The MEDUMAT Transport ventilator moves a mixture of oxygen and air into and out of the lungs of patients who require breathing support. Developed by Weinmann Medical Technology, MEDUMAT Transport is designed for use in emergency care and during transport for intrahospital or interhospital transfers. As an emergency medical device deployed in a wide range of operating conditions, the MEDUMAT Transport must be portable, versatile, and exceptionally reliable.
Weinmann engineers used Model-Based Design with MATLAB® and Simulink® to develop the embedded software for MEDUMAT Transport. This approach not only streamlined production; it also helped Weinmann work with TÜV SÜD to certify MEDUMAT Transport to ISO/IEC 62304, ISO 10651-3, DIN EN ISO 13485, and DIN EN ISO 14971 standards.
“MEDUMAT is orders of magnitude more complex than earlier ventilators that we have developed,” says Dr. Florian Dietz, head of predevelopment emergency medicine at Weinmann. “Model-Based Design with MATLAB and Simulink enabled us to handle the increased complexity, and it was instrumental in our achieving compliance certification. Working with models instead of handwritten code makes the embedded software easier to maintain and reuse, and helps us explain the technology to a certification authority.”
