Henan enterprises began to develop new isolation caps. What hard-core operations are there to defend against the epidemic?

The protective cap is fully protected and fastened with an elastic band? The closed isolation cap uses an exhaust and ventilation system driven by a small motor? Well, it's really hard-core, comparable to the enterprise that blows fans with fans.

when the company developed a new type of protective cap, I thought it was a high-tech product. Later, it turned out to be a DIY similar to manual Geng, but the biggest difference is that it can be mass-produced and put on the market, instead of being unable to make several pieces by one person like manual Geng.

First of all, we all know that medical staff need to take protective measures when they come into contact with patients in COVID-19. However, after using the existing protective facilities for one day, it will cause some troubles to the body. For example, doctors wear less goggles and are easily infected by droplets sprayed by patients when they cough. For example, a nurse wears protective clothing for a day, and when she takes it off, her skin is deformed and scarred?

So the first idea of this isolation cap is to completely cover the head and isolate the outside world. To this end, adopt? Totally enclosed? The design, there is no hole in the head, to avoid close contact, eyes, nose and mouth and other parts will come into contact with droplets.

In order to strengthen this effect, there is an elastic band around the neck of the isolation cap. Although it is elastic, it can be tightened and contracted, so that the bottom of the isolation cap can be tightly stitched without contact with the outside world.

Secondly, in order to prevent medical staff from being trapped in the isolation cap when using it, the isolation cap also has a conduit for the other end of the isolation cap to discharge air. This exhaust device mainly relies on a small motor and a filter layer made of meltblown cloth and other materials.

In this way, dust, viruses, etc. outside can be isolated. When inhaling, these substances will be filtered out first, and then fresh oxygen will be supplied to the isolation cap.

To some extent, it can really help frontline workers who are short of masks and medical protection equipment. But if there is any hard-core black technology, there is actually no such thing. These things are sold on Taobao, but they are only creatively transformed? Even a little suspected of plagiarism?
