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

By

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!

Step 1: Additional Connectors & Universal Adapter for Malaysia Using the DMask

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.

Step 2: Colour Coded Adapters to the Charlotte Valve

GRAY = Main - Charlotte Valve - v1r2 - Increase wall thickness

RED = Outgoing Center Adapter from Charlotte Valve to Air Filter - V1R2

GOLD = Incoming Big O2 F-Adapter to Charlotte Valve - V3R1 (V3R2 - with tree support)

GREEN = Incoming Small Tube Adapter to Big O2 F-Connector - V3R1
