The invention aims at providing an adjustable and controllable spraying device for clinical
local anesthesia, and relates to the technical field of
medical instruments.When the adjustable and controllable spraying device is used, an
anesthesia apparatus is detachably installed on a liquid pushing device, the position of a limiting plate is adjusted by rotating a screw of the
anesthesia apparatus according to the amount of
anesthetic, a
piston head is pushed to the head end of an
anesthesia cylinder, and then the
anesthetic cylinder is opened; the
electromagnetic valve is controlled to be closed through the control button, the
infusion pump is controlled through the pedal controller to convey liquid in the
medicine storage box into the anesthesia cylinder through the guide
pipe and the
medicine conveying
pipe, the
piston head moves backwards to the limiting plate and makes contact with the switch on the limiting plate, the switch is triggered to control the
infusion pump to stop infusion, and quantitative infusion is achieved. The amount of the
anesthetic can be conveniently and accurately controlled; the
electromagnetic valve is controlled to be opened through the control button, the motor is controlled to drive the lead screw to rotate, the push plate is driven to slide, the push rod is pushed,
medicine in the anesthesia cylinder is pushed to the spray head and sprayed out through the spray head, and automatic medicine spraying is achieved.
