How to Make a "Medical Monitor with an Emotional Stress and/or Pain Indicator and Biofeedback"


Typically, Medical Monitors only display the Patient's Vital Signs. - This new Medical Monitor indicates Emotional Stress and/or Pain, too.




This new monitor provides an External Indicator e.g. colored lights to show the Internal Distress/Pain Condition of a person, e.g. a Patient - and provides a means to assist a person, e.g. a Patient, to Reduce their Distress/Pain by Relaxation Means, e.g. Deep, Slow Breathing.


See this Video to see How It Works, Theory of Operation, Applications, etc. - Medical Monitor with an Emotional Stress And/or Pain Indicator - Explanation Video.


***************************
There are two versions of this concept – one uses Skin Conductance or Galvanic Skin Response (GSR) and the other uses Heart Rate Variability (HRV).


****************************** 


This Blog Post shows how the make the Skin Conductance Version (GSR). (My Working Model is not for sale – but you can make your own – and make it even better than I did!) 


The HRV version is being worked on and will be revealed soon.

*********************

Here's the Big Picture of my Working Model:


See Parts List.


Here's How I Made it.... 


1. Make a Medical Monitor Simulator to illustrate the total concept of a “Medical Monitor with an Emotional Stress And/or Pain Indicators”. I just used a picture of a typical Medical Monitor with "Emotional Stress And/or Pain Indicators" glued onto the picture.



















Of course, you could modify an actual existing Medical Monitor to add the "Emotional Stress And/or Pain Indicators", too.

2. Make a Patient Wrist Band that measures skin conductance or heart rate variability (HRV). For my GSR version, I made a wrist band with copper sensors glued on - instead of the finger sensors that came with the Grove GSR Sensor.

(On the HRV version, glue the Heart Pulse Sensor onto the wrist band instead of the GSR copper sensors.)






3. Make a Patient Bedside Console with “Emotional Stress And/or Pain Indicators” and also Biofeedback indicators to help patient relax. I just used a hacked up old TV Remote to illustrate the concept.



The upper horizontal string Green, Yellow, and Red Led's are the "Emotional Stress And/or Pain Indicators", same as on the Medical Monitor.


The Two Blue vertical Led's below them are the Patient Biofeedback Breathing Pacer Indicators.


4 Wire an Arduino Uno according to this Wiring Diagram, referring the Parts List.










5. Program the Arduino with this Sketch. (Copy and Paste into Arduino) - If you don't like the transition between Red, Yellow, and Green - try experimenting with with the sensorValue portion of the sketch that turns on and off the R, Y, G led's.


6. Replay this Video to see how to work the system and try it out.


*******************
The "heart" of this model are the sensors:

* For Skin Conductance, the Grove GSR Sensor - Video1

* For Heart Rate Variability, the PulseSensor - and HRV - Scroll down to this Video


More Videos/Pictures.

This concept was shown by me at a local Maker Faire, last year.




Here's some Emotion Wearables to build your work on, too.

Good Luck!
