Whether jogging wears a mask causes controversy

According to the European Times reported on the French news radio station (Franceinfo) website on the 16th, the outdoor mask order implemented in many parts of the country has created new problems for many runners; in fact, the World Health Organization (OMS) does not recommend Wear a mask because the mask will hinder smooth breathing and will accelerate the spread of disease once it gets wet.

The doctor said “no scientific basis”

On the streets of Paris, many runners had to obey orders. The mask on the face of Pierre, who is jogging by the Seine, is close to his nose and mouth, “I am running with a mask for the first time.”

He said, “It’s okay, better than I thought. The weather is not too hot, otherwise, it will be really uncomfortable… But there are not many people on the river bank now, and it is useless to wear it, but at night people will A lot”.

Not far away, Thibaud, another runner, didn’t wear a mask. He didn’t seem to know that the banks of the Seine River were within the prescribed range. “Is there a mask to wear here? I didn’t see it. I tried to wear it, but I couldn’t help it. Breathe, the whole mask is wet… so I won’t run with a mask… If other runners don’t wear it, I don’t see the meaning of coercion.”

According to the Paris government announcement, pedestrians in the relevant neighborhoods must wear masks, “including when doing sports.” However, the doctor Jean-Francois Toussaint felt that this was unnecessary. He even thought that the mandatory wearing of masks outdoors was “unscientific” and “wrong”. He said, “Swedes do not have such measures, but allow people to continue running to exercise.”

Fighting the motivation to exercise?

During the ban, many people joined the ranks of running to exercise. After the outbreak of the epidemic, some sporting goods stores did not decline in turnover but increased, but now they have to worry that the mask enforcement order will discourage people’s enthusiasm for exercise and may cause them to lose these new customers.

Nicolas Gardon, editor-in-chief of Jogging International magazine, estimates that those who pick up the fun of jogging during a foot-free period are not yet addicted and may lose their patience.

But he believes that long-term runners will insist on running, and will insist on not wearing masks. He said, “There are two types of Paris runners that I have met. One is that they insist on running without a mask in a prescribed block. Their attitude is’if you catch it, you will pay a fine.’ The other is that the block is usually run. Within the specified range, simply change to a block where it is not mandatory to wear a mask and continue running.”

Which is more accurate, mercury thermometer or forehead thermometer?

Fever is one of the most common clinical symptoms. How to judge whether the fever is the most common method to take body temperature. But many people have improper measurement methods and are easy to be inaccurate. What should we do?

1 Choose the right time

To eliminate the influence of body temperature fluctuations, choose a suitable time to measure.

The standard for clinical fever is a body temperature of 37.3°C or higher. However, strenuous exercise, after meals, emotional stress, and excessive indoor temperature can all cause body temperature to rise, so it is best to take your body temperature in a quiet state in the morning and evening.

It is recommended not to eat, drink, exercise vigorously, and compress hot or cold compresses before taking the temperature.

2 Use thermometers to be standardized

The use of thermometers should be standardized. Different thermometers have different temperature measurement methods, and the results may have errors. Common mercury thermometers, infrared thermometers and electronic clinical thermometers should be selected according to different occasions.

Mercury thermometers belong to the medical category, and mercury thermometers are used clinically to measure body temperature; electronic thermometers are very convenient and suitable for home use, but need to be checked regularly; infrared thermometers have the fastest temperature measurement and are suitable for continuous temperature measurement of multiple people, but not suitable For family or personal use, it also requires regular proofreading.

3 Mercury thermometer is more accurate

To measure body temperature at home, it is recommended to measure the underarm body temperature with a mercury thermometer, which is the most accurate; the underarm body temperature above 37.3℃ requires attention, and the oral temperature above 37.1℃ requires attention.

Self-protection Guidelines For shopping during Coronavirus

According to real-time statistics from Johns Hopkins University, as of April 14, the number of confirmed cases of coronavirus in the United States has reached 582,594, exceeding the 400,000 cases with the second-highest number of diagnoses in Spain.

