How to properly handle used masks?

According to the National Health and Welfare Committee WeChat public account Health China, the used masks carry a large number of microorganisms, such as viruses and oral bacteria, and there may be a great risk of infection.

Points to note when removing the mask:

· Do not touch the outer surface of the mask, because you may infect yourself.

· Do not touch the inner surface of the mask (self is a patient), because it may infect others.

· Do not touch the masks used by others because they may cross-infect.

· Do not put it directly in the bag, pocket, etc., because there may be a risk of persistent infection.

Some error handling methods:

╳Boiling water

High temperature is indeed a method of disinfection, such as boiling, and it is simple and easy to operate. However, if you use a boiling water mask, you must place the mask on the container or countertop to avoid contaminating the container or countertop. Secondly, boiling water can not meet the continuous high temperature required for disinfection and the time is not enough. It may only kill some pathogens . Therefore, boiling water treatment is not recommended.

╳ Incineration

Similarly, the principle of incineration is high temperature disinfection. However, incineration will pollute the environment in the first place, and it will cause potential safety hazards in the second, and there is no such fixed place in the third. Therefore, personal incineration is not recommended.

╳ Throw away after shredding

Although the starting point for shredding the masks to prevent recycling by people with ulterior motives is good, there is a great risk of infection. Therefore, shredding is also not recommended.

The correct way to deal with used masks:

Since the development of human civilization, there are dozens of ways to kill pathogenic microorganisms, including pressure steam, ultraviolet light, high temperature, medical alcohol, chlorine (bromine) disinfectant, and so on. However, the use of a oxen knife to kill chickens is certainly suitable for our ordinary people to choose a relatively simple, efficient and safe way. In this regard, Healthy China recommended.

√ When in a medical institution

All masks used in medical institutions should be directly put into medical waste garbage bags. These masks, as medical waste, will be centrally disposed by professional disposal agencies.

√ Usually

People who are suspected of having an infectious disease should hand over the used masks to the corresponding staff during medical treatment or investigation and disposal as medical waste.

For people with fever, cough, sputum, sneezing and other symptoms, or people who have been in contact with such people, it is recommended to throw the mask to the trash first, then use 5% 84 disinfectant according to the 1:99 ratio Sprinkle on the mask for treatment. If there is no disinfectant, you can also use a sealed bag / fresh-keeping bag, seal the mask and throw it into the trash.

For ordinary people, because of the low risk, the used masks can be directly thrown into the trash.

After handling the mask, remember to perform hand hygiene.

How to wear a mask correctly?

It is understood that medical surgical masks have three layers, from the outside to the inside are the waterproof layer, the filter layer, and the comfort layer. The comfort layer is a layer of non-woven fabric. When wearing, the white non-woven fabric faces inwards, and the blue waterproof layer faces outwards. Fit the nose and smooth the cheeks so that there is no gap between the mask and the face.

Steps to wear a mask:

(1) Pull the opening mask to both sides, and the fixing band is loosened every 2-4cm so that the nose clip is located above the mask;

(2) Use a mask against the chin, put on the mask upwards, and place the straps on the top of the head and behind the head;

(3) Pull the earrings behind the ears, and then adjust the earrings;

(4) Press the nose clip with both hands to make the nose clip fit perfectly with the nose, so that the mask fits your face shape;

(5) Check the tightness of the mask and adjust to the most comfortable state.

