Design of a Multi-Control Objective Rescue Mechanical Ventilation System (Linshomator)

In the recent years, the need for low-cost emergency ventilation system has increased unprecedentedly. Mechanical ventilation systems are widely used to cater to sudden oxygen demands, low breathing rates and critical conditions during Bradycardia and Tachycardia. In this research, a new design of mechanical ventilation system synced with the tidal volume requirements of the patient using a piezoelectric belt has been proposed. The device proposed, has various modes of ventilation – ACV (Assisted Controlled Ventilation), SIMV (Synchronized intermittent mandatory ventilation) and NIV (Non-invasive Ventilation), depending on the patient’s requirements. A digital interface or user-friendly software has also been developed to help the medical professionals easily monitor a patient’s medical conditions. Finally, the automation which controls the ventilation mechanism of the device has been tested and validated with a conventional ventilator and it has been found that the accuracy of the device in terms of delivering the exact quantity of air into the patient according to his requirements has been improved significantly. Further, the comparative study of the experimental data indicated that 5-10 % error in detecting inhale and exhale attempt of a patient was detected with the conventional ventilator.
