SMART REMOTE SENSING DEVICE FOR MANAGEMENT OF COVID PATIENTS FIELD OF THE INVENTION

The current disclosure is mainly linked to the real time remote sensing of various parameters like (patient's oxygen level, body temperature, pulse rate and humidity level) related to the monitoring of covid 19 patients either at hospital or in home isolation. The system is also equipped with Ambu bag which operates automatically that can be used to save the life during the patient is rushed to the hospital.

BACKGROUND OF THE INVENTION Like the 1918-20 Spanish flu, the second all-India surge of the Covid-19 pandemic has been more devastating than the first. It has also appeared to be different from last year's surge in several ways, increasing worries and anxiety. In second wave the main symptom observed, is the sudden drop of oxygen level in patient and India faced the crisis of shortage of oxygen that caused the loss of lives.

In the second wave, shortness of breath is the most common clinical feature among symptomatic patients in the second wave. According to government statistics 54.5% of admissions in hospital were on the requirement supplemental oxygen during treatment.

For moderate cases, India's clinical management protocol recommends oxygen therapy as the primary form of treatment. The patient in this category requires oxygen beds.

During second wave of covid-19 in India, the scarcity of Oximeter and oxygen cylinders were the major cause for high death toll. As the third wave is expected shortly in India, the preparation to meet out the same must be our priority. The proposed system is really helpful for the patients who are not critical and in home isolation but suddenly their oxygen level drops and they urgently require medical help in order to save their lives. A number of patients have died on the way to hospital as their emergency was not met out in lack of oxygen cylinders. The proposed system is equipped with Ambu bag and helps to patient's survival while rushed to the hospital. As, the disease is highly infectious, utmost care is needed in patient's handing. This device also prevents spreading of disease as monitoring and management both can be done remotely.

SUMMARY OF THE INVENTION

The new strain of the virus in second wave is found to be more powerful and infectious, which leaves younger and healthy people in critical conditions as compared to first wave of covid 19, people are gasping for breath. There was shortage of enough doctors or healthcare workers that gave rise to surge of corona virus cases, this is also having repercussion on the patients who were suffering with other critical illnesses as they face undue delays in getting treated. The shortage of oxygen supplies is also definitely a drawback. During first wave last year, there was shortage of PPE kits and in the second wave working more deaths were recorded due to the shortage of oxygen supplies and the hunt for medications by hospital and patient relatives. Cases were recorded in masses every day, in search of oxygen people rushed to the hospitals and they faced the problem of unavailability of ICU beds.

In present work, we have developed an IOT based wireless healthcare remote sensing device/system which could provide real time online information of the patients under observation either in home isolation or in hospital. Doctors at hospital and attendants at home can monitor their COVID-19 patients remotely. The system is smart enough to sense continuously patient's oxygen level, body temperature, pulse rate and humidity level. System is equipped with additional feature by which one can also sense the room temperature and humidity as well. All the readings taken can be displayed on LCD and can be monitored remotely using IoT. The major advantage of the system is that the monitoring of all parameters can be done from anywhere in the world because of IoT technology. The system not only measures the oxygen level of the patient but also provides the support to the patients in home isolation. The system is equipped with Ambu bag, so that the patient struggling with lower oxygen level can buy time to reach hospital safely. This Ambu bag is operated automatically by using servo motor. The frequency of inhalation can also be adjusted in system.

The system is incorporated with many features that enhance its utility. The patient monitoring is done remotely so that doctors at hospital and attendants at home are at least contact with patient and their chances of getting infected are less as covid-19 is highly infectious disease. This system is connected with internet using node MCU Wi-Fi module which can display real time data that could be seen and accessed over internet using IOT technology from anywhere in the world. The features of the system are enlisted as below:

>As the disease is highly infectious, the remote monitoring and management becomes necessity. The patient, if he/she is not critical, can also monitor the parameters like oxygen level, pulse value, body temperature and humidity level at his/her own.

>With the help of IoT technology, the doctors/ward boy at hospital and attendants at home can also monitor the above mentioned parameters remotely as in covid-19 patients frequent monitoring of oxygen level and body temperature is required.

