< Topic >Vis-a-vis the place or group of people where multiple of the human body differs simultaneously, choice and the liquid medicine where the tonnage differs the injection device of the liquid medicine which easily can make inject is offered.SolutionsOn the one hand, flexible pipe 3 for liquid medicine supply, multiple it has the chemical feeding section 1 which possesses the flexible pipe 4 for the chemical feeding on other side on side, as for each chemical feeding section, the multiple flexible pipes where capacity differs inside are internalized. The flexible pipe pushing pressure body which opens and closes liquid medicine path is laid out in these multiple each flexible pipes, inside each flexible pipe while halting or the other flexible pipe summing up the liquid medicine which flows with the liquid medicine which flows by the flexible pipe individually, or multiple simultaneously controlling, in order to supply the liquid medicine of the desire tonnage, is constituted.< Choice figure >Drawing 8【課題】人体の複数の異なる箇所あるいは複数人に対して同時に、量の異なる薬液を選択的かつ容易に注入させることができる薬液の注入装置を提供する。【解決手段】一方側に薬液供給用のパイプ3を、他方側に薬液注入用のパイプ4を有する薬液注入部1を複数備え、各薬液注入部は、内部に流量の異なる複数のパイプが内蔵されている。これら複数の各パイプには薬液経路を開閉するパイプ押圧体は配置され、パイプを個々に、もしくは複数同時に制御することによって、各パイプ内を流れる薬液を停止もしくは他のパイプ内を流れる薬液と合算して所望量の薬液を供給するよう構成されている。【選択図】図8
