ABSTRACT:
An improved cartridge type syringe capable of being utilized as an anesthetic injector, root canal irrigator, and periodontal pocket irrigator is disclosed which has an aspirating capability as well as a metering capability to measure and control the amount of material injected. The syringe includes means for locating the cartridge within the barrel of the syringe to provide a sealed area adjacent the needle for aspiration purposes. It also includes a means for controlling the amount and rate of flow of the material being injected by utilizing a spring-loaded plunger, a detent carrying drive shaft, and gripping means which are capable of gripping the detents on the drive shaft. The device is constructed so that upon depression of the spring-loaded plunger, the rear seal of the cartridge will be pushed forward a predetermined distance by the drive shaft so as to inject a measured amount of fluid. Upon release of the plunger the spring will return the plunger to its normal position, with the gripping means holding the drive shaft in place. Further repeated depression and release of the plunger will advance the drive shaft the distance of one detent in each case, thereby insuring that only a predetermined amount of liquid is injected at a time.
