ABSTRACT:
This invention relates to an automatic drip infusion set which is applicable for use in a situation of low atmospheric pressure, not to be suspended from a higher place during application, and which can provide alarm signal accordingly. The device includes a motor to drive an extension rack assembly by means of a speed variator so as to let the push plate which is connected with the rack assembly at the front end compress a compressible drip bottle to infuse the solution contained therein into patient's body smoothly. During moving of the rack assembly, it will trigger a buzzer and a stop control switch respectively so as to stop infusion process and give an audio alarm signal when the solution of the drip bottle is about exhausted.
