Abstract
An electronic peripheral nerve stimulator which may be used to monitor the type of neuromuscular blocks present in a patient following the administration of a muscle relaxant drug. An integrated circuit monostable multivibrator or one-shot is coupled to an amplifier and output stage. Plural integrated astable multivibrators are provided which may be selectively employed to trigger the one-shot circuit to thereby produce stimulating impulses of several predetermined repetition rates and duty cycles useful for producing the so-called 'twitch' and 'tetanus' responses of a patient's digital members. The peripheral nerve stimulator also includes indicating means for the power-on condition of the unit as well as for a low battery charged condition.
