Insights
A low-cost mechanical ventilator, "NISHASH," was developed to address the critical shortage of ventilators during the COVID-19 pandemic. This accessible medical device provides automated oxygen delivery for respiratory support, particularly in resource-limited settings.
Area of Science:
- Biomedical Engineering
- Medical Device Design
- Public Health
Background:
- The COVID-19 pandemic highlighted a global shortage of medical equipment, particularly ventilators.
- Developing countries like Bangladesh faced severe challenges in providing adequate ventilator support due to high costs and limited availability.
- Respiratory complications from COVID-19 necessitated urgent solutions for mechanical ventilation.
Purpose of the Study:
- To design and develop an affordable, automated mechanical ventilator named "NISHASH."
- To address the critical shortage of ventilators in Bangladesh and similar resource-limited regions.
- To create an easily buildable and portable ventilator system.
Main Methods:
- Development of a prototype mechanical ventilator using electromechanical instruments.
- Implementation of an automated digital feedback system for precise oxygen flow control.
- Design focused on lightweight, portable, and user-friendly operation with multiple selection modes.
Main Results:
- A functional prototype of the "NISHASH" mechanical ventilator was successfully developed.
- The ventilator system offers automated oxygen delivery tailored to patient requirements.
- The estimated cost of the ventilator is under $90, utilizing globally available components.
Conclusions:
- The "NISHASH" mechanical ventilator presents a viable, low-cost solution to address ventilator scarcity during pandemics.
- This innovation can significantly improve respiratory care accessibility in resource-constrained healthcare settings.
- The project demonstrates the feasibility of developing essential medical equipment affordably and efficiently.
Abstract:
COVID-19 has elapsed all over the world with massive losses which indicate the lack of availability of medical equipment during the pandemic such as a ventilator. This is exemplified by the densely populated country Bangladesh who unable to maintain COVID-affected people because of the ventilator. Due to the higher price, unavailability, and manufacturing defection, most medical are unable to purchase this ventilator which causes terrible death for a respiratory problem. Of these cases, this paper represents a way to escape this problem and proposed a mechanical ventilator named "NISHASH" which will help to anticipate COVID affected people and higher price of the ventilator. Through the electromechanical instruments, a prototype lightweight easily moveable where preciously it automatically controls with digital feedback system ventilator which fulfills oxygen flow based on patient requirement are developed with different selection mode. The aim was to design and develop inexpensively automated easy to build to minimize the extreme shortage of the ventilator in Bangladesh. In this model of a mechanical ventilator, the cost is less than $90 where components are available all over the world.
