Why is Digital Thermometer Better than Mercury Thermometer?

The mercury thermometer has been used for temperature measurement in our life quite a historic time. With technology development, a digital thermometer is taking over the mercury thermometer today. How come the digital thermometer is better than the mercury thermometer? Here we come up with three reasons to analyze.

 

1. Digital thermometer is faster on temperature measurement result providing

The digital thermometer gauges our body temperature by using electronic circuits. When the probe is heated by our body, it energizes the circuits with electric power and strengthens the amperage. The higher our body temperature is, the more powerful the electric flow is, and the stronger the amperage is. When the amperage is switched into data and shows on the thermometer screen, we can read the results immediately. The whole process is very fast in only 15-20 seconds. It works in the same theory as IR temperature gun. On the other hand, while, the mercury thermometer has to be 10-15 minutes so that we can see the results on the calibration tube.

2. Digital thermometer is more accurate for temperature measurement

Furthermore, digital thermometers are more accurate on body temperature than the mercury thermometers. The accuracy of a digital thermometer could be 0.1 ℃ with 0.01 ℃ errors. There is a thermocouple sensor installed in the probe of the digital thermometer. It is highly sensitive to temperature and will calculate it with accurate data on the screen. As to the mercury thermometer, whose operational principle is mercury expanding under heat, the accuracy is not as good as digital thermometers.   

3. Digital thermometer is safer for use on house living 

Since we would have to take our body temperature frequently at home these days, the digital thermometer is the best device because it is safe for usage. The mercury thermometer is made of glass and mercury. As we know, it is fragile. Moreover, mercury is a toxic chemical, which will contaminate human bodies after released. It is not easy to clean up if the thermometer is damaged and mercury splashes. The digital thermometer is made of hard plastic, PET material, and rubber. Same as the infrared thermometer, it is safe for our bodies. What’s more, it is not easy to break.   

 

From the three reasons above we can see that digital thermometer is better than a mercury thermometer on faster and more accurate measurement results providing, safer for use in our life. Taking our body temperature at home every day is necessary because it is a good way to avoid Covid-19 from spreading. All in all, you may leave your comments if you have any opinion about the analysis above.

3 Ways to Make DIY Face Mask at Home

A face mask is good equipment to keep us from pollutions and harmful particles in the air. Since the Covid-19 outbreak, we are more and more concerned about our respiratory health. Here we would like to teach you three ways on how to make DIY face masks with simple materials. With these methods, we can make our beautiful unique face mask at home.   

 

1. How to make scarf face mask

Our scarf and bandana are great materials to make face masks. Firstly, pick a clean smooth scarf to tile on the table. Fold it into layers from up-down and bottom-top, make it as a strap. For better filtering effect sake, we’d better embed a cotton yarn layer inside. Remember the strap height should be covered from your nose to your chin. Place two rubber bands on each side and fold the two sides to the middle. Tuck on end to the other and smooth the surface. Now a scarf face mask is completed. Try it on and make it comfortable on your face.

2. How to make a T-shirt face mask

We can make face masks with our T-shirts. Our wear out T-shirt, make sure no holes on it, or new purchased T-shirt if you don’t mind cutting it up, is great for making face masks. Choose the 100% cotton one would be better because it is more effective for filtering. Cut the bottom of the T-shirt in the height of the distance from your nose to your chin. Normally, the distance would be 7 to 8 inches for adults and 4 to 6 inches for children. Cut it into 6 to 7 inches and left two strings on the top and the bottom left the rest part enough for the coverage of your face. Cut the two strings so that they can be knot around your head and neck. Sew a filtering layer under the face mask. A T-shirt face mask is completed. It’s very simple.

3. How to make cloth face mask

If you want to make your favorite style face mask in beautiful colors and patterns, this method would be delightful to you. On doing this we will need a sewing machine. Choose a piece of clean cloth with the colors and patterns you like, and fold it into two or four layers. Cut the cloth into the style shape you like, here we take the surgical mask style as an example. We cut the cloth in 10*6 inches cube, smooth it on the table with the pattern side on the bottom and the material side towards you. Same as we mentioned, we embed a filtering layer in the middle. Fold the top and bottom side in about 0.25 inch and stitch with the sewing machine. Hem along in 0.5 inches and stitch the left and right sides, make two long strings on each side for knotting. A new cloth mask is completed.    

