Abstract
The invention relates to injection apparatus that is capable of operating continuously. According to the invention, the apparatus comprises two independent injection bottles (12) of at least one liquid that is to be injected into a patient via a tube, each of the bottles including means (51) for detecting that injection of the liquid contained in the bottle has terminated, which means control means (53) for interrupting the flow of liquid. The apparatus comprises upstream injection apparatus (10) having two feeder tubes (50) connected to respective bottles (12), and downstream injection apparatus (70) with pump means (72, 84) for pumping the liquid and connected firstly to the patient via a downstream tube (78) and secondly to coupling means (54).
