Abstract

A micro syringe which can be attached to the end of a micro intravascular endoscope for drug injection is fabricated and its characteristic is tested. The syringe consists of a drug chamber and an actuator chamber which are separated by a silicone rubber membrane. The drug chamber is filled with liquid drug by the membrance actuation caused by the vaporization and condensation of the working liquid in the actuator chamber. The liquid drug is ejected by the electrolysis of the working liquid. The membrane deflection by each actuation method has been measured. The liquid ejection image has been captured during the electrolysis of the electrolyte. Also, the successful operation of the micro syringe under the normal blood pressure was verified.
