Rather than persist with the silly notion that we need nature to run its course for a reason, this little beauty clips to your belt and keeps you cool.
It constantly filters your blood to head off impending infections , running it through a heat exchanger and dropping its temperature just a degree
below normal. This should not be too much shock to the system of the average adult, though it will retard fertility in males. Chill out, all year round, if you live in the tropics.
Obviously it can be run in reverse cycle in winter, to keep you from freezing whilst you wait for the bus. Recharges from mains power weekly.

I really think you should let your body regulate itself and not interfere with nature. just strip off man give the girls a treat. |

While I love the idea, <Had it myself years ago, although only for cooling> it's not really practical...cold blood apparently causes cramps when given to patients; and the two openings through the skin would be a significant source of infection themselves. |
|
| |
I'm not talking about 20 C here Star. Closer to about 36 C, just a little cooler. I was aware of the cramping problem. We had about 39 C here yesterday, so it would have been helpful. |

My Exwife is coldblooded - and as evidenced by the email I got from my daughter a couple of days ago, my daughter is equally coldblooded. Certainly enough to make my own blood boil. |
|
| |
tw, thats wimmin for you! |
|
| |
I hope this wouldn't operate from a MS Windows OS -- what if it bluescreened? |
|
| |
39°C?! Good grief.
Daruma, this sort of device would probably be best if it had no cpu at all. |
|
| |
Wouldn't it be potentially messy if it was external. Have you ever tried getting bloodstains out? What's wrong with a coat and scarf? or a fan? |
|
| |
Isn't the head also a radiator of heat, too? |
|
| |
The head and scalp are a heat exchanger as it stands. Head cuts bleed a *lot* for this very reason. I perceive this to be something grafted into the skin and soft enough to prevent it snagging on things and tearing. |
|
| |
As for operating it from Windows... ugh! Far too prone to virus infections for my liking. |
|
| |
I'd rather have it run from Windows on a PC than from a
Mac :| |
|
| |
[jimithing], I know a lot of people who can run all day on a big Mac. |
|
| |
You mean a big Mac as in the G4 cube or the big Mac as
in the McDonald's sandwich UB? Whichever one you
mean, though -- I'm at a loss of words. I apologize. |
|

Sharper Image has something similar to the 'hand cooler'...A collar with heat conductive plates around your throat, and a small evaporative cooler at the back of your neck. |
|
| |
Unfortunately, these don't work well in humid areas. Moving because it's hot a few days is generally not an option... |
|
| |
Hmm... how about a liquid nitrogen tourniquet? Sure it'd kill the surrounding tissue but might save a life. It beats "putting pressure" on gaping wounds - what is this, the dark ages? |
|
| |
hmmmmmmmmm... prometheus bound for a bloodletting? |
|
| |
[bristolz] - you are correct - the head is an extremely efficient radiator of heat (obviously more so in PeterSealy's case than yours). From various conversations with nurses (after being rushed to hospital with suspected hypothermia) I seem to remember that about 60% of heat is lost from the head. |
|
| |
This device would have numerous medical and surgical applications. |
|
| |
Lotsa Google hits for the "partial bypass" method of routing hypothermia patients' blood through a small heater to warm them up. |
|
| |
with chemistry 10C is like an order of magnitude different enzyme activity thus cooling the blood a degree C is kind of like halving enzyme activity |
|
| |
I've thought that a carotid artery plug cooler could deliver cooler blood to the brain; if you could still think you might have half the rate of brain aging |
|
| |
likewise raise liver temp a few degrees C to rather quickly metabolize poisons; nerve gas attack ---> warm up your liver right away with a warm water pillow or comfy computerized electric blanket that can find your liver |
|
| |
the connector is the iffy part |
|

This is an excellent idea except for the
fatal part. Passing your blood through
any kind of foreign structure for a long
time is likely to activate the clotting
cascade. Artificial heart valves just
about get
away with it, because the surface area/
volume ratio is low (ie, not much
surface contact per unit volume of
blood). But heart/lung machines used
during some surgeries are a big
problem even for the duration of the
operation. |
|
| |
There is a lot of research into inhibiting
key proteases in the clotting cascade,
particularly for administering during
such operations, to prevent clotting.
The main problem is to make them
reversible (or short-lived) so that
normal clotting can resume ASAP after
the operation. Having a filter plumbed
in permanently is not a good plan. |
|
| |
Also, how do you plan to filter out
infectious agents, given that both
bacteria and viruses are smaller than
even red (let alone white) blood cells? |
