WOUND TREATMENT SYSTEM AND METHOD WITH USING ULTRASONIC SURGICAL PURIFICATION Russian patent published in 2011 - IPC A61M1/00 A61M27/00 A61F13/00 A61M35/00 A61N7/00 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine, namely to wound treatment methods and apparatuses by means of combination of ultrasonic wound purification and low pressure therapy. The wound treatment system comprises a supply manifold, a low pressure source, a liquid source, an ultrasonic transducer and an adjoining protective film for closing of the supply manifold and the ultrasonic transducer. The second version of the treatment system additionally involves a sound-conducting membrane adjoining the manifold. The wound treatment method provides using the system with the supply manifold accommodating a number of flow passages and adjoining a wound area. For the first version, supplied ultrasonic energy power is 1 Wt/cm² for 10 minutes a day. For the second version, liquid from the liquid source is supplied to the wound during first time, while ultrasonic energy is supplied during second time, and low pressure - during third time. For the third version, low pressure and ultrasonic energy are supplied to the wound simultaneously, and low pressure is maintained by means of the protective film placed over the supply manifold. For the fourth version, liquid is preliminary supplied in the wound, then ultrasonic energy; then liquid and separated tissue are removed by low pressure. The wound treatment system can be presented in the form of a wound bandage.

EFFECT: use of the group of inventions allows providing higher clinical effectiveness.
