Peripheral Electrical Nerve Stimulator

Peripheral Electrical Nerve Stimulator


        Used to locate the nerve by causing depolarization with electrical pulses and contracting the muscles or causing sensation in the distributed area.

        Designed for an impulse frequency of  1-2 HZ and a stimulus amplitude of 0-5 mA.

        Desired threshold current = 0.2-0.5 mA.



Stimulator Needles

        Currently use 22 ga. needles in multiple lengths (2-4-6 inch) with an integrated electrode wire in the hub and extension tubing to inject local anesthetic.

        Note:  All nerve blocks can be performed by 2-inch needle, except sciatic blocks which require a longer needle.
