Description

Gas sterilization equipment

The invention relates to a gas sterilization device, in particular to a device for sterilizing biological materials by using ozone.

Generally, a biological material refers to a material existing in a living body or a material produced through an organism, so that the biological material has a very high biocompatibility, and thus is widely used for medical purposes, in order to ensure safe use, biological materials. A rigorous sterilization procedure is required to be applied to the organism.

At present, the disinfection methods used in biological materials are:

(1) 75% alcohol disinfection: the biological material is immersed in 75% alcohol. The disadvantage is that the biological material is easily denatured, and the step of cleaning the biological material is required before use, and there is a problem that the cleaning is incomplete and the alcohol remains. ;

(2) Irradiation and disinfection: the use of radiation or ultraviolet light to illuminate the biological material for disinfection, but the excessive energy of the radiation may destroy the structure of the biological material, and must be carried out in a special place and equipment, and the ultraviolet light penetration is poor. The disinfection effect of the three-dimensional biological material is not good;

(3) Disinfection of chemical agents: the use of chemical agents added to biological materials to achieve the purpose of disinfection and sterilization, but most of the chemicals used are toxic and difficult to remove, and the range of application is small, so the practicality is not good;

(4) High temperature and high pressure sterilization: This method is very easy to denature biological materials, and even the activity completely disappears.

In combination with the above sterilization and sterilization methods, each has its own shortcomings. Therefore, how to design a sterilization device that can be easily and widely used and achieves no damage to biological materials is a problem that people in the field are eager to solve.
