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.

Injection head and chemical injection device comprising same

Provided is an injector in which adhesion between a stator and a rotor of an ultrasonic motor can be released efficiently. An injector () which injects a chemical liquid includes: an ultrasonic motor unit () including an ultrasonic motor (); a drive mechanism () to be driven by the ultrasonic motor unit () so as to feed the chemical liquid when the ultrasonic motor () rotates forwardly; and a control device () which controls the ultrasonic motor () of the ultrasonic motor unit (). The ultrasonic motor () includes a stator () and a rotor (), and the control device () controls the ultrasonic motor () to alternately repeat forward rotation and reverse rotation so that adhesion between the stator () and the rotor () is released.

Injector and control method for an ultrasonic motor

The injection apparatusis provided that can allow repair or replacement of an actuatorwhile maintaining a drip-proof state, and that can further maintain the drip-proof state without a cover. The injection apparatusincludes a syringe holderon which a syringe filled with a liquid medicine is mounted, a presserthat pushes out the liquid medicine from the mounted syringe, an actuatorthat moves the presserforward or backward, the actuatorincluding a feed screw nut, a feed screw shaft, a motor, and a transmission mechanismthat transmits rotation from the motorto the feed screw shaft, wherein the feed screw nut, the feed screw shaft, the motor, and the transmission mechanismare housed in a caseof the actuator
