exhalation valve for easy breath

EasyBreath exhalation valve for ventilator.

There is a hug bug in "isinnova"'s design: a direct short circuit between its air inlet and air outlet. The carbon dioxide exhaled by the patient will remain near the mouth and nose, causing respiratory acidosis.

So I made such an exhalation valve to connect to the outlet of the ventilator.

I don't have the 3D parameters of EasyBreath, so I can't achieve strict sealing. I need to apply thick Vaseline before installation to ensure air sealing.

Although I don't believe that 3D printed mask can really be used clinically, I cannot tolerate such a bug. It must be fixed.
