INJECTION DEVICE Russian patent published in 2019 - IPC A61M5/20 

FIELD: machine building.

SUBSTANCE: injection device for automatically squeezing a dose of an injection liquid from a container, comprising body (2, 102) with a longitudinal central axis (50, 150), metering piston (11, 111) and control portion (16, 116) of the injection device, wherein metering piston (11, 111) and adjusting part (16, 116) of injection device are configured to - when squeezing injection fluid - displacement relative to each other, and injection spring (9, 109), wherein when squeezing injection liquid from container (5, 105) is provided possibility of at least partial release of energy stored in injection spring (9, 109), leading to extrusion of dose of injection liquid from container (5, 105), wherein injection device (1, 101) comprises control device (41, 141) for adjusting the injection rate, which is provided with the possibility of squeezing the injection liquid from container (5, 105), having the possibility of affecting energy, required for movement of adjusting part (16, 116) of injection device relative to metering piston (11, 111), characterized in that dispensing piston (11, 111) and adjusting part (16, 116) of the injection device are configured to - when squeezing the injection liquid - moving relative to each other in the longitudinal central axis (50, 150) direction, wherein adjustment device (41, 141) is configured to - when adjusting the injection rate - action on position of rotation of dispensing piston (11, 111) relative to control part (16, 116) of injection device.

EFFECT: disclosed is an injection device.
