MAR artificial respirator for IMV

grabcad

Due to the crisis caused by the pandemic of Covid19, an artificial respirator has been developed in MOSE Serveis d'Enginyeria SLPU, in little more than a month.MAR is an artificial respirator for invasive mechanical ventilation that has been tested and approved by Hospital del Mar in Barcelona. It's a "war" machine created with industrial elements easy to supply and fabricate.There were many versions of this project, some of them including a vacumm pump to supply air. The last version uses the hospital medical facilities for the air supply. MAR uses solenoid valves, pressure probe, overpressure valves...all the mechanic equipment is controlled with a PLC. This machine allows the control and monitor of all the parametres required with a HMI screen: breaths per minute, inspiration / expiration ratio, PEEP valve, oxygen level... It's a safety machine: it has an emergency stop and an acosutic alarm, also an external power supply with 10 minutes of autonomy.The purpose of this project was to help people in the chaotic situation we had to live. Maybe now it's too late but it can be an inspiration for future projects. Appreciate your attention.
