A continuous liquid medicine injector (10) has a cylindrical body (11). A liquid medicine receiving portion is provided at one end of the cylindrical portion (13), and an instrument inserted into a human body which may be a needle (52) is provided at the other end thereof. Two ends of a tubular rubber-like elastic film (31) are fixed to an intermediate portion of the cylindrical body. A liquid medicine flow into the elastic film through a through-hole (11a) formed in the cylindrical body to inflate the elastic film, and the elastic film which has been inflated forms a pressurizing means of the liquid medicine. A thin tube (21) having a predetermined inner diameter and a predetermined length is disposed within the cylindrical body. One end of the thin tube is made to communicate with the instrument inserted into the human body. |
