SIMULATOR FOR AUTOMATIC INJECTIONS Russian patent published in 2017 - IPC G09B23/28 

FIELD: medicine.

SUBSTANCE: simulator comprises a housing assembly with an outer housing, a trigger assembly and a damper unit inserted into the outer housing. The damper unit comprises a damper housing and a piston assembly located in the said damper housing. The damper housing is mounted with a possibility of movement relative to the piston assembly and/or the outer housing to the proximal end of the device from a charged position to a position after the injection simulation, due to the outward axial force from the first energy storage element. The piston assembly is arranged to provide the first resistance to the flow of fluid therethrough in a proximal direction, and to provide the second resistance to the flow of fluid therethrough in a distal direction, wherein the second resistance is less than the first resistance. The unit for simulator recharging is disclosed.

EFFECT: provision of repeated simulator application for automatic injection testing.
