DEVICE FOR SETTING MICRO-NEEDLES Russian patent published in 2004 - IPC

FIELD: medical engineering.

SUBSTANCE: device has two casing parts. The casing parts are in perpendicular relation to each other. Mechanism for setting micro-needles is mounted in one of the parts and mechanism for feeding micro-needles is mounted in the other one. The casing parts are joined with canal for transferring micro-needles to mechanism for setting them. Spring-loaded rod as feeding plate having supporting button is mounted in this part on one side, and lateral outlet member having opening which passage cross-section area is equal to micro-needle cross-section area calculated from fixing ring diameter. Mechanism for feeding micro-needles is enclosed in hollow cylindrical casing having longitudinal canal for guiding micro-needle tip. It has cover with at least two members for guiding micro-needles fixed on its internal side. Opening is available in the central part of cover body having two spring-loaded fixing members mounted on its opposite internal sides. Spring-loaded feeding rod is mounted in the opening allowing its translation motion to take place. One end is connected to supporting washer. Fixing button is mounted on the other end. Ring-shaped notch is available on the rod body.
