摘要：
The present relates to an automatic insulin pump, which allows the rotary shaft only to rotate piston advancing means to remove vertical load applied to a rotary shaft, thereby improving durability thereof. The insulin pump includes: an injector having a syringe for containing insulin therein, and a piston inserted into the rear end of the syringe for providing the syringe with insulin discharge pressure a housing having an injector receiving space formed in an appropriate position thereof, the injector receiving space having a partition wall formed at the rear end thereof a rotary shaft having a non-circular section and a predetermined length power supply means for rotating the rotary shaft at a predetermined speed a push plate assembly for providing the piston with ahead power by pushing the piston, the push plate assembly having a disk part having a male screw formed on the outer circumferential surface thereof and a coupling hole axially coupled with the rotary shaft at the central portion thereof to allow for forward and backward movement of the rotary shaft, which passes through the coupling hole and a hollow cylindrical type push plate case inserted into the injector receiving space of the rear end of the syringe, for the piston to pass therethrough, the push plate case having a female screw formed on the inner circumferential surface thereof to be Jg coupled with the male screw of the disk part for allowing the disk part £? to carry out a spirally forward and backward movement.
