110 emergency ventilators were created from CPAP machines, meeting the university’s initial goal of developing ventilators from readily available medical components.
Application: Valves to control oxygen flow in repurposed CPAP machines.
Customer: U.S. university.
Challenge: This project involved converting continuous positive airway pressure (CPAP) machines into ventilators. These repurposed machines required the addition of two valves to control the oxygen flow during inhalation and exhalation.
Solution
To drive the emergency ventilators, Emerson provided two ASCO Series 210 solenoid valves. The university, already an existing end-user of ASCO products, selected this valve
after having the models on-hand in its facility. The versatile Series 210 features precise instrumentation, that controls liquids, as well as corrosive, air and inert gases with
reliability in applications ranging from medical equipment to air compressors. These high-flow valves also come in a wide range of pressure ratings, sizes and resilient materials including brass and stainless steel— achieving long service life and low internal leakage in critical applications. An oxygen-cleaned version of the Series 210 valve was provided to withstand the high concentration of oxygen that would be administered to patients.
Results
Emerson helped the medical team quickly deliver 110 ventilators to hospitals responding to COVID-19. This innovation, coupled with Emerson’s quick response time, enabled the university to provide much needed medical equipment and care to local and developing areas.
