A hand-held remote for a medical fluid injector includes a syringe and a conduit which may be coupled to a pressure transducer on a control circuit of the injector. Movement of a plunger within a syringe body on the syringe creates a pressure which is sensed by the pressure transducer and the control circuit responds to the sensed pressure by causing fluid to be ejected from, or drawn into, a syringe mounted to the injector. The pressure developed by the remote provides tactile feedback to an operator for improved control over injections.

Hydraulic remote for a medical fluid injector

The present invention is directed to control of medical fluid injection systems. For instance, in some embodiments, an injection protocol may be initiated, and an actual flow rate of the medical fluid utilized in the injection protocol may be adjusted based, at least in part, on an inherent system elasticity of the injection system.

Methods for controlling medical fluid injections

A remotely powered magnetic resonance (NR) contrast media injector eliminates the use of batteries to power a power head in a shielded magnet room thereby eliminating inconvenient and costly charging and replacing of batteries. In particular, a power supply regulates and converts electrical power from a standard utility AC outlet available outside of the shielded magnet room to one or more forms of electrical power for supplying a power control for a power head inside the shielded magnet room. Advantageously, the power supply increases flexibility and convenience by using the same number of electrical cables as existing systems and by readily retrofitting existing battery-powered injector system that use a power control with battery receptacles.

Remotely powered injector

A medical fluid injector includes: an air detection system for detecting air in the neck of the syringe; a hand-operated control lever for controlling movement of the injector ram; magnetic conductors for delivering magnetic fields from a power head face plate to an internal circuit board to permit detection of different face plates; a tilt sensor detecting the tilt angle of the power head to control the speed of motion brought about by the hand-operated control lever and to control an invertible display; and a monitor microcontroller for monitoring the behavior of the central processing unit to detect and react to error conditions.

Medical fluid injector

A syringe discharge end having a rotatable tubular connector member for engaging a luer connector on medical tubing. The syringe discharge end and the connector have mating threads which are used to affix the connector to the syringe discharge end. Once affixed, the connector is may freely rotate relative to the syringe, while being prevented from axial movement. On its distal end, the connector includes internal threads for engaging external threads on a standard luer connector of medical tubing. To engage the connector to tubing, the connector is rotated relative to the tubing and the syringe to draw the tubing onto the syringe discharge end.
