COVID-19 is a respiratory infection. Ingestion of the virus from the nose and mouth causes symptoms such as pneumonia.
Conversations during meals are at high risk of infection.
However, you can get infected without talking face-to-face.
The protection with a surgical mask or face shield is not perfect.
When a high concentration of virus is scattered, there is a possibility that it will enter through the gaps in the protective equipment.
Therefore, we developed a face shield to protect medical personnel.
It is a mask that can be fitted with a particulate filter.
Hold the rubber band with both hands and hang the bottom edge of the mask on the wearer's chin.
Put on the rubber band by pulling it down on the back of your head like wearing a hat.
Align the full face respirator.
Since the mouth and nose breathing parts are separate rooms inside the mask, fit it so that it covers the nose and mouth nicely.
Also, if the outer circumference does not fit the face exactly, it may cause air leakage and suck unnecessary air.
Pull the left and right lower rubber bands to make the mask fit your face tightly.
The rubber band is a consumable item.
The air supply connector on the top of the full face respirator should be brought into close contact with the O-ring (rubber packing), then the latch should be hooked and the lever should be pulled down until it snaps into place.
Visually check the close contact with the O-ring.
You can optionally install a HEPA filter.
Insert it into the connector with a slight rotation and check that it does not get stuck.
The base of this full face respirator is a snorkel mask (scuba gear).
It is designed to have high adhesion so that water does not enter.
The air is taken in from above the surface of the water, and the air is
Applying that system, the supply air passes through the filter.
The connector size is adjusted so that various HEPA filters used as artificial noses and particulate filters can be installed.
Generally, only one ventilation port is required, but we also have two types for those who may move violently.
