摘要 |
A cannula has a front part in a direction of a center axis X with its forward end portion closed. The front part has a plurality of nozzle orifices each of which has an orifice axis Y intersecting the center axis X. Each of the nozzle orifices has a first diameter in a first direction parallel to the center axis X and a second diameter in a second direction perpendicular to the first direction. The first diameter ranges between 0.1 mm and 0.5 mm while the second diameter ranges between 0.1 mm and 0.3 mm so that a liquid in the cannula is jetted from the nozzle orifices in an angle range of 45 degrees towards the forward end portion with respect to the orifice axis.
