Thanks to a plastic part, the engineering team transformed sports equipment into an effective protective mask against the Covid-19.
AT From the diving mask marketed by Decathlon, engineers from the Belfort-Montbeliard University of Technology (UTBM), in Sevenans (Territoire de Belfort), have developed Protective mask prototype against the Covid-19, reports France Bleu Belfort-Montbeliard. The model, intended for health personnel, was imagined with the Trevenans hospital.
A 3D printed plastic part has been added, allowing, “by a connection mechanism, to accommodate specific respiratory filters”, explains the Trevenans hospital in a press release. The modification made on the masks guarantees “optimal protection of personnel against inhalation of the virus, in addition to protection against splashes on the face provided by wearing a mask”says the hospital.
Unlike surgical masks, the university model is reusable: “It is enough to disinfect them by soaking, to change the connecting piece provided by the UTBM and the filter between each use”. Decathlon donated 65 masks to the hospital. The UTBM then used its entire fleet of 3D printers to be able to produce around sixty masks per day, and meet the needs expressed by the resuscitation service.
A second prototype has also been developed by UTBM engineers: a visor offering suitable protection for carrying out certain treatments. It will be used in all hospital departments, in addition to wearing the FFP2 mask.
These two prototypes were validated on Monday March 30 by the resuscitators, the hygiene service and the pharmacists of the hospital. Their production was launched at the same time.
