How to Sterilize Medical Equipment?

Aug. 27, 2021

Disinfection equipment is an important part of modern healthcare because patients are always in contact with surgical tools, syringes and bandages. To ensure the medical safety of your patients, physicians and the environment, you must use medical equipment safely - and that includes keeping them clean and disinfected. These vital equipment components must be cleaned thoroughly and effectively to avoid the possibility of spreading disease from patient to patient.


Some of the methods used to sterilize medical devices are as follows.

1. Steam sterilization

Most sterile processing departments have steam sterilizers called autoclaves. This is because steam cleans many common medical devices, and it is often the safest and least expensive option. Some technicians will only consider using other methods if the medical device is made of heat-sensitive materials or if steam sterilization is not possible. Autoclaves apply intense pressure and heat to destroy all microorganisms on the object.


With steam sterilization, the outer surface of the medical device is cleaned with an appropriate decontaminant. You can prevent damage by wrapping the instrument in paper or cotton before the process begins. For best results, you must expose the steam to all surfaces of the equipment. When you place the equipment in the steam sterilizer, make sure you leave enough space between the parts so that each part can move freely. You should refer to the manufacturer's manual before using the steam sterilizer.

2. Dry Heat Sterilization

When steam cannot penetrate or destroy the instrument, the next logical choice is dry heat. Dry heat is a powerful but slow technique that requires high temperatures and time. Because of this, it is not suitable for many materials, but it is still usually more reliable than various other options. Dry heat sterilization uses air at approximately 340 degrees Fahrenheit to kill microorganisms.


3. Chemical Sterilization

This process involves the preparation of chemical solutions. Some of the chemicals commonly used for sterilization are



Ethylene Oxide

Hydrogen peroxide


These chemicals have the ability to kill a wide range of pathogens and have properties that may be harmful to humans. You completely submerge the equipment in the prepared chemicals for a period of time until the pathogens die. After sterilization, the equipment is rinsed and allowed to dry. Chemical sterilization is not applicable to biological materials, optical fibers and other highly heat-sensitive materials.

4. Plasma gas sterilizer

This type of antivirus device uses a gas plasma based on low-temperature hydrogen peroxide in the chamber to kill any microorganisms, including spores, bacteria, fungi, and viruses, on dental and medical devices. When you add vaporized hydrogen peroxide to the chamber, it sterilizes the enclosed equipment. Once you remove the vapor from the chamber, it creates a lower temperature plasma, which ensures complete disinfection of all equipment.


Oxygen and water are the remainder of this process, making these sterilizers safe for both the environment and medical personnel. While this is a more costly method, it is very effective and an excellent choice for moisture-sensitive medical equipment and tools.


5. Vaporized Hydrogen Peroxide (VHP) Sterilizers

Like plasma sterilization, you can use vaporized hydrogen peroxide in a VHP sterilizer, but without using plasma gas in the sterilization process.VHP sterilization removes moisture from the housing and the generator rapidly injects VHP to achieve the ideal concentration to sterilize the device.


The steam effectively sterilizes the enclosure by removing any microorganisms that may be present. The VHP sterilization cycle time is short, thus allowing for the sterilization of large quantities of equipment.
