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 node in the form of a syringe is equipped with a casing for the needle, attached to the proximal end of the hollow main part of the syringe, and closing the needle together with its pointed tip. Moreover, the removable lid contains a flexible element for capturing, intended for engagement of the casing for the needle for its outer circular surface, so that removal of the removable lid leads to the removal of the casing for the needle, wherein the flexible element for capturing has a greater diameter than the proximal end of the protective casing.

EFFECT: obtaining an automatic drug device.
