ADAPTER FOR DRUG DELIVERY DEVICE AND DRUG DELIVERY DEVICE Russian patent published in 2020 - IPC A61M5/34 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, specifically to adapter (130, 230, 330, 430, 530, 630) for drug delivery device (10) and drug delivery device (10). Adapter has reservoir (12) and longitudinal tip (20). Longitudinal tip (20) has outer surface (20a) and longitudinal channel (21) for dispensing any material stored in reservoir (12). Adapter (130, 230, 330, 430, 530, 630) comprises distal portion (130a, 230a, 330a, 430a, 530a, 630a) defining connection ring (131) for receiving connector, and proximal portion (130b, 230b, 330b, 430b, 530b, 630b) defining setting ring (133, 233, 433, 533, 633) having inner surface (134, 234, 334, 434, 534, 634). Mounting ring (133, 233, 433, 533, 633) has such shape and configuration that, when adapter (130, 230, 330, 430, 530, 630) is installed around longitudinal tip (20) of drug delivery device (10), between inner surface (134, 234, 334, 434, 534, 634) of locating ring (133, 233, 433, 533, 633) and outer surface (20a) of longitudinal tip (20) annular gap (138) is made, made with possibility arrangement there is adhesive layer (40) for connecting said adapter (130, 230, 330, 430, 530, 630) to said longitudinal tip (20). Distal projection (136, 236, 336, 436, 536, 636) is made on the distal end of inner surface (134, 234, 334, 434, 534, 634) of the locating ring. Device (10) for drug delivery comprises adapter (130, 230, 330, 430, 530, 630).

EFFECT: technical result is not only optimal pull-out force, but also resistance to torque and possibility of installation on common longitudinal tip.