 

These are the three simple methods for making DIY face masks at home. One thing we have to remember is that DIY face masks made ourselves are not meet the CDC standards, which requires our frequent changing, washing, and disinfection. Besides, we may also go online shops for KN95 face mask or disposable surgical mask. No matter what, we should always remember to wear a face mask outdoors. Personal health should be always in the first place.

What is PPE and What Do We Need to Know About it?

PPE stands for Personal Protective Equipment. Since the new virus of COVID-19 outbreak, PPE is badly in need of many countries around the world. We can see from the live news reporting that medical workers are all equipped well for nursing the patients in the hospital. We should send our sincere respect to them. Maybe some of us wonder what define as PPE and what do we have to notice about PPE usage. Here we would like to discuss it in three aspects below.  

 

1. What is Personal Protective Equipment?

Generally, the personal protective equipment could be any safeguard for the protection of our exposed body parts like mouth, eyes, head, hands, or feet. Commonly referred to as "PPE", these equipment are designed and manufactured to minimize the injuries and illness resulted from chemical, physical, electrical, mechanical, or other workplace hazards to our body. All personal protective equipment should be designed and manufactured based on safety and reliable sake. It should properly fit our body in the first place. Besides, it can make the difference between being safely covered or dangerously exposed.

 

2. How to put on and take off personal protective equipment?

Before we are about to put on our personal equipment, we need to cleanse our hands. Pull your hair back or tie it up if it is too long, then you may take steps on donning the equipment.

Apron/Isolation Gown – Make sure it is full coverage around your body, from neck to knees. Pullover the head and fasten at the back. You may need help from your fellows if you cannot do it yourself. 

Surgical Mask/KN95 Respirator – Put it on and cover it over your mouth and nose. Secure the ties or elastic bands in the middle of the head and neck. Fit flexible band to Nose Bridge. Fit snug to face and below the chin. Readjust it to a comfortable position.

Eye Protective Goggles & Face Shield – Just put it on and cover on your eyes and face, adjust it to a comfortable position.

Surgical Gloves – Select a suitable size with your hands. Extend to cover to your wrist. Use free hands washing sanitizer to make your hands smooth for easy wearing.

The order for removing PPE is Gloves, Apron or Gown, Eye Protection, Surgical Mask. As to some disposable equipment like the surgical masks, medical caps, or gloves, we should discard it in a certain place and never throw it around. Remember to wash your hands after taking off the equipment.

 

3. Can Personal Protective Equipment Reused or Shared?

It is not recommendable to reuse the medical protective equipment. PPE needs to be disinfected at a high level if necessary to reuse. Since the medical supplies and protective equipment become in shortage, some of the PPE would need to be reused. This includes N95 respirator, eyes protective goggles, face shield, or surgical gloves. Do not share personal protective equipment with others, because the hygiene for medical devices is important.

 

These are the aspects of PPE we would like to share with you. No matter where we go and what we do, we should remember to equip ourselves for the protection of viruses outdoors. We hope our description above could be helpful if you are planning your future career to be a medical worker. Anyway, you should also visit our site for some simple personal protective equipment like KN95 mask, face shield, eyes protective goggles, etc. You may also contact us via email if you need our medical equipment. 

8 Terms You Need to Know About Covid-19

The coronavirus has become the global pandemic and it has brought great effects to our lifetimes. We need to stay healthy and fight with the virus, on the other hand, we need to learn some knowledge about medical and antivirus. There are some terminologies we need to learn about the COVID-19 so that we may better understanding the new reports. Here we quoted some terms which have been updated to the dictionary. Let’s check them out.

 

Coronavirus: A new kind of virus typically spreads between animals and humans, which causes respiratory illness. Coronavirus is a family of viruses that includes SARS and MERS. The name of “corona”, in Latin for crown, refers to the shape of the virus when observed under the microscope. Coronavirus has become the most lethal virus in the world in 2020.

COVID-19: COVID-19 stands for novel coronavirus disease 2019, which refers to the year of its initial detection. COVID-19 is the illness related to the current pandemic; the illness is caused by the virus SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2).

Asymptomatic: An asymptomatic person shows no symptoms of the disease. The symptoms of the COVID-19 infected patients are fever, dry cough, and sore throat, shortness of breath and body aches, among other less common symptoms. This doesn’t mean an asymptomatic person has no potential infection, but it is not recommended that individuals get tested unless they show symptoms of infection. For the medical equipment standard of the present time, most tests will not be accurate unless symptoms are present. False negatives will be risky for tested persons.   

Confirmed positive case: A confirmed positive case is someone who is confirmed to be Covide-19 positive from the Centers for Disease Control and Prevention (CDC), which needs to be distinguished from a presumptive positive case.

