Stand Alone Patient Monitoring System

Project Title

Stand Alone Patient Monitoring System

Project Area of Specialization Biomedical EngineeringProject Summary

Everyday, many lives are affected because of patient’s ignorance. Real time physiological parameters are not efficiently measured in hospitals and clinics. But, now–a–days, healthcare is given extreme importance by each country with the advent of novel corona virus. Due to the internet of things (IoT), that allows the interconnecting of devices over internet network. It facilitates the digitalization and automation of manually operating devices. Among one of them is the patient monitoring system. The main purpose of our project is to improve the monitoring parameters of healthcare system. To make low–cost, low–power consuming and reliable wearable device that can be upto the need of the most of the patients. A stand alone patient monitoring system can work in real – time and is efficient to those that used earlier. Allow monitoring of the patient data having a proper authentication access in security and privacy to only the healthcare providers or doctors at remote places, can diagnose them at any place and at any time.

Project Objectives

To study the continuous monitoring of physiological parameters or vital signs including heart rate, Blood pressure, oxygen saturation in blood, temperature, breathing rate, humidity and ECG of the patients that are at far distance and require the regularly checkup from patient–centric location by the low–cost wearable (smart bands, smart shirts and smart watches) stand alone patient monitoring system and by which data can be shown on OLED screen and shared by low–power consumption wireless medium over the cloud and from there that strictly–access authorized data can be sent to the healthcare providers or doctor and at same time stored in the database server (Thing Speak) so, data from those servers can be retrieve for future diagnosis. It maintains a secure and privacy–based exchange of the monitored data between patient and doctor, provide an easy way to maintain proper a checkup of many patients at a time.

Project Implementation Method

Our proposed system in which physiological parameter sensors having heart rate sensor, oxygen saturation sensor, blood pressure sensor, temperature sensor, humidity sensor and ECG sensor are attached to the patient at home or any other location. The patient data from sensors are transmitted to a microcontroller (Arduino UNO). A Wi–Fi module (ESP8266) and a buzzer is connected to the microcontroller. If the data of patient is in range then it will pass through forward without buzzer alarm. A Wi–Fi module send that data to the cloud where it is stored in database server storage, to retrieve that data for diagnose in future and also delivered to the doctor by a smart phone or gadgets to give him/her proper diagnose at right time. If any of the patient vital signs got out of range then the buzzer starts alarm and that make a healthcare taker or a nurse near to the patient to look over the patient and take proper precautionary measure in form of medication for a patient. At the same time the emergency alert is also send to the doctor and stored in database server storage too through the cloud server. Due to this proposed system, a patient is connected with a doctor through monitoring system that works in real–time and consumes low–power at high transmission of data for proper treatment and diagnosis.

Benefits of the Project

• Real time support for improved health outcomes and quality of life.
• Provides extension of care at home after discharge helping to prevent emergencies.
• Ability to continue monitoring patient’s health, regardless of patient location, even when not at home.
• Online illustrations for selectable parameters and recording of all procedure parameters in the interim selectable by client, which is most helpful for future investigation and appointment location.
• All parameters can be seen on mobile telephones.
• It can be additionally utilized as a part of seniority home to screen the different parameters of the wiped out individual in maturity homes.
• State–of–the craftsmanship innovation framework.
• Supports countless sensors to the framework.
• 8 autonomous simple channels accessible, for future enhancement.
• More accountability from patients and care providers. 

Technical Details of Final Deliverable

The proposed outcome of this project is to give proper and efficient medical services to patient by connecting and collecting data information through health status monitors which would include patient heart rate, blood pressure, ECG, temperature, breathing rate, oxygen saturation, humidity and sends an emergency alert to patient’s caretaker outside the room or to the doctors at other location with his current status and full medical statement in real–time monitoring. The sensors used for the monitoring of physiological parameters should place properly by the tapes or Velcro straps. Also, use of the finest quality embroided textile–based electrodes for ECG that may not cause any inflammation or allergic reactions after using it for a long–time and can be used for so readings without placing it into waste after one reading just like the Ag/AgCl based wet–electrodes and even dry–metal electrodes. It involves nothing but require washing and it is noted by comparing the efficiency of the textile electrodes with Ag/AgCl and dry–metal electrodes that after 10 washing cycles of textiles electrodes the result of ECG were same as that of using Ag/AgCl electrode for only one time monitoring as, it would be helpful for using textile – based electrodes for many times make us able to reduce in the cost. Second, thing is to ensure the security and privacy of the patient data, authentication is key security mechanism for IoT architecture design, as the hackers need to have an access to the IoT system to start their attack. This technique secures the communication within the IoT network through approving the identities and their right for accessing to the authorized resources in the network. Therefore, to provide protection against those security challenges it involves the traditional authentication methodology involving physical layer key generation mechanism and cryptography mechanisms (elliptic curve cryptography), can suffer from both high latency and complexity in network and help in making a protection gradient against the different phishing, contaminants–virus and malwares (adware, spyware, ransomware and trojans).
