DRUG DELIVERY DEVICE CONTAINING LOCK MECHANISM Russian patent published in 2017 - IPC A61M5/20 

Abstract RU 2621536 C2

FIELD: medicine.

SUBSTANCE: invention contains a tubular chassis (11) with the proximal end, the distal end. The drive (60) is made with a possibility of forceapplication to the drug tank (70) for drug withdrawal. The drive holder is made with a possibility of retaining with the release of the drive in a pre-tense state prior to drug delivery. The holder (50) contains a long tubular part (52) for drive reception enabling its axial movement therein. The release ring (54) is located coaxially on the long tubular part. The release ring is made with a possibility of axial displacement along the outer surface of the long tubular part. The long tubular part is made with the ability to engage with the drive when the release ring is in the proximal position, and release the drive when the release is ring moved in the distal direction away from the proximal position. The release ring includes a pair of locking levers (55) in the proximal direction. A pair of locking levers is made with an ability to engage with the corresponding groove (58), formed on the outer surface of the long tubular part when the release ring is in the proximal position.

EFFECT: safe storage and disposal, increased economic efficiency and operation stability.
