SYSTEMS AND METHODS FOR ANESTHETISING OF EAR TISSUES Russian patent published in 2014 - IPC A61M19/00 A61N1/30 A61F11/08 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine, namely otorhinolaryngology and may be used for various ear diseases. That is ensured by presenting the systems for electrophoresis drug delivery to a human or animal ear drum. The system contains an ear tampon having distal and proximal portions with a tube passing in between and having a smaller rigidity as compared to the proximal and distal portions of the ear tampon. One flexible sealing element extending from an external surface of the tube and closer to a distal end than to a proximal one. An electrode consisting of an extended shaft, a tip having a greater diameter as compared to the trunk. The electrode is placed inside of the tube of the ear tampon from the retracted position wherein a fluid can flow in the tube round the electrode into the extended position, wherein the electrode tip is in contact with the internal surface of the tube thereby preventing the fluid flow in the tube. The system can also comprise two flexible sealing members integrated with the extended tube. There are also presented methods for anaesthetising the ear drum by using the given system. There are presented kit for anaesthetising comprising the drug delivery system and controller coupled with the electrode.

EFFECT: inventions provide the drug delivery, including anaesthetics into the patients being in the vertical position, due to a possibility to retain the solution hermetically in the external ear canal with no additional conditions provided.
