摘要： A liquid medicine administration device (10) includes a cylindrical body (12) having a housing space (26) inside, a tube (14) housed in the cylindrical body (12) and filled with a liquid medicine, and a plunger mechanism (16) provided movably in an axial direction with respect to the cylindrical body (12) and having a pressing member (60) that presses a proximal end of the tube (14) toward a distal end side to push out the liquid medicine. The tube (14) is formed in a tubular shape, and has a through hole (36) for discharging a liquid medicine at the distal end of the tube (14). The tube (14) is compressed along the axial direction along with movement of the pressing member (60), and is deformable toward a central axis (Z) side, that is, radially inward.

摘要： Provided is an infusion pump having a configuration in which infusion tubes having different outer diameters can be easily positioned and which facilitates miniaturization.
An infusion pump according to the present disclosure is an infusion pump including a main body to which an infusion tube is fixed. The main body includes: a first fixing unit; a second fixing unit which is movable between a pressing position and a release position; an urging unit which urges the second fixing unit toward the release position; a transmission unit which is disposed in one of the first fixing unit and the second fixing unit and transmits a predetermined signal toward the infusion tube sandwiched between the first fixing unit and the second fixing unit; and a reception unit which is disposed in the other of the first fixing unit and the second fixing unit and receives a signal transmitted from the transmission unit. The second fixing unit is movable between the pressing position and the release position by being rotated with respect to a rotary shaft. The urging unit is formed of an urging member mounted on the rotary shaft.
