For medical devices, such as syringes, syringes, blood transfusions, infusions and other supplies, the most worrying thing is the infection between the appliances, so disposable appliances are currently widely used. Compared with food, the requirements of this kind of equipment are relatively higher. What is more important here is that its requirements as a cleaning product cannot be wrong, that is to say, there may be bacteria on the equipment, which needs to be sterilized. If it is only sterilization, there may be bacteria that have not been killed. For bacteria that can resist a certain degree of heat, the only way to completely kill bacteria is to do a good job of comprehensive sterilization.
The sterilization treatment mentioned here is the work carried out after the packaging of the instrument. If the instrument is sterilized before packaging, once the instrument is packaged, the bacteria will also enter the packaging with the instrument. Therefore, for the packaging material treated by sterilization, the first thing is to withstand the sterilization treatment. At the same time, after a sterilization, the sterile state must be maintained when it is actually used. This is the biggest feature of disposable instruments in medical instrument packaging.
There are generally three sterilization methods for disposable instruments. The following is mainly selective introduction according to different instruments and requirements.
1.High pressure steam sterilization method
High pressure steam sterilization method, that is, with high temperature, high pressure steam sterilization method. Due to the use of high temperature and high pressure methods, heat-resistant bacteria will also be killed. This method is relatively low in cost and relatively safe because other materials are not used. However, due to the high temperature method, this method is not suitable for medical equipment that is not suitable for high temperature.
2.Sterilization methods of ethylene oxide and ethylened oxygen
This method is actually a ' poison attack ' method, that is, the use of toxic gases to destroy bacteria. Because it is a low temperature treatment method, it has no effect on medical devices. However, due to the use of toxic gases for processing, management in this area is to spend energy, because after sterilization may still have harmful gases left on medical devices.
3.Gamma ray sterilization method
This is the use of a means of radiation disinfection treatment, can be used for high temperature, high pressure treatment can not be the corner, radiation sterilization.
Another advantage of using ' poison attack ' and gamma ray sterilization methods is that sterilization can be performed at the end of the packaging. Therefore, medical equipment first sealed packaging, and then before the shipment of the packaging box sterilization process, in fact, can not be carried out in the initial, but before use, which can reduce the management aspects.
