Improving The Environmental Effects Of Nosocomial Infectious Effluents By Using Disposable Suction Liner Bags

Table Of Content

This article was written by Mr. Alireza Hassanali, Mr. Navid Hassanali and Mrs. Niloufar Sharafi and was presented by them at the 10th Congress of Infection Control.



Environmental protection is a key issue, and improper disposal of infectious fluids poses irreparable risks to human health and the environment.

Infectious waste is any waste that is generated during a diagnostic process, treatment, or research activities that include biological experiments.

The management of infectious waste is as vital as its disposal, therefore, it is necessary to use products such as disposable suction bags that collect infectious fluids and prevent them from spreading to the surrounding environment.

In this article, we will investigate the issue of Nosocomial Infections and the methods of preventing the spread of this infection, as well as the management of infectious waste using the new method (Disposable Suction Liner Bag) and the old method (Permanent Suction Canisters).



The study was conducted by the AHP Method model, which is one of the multi-criteria decision-making methods and analyzes the evaluation of parameters quantitatively and qualitatively; also, to use this method and evaluations, Expert Choice software has been used.



It is clear in this study that permanent suction canisters cause hospital infections, increase medical centers’ costs, and increase hospitals’ infectious waste, which costs 10 to 15 times more than other waste due to its infectiousness. Also, the use of disposable suction liner bags not only reduces and controls hospital infections but also reduces the costs of disposal and disposal of infectious waste and treatment of infectious wastes, as well as saving water, electricity, and human resources.



The results of this study allow managers and officials of hospitals and medical centers to know which type of suction canisters to use to improve the level of hospital control and to be familiar with the advantages, disadvantages, risks, and environmental risks caused by suction canisters. to make the best decision in this regard.

Preservation of the environment is a key issue, and incorrect methods of hospital infectious waste management pose irreparable risks to human health and the environment and cause disease.

One of these diseases is hospital infections; Today, in most hospitals and medical centers, we see patients who get hospital infections about 48 to 72 hours after being hospitalized, according to the CDC report, 1 patient out of every 31 hospitalized patients gets hospital infections every day, and the cost associated with Nosocomial Infections in the United States is estimated to be up to $25,000 per infection.

Therefore, it is necessary to use products such as disposable suction bags that turn infectious hospital effluents into waste and prevent the spread of infectious effluents into the environment.

In this presentation, we will examine the management of infectious wastes using the new method (disposable suction liner bags) and the old method (permanent suction canisters).


Hospitals and medical centers always play a vital role in the welfare and health of humanity; One of the problems that medical centers are involved in is the management of waste and hospital effluents, which cause various infections, pathogens, and environmental hazards.

Improper methods of hospital effluent and waste management around the world can have a direct and indirect impact on human health and the environment and cause disease.

One of these diseases is hospital infection; Hospital infection (healthcare-associated infection) is an infection that occurs during the treatment process and is not present when the patient is admitted to the hospital. This infection may occur in different departments of the hospital, care centers, and outpatient departments of health centers. and it is even possible to appear after the patient is discharged from the treatment center.

In addition to patients, hospital infections affect the medical staff and their companions and bring significant costs to hospitals and medical centers.

As a result of the correct management and collection of infectious fluids, the risk of the spread of hospital infections will decrease, and as a result, the death rate from hospital infections will decrease; In the past few decades, compliance with hospital infection control protocols has significantly reduced the number of deaths caused by hospital infections.

In this article, we are going to discuss waste and infectious waste and their collection methods, and the environmental and health effects of suction canisters, as well as compare the effects of permanent canisters and disposable suction liner bags, and finally, the experience of advanced countries in we analyze the use of disposable suction liner bags.


The Necessity Of The Issue

Among the harmful effects of hospital infections are:

  • Increased risk of cancer
  • Gene mutation
  •  Growth and proliferation of pathogenic and infectious bacteria
  •  The outbreak of various diseases

Also, among the effects of the uncontrolled discharge of infectious liquids into the sewage, we can mention damage to the facilities of the collection network and sewage treatment plant, disruption of the sewage treatment process, environmental pollution, and threat to the health of society.

The Necessity Of Converting Infectious Effluent Into Waste

The infectious wastewater treatment process is more complicated than infectious waste.

Vast amounts of water must treat in hospital wastewater to bring the parameters in hospital wastewater to the standard.

Reducing the production of infectious waste (personal protective equipment)



The study was conducted by the AHP Method model, which is one of the powerful decision-making techniques and analyzes the evaluation of parameters quantitatively and qualitatively; also, to use this method and evaluations, Expert Choice software has been used.

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.
