IMPROVED DEVICE FOR DOSAGE ADJUSTMENT WITH RESTRICTIVE MECHANISM FOR PRODUCT DELIVERY DEVICE Russian patent published in 2017 - IPC A61M5/315 

FIELD: medicine.

SUBSTANCE: device comprises the first and the second limiting means with the first and the second locking means, respectively. Moreover, the second restricting means follows the movements of the first restricting means during metering movement with a predetermined gear ratio. Moreover, the second restricting means does not move relative to the first restricting means during the delivery process. Each of the first and second locking means follows a curvilinear trajectory as it moves so that the two curvilinear paths intersect at least in one point or run close to each other, so that the stop means contact each other in the locking position, at that, blocking of restrictive means movement relative to each other during the dosing process. At that, the respective curvilinear trajectories drawn by the first and the second locking means are closed and can be traversed, preferably several times, by the first locking means, the second locking means, or both, until the locking means contact each other in the locking position.

EFFECT: improvement of the device.