Faced with such a raging virus, many people chose to quarantine at home. But for daily necessities, I had to go shopping. In order to prevent coronavirus infection during the shopping process, the following nine guidelines are worth learning.

coronavirus, people wear the mask

1. Wear a mask

Before going out for purchase, you must wear a mask. The environment of the supermarket is relatively closed. The general environment of the farmers market is also relatively poor. Wearing a mask is the best protective measure to prevent the spread of droplets. Wear the mask correctly and check the tightness of the mask before going out.

2. Enter the supermarket

Make a purchase list before shopping to make clear which items need to be purchased in order to shorten the shopping time. Wear a mask throughout, and keep at least one meter away from others.

3. When purchasing

It is best not to touch the goods directly with your hands, you can wear gloves or put the shopping bags in the supermarket on your hands. It is best to purchase all at once to reduce the frequency of shopping. Don’t stay after buying, go home immediately.

4. Meat area

At present, no formal meat and seafood products have been found to spread viruses and can be eaten with confidence. Do not buy poultry from unknown sources, and do not eat game.

5. Cash register

Consciously queue up, keep a certain distance from others, bring your own shopping bags, and minimize contact with public facilities.

6. On the way home

Try to choose walking, cycling or self-driving. When riding a shared bicycle, pay attention to wipe and disinfect. For example, when taking public transportation, you should separate and sit down to avoid touching the items in the car.

7. Elevator

People on the lower floors recommend taking the stairs and not touching the handrails. When touching the elevator buttons, they can be separated with paper towels, try not to communicate in the elevator.

8. At the door

Take off the mask, fold the mouth-nose contact face outwards, fold it twice, tie it with ear straps and put it in the trash.

9. After entering the door

Carry the dishes directly into the kitchen, don’t put them around.

Wash your hands immediately with running water and wipe your hands with 75% alcohol or 0.5% chlorine-containing disinfectant.

The door handle surface can be diluted with 1 to 100 of 84 disinfectant to wipe and disinfect. When necessary, the surface of shoes and shopping bags can be sprayed and disinfected with 75% alcohol.

Why 75% of alcohol sterilization is best, not 95% alcohol

Recently, for coronavirus, some experts pointed out that 75% of alcohol (ethanol) can effectively kill the virus, so everyone has snapped up medical alcohol for disinfection. Why is 75% alcohol effective for killing the virus? Would it be better to use 95% alcohol? What should be paid attention to in the process of using medical alcohol?

First, we must understand the type of alcohol, alcohol is divided into industrial alcohol and medical alcohol. At the time of purchase, the main components of alcohol can be viewed and distinguished. The main component of medical alcohol is ethanol, and the main component of industrial alcohol is methanol.

Industrial alcohol is the alcohol used in industry, also known as denatured alcohol, industrial fire wine. The methanol content is high. Due to different manufacturers, its proportion is not the same, generally more than 90%. It can be used in printing, electronics, hardware, spices, chemical synthesis, pharmaceutical synthesis, etc. It can also be used as a cleaning agent and solvent, but it cannot be used for human body disinfection. If industrial alcohol is used for skin disinfection, it may be partially absorbed by the skin, leading to poisoning.

Medical alcohol is a mixed solution of ethanol and water. Medical evidence shows that when the concentration of ethanol is 75%, the disinfection effect is the best. It can kill a variety of bacteria and viruses, and can also effectively kill new coronaviruses. Medical alcohol can be used for human body disinfection, the main purpose is disinfection and sterilization.

Different concentrations of medical alcohol have different effects.

  1. 25% ~ 50% of alcohol can be used for physical fever. Patients with high fever can wipe their body to achieve the purpose of cooling. Because wiping the skin with alcohol can dilate the blood vessels of the patient’s skin and increase the heat dissipation capacity of the skin, its volatility can also absorb and take away a lot of heat, so that the symptoms are relieved. But the alcohol concentration should not be too high, otherwise, it may irritate the skin and make the epidermis lose a lot of water.
  2. 40% to 50% alcohol can prevent bedsores. Prolonged pressure on the back, waist, and buttocks of long-term bedridden patients can cause bedsores. For example, pour a little 40% to 50% alcohol into the hands during the massage, and evenly massage the patient ’s compressed area to promote local blood circulation The purpose of the formation of bedsores.
  3. 70% to 75% alcohol can be used for sterilization and disinfection, including skin disinfection, medical device disinfection, and iodine deiodination. This refers to normal skin disinfection, not wound disinfection.
  4. 95% of alcohol is often used as a fuel for alcohol lamps and alcohol stoves by medical institutions. It is used to heat laboratory reagents or pharmaceutical preparations after ignition. It can also be used to temporarily sterilize small medical devices with its flame.

