Anesthesia injection system and method
First Claim
1. An injection system comprising a pump connected to a switch assembly, the pump housing a system control module in communication with the switch assembly and the pump, the switch assembly defined by a switch, a mount, a bracket attached to the mount and carrying the switch, and a lever displaceable from a neutral position to a first position and from a neutral position to a second position, the system control module configured to detect the orientation of the lever, wherein detection of the lever in the first position by the system control module engages a predetermined first action by the pump, wherein detection of the lever in the second position by the system control module engages a predetermined second action by the pump, the first action and the second action defined as an aspiration action and an injection action, respectively, wherein the mount is sized and shaped to receive and frictionally engage an exterior surface of an ultrasound transducer probe, and wherein the switch assembly is separate from any control of the ultrasound transducer probe and coupled thereto.

Abstract
An injection system for the independent administration of imaging-guided injections utilizing the hand-on-needle technique including a pressure-sensitive pump and a switch assembly is provided. The switch assembly is adjustably mounted to a probe with a releasable mount, and includes a displaceable lever that can be displaced from a neutral position to a first position to initiate an aspiration event at the needle and from a neutral position to a second position to initiate an injection event at the needle. The displaceable lever and the pressure-sensitive pump are in electronic communication with a control module, which includes programmable logic executed by a processor to send and receive electronic communication(s) from the pump and switch, including when to continue and/or terminate aspiration and injection events at the needle.
