METHOD FOR APPLYING COATING TO MEDICAL DEVICE COMING INTO CONTACT WITH BODY TISSUES Russian patent published in 2021 - IPC C23C14/04 C23C14/06 C23C14/14 C23C14/30 A61L31/08 A61L31/14 

FIELD: medical equipment.

SUBSTANCE: invention relates to medical equipment, namely to an injection needle coming into contact with body tissues. The injection needle includes coating obtained by purification and activation of a needle surface by accelerated ions and further ion-plasma spraying first with a flow of gaseous accelerated particles containing a silicon-organic compound, and further ion-plasma spraying with a flow of gaseous accelerated particles containing metal atoms: iron (Fe) and/or titanium (Ti).

EFFECT: obtaining coating on the injection needle, which allows for measuring electric parameters of biological environment (electrical impedance) in in the area of the piercing part of the needle, while injecting the needle to biological tissues, while the measurement result does not depend on the injection speed, which allows for high accuracy of control of the needle position in real time.
