INJECTION DEVICE WITH MEANS OF ELECTRONIC CONTROL Russian patent published in 2013 - IPC A61M5/172 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical injection device for application with cartridge. Device contains spring-loaded means, configured for storing energy during procedure, which precedes injection, drive element, made with possibility of moving piston of said cartridge towards exhaust end of cartridge, with application to drive element during injection of effort, created by spring-loaded means when energy, stored in said device is released; component for initiation of release of energy by spring-loaded means, thus starting introduction of dose. Sensor is made with possibility of detecting positional information, which relates to drive element or component, connected to drive element. Electronic circuit is connected with sensor, intended for processing signals, which are formed by sensor and is made with possibility of determining data about speed of dose introduction on the basis of signals, formed by sensor, compare data about said speed with earlier determined data about speed and realise controlling influence, when speed of dose introduction, determined during injection, goes beyond the range of normal values. Structurally different version of device is described.

EFFECT: reducing risk of inaccurate dose.
