DMask for Covid-19 Patient, Healthcare Worker (HCW) PAPR Supplied Air Respirators

Charlotte Valve by the Italians are brilliant!

We have 3d printed some at TeaMa with multiple heads for multiple users. Here's a breakdown:
1. Patient - objective is to provide ventilation and prevent the spread of Covid-19 positive patients. Good thing is that the Decathlon EasyBreath Snorkelling Mask comes in 3 sizes : Junior, Women and Men. We are doing trials in several hospitals (Covid-17 screening hospitals) across Malaysia.

2. Healthcare Worker (HCW) - Supplied Air Respirator, though with a limited field of view, it sure beats conventional masks that start at USD$100-2,000!

3. HCW - Powered Air Purifying Respirator (PAPR) for Ambulance Services. This has always been the direction we are heading with the Reverse Pressure Pumping!

These are additional connectors for the DMask, that interfaces with the Charlotte Valve. The Charlotte Valve has undergone a thickness enhancement, after rigorous our testing.

This multi-purpose F-adapter is well suited for Malaysian Hospitals. Its flexibility creates a dual purpose function; where the inner diameter is used for one thing (i.e., Nebuliser) and the outer diameter, can be used to connect to existing Hospital tubings.
