Sterilized safety syringe
First Claim
1. A sterilized safety syringe which is communicated with n air compressor using air feeding pipes for performing infusing drugs into the paient body or extracting the body fluid therefrom, essentially comprising:
- a syringe tube having an injection needle inserted at its tip, the inner part of said tube being formed a cavity and a guide slot being formed between its outer surface and the inner wall of said syringe tube, said guide tube passing through the front wall surface of said syringe tube, and having a protrusion at its front end, a plunger being provided in said cavity and being closely in contact with the inner wall surface of said cavity, the rear end of said syringe tube being in a sealed state where said cavity and said guide slot are communicated with a plurality of air feeding pipes of said air compressor via an air conducting pipe;
a protective cover having a drilled hole at its front end and being provided with a sliding plate at its rear end thereof, said sliding plate being provided with a fixed part at is front portion, and an annular flange at its rear end, wherein said annular flange has a check fitting formed at its front edge;
a sterilizer has a pallet formed at the front end of its main body, and a sterilized cotton swab being affixed to said pallet, a film formed at the front end of said main body being for sealing said pallet, while the rear end of said main body being formed into a plug;
wherein said sliding plate of said protective cover is fitted into said guide slot of said syringe tube and being forcibly in close contact with the wall of said guide slot with said annular flange, said plug formed at the rear end of said sterilizer is plugged into said drilled hole of said protective cover.

Abstract
A sterilized safety syringe comprises a syringe tube, a protective cover, a sterilizer, and an air compressor. The protective cover is slid into a guide slot of the syringe tube with several sliding plates whose rear ends are closely in contact with the wall of the guide slot with their annular flanges. The syringe tube are equipped with several air conducting pipes which are connected with corresponding air feeding pipes of the air compressor. A plug is formed at the rear end of the sterilizer to be plugged into a drilled hole formed on the protective cover. Due to existence of perfectly effective sterilizer, the medical staffs never have to worry about infectant contamination brought about from inadvertent contact with the patient body fluid.
