What are the two main categories of terminal disinfection?

Terminal disinfection refers to a thorough disinfection of the epidemic site after the source of infection is discharged, transferred, or dies after leaving the epidemic site or terminating the infection state. The aim is to completely eliminate the surviving pathogens that have been disseminated by the sick and left on the room and various objects, so as to render the epidemic site harmless. The more timely and thorough the terminal disinfection, the better the epidemic prevention effect.

It should be pointed out that although disinfection is an important measure to control infectious diseases, it cannot replace other measures such as isolation, lockdown, personal protection and other measures for SARS. For the disinfection of the epidemic site of atypical pneumonia, it must be carried out in a timely manner by the personnel who have mastered the relevant disinfection knowledge under the guidance of the local disease control department, and the terminal disinfection can usually be carried out directly by the disinfection personnel of the local disease prevention and control department. The terminal disinfection of patients with infectious diseases in the hospital is carried out by special personnel arranged by the hospital.

Non-professional disinfection personnel should be trained before carrying out disinfection. In order to ensure the disinfection effect, according to the relevant requirements of the Ministry of Health's "Disinfection Management Measures" and "Disinfection Technical Specifications" (2002 Edition), after receiving the report of the atypical pneumonia epidemic, disinfection measures should be taken within 6 hours in urban areas and within 12 hours in rural areas.

Terminal disinfection Thorough disinfection of the source of infection after it leaves the source of infection. For example, disinfection of the wards and contaminated items of infected patients in hospitals after discharge, transfer or death.

Terminal disinfection is commonly understood to be to thoroughly disinfect the environment, kill all pathogenic microorganisms, and ensure the sterility of the environment. It is mainly used in the environment such as wards and operating rooms where people with infectious diseases have lived, or in places where epidemics have occurred. At present, the use of terminal disinfection technology is the technology to kill all bacteria and viruses in the environment and on the surface of objects, and it is mainly completed by vaporized hydrogen peroxide disinfection robots.

Disinfection can be divided into two categories: ready disinfection and terminal disinfection. Disinfection is carried out during the patient's hospitalization, including the beds, tables, chairs, cabinets, means of transport, eating utensils, leftover meals, sputum, toilets and urine and urine used by the patient; Terminal disinfection is carried out at the time of discharge, transfer, transfer or death of the patient, including showering, changing clothes at discharge; Disinfection of items brought in and various items used in the room.

Failure to sterilize, including: no disinfection treatment at all; There is also the fact that although it has been disinfected, it is not done thoroughly, and there are blank spaces.

Terminal treatment of the teaching room: close the doors and windows of the ward, open the bedside table, medicine|The education network collects and arranges quilts, spreads out quilts, erects mattresses, and fumigates them with disinfectant or irradiates them with ultraviolet light. If there are patients in the same ward, the bedding can be sent to the fumigation room for disinfection or exposure to the sun for 6 hours;

The final disinfection process is as follows.

1.The room is thoroughly closed, fumigated, disinfected and disinfected by ultraviolet radiation for one hour.

2.Remove the blanket and pack it in a double-layer dirt bag, mark it, and send it to the laundry room for disinfection and cleaning.

3.Then the doors and windows are closed, then the table next to the bed is removed, and the quilt is shaken open and hung up, and the mattress is erected.

4.Then use peracetic acid for spray disinfection, wipe the bed with chlorine-containing disinfectant, then go to the table, chair, and floor next to the bed, and then open the doors and windows for ventilation.

Environmental cleaning and terminal disinfection refers to the thorough disinfection of the source of infection after it leaves the source of infection. It can be the disinfection of the residence and contaminated items of patients with infectious diseases after they are hospitalized, transferred or died; It can also be the last disinfection of the ward after the discharge, transfer or death of an infectious disease patient, and the appropriate disinfection method should be selected according to the disinfection object and its contamination situation, requiring the death rate of natural bacteria after disinfection of air or object surfaces = 90%, and the pathogenic microorganisms or target microorganisms should not be detected after disinfection of excrement, secretions or contaminated blood.

Terminal disinfection Terminal disinfection is a comprehensive and thorough disinfection carried out after the outbreak of an infectious disease and before the lockdown of the epidemic area is lifted, in order to eliminate the pathogens that may remain in the epidemic area. Nowadays, terminal disinfection technology is a technology that kills all bacteria and viruses in the environment and on the surface of objects.

1. After the patient is discharged, transferred to another department, and dies, the bed unit should be terminally disinfected.

2. Dismantle the cloth in time, put it in a leak-proof dirt bag, and put it in a leak-proof dirt bag with a red mark for patients with special infections, seal it and send it to the laundry center.

Attention should also be paid to the factors affecting disinfection, such as the disinfection dose (including the intensity and duration of disinfection), the degree of contamination of the disinfectant, the temperature, humidity and pH of the disinfection, the relevant chemical antagonists, the penetration and surface tension of the disinfectant, etc.

