Abstract
A chemical liquid injection system with which a chemical liquid in a chemical liquid container can be directly injected into a patient without using an intervening liquid syringe or the like. A trailing end of chemical liquid injection tube 120 that its leading end is connected to the patient is placed at a lower position within chemical liquid container 200. A leading end of liquid supply tube 110 is placed at a upper position within chemical liquid container 200 and a trailing end of liquid supply tube 110 is connected to liquid container 300. Since liquid pressure-feeding mechanism 131 feeds the liquid in liquid container 300 into chemical liquid container 200 from liquid supply tube 110 with pressure, the chemical liquid is directly injected into the patient from chemical liquid container 200 through chemical liquid tube 120.
