Abstract

An electronic syringe for use in administering anesthetic and the like injections or for aspirating fluids. The electronic syringe is particularly well suited in dental applications where a precise level of hand control is required. The syringe housing is a compact, pen-style arrangement that may be gripped between the middle and index fingers of the practitioner's hand which allowing for thumb-free operation. Motorized, optionally cordless, operation with speed control and data collection is also provided such that an injection can be preformed on a patient in a steady, painless, non-intimidating manner. When connected to a processing device, the data collection feature is capable of updating a patient database with the mount of anesthetic and the like injected for record keeping purposes.
