INJECTION DEVICE Russian patent published in 2013 - IPC A61M5/20 A61M5/24 A61M5/31 A61M5/32 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to injection devices, particularly, but nor exclusively, to reusable autoinjectors. The injection comprises a syringe built in a body, a driving element and a magnetic indicator for injection completion indication. The driving element is movable from the first to second position to displace a dose from the syringe. The magnetic indicator comprises two interfacing elements one of which is coupled with the driving element, and another one - with the body. One of the interfacing elements represents a fixed element, while another one is a magnetic element movable on the coupled driving element or the body. Two interfacing elements are arranged so that if the driving element is found in the second position, or nearby, the above movable magnetic element moves into the indication position under the action of magnetic forces, thereby leading to a collision generating an audible injection completion indication and/or a tactile injection completion indication.

EFFECT: invention enables making the injection completion signals to the user when the injection device is found out of a vision field.
