The use of 3D printed valves to enable the use of ventilators for multiple patients

Current status

Open source designs for the valves were utilized from the following resource:

The first of these splitter valves has been delivered to Manipal Hospital and tested there. The above link enables anybody with a 3D printer to utilize these designs to print this. The video below shows the splitter being used with simulation lungs at Manipal Hospital.
