<p>The medical aspiration tool (1) is provided with: an outer tube (2) with a cylindrical body (21), a connecting section (22), and a flange (24); a gasket (4) that is held inside the outer tube; and a gasket-operating member (3), which is attached to the gasket. The medical aspiration tool (1) is provided with a movement-restricting member (5), which is fitted on the flange (24) of the outer tube (2) and is for restricting the movement of the gasket-operating member (3) towards the tip. The gasket-operating member (3) is provided with: a body (30), which extends a specified length in the axial direction and can be inserted into the outer tube (2); a gasket-mounting section (33) that extends forward from the tip of the body; and a grip (32), which is provided on the back end of the body (30) and cannot be inserted into the outer tube. The movement-restricting member (5) comprises a section that is fitted on the flange (24) and a protruding section (52) that covers a portion of the opening of the back end of the outer tube (2). The body (30) of the gasket-operating member (3) is provided with: during-rotation contacting sections that contact the protruding section (52) of the movement-restricting member (5) during rotation of the gasket-operating member (3); and protruding section-passing sections, which are provided on the tip of the body (30) and are capable of passing through the protruding section of the movement-restricting member.</p> |
