The present invention provides a medicinal fluid supply control device capable of performing a quick "priming" which is a preparatory operation for injecting medicinal fluid into a patient by removing air in the medicinal fluid or between the medicinal fluid and the medicinal fluid in advance by means of a filter for removing air provided on a discharge path inside the medicinal fluid supply control device, and reducing unnecessary loss of the medicinal fluid, generated during a discharge of the medicinal fluid in order to remove the air in the medicinal fluid or between the medicinal fluid and the medicinal fluid. In addition, the present invention provides a medicinal fluid supply control device capable of quickly injecting an increased amount of medicinal fluid, by removing air between the medicinal fluid and the medicinal fluid, which can be generated by a difference in flow rate of the medicinal fluid flowing in the medicinal fluid supply control device, by means of a filter for removing air provided on a discharge path inside the medicinal fluid supply control device, and of directly and easily adjusting, by a user, the injection amount of the medicinal fluid as required.本發明提供一種藥液供給調節裝置,其利用在藥液供給調節裝置內部的排出路徑上具備的空氣去除用篩檢程式而事先去除藥液內或藥液與藥液之間的空氣,從而能夠加快用於向患者注射藥液的準備工作即“啟動(priming)”,能夠減少為了去除藥液內或藥液與藥液之間的空氣而排出藥液時發生的不必要的藥液損失。另外,本發明提供一種藥液供給調節裝置,其利用在藥液供給調節裝置內部的排出路徑上具備的空氣去除用篩檢程式去除由於在藥液供給調節裝置內流動的藥液的流動速度差而可能發生的藥液與藥液之間的空氣,從而能夠進行迅速的藥液增量注入,使用者能夠根據需要而直接簡便地調節藥液的注入量。