>If the patient is in home isolation and suffocates suddenly due to drop of oxygen level then there is provision of Ambu bag that can be used to save the life during the patient is rushed to the hospital. The Ambu bag is operated automatically not manually, hence it is user friendly.

>The frequency of inhalation in Ambu bag is also adjustable according to the requirement of patient's age group.

DETAILED DESCRIPTION OF THE INVENTION The new strain of the virus in second wave is found to be more powerful and infectious, which leaves younger and healthy people in critical conditions as compared to first wave of covid 19, people are gasping for breath. There was shortage of enough doctors or healthcare workers that gave rise to surge of corona virus cases, this is also having repercussion on the patients who were suffering with other critical illnesses as they face undue delays in getting treated. The shortage of oxygen supplies is also definitely a drawback. During first wave last year, there was shortage of PPE kits and in the second wave working more deaths were recorded due to the shortage of oxygen supplies and the hunt for medications by hospital and patient relatives. Cases were recorded in masses every day, in search of oxygen people rushed to the hospitals and they faced the problem of unavailability of ICU beds.

Remote sensing device/system is useful for monitoring the patients suffering from higly

infectious disease lie corona virus. The virus spreads mainly between people who are in close contact with each other, typically within 1 metre (short-range). A person can be infected when aerosols or droplets containing the virus are inhaled or come directly into contact with the eyes, nose, or mouth. The virus can also spread in poorly ventilated and/or crowded indoor settings, where people tend to spend longer periods of time. This is because aerosols remain suspended in the air or travel farther than 1 metre (long-range).People may also become infected by touching surfaces that have been contaminated by the virus when touching their eyes, nose or mouth without cleaning their hands.

If we look upon the challenges of second wave specially in India, we find that the second wave of the Covid-19 has left infected patients gasping for breath as hospitals in some states continue to face an acute shortage of medical oxygen and beds. The second wave of the Covid-19 pandemic revealed that how grossly unequipped India's healthcare systems were to handle the spike in the number of daily positive cases.

In present work, we have developed an IOT based wireless healthcare remote sensing device/system which could provide real time online information of the patients under observation either in home isolation or in hospital. This system is helpful in monitoring

patients either at home or at hospital remotely. As, covid patients need to be monitored continuously.The system is smart enough to sense continuously patient's oxygen level, body temperature, pulse rate and humidity level. System is equipped with additional feature by which one can also sense the room temperature and humidity as well.

During second wave, it was seen that the oxygen level of the patients drop suddenly and they pant for breath. Patients have no time to reach hospital and hey collapse either at home or on the way to hospital in lack of oxygen. In proposed system there is provision of Ambu bag that can be used to save the life during the patient is rushed to the hospital. The Ambu bag is operated automatically not manually, hence it is user friendly.

The block diagram of proposed system is shown in Fig. 1. The main components which are used in this system are listed below;

1. Node MCU 2. Oximeter Sensor MAX30100 3. Temperature sensor DS18B20 4. Temperature and humidity sensor (DHT11) 5. LCD 16x2 6. Servo motor 5V 7. Buzzer

Claims

CLAIMS In order to meet out the problem addressed, conventional Oximeter is available in the market. The use of conventional Oximeter is limited as it senses pulse and oxygen level only. We claim >The conventional pulse Oximeter only senses oxygen level and pulse value while the proposed system not only measures oxygen level and pulse value but also measures body temperature and humidity level along with room temperature and humidity level. >With the Conventional Oximeter remote measurements/monitoring is not at all possible while proposed system provides remote monitoring of required parameters of covid patient using IoT technology. >The proposed system works like a life saving devise to some extent as it is equipped with Ambu bag which operates automatically and adjustable inhalation frequency is added feature. The proposed system has following benefits. >User friendly >Cost effective >Equipped with Ambu bag to maintain the sustainability of the patient >Can sense and provides display on LCD of pulse, oxygen level, body temperature and humidity, room temperature and humidity >Remote sensing using IoT technology
