That $8 pulse oximeter from aliexpress is better than nothing, but it’s a long way from what Masimo or Medtronic (Nellcor) sell.
And the prices for oximeters aren’t really affected by insurance, as individuals almost never get them at diagnostic grade. They’re durable, have screens that convey more than just a number, electrically isolated from the patient… there’s a lot going on there that is not, at first glance, obvious to the layman.
(I’m an anesthesiologist; pulse oximetry with a good waveform display is a critical monitor for us. I would rather have a good pulse ox than any other non-invasive monitor, if I could only have one.)
As a follow-up, it looks like Masimo is trying to make a consumer watch-like device (or possibly just pretending to so they look like a competitor to Apple). https://www.masimopersonalhealth.com/
Thanks for the info.
Do we know the total BOM cost plus the amortized cost of development & other expenses for an Apple watch ?
While I don't think one patent holder should get a major share of the available margins, I find it hard to believe that margins for Apple on smart watches are anywhere close to "thin".
