Description

The invention relates to medicine, in particular to a blowing and aspiration apparatus used to clean wounds.

The purpose of the invention is improving the quality of the wound.

The drawing shows a device, General view.

A device for draining purulent cavities contains an elastic drainage tube 1 with a central channel connected to a container 2 for medicinal fluid, a device 3 for pumping air connected to an elastomeric sealed balloon 4 using a tube 5. The drainage tube 1 is made of: from the front 6, middle 7 and output 8 parts. The middle part 7 is made non-perforated from a softer elastic material than the rest of the parts, and is placed in an elastic sealed container 4. The latter 2 is coated externally with an antiseptic. The drainage tube 1 is connected to the container 2 for the medicinal fluid through the tube 9. On the side surface of the front 6 and the outlet 8 of the drainage 2 of the tube 1, perforations 10 are made.

The device is used as follows.

The drainage tube 1 and the elastomeric 3 sealed balloon 4 are placed in the wound. Medicinal fluid from the tank 2 through the tube 9 and the front part 6 of the drainage tube 1 through the holes 10 is fed into the wound.

By manipulating the device 3 for pumping air 3, air is supplied through the tube 5 to the sealed balloon 4 and inflated.

The cylinder 4 is externally coated with an adhesive composition with antiseptic crystals. There is a mechanical treatment of the walls of the purulent cavity by periodically inflating the balloon 4. Separated from the walls of the contents flows into the lower part of the wound and through the outlet part 8 of the drainage tube 1 is removed to the outside.

The removal of wound contents is facilitated by the periodic inflating of the balloon 4, which displaces the wound contents, and the compression of the middle part 7 of the drainage tube 1, which is placed in the balloon 4 and works on the principle of a pipette.

The use of a device for draining purulent cavities allows us to provide continuous mechanical treatment of the purulent cavity, to improve the quality of the wound treatment and to accelerate the healing process.
