Table Of Content

At first, we describe the problem of controlling nosocomial infections, and then we introduce the disposable suction liner bags, which are very effective in this category, and explain their different characteristics.

The risk of nosocomial infections in patients in care units or undergoing surgery is very high.

For example, in the past days, patients who were admitted to hospital in the intensive care unit of a Tehran hospital died of nosocomial infections, while others were treated for longer.

generally, these patients become resistant to antibiotic treatment. In the definition of nosocomial infections, it should be said that those infections that do not exist in the patient at the time of admission and occur during the time of hospitalization.

Statistics show that in industrialized countries, between 5 to 10 percent of hospitalized patients develop nosocomial infections, and this figure rises to about 25 percent in developing countries.

commonly, with contrivance of infection control programs and the use of convenient tools, this number can be reduced by half. Nowadays, with the large investment that is made in the field of infection control and due to the use of equipment and facilities such as disposable containers for nosocomial infections have been significantly reduced.

To understand the importance of investing in infection control and using the right equipment, here are some facts about nosocomial infections published by the World Health Organization.

* Every day, 4,000 children in developing countries die from nosocomial infections.
* One of the consequences of nosocomial infections is the prolongation of patients’ hospital stay. Nosocomial urinary tract infections add approximately 3 days, surgical site infections 10 days, and lung infections due to hospitalization about 20 days.
* For each intensive care unit, the use of appropriate tools such as disposable suction bags can bring up to $ 1,000 per year in medical expenses.

The use of this product is especially important in patients admitted to intensive care units; Because patients admitted to intensive care units are much more prone to nosocomial infections.
This is due to the seriousness of the patients in the intensive care unit, the length of their hospital stay, the ventilation with the device, and the presence of injuries and wounds on their bodies.

Infection through contaminated air and contaminated equipment attached to the patient, such as a suction tube, is more likely to occur during an injury or during a long hospital stay. One of the effective ways to reduce the risk of infection is to use suction bags equipped with antibacterial filters.
Using disposable suction bags can reduce the risk of spreading harmful microorganisms in infectious fluids and suction through air and breathable particles, and can also help control the infection and its risks, especially in the intensive care unit.

Remember that these bags must be equipped with an antibacterial filter to prevent the spread of infection.

The antibacterial filter prevents the microorganisms from leaving the bag with the sucked air, which prevents the microorganisms that grow inside the bag from spreading to the outside environment. Disposable suction bags are a useful way to reduce the risk of infection by contacting staff in various treatment departments with infectious lesions and organic discharge.

Disposable suction bags are the best option to reduce disinfection costs (such as disinfectants, utilities and crew costs).
On the other hand, the ease of use of disposable suction bags is not comparable to washable samples. In addition, since these bags no longer need to be immersed in disinfectant and autoclave solutions, service personnel ‘contact with these bags is minimized and their risk of infection is reduced.

In the United States, 80% of health care centers use disposable bags. In medical centers that use washable dishes instead of disposable ones, these dishes should be washed every 24 hours.
But if we look at it logically, we see that the instructions are difficult and time consuming and therefore usually not done properly by the hospital staff; This puts patients at risk for infection.

To safely dispose of disposable suction bags, they are designed to be completely closed. Therefore, it is enough to take the suction bag out of the support container and destroy it.
As a result, the dish no longer needs to be washed and disinfected and exposed to the risk of infection. Some non-professionals use the old method of washing dishes to drain suctioned liquids into a hospital sewer.
Which is very wrong because of the possibility of transmitting the infection to the environment and groundwater; In addition, wastewater treatment is a very expensive process.

Features and Selection of Suitable Suction Bags

In selecting appropriate and quality suction bags, it is necessary for infection control and medical engineering experts to pay attention to several important features.
Considering that there are various bags available in the market today, in the following, we will examine the features of suitable and quality disposable bags.

Antibacterial Filter to Prevent the Spread of Microorganisms:

It is safe to say that the most important feature in choosing a disposable suction bag is the presence of an antibacterial filter.
A filter is installed in the suctioned liquids to prevent them from spilling. These filters, which are designed both mechanically and non-mechanically, have a great effect in preventing the spread of contaminated liquids around.

In the mechanical type, the suction is stopped by filling the tank and floating the outlet duct towards the vacuum, thus preventing the overflow of liquids to the suction device or central system.
Non-mechanical filters, on the other hand, are made of hydrophobic or hydrophobic materials and, when wet, block the suction duct. Non-mechanical filters are preferred for better performance. Today, this type of filter is obsolete due to the fact that mechanical filters sometimes do not work properly.

Antibacterial Filter to Prevent the Spread of Microorganisms:

Some types of non-mechanical hydrophobic filters, which are highly recommended for use, even prevent the release of suctioned infectious gases, particles, bacteria and microorganisms into the outside environment.

