chain of balls 1 of the required length is placed in the wound cavity, and one end of it is brought out through a separate hole. The wound itself is sutured tightly and a sterile bandage is applied to it. In the postoperative period, during dressings, the end of the shaft 2 brought out to the outside is evacuated from the wound discharge and the rind (fistula) canal is washed. As the wound heals, the device is gradually removed from it. The device can also be used for irrigation-suction wound drainage. In cases where the device is used in the preoperative period or in the conservative treatment of the fistulous canal: cavity, then after an appropriate toilet, the wound is inserted and the device is installed in it using a special guiding probe through the fistulous opening, and its free end is fixed on the skin, for example , adhesive plaster. During dressings, the wound cavity is also washed through channel 2. In some cases, it is possible to remove the proposed device from the wound channel (or cavity) and replace it with another one, for example, with a different set of antimicrobial agents; with a different number and sizes of balls 1,

The described device reduces injury due to the implementation of the balls 1 of a semi-rigid and fairly soft material. The pores of the balls 1, on the one hand, allow for local drainage due to the capillary ability of the material of the balls, and on the other hand, increase their active antimicrobial surface by two or more orders of magnitude. To do this, the surface of the balls 1 is made rough, bumpy; in the form of a boucle, etc. In addition to antimicrobial agents, balls 1 can be treated with other therapeutic agents, including wound healing agents. On the surface of the balls 1, galvanic couples can be created from metals with medicinal properties, for example, from microelements.

The proposed device has a simple structure, available for use in any medical institution; effective, since it creates a depot of antimicrobial agents in the wound and at the same time allows drainage in it with the possibility of introducing the necessary therapeutic solutions into the wound.
