For injection of lidocaine subcutaneously or intramuscularly for infiltration and nerve block.

The Wand™ is a computer controlled syringe consisting of a stationary motor housing which includes a metal piston whose speed of advance is regulated by a foot switch thus controlling the flow rate of anesthetic being injected. The device utilizes hypodermic needles and standard 1.8mm pre-filled carpules manufactured by various third parties. The anesthetic agent reaches the needle by means of a length of flexible vinyl tubing. The handpiece is made of rigid PVC. The holster containing the anesthetic carpule, the tubing and the handpiece are sold in a sterile condition as a disposable assembly for one-time use. The materials, principal of operation and intended use are the same as other marketed piston and cartridge syringes.
