COMPLETE SPECIFICATION
The following specification particularly describes the invention and the manner in which it is to be performed:

Field of the Invention:
The present invention relates to develop Internet of Things (IoT) assisted Oxygen Concentrator for supplying pure quality of oxygen to patient that in need of external supply of oxygen during such situation arises.
Background of the Invention:
A rise in chronic illness cases and even environmental pollution contribute to increasing demand of supply for pure oxygen. During the previous two years when the number of health professionals was constrained, health staff found it impossible to provide individualized care to each and every patient. There has been an upsurge in the demand for oxygen.
There are oxygen concentrators available in India, but they must be handled by trained medical personnel, and they can only supply oxygen to a single patient at a time. Even though India is a developing nation with the highest population, they are only available in 3, 5, and 10 Litres per Minute (LPM), which can only accommodate up to 2 patients. The demand for oxygen concentrators is gradually rising as a result of an increase in illness cases as well as environmental pollution.
Therefore, an IoT-enabled oxygen concentrator is required. With the help of sensors, it can measure the SpO2 level accurately, gather even the smallest variations in the patient's condition, and adjust the oxygen flow accordingly. It even has a specialization in maintaining and tracking reports and previous medical conditions rather than manually maintaining the present and past conditions.
Object of the Invention:
The main objective of the present invention is to develop oxygen concentrator using fundamentals of Pressure Swing Adsorption (PSA).
Another objective of the present invention is to supply pure quality of oxygen for human beings when it is required to do so.
Yet another objective of the present invention is to provide real time monitoring over consumption, and flow of pure oxygen supplying to human beings on smart devices using internet.
Yet another objective of the present invention is to control overall flow of pure oxygen through internet.

Yet another objective of the present invention is to acquire information related to quantity of pure oxygen supplied over specific duration of time interval.

Yet another objective of the present invention is to provide pure quality of oxygen to multiple human beings using same device at a time.

Yet another objective of the present invention is to provide real time monitoring over supply of oxygen to their relatives in case of pure oxygen supply to patient facing issue related to breathing.

Yet another objective of the present invention is to develop user friendly pure oxygen supplying system meeting requirements of World Health Organization.

Summary of the Invention:

The primary aim of the present invention is to develop a device, an IoT-enabled oxygen concentrator, which uses zeolites to quickly adsorb ambient nitrogen onto zeolite minerals under high pressure using a molecular sieve to adsorb gases (PSA technique). By removing nitrogen from the air, oxygen concentrators produce an oxygen-enriched gas that can be used by people who require pure oxygen. As of now, this idea will eliminate difficulties like locating medical personnel who are properly educated to use oxygen concentrators.
With the aid of a smart device, it also be able to handle numerous patients at once, since it will be able to display their medical data and adjust the oxygen flow rate based on their individual medical needs. It would be able to improve patient’s quality of life and even provide them with a better life.

Detailed Description of the Invention:
The following description relates to a particular manifestation of the present invention. The present invention relates to Internet of Things Assisted Oxygen Concentrator for Supplying Pure Oxygen.
An oxygen concentrator is a device that produces medical grade pure oxygen that may be used by both healthy people and those with any illness, including people with COPD, asthma, patients recovering from surgery, and people who are severely ill and need oxygen as a life support system.

The oxygen concentrator has been designed on the principle of Pressure swing adsorption and as per the guidelines of WHO. The process commences with the compressing of the air. The compressor (2) takes input as normal air but it gets filtered through a dehumidifier (1) that removes moisture from incoming air. That air goes through a heat exchanger as the compressed air gets heated up and needs to be lowered. At the end of the heat exchanger, the air comes out at room temperature which will be stored at the air storage unit (7). The purpose of air storage unit (7) is to provide a steady supply of air to the zeolite column.

The air storage unit (7) will supply the air when the MOSFET (15) opens and MOSFET (15) closes, the air passes through the sodium-based zeolite column with Granule size of 0.4-0.8 mm at the pressure of 3 bar. At such pressure, zeolite adsorbs the nitrogen and the rest of the air passes through. Zeolite column will be at lower pressure thus zeolite loses its ability to hold the nitrogen and it releases the nitrogen. A small portion of the air from zeolite column will go to zeolite column to push the trapped nitrogen outside. This cycle will continue, when column generates the oxygen zeolite column will evacuate the nitrogen outside and when zeolite column generates oxygen zeolite column will push the nitrogen outside. The oxygen-rich air will be stored at the air storage unit (7). Also, the MOSFET (15) has been used instead of relays to control the solenoid valve to prevent fire.
Through the touch screen (16) display the flow of oxygen can be controlled. The flow controller (9) will allow the said amount of air to pass through. Furthermore, the flow sensor (9) and oxygen level sensor (8) will assess the quality of air. After that, the oxygen rich air will go to a humidifier (10) with an anti-bacterial capacity that will remove microbes and add the required moisture to oxygen. This oxygen will be supplied to the patient.

Alongside this, the room temperature and humidity will be monitored through a DHT11 sensor (digital temperature and humidity sensor). The patient can check their SpO2 and Beats-per-minute (BPM) by putting their finger on MAX 30102 sensor. The MAX30100 is an integrated pulse oximetry and heart- rate monitor sensor solution. Also, the sound level of the oxygen concentrator will be measured to keep it under the standard sound level. All of the captured data will be displayed on the touch screen display (16) through which we can visualize, control and optimize the performance of the device.

By using the principles of IoT (Internet of Things), a standard oxygen concentrator gadget monitors SpO2 and regulates oxygen flow rate in accordance with SpO2 measurements with the least amount of user intervention.

The experimental results were as per the expectation: At the 0-5 lpm the oxygen level was found to be in the range of 91-93%. At the 6-10 lpm the oxygen level was found to be in the range of 88-91%. At the 11-20 lpm the oxygen level was found to be in the range of 84-88%. Also, the SpO2 level in the patient and device flow rate was found to be inversely proportional.