Some of these filters are completely impermeable to particles penetrating up to 0.1 μm wide.
These devices can even prevent the release of toxic gases during electrosurgery and the steam that enters the tank when using tissue cutting tools.

High-quality disposable bags have an antibacterial filter in the suction port.
The antibacterial filter can prevent microorganisms from escaping to the suction source, thus preventing microorganisms from spreading into the environment.
This feature greatly reduces the patient’s risk of infection by preventing the spread of nosocomial infections in the intensive care unit or operating room.

The presence of gelling powder is another important feature of a disposable suction bag.
If the powder has the lethal properties of microorganisms, it has better performance.
With the help of this feature, it can turn the collected liquids into semi-solid gels in a short time.

This will increase the safety of those responsible for cleaning and collecting contaminated and infectious materials in the hospital.
Despite the gelling powder, even if the bags accidentally rupture and spill infectious fluid, the risk of contamination for hospital staff and patients will be significantly lower.
Some of these powders contain additives to remove the odor of suctioned liquids. This factor can also be considered in selecting the desired product.

Dimensions of Disposable Suction Bags

Disposable suction bags are made like ordinary bags and are made of soft polyethylene.
After each use of the bag, the contents are thrown away by people without contact. The resistance of the bag material to impact and pressure is a very important factor that must be observed when buying.
Also keep in mind that it is important that the bag is resistant to fluid leakage at the connection points.

Hospital waste is dumped daily and their low weight is a point that is very important for the staff of the relevant department.
Therefore, since disposable suction bags are disposed of directly after use, their lightness is very important. Disposable suction bags are available in various volumes of 1 liter, 2 liters and 3 liters for use.
Each of these volumes is designed for a specific use. For example, 2-liter bags are suitable for emergency departments, ICU and CCU, and 3-liter bags are suitable for surgery.

Sometimes the volume of suction drained is large. In such cases, it should be possible to use several suction bags at the same time. So a good bag is a bag that can be secreted.

To view the full volume of the bag, it is designed to be graded.
However, some designers design the bag to be opaque or opaque so that the details of the liquid inside the bag are not visible.
But this is completely unprofessional. Because medical personnel should be able to easily identify the volume of suction fluid occupied and replace the bag if necessary.
Therefore, when buying a bag, make sure that the bag is made of transparent material.

Another feature that a good bag should have is that it does not stop filling until the bag is full. This problem occurs when the bag drops due to improper design, after half filling, the pressure drops and the suction operation stops.
Remember to test the bag at the place of purchase to ensure its accuracy.


Due to the high mortality rate due to nosocomial infections, especially in the intensive care unit and operating room, the need to control and prevent nosocomial infections is well understood by managers and medical officials.
By using the relevant equipment to control nosocomial infections, in addition to reducing financial costs, the lives of thousands of patients who die every year due to infection can be saved.
At present, many efforts have been made to cover such equipment and facilities, and it is hoped that in the near future, with the proper use of this product, we will see the improvement of all conditions in the field of control of nosocomial infections.

فاضلاب بیمارستان‌ها باعث ایجاد آلاینده‌های خطرناکی می­شوند که از ترکیبات فعال دارویی میکروارگانیسم ها از جمله باکتری­های مقاوم به آنتی بیوتیک، ژن­ های مقاوم به آنتی بیوتیک، ویروس ­های زنده و دیگر موارد به وجود می­ آیند. مقدار اکسیژن لازم برای تجزیه این میکروارگانیسم­ ها در مقایسه با فاضلاب خانگی بیشتر است.

پسماند بیمارستان­ها را می‌توان به چهار دسته کلی تقسیم کرد، یعنی آب سیاه، آب خاکستری، طوفان و تخلیه خاص. که در مقاله به تعریف هر آنها اشاره شده است.

خاصیت ضد میکروبی نانوذرات مختلف مثل نانوذرات نقره، نانوذرات اکسید مس، نانوذرات اکسید روی، نانوذرات اکسید آهن و غیره در غیرفعال کردن ژن­ های مقاوم به آنتی ­بیوتیک و ویروس ­های زنده موثر است. علاوه بر آن، نانوذرات جذب میکروارگانیسم‌ها و سایر آلاینده‌های موجود در فاضلاب را تسهیل می‌کند که این نانوذرات با سطح بالایی مشخص می‌شوند و در نهایت جذب آلاینده ­های آلی را افزایش می ­دهند.

باکتری ها و ویروس ها به دلیل استفاده بیش از حد آن­ها در تاسیسات پزشکی در پساب بیمارستانی به­ وجود می­ آیند، از ترکیبات فعال دارویی هستند.
