Provided is an apparatus for regulating a liquid medicine. The apparatus includes a fixing member, a connection member, a regulation member, a purge member, an elastic member, and a locking member. The fixing member guides a flow of the liquid medicine. The connection member is fixedly inserted into an inner side of the fixing member. The regulation member is inserted into the inner side of the fixing member with surrounding the connection member in order to regulate an amount of the liquid medicine. The purge member is connected with the connection member to regulate the flow of the liquid medicine by pushing the connection member when being given a predetermined pressure. The elastic member is mounted on the connection member to return the connection member to an original position of the connection member after release of the predetermined pressure. The locking member is positioned between a top surface of the regulation member and a bottom surface of the purge member to lock movements of the purge member and the regulation member. The regulation member includes an inclined path formed on a top surface thereof and the locking member ascends along the inclined path and then is fixed, thereby locking the movements of the purge member and the regulation member. The apparatus is locked after the amount of the liquid medicine to be injected is set, so that the apparatus can be prevented from being arbitrarily operated, thereby allowing stable injection of the liquid medicine.
