Title:
CHEMICAL LIQUID INJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/001881
Kind Code:
A1
Abstract:
A chemical liquid injection device has a piston pressing section (118) for holding
a piston member of a chemical liquid syringe.The piston pressing section (118)
has a flange holding member (123) for holding a flange of the piston member, a piston
contact member (124), and a detection switch (130). The piston contact member
(124) is projected so as to be in contact with the held piston member, and is provided
so that it is displaced when the flange is held and so that, while the piston pressing
section (118) presses the piston member, it is further displaced by force applied
from the flange. Depending on displacement of the piston contact member (124),
the detection switch (130) is switched between open and closed states about the
time at which the flange is held and about the time at which force applied from the
flange in chemical liquid injection reaches a predetermined level.
