The University of Baghdad has registered a new patent in the field of designing and constructing a flat flow meter for mechanical ventilation systems. This patent belongs to Lecturer. Hassan Ali Hassan, the Director of the Department of Diwan Affairs and a lecturer at the Ibn Sina Center for E-Learning.
The discovery aims to manufacture five flat flow sensors using basic and three-dimensional printing techniques, which help address the critical need for pulmonary resuscitation devices, as evident in health crises such as the COVID-19 pandemic. The operation principle of these sensors relies on the five-flow technique (Fleisch pneumotachograph), which creates laminar flow within a bundle of capillary tubes. The airflow sensor is considered a crucial element in the artificial respirator.
The researcher has reached significant results indicating that the three-dimensional printed sensor with 33 semi-diverted capillary tubes and variable pressure taps meets the flow sensing requirements with less patient resistance during exhalation and a more linear response. Experimental data was correlated using an advanced MMF correlation with a square factor of 0.9999 and an error ratio of 1.68.
