A computerized stethoscope for home use | |
At a time where restaurants are getting defibrilators, it seems that requiring a doctor visit to find out if you're just being your usual hypochondriac self or in fact you have a walking pneumonia is absurd.
At the same time, many people who tend to NOT go to the doctor with what seems like simply
a nasty flu are putting themselves at risk.
This type of system, using accoustic analysis with a stethoscope would provide an initial diagnosis, with a healthy margin for error on the side of caution.
Or, just use a cell phone

Though they focus on notification, the software is key. [theircompetitor, Nov 14 2009]

I think you need an x-ray to diagnose pnuemonia.
If not, this is interesting. |
|
| |
Ummmm.........nah. If it tells you your sick, wont the doctor still check you, again. |
|
| |
Zimmy, a doctor is able to hear if your lungs are clear, and identify other problems, including heart function. Since the input is sound, it stands to reason this sound can be analyzed by software |
|
| |
I think I might be a hypochondriac...I have all the classic symptoms. I'm going to talk to my doctor, and see if he can prescribe me a placebo. |
|
| |
I tried being a hypochondriac for awhile, but I got sick of it. |
|
| |
I double checked. It seems you can diagnose w/ a stethescope. The x-ray & lab work confirm & determine the type/severity. |
|
| |
+ When I had it, I definately knew something was not right. |
|
| |
One only serves to confirm the other. Xrays and lung sounds. |
|

" Since the input is sound, it stands to reason this sound can be analyzed by software" |
|
| |
Maybe if you, I, or [Jutta] wrote it. My faith in the general world is faint (cough, cough). |
|
| |
Good point :) I think though this kind of objective, rather than subjective diagnostic tool development is key to actually both improving medicine and reducing cost -- that's the point that the linked article makes. |

Why was this idea not brought to my attention before? It's
quite a good one. Most of the things doctors listen for
with a stethoscope are not too subtle. In the case of
lungs, it's basically "crackling" towards the bottom of the
lungs (indicating a deeper infection). In terms of heart
sounds, they aren't really any more complex than the
electrical signals which an automatic defibrillator monitors
before delivering a shock. |
|
| |
So, reasonable software could probably do a decent job of
triage at least. And, if this can be done by cellphone,
then even better. |
|

// software could probably do a decent job of triage // |
|
| |
You could start out with a basic "silence detector". An absence of respiration is widely considered reasonable evidence of something serious. |
|
| |
Or there could be a button which you don't press if you're
dead. |
|
| |
//basically "crackling" towards the bottom of the lungs//
Also wheezes, rhonchi, decreased breath sounds, and
pleural
rubs. Oh, and the seldom-heard mediastinal crunch
(forgot
about that one). And *not*
only at the bottom of the lungs. If you do it right, you
check
each lobe individually. Not that many people do,
anymore. |
|
| |
//a button which you don't press if you're dead// AKA a
dead-
man switch. Not to be confused with the button the
executioner presses in places where the Electric Chair is
still used. |