75% and 95% of medical alcohol are common in pharmacies. Is the higher the purity, the better the sterilization effect? Neither pure alcohol nor water is enough to denature the protein in the bacteria. Only when alcohol and water coexist, and at the same time relax the various attractive forces that maintain the geometric shape of the protein, the protein will lose its physiological activity. Therefore, only a certain concentration of alcohol solution can achieve good disinfection and sterilization purposes.

The 95% alcohol concentration is very high. An excessively high concentration of alcohol will form a protective film on the surface of the bacteria to prevent it from entering the bacteria and it is difficult to completely kill the bacteria. If the alcohol concentration is too low, although it can enter the bacteria, it cannot coagulate the protein in the body, nor can it completely kill the bacteria.

75% medical alcohol, because the water is mixed with alcohol, the concentration of alcohol becomes thinner. Dilute alcohol does not rush to solidify the protein on the surface of the bacteria but penetrates into the bacteria, and then solidifies the protein in the whole bacteria. So as to achieve the purpose of sterilization. When the alcohol concentration is 75%, its sterilization ability is the strongest.

Because alcohol is a flammable liquid, it is very inconvenient to carry. For personal travel, we recommend using 75% alcohol to disinfect wipes, which is very convenient.

What should be paid attention to when using alcohol?

Ethanol has strong volatility and is extremely flammable. When using alcohol, keep away from sources of ignition to prevent the ignition of alcohol and fire. Also, prevent burning and explosion caused by alcohol vapor. When spray disinfection is carried out in many places recently, alcohol vapor is easy to generate due to its strong volatility. Especially in closed spaces, such as rooms with closed doors and windows, alcohol vapor may accumulate and reach the explosion range. Burn or even explode.

The difference between the invasive and non-invasive ventilator

Up to now, more than 480,000 confirmed cases of coronavirus have been diagnosed worldwide, making it the most powerful virus since the 21st century.

Because coronavirus hits the human respiratory tract first, demand for ventilator products has skyrocketed.

A ventilator is a device that can replace, control or change a person’s normal physiological breathing, increase lung ventilation, improve respiratory function, reduce respiratory work consumption, and save heart reserve capacity. The difference between an invasive ventilator and a non-invasive ventilator is Which ones?

1. Whether the wound is different

For patients, tracheal intubation ventilation is invasive, and mask ventilation is noninvasive.

2. Do you need different oxygen sources?

An invasive ventilator requires an oxygen source to use, a non-invasive ventilator can be used without an oxygen source.

3. With or without built-in turbine

Most invasive ventilators do not have a built-in turbine, while all non-invasive ventilators have a built-in turbine.

4. The different scope of application

Although the invasive ventilator can be used with a non-invasive ventilator mask, a non-invasive ventilator can be used as an invasive ventilator after adding a platform valve. But neither can replace the other, and each has its own specific range of adaptation.

Now Novacciva can also receive ventilator enquiries, please contact us if you need.

Mask Trilogy: How Are Qualified Masks Produced?

Today, masks are closely related to the daily life of each of us, especially during the epidemic, masks have become a hot word in society.

Without a mask, people became infected after 15 seconds of close contact! The importance of wearing a mask is beyond doubt, so how exactly is a mask produced? Today, I will present the “Trilogy of Masks” to make it clear to everyone!

Producing 120 in one minute, analysis of the status of mask production in China

According to data, China has nearly half of the world ’s mask production capacity. From 2015 to 2019, the mask industry in mainland China has developed rapidly, with the output value growth rate remaining at more than 10%. Among them, in 2019, the output of masks in mainland China exceeded 5 billion, with an output value of 10.235 billion yuan, and medical masks that can be used for virus protection accounted for 54%. It is understood that the raw materials for the production of masks are mainly high-melt-fiber polypropylene, and the effectiveness of masks in isolating bacteria is directly related to its production process.

