INJECTION PEN SYRINGE TYPE DEVICE AND ELECTRONIC ATTACHMENT MODULE FOR THIS DEVICE Russian patent published in 2017 - IPC A61M5/24 

FIELD: medicine.

SUBSTANCE: auxiliary device contains: main part with a front end and a rear end; and a connecting node configured with an ability of detached installation of the main part on the injection device in a specific position relative to the outer surface of the injection device. At that, the connecting node contains a sleeve, continued from the front end of the main part at an acute angle to the longitudinal axis of the main part that is configured to host the injection device so that the injection device continues through the sleeve and the sleeve has a hole; an engaging node configured to engage the auxiliary device with the injection device; and the first and second installation surfaces located apart from each other to accommodate the injection device between them, at that, the first and the second installation surfaces are shifted. The sleeve is configured to rotate about the axis extending perpendicularly to the major axis of the hole between the first position in which the injection device can be disposed by shearing through the sleeve, and the fixed position in which the first and second mounting surfaces are located closely to the external surface of the injection device and are positioned so that no part of the first mounting surface is directly in front of the second mounting surface when it is in the fixed position. At that, the engaging unit is adapted to engage with the injection device when the sleeve is rotated to the fixed position.

EFFECT: improvement of the device.
