IFSP researchers are participating in a multidisciplinary team articulated by professionals from the Polytechnic School (Poli) at USP, which developed the design of an emergency pulmonary ventilator to supply the possible demand for the hospital device due to the Covid-19 pandemic, the INSPIRED. The team involves researchers with extensive experience in the fields of biomedical, mechanical, mechatronic, energy, electronics and production engineering, as well as experience in prototyping and testing of devices used in medicine.

Among the members of the development team are Câmpus Sorocaba professors André Martins and Sérgio Shimura, the general director, Denilson Mirim, and the scientific initiation student, Anderson Blank. According to Denilson, the IFSP researchers worked mainly to establish the human-machine interface, in the C programming language, and its integration with the prototype's touch screen display.

The prototype INSPIRED It is a low-cost open lung ventilator, produced entirely with national technology, which uses components widely available in the Brazilian market. The prototype development is concluded, although it continues to be constantly improved.

According to Denilson, the Câmpus Sorocaba team delivered on Monday (27) two devices in its latest version. From now on, the prototype will only receive incremental changes. “IFSP is still participating in this stage, including new features that will compose the final version of Inspire. Later, we will participate in the monitoring of the manufacturing and testing phases ”, he said.

According to a statement released by the project team, on the 17th, 18th and 19th of April, studies were carried out with four patients, on the premises of the Heart Institute of the Hospital das Clínicas of FMUSP. According to the document, INSPIRE was considered approved in this study, including in the assisted mode controlled by pressure, without any complications. The respirator still needs to be approved by the health validation agencies, such as the National Health Surveillance Agency (Anvisa), in order to be manufactured. According to the development team, the respirator should cost 15 times less than the cheapest model on the market.

Professor Denilson stressed the importance of participating in the development of a much-needed solution at this time. According to him, society is going through an unprecedented situation, both from the point of view of the pandemic and from an attempt to deny science that has never been seen before. “We, teacher-researchers, see in this context the opportunity to contribute to society in a solution that can save lives and also reaffirm the value of science and public educational institutions, which have been the target of denying its importance for building a more just society and opportunities for our youth, which will be the future of our country ”, he said.