From the point of view of mask materials, polypropylene high-fusing non-woven special materials have become the best choice. The production of polypropylene products with a melt mass flow rate of 33-41g / min has reached the standard of non-woven polypropylene nonwovens. In terms of fiber application fields, polypropylene fiber special materials are used in non-woven fabrics, clothing fabrics, carpet yarns, medical surgical supplies, and civilian sanitary products. In terms of medical and health, non-woven fabrics made of polypropylene non-woven fabrics can be used in disposable surgical gowns, sheets, masks, covers, liquid absorption pads, etc. Non-woven masks are made of fiber There are two layers in the woven fabric, with an additional layer in the middle that is more than 99.999% filter-resistant spray-dissolved spray cloth that is welded by ultrasound. The nose of the non-woven mask is made of environmentally friendly plastic strips, without any metal. Breathable and comfortable.

From the perspective of the total output of non-woven fabrics, China’s non-woven fabrics (non-woven fabrics) increased exponentially in the early stages of the development of the industry. During the 20 years from 1978 to 1997, China’s annual output of non-woven fabrics increased nearly 100 times. Since entering the 21st century, China’s non-woven fabric output has maintained a growth trend. After the 2008 financial crisis, China’s non-woven fabric output has continued to increase year by year.

In 2018, China’s annual output of various non-woven fabrics reached 5.932 million tons, an increase of 196.31% over 2008. The average annual compound growth rate is 11.47%. In the field of application, the current application of nonwovens is focused on the penetration of high and new technologies and the use of new materials. It is widely used in construction, automotive, clothing, sanitary materials, aerospace, environmental protection, and other industries, especially in the sanitary materials market.

How to distinguish between genuine and fake masks in the face of coronavirus?

The outbreak of a new coronavirus has affected many people’s lives. People were unable to travel because of the illness. So some manufacturers will also suffer significant losses because of it. However, in order to prevent this virus, the mask factory has been working overtime. There are already many types of masks on the market. So when we choose a mask. How should I choose?

1. Source

The first is to look at the source of the mask. For example, does the manufacturer of masks have a relevant qualified license and whether all his raw materials are safe?

2. Packaging

The second is to look at the packaging of the mask. It should be noted that the packaging of the mask is not complete. Is the production of this product in compliance with the standard and is there any standard number?

safety masks
3ply safety mask


The third is to see the printing of masks. For example, is it clear whether the logo and font printing on the package is clear. And some genuine masks will have anti-counterfeiting signs. These are also an important criterion for authenticity verification.


The fourth is to look at the logo. For example, are masks under the warranty? All his production dates and manufacturers are regular.

5. Products

The fifth is to look at the product itself. Whether the mask has a filter layer, whether there are some stains or shreds, and whether there is an odor.

Is it really useful to wear an earloop face mask when the flu is raging?

How can we effectively isolate the flu when the flu is raging? Many people will wear earloop face masks, but can earloop face masks really isolate the flu?

wear earloop disposable face mask

As a contagious virus, the flu involves all people, and pregnant people, children, the elderly, and other people with poor immunity are highly susceptible. The flu is mainly spread by droplets such as sneezing and coughing, and can also be transmitted directly or indirectly through mucous membranes such as the mouth, nose, and eyes. Therefore, the general earloop face mask does not have a barrier effect on the spread of influenza virus.

Some doctors pointed out that masks have a better preventive effect on bacteria, and the effect of preventing viral diseases is worse, but it still has a certain effect. We really want to completely prevent the spread of air and droplets, need N95 earloop face mask, N95 earloop face mask is more expensive, mainly used for personal occupational protection of medical staff. In addition, although the impact of the flu virus is large, in the face of the flu, while raising vigilance, it is also necessary to avoid excessive panic, to improve self-care awareness and prevent it in place. The flu shot is the most cost-effective preventive measure.

In the face of the flu, we must adhere to a healthy lifestyle and good hygiene habits, wash hands and exercise more, and go to places where people are crowded and airy. Once you have flu symptoms, you should stop going to school or go to work and seek medical advice in time to avoid transmission to others.
