ABSTRACT:
A drug delivery system utilizes a hand piece adapted to receive a probe. The hand piece may be made of a first segment and a second segment connected to one another by a swivel joint to accommodate a user's position and preference for switches provided thereon. Alternatively, the switches may be mounted on rotatable bases. A base unit connected to the hand piece delivers a substance to the hand piece via a drug line. The base unit may further include a nerve stimulator for transmitting current to the probe. A drug switch on the hand piece selectively activates a drug delivery and suction to facilitate aspiration. A current switch on the hand piece selectively delivers electric current to the probe. In practice, the hand piece of the invention may be used by a single operator operating an ultrasound wand with a first hand and operating the hand piece with a second hand, thereby reducing personnel typically required to perform certain tasks.
