The infusion system allows for improved, inexpensive and convenient administration of IV fluids during anesthesia and surgery, using the principles with which practicing anesthesia providers are most comfortable with.

Abstract: The present invention is directed to an apparatus for locating and anesthetizing peripheral nerves. The apparatus of the present invention enables an operator to independently complete a nerve blockade procedure, without the need for an assistant. The apparatus includes a generator which provides an electrical stimulus within a selected range. Adjustable control knobs located on the generator enable an operator to designate the selected amperage range. The apparatus is adapted for accepting a syringe for storing and administering anesthesia, and a tube for carrying the anesthesia from the syringe to a disposable anesthesia needle. An electronic cable connects the needle to the generator for delivering the electrical stimulus to the needle. The apparatus includes a remotely located foot pedal connected to the generator by a coupling cable, which enables the operator to control and modify the magnitude of the electrical stimulus.
