Airbrush Nebulizer Project |
|
I'm not telling anyone to do this. I'm just relating what I am
doing. Remember, nothing in the way of equipment listed here is in
any way approved for medical use.
-
Compressor-
a commonly available small OIL-LESS air compressor; these things
are NOISY. Cost around $150. I bought the smallest & lightest I
could find at the time, since then I've seen a smaller one at
Lowe's.
- Regulator- a commonly available subcompact air pressure line
regulator. These regulators have trouble being reliably
adjustable at below 20psi. These usually come on the compressor
these days.
- Hose- standard black vinyl, red rubber, pvc or urethane air
hose. Cheapest is all I need for this. I'm using the one that
came with the compressor.
-
Airbrush-
Harbor Freight airbrush kit model 1500. Cost me $25 with
shipping. HF is terminally slow with the cheapest shipping
option. It took two weeks to get here and their distribution
center is 100 miles away.
- Standard brass 1/4" quick disconnect fittings between the
regulator and main hose, and between the main hose and the small
airbrush hose in the kit.
The kit comes with two glass bottles, I use the smaller one. The
metal "cup" is useless for this purpose. Save the larger bottle in
case the small one gets broken.
At 15 psi, this airbrush puts a out a fine mist that appears to
be every bit as fine as the mist form the nebulizer I've used for
years. The main difference is that it is pressurized. A nebulizer
chamber atomizes the liquid but disperses the pressure, so there is
no pressure into the mouth. Disadvantage- makes me want to resist
breathing it; Advantage- would be good if breathing were difficult.
20 psi is too much. This is not for a child to use unless an adult
is controlling the trigger. There is an adjustment at the nose of
the airbrush, keep it tight for finest mist.
At 15psi, I have the option of closing my mouth around it or
holding it out of my mouth and breathing the mist.
The really big advantage is that this arrangement will conserve
both the CS mixture and the air used. The compressor won't run
nearly as much as with a nebulizer chamber since I am shutting the
air off after every breath. This would be particularly advantageous
if hooked it to a bottle of oxygen (with an oxy regulator!!!). If I
have to stop, I don't have to get up and cut the air off, but of
course that could be fixed on a nebulizer with a valve in-line close
to me.
Speaking of oxygen, you can buy small tanks with some metal
cutting torch outfits. I came upon mine, brand new, because someone
traded in one of those tanks for a larger one at my local welding
shop. I bought the tank for $50.
The trigger is a button on top that has a double action. You must
depress it and pull it back to get full fog. If you don't pull it
back you're only getting air.
This was worth doing to me, but then I love playing with this
kinda stuff. Guy Thing.
