Abstract
A medical fluid injector device capable of injecting a patient with a mixed medical fluid and simply setting injection conditions for the mixed medical fluid. A medical fluid injector includes an injector head injecting a diluted contrast medium into a patient and a controller unit. The controller unit receives an input relating to an injection rate of the diluted medical fluid, receives an input relating to a mixture ratio by an operator, calculates an injection rate of a contrast medium based on the mixture ratio, and calculates an injection rate of physiological saline based on the mixture ratio. The injector head injects the contrast medium and the physiological saline at the calculated injection rate of the contrast medium and the calculated injection rate of the physiological saline, respectively.
Claims8
A medical fluid injector device, comprising:
- an injector head configured to hold a first syringe filled with a first contrast medium and a second syringe filled with saline or a second contrast medium and inject diluted contrast medium, wherein said diluted contrast medium is delivered via a catheter for angiography;
- a controller unit operably connected to the injector head, and
- a hand controller;
- wherein the injection head is configured to:
- inject a diluted contrast medium at a given mixture ratio or mixture factor, and
- change an injection rate of the diluted contrast medium when an operator manipulate the hand controller, with the mixture ratio or mixture factor unchanged.
