The United States is currently the country with the highest number of Covid-19 patients in the world, with more than 104,000 cases of the 617,000 cases globally. In the state of emergency that they have declared, businesses and academic institutions in the US have constantly joined hands to find all measures to help the federal government to control the disease.

One of the current essential needs focuses on personal safety tools and devices (PPE). And a team at New York University recently developed and launched an effective mask design that could prevent the corona virus droplets from spreading by Covid-19 patients.

What is even better is that they shared this design for free, so that any business, anywhere in the world can produce it in large quantities. A New York University guide can also help you create your own face shields at home.

Their blueprint specifies each material you need, their size, the steps to cut each part and use.

As one of the open source projects supporting the production of personal protective equipment, New York University has targeted a simple, cheap, and scalable method to Create mask masks.

This direction is different from some other projects that are based on 3D printing technology. Theoretically, when someone designs a mask print and shares it for free on the internet, any hospital, company or individual that owns a 3D printer can print it. them to use according to your needs.

However, 3D printing depends very much on the source of ink materials that each person has. The printing process is also very time-consuming – a mask may take half an hour to complete.

In contrast, New York University’s approach only requires basic materials, including two pieces of clear, flexible plastic and elastic bands. A mask can be assembled in less than a minute, as long as you have purchased enough materials.

The team also provided the appropriate design files to load into laser or CNC cutting machines so that the needed units could produce in large quantities. For individuals and consumers, you can also use this pattern to cut yourself a mask shield, which only requires a pair of scissors.

The following is a guide of New York University:


Shield part: 1 transparent PET or polycarbonate sheet (0.007 to 0.01 inch thick) size: 12.5 x 10.25 inches (equivalent to 31.75×26 cm)

Part sling: plastic or similar materials 10.75 1x inch size (equivalent 2,54×27,3 cm)

Strap part: elastic band 3/8 or ½ inch (equivalent to 9.5 mm or 12.7 mm), 16 inches long (equivalent to 40.64 cm).

Face shields are an important device for frontline doctors, nurses, and paramedics when they come into contact with Covid-19 patients. Essentially, they are a large, transparent piece of plastic that covers the wearer’s entire face.

Face shields must be used in conjunction with a medical mask or N95 respirator in order to protect healthcare personnel from virus-containing droplets of a Covid-19 infected patient.

Droplets containing viruses are droplets of mucus in the airways of an infected person, which can be spread through the nose, mouth, and even the eyes when they cough, sneeze, talk and … breathe.

Research shows that when an infected person sneezes, they can spread into the air 40,000 splashes. These droplets can travel up to 6 m at a speed of 50 m / s.

When a person coughs or talks for 5 minutes, they can spread 3,000 drops of shot. Cough drops when coughing can travel over a range of 2 m at a speed of 10 m / s. And even when an infected person breathes, they can spread droplets over a range of 1 m at a velocity of 1m / s.

If unprotected, a health worker can breathe in his or her airways more than 30,000 virus particles in a single breath after the patient coughs.

Currently New York University has distributed more than 100 masks to doctors in Mount Sinai Hospital System. It has been successfully tested and confirmed with basic clinical function. The team said they can produce about 50,000 screens each week, starting in late March, once the material is supplied by the partner.

They also strongly welcome any company, organization or individual to copy this design to create more products to meet the needs of the health system and the individuals who need it. New York University also expressed its desire to cooperate with companies that can help them increase their production scale even bigger.

Many other companies in the US and around the world are also working to address the general shortage of medical devices and personal protection in the Covid-19 epidemic, including free production and sharing of designs. ventilator or breathing apparatus.

These are all great examples of how we can work together to work towards a common interest in the crisis caused by the Covid-19 epidemic.
