RAYON-BASED CARBON DRESSING Russian patent published in 2013 - IPC A61L15/16 A61L15/28 B82B3/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to surgery, burn and radiation therapy. A dressing contains rayon fabric which at the first stage of carbon cloth production is exposed to ionising radiation of a high-speed electron bunch in cathode-ray current (1-3) mca and power (0.5-0.7) MeV when transported through an electron accelerator exposure chamber at rate (1-4) m/min; the produced carbon cloth is characterised by density 1.3-1.4 g/cm³; surface density 2.5-3.5 m²/g; carbon content 99.6-99.9 wt %; ash content 0.1-0.4 wt %; chlorhexidine absorption 0.6-0.7 g/g if continuously coating the wound surface for 4 days.

EFFECT: dressing is characterised by high sorption dynamics, does not stick to the damaged skin, and does not scar after burns, cleans the wound surface so that reduces a time for wound preparation for closure in 1,5-2 times due to its high mechanical strength and chemical resistance of the carbon cloth after graphitisation at 2400°C; the dressings are re-useable.
