Title:
CONTROLLER FOR INJECTION OF MEDICINE
Document Type and Number:
Japanese Patent JP3764292
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To eliminate the injecting delay of medicine that is caused by the distance set between a medicine injector and an injecting point and to make instantaneously changeable the medicine injection rate at the injecting point by controlling the opening degree of an additional flow rate control valve according to the calculated medicine flow rate set value and the medicine flow rate that is detected by a detector means.
SOLUTION: A medicine flow meter 4 is set to an injecting pipe 2 as a medicine flow rate detector means which detects the medicine flow rate after the additional water flowing in the pipe 2 is added, and an additional water flow rate control valve 5 is set to an additional water pipe 3 to control the additional water flow rate flowing through the pipe 3. Then a medicine flow rate set value calculation means 7 calculates the medicine flow rate set value from the medicine injection rate set at an injecting point. An additional water flow rate control valve control means 9 controls the opening degree of the valve 5 according to the medicine flow rate set value calculated by the means 7 and the medicine flow rate detected by the meter 4.
