AUTOMATIC DRUG DELIVERY DEVICE Russian patent published in 2022 - IPC A61M5/20 

FIELD: medical equipment.

SUBSTANCE: present invention relates to medical equipment, namely to automatic drug delivery device (10), in particular to an automatic drug delivery device intended for dosing of a fluid product, in particular a fluid drug. The device contains longitudinal case (104) extending along a longitudinal axis and having a proximal end near a dosing site, a distal end opposite to the proximal end, and a hollow inner part; removable lid (50) made with the possibility of installation on the proximal end of case (104); node (200) in the form of a syringe, located in an installation position inside case (104) and having hollow main part (204) of the syringe and injection needle (206) connected to hollow main part (204) of the syringe, containing the fluid product; drive mechanism (300), which can be actuated by a starting element to start dosing of the fluid product. At the same time, the loaded drive mechanism is functionally connected to protective casing (102) made with the possibility of movement inside longitudinal case (104). Moreover, protective casing (102) is shifted to a proximal position, in which it protrudes outward from the proximal end of longitudinal case (104) to close tip (348) of a needle, which is injection needle (206), while protective casing (104) is made with the possibility of movement to a distal position, in which injection needle (206) is opened for an injection. At the same time, the removable lid, in an axial direction, is retained at the proximal end of the longitudinal case due to engagement of retaining elements between the lid and the longitudinal case, wherein retaining elements disengage by rotation of the lid relatively to the longitudinal case to provide the axial movement of the lid relatively to the case to remove the specified lid, wherein the axial movement of the lid relatively to the case is supported by a shifting force applied to the protective casing.

EFFECT: obtaining an automatic drug device.
