Fragrance said:artem said:Do you have any info about medical opto sensors using photodiod for heart beat signal detection ?
hi friend it is new for you that i am electronics engineer but working as biomedical engineer since from 1992, have expirence on ziess laser and opth medical equepments such as autoref, field analyzer, pulse oxi meter and nibp monitor a long rang on which i have worked
here is some for you
heart beat or pulse oxi meter probe consist of high bright red led and a ir led plus bpw34 photo diode from siemens
the working princepal is very clear red light absrobe by homuglobin and the percenttage of absordtion is counted by photo diode for heart beat
and other led which is ir show the percenttage of air in bloob if you need more information i will send you
regards
Fragrance
makswell said:I am interested about the optical methods used today. In laboratories their meters based on by using laser beam. I don't know how these meters work, but I'd like know more about optical methods. Same principle as oxygen is measured from the finger.
I know that there are information about that, because meters based on this method are developing. It will take time when diabetics can buy them. Meters should work quite wide clucose consentration range abt. 0...30 mmol/l.
I am not designing or developing this kind of meter, but I'm only interested that as diabetic.
If you have any link where to read about meters based on optical methods I'd be grateful.
artem said:Hi
I am actually asking on behalf of my friend
He wass dealing with health irregularity detection by
heart bit signal autocorrelation analysis . He designed 2 types of sensors to get heatbeat signal -
pressure based and opto based .
General problem with those are it is impossible to get similar results from all probed patient so signal had to be adapted before actual processing could be done .
I was just asking to know is there ready to use sensor solutions already available for use in mass production .Otherwise my friend has to deal with sensor design . Some info could be found in Biomedical engineering book from mcu.czc .
Thanks for reply

Please Fragrance can u mail it to the following email: cario(at)seed.net.tw
