Health Care Monitoring System

Abstract

The new outbreak of Coronavirus poses a major threat and has been declared a global public health emergency. Whole World is trying to stop the virus but no efficient tool and strategy is there to control it. Monitoring of Patient’s health remotely is really important, especially for patients suffering from a long-term disease. Health care monitoring system nowadays require instant sensing, precision predictions and immediate response with medication which contains sensing modules to measure parameters like temperature of the body, beat rate of heart, sweat rate and transfer it to the computer so that the health condition of a patient can be analysed remotely. Thus, it reduces the doctor’s workload and also gives accurate results. Further this system uses GSM technology which enables the monitoring of all parameters on the mobile phone. The inputs are analysed through a micro controller platform from the patient and any abnormality felt by the patient causes the monitoring system to send a message to the respected caretaker. These are the essential data for the future analysis and review of a patient’s health condition.

The main purpose of this health care monitoring system  project is to make a health monitoring system where one can check pulse rate, and body temperature, and even monitor their health condition. This system also provides a fall alert. Body pulse can be checked with the help of a pulse sensor. Body temperature can be checked with the temperature sensor. If there is any fall detected, the buzzer will be activated, and a message will be sent to the caretaker.

Introduction

“Health” is the state of physical, mental, and social well-being. By taking good care of the body, one can be fit and healthy, as there is a saying that a healthy mind resides only in a healthy body. As we grow, we become older, and as we grow older, we are more prone to chronic diseases. Health care monitoring system have rapidly evolved recently, and smart systems have been proposed to monitor patient current health conditions, in our proposed and implemented system, we focus on monitoring the patient’s blood pressure, and his body temperature. Based on last decade statistics of medical records, death rates due to hypertensive heart disease, shows that the blood pressure is a crucial risk factor for atherosclerosis and ischemic heart diseases; thus, preventive measures should be taken against high blood pressure which provide the ability to track, trace and save patient’s life at appropriate time is an essential need for mankind. In the existing system, one had to consult the doctor for a periodic health checkup. As this is a time consuming and very tiring process  one would neglect the periodic health checkup, but in the proposed system, there is no need to consult the doctor. One can check and monitor his/her basic parameters with this system. This system can be made more efficient with the technology arising. As it is said that prevention is better than cure, one can monitor his/her health. This system is more efficient, cost-effective, and economical compared with the existing system.

Components Required

Hardware Requirements

Flow Chart

First temperature and pulse values are measured. If the temperature is more than the required temperature, if the pulse rate is less than the required pulse rate then a buzzer will be activated and a message will be sent to the user through the GSM module.

Working

The data taken by the temperature sensor and pulse sensor are first converted to electrical signals and sent analog data to the controller. Output devices like the GSM module and buzzer act upon the data given by the output devices and give an alert to the guardian or consultant doctor if any abnormal signals are detected by the sensors.

Conclusion

Hence, the health care monitoring system is successfully built using the GSM module. It allows patient health analysis quickly. In the future, we can replace the Arduino with raspberry pie which increases the health monitoring parameters in detail.
