[Tele]Health Update

[Ian Daniher]

There has, in the past few months, been a surge of interest in health and
telehealth applications for the XO.
My own efforts have been focused on telehealth hardware and software
intended for use in scenarios where medical facilities are available but man
hours to manually screen individuals is not. This is a scenario faced in
many large third-world cities in addition to refuge camps.
Codyl and Dirakx have been assisting; Codyl handling the micro-controller
part, Dirakx working with a Columbian team to develop an EKG.

I have designed a Pulse Oximeter based heavily on a communications
photodiode instrumentation amplifier. I have started prototyping over
Christmas break.

I am working with Dirakx and Dr. Dhurjaty to design and prototype an EKG
unit providing valuable diagnostic information about Arrythmia.

Both of these devices will also provide valuable pedagogical resources.


I have designed a server-client infrastructure of the following form for the
THPM activity(telehealth parameterized activity):
A GTK+/PyGTK based gui feeds information into a program which creates an XML
document via PXTL XML templating.
This XML file is uploaded to a server running an httpd and ftpd using the
ftplib python module, along with images in a .jpg format and waveforms in a
.wav format.
The program creates a folder on the server of the following form
/www
/username
/time
/health.xml
/image_of_affected_bodypart1.jpg
/image_of_affected_bodypart2.jpg
/pulseox.wav
/stethescope_and_audio.wav
/ekg.wav
/health.css

>From this structure, a doctor can access a webpage from the url format:
http://server/username/time/health.xml
The XML file will be rendered by a CSS file in the root web directory.


The THM(TeleHealth Module) activity will use code similar to the measure
code to record and then display waveforms inputted via a USB Analog to
Digital Converter.


In addition to all this, there has been a movement to convert the .pdf
Hesperian foundation work *Where There is No Doctor* into [x]html. Pascals
has been heading up this work.


Anyone interested in contributing, feel free to contact me via any of the
below means.
Many thanks,
