Abstract
The utility model discloses a disposable anti-pollution injection syringe which comprises a needle tube, a syringe needle seat, a tube cap, a push rod and a piston ring arranged at one end of the push rod. The left portion and the right portion of the push rod are in regular cross-shaped rib plate shapes, the middle portion of the push rod is of a cylinder, the diameter of the cylinder is smaller than that of the needle tube, a notch is formed in the middle portion of the push rod, a through hole is formed in the central portion of the tube cap, an alcohol swab sleeve is arranged on the circumference of the through hole, and the alcohol swab sleeve is contacted with the circumferential face of the middle portion. Due to the fact that the shape of the push rod is designed to be a regular cross-shaped rib plate shape and the middle portion of the push rod is cylindrical, the polluted portion of the push rod is prevented from being contacted with the inner wall of the needle tube, and secondary pollution is avoided. The alcohol swab sleeve contacted with the push rod is added to the tube cap, the push rod is sterilized, pollution is further avoided, and the disposable anti-pollution injection syringe is good in effect, simple in structure, and good in practicality.
