Device for carrying out sorption streaming debridement

摘要

The device relates to medical technology, namely to devices for local treatment of wounds. Designed for targeted application of powdered substances with a stream of compressed oxygen or carbon dioxide to the wound surface. The device consists of a body, a nozzle for directing the flow of the outgoing jet, containers for drugs, two sources of high gas pressure, pressure and gas flow regulators. A distinctive feature is the presence of two containers for applying powdered drugs to the wound surface, the presence of two sources of high gas pressure - oxygen and carbon dioxide, the location of the nozzle for directing the flow of the outgoing jet at an angle of 30 °, the presence of a cascade of mixing chambers. pressure of oxygen and carbon dioxide, provides mixing of medicinal substances due to the Venturi effect, promotes uniform distribution of two powdered medicinal substances on the wound surface. The location of the nozzle for directing the flow of the outgoing jet at an angle of 30 ° provides an economical and accurate application of drugs, the ability to treat "wound pockets". The presence of simultaneously sources of oxygen and carbon dioxide provides an effect on both aerobic and anaerobic flora.
