  • The use of all previous surgical medical material to its use needs to be sterilized. These different types from instruments and mechanical pieces are placed within a sterilization bag that has a region that is permeable to the gas but impermeable to the germs and the bacteria. Later to seal the bag, the sterilization is realized with a method using steam of high temperature, ethylene oxide gas, (EOG) and similar. After the sterilization of the instruments until their use in surgery, the instruments are stored within the bag, and during the surgery or the treatment, the bag is opened and the instruments are used.
  • At present the designs of existing bags in the market present some disadvantages as it is the fact that the access to the material sterilized placed inside the bag does not allow being of efficient and fast way because the bag lacks devices and necessary fittings for it. Another disadvantage of the present existing designs is the fact that between the used materials they are tweezers and bistouries of weights and forms that break the bags that lack a sufficiently resistant bottom for these. In addition another disadvantage is the fact that they lack visual indicators that allow to visualize if the bag is perfectly sealed and indicators that allows to distinguish the type of sterilization to that they were put under and if the sterilization were carried out in correct form, to guarantee so much the security in the seal of the bag like in the sterilization process.
