液注入機構。[Claims for Utility Model Registration] (1) A chemical liquid injection mechanism that feeds a predetermined amount of chemical liquid through a check valve, wherein the chemical liquid injection mechanism is interposed between a chemical liquid introduction member and a chemical liquid discharge member. 1. A drug solution injection mechanism comprising a cylindrical drug solution injection member made of an elastic body, the drug solution injection member being surrounded by a ring cover having a plurality of holes exposed to the outside. (2) In the chemical liquid injection mechanism described in claim 1 of the utility model registration claim, the check valve includes a cylindrical body defining a chemical liquid passage and a ring body made of an elastic member that closes this passage. The ring body is swollen by the pressure of the first chemical solution, and the chemical solution is delivered to the chemical solution delivery member. On the other hand, when the other drug solution is mixed into the one drug solution via the drug solution injection member, this other A liquid medicine injection mechanism configured to prevent backflow of liquid medicine.
