ABSTRACT:
A liquid medicine injecting device for constantly feeding a liquid medicine into a human body at a certain degree. The liquid medicine stored in a liquid medicine receiving portion is fed out therefrom by a pressure means to be supplied into the human body through a flow amount control means and a human body fitting tool such as a needle. Even if there are contaminant and the like in the liquid medicine or if the flow amount control means is folded, twisted, or pressured, the tube is not blocked up to thereby function as a capillary tube and a member for controlling flow amount with a simple structure so that a high productivity and a easy handling can be obtained.