Classification and applicable environment of disposable protective gloves

Classification and applicable environment of disposable protective gloves1. Insulated gloves for live working refers to a kind of insulating gloves that the operator wears on his hands for electrical insulation when performing live work on electrical equipment with an AC voltage of 10 kV and below (or DC electrical equipment of the corresponding voltage level). The product model, appearance size and technical requirements shall comply with the provisions of “General Technical Conditions for Insulated Gloves for Live Working”. Insulated gloves Gloves must have good electrical insulation properties. At the same time, it needs good tensile strength and elongation at break, as well as puncture resistance, aging resistance, flame resistance and low temperature resistance. 2. Acid and alkali resistant gloves are protective products to prevent acid and alkali damage to the hands. The quality should meet the requirements of “Acid (Alkali) Gloves”. Gloves are not allowed to have defects such as frost spray, brittleness, stickiness and damage. The non-leakage of the glove means: it must be airtight, and under certain pressure, no air leakage is allowed. Such gloves can be divided into rubber acid and alkali resistant gloves, latex acid and alkali resistant gloves, plastic acid and alkali resistant gloves, plastic impregnated acid and alkali resistant gloves, etc. according to the material. Waterproof gloves and antivirus gloves can be replaced with acid and alkali resistant gloves. 3. Oil-resistant gloves are made of materials such as nitrile butadiene rubber, chloroprene, or polyurethane. They are used to protect the skin of the hands from being stimulated by oils and fats to cause various skin diseases such as acute dermatitis, acne, and folliculitis , Dry skin, chapped, pigmentation and nail changes. 4. Welder gloves are personal protective equipment that protects the hands from high temperature, molten metal and sparks during welding. It is made of cow, pig tamarind leather or two-layer leather, and is divided into two-finger type, three-finger type and five-finger type according to different finger types. Welder gloves have strict appearance requirements. The first-class product requires uniform and thin leather body, fullness, softness and elasticity. The leather surface is fine, uniform, firm, consistent in color, and non-greasy. Second-class product: The leather body lacks full elasticity, the leather surface is thick, and the color is slightly shaded. 5. Anti-vibration gloves are used for personal protective equipment to prevent vibration-induced occupational disease “white finger syndrome” caused by vibration when in contact with vibration, such as handheld vibration tools (such as chain saws, rock drills, etc.) used in forestry, mining, construction, transportation and other departments . The structure of anti-vibration gloves is mainly to add a certain thickness of foam plastic, latex and air interlayer on the palm surface to absorb vibration. The thicker the pad, the more air it contains, and the better the damping effect. But when the palm and finger surface are too thick, it is easy to affect the operation. 6. Fire-retardant and flame-retardant gloves Traditional fire-retardant and flame-retardant gloves are made of asbestos materials, which are divided into two-finger and five-finger types, and are available in large, medium and small sizes. Because asbestos fibers are irritating to human skin, they are rarely used. At present, flame-retardant canvas or other flame-retardant fabrics are generally used to make fire-resistant flame-retardant gloves, which are suitable for smelting furnace pre-workers or other furnace types. 7. The anti-static gloves are composed of conductive fabric. The other is a long fiber elastic acrylic braided glove, and then the polyurethane resin is applied to the palm part, or the polyurethane resin is applied to the fingertip part or the surface of the glove is coated with polyethylene. Gloves containing conductive fibers quickly dissipate the static electricity accumulated on the hands. Gloves coated with polyurethane or polyethylene are mainly not prone to dust and static electricity. These products are mainly used for weak current, assembly of precision instruments, product inspection, electronics industry, printing, inspection work of various research institutions, etc. Eight, clean gloves Made from natural rubber, it can prevent the discharge of human fingertips during the production process. It can prevent the static electricity of the human body from damaging the product during the production process. The product is protected from the pollution and influence of finger residues, oil stains, dust and sweat during the production process, and the product is effectively protected. At present, most clean rooms use PVC gloves.

Responsible for shutting down the ventilator for severely ill patients. ICU nurse witnesses patients struggling to death: so painful

The scourge of New Coronary Pneumonia spreads all over the world. Medical equipment in various countries is seriously inadequate. Taking the ventilator as an example, most patients are given priority to young patients or those with high survival probability.

In the United Kingdom, the head nurse Juanita Nittla of the Intensive Treatment Department of Royal Liberty Hospital in London said that due to the limited number of ventilators, the hospital needs to be based on the patient’s age, health condition, viral response, and chance of cure To decide whether it is necessary to discontinue treatment. As for those patients whose condition has not improved for a long time, or patients with severe conditions, the hospital will remove the ventilator for them.

As the head nurse, one of Juanita ’s responsibilities is to remove the ventilator by hand for patients whose condition has not improved. In an interview with BBC Media, she revealed that she often became the medical nurse responsible for shutting down. Every time she faced this situation, she felt very struggling.

She said, “Turning off the patient’s breathing mechanism is one of my jobs, which is undoubtedly painful. Sometimes I even feel that I need to be responsible for the death of another person.”

Just about 2 weeks ago, Anita Hu received a notice instructing her to turn off the ventilator for a confirmed nurse in her 50s. Because the patient was in an 8-person room, she first pulled the curtains off and then turned off all the alarms to avoid disturbing others.

Juanita put the phone in her ear as the patient asked, so that she could talk to her daughter before she died, and then began to remove the ventilator for her. She said, “I looked at the flashing lights, the heart rate monitor on the instrument display device gradually to zero, the frequency becomes a horizontal line. I stood beside her, clasped her hands real, until she died.”

The name The infected nurse passed away safely within 5 minutes. Juanita then picked up the phone and told her daughter “Everything is over.”

To continue to watch the patient leave the world alone, Juanita admits that she is very sad, especially when she witnesses the patient struggling and breathing desperately, it will make her emotions very depressed.

Since the outbreak, the number of admissions has been rising, and ICU beds have almost doubled after nearly doubling. In the past, nurses would take care of patients one by one, but currently one person takes care of 3 or even 6 patients. The situation is really worrying. In addition, there are symptoms of medical treatments, which are suspected of being infected, and further combat morale.

