The syringe is cylindrical; the push rod is positioned in the syringe; an elastic and compressible latex sleeve is arranged in the syringe; the front end of the latex sleeve is fixed on the inner wall of the front end of the syringe; the rear end of the latex sleeve is fixed at the front end of the push rod and moves to and fro in the syringe along with the push rod. When medicines are dispensed, the compressed latex sleeve is together expanded by pushing the push rod, and then liquid medicines enter into the latex sleeve in the syringe; the liquid medicines are always positioned in the latex sleeve no matter how many times the push rod is pushed, and do not directly contact the inner wall of the syringe, thus the liquid medicines are not polluted.
