MEDICAL INJECTOR WITH FRONT LOADING AND SYRINGES TO BE APPLIED WITH IT Russian patent published in 2010 - IPC A61M5/00 A61M5/145 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to medical injectors with front loading and syringes, syringe interfaces, syringe plungers and adaptors for application with novel or existing medical injectors, in which syringe of special construction is made with possibility to be installed into injector and to be released from injector by means of split mechanism. Syringe for application with injector connects syringe-holding mechanism, which contains flexible ring. Syringe contains case, plunger, movably placed in case; at least one fastening element, connected with case. At least one fastening element interacts with flexible ring of syringe-holding mechanism for split fixation of syringe to injector. At least one releasing element is made with possibility to deform flexible ring in order to ensure syringe release from fastener to injector when syringe rotates around its axis with respect to injector. At least one releasing element is located in axial direction before at least one fastening element. Injector for injecting liquid from installed on it syringe contains case, drive element at least partly located in case and made with possibility of engagement with plunger, located inside syringe, and syringe-holding mechanism. Syringe-holding mechanism is connected with case and is made with possibility to intake syringe when it is moving axially backward with respect to syringe-holding mechanism irrespective of orientation of syringe around its axis. Syringe-holding mechanism in fact consists of flexible ring, held in fixed axial position in syringe-holding mechanism. In second version of injector implementation drive element contains flexible ring, located on it for engagement with plunger, located inside syringe. Flexible ring in first state is adapted for engagement with plunger and formation of connection with it, when plunger is turned around its axis into first position. Flexible ring, deformed to second state, is adapted for plunger release, when plunger is turned around its axis into second position. Syringe for application with injector, which contains syringe-holding mechanism. Syringe contains case, plunger, movably placed in case, and at least one fastening element, connected with case. At least one fastening element contains flexible ring, made with possibility of split fixation of syringe to injector.

EFFECT: invention allows to connect syringe with injector easily without taking into account specific orientation of syringe and/or syringe plunger.
