The present invention relates to a drug filling and flow control apparatus for a drug injection apparatus, which fills the drug injection apparatus with a drug for injecting the latter into a patient, or controls the flow of the filled drug. The present invention also relates to a drug injection apparatus comprising the drug filling and flow control apparatus. The drug filling and flow control apparatus of the present invention is configured such that a one-way valve (40) is installed at a drug filling port (24) which is filled with a drug from an external source through a syringe, thereby preventing the backflow of the drug and the ingress of outside air, thus preventing the contamination of the drug. |
