Heat Compress Project (for chalazia\styes)

I have started a project to come up with a home-made heat compress
device <a

I do recall reading someone here has built something like this, but I
have not been able to find the post again. If you have any ideas please
reply here or at the link above.. thanks.

Here is a copy of the top post of the thread:

Heat Compress Device Project

The purpose of this project is to come up with a homemade device to aid
in heat compresses for chalazia and styes, with the idea being that the
plethora of methods of applying heat compresses are all troublesome and
impractical. Here are the most widely used compress methods circulated:

1.) Heat compresses with a cloth soaked in hot water from a
stove\microwave.
2.) Heat compresses with hot objects such as hot tea bags, potatoes, a
coffee cup against the eyelid, etc.
3.) Applying hot steam with hot water or with the use of a steam
inhaler\face steamer.

With the heat being strong and constant, the 3rd method seems to be the
most effective in causing chalazia to drain, however steaming methods
will eventually result in extreme skin dryness, cracking, possible
bleeding, and may turn your skin leathery, effectually aggravating the
condition.

The other methods are not so hard on the eyes, but are a hassle to deal
with. If a device existed that eliminated the need for the above,
things would become much easier. Basically all that is needed is a
continuous heat source and surely there is something that could be
homemade or possibly there is something even already existing. If you
are aware of anything or have any ideas please reply. This top thread
will be updated as any progress is made.
