In our last two posts we have been talking about the software side of the project i.e; eclipse projects,various frameworks etc. Through this post we would like to throw some light on the hardware side too, i.e; sensors. The post guides you about the vital bio-medical sensors which we would be using to record patient's parameters.
For selecting these sensors we have taken following factors into consideration:
Doctors: we have consulted with various doctors ,to get acquainted with the type of data (parameters) required for primary diagnosis of a patient.
Invasive/Non-invasive: All the sensors, which we are using for our project are non invasive,so that any kind of infection can be avoided.
Cost: For the time being we are focusing on primary diagnosis of patient, hence we have avoided using costly complex bio-medical sensors.
We are going forward with following sensors. Once we have successfully interfaced these, we would add more,to make the diagnosis more useful.
1.Three Electrode ECG sensor:
We would be using it to monitor the ECG interval of a patient.The three electrodes are placed .The ECG is separated into two basic Intervals, the PR Interval and the QT Interval, described below.
For more details on ECG, follow the link below:
Electrocardiography
2.Pulse Sensor:
It is a noninvasive method for monitoring a person's oxygen saturation (SO2). Its reading of SpO2 (peripheral oxygen saturation) is not always identical to the reading of SaO2 (arterial oxygen saturation) from arterial blood gas analysis, but the two are reliably enough correlated that the safe, convenient, noninvasive, inexpensive pulse oximetry method is valuable for measuring oxygen saturation in clinical use.
To know more about this sensor, follow the link below:
Pulse oximetry
3.GSR Sensor:
GSR, standing for galvanic skin response, is a method of measuring the electrical conductance of the skin. Strong emotion can cause stimulus to your sympathetic nervous system, resulting more sweat being secreted by the sweat glands.GSR allows you to spot such strong emotions by simple attaching two electrodes to two fingers on one hand, an interesting gear to create emotion related projects, like sleep quality monitor.
4.Temperature Sensor:
Temperature sensor would be used to monitor the patient's body temperature.We are using a waterproof temperature sensor.
This was just a getting started guide,in coming weeks we would be diving deeper into the sensors. We would upload more information such as:
1.Schematics
2.PCB
3.Datasheets
4.Hookup Guide
Please stay tuned and give your valuable feedback about the project.
