SOFT TISSUE INJECTION METHOD Russian patent published in 2008 - IPC A61M5/178 A61B8/00 A61K31/245 A61P23/02 A61M5/158 

FIELD: medicine.

SUBSTANCE: initially skin area is chosen for anaesthesia. Then ultrasonic sensor is applied, and various skin areas are periodically pressed by finger, thus observing wavy changes of tissue structure under pressing on the screen. Place chosen for injection is that where deformation wave most precisely reaches chosen area. Further distance to chosen area from skin surface is measured with following tissue puncture with long injection needle on this depth with preliminary introduction of novocaine in amount 1-1.5 ml. Localization of medicinal infiltrate appearing in tissues is visualised, and if infiltrate created by novocaine injection is resolves within no more than 1.5 minutes, this area is intermittently introduced with medicinal agent dosed 1 ml under ultrasonic control of every introduction accuracy and infiltrate resolution intensity. Next portion of medicine is introduced after complete infiltrate resolution, created by last portion. In case infiltrate is intact within 3 minutes medical product introduction is stopped, and in medicinal infiltrate is introduced with 10 ml of novocaine solution.

EFFECT: prevention of postinjective complications owing to area selection accuracy.
