Injector systems including a syringe for use with a powered injector having a drive membre to inject a fluid into a patient having a first indicator positioned on the syringe at a predetermined position are described. The position of the first indicator may be associated with information about the syringe configuration. The first indicator can, for example, be positioned on a rear surface of an attachment flange of the syringe. The injector system includes sensors each having on and off states, and a shutter mechanism configured to place sensors in the on or off states. The state of each of the sensors provides a digital code corresponding to information on the syringe configuration.

Injector system for encoding and sensing of syringe information

An adapter for releasably attaching a syringe to an injector includes a first section and a second section connected about a hinge axis that is generally perpendicular to a longitudinal axis of the adapter. The first section and the second section are rotatable about the hinge axis between an open position to allow loading of the syringe into the adapter from a position to the rear of the hinge axis and a closed position to retain the syringe therein. The hinge axis is preferably off-center from the longitudinal axis of the adapter and the adapter further includes a releasable mounting mechanism positioned on a rearward end of the adapter to mount the adapter in a desired position relative to the front wall of the injector.

Syringe adapters for use with an injector

Medical injector

The present invention provides pressure measuring devices comprising a sensor to detect the force upon at least a portion of a contact surface of a syringe plunger during pressurization of a fluid medium within the syringe. A determination of the pressure of the fluid medium within the syringe is thereby enabled.
