Home Emergency Eyewash




Because of my sleep apnea I use a CPAP (Constant Positive Air Pressure) machine so I can sleep better. However because of the way it works it causes my eyes to tear more through the night than they would normally. When I wake up my eyes are covered with a build up of dried tear\s that when I open my eyes and some of it gets into them it really starts to burn.Obviously washing my eyes out in the morning is more than a little important. What I really needed was an emergency eye wash like the one shown in Crucio's NON-EMERGENCY EYEWASH . While Crucio's bottle eyewash is a good idea it doesn't give me what I really need in the morning. I really need to wash my eyes out. So I made my own 2 fountain eye wash.

Step 1: What You Will Need:

Everything is made of 1/2 inch PVC fittings and pipe.
2 - End caps.
1 - T
Enough 1/2 inch pipe to connect them together.

You may also need a 45 Degree elbow. Don't get one unless you know you need one.
You will see why in a little bit.

Since there is no real pressure to speak of you won't need to glue them together. 

Step 2: Let's Get Started.

There is nothing requiring any great precision so you can pretty much "eyeball" everything. Pun not exactly intended. 
First cut two peaces of plastic pipe about 2 1/4 inches in length. Insert them into the end caps and seat them as far as they will go.
Make sure they are seated all the way.

Step 3: Drilling the Holes.

You can now drill the holes for the fountains. Drill each hole into the end caps and into the pipe. Angle the holes so that the streams of water will come toward each other. Again the angle is not critical. Make it as close to the picture as you can is good enough. Make sure you clean up any burrs or drill shavings from your holes and then take out your drill bit and insert the back end of the drill bit into each hole to make sure the hole in the end cap and the pipe are aligned. Also your drill bit will serve as a handle for your next step.

Step 4: Do You Need a 45 Degree Angle?

Your need of a 45 degree elbow depends on what kind of faucet you have. I have a 1 handle faucet and that handle (just out of view in the picture) gets in the way of my head when I use it with out an extension. The 45 degree elbow and 2 1/2 inches of pipe act as an extension to move the two holes away from the handle so that I can use it properly.  Obviously if there is nothing above the place where the water comes out that can get in the way of your head, you don't need it

Step 5: Final Assembly and Adjustment

Go ahead and assemble the peaces together but do not seat them all the way yet, The holes will need to be adjusted.

Take the drill bit and insert the back end into each hole and adjust the holes so that when the center part of the T fitting or the 45 degree elbow is seated over the aerator of the faucet, the two water streams will come together  as in the picture in the previous step.

Once that adjustment is complete, you can push everything together and seat the fittings all the way.

Your done! Now you're ready for your next bout with sore eyes.

Tips of use:
Leave your eye washer near the sink in a place where you can find it with your eyes shut. When you really need it that is probably how you will be looking for it. The same goes for using it. Learn to set it up and use it as though you were blind.

And lastly, this is not a substitute for a real emergency eye wash. If you are a DIYr and whatever you are DIYing involves something that could get into your eyes, you are better off with a real emergency eye wash station.

Take care,
Stay safe.

    What PVC part could you use to connect to the PVC eye part to attach it to your sink

    Actually you don't want to attach it to anything. You simply hold it up against the faucet as shown in the pictures. The half inch fitting fits nicely up against the aerator of the faucet. Even if the fit is not perfect, (mine isn't) it will be good enough to use on any faucet. This is not a permanent installation. You keep it handy for when you need it, stick it under the faucet and adjust the flow so that the water streams aren't too strong and breath a sigh of relief as the water washes the junk out of your eyes.

    If you want a permanent installation, you can use standard plumbing techniques which are outside the scope of this instructable.

    I hope that answers your question.

    Ouch! My eyes sting just thinking about what happened to you. I hope your eyes are OK. There is no substitute for being safety conscious.
    Please take care

    That's a great idea! Gonna have to make me one considering I can be a bit clumsy ? :)

    This would be a good tool for everyone to whip up and keep in their first aid kit. Everyone gets something in their eyes a few times a year, more than enough to justify a dedicated tool. Even better, if you really need an eye wash, you REALLY need an eye wash.

    If your CPAP causes you to tear up all night or get eye gunk, have your mask checked for leaks (most modern machines will record leakage over time). I don't think eye gunk is expected under normal usage.

    That said, this is a neat idea for a sink-based eye-washer! Love the temporary attachment.

    Thank you for your kind words. As far as tearing goes I have been through 3 masks so far and all of them have given me this problem. Adjustment and readjustment is a continuing process because the elastic straps holding the mask in place change their properties over time. Still I sleep bettter with than without it. It's worth the sore eyes in the morning.

    Take care

    It's probably the shape of your face. There is a surprising amount of variability in people's faces and generic, one-size-fits-all mask usually leave at least 10% of users with inferior seals. That is one of the reasons that emergency response planners prefer civilian gas mask that just slip over the entire head.

    The most likely point of leakage is around the nose and where the nose meets the plane of the cheeks. You might be able to fashion a list Sugur or Oogoo "adapter for the area that you could put on to seal against the mask.
