| DESIGN NAME: Vox PRIMARY FUNCTION: Pneumatically Driven Ventilator INSPIRATION: The CoVent-19 Challenge is an open innovation effort founded by Mass General Hospital residents and anesthesiologists to close the gap between available resources and ventilator shortages around the world. Out of more than 200 submissions, ours is one of two winning designs selected to continue efforts in manufacturing, and eventually, validation testing and FDA approval. UNIQUE PROPERTIES / PROJECT DESCRIPTION: VOX is a rapidly deployable, pneumatically-driven ventilator that prioritizes modularity, uses off-the-shelf solutions, and is optimized for a Covid-19 healthcare context. VOX costs less than $1,000 to produce and can be assembled in under 4 hours. VOX utilizes the ubiquitous IV pole to enable speedy and simple mounting, height adjustability for user comfort, easy transport, and efficient storage. Its built-in dashboard functionality allows for remote monitoring and operability. OPERATION / FLOW / INTERACTION: Our final design, VOX, is a rapidly deployable, pneumatically driven ventilator that prioritizes modularity, uses off-the-shelf solutions, and is optimized for a Covid-19 healthcare context. VOX costs less than $1,000 to produce and can be assembled in under 4 hours. VOX utilizes the ubiquitous IV pole to enable speedy and simple mounting, height adjustability for user comfort, easy transport, and efficient storage. Its built-in dashboard functionality allows for remote monitoring and operability from a single desktop computer or tablet for up to 4 ventilators, which drastically reduces personal exposure to disease and contamination. PROJECT DURATION AND LOCATION: San Francisco. Out of more than 200 submissions, ours is one of two winning designs selected to continue efforts in manufacturing, and eventually, validation testing and FDA approval. The two-round challenge aimed to present initial concepts and finalize CAD assemblies as part of the first phase, followed by a shortlist of finalist teams delivering functional prototypes in the final phase. The delivery of the final prototype is the result of continual collaboration and engagement with respiratory therapists (RTs), ICU nurses, and doctors who supported and informed the team’s goal of delivering a user-friendly, high-precision form factor that is easily assembled and adaptable to multiple healthcare settings.

PRODUCTION / REALIZATION TECHNOLOGY: VOX utilizes the ubiquitous IV pole to enable speedy and simple mounting, height adjustability for user comfort, easy transport, and efficient storage. Its built-in dashboard functionality allows for remote monitoring and operability from a single desktop computer or tablet for up to 4 ventilators, which drastically reduces personal exposure to disease and contamination. SPECIFICATIONS / TECHNICAL PROPERTIES: N/A TAGS: covid, ventilator, competition, social impact design, medical equipment, healthcare innovation RESEARCH ABSTRACT: In an effort to fully understand and prioritize the needs of various hospitals experiencing shortages, the team first looked closely at the context. Learnings from this presented clear opportunities to innovate for efficiency of storage, simplified manufacturing, and use of multifunctional equipment through design thinking and new technology. Our team convened with ICU nurses, respiratory therapists, and doctors throughout the process to gather information about the existing context and where users saw opportunities for improvement. We were able to partner closely with them to continue soliciting feedback as our design evolved, leaning on their real-life, in-the-field experience using and being around ventilators in the Covid-19 context. CHALLENGE: While ventilator care can be a life-supporting treatment, it can also cause fatal injuries from overstretching or force-inflation. This is a particular area of concern with the usage of plastic bag-valve resuscitators, also called Ambu bags, which have the potential to fluctuate in shape over time and develop variability in its delivery of ventilation. VOX’s pneumatic valve ventilation system offers the most reliable, consistent, and safe method of supplying oxygen and is designed around three key principles: Intuitive user experience. VOX utilizes the ubiquitous IV pole to enable speedy and simple mounting, height adjustability for user comfort, easy transport, and efficient storage. Its built-in dashboard functionality allows for remote monitoring and operability from a single desktop computer or tablet for up to 4 ventilators, which drastically reduces personal exposure to disease and contamination. Leveraging existing and familiar user behaviors, VOX is also fully functional from the device itself through a user-friendly touchscreen monitor, oxygen boost & alarm silencing buttons, and rotary dial for intuitive navigation, incremental adjustments, and legibility across generations of healthcare professionals. Simple alert statuses with streamlined management pairs banner messaging with highlighted alerts for quick scanning and comprehension. Volume control and sound signatures are also available by alarm type. Simplified architecture. Ventilators provide an incredible range of capabilities and features. VOX enables exploration of alternative technologies to tailor functionality based on individual setting needs. Its pneumatic system leverages existing pressurized air systems in place of mechanical actuation, offers a lighter and more manageable form factor, and has built-in overpressure relief. Intelligent manufacturing. The real opportunity behind VOX lies in delivering a product that can be made quickly, by implementing simple manufacturing processes and affordable off the shelf components. Production of its 3D printed elements utilizes advanced polyjet printing technologies for abridged assembly and reduced cost. Combining VOX’s outer shell and housing, the unit leverages multi-material and multi-color printing to produce the venting, fasteners for assembly, Venturi tubes, and UI details like buttons and icons. All components were specified for critical size and form. Aluminum was selected deliberately for the front and back plates (single bend for front plate) for durability and protection. The simple assembly of VOX is defined by its minimal use of fasteners, lack of adhesives, and modularization of its production workflow.
