FIG. 2 shows the fixture 1 of the first embodiment.
Prior to the description of the fixture 1, the syringe barrel to which the fixture according to this embodiment is attached will be described.
The syringe barrel to which this fixture is attached is a commercially available product comprising an outer tube 20 and a plunger 30 (see FIGS. 3 and 4).
The outer cylinder 20 has a hollow cylindrical shape, and has a connecting portion 21 for connecting an injection needle (not shown) at the distal end and an opening 22 at the proximal end. The opening 22 is provided with a flange 23.
The plunger 30 includes a gasket 31, a plunger rod 32, and a finger pad 33. The gasket 31 is connected to the tip of the plunger rod 32 and is housed inside the outer cylinder 20 in a liquid-tight manner and slidable in the outer cylinder axis direction.
The plunger rod 32 is composed of a cross-shaped member in order to obtain strength while maintaining light weight. A circular finger rest 33 is connected to the base of the plunger rod 32.
