The present disclosure relates to a compound represented by the formula (I): wherein each symbol is as defined in the description, or a salt thereof.

Abstract: A chemical-liquid injection head including a syringe holding unit which holds a syringe in which a piston member is slidably inserted into a cylinder member having a circular cylindrical shape, a piston driving mechanism having a ram member for moving the piston member of the syringe, and a first light emitting portion which emits light with a first color and illuminates the syringe and a second light emitting portion which emits light with a second color and illuminates the syringe. The first light emitting portion and the second light emitting portion, viewed in a posture at the time of use of the injection head, are provided at an upper side of the ram member.

Abstract: The injection apparatus 100 is provided that can allow repair or replacement of an actuator 130 while maintaining a drip-proof state, and that can further maintain the drip-proof state without a cover. The injection apparatus 100 includes a syringe holder 110 on which a syringe filled with a liquid medicine is mounted, a presser 115 that pushes out the liquid medicine from the mounted syringe, an actuator 130 that moves the presser 115 forward or backward, the actuator 130 including a feed screw nut 134, a feed screw shaft 133, a motor 132, and a transmission mechanism 180 that transmits rotation from the motor 132 to the feed screw shaft 133, wherein the feed screw nut 134, the feed screw shaft 133, the motor 132, and the transmission mechanism 180 are housed in a case 170 of the actuator 130.

Abstract: A safe and easy handling of a chemical-liquid circuit having various components. The opening/closing unit drive mechanism includes an opening/closing unit holder which detachably holds an opening/closing unit which includes a housing having flow channels and a piston for opening and closing the flow channels which is movably provided to the housing, a hook to be engaged with the piston of the opening/closing unit, which is disposed leaving a space from the opening/closing unit holder, and a linear motion mechanism which moves the hook back and forth. The opening/closing unit holder is movably supported between a first position at which the piston is engaged with the hook and a second position at which the piston is not engaged with the hook.

Abstract: A liquid injection system which can be checked that that a liquid syringe is appropriately mounted on a chemical liquid injector and the liquid syringe is filled with a liquid at a time. Pattern 400 appearing as a predetermined shape when it is viewed from above through liquid syringe 200 filled with transparent liquid L is divided between a lower surface of liquid syringe 200 and an upper surface of chemical liquid injector 100. When liquid syringe 200 is appropriately held by chemical liquid injector 100, the pattern on the lower surface of liquid syringe 200 and the pattern on the upper surface of chemical liquid injector 100 are properly combined. If liquid syringe 200 is filled with a transparent liquid in this state, the combined pattern is viewed as the predetermined shape from above liquid syringe 200. The shape can be seen to check that the liquid syringe 200 is appropriately held and filled with liquid L at a time.
