FIELD: medicine.
SUBSTANCE: one version of device contains tube of main supply with two clearances; main, which has multiple flow canals, located inside the first hole of main supply tube; and air balloon, which has internal space and is made with possibility to take compressed and extended state, internal space being connected by flow with the second clearance of main supply tube. Versions of device differ by application of non-permeable membrane. Membrane has internal space and is made with possibility to take extended or compressed state. In order to reduce volume, taken by main, lower pressure in internal space of non-permeable membrane is lower than pressure outside non-permeable membrane.
EFFECT: excluding of live tissue growing into material cells and providing access to deep wounds.
