Design And Fabrication Of Automatic Medical Ventilation System

Abstract

Ventilator device are external devices that are designed to assist a patient to perform a particular task. It is to keep up or improve a breathing ability of a person if he encounters problem in his own breathing. Ventilators play a vital role in human’s life. It is a piece of equipment, software program or product system that is used to increase, maintain, or improve the functional capabilities of persons with disabilities in breathing period. This paper deals with the hardware design of a lab model ventilator. A prototype model of the ventilator has been designed and tested. Scripture under sight is defining the robustness and functionalities of ventilator which is not only easily transferable as well as it is very low cost and economics friendly. It is designed under the basic idea of being incorporated in huge human catastrophes in poorly resources enriched environments. It functions without human operator as it delivers breaths through the compression of an orthodox bag-valve mask. Different functions need to be performed for the purpose of ventilation i.e. pressure and required number of breathes per minute is managed by an easy to use input board comprising of buttons. In addition to that it also contains an alarm of high temperature for patient system as well as an assist control. This piece of prototype is cost effective as well as energy efficient as far as the present technology in ventilators is concerned.
