Abstract
A contrast media injection apparatus has (a) a manifold having a port for connection of catheter, a port for connection of contrast media line, a port for connection of pressure-monitoring line and a port for connection of physiological saline solution line, (b) a pressure-monitoring line connected to the port for connection of pressure-monitoring line and having a cutoff mechanism in the middle, (c) a contrast media line connected to the port for connection of contrast media line, and (d) a contrast media injector connected to the back end of the contrast media line. Using the injection apparatus, the monitoring of pulsation and the injection of contrast media can be conducted under no radiation exposure and, moreover, the injection of contrast media can be conducted simply without requiring the complex operation of valve switching.
