<P>PROBLEM TO BE SOLVED: To provide a syringe pump apparatus satisfying drip-proof specifications by transmitting a signal without making a hole in the front face of a dialyzer and having no possibility of disconnection by preventing the moving of a lead wire or FPC. <P>SOLUTION: This syringe pump device which has a feed screw actuated by a motor, pushes a pushing element 4 of the syringe by a linearly movable pusher 5 engaged with the feed screw, and supplies liquid, is provided with a detecting mechanism detecting whether the pushing element is mounted on the pusher or not. The detecting means comprises two conductive plates 12 formed across the whole length of a pipe 7 slidably supporting the pusher electrically insulated from a pipe, a conductive short-circuit member displaced and separated from the two conductive plates when the pushing element is mounted on the pusher, and coming into contact with the two conductive plates and short-circuit them when the pushing element is not mounted on the pusher, and the lead wire 15 liquid-tightly pulled out from one end of the two conductive plates to the outside. <P>COPYRIGHT: (C)2007,JPO&INPIT |
