Abstract

The invention relates to medicine, namely to surgery for the prevention of suppuration of wounds. The essence of the invention lies in the fact that the perforations of the drainage tube are made in the form of longitudinal slots located along a helical line along the tube. 3 ill.

Description

The invention relates to medicine, namely to surgery, and can be used to prevent suppuration of wounds.

i A device for treating purulent wounds is known, comprising a drainage tube with perforations connected at one end to an aeration source and the other to a container.

i A disadvantage of the known device is the inability to prevent the development of infection after drainage.

: The purpose of the invention is to eliminate the disadvantages indicated.

To achieve this perforation, the wood tubes are made in the form of longitudinal; the slots located along the screw along the tube, while the capacity is made of elastic material.

During the supply of oxygen and higher: the pressure in the tube and vessel is linear: the incisions expand, while the wound is irrigated with oxygen. The supply of oxygen ceases when the elastic viscosity expands to a certain size. Further irrigation of the wound is achieved due to the elasticity of the container. After the consumption of oxygen, the pressure in the tubes and capacity is reduced to a minimum, while the incisions stick together, thereby eliminating the conditions for

accumulation of wound exudate in the lumen of the tube.

Figure 1 shows a drainage tube; figure 2 and 3 - the described device.

The device comprises a drainage tube T with perforations in the form of longitudinal slots 2 located along helical lines connected to an aeration source 3 with a capacity of 4 made of elastic material.

The device is used as follows.

When wounds are sutured, tubes 1 are laid on its layers, the ends of which are brought out onto the skin surface. The ends of the tubes on one side are connected through a tee to a container 4, the opposite ends are connected to an oxygen source 3 during an oxygen therapy session of a postoperative wound. In the postoperative period, oxygen is supplied from the source 3 at a low pressure, and after a certain time, the capacity 4 is filled to a certain volume. The oxygen supply is shut off. Further oxygen therapy of the wound layers occurs due to the force of elasticity of the container. At first, due to the high tissue demand for oxygen, the capacity is filled 2-3 times per session. In the first two days, oxygenation of the wound produced C

it is administered twice a day, hereinafter once a day. The tubes are removed after 3-4 days.

If necessary, drainage of the wound layers of the tube 1 can be used as drainage. For this, the ends of the tubes which are connected to the elastic container are plugged, and the opposite ends are connected to a vacuum source. A vacuum of 0.05-0.1 atm is created. In this case, the slots 2 on the tubes open slightly into the lumen of the tubes. Thus, active drainage of wounds occurs.

Form of the invention A device for treating purulent wounds, comprising a drainage tube with perforations connected at one end to an aeration source and the other to a container, characterized in that for the purpose of warning: 2. JL

To prevent the development of infection after drainage, perforation of the drainage tube is made in the form of longitudinal slots located along a helical line along the tube, and the container is made of elastic material.
