Development of an Electrically Powered Medical Suction Device for Clinical Applications in Developing Countries

Morufu Olusola Ibitoye

Abstract


In clinical settings, the process of suction is the removal of biological fluids using vacuum technology. This study sought to design and develop an inexpensive suction device for the facilitation of airway management in patients under emergency or critical care. The suction device was fabricated based on the design specifications. The device was designed to be able to aspirate biological samples at low (70 mmHg), medium (90 mmHg), and high (120 mmHg) pressures using catheters of 9.4 mm and 3.3 mm diameters. These pressures were selected to enable the device to be useful for infants and elderly patients. The developed device passed the required electrical safety tests using the standard electrical safety analyzer by Fluke. For example, the leakage AC and DC were 0.1 µA AC and 0.0 µA DC, respectively, suggesting that the device is safe for use on patients. We are confident that the introduction of this inexpensive device (<USD 65) to rural healthcare centers will be able to address the critical shortage of suction devices for trauma and critical care.
