Abstract

PURPOSE:To facilitate the angle change during manual work by forming a plurality of guide channels having respective determined angles for removably and attachably installing a sticking needle on the installation part of the sticking needle. CONSTITUTION:A sticking adaptor 15 has a mounting part 13 mounted on a probe body 11 and a needle guide part 14 to which a sticking needle is installed. The mounting part 13 is circularly formed, and the needle guide part 14 is removably and attachable mounted on the mounting part 13 through the engaging part 17 on the side part thereof. The needle guide part 14 has guide channels 1-8 for installing a sticking needle 20. At the time of sticking, the sticking needle 20 is installed into the guide channel and guided to a concerned part 25 along the guide channel to extract body fluids of the concerned part. When the sticking angle of the sticking needle is changed during manual work, the sticking needle is removed and mounted into the guide channel having a determined angle. Hence, the angle change during the manual work can be facilitated.
