What hoses are needed for a refil station

[SHIPCHIEF]

If you look on ebay, under:
Oxygen Transfill Adaptor CGA540 CGA870 Medical Aviation
the one with a pressure gauge is $65, I bought the cheaper one without a gauge, as both bottles have gauges on thier regulators.
It works great. I fill it at my son's shop, from his welding O2 bottle just after he gets in a fresh full one.
This adapter is short, and has a rigid joint to the large bottle, but a hose would add volume = wasted gas. I keep it in my oxygen tool bag of spare parts, hose, cannulas, masks etc. that I accumulated at incredible low prices.
Right now I have two independant systems: C medical bottles, precision 0-8LPM regulators and conserving cannulas. Our Cessna 182 won't go high enough to need a mask.
I am having trouble finding a good location for O2 in my RV-8 project. So far, no one has offered up a really good location. I want to be able to open the bottle in flight, which means having the post valve within reach, having a reach rod, or and expensive solonoid operated valve. I'm reluctant to mount it in the forward baggage for safety reasons.

Here's a link:

with good explanation and lots of pictures about trans filling.
I think their prices look pretty good too, but I've never done business with them.

My setup:

E-size bottle purchased used on eBay: $30 shipped.
CGA-870 0-4LPM mini regulator - eBay $25.95 shipped
2 Chad P-224 Oxymizer cannulas - eBay $50.00 shipped

CPC fittings, same ones MHOxygen sells, direct from manufacturer which is colder.com, without the big markup.

I know nothing about oxygen concentrators.

Can they be used in aircraft?

[Greg Arehart]

Larry,

Yes, but I hope you check the weight and balance on your airplane. These things are fairly heavy, at least the ones I looked at a couple years ago. And they mostly require 110v power. For the price, you can fill a LOT of oxygen bottles.

I'm not a pilot, but am an oxygen user who does many outdoor activities, sometimes at high elevations.

I have an idea that might be helpful, and also wonder if any of you have tried this.

Precision Medical makes makes a portable liquid unit (Easy Mate 6 + 6; Note, the is different from and Easy Mate 6). It can be used on pulse (O2 conservation mode where O2 is only released during inhalation) as well as the standard continuous lpm mode. The O2 connector on the Easy Mate 6 + 6 uses a nasal cannula with only tube, instead of two tubes.

I sometimes use the continuous mode. The Easy Mate 6 + 6 should provide approx 8 hours of continuous O2 set at 2 lpm. But, since it uses a single lumen cannula, I wonder if an oxygen conserving cannula (a reservoir cannula) can be used to make O2 last longer. One brand is Oximizer and I know I saw another on an aviation / sports websites that provide O2 (Cant think of website name).

When using an O2 conserving cannula with standard O2 tanks, your blood should be well saturated with a lower lpm setting, making the tank last longer. For instance, O2 sat using conserving cannula set at 1 lpm should result in the same or better O2 sat than when using a standard cannula set at 2 lpm.

Of course, you do need a separate liquid reservoir to fill these portable tanks. Operating pressure of these portable systems is very low, and I'd think much safer than O2 in standard cylinders.

Do any of you have experience with this? Can you shed some light on my idea?

There are also some very small portable O2 concentrators that are approved for commercial airlines. The smallest do not have a continuous mode, but some do. I like the Inogen One G2, but it still requires power (2 batteries are available that should last 4 and 8 hours)

I just thought of another Portable liquid device that uses a single lumen nasal cannula. It does not have any pulse (O2 conserving settings); just continuous lpm.

A fill would normally last approx 8 hours at 2 lpm with standard cannula. Apparently an O2 conserving cannula allow you to use a lpm setting That'sapprox 1/2 -3/4 of normal required. This device has a max delivery of 6 lpm (the Companion 1000T extends to 15 lpm)

Any thoughts?

Got any ideas on where to fill it up with LO2? How about "on the road"?
