ABSTRACT:
Disclosed is a syringe having two or more barrels for injection of two or more liquids into a patient in predetermined sequence. The syringe includes a valve, either a slide valve or a rotary valve, which places the barrels one at a time in predetermined sequence in communication in the needle of the syringe. Preferably the syringe is prefilled with the desired injectable liquids and the valve is preset so that the barrel containing the first liquid to be dispensed is in communication in the needle.