As the head nurse, Juanita has to face countless life-and-departures every day. She has long suffered from insomnia and has nightmares more often: “This (the number of deaths) is daunting. I worry about getting sick, but everyone is equally afraid. “

80 countries and regions restrict the export of masks or other medical materials

The World Trade Organization (WTO) issued a report on Thursday stating that since the outbreak of the New Coronary Pneumonia Epidemic in the world, 80 countries and regions have banned or restricted the export of masks, protective equipment, gloves or other related products used to fight the epidemic. This has led to a shortage of such goods.

The WTO pointed out that 72 member countries and 8 non-member countries have implemented such export bans, but only 13 member countries have notified the WTO in accordance with the regulations. Lack of transparency and international non-cooperation have greatly reduced efforts to prevent the spread of the virus. The report said: “Under extraordinary circumstances, it is understandable to prohibit or restrict the export of certain goods, but under these circumstances, countries are reluctant to cooperate with each other, bringing various risks, which has caused some countries and regions that are highly dependent on imports to have medical treatment. Material supply is cut off. Existing medical material supply chains are intervened, and countries and regions that are in urgent need of medical materials are unable to obtain supplies. “The

current WTO regulations generally prohibit member countries from imposing export bans or restrictions, but there are some exceptions. of. The regulations allow member countries to implement temporary measures to restrict exports in emergency situations, such as an emergency shortage of food or other essential materials from the exporting party. According to the WTO, after the spread of the epidemic around the world, many countries and regions have implemented travel restrictions. In addition to reducing the flow of people, it has also caused a decline in the flow of goods. Together with the ban on export of goods, it has made it more difficult for governments of some countries and regions to adjust their procurement decisions And looking for new suppliers.

Approximately 26 million unemployed in 10 major cities across the US

The U.S. economy has been hit hard by the New Coronary Pneumonia epidemic. According to the latest local data, the number of unemployed nationwide has reached its highest level since the Great Depression in the 1930s. Currently, one out of six Americans is unemployed. On Thursday night, the House of Representatives voted to pass another bailout plan worth nearly $ 500 billion to provide financial aid to businesses and hospitals in financial trouble. The leaders of the EU member states also saved the economy on the same day by establishing an emergency fund of 1 trillion euros.

The federal government announced that 4.4 million people applied for unemployment benefits last week. Together, the top ten cities in the United States have some 26 million people who have applied for unemployment benefits in the past five weeks. As the epidemic is still not over, I am afraid that the economy will deteriorate and may further increase the unemployment rate. The House of Representatives overwhelmingly passed a new bill stimulating the economy worth 481 billion US dollars with 388 votes to 5 votes. The bill was passed smoothly in the Senate earlier, of which $ 75 billion was allocated to hospitals across the country; $ 25 billion was used to expand virus testing; and another $ 60 billion was for disaster recovery loans and grants.

Lawmakers who entered the meeting on Thursday all took adequate protective measures, put on masks and sat in groups, and kept as far away as possible during the debate. Halfway through the meeting, all members of the parliament must leave and be cleaned by the cleaning workers. Since the outbreak of the epidemic, President Trump ’s government has launched several rounds of economic stimulus plans, which are expected to push the federal government ’s budget deficit to a new high. Business people and economists say that when the epidemic is still grim and consumers are not confident enough to spend money outside, it is useless to approve the reopening of stores or restaurants.

On the other hand, the leaders of the EU member states held a video conference on Thursday and agreed to issue 540 billion euros to implement various economic assistance projects through the existing mechanism from June 1. They also agreed to establish an emergency fund worth 100 billion Euros to promote economic recovery after the epidemic.

French President Macron said there are still differences among countries on how to use this fund to make payments in the form of loans or grants. In Italy, which was hit hard by the epidemic, Prime Minister Conte urged partner countries, especially the richer Nordic countries, to be more united. European Central Bank President Lagarde told leaders of all countries that the epidemic will reduce the overall economic output of the Euro zone by between 5% and 15%.

Trudeau said that the military will lend a helping hand so that the two provinces can control the situation. But he added: “This is not a long-term solution. In Canada we should not send soldiers to take care of the elderly. I hope we can find a solution in the next few weeks or months. I think we must change the system and we will do it. At this moment, we will concentrate on protecting those who live in these facilities. “He also said:” We must do better. We have not taken good care of our parents, our grandparents, our elders are construction The great generation of this country, we must take good care of them. “

There are more than 42,000 confirmed cases and more than 2,200 deaths across Canada. In addition to Ontario and Quebec, other provinces such as Alberta, British Columbia and Nova Scotia in the east have deaths. During this period, most nursing homes and other homes forbid the visit of relatives. Health Minister Hajdu said: “We cannot isolate the elders forever.”
