INJECTION DEVICE Russian patent published in 2018 - IPC A61M5/24 A61M5/315 

FIELD: medicine.

SUBSTANCE: invention relates to medicine. Injection device with the adjusting member that is configured in order to adjust the amount of injected liquid, which is squeezed out of the injection device, and has the possibility of its rotation relative to the body of the injection device about the central longitudinal axis of the injection device in the first direction of its rotation and with the possibility, when squeezing the injected liquid from the injection device, of its rotation in the second direction of rotation opposite to the first direction of its rotation. Adjusting member is connected to the housing by means of the first threaded connection and has the possibility of its rotation in the distal direction when adjusting the squeezed amount of the injected liquid in addition to the rotation in the first direction of rotation and with the possibility of moving in the proximal direction when extruding the predetermined amount of the injected liquid in addition to the rotation in the second rotation direction, and with the locking device that detects at least one fixing position of the adjusting member. Locking device operates between the adjusting element and the body, the locking device being operative at least when adjusting the amount of the injected liquid, which is squeezed out from the injection device. Each fixing position corresponds to the unique rotation position of the adjusting element with respect to the body.

EFFECT: invention provides for several locking positions that are located at different distances.
