Abstract
The invention relates to a device for injecting liquid, comprising a piece of tubing on which there is situated at least a first liquid occlusion system. According to the invention, a regulation system (4) is situated upstream from the first occlusion system, the two systems defining an intermediate segment in which the pressure, in the absence of injection, is greater than the pressure that exists downstream from the first occlusion system so as to direct any leak of liquid from the first occlusion system downstream. The invention is applicable to a pump used for injecting contrast liquid for medical imaging.
