This paper describes the design and prototyping of a low-cost portable mechanical ventilator for use in mass casualty cases and resource-poor environments. The ventilator delivers breaths by compressing a conventional bag-valve mask (BVM) with a pivoting cam arm, eliminating the need for a human operator for the BVM. An initial prototype was built out of acrylic, measuring 11.25×6.7×8 in.3 and weighing 9 lbs. It is driven by an electric motor powered by a 14.8 VDC battery and features an adjustable tidal volume up to a maximum of 750 ml. Tidal volume and number of breaths per minute are set via user-friendly input knobs. The prototype also features an assist-control mode and an alarm to indicate overpressurization of the system. Future iterations of the device will include a controllable inspiration to expiration time ratio, a pressure relief valve, PEEP capabilities, and an LCD screen. With a prototyping cost of only $420, the bulk-manufacturing price for the ventilator is estimated to be less than $200. Through this prototype, the strategy of cam-actuated BVM compression is proven to be a viable option to achieve low-cost, low-power portable ventilator technology that provides essential ventilator features at a fraction of the cost of existing technology.

Abstract Background: The current need for pulmonary mechanical ventilation related to COVID-19 exceeds the ability of health systems worldwide to acquire and produce mechanical ventilators. The major cause of mortality in patients with this disease is hypoxemia secondary to an inflammatory storm in the lungs associated with thrombotic events. A partnership was established between the university and the private engineering and industrial automation sector to concept and design novel a low-cost emergency mechanical ventilator that could be rapidly available for use in emergency, transport or low-resource health care system, and attend the urgent demand of artificial respiratory system that is need worldwide. It was evaluated the viability of oxygenation and pulmonary ventilation with an emergency mechanical ventilation device called 10D-EMV in animal experiments. A two-stage sequential adaptive study was conducted in 10 sheep, divided into group I (PEEP valve close to the device) and group II (PEEP valve distal to the device). Each animal underwent mechanical ventilation for a total of 120 minutes. Results: The mean oxygenation in group I and group II were 368 mmHg and 366 mmHg, respectively, while the mean partial pressure of carbon dioxide was 58 mmHg and 48 mmHg. Conclusion: This study demonstrates the viability of the 10D device as a novel proposed emergency mechanical ventilator, in order to attend the pandemics demand. Further clinical studies in humans are needed to assess its safety and efficacy.

Abstract: Mass casualty incidents such as those that are being experienced during the novel coronavirus disease (COVID-19) pandemic can overwhelm local healthcare systems, where the number of casualties exceeds local resources and capabilities in a short period of time. The introduction of patients with worsening lung function as a result of COVID-19 has strained traditional ventilator supplies. Mechanical ventilator is a medical device which is usually utilized to ventilate patients who cannot breathe adequately on their own. Among many types of ventilators Bag Valve Mask (BVM) is a manual ventilator in which a bag is pressed to deliver air into the lungs of the patient. In present work, a mechanical system along with speed controller has been developed to automate the operation of BVM. The constructed prototype contains crank, powered by servo motor, supported by wooden frame. To bridge the gap during ventilator shortages and to help clinicians triage patients, manual resuscitator devices can be used to deliver respirations to a patient requiring breathing support. With principal dimensions of 0.54*0.64 m2 , bvm weighs 0.9 kg and DC power convertor for supplying power for a continuous operation, the prototype can be moved easily. The dimensions of the frame are selected as such to be compatible with the physical dimension of Ambu bag. The performance of the device was tested using Airflow meter which illustrates that the Tidal Volume vs. Time graph of the automated system is similar to the graph produced by manual operation of the BVM, but with a mean deviation of 0.182 Litres with manual operation and 0.1 Litres with prototype. For patients who require ventilatory support, manual ventilation is a vital procedure. It has to be performed by experienced healthcare providers that are regularly trained for the use of bag-valve-mask (BVM) in emergency situations.

AbstractIn order to test medical devices, industry increasingly uses simulators closely reassembling the behaviour of physiological systems. In the context of respiratory therapy, most available simulators are designed based on a ventilated volume. This highly adjustable volume allowing for fast dynamical changes often leads to very costintensive test devices, particularly when incorporating realistic spontaneous breathing. Therefore, in this article we introduce a novel concept for a low-cost lung simulator, capable of mimicking the ventilation behaviour of the human lung at the Y-piece of a mechanical ventilator. The proposed design does not require any enclosed spaces to hold inhaled air nor expensive precise linear actuators adjusting its volume. Instead, the setup is designed based on the design of a mechanical ventilator, connecting the system with one port to the ventilator and then dividing the hose into two independent branches. Each branch has an integrated radial fan and a proportional valve, controlling the inspiratory and expiratory flow, individually. The mass flow and pressure are measured at the systems inlet port, representing the condition at patient airway. In contrast to existing setups, the proposed design is not limited by the physical properties of a volume such as fixed maximum size, allowing the simulation of various types of patients and conditions. Numerical simulations to evaluate this system design showed the ability to generate a realistic spontaneous breathing pattern. With a first experimental setup it was possible to prove the feasibility of this approach, by generating common flow curves during spontaneous breathing. Building on this design, the approach could eventually lead to a more accessible method for testing.

This paper mainly focuses on the development of an efficient and adaptable breathing cycle for the patients who are suffering from respiratory problems. A precise and efficient lung circuit is designed by using MATLAB software. By considering the present circumstances caused by the COVID-19 pandemic, led to shortage of ventilators, numerous prototypes of low-cost ventilators are designed across the world [9]. The prime drawback with the low cost ventilators is that there is no peep control causes lung damage and has higher probability of causing Barro trauma this results high sedation to the patient, present model designed by producing a controlled peep that could provide better help to affected lungs.
