INJECTION DEVICE PROVIDING MINIMUM INVASIVENESS Russian patent published in 2018 - IPC A61M37/00 

FIELD: medicine.

SUBSTANCE: device comprises a nozzle assembly that includes the first reservoir for the liquid to be injected, an output component to generate the liquid microjet, and a micro-size injection unit connected to the output component and adapted to be inserted into the skin tissue at a predetermined depth and a portion providing pressure and comprising the first pressure application unit, the third pressure application unit connected to the first pressure application unit and configured to apply pressure to the first reservoir and the first pressure generator, which provides pressure to the first pressure application unit. At that, in the third pressure application unit, a ring or a locking protrusion is formed, and in the first pressure application unit, a groove adapted to mate with the ring, or a groove adapted to mate with the locking protrusion is formed in the corresponding extension length. Moreover, several output components and associated injection units are connected to the first reservoir, and several protrusions are made in the third pressure application unit, consistent with the design of the output components.

EFFECT: minimal invasiveness.
