A Tele-medicine System for Measuring Heart Rate, Blood pressure, And Drug Level Detection
Abstract:
This paper presents a current invention for monitoring the patient health by continuous observation.From today’s world of automation, the field of biomedical is no longer aloof. Application of engineering and technology has proved its significance in the field of biomedical. It not only made doctors more efficient but also helped them in improving total process of medication. The Patient monitoring system is also a new step in the automation of supervision for doctors. The basic idea behind this project is, it implies that weather a person is at home, on a trip, or at his work place, he/she can stay connected with the doctor and he can take immediate action if necessary. The Telemedicine system for doctors provides solution for this. It continuously provides following information to doctors. Heart pulse rate,Blood Pressure,andDrug Level detection.As used in hospital the same system can be used for a person who is not under the continuous observation of doctor, can check his/her vital signs using the sensors in this project if sensors output starts fluctuating above normal rate hence through GSM network sends an indication to doctor’s mobile immediately.
Existing System:
Nowadays, the use of a vital sign’s monitor is very common and not merely used at the hospitals as a monitoring system for patients. Generally, heart rate monitor was used by a person who cares about their heart to ensure that they have a normal heart rate. The early detection of the abnormal heart rate can help to prevent from the serious disease.the heart rate monitor is needed to determine the range of heart rate. This range of heart rate should be compatible with the normal rate to prevent from serious injury. Such digital display of target heart rate did not provide for ease of reading the display under the most conditions. This paper proposed an innovation to respond to this problems by providing a novelwearable bio med ical signal sensor devices for monitoring heartbeat,blood pressure. And drug level conditions at home easily, which displays the heart rate by LED-LDR Sensor and enabling a user an indication if any abnormality through GSM,and also blood pressure & drug or alcohol also monitored. The proposed innovation will be programmed to automatically suggest the user about their health conditions.
Proposed system:
There are three sensors used in the transmitter module. They are the, Heartbeat Sensor, Pressure Sensor and Drug detection Sensor. The heart beat sensor used here is 1157 Heart beat sensor. This sensor is designed to give digital output of heart beat when a finger is placed on it. When the heart beat detector is working, the beat LED flashes in unison with each heartbeat. This digital output can be connected to microcontroller directly to measure the Beats per Minute (BPM) rate. It works on the principle of Light modulation by blood flow through finger at each pulse. The software can be separated into two parts: the firmware running in the micro-controller on the front end analogue circuit board, the application program written using kiel software & dumped into the controller using flash magic. The program embedded on the microcontroller is written in Embedded C. The program contains the following: Conversion of analogue signals (heartbeat, blood pressure, drug level) to digital values and Indication of abnormal rate. Packetization of the collected data and the transmission of them through the serial communicat ion interface.
Conclusion:
Telemedicine system is very useful for senior citizens and physically challenged people who are suffering from variation of blood pressure level, and they can be rescued from sudden heart attacks. Using this system we can adjust the minimum and maximum levels of blood Pressure and heart beat level, if the persons BP and heart beat exceeds the levels then immediately the information will be passed through GSM to the concerned doctor so that we can save the life of the patient.For this Tele-Medicine System to Measure Heart Rate, Blood Pressure And Alcohol Level project we can add sugar test, now-a-days which is a common disease for a human being.
