Abstract
An injection syringe is disclosed which comprises a cylinder equipped at one end with an attachment flange and at the other end, near to an outlet or discharge opening thereof, with a catheter connection. A piston member is insertable into the cylinder, and a container or receptacle is located between the piston member and the outlet or discharge opening. The container is provided with reference fracture locations and is freely displaceable within the cylinder in the lengthwise direction thereof. This container is filled with one of two liquids. After the ejection of the other liquid located within the cylinder externally of the container the container splits open and releases the injection the liquid contained therein. The injection syringe can be used, for instance, for the injection of a contrast agent followed by flushing with a physiological saline or salt solution, but also can be used in all other fields of application where it is desired to apply in timewise succession two liquids.