Medium level disinfection:

Kills all kinds of pathogenic microorganisms except bacterial spores, including mycobacteria. The commonly used methods for achieving medium level disinfection include the use of iodine disinfectants, alcohols and chlorhexidine iodine compounds, alcohols and quaternary ammonium compounds, phenols and other disinfectants, under specified conditions, with appropriate concentrations and effective action time for disinfection.

It can kill bacterial propagules and lipophilic viruses by chemical disinfection methods and mechanical sterilization methods such as ventilation and flushing. For example, quaternary ammonium salt disinfectants, biguanide disinfectants, etc., under the specified conditions, with appropriate concentration and effective action time for disinfection.

The above content refers to Encyclopedia - Disinfection.

Terminal disinfection refers to the occurrence of a large infectious disease (such as highly pathogenic avian influenza) in a certain area, when the epidemic is extinguished, the sick chickens and threatened groups are culled or harmlessly treated, emergency immunization, after a complete incubation period of the disease, no new cases have occurred, and it is necessary to lift the blockade of the area, before the statutory department sends veterinary experts to carry out acceptance, a comprehensive and thorough disinfection of the area. The aim is to completely eradicate the pathogen of the disease that may be present in the area and ensure that the area is in a pathogen-free state of the disease.

Definition: Terminal disinfection: refers to the treatment of discharged, specialist or deceased patients and their wards, utensils, and medical devices.

First, the concept of disinfection.

Disinfection: refers to the use of physical, chemical and biological methods to kill pathogenic microorganisms in objects and the environment, with the purpose of preventing and preventing the spread and spread of epidemics.

2. The types of disinfection can be divided into three types according to the different purposes of disinfection:

Preventive disinfection. Emergency disinfection.

Terminal disinfection. Terminal disinfection is a comprehensive and thorough disinfection carried out after the outbreak of an infectious disease and before the lockdown of the epidemic area is lifted, in order to eliminate the pathogens that may remain in the epidemic area.

3. Selection criteria for ideal disinfectants: It has strong sterilization power, strong penetration, rapid action and quick effect.

Soluble in water, stable in nature, not easy to oxidize and decompose or flammable, explosive, easy to store. ③：

It has no damaging effect on metal, wood, plastic products, etc., and is non-corrosive. : Strong penetrating power, bactericidal effect is not affected by the presence of organic matter or less.

Easy to use and inexpensive. It has no toxic effect on humans and animals.

4. Patient Treatment:

The handling of the patient is the final step in terminal disinfection:

1) Treatment of discharged patients, the items used for bathing and changing clothes when the patients are recovered and discharged from the hospital must be disinfected before they can be taken out of the ward.

2) The management of deceased patients is divided into the following situations.

1. Disposal of the corpse of patients with general infectious diseases: because after the death of the host, the corpse is put into a special waterproof bag for patients with infectious diseases marked with infection mark, and cremated as soon as possible.

2. Disposal of the corpses of patients with infectious diseases in strict isolation: the corpses are wiped or sprayed with chlorine-containing disinfectant (effective chlorine 2000mg l), and wrapped with a cloth sheet soaked in the above-mentioned disinfectant, and the corpses are placed in a special waterproof bag for infectious disease patients with infection marks, transported by a special sealed vehicle, and cremated as soon as possible.

3. Avoid using bleaching powder to dispose of corpses: because bleaching powder has little effect on reducing the risk of disease and hunger, and it is easy to be quickly neutralized and treated.

There are also harms.

4. Burial of corpses: It should be buried at least 2 meters deep into the ground to prevent the entry of carrion-eating animals, rodents and some flies that can burrow the ground.

Summary. Hello dear.

When using chlorine-containing disinfectants for terminal disinfection, the concentration of the disinfectant needs to be comprehensively considered according to the type of pathogenic microorganisms, the presence of organic matter, and other factors.

In general, that is, for ordinary pathogenic microorganisms, and there is no organic matter, the effective chlorine content of chlorine-containing disinfectant is about 1000mg L.

If the resistance of pathogenic microorganisms is strong, and the disinfection object is present in organic matter such as blood, sputum, pus, excrement or vomit of the patient, it is necessary to increase the concentration of disinfectant, and the effective chlorine content should not be less than 2000mg L.

As for the amount of disinfectant that needs to be used, if it is sprayed, it is generally followed by a dosage of 100ml;If it is a wipe for disinfection, the wiping cloth (dun cloth) should be soaked through;In the case of immersion treatment, make sure that all the objects to be disinfected are submerged in the disinfectant solution.

How much chlorine-based disinfectant is used for terminal disinfection.

Dear, what you want to consult here is how much chlorine-containing disinfectant is used for terminal disinfection, this question?
