Project Summary

The COVID-19 issue has trigger respiratory inadequacies that are intended to assist patients with extreme breathing symptoms. Intense respiratory disappointment might happen in patients with COVID-19. Acute respiratory distress syndrome (ARDS), which actuates serious challenges breathing because of spilled blood into the lungs. The ventilation framework can support these patients' consideration by providing when the hidden sickness goes through its course, oxygen. Satisfactory oxygen supply is a base for emergency care and COVID infection will decrease ARDS wounds and hypoxemia passing.

Since the expanding number of cases of COVID-19 can surpass the quantity of respirators available, many firms, Emergency ventilators have been created by academic testing groups and different associations under explicit administrative approvals.The need of the low cost ventilator configuration emerges in the year 2019. In 2019, we seen an extraordinary calamity that occurred in our reality around, which kills a considerable lot of the life and their fantasies. Furthermore; we call it as a name Covid-19 infection. Covid-19 is an intense respiratory condition which starts from a group of Covid-19 that reaches from the normal cold to the MERS. The serious issue that emerges from this is shortness of breath. At the point when it generally spread all in all worlds pushes to get more ventilators to get the Covid-19 patients.

The solution is to design a ventilator which can meet the symptoms and strains which COVID-19 can put on different people, would it be advisable for them they not approach a business ventilator as an economic requirement, or have confined admittance to a clinical facility credited to the influx of patients. This means that a compact ventilator focused on for lower hazards patients to be the ideal ventilator plan. This ventilator would allow for the short term out-patient care of low risk patients, thus allowing hospitals to focus on high risk patients. The lower hazard patients would then be permitted to be at home and away from emergency clinics where both the costs and dangers of coming down with sicknesses would be higher.The Ventilators are utilized in different circumstances that place different requirements on their design. Each application involves differences in the clinical condition of patients, operator experience, and demands of the environment. A single device is probably to be good for all circumstances and that is Emergency Ventilator.

Project Objectives

On the basis of our research work, it is observed that there is a need of reasonable Low expense ventilators in Pakistan to battle against COVID-19, likewise overseeing patients during this time challenging task. Our Aim is to design and provide an economical and user friendly emergency ventilator to overcome shortage of ventilators across the country.

Following are the objectives of the ventilator:

• To provide First Aid to those peoples who are suffering from breathing problems.
• To provide user-friendly device that can be operated easily by anyone and anywhere, regardless of any skilled person.
• To provide cost-effective substitute to ordinary ventilators.
• To provide emergency facility to remote areas.

Project Implementation Method

Ordinary ventilators used in intensive care units are refined devices. The guiding principle in their design is the provision of optimal lung ventilation. They incorporate precise but sizable pneumatic components intended to utilize piped gases and mains electricity. However, when transporting patients receiving ventilator support, these devices are rarely suitable because of their size, weight, requirement of external power, and rate of gas consumption.

Ventilators are compact devices designed to provide mechanical ventilation in settings where piped gases and mains electricity are unavailable. Modern engineering has afforded these devices a level of sophistication approaching that of a conventional intensive care ventilator.

Ideally, a portable ventilator, including oxygen and battery supplies, should be lightweight, robust, and able to function in demanding environments with little maintenance. It must use available gas or electrical supplies sparingly. It should be inexpensive, simple to operate, and provide a range of effective ventilator modes.

Ventilators are either controlled electrically or pneumatically. Ventilator grouping plans clarify the instrument by which a ventilator works. Innovative progressions with complex (chip controlled), double modes with worked in intra-or entomb breath input systems have made the arrangement patterns more troublesome. This is additionally compounded by the shortfall of a generally settled order framework for ventilators. To add to the rising intricacy, different ventilator makers have given different exclusive names for a similar method of ventilation. An illustration of this is versatile strain control (PC), which relying upon the ventilator brand, is likewise called pressure-directed volume control, versatile tension ventilation, auto stream, volume control additionally, volume-designated PC, and tension controlled volume ensured. traces the fundamental parts of a ventilator conveyed breath, which gives a superior comprehension of how these modes work.

We propose to implement the Low-Cost Ventillator using an AMBU bag being compressed and decompressed by a mechanism controlled with stepper motors. The compression and decompression would be governed by the Pulse Oximeter and a pressure sensor. We will record heart beat per minute too which would be provided by an embedded sensor which combined oximeter and pulse monitor in a single package.

Benefits of the Project

The overall medical community currently faces a critical deficiency of medical equipment to address the COVID-19 pandemic. Specifically, this is the situation for ventilators, which are required during COVID-19 related therapy at beginning, during the serious consideration stage and during the exceptionally expanded recuperation times. Companies are increasing creation, yet this won't be adequate to satisfy the need as per the current forecasts. There is a wide spectrum of devices, ranging from highly sophisticated through to less complex units helpful in the milder periods of illness. From pandemic emergency in Pakistan we have been inspired to cater the local shortage of this clinical equipment like Ventilators and develop a fairly automatic mechanical ventilator that could be used in emergency medical units in hospital just as portable clinical units, for example, ambulances to give emergency ventilation utilizing an Ambo pack based arrangement to patients affected with COVID-19.

Ordinary Ventilators do not have 100% Efficiency (Their Efficiency is about 90-95%). The Cost of these Ordinary Ventilators is so high. According the performance of a Portable ventilator, it is 70% efficient as compared to ordinary ventilators of high cost. This portable ventilator has quite effective performance with Low Cost.).

Technical Details of Final Deliverable

The planned framework comprises of a microcontroller (Arduino); it will play a fundamental part in this framework. It will control every part like motor, gear mechanism, sensors, LCD screen etc. The activity of the Ambu bag will be done using the stepper motor attached with a gear mechanism. 

The pressure, volume and breath rate will be controlled through the input by a sensor which would record the patient's Oxygen levels and Heart Rate. LEDs will be used which to indicate the status of operation. The gear mechanism will permit the ambu bag to flow the air into the lungs by squeezing the ambu bag through air conveying tubes. These tubes will be attached to the patient's respiratory system. After the compression, the gear mechanism will go in reverse, and this will permit the Ambu bag to fill the air once more. Consequently, whenever the motor would turn, the Ambu pack would get squeezed and in turn it will emulate the process of breathing for the patient by filling and unfilling their lungs periodically. Hence, this framework will help the patient for the artificial respiration.

The final deliverable will be a portable, low-cost ventillator which will be housed in a metallic or acrylic assembly. It will be controlled using an Arduino, with the paramters being displayed on an LCD. The Ambu bag would provide the artificial breathing using the patient's parameters from Pulse Oximeter and another Pressure Sensor would help control how much pressure the patient would require from the Ambu bag.
