The present invention relates to a drug solution injection device for adjusting the amount of the drug solution injected into the blood vessels of the patient, and more particularly to a drug solution controller that can finely adjust the injection amount of the Ringer drug solution according to the condition of the patient.

In general, nutrients, glucose, and other drugs are injected into a patient's blood vessel through a needle in a ringer bottle or pack to help metabolism and restore energy to a patient admitted to a hospital or a person with reduced digestive function. However, conventionally, in order to inject Ringer's blood into a patient's blood vessels, the amount of the patient's blood is adjusted using a Ringer's fluid injector.

According to the configuration, the ringer is filled with a ringer bottle sealed with a rubber stopper at the bottleneck inlet, and one end is composed of a needle part so as to communicate with the inside of the ringer bottle tightly coupled to the stopper, the other end is combined with a needle It is composed of a flexible transparent hose, and the injection volume regulator for controlling the amount of the chemical liquid by reducing and expanding the cross-sectional area of the ringer hose received inward by the pressure roller installed in the inclined grooves flowing on the hose same.
