The EO Device Sterilization Process
A majority of medical and surgical appliances in hospitals today are made of substances that have thermal stability. They can, therefore, go through heat, moisture, and sterilization. Ethylene oxide gas is used to sterilize health gadgets that are moist-responsive. The gas keeps the devices safe, and it does not destroy them during the purification procedure. The following system will offer critical guidelines in the EO device sterilization process:
1. Precondition
The disinfection procedure usually begins with the conditioning of the devices. This preconditioning stage is typically implemented in a room equipped to heat and moisten the products. This process ensures sterilization is reproducible irrespective of the outer effects, such as changing weather conditions.
2. Remove the air
Before introducing the EO gas in the sterilizer, it is imperative to remove air content. The process is done through the use of nitrogen gas or carting a deep vacuum. A chain number of repetitions is done to emit the air, hence letting the cleansing process complete safely. The limitation for air removal is determined by the acceptance of the most delicate devices.
3. Humidification
After the air removal process, there is usually a substantial loss of moistness. Before presenting the ethylene oxide, the moist must be replaced. This can be achieved by adding moisture with steam injections. After adding the vapor, the devices are left to settle for a significant amount of time. Usually, this is needed to replace the humidity lost during the air evacuation process.
4. Gas intersection
The ethylene oxide in liquid form is vaporized to gas and added to the room. A minimum amount of gas accumulation is needed to accomplish the sterility of the appliances. The products are then exposed to heat, moisture, and gas at the same time. It is expected that the more complex the device is to sterilize, the longer the time needed.
5. Post-exposure to gas and air
After the intersection, all the gas is eliminated from the room. A series of deep vacuums and nitrogen can chase away the gas trailed with nitrogen wash. The procedure should be done until the gas level is lower than the burnable limitation.
6. Ventilation
Sterilized appliances are placed in a heated chamber to confiscate the unconsumed gas. The room is also kept at an eminent temperature to control any floating ethylene oxide.
In today's decontamination expertise, ethylene oxide remains the most popular sterilization method for medical gadgets. It provides workable solutions to neutralize medical appliances.
