With the continuous development of the pharmaceutical industry, plastic syringes have also been continuously improved, replacing the original glass material with a more excellent plastic material. The plastic syringe has a simple structure, mainly composed of a sleeve, a push rod, a protective cap and a piston. The push rod can print the scale, which can effectively ensure the accuracy of medication.
The aseptic treatment of plastic syringes mainly includes the sterilization treatment of ethylene oxide and cobalt 60. The sterilization of ethylene oxide is mainly gas sterilization. Currently, medical devices are widely sterilized by using ethylene oxide. Cobalt 60 sterilization is radiation sterilization, which is relatively costly. The main advantages of both are as follows:
Plastic syringe ethylene oxide sterilization has the following advantages:
1. Can kill all microorganisms, including bacterial spores.
2. the sterilized articles can be wrapped, packaged as a whole, and can be kept sterile before use.
3. Does not corrode plastic, metal and rubber;
4. can penetrate irregular shapes.
The characteristics of cobalt 60 sterilization for irradiation sterilization are:
1. The penetrating power is very strong, and it is not necessary to disassemble the product packaging during irradiation, which can ensure that all parts of the product are uniformly irradiated, and the sterilization effect can be achieved.
2. Irradiation sterilization is carried out under normal temperature and normal pressure, no residue, no pollution, no residue, convenient and fast.
