Top 1 reputable medical sterilization service supplier in Hanoi

What is sterilization?



Sterilization means the process of killing all microorganisms including the spores and inactivating viruses or completely removing them from the object to be sterilized.

In medicine, all materials that are introduced into the patient’s body or used in environments requiring maximum sterility must be sterilized in all copies, such as syringes, injections, sutures, masks, and in medicine. Some other tools….

Why need sterilization?

Ensure maximum from the penetration of bacteria, avoid the spread, cross-contamination.

The danger of bacteria in daily objects 

A bacterium is a microscopic microorganism. They are found everywhere in soil, water, radioactive waste, hot springs, and in the symbiotic and parasitic form with other organisms. Even in what appears to be the most sterile place is a spaceship, bacteria can thrive if manned. In particular, bacteria are mostly microorganisms that are harmful to humans, which is due to the ability of bacteria to cause disease and spread disease.

There are no parts of the human body that bacteria refuse to attack. Certain types of bacteria can cause illness in humans, such as cholera, diphtheria, dysentery, plague, pneumonia, tuberculosis, typhoid, and many others.

The danger of viruses daily objects 

Like bacteria, viruses are microscopic parasites, but much smaller. They lack the ability to grow and reproduce outside of the host’s body and cannot reproduce on its own. However, once the virus infects a sensitive cell, it is able to manipulate the cellular machinery to make more viruses. Most viruses are the cause of the disease. The world experienced the 2014 Ebola outbreak in West Africa, the 2009 swine flu pandemic. And now the Covid-19 pandemic is endangering everyone.

Bacteria, viruses are all around us, even Coronavirus. It can easily spread germs directly when an infected person coughs, sneezes at you, or gets on top of other objects. Items for everyday use appear to be safe, but they are the vector most at risk of transmission.

Protect both users and people in close contact, especially in environments such as clean rooms, operating rooms.

Methods of sterilization in medical rooms and laboratories

This process can be achieved by a combination of heat, chemicals, irradiation, high pressure and filtration such as under-pressure steam, dry heat, ultraviolet radiation, gas sterilizers, etc. Effective engineering is essential to laboratory work and this negligence can lead to serious consequences.

Heat method

This is the most common method. Heat is used to destroy microorganisms in the substance. The degree is affected by temperature and heating time. On the basis of the type of heat used, the thermal method is classified into two categories: steam sterilization and dry heat sterilization.

Radiation method

This method involves exposing the packaged materials to radiation (UV rays, X-rays, gamma rays) for sterilization. The main difference between the different types of radiation is their penetration and hence their effectiveness. UV rays have low penetration and are therefore less effective, but are relatively safe and can be used for small area sterilization. X-rays and gamma rays have further penetrating power and are therefore more effective for large-scale sterilization. However, it is more dangerous and therefore requires special attention.

Chemical method

Heating is a reliable method for removing all bacteria, but is not always appropriate as it can damage the material being sterilized. In that case, chemical methods for sterilization to be used include the use of hazardous liquids and toxic gases without affecting the material. Sterilizers are effective when using gases because they penetrate quickly into materials such as steam. The gases commonly used for sterilization are combinations of Ethylene Oxide (EO gas) and carbon-dioxide (CO2).

Through the application of vacuum, this method is able to effectively penetrate the surface of almost any item. And the fact that the temperature in the process is kept lower than that of other technologies makes it an ideal process for sterilizing a wide range of materials, especially materials that cannot withstand high temperatures.

This type of technology uses the main raw material EO gas, also known as Ethylene Oxide. Ethylene Oxide is a flammable and explosive colorless gas, so special attention should be paid to the standards of the following:

Ethylene Oxide gas concentration: from 450 to 1200 mg / l

Relative humidity from 40% to 80%

Temperature: from 37 to 63 ° C

Contact time: from 1 to 6 hours

Why the EO method is a better choice than heat to sterilize?

As we all know, steam and dry heat sterilization is the ideal choice to kill all bacteria, fungi and spores. This is the simplest, most effective method in terms of cost as well as time. But the steam cannot be applied to all materials and tools. Advancement in the medical treatment process has led to the inability to use heat to sterilize sophisticated medical instruments. The reason is that these materials cannot withstand the high temperatures or humidity from water vapor. Therefore, it requires an alternative and that is where Ethylene Oxide comes in.

The materials commonly sterilized with EO gas can be listed below:

  • Sophisticated equipment
  • Catheter
  • Electronic integrated device
  • Multi-lumen tube
  • Stent
  • Bandage
  • Materials with a polymer composition
