Medical Sensors

Hi,

I'm working now in a new project for medical purposes in which we will use some sensors to monitor a patient and collect data in arduino which sends the processed data to a PC using RF transmitter/receiver.

We have two options regarding the sensors: 1) build them, which will be a difficult process. 2) buy them, but the problem i don't know where I can find a company that provides reliable medical sensors.

The sensors I'm looking for: - temp. sensor - Blood Volume Pulse (BVP) - Blood Pressure - Galvanic Skin Conductance.

So please, I need your advise and help to find reliable medical sensors that can be interfaced easily with arduino board.

regards,

There are temperature sensors everywhere.

The other ones are a bit trickier.

The most widely used medical temperature probes are from Yellow springs instruments. They are thermistors that change resistance with temperature. See http://www.ysitemperature.com/med-probes.html

Hey!

Don't know how much this is worth, but the Lego Mindstorms unit, like the Arduino, has 10-bit resolution on it's inputs. This very simple setup works to the point of beeing able to tell when someone gets a bit stressed (like when telling a lie). http://extremenxt.com/gsr.htm Hope it helps!
