MEDICAL DELIVERY DEVICE Russian patent published in 2015 - IPC A61M5/315 

FIELD: medicine.

SUBSTANCE: injection device contains case and container holder, placed in case, drive unit and indication mechanism. Container holder is made with possibility of placing container with medical substance, which has needle, fixed on one of its ends, and plug, placed with possibility of creating compression and sliding inside container with medical substance on its other end. Drive unit contains plunger rod and means for plunger control. Means for plunger control is made with possibility of sliding relative to plunger rod, is rotationally blocked on plunger rod and has possibility of revolution relative to case. Mentioned drive unit additionally contains first unit for energy accumulation, placed in internal space of case of injection device and made with possibility of accumulation and storage of energy. Device for plunger control is functionally connected with said first unit for energy accumulation. Device for plunger control is made with possibility of unlocking in such way that due to output torque from first unit for energy accumulation device for plunger control can be brought into rotation. Plunger rod is forced to move in direction of proximal end of injection device, which results in performing injection. Mechanism of injection indication is made with possibility of indicating course of injection performance to user. Mechanism of injection indication contains tactile signal unit and drive mechanism for control of tactile signal unit, with drive mechanism being connected with device for plunger control on distal end of plunger control device, and injection indication mechanism is placed in such a way that user senses the course of injection realisation.

EFFECT: application of invention makes it possible to track realisation of slowly performed injections.
