ABSTRACT:
A multiple barrel syringe apparatus is provided for selectively dispensing fluids. A body has a plurality of pie shaped bores therein, each bore being open at one end and narrowing at the other end into separate smaller bores opening at the other end thereof. A needle cannula having a bore therethrough or a stopcock may be attached to the other end of the body over a plurality of smaller bores so that each pie-shaped bore can have a liquid therein dispensed through a single bore. A plurality of plungers are each pie shaped for fitting in one of the cylindrical body pie shaped bores and each plunger has a groove extending down one side having a plurality of ratchet teeth therein. A plurality of pawls are formed on the cylindrical body, one pawl positioned adjacent each cylindrical body pie shaped bore on one end for selectively engaging the ratchet teeth in the groove of one plunger so that each plunger can be locked in a different position.
