3D Printers Facilitate Custom Valve Production for Respiratory Support in Brussels

In Brussels, 3D printing technology is actively supporting medical professionals by enabling the creation of custom-made valves for respiratory support. This innovation is a direct response to the strain on medical resources, particularly the shortage of ventilators, by adapting readily available full-face snorkelling masks for use with BiPAP machines. The process leverages the expertise of a university spin-off company to produce essential components that can help patients with severe respiratory issues.
Custom Valve Design for Snorkelling Masks

Frederic Bonnier, a respiratory physiotherapist at Erasme Hospital and a university teacher, led the design of a specific valve. This valve is engineered to attach to the top of full-face snorkelling masks, the area where the snorkel would normally be placed. Its purpose is to create a secure connection point to standard BiPAP (bilevel positive airway pressure) machines, which deliver pressurised air to patients. This adaptation aims to provide an alternative for patients experiencing severe respiratory distress, potentially avoiding the need for tracheal intubation and mechanical ventilation.
Collaboration with Endo Tools Therapeutics

The development of these custom valves has been facilitated by Endo Tools Therapeutics, a private spin-off company associated with Brussels' ULB university. This entity possesses specialised knowledge in the application of 3D printing for medical purposes, making it instrumental in the production of the necessary components. The know-how of Endo Tools Therapeutics has been crucial in translating the design concept into functional plastic valve connectors that are now ready for testing.
Addressing Shortages and Improving Patient Comfort

The initiative to adapt snorkelling masks stems from the global scarcity of respirators and hospital-grade BiPAP machines, exacerbated by the high number of Covid-19 patients requiring breathing assistance. The snorkelling masks, donated by sports retailer Decathlon and originally made in Italy, offer a potential stop-gap solution for patients who are not yet in critical need of intensive care but still require respiratory support. Furthermore, Bonnier noted that these masks are perceived as more comfortable for patients than traditional hospital masks, which can cause skin irritation. However, he cautioned that these adapted masks are intended for single use due to a lack of medical-grade sterilisation capabilities.
