Autoclaves use steam heat to kill any microbial life that may be present on a contaminated load. considered sterile once it has undergone a full sterilization cycle. Once a load is sterile, it can be used without fear of introducing foreign microorganisms into a sensitive environment, such as a laboratory, hospital operating room, food production facility, and so on.
In order to kill a cell with heat, its temperature must be raised to a degree at which the proteins in the cell wall break down and coagulate. Steam is a very efficient medium for heat transference, which makes it an excellent way to destroy microbes. Air, on the other hand, is a very inefficient way to transfer heat/energy because of a concept known as the heat of vaporization.
That energy is what makes steam so much more efficient at destroying microorganisms. When steam encounters a cooler object, it condenses into water. Then, it transfers all of the energy that was used to boil the water directly into the water. This process heats up the cells far more efficiently than air at similar temperatures. This is why we use steam to achieve sterility.
Sterilization cycle
1. Purge Phase: Steam flows through the sterilizer and starts to displace the air; temperature and pressure ramp slightly to a continuous flow purge.
2. Exposure (Sterilization) Phase: During this phase, the autoclave’s control system is programmed to close the exhaust valve, thereby causing the interior temperature and pressure to increase to the desired setpoint. The program then maintains the desired temperature (dwells) until the desired time is reached.
3. Exhaust Phase: Pressure is released from the chamber through an exhaust valve and the interior is restored to an ambient pressure (though contents remain relatively hot).
Autoclave machine, It is a machine used sterilize surgical equipment.
It uses steam heat to kill microbial life that may be present.
Comes in different size depending on the function.
Gravity Displacement type Autoclave
- Lid/Door: It is at the top of the large-scale autoclave, but in the case of a horizontal autoclave, it may be in the front part. The lid should be sealed tightly to prevent contamination and proper sterilization. The top is sealed tightly with the help of an airtight screw.
- Pressure Chamber: It is a vessel whose outer part is made of stainless steel, and the outer coat covers the inner part. The autoclavable materials are placed inside the inner part of the vessel, and the lid is closed tightly.
- Power Switch: It is present at the side of the autoclave and controls the electricity supplied to the auoclave.
- Control Panel: It controls the pressure and temperature inside the vessel and is present beside the main switch.
- Water Level Indicator: It helps indicate the water level of the autoclave. The correct level of water is essential.
- Pressure gauge: It indicates the pressure inside the chamber and is on top of the lid.
- Whistle: It is only present in some types of autoclave, like pressure cooker type, and is on the top of the lid. It helps release the pressure of the chamber before opening the lid after sterilizing the materials.
- Safety valve: This type of valve helps to avoid an accident when the pressure inside the vessel is exceptionally high. It is also present in the lid of the autoclave.
- Electrical heater: It is the heating element attached to the jacket; that heats the water to produce steam.
- Water releasing valve: It helps remove water for replacing and cleaning the water inside the autoclave chamber.
- Thermometer: It is at the top of the lid and displays the temperature inside the chamber.
- Stand: The part present helps the autoclave stand upright and forms the base of the autoclave.
Extra accessories
- Autoclave bag: It is a bag where waste materials are placed for sterilization inside the autoclave chamber.
- Autoclave baskets: Cans or baskets help to safely transfer sterilized material to and from the autoclave. It is available in various sizes; some can have lids or holes.
- Sterilization box: These are stainless steel boxes with lids and venting holes that can be used while sterilizing inside the autoclave.