Contact tracing: To identify and monitor one person or a group who may have come into contact with an infectious person. In the period of Covid-19 spread, Contact tracing is usually executed to monitor and observe persons who may have contact with the infectious person, which requires self-quarantine in order to control the spread of disease.

Incubation period: A period of time from an individual person first infect the virus to the appearance of symptoms. It is unknown how serious the contagion will be before a person’s symptoms arise. The length of the incubation period is different from person to person.

PPE: Short for personal protective equipment, something like the face mask, antivirus goggles, face protective shield, antivirus suit, gloves and so on. The PPE is designed and manufactured as the safeguard against the harmful viruses, infectious diseases or corrosive chemicals. It is specially designed for the protection of our body parts which exposed in our normal clothing, such as nose, mouth, eyes, and feet. In the war of fighting Covid-19, PPE is necessary for everyone.

Self-quarantine: the act of refraining from any contact with other individuals for a period of time—in the case of COVID-19, two weeks—to observe whether any symptoms of the disease will arise after potential exposure.

 

These terms are mostly showed on the reported news we received every day. We hope the definitions above would be helpful to us on better understanding Covid-19. Besides, you may visit our website on some useful protective equipment, such as KN95 mask, face protective shield, antivirus goggles and so on. You may contact us if you need any items of our medical supplies, or leave your comments below if you have some new terms and knowledge about Covid-19 to share. We appreciate that.

 

Must We Wear Face Shield and Goggles Outside?

The COVID-19 has been the most fatal virus in the world. The infection rate is raising since its spread in Europe and America. We have taken antivirus actions to protect ourselves by wearing masks, using hand sanitizer and isolating ourselves at home, but that seems not enough to us. Most people think there should be a defensive barrier we need to protect our eyes and faces to the surrounding air, especially in some public places or workplaces. Face shields and goggles are necessary for protection. Is that necessary for us? Must we equip ourselves outside the door? Let’s see the analysis below.    

 

1. How does the COVID-19 spread?

According to the earliest broadcast in China, the COVID-19 pathogen was found on animals. How come it spreads on humans? It reminds a mystery. This virus can be transmitted from human to human in any places. When someone is affected, coughing or sneezing may be a transmission of COVID-19 virus. People stand within about 6 feet from the affected person may catch the virus in respiratory droplets. Although wearing face mask has greatly decrease the infection rate to a person, it is still possible that one get COVID-19 infected by object surface touching. When we touch our eyes, nose or mouth with unwashed hands, it is a way for virus transmission. Wash hands with sanitizer soap could eliminate more than 90% virus on our hands, furthermore, protecting our faces from harmful particles in the air is more important.  

2. How to stop the virus from spreading?

There are mainly two ways to stop the virus from spreading, one is eliminated the source of the virus and the other is cut off the transmitted route of the virus. We wash our hands with sanitizer soap and spay with ethyl alcohol for elimination, that’s an effective way to kill COVID-19 virus from the original source. Besides, we take our body temperature and go to the hospital immediately once we have a fever. This is helpful to eliminate the virus from spreading from the source. We isolated ourselves, no gathering, no parties, and public activities. This is unacceptable to most of us but it is a good way to cut off the transmission route of the virus. Furthermore, wearing face masks outdoors is a way to stop the virus from transmitted from person to person. If you are working in some special places like hospitals, chemical place or laboratory, a face shield would be necessary equipment for you.     

3. Must we wear face shield & goggles outside?  

As we mentioned before, the virus can be transmitted via body fluids as splashes, spray and spatter from infected persons. A medical face mask can filter 90% harmful particles in the air, but it only works for respired protection. On the other hand, face shields and goggles are generally not used alone, which requires in conjunction with other protective equipment and are therefore classified as adjunctive personal protective equipment. If you work in a hospital, or some special place like food processing, chemical industrial or laboratory, then this equipment is necessary for you. Good face shield or closed goggles are made of strong, durable and transparent hard plastic material that provide us all face protection. If you are going to a crowded public place, such as shopping mall, metro stations or markets, waring face mask, face shield or goggles is advisable to you.

 

All in consumption, it necessary to wear a face shield or goggle together with face mask if you are in some special professions. We also recommend you equip yourself if you are going out to some public place since the COVID-19 spread this time. Finally, we suggest you go to our shop for antivirus supplies such as KN95 mask, closed goggles, face shield, etc. You may contact us or email us if you need any medical supply.
