A new and improved splitter for ventilators

This simple-looking device is a real life saver.

It’s a 3D-printed ventilator connector, dubbed the “Cerebrus Multivent.” The device, developed and printed at TTL Makerspace, is the product of a large research study led by Toronto’s University Health Network that looked at the possibility of safely adapting one ventilator to be used on multiple patients at the same time — an unfortunate necessity during the time of Covid-19. The open-source design can be rapidly duplicated anywhere with help of 3D printing technology.

The device uses about $2 of plastic, a cheap and simple alternative to splitting a ventilator with expensive hospital-grade components.

The project involved a partnership with the with UHN research team led by Dr. Joe Fisher, Azad Mashari, Jay Han and Devin Singh. Alongside medical engineer Gad Acosta, we embarked on a journey of rapid design and prototyping for a research project centred around the development of an individualized automatic lung ventilation system for multiple patients using a single ventilator. The design took its inspiration from an original concept by Joe Fisher published in 1994.
