<p>Disclosed is a medical liquid injecting device capable of injecting an injection pattern of a contrast medium optimum for the photography of a fluoroscopic image of a heart. The injecting device (100) is provided with a piston drive mechanism (130), which has a contrast medium syringe (200C) and a diluent syringe (200P) mounted thereon for causing the two syringes (200C, 200P) to act independently. The injecting device (100) comprises protocol setting means (410) for setting the injection protocols of the contrast medium and the diluent, and rate control means (440) for controlling the action of the piston drive mechanism (130) in accordance with the injection protocols. In the injecting device (100), the protocol setting means (410) receives such settings of the injection protocols that the injection rate (VA) of the contrast medium is higher than the injection rate (VB) of the diluent when a time (T1) elapses after the injection start, that the injection rate (VA) of the contrast medium monotonously decreases whereas the injection rate (VB) of the diluent monotonously increases for the period from the time (T1) to a time (T2), and that the injection rate (VB) of the diluent is higher than the injection rage (VA) of the contrast medium when the time (T2) elapses.</p> |
